PZ type water expandable waterstop is a special type of waterstop material, also known as product type water expandable waterstop, which can expand after contacting water and form a waterproof barrier to prevent water from flowing through. PZ type water swelling waterstop is usually made of high-performance polymer material, which contains hydrophilic groups with water absorption. When these groups absorb water, they will expand into gelatinous substances, filling the surrounding gaps and cracks, thus effectively sealing the water channel. PZ type water swelling waterstop is usually used for waterproof treatment in construction projects, such as basements, tunnels, pools, reservoirs and other places. They are available

Type 653 rubber waterstop refers to the type without holes in the middle and with three small ridges on both sides. The difference between type 651 rubber waterstop and type 653 rubber waterstop is that there are no holes in the middle and it is a flat plate, also known as a medium flat rubber waterstop. The rubber waterstop is produced according to the national standard GB18173.2-2000, and the dimensional tolerance is subject to the national standard. If users have special requirements, It can be manufactured according to user requirements. Large contact surface, not easy to dislocate; The steel plate shall be connected with the reinforcement through additional installation holes, which shall be firmly fixed and not easily displaced. The good bonding between galvanized steel plate and concrete makes the waterproof performance better. Rubber waterstop, as a hydraulic engineering

1、 The basic concept of bridge bearing The bridge bearing is an important component connecting the superstructure and substructure of the bridge. It can bear the dead weight, load and external force of the bridge to keep the bridge structure stable. The main functions of bridge bearings include transferring load, adjusting the elevation and horizontal position of the bridge, releasing temperature stress and preventing displacement of the bridge structure. 2、 The type of bridge bearing According to the structural form and working principle of the bearing, the bridge bearing can be divided into the following categories: 1. Sliding bearing: The sliding bearing allows the bridge to slide freely in the vertical direction to adapt to the effects of temperature changes and seismic loads. Slide Mount

BW-96 slow expansion water swelling waterstop is a new waterproof and impermeable sealing material successfully developed on the basis of foreign products for concrete construction joints and post pouring joints. BW-96 slow expansion water swelling waterstop features 1. This type of waterstop has high expansion ratio, strong movement and supplement, strong balance and self-healing function after being placed in the construction joint, and can self seal new micro cracks due to settlement. 2. For the completed project, if there is leakage in the gap, the waterstop can be used to plug the leakage again. 3. The product can expand after encountering water to achieve the effect of water stop. 4. To

High damping building isolation rubber bearings not only have all the functions of plate bearings, but also have good isolation functions, which can effectively reduce the damage to bridges caused by earthquakes. High damping rubber bearing is one of the isolation rubber bearings. The rubber used is made of high damping rubber material, which can make the damping ratio reach 10%~16%. Its shape and structure are the same as those of natural rubber bearings, but its rubber material is viscous, can absorb energy itself, has greater ductility, can extend the natural vibration period of the structure, reduce the force of seismic effect, and use its energy dissipation characteristics to play a seismic isolation effect, reaching the lead core sandwich rubber bearings

Construction projects are divided into special fortification, key fortification, standard fortification and moderate fortification according to the use function, role in earthquake relief and other factors. Buildings such as schools, kindergartens, hospitals, elderly care institutions, children's welfare institutions, emergency command centers, emergency shelters, radio and television should take seismic fortification measures in accordance with the requirements of not less than the key fortification category. Newly built schools, kindergartens, hospitals, elderly care institutions, child welfare institutions, emergency command centers, emergency shelters, radio and television and other buildings located in high intensity fortification areas and key earthquake surveillance and defense areas shall be separated according to the relevant regulations of the State

As the connection between bridge and pier or abutment, bridge bearing bears many key functions. First, it can transfer the vertical and horizontal loads on the bridge to ensure the stability and safety of the bridge structure. Secondly, the bridge bearing can adapt to the expansion deformation of the bridge caused by temperature changes, vehicle driving and other factors, and reduce the stress concentration and damage risk of the bridge structure. In addition, the bridge bearing also has the function of absorbing seismic energy and reducing the damage degree of the bridge in the earthquake. There are many types of bridge bearings, such as pot rubber bearings, plate rubber bearings, etc. Pot type rubber bearing is a combination of steel components and rubber
