This application discloses a sealing structure for seepage paths around a dewatering well, relating to the field of waterproofing technology for construction sites. The structure includes a concrete base slab and a well casing embedded therein. The well casing is cut off from the lower end of the concrete base slab upwards to form a replacement section, which is fixedly connected to the upper opening of the cut-off well casing. The lower end of the replacement section is provided with a lower annular water-stopping wing ring with a water-swellable rubber strip, and the upper end is provided with an upper annular water-stopping wing ring. The upper surface of the upper annular water-stopping wing ring is provided with a cover plate with grouting holes and vent holes. This application, through the cooperation of the replacement section and the upper and lower annular water-stopping wing rings, combined with the water-swellable rubber strip and grouting system, effectively isolates groundwater seepage paths, improves the stability and seepage prevention performance of the well sealing, and protects the waterproofing quality of the main structure.

The utility model provides a kind of bridge spherical support, it is related to bridge technical field, including support plate, the top of support plate and near center place is fixedly connected with bottom basin, the top of bottom basin is equipped with ball groove, the inside of ball groove is embedded with spherical four fluorine board, the top of spherical four fluorine board is embedded with steel lining plate, the top of steel lining plate is equipped with round groove, the inside of round groove is embedded with plane four fluorine board, the top of plane four fluorine board is attached with stainless steel plate, the top of stainless steel plate is equipped with middle plate, the four sidewalls of support plate and middle plate are equipped with mounting plate, the both ends of mounting plate are equipped with second mounting hole. In the utility model, first spring, second spring and damper cooperate, dynamic buffering load impact, when earthquake, vibration energy is greatly attenuated, protect bridge main structure;Sealing rubber ring enhances sealing, delays internal component aging, prolongs support life.
