Cast-in-place large-diameter pipe pile casing pipe and construction method
The invention discloses a cast-in-place large-diameter pipe pile casing pipe which comprises a main casing pipe body, a lower-end outer casing pipe body, feeding pipes and a valve pile shoe. The main casing pipe body and the lower-end outer casing pipe body are concentric cylindrical barrels, the lower end of the outer side of the main casing pipe body is sleeved with the lower-end outer casing pipe body, and the lower-end outer casing pipe body is attached to the outer wall of the main casing pipe body to form a closed cavity. The lower end of the lower-end outer casing pipe body is connected with the valve pile shoe. The feeding pipes are arranged on the outer wall of the main casing pipe body, and the lower ends of the feeding pipes stretch in the closed cavity formed between the lower-end outer casing pipe body and the main casing pipe body. Pile-forming quality is effectively guaranteed, disturbance to soil and generation of a soil extrusion effect are reduced, and the phenomena of wall collapsing, wall shrinking, pile breaking and the like are avoided; pile subsoil is prevented from being brought upwards through the horn-shaped main casing pipe body at the upper end, and bearing capacity is increased; and the structure is simple, the principle is clear, the manufacturing cost is low, and wide application prospects and good economic and technological benefits are achieved.
