Pre-consolidation grouting system for top arch and side wall of large underground cavern
According to the pre-consolidation grouting system for the top arch and the side wall of the large underground cavern, top arch and end wall first-order pre-consolidation grouting holes are drilled in the top arch of a plant through a grouting gallery, and pre-consolidation grouting is conducted on grouting sections of the top arch and end wall first-order pre-consolidation grouting holes through the top arch and end wall first-order pre-consolidation grouting holes; non-grouting sections of the top arch and end wall first-order pre-consolidation grouting holes are backfilled through the top arch and end wall first-order pre-grouting holes, and top arch and end wall second-order pre-consolidation grouting holes are drilled in the top arch of the plant through the grouting gallery; pre-consolidation grouting is conducted on grouting sections of the top arch and end wall second-order pre-consolidation grouting holes through the top arch and end wall second-order pre-consolidation grouting holes, and backfilling is conducted on non-grouting sections of the top arch and end wall second-order pre-consolidation grouting holes through the top arch and end wall second-order pre-consolidation grouting holes; through the pre-consolidation grouting of the top arch and the end wall, the integrity of the surrounding rock is effectively improved before the top arch and the end wall are excavated, and the stability of the surrounding rock is effectively improved.
本发明提供一种大型地下洞室顶拱及边墙的预固结灌浆系统，通过灌浆廊道向厂房顶拱钻设顶拱及端墙一序预固结灌浆孔，通过顶拱及端墙一序预固结灌浆孔对顶拱及端墙一序预固结灌浆孔的灌浆段进行预固结灌浆，通过顶拱及端墙一序预灌浆孔对顶拱及端墙一序预固结灌浆孔的非灌浆段进行回填，通过灌浆廊道向厂房顶拱钻设顶拱及端墙二序预固结灌浆孔，通过顶拱及端墙二序预固结灌浆孔对顶拱及端墙二序预固结灌浆孔的灌浆段进行预固结灌浆，通过顶拱及端墙二序预灌浆孔对顶拱及端墙二序预固结灌浆孔的非灌浆段进行回填；通过以上顶拱及端墙预固结灌浆，在顶拱及端墙开挖前有效的提高了围岩的完整性，有效的提高了围岩稳定性。
