Operation frame body capable of canceling backfilling of basement outer wall and construction method

Abstract

The invention relates to an operation frame body capable of cancelling backfilling of a basement outer wall and a construction method. The construction method includes the steps that the operation frame body capable of cancelling backfilling of the basement outer wall is constructed firstly, then a series of construction of a basement bottom plate are conducted, and finally a thermal insulation layer and a waterproofing layer on the outer facade of a basement wall body are constructed and concrete of the outer facade of a basement and a basement floor face are poured at the inner side of the operation frame body. By adoption of the operation frame boy capable of cancelling backfilling of the basement outer wall and the construction method, the procedure of concrete backfilling in a traditional basement construction method can be canceled, meanwhile, no influence on construction of waterproof of the outer facade of the basement and other engineering can be guaranteed. By adoption of the construction method, land utilization of at least 0.3-1.2m basement perimeter can be enlarged, or earth-rock of 0.3-1.2m basement perimeter can be less excavated, so that unnecessary costs on a leveling layer, a waterproof protection layer, a brick protection wall, an external formwork, an external frame pipe, backfilling earth and the like of outdoor facades can be saved.

Description

technical field [0001] The invention relates to a construction method of a basement, in particular to an operating frame and a construction method for canceling the backfilling of the basement exterior wall. Background technique [0002] With the continuous reduction of land resources and the continuous improvement of construction technology, the height and depth of housing construction are constantly developing into the air and underground. The height of buildings is getting higher and higher, and the depth of basements is also getting deeper and deeper. [0003] Traditional basement construction methods mainly include the following steps: [0004] (1) Construction foundation pit supporting piles; [0005] (2) Excavate earth and stone, and spray concrete base between the support piles after excavation (configure steel mesh and reinforcement according to design); [0006] (3) Construction basement floor C20 concrete cushion (surface polished); [0007] (4) Construct the w...

AI Technical Summary

Problems solved by technology

[0021] It can be seen from the above that in the traditional basement construction method, the waterproof layer and the brick wall protective layer operating frame are set for the exterior facade of the basement, so as to facilitate the waterproofing and protection of the exterior facade of the basement and the work of protecting the wall. The operation frame needs to be dismantled before the earthwork backfill process can be carried out. The construction process is numerous, the cost is high, and the workload is heavy. Moreover, the operation frame is wasted, which reduces the usable area of ​​the basement.
