Construction method for underwater compression-resistant and pulling-resistant end bearing pile
According to the construction method for the underwater compression-resistant and uplift-resistant concrete-filled steel tube end bearing pile, the reaming self-locking anchor rod is installed in an end bearing pile hole and anchored into a rock layer, then a reinforcing mesh is placed in the hole, common concrete is poured, and the end bearing pile is constructed. The end bearing pile capable of resisting pressure and pulling can be constructed on a light small platform through a small drilling machine, the erection process and cost of a complex large construction platform are reduced, large engineering piling machines are not used, the method is suitable for various scenes where the sites are complex and large machines are difficult to enter, and the construction efficiency and the engineering economic benefits are greatly improved.
本发明公开的一种用于水下抗压和抗拔钢管混凝土端承桩施工方法，通过在端承桩孔内安装扩孔自锁锚杆锚入岩石层内，然后在孔内放置钢筋网，灌注普通混凝土，可实现在轻便的小型平台上采用小型钻机施工既能抗压又可抗拔的端承桩，减少了复杂的大型施工平台搭设过程与费用，不使用大型工程打桩机械，适用于各类场地复杂、大型机械难以进入的场景，大大提高了施工效率与工程经济效益。
