Quick supporting construction process for strong unloading cracked rock high slope
The invention discloses a quick supporting construction process for a strong unloading cracked rock high slope. The whole construction step of excavation and supporting is divided into three steps: excavating and grouting, slope surface reinforcing and slope surface shaping. The process comprises the following steps of first, carrying out excavating and grouting to excavate the slope to a step-by-step step slope surface; continuously excavating a second step after excavating and grouting of the first step slope surface and starting the slope surface reinforcing step of the first step; and completing the slope surface reinforcing step of the first step to reinforce the slope surface of the second step and shape the slope surface of the first step, wherein a three-step type assembly line operation is carried out between adjacent steps of the three steps by keeping one step downward till all steps are constructed. The process has the advantages of being short in construction time, shortening the joining times of the steps effectively, reducing a pore-forming problem, ensuring full grouting of an anchoring segment and not interfering synchronous construction assembly operations of thethree steps.
本发明公开了一种强卸荷破碎岩质高边坡快速支护施工工艺，将开挖及支护的整个施工工序分为开挖注浆、坡面加固和坡面整形三个步骤，首先进行开挖注浆将边坡挖成逐级的台阶坡面，完成第一个台阶坡面的开挖注浆后继续开挖第二个台阶并开始第一个台阶的坡面加固步骤，完成第一个台阶的坡面加固步骤进行第二个台阶的坡面加固及第一个台阶的坡面整形，三个步骤之间相邻步骤保持一个台阶差向下进行三台阶式流水线作业直至全部台阶施工完成，本发明具有施工时间短、各工序之间的衔接时间有效缩短、减少了造孔问题、确保锚固段注浆饱满、三台阶同步施工流水作业互不干扰的优点。
