Karst cave grouting process
The invention discloses a karst cave grouting process which comprises the following steps: firstly, sequentially dividing the area of a karst cave into a first grouting zone and a second grouting zone from outside to inside along the circumferential direction of the karst cave; the depth of the karst cave is divided into a first grouting section and a second grouting section in sequence from deep to shallow in the depth direction of the karst cave; a karst cave is divided into grouting sections in sequence from deep to shallow in the depth direction, and grouting is conducted in sequence from bottom to top in a segmented mode. According to the technical scheme, the karst cave grouting efficiency can be improved, and the time consumed for filling the karst cave is shortened.
本发明公开一种溶洞注浆工艺，其中，溶洞注浆工艺先沿所述溶洞的周向方向由外到内依次将所述溶洞的区域至少划分有第一注浆带和第二注浆带，再沿所述溶洞的深度方向由深到浅依次将所述溶洞的深度划分第一注浆段和第二注浆段；通过将溶洞沿深度方向由深到浅依次划分注浆段，并由下到上依次分段注浆。本发明技术方案能够提高溶洞注浆的效率，缩短填充溶洞所需要耗费的时间。
