通过采用锚注施工工艺,对破碎松散围岩巷道采用壁后注浆加固处理后,使浆液充填和胶结围岩的裂隙,在巷道的外围形成完整的注浆帷幕,并与围岩、锚喷支护共同形成有效承压组合拱。由于注浆使得巷道外围组合拱厚度的加大,有效地提高了支护结构的承载能力,阻止巷道的变形破坏,从而确保巷道的长期安全使用。
Through the use of anchor-injection construction technology, after the grouting and surrounding rock are grouted and grouted, the grout is filled and cemented by the wall grouting reinforcement to form a complete grouting curtain at the periphery of the roadway, Support together to form an effective pressure combination arch. Due to the grouting, the thickness of the combined arch at the periphery of the roadway is increased, the bearing capacity of the supporting structure is effectively improved, the deformation and damage of the roadway are prevented, and the long-term safe use of the roadway is ensured.
