Background
The foundation refers to the portion of the soil body that is subjected to the load of the superstructure. The treatment of the foundation is very important in architecture, the foundation of the building is not good enough, and the superstructure is likely to collapse. The foundation can be consolidated by many methods, such as rolling compaction, dynamic compaction and bagged sand wells. The bagged sand well has the advantages of simple construction, low manufacturing cost and the like.
The prior bagged sand well is shown in figure 7 and comprises a sand well 2 arranged in a foundation 1 and a sand bag 3 vertically arranged in the sand well 2, wherein the sand bag 3 is filled with sand; the upper end part of the sand bag 3 extends out of the sand well 2. When the sand bag 3 is installed in the sand well 2, the sand bag 3 filled with sand is a vertical channel through which free moisture in the sludge permeates and rises to the ground 11, and the soil in the foundation 1 is consolidated after the water in the foundation 1 is continuously discharged, so that the foundation 1 is firmer.
In view of the above-mentioned related technologies, the inventor believes that after the reinforcement treatment of the foundation 1, the sand bag 3 is left in the foundation 1 for about ten meters, so that the difficulty of pulling out the sand bag 3 from the sand well 2 is relatively large. If the sand bags 3 are left in the foundation 1, the drainage consolidation can be continued, and the situation of post-construction settlement exists.

s6, after the guide pipe is connected with the precast pile head, the guide pipe is driven into the foundation (1) through a pile driver, and the guide pipe in the foundation (1) forms a sand well (2) after reaching the designed depth;
s7, placing one end, provided with the cutter (6), of the sand bag (3) into a guide pipe, slowly feeding the sand bag (3) into the guide pipe, slowly pulling out the guide pipe, installing the sand bag (3) in the sand well (2) to be attached to the inner wall of the sand well (2) to form a vertical drainage channel, and enabling the part, bound with the hose (4), of the sand bag (3) to exceed the ground (11);
s8, after the foundation (1) is reinforced, firstly, the pull ring (8) slides out of the hose (4) and pulls the pull rope (5) upwards, the pull rope (5) drives the cutter (6) to move upwards and cut the rope (31), and a notch is formed in one end of the sand bag (3);
s9, when the thread rope (31) is cut, pulling out the hose (4) partially, when the mounting cylinder (7) is separated from the hose (4), releasing the notch of the sand bag (3), pulling the hose (4) and the pull rope (5) out of the sand bag (3) together, and pulling out the cutter (6);
s10, after the hose (4) leaves the sand bag (3), the sand-stone containing space in the sand bag (3) is enlarged, so that the sand-stone is in a loose state, and then the sand bag (3) is pulled out from the sand well (2).
