The invention relates to the technical field of foundation construction, in particular to a foundation pit supporting prefabricated row pile with a dewatering and drainage mechanism arranged in the bottom, which comprises a concrete pouring pile, the concrete pouring pile is poured between an outer steel cylinder and an inner steel cylinder, and the bottom ends of the outer steel cylinder and the inner steel cylinder are fixed on the surface of a steel bottom plate; the foundation pit supporting prefabricated row pile with the built-in dewatering and drainage mechanism at the bottom has the beneficial effects that the concrete pouring pile is poured between the outer steel cylinder and the inner steel cylinder to be formed, so that the concrete pouring pile is not prone to being damaged, the hidden danger of exposure does not exist in a reinforcement cage composed of reinforcement hoops and vertical reinforcements, and the use strength of the row pile is ensured; a movable seat capable of climbing is additionally mounted on the surface of the anti-bending frame to carry a water pump, so that the water pump can be placed at different height positions of the anti-bending frame as required, and when the blockage problem of a water pumping pipe needs to be dredged, the movable seat climbs to the bottom of an outer steel cylinder to drive the water pumping pipe to be extracted to the top of a foundation pit; and the labor amount of drawing the water pumping pipe by workers is reduced.

    本发明涉及基础施工技术领域,具体为一种底部内置降排水机构的基坑支护预制排桩,包括混凝土浇筑桩,所述混凝土浇筑桩浇注在外钢筒和内钢筒之间,外钢筒和内钢筒的底端固定在钢底板的表面;有益效果为:本发明提出的底部内置降排水机构的基坑支护预制排桩,将混凝土浇筑桩浇注在外钢筒和内钢筒之间成型,如此混凝土浇筑桩不易被破坏,且钢筋箍圈和竖向钢筋构成的钢筋笼不存在暴露的隐患,确保排桩的使用强度;并且在抗折架的表面加装可爬升的移动座运载水泵,不仅实现根据需要将水泵摆放在抗折架的不同高度位置,并且需要对抽水管疏通堵塞问题时,将移动座爬升至外钢筒的底部,带动抽水管抽提至基坑顶,减少工作人员抽拉抽水管的劳动量。
