METHOD FOR PLUGGING WATER INRUSH AND MUD OUTBURST IN LU503555
TUNNELS
The present invention belongs to the technical field of tunnels, and particularly relates to a method for plugging water inrush and mud outburst in tunnels.
In geotechnical engineering construction, various water-related problems are often encountered, and sudden water inrush and mud outburst disasters encountered in tunnel construction are extremely serious accidents. It is difficult to prevent water inrush and mud outburst in the tunnels, the geological condition in front of the excavation face 1s hidden, the exploration in the early stage of construction is generally on the mountain right above the tunnel, detailed investigation tasks are difficult to complete, and the collected geological data cannot accurately pre-judge the position where the unfavorable geology is located. According to the method, advanced geological forecast is generally required for tunnel excavation, the geological radar method, the seismic wave method, the transient electromagnetic method, the horizontal drilling method and the like can be adopted, but the method is influenced by factors such as operation surface influence, surrounding environment interference, technicians experience and the like, and the existing geophysical prospecting technology 1s difficult to detect abnormal geological conditions in front without fail.
When water inrush and mud outburst disasters occur, equipment loss is easily caused, personnel safety is threatened, and construction period delay and other adverse effects are caused. The water inrush mud outburst is a mud-water mixture to extrude and expand a rock mass crack under high- strength pressure, and when the excavation tunnel face is close to the non-good geological anomaly, the middle rock mass is difficult to support the pressure of muddy water, so that the mud is sprayed out from the weak part of the excavated tunnel face.
Therefore, it is necessary to provide an improved technical solution for the above shortcomings in the prior art.
