Dangerous rock mass prestress bolting and anchoring reinforcing structure and method for realizing reinforcing structure
The invention discloses a dangerous rock mass prestress bolting and anchoring reinforcing structure. The structure comprises a main rigid rod body and auxiliary rigid rod bodies, the main rigid rod body and the auxiliary rigid rod bodies are coaxially placed into drilling holes in a mother rock and dangerous rock mass respectively through cement mortar pouring, one main rigid rod body and two or more auxiliary rigid rod bodies are provided, the upper ends of the main rigid rod body and the auxiliary rigid rod body are exposed to the ground, the upper end of each auxiliary rigid rod body and the upper end of the main rigid rod body are connected through a pre-stress anchor cable. The reinforcing structure forms a multiple-to-one distribution mode, so that the dangerous rock mass is subjected to strong anchoring action of multiple points and multiple directions, and the structure can generate the strong anchoring effect; and the structure is simple and low in treatment cost, and the construction of drilling from top to bottom is low in difficulty, safe and reliable. The invention also discloses a method for realizing the dangerous rock mass prestress bolting and anchoring reinforcingstructure.
本发明公开了一种危岩体预应力栓锚加固结构，包括主刚性杆体和副刚性杆体，主刚性杆体和副刚性杆体分别由水泥砂浆同轴浇筑在母岩和危岩体上的钻孔中，主刚性杆体为一根、副刚性杆体为两根或两根以上，主刚性杆体和副刚性杆体上端分别外露于地面，各副刚性杆体与主刚性杆体上端间均由预应力锚索相连接；该加固结构构成多对一分布方式，使得危岩体受到多点位、多方向强大的锚固作用，因此本发明的结构能够产生强大的锚固效果，本发明结构简单、治理费用较低，从上往下钻孔施工难度低、安全可靠；本发明还公开了一种实现危岩体预应力栓锚加固结构的方法。
