Prefabricated downcast pipe pile in building foundation pit and use method thereof
The invention relates to a prefabricated downcast pipe pile in a building foundation pit and a use method thereof. The prefabricated downcast pipe pile is a hollow cylinder and comprises a pipe wall and a conical tip. A plurality of water permeable holes are formed in the upper portion of the pipe wall at intervals. A filter barrel is arranged inside the prefabricated downcast pipe pile, the upper end of the filter barrel is open, and the lower end of the filter barrel is closed. The use method of prefabricated downcast pipe piles sequentially includes the first step of prefabricating the prefabricated downcast pipe piles, the second step of determining the total quantity and arrangement intervals of the prefabricated downcast pipe piles, the third step of installing the prefabricated downcast pipe piles and injecting water to clean the piles one by one, the fourth step of placing immersible pumps and water outlet pipes into the prefabricated downcast pipe piles, and the fifth step of stopping the immersible pumps from pumping water, cleaning holes, injecting cement mortar, and making part of the cement mortar permeate outwards via the water permeable holes and solidify to the outside soil of the prefabricate downcast pipe piles. By means of the prefabricated downcast pipe pile, the construction period of pipe wells is shortened. Meanwhile, the anti-floating performance of the prefabricated downcast pipe pile is improved by changing the pile to be an uplift pile.
