Waterproof protective structural concrete for large deep foundation pit

Abstract

The invention discloses waterproof protective structural concrete for a large deep foundation pit. The waterproof protective structural concrete comprises a steel nail, a special gasket, a base layer, a waterproof roll, a supporting structure, an external corner, an internal corner and structural concrete; the base layer is arranged at the outer side of the supporting structure and is fixedly connected with the supporting structure, the waterproof roll is arranged at the outer side of the base layer and internally provided with a weatherproof layer and an adhesive layer, and the weatherproof layer of the waterproof roll is fixedly connected with the base layer; the steel nail is arranged on the waterproof roll, the special gasket is arranged between the steel nail and the special gasket, and the steel nail is fixedly connected with the base layer and the supporting structure through the special gasket; the structure concrete is arranged outside the waterproof roll and is fixedly connected with the adhesive layer of the waterproof roll. As the waterproof roll is arranged, firm and continuous adhesion between the roll and the concrete can be formed after the structural concrete is cured, fluid channeling, caused by local failure of the waterproof layer, of external water between a waterproof layer and the structural concrete can be avoided.

Description

technical field [0001] The invention relates to structural concrete for large deep pits, in particular to structural concrete with waterproof protection for large deep foundation pits. Background technique [0002] In the construction industry, especially high-rise civil buildings and commercial buildings in large and medium-sized cities, they basically adopt the form of large underground garages with deep foundation pits to maximize the available space and reduce costs. However, at present, most of the underground projects in my country are Using traditional materials and traditional construction techniques to construct the waterproof layer, the defect of this method is that when the waterproof layer is damaged, groundwater will form a series between the waterproof layer and the structural concrete. The proportion of anti-adhesive waterproofing new technology used is still very low, and it has great development and application prospects in our country. Vigorously promoting th...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a structural concrete with waterproof protection for large deep foundation pits, which solves the problems that the waterproof layer is often broken and groundwater flows between the waterproof layer and the structural concrete when the traditional structural concrete is waterproofed.
