Grouting and anchor cable reinforcement is a support way that controls the deformation of roadways and guarantees the steady of roadways.
注浆及锚索加固是控制围岩变形和保证巷道稳定的一种支护方式。
Accordingly, the reinforcement measures, such as long pre-stressed cable bolting, concrete stopping wall and water control, are taken.
据此设计并采取了预应力长锚索、混凝土挡墙及防排水等综合加固措施。
In the second step, the prestressed cable is used as reinforced support to the roof plate, and the reinforcement by bolting and grouting with inside grouting bolt is applied to base Angle.
然后再采用预应力锚索对顶板进行加强支护，且对巷道底角采用内注浆锚杆进行锚注加固。
