Anchor rod static pressure pile pre-stressed force sealing pile structure and construction method thereof
The invention discloses an anchor rod static pressure pile pre-stressed force sealing pile structure. The anchor rod static pressure pile pre-stressed force sealing pile structure is characterized in that a frustum-shaped pile pressing hole with an upward small end is preset in the middle of an original foundation beam, the two sides of the original foundation beam are widened to form a newly-added foundation beam, the newly-added foundation beam is connected to a foundation cushion layer in an overlapped mode, a pile formed by a steel pipe is pressed into a foundation through the pile pressing hole, a small section of the top of the pile is exposed on the newly-added foundation beam, a plurality of reinforcing steel plates arranged in the axial direction are welded to the outer side edge of the small section of the pile in the radial direction according to a certain rule, the side edge of the other end of each reinforcing steel plate is welded to an anchor rod embedded in the newly-added foundation beam in the axial direction, and an anchor hook is arranged at the bottom end of each anchor rod; the pile top is connected with a bidirectional anti-crack reinforcing mesh which is welded with the top end of the anchor rod; and grouting materials are poured and tamped between the pile pressing holes and the piles. According to the anchor rod static pressure pile pre-stressed force sealing pile structure and a construction method thereof, the pile construction period is greatly shortened, the utilization rate of pile sealing equipment is high, pile bouncing can be reliably avoided, and differential settlement of the foundation can be avoided.
本发明公开了一种锚杆静压桩预加力封桩结构，在原有基础梁中间，预设有小端朝上的棱台形压桩孔，在原有基础梁的两侧加宽构成新增基础梁，新增基础梁叠加连接在基础垫层之上，由钢管构成的桩经压桩孔压入在地基中，桩的顶部有一小段露在新增基础梁的上面，在该小段桩的外侧边，沿径向依一定规律分布焊接有若干沿轴向设置的加强钢板，加强钢板的另一端侧边与沿轴向预埋在新增基础梁中的锚杆焊接，锚杆的底端设置有锚钩；桩顶连接有双向抗裂钢筋网片，网片与锚杆顶端焊接连接；压桩孔及桩的中间浇捣灌浆料。本发明提供一种极大缩短桩施工工期、封桩设备利用率高、能可靠避免桩上弹和避免地基不均匀沉降的锚杆静压桩预加力封桩结构及其施工方法。
