CONSTRUCȚIE INDUSTRIALĂ MULTIETAJATĂ IMERSATĂÎN LACURI TERESTRE SAU IN APE MARINE SI PROCEDEUL DE EXECUȚIE AL ACESTEIAMULTI-STAGE INDUSTRIAL CONSTRUCTION IMMERSED IN LAND LAND OR MARINE WATERS AND ITS EXECUTION PROCEDURE

DESCRIEREA INVENȚIEI 9DESCRIPTION OF THE INVENTION 9

Dezvoltarea de noi tehnologii și de noi condiții aferente acestora reclamă, în unele cazuri, activități submarine la adâncimi de ordinul sutelor de metri. în anii 70-80 ai secolului 20 au fost realizate batiscafuri care au permis activități la sub 200 m, dar erau de dimensiuni relativ mici și aerul respirabil din interior era asigurat din butelii, obligând operatorii să stea în camere barice la încheierea misiunii, pentru reacomodarea cu aerul atmosferic de la suprafață.The development of new technologies and new conditions related to them requires, in some cases, underwater activities at depths of hundreds of meters. In the 70s and 80s of the 20th century, bathyscaphes were built that allowed activities below 200 m, but were relatively small and the breathable air inside was provided by bottles, forcing operators to stay in barrel rooms at the end of the mission, to accommodate with atmospheric air from the surface.

Prezentul brevet prezintă o variantă de structurare a unei construcții industriale multietajată imersată în lacuri terestre sau în ape marine la adâncimi de 20- 200 m și procedeul de execuție al acesteia. în toate încăperile acestor construcții în care va fi necesară prezența umană, se va lucra la presiunea atmosferică a aerului.The present patent presents a variant of structuring a multi-storey industrial construction immersed in terrestrial lakes or in marine waters at depths of 20-200 m and its execution process. In all rooms of these constructions where human presence will be required, atmospheric air pressure will be worked on.

Date fiind presiunile apei la adâncimile vizate pentru imersia construcției, forma ideală ar fi cea sferică. Se pot imagina combinații diverse formate din îngemănarea de sfere, dar ansamblul astfel format ar crește substanțial costul activităților industriale prin gradul redus de ocupare a volumului și prin cheltuieli sporite pentru menținerea flotabilității. De aceea, pentru construcții industriale, sunt preferabile formele cilindrică, elipsoidală și ovoidală, care permit o bună ocupare perimetrală. Desigur că și la aceste forme se pot realiza ansambluri de mai multe structuri lucrând compact, spre exemplu două sau mai multe clădiri unite printr-o alta, care este destinată utilităților comune: scări, lifturi, spații pentru birouri, grupuri sanitare, vestiare, centrale de ventilație, stații de compresoare de aer, generatoare electrice, etc. Evident că și înălțimile construcțiilor din astfel de ansambluri pot fi diferite, funcție de destinația lor. în varianta în care componente ale ansamblului sunt subacvatice, acestea vor avea capace din beton cu armături rigide, de o formă curbată , pentru a suporta relativ ușor presiunea coloanei de lichid.Given the water pressures at the intended depths for the immersion of the construction, the ideal shape would be spherical. One can imagine various combinations consisting of the twinning of spheres, but the ensemble thus formed would substantially increase the cost of industrial activities by the low degree of volume occupancy and by increased expenditures to maintain buoyancy. Therefore, for industrial constructions, cylindrical, ellipsoidal and ovoid shapes are preferable, which allow a good perimeter occupation. Of course, even in these forms it is possible to make assemblies of several structures working compactly, for example two or more buildings joined by another, which is intended for common utilities: stairs, elevators, office space, bathrooms, locker rooms, power plants ventilation, air compressor stations, electric generators, etc. Obviously, the heights of the constructions in such ensembles can also be different, depending on their destination. In the case where the components of the assembly are underwater, they will have rigid, curved-reinforced concrete caps to withstand the pressure of the liquid column relatively easily.

Construcția industrială multietajată va fi alcătuită dintr-o structură prefabricată (stâlpi, grinzi, planșee) din metal, închisă într-o carcasă cilindrică, elipsoidală sau ovoidală realizată din beton cu armături rigide, care să reziste la presiunea coloanei de lichid a mediului ambiant. Betonul armat constituie varianta optimă de protecție la un preț competitiv a construcției față de agresivitatea apelor ambientale. Construcția va fi prevăzută cu toate facilitățile necesare derulării de activități industriale, toate spațiile sale aferente acestora fiind la presiune atmosferică.The multi-storey industrial construction will consist of a prefabricated structure (pillars, beams, floors) of metal, enclosed in a cylindrical, ellipsoidal or ovoid housing made of rigid reinforced concrete, to withstand the pressure of the liquid column of the environment. Reinforced concrete is the optimal protection option at a competitive price of the construction against the aggressiveness of environmental waters. The construction will be provided with all the necessary facilities for carrying out industrial activities, all its spaces related to them being at atmospheric pressure.

Construcția industrială multietajată va pluti la cota stabilită, fiind ancorată cu mai multe ancore sau va fi scufundată pe fundul lacului sau mării. De aceea, ea va avea toate dotările unei ambarcațiuni neautonome, inclusiv pentru ancorare și amarare, cerute de actele normative.The multi-storey industrial construction will float at the established level, being anchored with several anchors or will be sunk on the bottom of the lake or the sea. Therefore, it will have all the equipment of a non-autonomous boat, including for anchoring and mooring, required by the normative acts.

Procedeul de execuție a construcțiilor industriale multietajată imersată în lacuri terestre sau în ape marineThe process of execution of multi-storey industrial constructions immersed in terrestrial lakes or in marine waters

Construcția se va realiza într-un șantier naval, în două etape:The construction will be carried out in a shipyard, in two stages:

- în prima etapă se va lucra într-un doc uscat până la atingerea înălțimii maxime permise de dotările acestuia. O variantă de realizare a carcasei de beton cu armătură rigidă este folosirea de cofraje glisante încălzite, care ar permite avansarea cu 4-6 m pe zi a clădirii. Construcția va fi complet echipată, cu toate instalațiile și dotările aferente, inclusiv pentru lifturile de marfă și de persoane. Radierul, notat cu 1, va fi dimensionat pentru a asigura flotabilitatea construcției la părăsirea docului uscat.- in the first stage, work in a dry dock until the maximum height allowed by its endowments is reached. A variant of making the concrete frame with rigid reinforcement is the use of heated sliding formwork, which would allow the building to advance by 4-6 m per day. The construction will be fully equipped, with all the installations and related equipment, including for freight and passenger elevators. The screed, marked with 1, will be dimensioned to ensure the buoyancy of the construction when leaving the dry dock.

- în etapa a doua, după inundarea docului, construcția se va remorca într-o incintă flotantă, fixată cu mai multe ancore, amenajată astfel încât să permită finalizarea construcției și transportul ei în siguranță pe amplasamentul dorit.- in the second stage, after the flooding of the dock, the construction will be towed in a floating enclosure, fixed with several anchors, arranged so as to allow the completion of the construction and its safe transport on the desired location.

Peste laturile longitudinale ale incintei se montează căi de rulare pentru macarale portal cu consolă. Date fiind condițiile de lucru, în permanență se va urmări încărcarea simetrică a construcției pentru a nu-i afecta flotabilitatea, ceea ce impune folosirea a două macarale portalRunways for cantilever gantry cranes are mounted over the longitudinal sides of the enclosure. Given the working conditions, the symmetrical loading of the construction will be constantly monitored in order not to affect its buoyancy, which requires the use of two portal cranes.

Stâlpii de margine, notați cu 32 - 35 în fig. 6, vor fi țevi cilindrice închise la ambele capete, cu diametre de peste 1,4 m, cu înălțimi peste nivelul căii de rulare a macaralelor peste nivelul căii de rulare a macaralelor mai mari de 2 m, cu uși de vizitare la acest nivel. Ei vor închide cele două flotoare, 30 si 31, unul dintre cilindri fiind casă a scării și celălalt fiind folosit pentru ridicare-coborâre componente ale instalațiilor din spațiul tehnic aferent camerelor de echilibru.Edge pillars, marked with 32 - 35 in fig. 6, there will be closed cylindrical pipes at both ends, with diameters over 1.4 m, with heights above the level of the crane track above the level of the crane track higher than 2 m, with access doors at this level. They will close the two floats, 30 and 31, one of the cylinders being the stairwell and the other being used for raising-lowering components of the installations in the technical space related to the balance chambers.

Pe stâlpii cilindrici se vor monta cremaliere pe care, prin sisteme cunoscute, vor rula, acționate electromecanic, grinzi metalice transversale, notate cu 36 în fig. 6, câte una pe fiecare latură. De aceste grinzi se vor fixa panouri din beton armat, notate cu 37 în fig. 6, ce vor avea rolul de contragreutăți. Prin mișcări ascendente-descendente, aceste grinzi vor menține pe orizontală incinta atât la funcționarea macaralelor cât și la eventuale contacte cu clădirea în asamblare, fiind acționate computerizat, folosinduse senzori de mișcare și de poziție.On the cylindrical pillars will be mounted racks on which, through known systems, will run, electromechanically operated, transverse metal beams, marked with 36 in fig. 6, one on each side. Reinforced concrete panels will be fixed to these beams, marked with 37 in fig. 6, which will have the role of counterweights. Through upward-downward movements, these beams will maintain the enclosure horizontally both during the operation of the cranes and at possible contacts with the building in the assembly, being computer-operated, using motion and position sensors.

Incinta pentru etapa a doua de realizare, va fi descompusă în părți componente, ce vor fi asamblate apoi la locația stabilită și, în final, se va proceda la ancorarea acesteia. Construcția industrială multietajată trasă de remorcher va fi adusă în incinta menționată și amarată de stâlpii structurii, după care se va închide și a patra latură a incintei. Pe toți stâlpii incintei se vor monta baloane umplute cu iarbă de mare, de lungimi care să acopere partea neudată a stâlpilor și câțiva metri din partea udată. Apoi, construcția industrială multietajată va fi dezlegată de la stâlpii incintei, plutind liber în interiorul acesteia. Amararea construcției multietajate se va repeta ori de câte ori se întrerup temporar lucrările de execuție a acesteia.The enclosure for the second stage of realization will be decomposed into component parts, which will then be assembled at the established location and, finally, it will be anchored. The multi-storey industrial construction pulled by the tugboat will be brought to the mentioned enclosure and moored by the pillars of the structure, after which the fourth side of the enclosure will be closed. Balloons filled with sea grass, of lengths covering the non-wet part of the pillars and a few meters from the watered part, will be mounted on all the pillars of the enclosure. Then, the multi-storey industrial building will be detached from the pillars of the enclosure, floating freely inside it. The mooring of the multi-storey building will be repeated whenever the works for its execution are temporarily interrupted.

Pentru continuarea construcției, ținând cont de cantitățile mari de betoane ce trebuie turnate continuu pe perimetrul construcției se vor folosi două nave echipate cu malaxoare de producere a betonului și cu pompe de beton cu brațe de lungime mare, în timpul montării armăturilor rigide și turnării betonului, folosind macaralele portal cu console, se vor aduce la locul de montare și monta piesele construcțiilor metalice din interior, astfel ca ridicarea structurii din beton să fie neîntreruptă.For the continuation of construction, taking into account the large quantities of concrete to be poured continuously on the perimeter of the construction, two ships equipped with concrete mixers and concrete pumps with long arms will be used during the installation of rigid reinforcement and concrete pouring, using the portal cranes with brackets, the parts of the metal constructions inside will be brought to the installation site and mounted, so that the lifting of the concrete structure will be uninterrupted.

După finalizarea construcției, se deschide incinta de asamblare și construcția va fi remorcată până la amplasamentul dorit, unde fie va fi ancorată, fie va fi scufundată pe fundul apei.After completion of the construction, the assembly enclosure is opened and the construction will be towed to the desired location, where it will either be anchored or submerged on the bottom of the water.
