Filling type concealed karst cave reinforcing structure at palisade crane beam part and construction method
The invention provides a filling type hidden karst cave reinforcing structure at a palisade crane beam part, which is characterized in that a pilot tunnel and a pilot well are dug in a drainage gallery at the periphery of an underground powerhouse cave, and the pilot tunnel and the pilot well are communicated with the filling type hidden karst cave at the periphery of the palisade crane beam part at a target operation area of the underground powerhouse cave; the filling type hidden karst cave is used for emptying karst cave filling objects in the filling type hidden karst cave, and backfill concrete is filled and arranged together with the pilot tunnel and the pilot shaft; the palisade crane beam part comprises a palisade crane beam and a palisade crane beam attachment wall arranged below the palisade crane beam. The method can reduce surrounding rock relaxation during excavation of the palisade crane beam part, and ensures the surrounding rock bearing capacity of the palisade crane beam part as much as possible; and the rock wall crane beam, the rock wall crane beam attachment wall, the surrounding rock and the backfill concrete are anchored and extruded together to form a combined bearing structure, so that the stability of the surrounding rock of the underground powerhouse and the structural safety of the rock wall crane beam are effectively guaranteed.
本发明提供了岩壁吊车梁部位的充填型隐伏溶洞加固结构，在地下厂房洞周边的排水廊道内挖设导洞及导井，所述导洞及导井与所述地下厂房洞目标作业区域的岩壁吊车梁部位周边的充填型隐伏溶洞连通，所述充填型隐伏溶洞对其内部溶洞充填物清空，并与所述导洞及导井共同填筑设置回填混凝土；所述岩壁吊车梁部位包括岩壁吊车梁、以及布置在所述岩壁吊车梁下方的岩壁吊车梁附壁墙。本发明可减少岩壁吊车梁部位开挖时的围岩松弛，尽量保证岩壁吊车梁部位的围岩承载力；并且将岩壁吊车梁、岩壁吊车梁附壁墙、围岩及回填混凝土锚固、挤压在一起，形成联合承载结构，从而有效保证地下厂房的围岩稳定性及岩壁吊车梁结构安全性。
