Description

Technical Field

[0001] The invention belongs to the technical field of reconstruction of sewage and water treatment plants, and particularly relates to a water-stop structure for connecting a vertical wall plate of a prefabricated pool with a foundation and a connection construction method. Background Art

[0002] During the reconstruction of sewage treatment plants and water treatment plants, in order to save construction time and reduce carbon emissions, prefabricated components can be used for the vertical wall panels of the water pool. In the connection between the prefabricated wall panels and the cast-in-place base plate foundation, in order to ensure the integrity of the prefabricated components and the base plate, the connection requires special treatment, especially waterproofing of the connection. The connection between the prefabricated components and the base plate is usually carried out by overlapping the steel bars between the two, and then pouring high-strength grade cast-in-place concrete. This connection method has certain disadvantages for the water pool structure. One is that there is a cold joint between the new and old concrete. Long-term high water level operation of the water pool will cause water leakage in the cold joint; the second is that the cold joint leaks and cracks, the steel bars are exposed, and then corroded, which affects the safety and durability of the wall panels. Summary of the invention

A water-stopping steel plate and a water-swelling water-stopping glue are provided at the connection position between the foundation concrete part and the cast-in-place concrete part. The lower end of the water-stopping steel plate is inserted into the foundation concrete part, and the upper end of the water-stopping steel plate is inserted into the cast-in-place concrete part.

[0006] For example, the prefabricated vertical wall panel of the water pool is connected to the foundation water-stopping structure, wherein the top surface of the foundation concrete member has a concave surface, a water-stopping adhesive placement opening is provided in the concave surface, and the water-swelling water-stopping adhesive is placed in the water-stopping adhesive placement opening.

[0007] For example, the vertical wall panels of the prefabricated water pool are connected to the foundation water-stopping structure, wherein the longitudinal cross-section of the water-stopping steel plate is arc-shaped, and the water-stopping adhesive placement port is located on the convex side of the water-stopping steel plate.

[0008] In addition, a construction method for connecting the vertical wall panels of a prefabricated water pool to a foundation is provided, wherein the method is based on the water-stopping structure for connecting the vertical wall panels of a prefabricated water pool to a foundation as described above, and includes:

[0009] S1. Fix the position of the water stop steel plate in the foundation;

[0010] S2, pouring foundation concrete to form foundation concrete parts;
