Seepage-stopping drainage structure suitable for interlayer staggered belt of underground powerhouse
The invention relates to a seepage-stopping drainage structure suitable for an interlayer staggered belt of an underground powerhouse. The seepage-stopping drainage structure aims to prevent water seepage of the interlayer staggered belt from entering a channel of a factory building and reduce the possibility of staggered deformation of the interlayer staggered belt caused by water seepage. According to the technical scheme, a grouting gallery and an anti-seepage curtain are arranged on the upstream side of the underground powerhouse, a seepage-stopping drainage tunnel arranged along the interlayer staggered belt is arranged between the anti-seepage curtain and the underground powerhouse, the interlayer staggered belt is located in the middle of a cavern of the seepage-stopping drainage tunnel, inverted filtering structures are arranged in the areas, corresponding to the interlayer staggered belts, of the upstream side and the downstream side of the seepage-stopping drainage tunnel, and the inverted filtering structures are formed by backfilling inverted filtering materials after fillings on the upstream side and the downstream side of the seepage-stopping drainage tunnel are dug out. The seepage-stopping drainage structure is suitable for underground space engineering such as hydropower and water conservancy.
本发明涉及一种适用于地下厂房中层间错动带的截渗排水结构。本发明的目的是以阻隔层间错动带渗水至厂房的通道，降低渗水可能导致层间错动带错动变形。本发明的技术方案是：一种适用于地下厂房中层间错动带的截渗排水结构，地下厂房上游侧设有灌浆廊道和防渗帷幕，所述防渗帷幕与地下厂房之间设有沿层间错动带布置的截渗排水洞，层间错动带位于截渗排水洞洞室中间；所述截渗排水洞上、下游对应所述层间错动带区域设有反滤结构，该反滤结构由挖除截渗排水洞上、下游侧充填物后回填反滤料后形成。本发明适用于水电、水利等地下空间工程。
