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.

Embodiment Construction
[0011] The implementation steps of the inventive method are described in detail below according to the accompanying drawings:
[0012] 1. First, when pouring concrete, leave a square hole 2 or a round hole in the place where the casing needs to be buried. The side length or hole diameter is about 30cm larger than the pipe diameter 1, such as figure 1 As shown, in this step, it is better for the structure to leave round holes, but the construction formwork is more complicated and can be selected according to needs. Regardless of whether it is a square hole or a round hole, the steel bars must be strengthened according to the requirements of the concrete specification. This step is similar to the method of reserving the casing.
[0013] 2. For particularly important parts or parts with relatively high water pressure, a steel plate water stop sheet 3 should also be buried in the middle of the pool wall where the hole is left. This step is not required for general parts, such as ...

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...
