Problems solved by technology

[0003] In the related technology, the pile body needs to be grouted. In this technology, the curable grout is injected into the coating around the pile through the grouting pipe pre-buried in the pile body. Consolidation of slurry and soil is formed within a certain range around the pile, thereby strengthening the physical properties of the soil near the pile and increasing the resistance around the pile to varying degrees. However, the current consolidation can only be in a limited range of soil layers around the pile. Formation, the bearing capacity of the pipe pile is determined by the area of ​​concrete or consolidated body in its cross-sectional area
[0004] In view of the above-mentioned related technologies, the inventor believes that the grout is directly injected into the soil layer around the pile through the grouting pipe of the pile body, and consolidated with the soil layer around the pile. Due to the limitation of grouting, the area of ​​the consolidated body is small. Thereby affecting the bearing capacity and stability of the pile body

Embodiment 1

[0068] The implementation principle of Embodiment 1 is: the staff sucks out the excess water in the soft soil through the water outlet 524, and then injects the slurry through the pouring port 523, so that the slurry passes through the first pipeline 521, the pouring pipeline and the first orifice 4221 once into the In the soft ground, after the pouring is completed, pull the pull rope 426 to move the movable end 422 close to the pipe pile 1, and perform grouting again, so as to realize grouting in a wide range and increase the area of ​​the consolidated body.

Embodiment 2

[0070] refer to Figure 4 and Figure 5 , the soft soil foundation reinforcement construction method includes the following steps.

[0071] S1: Assembly:

[0072] S11: installing the reinforcement 5 on the pile point 2;

[0073] S12: Install the conveying part 4 on the support frame 21, and connect the pouring port 523, the first pipeline 521 and the pouring pipeline in sequence, and connect the water outlet 524, the second pipeline 522 and the water outlet pipeline in sequence;

[0074] S13: installing the steel guard plate on the top of the pile point 2;

[0075] S14: set pipe pile 1;

[0076] S2: Installation into soft soil:

[0077] S21: pressing the pipe pile 1 into a specific depth of the foundation soil layer;

[0078] S22: by twisting the force transmission assembly, the conveying member 4 is pressed down to fit the supporting frame 21 in an interference fit;

[0079] S23: Connect external equipment, connect the two output ports of the air compressor with the po...

Abstract

The invention relates to a soft soil foundation reinforcing device and a construction method thereof, and relates to the field of building construction.The soft soil foundation reinforcing device comprises a pipe pile and a pile tip, the pipe pile is further connected with a steel casing and a conveying piece, and a reinforcing piece used for improving the stability of the pipe pile is arranged in the pipe pile; the reinforcing part comprises a base abutting against the pile tip, a dowel bar connected to the base and a holding block, a supporting frame is fixedly connected to the pile tip, the conveying part comprises a rotating ring connected to the supporting frame and a grouting pipe rotationally connected to the rotating ring, a plurality of grooves are evenly formed in the outer wall of the rotating ring in the circumferential direction of the rotating ring, and the grouting pipe is connected to the grouting pipe. The grouting pipe is rotationally connected to the inner wall of the groove, the outer wall of the dowel bar is rotationally connected with the inner wall of the rotating ring, and a pouring pipeline communicating with the first pipeline and a water outlet pipeline communicating with the second pipeline are arranged in the grouting pipe. The pile has the effect of improving the bearing capacity and stability of the pile body.

Description

technical field [0001] The field of building construction involved in this application, in particular, relates to a soft ground reinforcement device and a construction method thereof. Background technique [0002] Concrete pipe piles are often used for soft soil foundation reinforcement of bridges, roads, and water conservancy housing construction projects. According to the different force conditions of the pile foundation in the soil, the pile foundation can be divided into end-bearing piles and friction piles according to the different force conditions in the soil. . The end-bearing pile is a kind of pile that passes through the weak coating to reach the deep solid soil. The load of the upper structure is mainly borne by the resistance of the pile tip; the friction pile is a kind of pile that is completely set at a certain depth in the weak soil layer, and the load of the upper structure must be It is jointly borne by the resistance of the pile tip and the friction betwee...
