Grouting method for concrete raft foundation construction joint

Abstract

The invention discloses a grouting method for a concrete raft foundation construction joint. On the basis of banding reinforced concrete raft foundation lower double-layer rebar and reinforced concrete raft foundation upper double-layer rebar, vertical rebar is welded, grouting pipes are laid in a middle rabbet groove of the concrete raft foundation construction joint at horizontal spacing of 500mm according to preset requirements, when a water leakage phenomenon occurs to molded concrete in the use process, the laid grouting pipes can be used for grouting caulking, technical problems which cannot be solved by conventional waterproof treatment are solved, quality is guaranteed, the construction period is shortened, cost is reduced, and the purpose of prevention and treatment integration is realized. Compared with a traditional joint treatment method, the grouting method has the advantages that not only is material performance excellent, installation is simple and convenient, the construction period is shortened, the cost is reduced, under the premise of not damaging the structure, it is ensured that no leakage occurs at the joint, and the grouting method is an advanced and effective joint waterproof measure.

Description

technical field [0001] The invention relates to a building construction method, in particular to a grouting pipe embedding method for grouting and plugging leakage in the case of leakage at the construction joint of the concrete raft foundation. Background technique [0002] Due to human requirements for space, reinforced concrete raft foundations are getting larger and larger. During the construction process, in order to prevent uneven settlement of buildings or cracks caused by excessive concrete pouring at one time, large raft foundations are generally Divide into small pieces or set post-casting strips on the concrete raft foundation to form construction joints, and the waterproof treatment at the construction joints is particularly important. [0003] At present, the waterproof treatment of the construction joints of raft foundations adopts a preventive method, that is, a water stop is buried in the middle of the concrete raft foundation structure at the construction jo...

AI Technical Summary

Problems solved by technology

However, due to various reasons, water leakage often occurs at the construction joints. Once the construction joints of the raft foundation leak, it is difficult and time-consuming to plug the leakage.
