Vacuum grouting method and vacuum grouting structure
According to the vacuum grouting method and the vacuum grouting structure, a sleeve valve pipe set comprising a supporting pipe and a grouting pipe is arranged in an operation hole, so that slurry is discharged out of the supporting pipe through the grouting pipe and the supporting pipe in sequence to fill a structural gap of a grouting area and a gap between the grouting area and the supporting pipe; and meanwhile, a vacuum grouting mode is adopted, so that an area farther from the grouting pipe can be filled with slurry.
本发明公开一种真空注浆方法及真空注浆结构，通过在作业孔中设置包括支护管和注浆管的袖阀管组，使浆质依次经注浆管和支护管排至支护管外，以填充注浆区域的结构空隙中以及注浆区域与支护管之间的间隙中，同时采用真空注浆的方式，使浆质可填充至离注浆管更远的区域。
