Description
Technical Field
The utility model belongs to the building field, concretely relates to movement joint seepage repair structure.
Background
Waterproof of the building joint is a well-known weak link, and the waterproof of the building joint is one of the keys related to the success or failure of the whole waterproof system. The deformation joint is a part of the building which is concentrated in deformation and is dynamic. The deformation amount is large and the dynamic deformation frequency is high. The deformation joint is waterproof, and the requirements of sealing and waterproofing, deformation adaptation, convenient construction, easy maintenance and the like are met. And the connecting part is tightly connected with the whole body in a waterproof way, the form of the connecting part is complex, the construction procedures are multiple and other factors, so a structural scheme and a material which are large in adaptive dynamic deformation, fatigue resistant, underground medium corrosion resistant, simple and convenient in construction process and simple in maintenance are required to be arranged. The reason for the deformation joint leakage is as follows. The expansion and the sedimentation of the structure cause the local rupture and the pull-off of the embedded water stop (some may be damaged in the construction), cause the water leakage in the seam, and the concrete at the periphery of the embedded water stop is not compact. Grouting and plugging are only one method for temporarily stopping water, foamed polyurethane is a plastic material, and an interface can be pulled open or broken when a seam is subjected to multiple telescopic deformation or the deformation amount is too large, so that water leakage is caused again.
The common rubber water stop has the problem of lap joint, the rubber is very difficult to bond, and the water resistance of the glue is poor. The lap joint is the weak point for future water leaks. When the detachable water stop is installed, the fastening bolt can lift the screw rod upwards, so that the gap between the screw rod and the concrete is enlarged, and a new leakage point is caused. The rubber water stop belt is difficult to be matched with the base surface at the turning position, and leakage is easy to occur.
