The collapsible property of collapsible loess foundation brings different degrees of harm to building structure and square foundation, and large-amplitude settlement, cracking and inclination easily occur, which seriously affects the safety and use of the collapsible loess foundation. The collapsible loess foundation needs to be treated, so that the water permeability and compressibility of the loess foundation are reduced, the collapsible property of the loess foundation is controlled, and the collapsible property is partially or completely eliminated.
As a mature grouting process, the sleeve valve pipe grouting technology is widely applied to projects such as foundation pit curtains, foundations, dam region reinforcement and the like. The sleeve valve type grouting pipe is arranged in the stratum through a drill hole in the grouting process of the sleeve valve type grouting pipe, so that the grout can uniformly enter the stratum under the pressure condition. However, the diffusion range of the grout in the sleeve valve tube grouting technology is difficult to control, and the situations of grout running, grout bleeding and grout leakage are easy to occur.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a collapsible ground membrane bag slip casting control system has solved thick liquid diffusion scope when sleeve valve pipe slip casting and is difficult to control, the condition of the thick liquid of cluster thick liquid, bleeding, running easily appears.
Therefore, the utility model provides a collapsible ground membrane bag slip casting control system, including sleeve valve pipe and sack, the surface of sleeve valve pipe is provided with a plurality of injected hole, and the sack cover is on sleeve valve pipe, and sleeve valve pipe is placed in the drilling on ground with the sack is whole, and the sack intussuseption of sleeve valve pipe outside is filled with the cover shell material, and the tip of sack is tied up on sleeve valve pipe through binding apparatus, is provided with a plurality of overflow valve along sleeve valve pipe's radial on the sack.
Furthermore, the overflow valve corresponds to the grouting hole on the surface of the sleeve valve pipe.
Further, the cloth bag is a high-strength textile geotechnical model bag.
Further, the inner radius of the cloth bag is 1.3 times larger than the outer diameter of the sleeve valve pipe.
Furthermore, a plastic drainage plate is fixedly arranged on the outer side of the cloth bag.
Further, the bundling device is a thin iron wire.
The utility model provides a collapsible ground membrane bag slip casting control system, including sleeve valve pipe and sack, the surface of sleeve valve pipe is provided with a plurality of injected hole, and the sack cover is on sleeve valve pipe, and sleeve valve pipe is whole to be placed in the drilling on ground with the sack, and the sack intussuseption of sleeve valve pipe outside is filled with the cover shell material, and the tip of sack is tied up on sleeve valve pipe through binding apparatus, follows the radial a plurality of overflow valve that is provided with of sleeve valve pipe on the sack. When grouting is carried out, casing materials are poured into the cloth bag, the cloth bag is tied up on the sleeve valve pipe by using an iron wire after the casing materials flow out of the hole of the drill hole, then the casing materials are continuously poured until the casing materials are full of the cloth bag, and the pressure of the casing materials in the cloth bag is not enough to flush the overflow valve. When the slurry is injected through the sleeve valve pipe, the slurry crushes the sleeve shell material under the action of high pressure and diffuses from the overflow valve into the stratum. The sleeve valve pipe can perform layered grouting by utilizing a plurality of overflow valves arranged on the cloth bag along the radial direction of the sleeve valve pipe.
The utility model provides a pair of collapsible ground membrane bag slip casting control system, the diffusion scope of thick liquid when effective control sleeve valve pipe slip casting eliminates cluster thick liquid, emits thick liquid, runs the condition of thick liquid.
