Method for reinforcing jointed rock mass through cooperation of pre-stressed anchor rod and precise grouting
The invention discloses a method for reinforcing a jointed rock mass through cooperation of a pre-stressed anchor rod and precise grouting, and belongs to the technical field of rock-soil mass reinforcement. The method comprises the following steps that a pre-stressed anchor rod-precise grouting cooperative reinforcement scheme is determined; preparing a construction site; grouting reinforcement is conducted on the jointed rock mass at the anchoring end of the pre-stressed anchor rod; grouting reinforcement is conducted on the jointed rock mass at the tensioning end of the pre-stressed anchor rod; and the jointed rock mass before and after reinforcement is compared, and the prestressed anchor rods are tensioned to complete reinforcement. By means of the precise grouting technology, a grouting body with a plurality of tree roots is formed at the anchoring end, the stability of a jointed rock mass is improved, and the anchoring effect of the pre-stressed anchor rod is improved; and accurate grouting is conducted on the jointed rock mass at the tensioning end, the fractured rock mass near the tensioning end is cemented, the deformation hysteresis effect of the jointed rock mass is relieved, the loss of prestress is reduced, and the effectiveness of the prestressed anchor rod is guaranteed.
一种预应力锚杆‑精准注浆协同加固节理化岩体的方法，属于岩土体加固技术领域。方法如下：确定预应力锚杆‑精准注浆的协同加固方案；施工现场准备；进行预应力锚杆的锚固端的节理化岩体注浆加固；进行预应力锚杆的张拉端的节理化岩体注浆加固；对加固前后的节理化岩体进行对比：张拉预应力锚杆完成加固。本发明通过精准注浆技术，在锚固端形成具有多支树根状的注浆体，改善了节理化岩体的稳定性，并提高了预应力锚杆的锚固效果；对张拉端的节理化岩体进行精准注浆，将张拉端附近的破碎岩体胶结，减缓节理化岩体的变形滞后效应，降低预应力的损失，保证预应力锚杆的有效性。
