Corrosion-resistant prestressed concrete pipe pile
The invention relates to the technical field of engineering construction, in particular to a corrosion-resistant prestressed concrete pipe pile which comprises a prestressed reinforcement frame, a concrete pile body, an end plate A, an end plate B, a bearing assembly and a pile head assembly. According to the corrosion-resistant prestressed concrete pipe pile, when the pile head enters a hard soil layer and the top of the pipe pile is hammered, the upper end face of the hammering head is firstly subjected to impact force, then the pressure bearing rod and the pile head bear the impact force and protrude downwards, and when the upper end face of the hammering head is lower than the upper end face of the end plate A, the pipe pile bears the impact force and moves downwards; in this way, after the pile head protrudes, the pile body moves downwards, the resistance generated when the pile body moves downwards can be reduced, the pile head and the pressure bearing rod can share the impact load borne by the pile body in the piling process, loss of the pile body is reduced, pile body concrete is completely stored, and therefore the corrosion resistance of the pipe pile is improved.
本发明涉及工程建设技术领域，具体的说是一种耐腐蚀的预应力混凝土管桩,包括预应力钢筋架、混凝土桩身、端板A、端板B、承载组件和桩头组件，混凝土桩身的内部包裹有预应力钢筋架，预应力钢筋架的一端装卡有端板A，本发明设置的一种耐腐蚀的预应力混凝土管桩，当桩头进入硬土层后，锤击管桩顶部时，所述锤击头上端面首先受到冲击力，进而使承压杆和桩头承受冲击力向下突进，当锤击头上端面低于端板A的上端面后再由管桩承受冲击力向下运动，如此一来在桩头突进后桩身再向下运动能够降低桩身向下运动时的阻力，而桩头与承压杆能够分担打桩时桩身所承受的冲击载荷，降低桩身的损耗，使桩身混凝土保存完整从而提高管桩的耐腐蚀性能。
