Construction method of high-pressure jet grouting and cloth bag expansion anti-floating anchor rod
The invention discloses a construction method of a high-pressure jet grouting and cloth bag expansion anti-floating anchor rod. The construction method comprises the following steps: 1, preparation is conducted before construction; 2, rotary jet grouting drilling is conducted; 3, secondary grouting is conducted; and 4, reaming and anchor rod installation are conducted. According to the construction method of the anti-floating anchor rod, the construction efficiency of the anti-floating anchor rod is enhanced through the method, and the anti-floating anchor rod has high universality for complex landforms and geological foundations and is small in occupied space and higher in pulling resistance and reliability.
本发明公开了一种高压旋喷及布袋扩体抗浮锚杆施工工法，包括步骤一，施工前准备；步骤二，旋喷钻孔；步骤三，二次注浆；步骤四，扩孔和锚杆安装。本发明通过提供一种抗浮锚杆施工方法，经由此方法加强了抗浮锚杆的施工效率，面对于较为复杂的地形地貌以及地质基础，也能够具有较强的泛用性，且所占用的空间较少，抗拔力和可靠性更高。
