Zloženie hydraulického injektážneho spojivaComposition of hydraulic injection binder
Oblasť technikyTechnical field
Predložený vynález rieši zloženie hydraulického spojiva na výrobu injektážnych suspenzii, ktoré sú vhodné na vtlačenie nízkotlakovou injektážou do pôd alebo hornín alebo podobne na utesnenie alebo spevnenie.The present invention provides a hydraulic binder composition for the production of injection suspensions which are suitable for injection by low pressure injection into soils or rocks or the like for sealing or reinforcing.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Je známe použitie injektážnych suspenzií na spevnenie alebo utesnenie pôd alebo horniny so zloženiami spojiva, ktoré majú hlavne vedľa cementov bez obsahu síranového nosiča vždy bentonitovú prísadu (Charvát, I.: Special clay-cement mixtures for injection and grouting, Práce Výzkumného ústavu geologického inženýrství, zv. XXXDC, Brno, 1987). Bentonitová prísada je medzi 2 až 15 % hmotn. a slúži na stabilizáciu suspenzie proti usadzovaniu čiastočiek pevnej látky. Používa sa slinková múčka s jemnosťou 7 200 cm2/g. Je popísaný predpis na utesnenie spevnenia, ktorý sa mení v množstve bentonitu a hodnote spojiva tuhnutia pod vodou (vodného súčiniteľa).It is known to use grouting suspensions for reinforcing or sealing soil or rock with binder compositions which, in addition to sulfate-free cements, always have a bentonite additive (Charvát, I .: Special Clay-Cement Mixtures for Injection and Grouting, Research Institute of Geological Engineering, Vol XXXDC, Brno, 1987). The bentonite additive is between 2 and 15 wt. and serves to stabilize the suspension against settling of solid particles. A clinker meal with a fineness of 7 200 cm 2 / g is used. A prescription for sealing reinforcement is described, which varies in the amount of bentonite and the value of the binder of solidification under water (water coefficient).
V patentovom spise CS 260 577 je popísaná injektážna suspenzia na utesnenie alebo spevnenie horniny a nespevnené zeminy, ktorá je založená na slinkovej múčke so špecifickými povrchmi nad 6 000 cm2/g. Suspenzia obsahuje menej ako 3 %hmotn. lignínsulfonátu alebo podobne, až 3 % hmotn. alkalického uhličitanu a prípadne spomaľovač na základe organických kyselín. Použitie pri nízkotlakovej injektáži eventuálne penetračnej injektáži, pri ktorej sa používajú tlaky pod 100 bar, a ktoré sa vyznačuje tým, že sa zloženie injektovanej pôdy alebo horniny nezničí, popísané nie je. Skôr sa uvádza, že sa majú spevniť pôdy s každou jemnosťou, z čoho vyplýva, že má byť použitá v každom prípade vysokotlaková injektáž.CS 260 577 discloses an injection suspension for sealing or consolidating rock and non-compacted soil, based on clinker meal with specific surfaces above 6,000 cm 2 / g. The suspension contains less than 3 wt. % lignin sulfonate or the like, up to 3 wt. alkali carbonate and optionally an organic acid retarder. The use in low pressure grouting or penetration grouting using pressures below 100 bar and characterized in that the composition of the injected soil or rock is not destroyed is not described. Rather, it is stated that the soil should be consolidated with every fineness, which implies that in any case high-pressure grouting should be used.
Podľa stavu techniky je obmedzené použitie suspenzií s obsahom pevných látok na pôdach s podielom veľmi jemného piesku (veľkosť zŕn < 2 mm) až na 90 %. Od podielu prachu (veľkosť zŕn < 0,063 mm) cca 10 % nie je nízkotlaková injektáž možná suspenziami s obsahom veľmi jemných pevných látok.According to the prior art, the use of solids suspensions on soils with a very fine sand content (grain size <2 mm) is limited to 90%. From a dust content (grain size <0.063 mm) of about 10%, low pressure injection is not possible with suspensions containing very fine solids.
Podstata vynálezu fSUMMARY OF THE INVENTION f
Úlohou vynálezu je uviesť zloženie hydraulických spojív, ktoré sú vhodné, aby sa použili pri nízkotlakovej injektáži (< 100 bar tlak vtláčania ) a sú predovšetkým vhodné na utesnenie a spevnenie tiež pôd s obsahom podielu prachu cca 10 % a viacej, pričom majú byť vyrobiteľné injektážne suspenzie so zložení spojív, ktoré sú stabilné, pokiaľ ide o sedimentáciu a majú zlepšenú schopnosť vniknutia.SUMMARY OF THE INVENTION It is an object of the present invention to provide hydraulic binder compositions which are suitable for use in low pressure injection (< 100 bar injection pressure) and are particularly suitable for sealing and consolidating soils with a dust content of about 10% or more. suspensions with binder compositions that are stable in sedimentation and have improved penetration properties.
Táto úloha je riešená znakmi nároku 1. Ďalšie formy uskutočnenia vynálezu sú uvedené v závislých nárokoch.This object is solved by the features of claim 1. Further embodiments of the invention are set out in the dependent claims.
Podstatné je to, že sa používajú veľmi jemné slinkové múčky bez obsahu síranového nosiča s rôznou jemnosťou, napr. múčky s dg5< 25 gm alebo dg5< 16 gm alebo d«< 9 gm alebo d«< 6,5 gm. Tieto slinkové múčky môžu byť kombinované aspoň s inertnou jemne mletou kamennou múčkou, napr. s vápencovou múčkou alebo s aspoň jednou pucolánovou látkou ako trasom, mikrokremičitanmi, lietavým popolčekom, metakaolinitom, zeolitom neupravenými alebo temperovanými alebo s aspoň jednou latentnou hydraulickou látkou ako múčkou hutníckeho piesku s rovnakou alebo vyššou jemnosťou. Okrem toho môžu byť obsiahnuté ďalšie hydraulické látky ako kremičitany vápenaté alebo hlinitany vápenaté, samotné alebo v kombinácii.It is essential that very fine, non-sulphate carrier-free clinker meal with different fineness, e.g. meal 5 with d <25 gm and d 5 <16 gm or C '<9 gm or C'<6.5 gm. These clinker meals may be combined with at least an inert finely ground stone meal, e.g. with limestone meal or at least one pozzolanic substance such as traces, microsilicates, fly ash, metakaolinite, unprocessed or tempered zeolites, or with at least one latent hydraulic substance as metallurgical sand meal of equal or higher fineness. In addition, other hydraulic substances, such as calcium silicates or calcium aluminates, may be included alone or in combination.
Zloženie spojiva obsahuje okrem toho aspoň jeden spomaľovač tuhnutia, pripadne plastifikujúci spomaľovač tuhnutia. Do tejto skupiny prísad patria taktiež étery celulózy (metyl-, etyl- alebo propyléter); alebo polysacharidy (fruktóza, glukóza atď.); akrylová kyselina a jej soli; oxykarboxylové kyseliny a jej soli (napr. kyselina citrónová); fosforečné kyseliny a jej soli; kyselina boritá a jej soli; alkylamidy; styrénbutadién.In addition, the binder composition comprises at least one solidification retarder, optionally a plasticizing solidification retarder. Cellulose ethers (methyl, ethyl or propyl ether) also belong to this group of additives; or polysaccharides (fructose, glucose, etc.); acrylic acid and its salts; oxycarboxylic acids and salts thereof (e.g., citric acid); phosphoric acid and its salts; boric acid and its salts; alkylamides; styrene butadiene.
Zloženie spojiva podľa vynálezu môže obsahovať tiež urýchľovač. Urýchľovače môžu byť nasledujúce prísady: alkalické uhličitany alebo alkalické hydrouhličitany; dusičnan vápenatý CaíNCbh ; alkalické kremičitany; hydroxidy kovov alkalických zemín (napr. Ba(OH>2); chloridy viacmocných katiónov (napr. CaCb, CrClj); alkalické sírany; alkalické pyrosiričitany (napr. K.2S2O5); amínové zlúčeniny (napr. trietanolamín); kalciumformiát.The binder composition of the invention may also contain an accelerator. The accelerators may be the following additives: alkali carbonates or alkaline bicarbonates; calcium nitrate Ca 1 CNCl 2; alkali silicates; alkaline earth metal hydroxides (e.g. Ba (OH> 2); polyvalent cations chlorides (e.g. CaCl 2, CrCl 3); alkali sulfates; alkaline pyrosulphites (e.g. K 2 S 2 O 5); amine compounds (e.g. triethanolamine); calcium formate.
Zloženie spojiva podľa vynálezu má okrem toho aspoň jeden stekuťovač, napr. obsahuje stekuťovač bez sulfonátových skupín, príkladne polykarboxylát, predovšetkým modifikovaný polykarboxylát, ktoré sú popísané napríklad v spise DE 196 53 524 Al. Ďalej je taktiež možné použiť namiesto polykarboxylátov eventuálne iné známe stekuťovače bez sulfonátových nosičov, predovšetkým ale v kombinácii. Príkladne sú tieto prísady zo skupiny polyakrylátov alebo polyasparagínových kyselín; posledné sa môžu počítať tiež k polykarboxylátom. Pri polykarboxylátoch ide väčšinou o homoalebo kopolyméry monomérov, obsahujúcich karboxylové skupiny, ktorých bočné reťazce sú modifikované (ConChem-Joumal, 5. Ročník 4/97, s. 147). Ďalšími vhodnými stekuťovačmi sú napríklad lignínsulfonáty, sulfonované melamínformaldehydové živice a naftalénsulfonáty.In addition, the binder composition according to the invention has at least one fluidiser, e.g. it comprises a sulfonate-free flowing agent, for example a polycarboxylate, in particular a modified polycarboxylate, as described, for example, in DE 196 53 524 A1. Furthermore, it is also possible to use, in place of the polycarboxylates, possibly other known flowers without sulfonate carriers, in particular in combination. By way of example, these additives are from the group of polyacrylates or polyasparaginic acids; the latter may also be included with polycarboxylates. Polycarboxylates are mostly homo- or copolymers of monomers containing carboxyl groups whose side chains are modified (ConChem-Joumal, 5th Edition 4/97, p. 147). Other suitable flowers are, for example, lignin sulfonates, sulfonated melamine formaldehyde resins, and naphthalenesulfonates.
Jemnosť zloženia spojiva závisí na šírke dutiny dutinového systému, ktorý je potrebné injektovať v hornine alebo na podiele jemného piesku eventuálne na podiele pôdy, ktorou je potrebné injektovať. Okrem toho je potrebné určiť množstvo prísady na jemnosť spojiva.The fineness of the binder composition depends on the cavity width of the cavity system to be injected in the rock or the proportion of fine sand or the proportion of soil to be injected. In addition, it is necessary to determine the amount of binder fineness additive.
Zo zloženia spojív podľa vynálezu môžu byť vyrobené injekcie na spevnenie alebo utesnenie nesúdržnej horniny. Injektážne suspenzie sú okrem toho použiteľné na imobilizáciu škodlivín v pôdach a na spevňujúce alebo utesňujúce injektáže horniny (dutiny). Pritom záleží na tom, aby dutinové injektážne horniny pôsobili utesňujúco rýchlo.Injectables may be made from the binder composition of the invention to strengthen or seal incoherent rock. Injectable suspensions are also useful for immobilizing pollutants in soils and for reinforcing or sealing grouting of rock (cavities). Here, it is important that the cavity injection rocks act as a sealing agent rapidly.
Suspenzie zo zloženia spojiva podľa vynálezu poskytujú značne zlepšenú injektáž pri nízkom injektážnom tlaku, rýchly vývoj počiatočnej pevnosti s vyššími počiatočnými pevnosťami alebo lepším tesniacim účinkom pri teplotách predovšetkým medzi 5 až 15°C. Suspenzie sú okrem toho únosné pre životné prostredie - čo je prospešné pre bezpečnosť práce - s malým obsahom chrómu. Do tej miery nespôsobujú žiadne príslušné ochorenia napr. alergie.Suspensions of the binder composition according to the invention provide considerably improved injection at low injection pressure, rapid development of initial strength with higher initial strengths or better sealing effect at temperatures in particular between 5 and 15 ° C. In addition, suspensions are environmentally acceptable - which is beneficial for safety at work - with a low chromium content. To this extent, they do not cause any relevant diseases e.g. allergies.

Nasledujúce dva príklady 4 a 5 objasňujú účinok vynálezu.The following two examples 4 and 5 illustrate the effect of the invention.
Pri príkladoch 4 a 5 boli uskutočňované injektážne pokusy v laboratóriu. Injektážna schopnosť injektážnych spojív môže byť skúšaná v laboratórnom meradle napríklad podľa „predbežného predpisu pre vtláčacie práce s veľmi jemnými spojivami do nespevnenej zeminy“. Tu sa skúšajú injektážne spojivá v jednorozmernom pokuse prietoku na definovaných modelových pieskoch. Výška inštalovaného modelového piesku v skúšobných valcoch musí byť aspoň 20 cm. Injektážne spojivo sa posúdi ako „schopné injektáže“, ak je možný dvoj až trojnásobný prietok modelového piesku injektážnym tlakom maximálne 6 bar.In Examples 4 and 5, injection experiments were carried out in the laboratory. The grouting ability of grouting binders can be tested on a laboratory scale, for example, according to the "preliminary rule for injection works with very fine binders into unpaved soil". Here grouting binders are tested in a one-dimensional flow test on defined model sands. The height of the model sand installed in the test rollers shall be at least 20 cm. The grouting binder shall be considered as 'capable of grouting' if two to three times the flow of model sand at an injection pressure of a maximum of 6 bar is possible.
Príklad 4Example 4
V príklade 4 sa použije predpis injektážnej suspenzie s nasledujúcim zložením:In Example 4, a suspension for injection with the following composition is used:
slinková múčka portlandského cementu s obsahom síranového nosičaPortland cement clinker meal containing sulphate support
0,5 % hmotn. spomaľovač (kyselina citrónová)0.5 wt. retarder (citric acid)
1,0 % hmotn. stekuťovač (naftalčnsulfonát)1.0 wt. Strainer (Naphthalenesulfonate)
0,03 % hmotn. stabilizátor (xantán) hodnota tuhnutia spojiva pod vodou: 0,9 (vodný súčiniteľ)0.03 wt. stabilizer (xanthan) binder solidification value under water: 0.9 (water coefficient)
Rozdelenie veľkosti zŕn v suspenzii predstavovalo: d95< 9,5 pm. Čas výtoku suspenzie po pretoku predstavoval pod 40 sekúnd. Sedimentácia bola 0 %.The grain size distribution of the suspension was: d95 <9.5 µm. The slurry flow time after the protocol was below 40 seconds. Sedimentation was 0%.
Ako modelový piesok bol použitý kremenný piesok (typ: F31) s jemným podielom cca 20 % hmotn.< 0,2 mm.Quartz sand (type: F31) with a fine fraction of about 20% by weight <0.2 mm was used as model sand.
Ako injekčná schopnosť vyplývala z dvojnásobného prietoku modelového piesku injekčným tlakom cca 6 bar.The injection capability resulted from a double flow of model sand at an injection pressure of about 6 bar.
Príklad 5Example 5
Podľa príkladu 5 bol použitý rovnaký predpis ako v príklade 4. Na rozdiel od príkladu 4 bola však použitá slinková múčka portlandského cementu bez síranového nosiča.According to Example 5, the same formulation as in Example 4 was used. However, unlike Example 4, Portland cement clinker meal without a sulphate carrier was used.
Prekvapivo mohlo byť dosiahnuté štvornásobného prietoku modelového piesku injektážnym tlakom cca 1 bar. Z tohto výsledku vyplýva značne zlepšená injektáž ako v príklade 1.Surprisingly, a quadruple flow of model sand could be achieved with an injection pressure of about 1 bar. This results in a significantly improved injection as in Example 1.
Prekvapivý účinok vyplýva z použitia vybraného stabilizátora. Podľa vynálezu sa používa stabilizátor zo skupiny mikrobiálnych polysacharidov. Týmito sú syntetické biopolyméry, z ktorých sú na účely podľa vynálezu predovšetkým vhodné xantán a welan.The surprising effect results from the use of the selected stabilizer. According to the invention, a stabilizer from the group of microbial polysaccharides is used. These are synthetic biopolymers of which xanthan and welan are particularly suitable for the purposes of the invention.
Predovšetkým vhodné biopolyméry sú popísané napr. vo Velco Prospekt: „Xantan Gum“, str. 1 až 24 a pomenované predovšetkým na str. 1 stĺpec „Microbial polysacharides“. Ide o dextran, gelanovú živicu, rhansanovú živicu, welanovú živicu, xantanovú živicu.Particularly suitable biopolymers are described e.g. in Velco Prospectus: “Xantan Gum”, p. 1 to 24 and named in particular on p. 1 column "Microbial polysaccharides". These are dextran, gelan resin, rhansan resin, welan resin, xanthan resin.
Je prekvapivé, že použitie stabilizátora, ktorý pravidelne zvyšuje injektážny tlak, vedie k značne zlepšenej injektovateľnosti, keď sa vykoná zvláštny výber. Vybrané mikrobiálne polysacharidy pôsobia kombinatoricky s použitím bezsíranového hydraulického veľmi jemného spojiva. Tento prekvapivý účinok vyplýva z príkladu 4 a 5.Surprisingly, the use of a stabilizer that regularly increases the injection pressure results in a significantly improved injectability when a special selection is made. Selected microbial polysaccharides act combinatorically using a sulfur-free hydraulic ultrafine binder. This surprising effect results from Examples 4 and 5.
Použitie bezsíranového spojiva prispieva k tomu, že suspenzia je bezchrómatová, pretože sa komponenty chrómu nadväzujú v jemnej slinkovej múčke hydrátovými fázami. Tak ďaleko plynie synergický efekt.The use of a sulfur-free binder contributes to the suspension being chromium-free, since the chromium components bind in the fine clinker meal by the hydrate phases. So far, there is a synergistic effect.
Suspenzie, vyrobené zo zloženia hydraulického injektážneho spojiva, ukazujú zlepšený priebeh tuhnutia a vyššie hodnoty počiatočnej pevnosti k skoršiemu okamžiku. Či z toho vyplýva zvláštny účinok nie je ešte známe. Ako stekuťovače sú obzvlášť účinné taktiež karboxyláty, pretože umožňujú, aby sa mohol presnejšie nastaviť spomaľovací čas tuhnutia. Ďalšia možnosť konania vyplýva z použitia zmitostných frakcií spojiva, v ktorých sú vypustené podiely pod určitou veľkosťou zŕn. Napríklad môže byť použité spojivo s veľmi jemnými podielmi medzi 6 až 16 gm, aby sa reguloval dodatočne čas spomalenia tuhnutia.Suspensions made from a hydraulic injection binder composition show improved setting behavior and higher initial strength values at an earlier time. Whether this results in a special effect is not yet known. Carboxylates are also particularly effective as fluidizers, since they allow the solidification retardation time to be more accurately set. Another possibility of action arises from the use of special binder fractions in which the proportions are discharged below a certain grain size. For example, a binder with very fine fractions of between 6 to 16 gm may be used to additionally control the solidification retardation time.
