Method for reinforcing aeolian sand high and steep slope construction platform and aeolian sand high and steep slope structure
The invention discloses a method for reinforcing an aeolian sand high and steep slope construction platform and an aeolian sand high and steep slope structure. The method comprises the following steps that an excavation line is measured and set out according to the self-stabilization slope rate of aeolian sand; a first-stage unloading platform is excavated in a sloping mode, high-pressure jet grouting piles are reinforced on the free side of the first-stage unloading platform, and reinforcing steel is inserted into the high-pressure jet grouting piles; after the strength of the high-pressure jet grouting piles meets the requirement, a second-stage unloading platform is excavated in a sloping mode, the high-pressure jet grouting piles are reinforced on the free side of the second-stage unloading platform, and the reinforcing steel is inserted into the high-pressure jet grouting piles; other levels of unloading platforms are excavated in sequence, and a construction operation platform is excavated after the last level of unloading platform is excavated and reinforced; and high-pressure jet grouting piles are reinforced on the construction operation platform, and the reinforcing steel is inserted into the high-pressure jet grouting piles. The problems that in the prior art, an aeolian sand slope is difficult to reinforce, damage and balance losing are likely to happen due to construction disturbance, sliding is likely to happen, and the slope is unstable are solved.
本申请公开了一种风积沙高陡边坡施工平台加固方法及风积沙高陡边坡结构，包括：根据风积沙自稳坡率，对开挖线进行测量放样；放坡开挖第一级卸载平台，并在第一级卸载平台临空侧进行高压旋喷桩加固，高压旋喷桩内插加固钢；待高压旋喷桩强度满足要求后放坡开挖第二级卸载平台，并在第二级卸载平台临空侧进行高压旋喷桩加固，高压旋喷桩内插加固钢；依次开挖其他级卸载平台，在最后一级卸载平台开挖加固完毕后开挖施工作业平台；在施工作业平台上进行高压旋喷桩加固，高压旋喷桩内插加固钢。本申请解决了相关技术中对于风积沙边坡加固困难，受到施工扰动易发生破坏失去平衡，易发生滑动，造成边坡失稳的问题。
