What is the meaning of the CB type and CP type of the buried rubber water stop?
1. Classification of buried waterstops
From the structural form, it can be divided into two types: CB type waterstop and CP type waterstop. The commonly used 651, 652, and 653 waterstops are all CB rubber waterstops. According to the two types of waterstops, their scope of application is explained separately, and they are slightly different.
The type of waterstop is a medium-sized waterstop with a hole in the middle. It can be divided into CB rubber waterstop and CB plastic waterstop. It is mainly used for expansion joints, settlement joints and various concrete structures. Anti-seismic joints, etc., have the ability to anchor tightly with concrete, seal the water seal and adapt to the deformation and deformation of the deformation joint. CP type water stop belt refers to the middle non-porous buried water stop belt, which can be divided into CP type rubber waterstop. , CP type plastic waterstops. It is mainly suitable for construction joints of various concrete structures with small deformation, fully shrinkage joints, incomplete shrinkage joints, expansion joints, etc., with tight anchoring with concrete, water sealing and elasticity Tensile deformation and other characteristics. .
Second, the buried rubber water stop belt water stop principle
The function and principle of the buried rubber waterstop is to utilize the high elasticity of the rubber to produce elastic deformation under various loads, thereby achieving a firm seal, effectively preventing leakage of the building structure, seeping water and damping shock. In many engineering and architectural design, civil engineering, soil and water structure have certain expansion and contraction requirements, and there are problems such as waterproof and shockproof. Therefore, the use and installation of rubber waterstops is a means to effectively solve the above problems. This product is mainly used for When the concrete is poured, it is placed in the construction joint and deformation joint, and the concrete structure is integrated with the concrete structure, underground facilities, tunnel culverts, water transfer aqueducts, retaining dams, etc. to ensure the service life of the project. The buried rubber waterstop Adopted the national standard GB18173.2-2000 "polymer waterproof material waterstop" organized production.
Third, the commonly used buried rubber water stop tape specification series and scope of use 
Fourth, the buried rubber water stop joint method
There are two types of buried rubber waterstop joints: one is to use a bonding agent for cold joints, and the other is to use a hot vulcanization mold for hot joining. The following two joint methods are introduced below: adhesive cold junction It is a special cold-bonding glue for rubber waterstops. The cross-section of the waterstops that need joints is smoothed by a sander by 5~10 cm, and the glue is compacted. It has the advantages of high strength and quick solidification. The construction is convenient, saves time and effort, and can meet the general engineering quality requirements. The on-site hot joint vulcanization method joint uses the hot vulcanization mold matched with the water stop belt and the raw film on-site vulcanization and heat connection. The construction is difficult, but the joint effect is ideal, suitable for Projects with strict quality requirements.
