How much do you know about the installation methods of domestic air - shield gates? As a professional manufacturer of domestic air - shield gates, we have the responsibility to explain it to you in detail, hoping it will be helpful to everyone.
Different situations should be dealt with by different methods. After the treatment, remove the temporary support blocks and slowly lower the jack to ensure that the upper structure returns to its original position. During the jacking - up process, careful measurement, observation, and recording should be carried out to ensure that the elevation of the beam body and the bridge deck system before and after the replacement and repair of the bearing is consistent, and to ensure the success of this process at one time.
Acceptance and Installation of Seismic Pot - type Rubber Bearings
When the bearing construction unit installs the seismic pot - type rubber bearing, the bearing pad stone should be installed. To ensure the construction quality of the seismic bearing and for the convenience of adjusting, observing, and replacing the bearing, regardless of whether the cast - in - place beam method or the precast beam method is used for construction, and regardless of the type of pot - type rubber bearing installed, it is necessary to set the bearing pad stone on the top of the pier and abutment. This mainly has two requirements:
Regarding the plane size of the bearing pad stone for the seismic bearing, it should be able to bear the load of the upper structure. Generally, both the length and width are more than 250mm larger than the lower steel plate of the pot - type bearing.
Installation: When the surface rubber layer of the domestic air - shield gate is slightly worn and the fiber fabric is not damaged, it can be repaired by pasting a rubber patch. When the local wear is more serious, the dam - bag adhesive tape can be pasted on the worn part, and the warp and weft directions of the reinforcing adhesive tape should be the same as those of the original dam bag. If the dam bag is worn through or partially torn, reinforcing adhesive tapes with the same warp and weft directions as the original dam bag can be pasted on the inner and outer surfaces of the dam bag respectively, and a sealing tape can be pasted. For a dam bag with a large - area tear, depending on the project requirements, the double - sided patching method can be used or the entire piece of adhesive tape can be replaced.
Short construction period: The domestic air - shield gate is first manufactured in the processing factory and then installed on - site. The construction speed is fast. The entire project has a simple structure, and the construction period is generally 3 to 6 months.
No water - blocking: After the water in the rubber dam bag is emptied, it clings to the bottom plate, without reducing the original river - channel cross - section. There is no need to build pier piers, gate hoist frames, and other structures, and it basically does not block water.
Good water - stop effect: The dam bag is anchored to the bottom plate and the bank wall, and can achieve almost no water seepage.
Save three major materials: The rubber dam bag is a thin and flexible structure made of man - made fiber fabrics and rubber, replacing the steel - plate, reinforced - concrete, and brick structure. The underwater structure is simple, so the consumption of the three major materials is significantly reduced. Generally, it can save 30 - 50% of steel, about 50% of concrete, and more than 60% of wood.
