Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that the excavation area of ​​the foundation pit is different, and the soil on the wall of the foundation pit is also different. The moisture content of the soil in some areas is relatively high, which makes the soil on the side wall of the foundation pit looser. There will be a distance between two adjacent retaining piles, making the soil between the two retaining piles unstable and there is a risk of sliding into the foundation pit

Abstract

The application relates to a foundation pit support device and a foundation pit support method, belonging to the technical field of building foundation pits. It includes support piles arranged continuously and arranged side by side and reinforcements arranged between two adjacent support piles. The reinforcement includes at least one blocking plate. Connected; the blocking plate includes an abutting plate abutting against the side wall of the foundation pit, a waterproof plate arranged parallel to the abutting plate, and a support plate arranged between the abutting plate and the waterproof plate, the support plate The two ends are respectively connected with the abutment board and the waterproof board; the waterproof board is pasted with a film, and the support board is a honeycomb board. After the setting of the supporting piles is completed, a reinforcing piece is set between two adjacent supporting piles, and the sidewall of the foundation pit between the two adjacent supporting piles is covered by the reinforcing piece, so that the soil on the sidewall of the foundation pit in this area It is not easy to slide into the foundation pit.

Description

technical field [0001] The present application relates to the technical field of building foundation pits, in particular to a foundation pit support device and a foundation pit support method. Background technique [0002] Row pile support is one of the widely used forms of foundation pit support in China. The row pile support has the advantages of high support rigidity, small space occupation, and mature construction technology. [0003] In the related technology, the construction steps of row pile support are generally as follows: firstly, the set position of the support pile is selected according to the construction drawings, and then the continuous and side-by-side pile holes are dug out by a pile digger at the set position, and then the pile A reinforcement cage is placed in the hole, and concrete is filled in the reinforcement cage. After the concrete sets, the reinforcement cage and the concrete form support piles. Finally, the foundation pit is excavated, and part o...
