Abstract
The utility model relates to a cement blending anchor tube pile which comprises a hollow steel tube, wherein the front end of the steel tube is provided with a drill bit. A group of spiral slices distributed at intervals is arranged on the tube wall of the steel tube. An interval for holding cement slurry is reserved between the adjacent spiral slices. A group of slurry injecting small holes is arranged on the tube wall between the adjacent spiral slices. The utility model has the advantages of low manufacturing cost, simple and convenient construction technology, and good length, the diameter of a pile, and anti-pulling uniform power. The utility model is suitable for strata, such as mud soil, mud silty soil, clay soil, silty soil, yellow soil, sandy soil, etc.
Description
Technical field
The utility model relates to the equipment of a kind of soil excavation and stability of slope, and especially a kind of cement that is used for bracing of foundation pit and slope reinforcement stirs the anchor tube stake.
Background technology
At present, soil body plate brad supporting, bolt support are extensive use of in bracing of foundation pit engineering and stability of slope engineering.Plate brad supporting has pore-forming nail and is driven into nail, and job practices commonly used is first boring, after insert nail, slip casting again; Being driven into nail is that nail is driven into grouting behind shaft or drift lining earlier, or the limit is driven into the nail marginal not and starches and to carry out synchronously.Soil anchor supporting, job practices commonly used are first boring, after insert metal material, slip casting again.Wherein, the plate brad supporting cost is low, easy construction, but the length of soil nailing is less with the stake diameter, the equal power of resistance to plucking is little, often can not meet design requirement.The length of anchor pole and stake diameter and the equal power of resistance to plucking are greater than soil nailing, but its cost height, and construction needs two procedures, can not once finish.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, but provides the low cement of the big cost of the equal power of a kind of resistance to plucking to stir the anchor tube stake.
The utility model solves the technical scheme that its technical problem adopts: this cement stirs the anchor tube stake, comprises hollow steel pipe, and this steel pipe front end has drill bit, is intervally distributed with one group of flight on the tube wall of steel pipe; Leave the interval that holds cement paste between adjacent flight, have one group of slip casting aperture on the tube wall between adjacent flight.
The effect that the utility model is useful is: cost is low, and construction technology is easy, and its length and stake diameter and the equal power of resistance to plucking are better; Be applicable to stratum such as silt soil, mucky silt, cohesive soil, silt, loess and sand.
Description of drawings
Fig. 1 is the utility model master TV structure schematic diagram;
Fig. 2 is the utility model left side TV structure schematic diagram;
Fig. 3 is the utility model application principle figure.
Among the figure: steel pipe 1, aperture 2, flight 3, drill bit 4, cement stirs anchor tube stake 5;
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
This cement stirs the anchor tube stake, comprises hollow steel pipe 1, and this steel pipe 1 front end has drill bit 4, is intervally distributed with one group of flight 3 on the tube wall of steel pipe 1; 3 of adjacent flights leave the interval that holds cement paste, have one group of slip casting aperture 2 on the tube wall that adjacent flight is 3.
The utility model further improves on soil nailing and anchor rod construction process, 1 leading portion 1m place gets out a plurality of apertures 2 with steel pipe 1 at the slip casting steel pipe, injection slurry can be by aperture 2 ejections, at the two ends of 2 sections of steel pipe apertures welding flight 3, use lightweight drilling equipment such as electric hydaulic motor, spiral steel pipe 1 is pierced soil layer, and slip casting is simultaneously stirred and is formed the anchor tube stake.During construction, its construction technology process is: drilling equipment is in place → anchor tube mating holes position → stir system cement grout → anchor tube to pierce the soil layer → injection cement grout → helical stir soil body → welding spiral steel pipe → repeat to stir the soil body → formation to stir the anchor tube stake.The stake diameter of section is 150～250mm.As shown in Figure 3, during construction, on the slight slope face, spiral steel pipe 1 is pierced, get final product.
Cement stirs the anchor tube stake, between plate brad supporting and bolt support between the two.When plate brad supporting can not meet design requirement,, can adopt this moment cement to stir anchor tube stake 5 if adopt bolt support then its cost height.The length of cement stirring anchor tube stake 5 and stake diameter and the equal power of resistance to plucking are similar to anchor pole greater than soil nailing, once finish in the construction, have increased uplift resistance.It is easy that cement stirs the anchor tube pile driving construction, is used to keep off the soil matrix pit enclosure and slope soil stabilization works cost is low.
In order to increase the uplift resistance of soil nailing, strengthen the length and the diameter of soil nailing, make full use of the cross section of anchor tube stake, can not once finish when substituting soil nailing and anchor bolt construction, reach final effect.Stir the force analysis of anchor tube stake according to cement, the utility model provides the stake of a kind of stirring anchor tube, according to the geological conditions of soil layer, makes full use of the anchor tube stake, is satisfied with the requirement of bracing of foundation pit and slope reinforcement.Under the situation that guarantees that bracing of foundation pit and slope reinforcement engineering construction are smooth, safe, finishes on schedule, reduce cost and construction costs.
