The invention discloses a prestressed concrete pipe pile irregular gripping type connecting structure. A pipe pile comprises a pile body, a reinforcement cage is mounted in the pile body, the pipe pile is of a hollow structure, the inner side of the pipe pile is a pipe pile wall, the pipe pile comprises a lower pile and an upper pile, the end of the lower pile is provided with a first protrusionwith the radius being smaller than that of the pile body, a second protrusion with the bottom radius the same with that of the first protrusion is mounted on the upper portion of the first protrusion,a three-layer reinforcement cage is mounted in the lower pile, the reinforcement cage on the innermost portion is arranged on the connecting position of the first protrusion and the second protrusion, a gripping part is mounted on the outer side of the first protrusion, the reinforcement cage on the outmost side is mounted at the position, on the outer side of the gripping part, in the pile body,the end of the upper pile is provided with a first groove and an inverted second groove, the pipe pile connecting structure is free of welding, one-time forming is achieved, cost is saved, the construction period is shortened, the upper pile and the lower pile are tightly connected, inner gripping is achieved, the pile integrality is improved, the need for the soil layer is low, and the adaptation is high.
本发明公开了一种预应力混凝土管桩不规则咬合式连接结构，所述管桩包括桩体，桩体内设置有钢筋笼，管桩为中空结构，其内侧为管桩壁，管桩包括下部桩和上部桩，下部桩的端部设有半径小于桩体半径的第一凸起，第一凸起的上部设置有底面半径与第一凸起相同的第二凸起，下部桩内设置有三层钢筋笼，其中，最内层钢筋笼设置于第一凸起与第二凸起的连接位置，第一凸起的外侧设有咬合构件，最外侧钢筋笼设置于咬合构件外侧的桩体内，上部桩的端部设有第一凹槽和倒第二凹槽。本发明的管桩连接结构，无需焊接，一次成型，节约成本，缩短工期；上下段桩紧密连接，内部咬合，提高桩的整体性；对于土层的要求很低，适用性强。
