Problems solved by technology

The embedded waterstop is to pour the waterstop directly into the concrete. Once damaged, it is not easy to replace, and the concrete near the waterstop is not easy to vibrate, which directly affects the waterstop effect

Embodiment Construction

[0026] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0027] In projects like the Shahe U-shaped aqueduct, the water-stop structure is very important to the aqueduct body. If water leaks during the normal water delivery period, it will not only affect the overall project appearance, but also may freeze in winter. . The Shahe U-shaped aqueduct was originally designed as a pressure plate water stop, and there is a putty material under the water stop. The water stop is pressed to the concrete surface with bolts to achieve the water stop effect. When the water-stop test was carried out in the later stage, the effect was not ideal, and there were more or less water leakage or water seepage at the water-stop joints. After several water-stop tests, it was found that the reasons for water leakage or seepage are as follows:

[0028] 1) The concrete surface of the waterstop is uneven. Although there is putty mater...

Abstract

The invention discloses a concrete joint water stop structure, and belongs to the field of waterproof technologies of concrete buildings. The water stop structure comprises pre-buried anchor holes, adhesives, rubber waterstop, a section steel pressing plate, bolts and a sealing structure; wherein the pre-buried anchor holes are preburied in a concrete structure, the rubber waterstop adheres to the surface of a concrete joint water stop channel through the adhesives, the section steel pressing plate adheres to the upper surface of the rubber waterstop through the adhesives, the bolts penetrates through the section steel pressing plate and the rubber waterstop and are fastened with the pre-buried anchor holes, and the sealing structure is arranged between the rubber waterstop and the concrete joint water stop channel. The invention further discloses a construction method of the concrete joint water stop structure. Compared with the prior art, the concrete joint water stop structure has the advantages of being simple in construction, good in water stop effect and the like.

Description

technical field [0001] The invention relates to a concrete joint waterproof structure and a construction method thereof, belonging to the technical field of concrete construction waterproofing. Background technique [0002] The hydraulic concrete buildings between the aqueduct and the entrance and exit buildings, between the tank bodies of each section, and between the concrete face rockfill dam face plates generally need to be separated by expansion joints. The expansion joints must be made of materials that can adapt to deformation and prevent water leakage. If the seam seal is not tight and reliable, it will not only cause a lot of water leakage, but also affect the safety of hydraulic structures. There are many types of joint waterproofing, which can be divided into two types: lap joint type and caulking butt joint type according to the combination form of waterproof material and concrete material at the joint. The caulking butt joint type is to embed water-stop materia...
