Prefabricated skirt type pipe pile used for drainage and added with pile body inclined support and construction method thereof
The invention discloses a prefabricated skirt type pipe pile used for drainage and added with a pile body inclined support and a construction method thereof. The prefabricated skirt type pipe pile with a perforated pile body is provided with multiple laps of rectangular through hole structures on the side wall at intervals in the axial direction of the pile, wherein the multiple laps of rectangular through hole structures comprise rectangular through holes uniformly distributed in the peripheral direction of the pile body at intervals; prefabricated concrete blocks are hinged and mounted at the tops of the rectangular through holes; and the external of the prefabricated skirt type pipe pile is coated with geotextile. The pipe pile is planted in a soil mass through static pressure; water in soil around the pile is drained after entering an inner pipe through the geotextile and gaps; the prefabricated concrete blocks outwards expand by angles, and the expansion angles are increased through secondary pressing and beating; such fillers as gravels are filled and compacted; and a gravel cushion layer and a grid can be filled back, or a pile bearing table can be arranged after levelness. The pile increases the pile surrounding resistance force through drainage; the concrete blocks are spread to provide lateral support force; the vertical bearing capacity can be greatly improved; the pile body settlement is effectively reduced; and the pile can be suitable for the foundation treatment under complicated geological conditions, can serve as an engineering pile after secondary pressing and beating, is free of construction noise and slurry pollution, and is low in ground disturbance.
