? Neoprene rod? It is a kind of cylindrical waterstop material made of neoprene as the main raw material, mixed with various synthetic rubbers, additives and fillers, through plasticating, mixing, extrusion molding, and then vulcanized at high temperature. It has excellent properties such as aging resistance, oil resistance and abrasion resistance, and is especially suitable for seepage prevention and water stop of water conservancy projects such as concrete face dams. The design of neoprene rod takes into account the need for large joint displacement. It is usually designed as a wavy shape with large deformation capacity to ensure that when the large joint opens, it can withstand the action of high water pressure, while maintaining its supporting role to prevent being pressed into the joint. There are many specifications of neoprene rod

The two-component polysulfide sealant has the performance of self bonding with concrete, has the ability of caulking and water stop, and can contact with water 48 hours later. It is widely used in underground waterproof joints, aircraft runways, water storage facilities, sewage pools, underground projects, large water conservancy projects, etc. Features of two-component polysulfide sealant include:? Oil and solvent resistance?: As polysulfide sealant contains very strong polar "-- SS --" group, it is difficult for gas to diffuse into it, showing good gas tightness. At the same time, the existence of this group also makes polysulfide sealant not combine with oil, non-polar solvents, etc., so it has

? External rubber waterstop? It is a kind of waterstop structure used outside the concrete deformation joint and settlement joint wallboard of underground structures, also known as back stick waterstop or external waterstop. Its main function is to prevent water infiltration, and to adapt to the expansion and deformation of concrete through its material elasticity and structural form, so as to play a firm sealing role, effectively prevent water leakage and seepage of building structures, and play a shock absorption and buffer role. The width of the external rubber waterstop is generally 200-350. According to the design selection, the seepage diameter should be appropriately extended. During the concrete pouring process, part or all of the rubber waterstop should be poured into the concrete, with

? PN type water expandable waterstop? It is a unique new rubber product, which has the property of swelling when encountering water, and is mainly used for waterproof requirements. It is composed of high pressure polyurethane foam and polyester film, which has the ability to expand when encountering water. It can quickly absorb water and expand when encountering water, forming an effective water stop layer, changing the volume to fill gaps, so as to achieve the purpose of waterproof. PN type water swelling waterstop has good flexibility and plasticity, and can be cut and shaped according to different gap sizes and shapes to meet different types of engineering needs. In addition, it also has weather resistance and durability, can withstand long-term water erosion and different rings

? Medium buried rubber waterstop? It is a kind of waterstop product mainly used in concrete deformation joints, expansion joints and other concrete internal settings. It has high elasticity and compression deformation, can adapt to the expansion deformation of concrete, effectively prevent water leakage and seepage of building components, and play a shock absorption and buffer role to ensure the service life of engineering buildings. This waterstop is usually made of rubber material, which can produce elastic deformation, thus playing the role of fastening and sealing, effectively preventing water from seeping through structural gaps, and protecting the stability and durability of the structure. The middle buried rubber waterstop is not a single model, and its models are diverse, including 651

P50 water stop rubber, also known as P-type rubber water stop, is a commonly used water stop material, which is widely used in the setting of concrete deformation joints and settlement joints of underground structures outside the wall plate (upstream surface) to adapt to the expansion and deformation capacity of concrete. This waterstop takes advantage of the characteristics of rubber, such as good elasticity and compression deformation, high tear resistance and tensile strength, and the elastic deformation of the product under various loads without tearing or breaking, thus playing the role of fastening, sealing, seepage prevention and leakage prevention. The production materials of P50 type water stop rubber include natural rubber or synthetic rubber, which are mixed with a variety of raw materials after segmental refining by rubber mixing equipment

The groutable rubber waterstop is a new type of waterstop, which is improved on the basis of the traditional waterstop. By setting grouting pipes and check valves on both sides of the waterstop, the waterproof safety coefficient of the construction/expansion joint is improved.? This waterstop is designed to solve the weakness of traditional waterstop, especially in the construction process of deformation joints and construction joints of waterstop with good waterproof performance. If the construction quality is not up to standard, water can still seep from the gap between waterstop and concrete, causing water leakage. In addition, poor joint quality of waterstop is also the main reason for water leakage of construction joints.? The main part of groutable rubber waterstop

Rubber bridge expansion joint of organ type guardrail? It is an important bridge component, designed to deform with the expansion of the bridge to protect the safety and stability of the bridge structure. It is mainly composed of rubber expansion joints and steel plates. It adapts to the displacement of the beam layout through the shear deformation between the high and low grooves of the rubber expansion joints. Therefore, it is also called shear type rubber plate expansion joints. This expansion joint has a certain vertical stiffness and can bear the vehicle load. At the same time, the deformation range can reach 30 to 300 mm, ensuring the stability of the connection and the safety of driving. The design and installation of rubber bridge expansion joints of organ type guardrails need to take into account
