Processing method for basement water-proof concrete construction joint

Abstract

The invention discloses a treatment method of basement waterproofing concrete construction joints, comprising the following steps of: (1) construction joint arrangement: the construction joint consists of two parts which form ladder shape inside the wall, construction is carried out to the outside construction joint and a substrate together; the inside construction joint is arranged on the substrate and constructed together with the upper wall; (2) water-stopping plate arrangement: a water-stopping steel plate is vertically arranged on the outside horizontal construction joint with the wall higher than the substrate; and (3) concrete pouring: the concrete construction of the outside construction joints and the substrate is finished simultaneously; and the concrete construction of the part above the inside construction joint and the upper wall is finished simultaneously. By adopting the staged construction joint arrangement, not only the permeating path of the waterproof concrete can be increased, the impermeable capability of the waterproof concrete is effectively enhanced, and the leakage occurrence of the building is reduced, but also the construction joint left on the wall substrate guarantees the visual quality of concrete surface inside the outside wall, thus solving the problem that the basement concrete wall inside surface has poor visual quality of the construction joint.

Description

technical field [0001] The invention relates to a joint and sealing method of a hydraulic structure, in particular to a treatment method for waterproof concrete construction joints in a basement. Background technique [0002] At present, in the construction of industrial and civil buildings, most of them are inseparable from concrete, and the construction joint of cast-in-place concrete can be said to be a problem that almost every concrete project will encounter during the pouring process. The way of leaving construction joints, the quality and location of construction joints directly affect the quality and safety of the entire building structure, so the quality of construction joints must be strictly controlled. The construction joint is not a real "seam". It is only because the post-cast concrete exceeds the initial setting time, and there is a joint surface with the first-cast concrete, which is called the construction joint. Various hidden dangers and quality problems ...

AI Technical Summary

Problems solved by technology

[0005] The horizontal construction joints set up in this way have a short leakage path. If the treatment is not good, it is easy for groundwater to infiltrate from the outer wall, and obvious seam marks will be left on the basement wall, which will affect the visual quality of the concrete surface.
