Gate seal, also known as p-type rubber water stop, gate seal is an important part of the hydropower project gate, is a key component to ensure that the gate seal closed, normal operation. The gate seal material can be selected according to the specific conditions such as head height and orifice size, and the most commonly used is rubber gate water seal. Rubber seal water seal, also known as waterstop rubber or waterstop rubber, its greatest advantage is the flexibility, adapt to deformation ability; simple structure, sealing water is tight and reliable; more economical, easy installation and replacement, aging resistance, long service life.
Nbsp; P-type rubber water stop design and selection:
1, should be based on the structure of the importance of the level of deformation joint deformation and water pressure, P-type water stop using the working environment, economic factors and other conditions to consider and determine.
2. After selecting the P-type water stop tape, the sealing material and the sealing plate should be selected. The selection should also be based on the size of the deformation joint's water pressure, the deformation and the contact media. In addition, consideration should be given to the environmental factors used and the requirements of the building for exterior decoration.
Transport and storage
When the waterstop product is in transit, avoid direct sunlight and contact with heat, oil, and solvents. Finished products should be taken directly to the state dinner table debut flat, do not add weight. The storage site is best kept at -10°C-+30°C and relative humidity at 40%-80%.
Construction method
Rubber waterstops are partially or totally buried in concrete during the pouring of concrete. There are many sharp stones and sharp steel heads in concrete. Because the tear strength of plastic and rubber is 3-5 times lower than the tensile strength, once the water stop tape is punctured or torn, there is no need for a large external force to crack. It will expand, so in the process of sealing the water stop and concrete pouring, care should be taken to determine the method and the pouring pressure in order to prevent the water stoppage from being punctured and affect the water stop effect. The specific precautions are as follows:
1, the water stop belt shall not be exposed to the sun for a long time, to prevent rain, do not contact with the five highly polluting chemicals.
2. In the process of transportation and construction, prevent the mechanical and steel dam from damaging water.
3. During the construction process, the water stop belt must be securely fixed to avoid any movement during the pouring of concrete and to ensure the correct position of the water stop in the concrete.
