Water-permeable pipe pile system capable of accelerating soil consolidation and method of using the same
Disclosed is a water-permeable pipe pile system capable of accelerating soil consolidation. The system includes a hollow pile, an aerating device, and a drain device. Holes are evenly distributed on the wall of the pile, the bottom of the pile is closed, and a gas-tight gland is provided on the top of the pile. The aerating device includes a gas pipe and a gas pump, the lower end of the gas pipe passing through the gas-tight gland and extending into the cavity of the pile, and the upper end thereof connected to the gas pump. The drain device includes a drain pipe and a water pump, the lower end of the drain pipe passing through the gas-tight gland and extending towards the bottom of the cavity of the pile, and the upper end thereof connected to the water pump. Combining advantages of a water-permeable pipe pile and features of the high-pressure gas splitting technology, the water-permeable pipe pile system can accelerate dissipation of excess pore water pressure in the surrounding soil mass and rapidly increase the skin friction of the pile. Requirements on the bearing capacity of pipe piles and the service life of a construction are thus satisfied and desirable economic effects are achieved. Besides, the method of using the system is simple.
