Embodiment Construction
[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0038] In weak water-rich formations, when water gushes and sand gushes due to defects in the supporting structure, it is difficult to repair the conventional tunnel structure under dynamic water conditions. Sand breaches can be quickly blocked, and structural defects are pretreated to facilitate subsequent more detailed repair work.
[0039] The pretreatment device and pretreatment method are applied to weak water-rich formations. In such bottom layers, when water gushes and sand gushes occur due to defects in the tunnel support structure, a fast, convenient and economical technical method can be realized to treat them. Initial treatment and restoration.
[0040] The invention discloses a tunnel structure restoration pretreatment device in weak water-rich strata, such as figure 1 , figure 2 As shown, it includes a detachably connected tu...
