Steel form partition assembly and construction method for construction of flexible granular waterproof protective layer

Abstract

The invention proposes a steel formwork partition assembly and a construction method for the construction of a flexible granular waterproof protective layer, which relate to the technical field of building waterproofing. The steel formwork partition assembly includes a steel formwork partition, an inner support and a limit column. The construction method includes: Place the steel form partition between the outer wall of the basement and the wall of the foundation pit, make the inner support against the outer wall of the basement, insert the limit column into the bottom of the backfill along the side wall of the steel form partition, and place it on the steel form partition Backfill the flexible granular filler between the basement wall and the basement wall, backfill the backfill soil between the steel formwork partition and the foundation pit wall, lift up the steel formwork partition and limit columns, repeatedly backfill the flexible granular filler and backfill soil, and repeatedly lift the steel formwork Partition boards and limit columns are backfilled repeatedly until a flexible particle waterproof protective layer is formed between the basement wall and the steel formwork partition, and a normal backfill layer is formed between the foundation pit wall and the steel formwork partition, which solves the problems in the basement in the prior art. , The need to install a waterproof layer protective layer before backfilling the underground garage leads to the waste of building materials and the prolongation of construction time.

Description

technical field [0001] The invention belongs to the technical field of building waterproofing, and specifically provides a steel form partition assembly and a construction method for the construction of a flexible granular waterproof protective layer. Background technique [0002] There is generally about 2 meters of space between the side wall of the basement and the support of the foundation pit, which needs to be backfilled after the construction of the basement is completed. In order to prevent water seepage and leakage in the basement, a waterproof layer is usually laid on the outer wall of the basement. Stones, sharp objects, etc., are likely to damage the waterproof layer during the backfill process, resulting in the waterproof layer not achieving a good waterproof effect. [0003] In the prior art, in order to prevent the backfill material from damaging the waterproof layer, a waterproof layer protective layer is usually installed before backfilling. At present, the ...
