Basement top plate deformation joint waterproof system and technology

Abstract

The invention relates to the technical field of underground construction waterproof protection, in particular to a basement top plate deformation joint waterproof system and technology. The basement top plate deformation joint waterproof system comprises a buried type water stop belt used for preventing external water from entering a deformation joint, a deformation joint backer plate with which the deformation joint is filled, an externally-bonded type metal plate pressure-bearing water stop belt used for sealing the deformation joint, and a waterproof structure used for preventing water for the externally-bonded type metal plate pressure-bearing water stop belt. According to the basement top plate deformation joint waterproof system, by arranging the externally-bonded type metal plate pressure-bearing water stop belt, environment water isolation treatment is carried out on a waterproof weak joint of the building underground construction top plate deformation joint, the waterproof structure is laid on the deformation joint, has the certain performance guarantee and can bear a certain environment pressure, and the effect of joint enhancement is achieved.

Description

technical field [0001] The invention relates to the technical field of underground engineering waterproof protection, in particular to a waterproof system and a waterproof process for deformation joints of a basement roof. Background technique [0002] In the investigation of underground engineering leakage water, the leakage water of the underground engineering roof mostly occurs at the roof deformation joints. The existing joint construction methods of the conventional underground engineering roof deformation joints are as follows: figure 1 shown; figure 1 Among them, 1 is the concrete structure, 2 is the joint filling material, 3 is the water stop strip, 12 is the waterproof structure, 13 is the isolation layer, and 14 is the sealing material. The design of the external waterstop requires a certain amount of support from the concrete layer or other structural layers at both ends of the waterstop. In the roof project, the waterproof measures are on the outside of the stru...

AI Technical Summary

Problems solved by technology

The design of the external waterstop requires a certain amount of support from the concrete layer or other structural layers at both ends of the waterstop. In the roof project, the waterproof measures are on the outside of the structure, which must provide support for the external waterstop. There is difficulty in the strength, which leads to the situation that although the design is reasonable, the construction operability is poor, which is not applicable to the use of waterstops.

Regardless of the construction feasibility and engineering applicability, the tight fit with the structure is not realized, and water channeling is easy to form; blindly adopting reinforcement measures on the outside of the structure means that the waterproof function can be realized, which is why the waterproof scheme design is theoretically reasonable and waterproof. The material performance is excellent, and the construction operation is standardized, but there are still serious leakages in the underground engineering

In addition, different treatment methods for different types of deformation joints in new projects basically require sufficient and dense structures or clamping forces on both sides of the waterstop to effectively ensure the waterproof effect of this part. Although the existing methods are reasonable in design, they cannot Poor construction operability, does not meet the actual needs of the project
