Method for substituting pre-embedded waterproof casing pipe in concrete structure

Abstract

The invention relates to a method for substituting a pre-embedded waterproof casing pipe in a concrete structure. During the civil engineering construction stage, a square hole or a circular hole which is larger than the diameter of the casing pipe is reserved on the position of a pipeline, at the pipeline installation stage and the hole closing stage, corresponding waterproof sealing technical measures are adopted, so not only the pipeline can be embedded, but also the waterproof and the penetration prevention requirement can be satisfied. The weakness that the construction period is put off because the casing pipe and the pipeline cannot arrive in time and the method has the advantages that the time can be saved, the trouble can be saved, and the materials can be saved. The civil engineering construction is unnecessary to wait for the purchasing of the casing pipe, and the problems such as opening is independently reserved, the pipeline is independently embedded, the opening is secondarily poured and sealed, cold seam is formed in the water pond, and the water leakage future trouble is remained can be effectively solved.

Description

technical field [0001] The invention relates to a method for waterproofing construction pipelines, in particular to a method for replacing pre-embedded waterproof casings in concrete structures. Background technique [0002] With the development of construction projects, a large number of underground concrete buildings or structures that need buried pipes on the side walls will be encountered. The usual practice is to pre-embed a waterproof casing in the construction of the concrete structure before the installation project starts, but the casing generally needs to be ordered and delivered together with the pipeline. The actual situation is often in the construction stage of the concrete structure. The casing has not yet arrived, which affects the construction period. This problem is especially prominent in foreign projects and some projects that are under deadline. Another situation is that the technical profession needs to change the pipe diameter or pipe material. In th...

Problems solved by technology

Another situation is that the technical profession needs to change the pipe diameter or pipe material. In these cases, it is very inconvenient to pre-embed the casing in advance.

For the situations often encountered in the project that need to add pipelines or omit pipelines, it is even more impossible to add waterproof casings with pre-embedded methods.
