Basement ground construction maintenance drainage structure of large building and method for constructing basement concrete layer

Abstract

The invention discloses a basement ground construction maintenance drainage structure of a large building. The basement ground construction maintenance drainage structure comprises a basement ground concrete layer, and a fine stone layer is arranged under the basement ground concrete layer; the fine stone layer is laid on the surface of an underground soil body; longitudinally or horizontally distributed gutters are downwards dug in the surface of the underground soil body; first water pumping pipes downwards penetrate through the basement ground concrete layer and stretch into the gutters; and the first water pumping pipes communicate with the exterior. According to the structure, underground water can be drained through pumping in the maintenance stage of the basement ground.

Description

[0001] Technology area [0002] The invention relates to a ground construction and maintenance drainage structure in the basement of a large building. The present invention also relates to a method for constructing a basement concrete layer by using the ground construction maintenance drainage structure of the basement of a large building. Background technique [0003] In the water-rich area, the basement floor is deep into the soil, and the concrete layer on the basement floor will be under the pressure of groundwater during pouring. During the maintenance stage, the concrete layer on the basement floor has not yet solidified, and it is easy to form cracks under the pressure of groundwater, thereby affecting the quality. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a large-scale building basement ground construction and maintenance drainage structure, which can pump and drain groundwater during the basement gro...
