Description

Technical Field

[0001] The utility model relates to the technical field of drainage inside a PHC pipe pile, and in particular to a movable negative pressure rapid drainage device. Background Art

[0002] After the construction of PHC pipe piles is completed, according to the Technical Specifications for Testing of Building Foundation Piles JGJ 106, the rest time before the bearing capacity test should not be less than 7 days. Pile cutting and pouring of pile core concrete are allowed only after the test is completed. At this time, due to the long interval, there will be water accumulation inside the pipe piles. The traditional construction method is to put a small water pump into the PHC pipe pile to pump water. Due to the small space inside the pile core, a worker is required to hoist the water pump into the pile core one by one to pump water. When the water level drops below 2 meters, the water pump is lifted up again. At this time, the water pump will run idle and easily burn out. Pumping water one by one will have the risk of burning out the water pump motor. Putting in too many water pumps will affect the construction progress, which brings technical difficulties to the construction. Summary of the invention

The water absorption pipe is used to be placed in the PHC pile or foundation pit to be drained.

[0007] Specifically, the compressed air in the air compressor flows forward along the straight pipe, which will lead to negative pressure in the cavity of the adjacent connecting pipe, thereby causing the two connected water suction pipes to generate suction, which can absorb water in the PHC pile.
