? 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

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

? GBZY circular plate rubber bearing is a kind of bridge bearing product, which is made of multilayer natural rubber sheets and steel sheets inlaid, bonded and vulcanized.? This kind of bearing has sufficient vertical stiffness to bear vertical load, and can reliably transmit the pressure of superstructure to the pier and abutment. At the same time, it has good elasticity and large shear deformation capacity to adapt to the rotation of the beam end and the horizontal displacement of the superstructure. The design of GBZY circular plate rubber bearing takes into account the advantages in use, such as the elastic absorption of deformation in all directions of the superstructure through the rubber, and the circular bearing surface avoids the phenomenon of stress concentration. This

Two component polysulfide sealant is generally composed of a variety of components, including polysulfide rubber, various rubber additives and fillers. The molecular weight of polysulfide rubber determines the tensile strength and good elongation of polysulfide sealant. The smaller the molecular weight of the rubber, the greater the tensile strength of the sealant, and the smaller its better elongation, which is commonly referred to as low modulus polysulfide sealant. On the contrary, the larger the molecular weight of the rubber, the lower the tensile strength of the sealant, and the greater its better elongation, which is referred to as high modulus polysulfide sealant. Rubber additives generally include plasticizer and viscosifier, plasticizer can adjust polysulfide

? Z60 bridge expansion joint? It is a high-performance expansion device specially designed for roads and bridges. It has the following features and functions:? Design points?: The design of Z60 expansion joint is aimed at meeting the requirements of bridge deck deformation, ensuring that expansion joints are set between two beam ends, between beam ends and abutments, or at the hinge position of the bridge to adjust the displacement and connection between superstructure caused by vehicle load and bridge construction materials. It requires that the expansion joint can expand and contract in two directions parallel to and perpendicular to the bridge axis, and it should be firm and reliable, to ensure that the vehicle runs smoothly, without sudden jumps and noise, and to prevent rainwater and garbage from penetrating

The outer sticking rubber waterstop is made of natural rubber and synthetic rubber as the main raw materials, which are refined, mixed and pressed to form, and has excellent properties such as aging resistance, water resistance, acid and alkali resistance, abrasion resistance, etc. The design of this waterstop takes into account the expansion and deformation capacity of the concrete, which can adapt to different deformation joints and bear a large range of deformation and pressure, thus preventing the leakage of joint water. There are various types of externally bonded rubber waterstops, including non perforated EP type and perforated EB type, as well as other special types such as externally bonded rubber waterstops with high vertical bars and low vertical bars. In addition, there are reinforced external rubber waterstop, perforated EB type

1、 The P-type rubber waterstop used for gate water seal mainly plays a key role in preventing water leakage, which is shown in the following aspects: 1. The gap between the seal gate and the door frame In similar hydraulic projects, the gate needs to be frequently opened and closed to control water flow. However, due to manufacturing and installation errors and other reasons, there will inevitably be a certain gap between the gate and the door frame. The P-type rubber waterstop is installed at this gap, and the gap is tightly filled through its own elastic deformation, so as to prevent water from leaking out of the gap. For example, in the flood gate of a dam, when the gate is closed, a large amount of water flows through the P-type rubber waterstop
