The Pipe-Roof Grouting Method in the Tunnel Water-Rich Slice Excavation Reinforcement Effectiveness Research
A speed-railway double-track tunnel 1# slant hole L7 slices are extremely rich water,the weathering depth to surface 270m, layer thickness of about 25m, the main filling material for decomposed granite clip diabase, diorite, sand-like and earthy.When tunnel excavation,extremely vulnerable and water burst mud.Using pipe roof curtain grouting method reinforcement after, The entire decency granite and the diorite-porphyrite obtain reinforce effectively push densely, drills takes in the core type to have the massive cement blocks, shuts off the water the function to be good, had guaranteed effectively excavates the section the construction progress.This article used the three dimensional finite element method to construct various stages to this tunnel through the L7 slices region pipe roof grouting method to conduct the analysis research, According to the analysis results timely and reasonable arrangements for excavation footage, research results can provide a reference for similar projects.
