Pot type rubber bearings are suitable for supporting beam bridges, arch bridges, low pier projects, pavement, short tunnels and other building structures. In bridge engineering, the pot rubber bearing can effectively reduce the vibration of the bridge body and improve the bearing capacity and service life of the bridge. In low pier engineering, the pot rubber bearing can reduce the stress deformation of the pier and improve the overall stability of the project; In pavement engineering, pot rubber bearing can reduce the noise and vibration generated by the pavement and improve the service life of the pavement. In general, pot type rubber bearings are not only suitable for bridge engineering, but also can be used for bearings of other building structures, such as engine base, pump foundation, etc

Rubber waterstop is a common rubber waterproof material in engineering, also known as rubber waterstop and rubber waterstop. It is made of natural rubber or EPDM as raw materials, added with various accelerator materials and various filler materials, mixed in an internal mixer to form raw films, and then vulcanized and molded by a vulcanizing machine. The rubber waterstops of various models or sizes are produced by pressing various abrasive tools, and the width, thickness and shape of these abrasive tools are derived from the data required by the design drawings in the project, of which the steel edge type and buried type are common models of waterstops. Performance and function of rubber waterstop Since rubber waterstop is based on rubber

Bridge expansion joint: it refers to the expansion joint usually set between two beam ends, between beam ends and abutments, or at the hinge position of the bridge to meet the requirements of bridge deck deformation. It is required that the expansion joint shall be able to expand freely, firmly and reliably in both directions parallel to and perpendicular to the bridge axis, and shall be smooth without sudden jump and noise after the vehicle is driven; Prevent rainwater and garbage from infiltrating and blocking; Installation, inspection, maintenance and dirt removal shall be simple and convenient. At the place where expansion joints are set, the railing shall be disconnected from the deck pavement. The function of the bridge expansion joint is to adjust the displacement between the superstructure caused by the vehicle load and the bridge building materials and

In the construction field, waterstop is an important waterproof material, which can effectively prevent water infiltration and erosion. Among them, the steel edge rubber waterstop is widely used because of its excellent performance and durability. This paper will discuss several common styles of steel edged rubber waterstop. The steel edge rubber waterstop is mainly composed of steel strip and rubber. The steel strip serves as a skeleton to provide strength and support, while the rubber part provides elasticity and sealing performance. According to the structure and design characteristics, the steel edge rubber waterstop is mainly divided into the following types: 1. Straight waterstop: straight waterstop is the most common type, which consists of a straight steel

The L-600 polyethylene closed cell foam board is a L-600 plate with a foaming rate of medium and high pressure. The appearance is pure black, the surface is rough, and obvious pores can be seen. The diameter of pores is about 0.5mm. The texture is very hard, like a wood board, but the toughness is not as good as that of the medium pressure closed cell board. The compressive strength and tensile strength are very high, reaching the medium high level of the foam board. With a large proportion, each square weighs about 160kg. Due to its performance and cost, high-pressure polyethylene closed pore plate is mainly used in high-speed railway, airport, panel dam and other large-scale hydropower transportation projects. General name of polyethylene closed cell foam board: polyethylene closed cell foam plastic board, P
