Rubber waterstops are made of natural rubber and various synthetic rubbers as the main raw materials, mixed with various accelerators and fillers, and are molded through plasticizing, mixing, and pressing. There are many varieties and specifications, including bridge types. , mountain type, type, type, type, B type, type, type, type, type, etc. According to the usage, it can be classified into buried rubber waterstop and back-mounted rubber waterstop. Rubber water-stop material has good elasticity, wear resistance, aging resistance and tear resistance, strong adaptability to deformation, good waterproof performance, and a temperature range of one ℃ + ℃. It should be noted here that the rubber waterstop must not be used when the temperature exceeds the limit, and when the rubber waterstop is subject to strong oxidation or corrosion by organic solvents such as oil.
Applications of rubber waterstops
Rubber waterstops can be widely used in various types of concrete structures, such as retaining dams, reservoirs, subways, culverts, tunnels and other underground projects. In some construction projects, due to the inability to pour continuously, the deformation of the foundation, or the thermal expansion and contraction of concrete components caused by temperature changes, etc., deformation joints and construction joints are often left during pouring, and these deformation joints, Construction joints often cause structural leaks. In order to prevent leakage caused by deformation joints and construction joints, it is required to use rubber waterstops at the deformation joints or construction joints. This is because the rubber water-stop bag can not only prevent groundwater or external water from leaking into the building structure, but also prevent water inside the building from leaking to the outside world. Based on this, rubber water-stop bags are widely used in underground concrete expansion joints in sewage treatment plants, water plants, dams, hydropower stations, etc. During the construction process, rubber waterstops are pre-embedded in the deformation joints when pouring concrete and are integrated with the concrete. The plugs can effectively prevent water seepage and leakage at the deformation joints of the structure, and play a role in shock absorption and buffering. , thereby ensuring that the waterproofing requirements in engineering structures are met.
