摘要
针对祁临高速公路中段煤矿采空区出现的塌陷和裂缝现象,根据采空区分布特征,对采空区采用注浆法和井下巷道浆砌法进行治理,并对注浆施工工艺进行了详细介绍,施工实践表明,该工艺保证了路基的稳定,提高了结石体的抗压强度。
In light of the circumstances of collapse and cracks in coal mine gob in the middle section of Qi-Lin expressway, the author carries out the treatment on the gob by the grouting method and underworkings grouting method according to the distribution characteristics of gobs, introduces the construction technology of grouting, and shows by construction practices that the technology can ensure the stability of roadbed and increase compressive strength of stone body.
