Steel formwork partition plate assembly for construction of flexible particle waterproof protection layer and construction method

Abstract

The invention provides a steel formwork partition plate assembly for construction of a flexible particle waterproof protection layer and a construction method, and relates to the technical field of building waterproofing. The steel formwork partition plate assembly comprises a steel formwork partition plate, inner supporting parts and limiting columns. The construction method comprises the steps that the steel formwork partition plate is placed between a basement outer wall and a foundation pit wall, thus the inner supporting parts abut against the basement outer wall, the limiting columns areinserted into the bottom of the backfilling position along the side wall of the steel formwork partition plate, the space between the steel formwork partition plate and the basement outer wall is backfilled with flexible particle fillers, the space between the steel formwork partition plate and the foundation pit wall is backfilled with backfill soil, the steel formwork partition plate and the limiting columns are elevated upwards, repetitive backfilling of the flexible particle fillers and the backfill soil is conducted, the steel formwork partition plate and the limiting columns are elevated repeatedly, repetitive backfilling is conducted till the flexible particle waterproof protection layer is formed between the basement outer wall and the steel formwork partition plate, and a normalbackfilling layer is formed between the foundation pit wall and the steel formwork partition plate. The problems that in the prior art, before a basement and an underground garage are backfilled, a waterproof layer protecting layer needs to be arranged, consequently, building materials are wasted, and the construction time is prolonged are solved.

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 ...
