In construction engineering, rubber waterstop is a very important accessory. Its main function is to prevent water leakage at the joints of the building structure, so as to ensure the safety and service life of the building. First of all, the rubber waterstop is made of special rubber materials, with very good elasticity and tensile properties. When it is used at the joint in the project, it can effectively absorb the stress from the outside and prevent the water seepage at the joint. Secondly, the design of rubber waterstop enables it to adapt to different construction environments. It can be customized into different shapes and specifications to meet different engineering needs. Whether it's the basement

In recent years, the requirements of rubber bearings for bridge construction are very strict, and the quality of bridge engineering is strictly required. High quality bridge engineering needs high-quality bridge bearings. In 1990, the Highway Planning and Design Institute of the Ministry of Communications entrusted the Scientific Research Institute of the Ministry of * * * to conduct a comprehensive and systematic experimental study on the manufacture of more than 100 circular plate rubbers. While producing rectangular plate type rubber bearings abroad, circular plate type rubber bearings are also produced. Their bearing capacity can reach 12MN, and some of them are listed in the standard. With the construction of high-grade highways in China, curved bridges and oblique bridges continue to appear, so it is also necessary to have circular plate rubber bearings suitable for such bridges

The expansion joint adhesive strip is a kind of sealing material for building expansion joints. It has many functions such as waterproof, dustproof, heat insulation, sound absorption, etc., and can ensure the structural stability and safety of buildings. When using expansion joint adhesive strip, it is necessary to select appropriate materials and specifications, and construct in accordance with relevant specifications. 1、 Function of expansion joint adhesive strip The expansion joint adhesive strip is a sealing material used for building expansion joints. Its main functions are: 1. Waterproofing: the expansion joint adhesive strip can play a waterproof role, effectively preventing water from soaking into the building interior. 2. Dust prevention: expansion joint adhesive strip can also prevent dust, sand and other fine particles from entering

Pot rubber bearing is a commonly used bridge bearing, which has the following main functions: 1. Shock absorption and noise reduction: pot rubber bearing can absorb and disperse the vibration of the bridge in operation, reduce the noise pollution of the bridge to the surrounding environment, and reduce the damage to the bridge structure. 2. Strong adaptability: pot type rubber bearing can adapt to the deformation and change of the bridge, avoid the cracks caused by the deformation of the bridge, and also avoid the damage to the entire bridge structure when the bridge slides. 3. Strong bearing performance: pot type rubber bearing can bear a large amount of load to ensure the safety of bridge structure. Advantages of pot type rubber bearing

Bridge expansion joint: the structure requires free expansion in both directions parallel to and perpendicular to the bridge axis; Firm and reliable; Vehicles shall pass smoothly without sudden jump and noise; Waterproof and prevent sundries from penetrating and blocking; Installation, expansion joints, inspection, maintenance and dirt removal shall be simple and convenient. It can be seen that the opinions of experts and scholars in the field of highway and bridge construction, maintenance and management are in the minority. It is believed that GQF-E type bridge expansion and contraction installation, and professionals said that cracks often appear on the surface pavement. In the view of low value consumables, it is possible to be thrown out as a whole under the condition of large longitudinal slope

The circular hole in the middle of the buried rubber waterstop is generally at the settlement joint of the building body when installing the waterstop, and the joint of the settlement joint is the place where the building body will have a "deformation" distance when settlement occurs; From this point of view, if the waterstop is a "flat single-layer surface", the "deformation resistance and elongation" of rubber of the same material is not as good as that of a circular cross section (because the circular one also has a length difference of radian that can be extended from "semicircle to diameter"); In addition, the circular cross section is double-layer on the section of the settlement joint, which is one more layer than the "flat" one, and can prevent the "good layer damage" and still maintain the water stop

Butterfly rubber waterstop is a new type of rubber waterstop for construction joints, deformation joints and other engineering joints between tunnels and underground works. Butterfly rubber waterstop has four butterfly wings, the length of which can be flexibly adjusted as required. There are several waterstop ribs on the wings, and the middle rib is between the upper and lower wings. Butterfly rubber waterstop is a kind of rubber waterstop, which is characterized by novel design, good waterproof and waterstop performance, and affordable price. Butterfly waterstop uses the high elasticity of rubber to produce elastic deformation under various loads, so as to play a firm seal, prevent water leakage and seepage of building structures, and play a shock absorption and buffer role. This product is mainly used for setting
