Deformation joint later-burying type waterstop belt and mounting method thereof

Abstract

The invention discloses a deformation joint later-burying type waterstop belt and a mounting method thereof. The belt comprises a semi-flexible semi-rigid waterstop plate which is arranged on the deformation joint of a concrete wall, the waterstop plate is located on an opening, close to the indoor side, of the deformation joint and is fixed to the concrete wall, the middle of the waterstop plateis bent to be suitable for telescopic deforming of concrete on two sides, during construction, the needed waterstop plate is determined through measuring in advance, the waterstop plate is fixed through an anchorage agent, the water leakage appearing in the connecting position of the waterstop plate and the concrete can be effectively prevented, the semi-flexible semi-rigid waterstop plate has thebetter durability relative to the traditional rubber type flexible material, the problem that the traditional rubber type flexible material has the poor durability can be solved, the waterstop platehas the certain elastic deforming capacity, and can be suitable for deforming of uneven sedimentation of the concrete wall, the waterstop plate is not prone to damage due to sedimentation stretching,when the leakage appears in the waterstop plate subsequently, repairing can be achieved directly through welding, and the aim of facilitating repair is achieved.

Description

technical field [0001] The invention relates to the field of waterproofing of deformation joints, more specifically, it relates to a water stop belt embedded behind deformation joints and an installation method thereof. Background technique [0002] Deformation joints are the general term for expansion joints, settlement joints and seismic joints. Buildings often deform under the action of external factors, leading to cracking or even destruction. Deformation joints are structural joints reserved for this situation. [0003] At present, rubber waterstops for deformation joints in domestic subways, railways, municipal pipes and other underground projects mostly have serious defects of failure. For example, the Chinese patent with the notification number CN101705696B discloses a method for preventing and controlling leakage of deformation joints in basements, using clay, Water, oil, and additives form soft plastic materials, which are poured into sealed bags to make soft plast...

[0003] At present, rubber waterstops for deformation joints in domestic subways, railways, municipal ducts and other underground projects mostly have serious defects of failure. For example, the Chinese patent with the notification number CN101705696B discloses a method for preventing and controlling leakage of deformation joints in basements, using clay, Water, oil, and additives form soft plastic materials, pour them into sealed bags to make soft plastic sausage filling strips, apply waterproof adhesive to the deformation joints and the walls where the waterstops are buried, and then fill the deformation joints with filling strips. Cover the elastic pressure strip, press the gasket nut to fix

It has the advantages of easy material acquisition, low price, and simple installation; however, it mainly uses soft filling strips to achieve waterproof purposes. On the one hand, this waterproof method has the problem of short service life, and the filling strips are prone to damage as time increases. , on the other hand, there are defects that are difficult to repair after the soft filling strip is damaged and leaks, which needs further improvement
