摘要： The present invention relates to method for filling deformable karst cave, and the steps are: penetrating a grouting pipe into an elastic silicone tube, penetrating the grouting pipe and the elastic silicone tube into a deformable bracket, and lowering into a karst cave; sealing the elastic silicone tube, injecting silicate resin materials into the grouting pipe, and injecting steel fiber reinforced grout to implement a “block stone-like” structure; sealing the elastic silicone tube, separating the “block stone-like” structure from the elastic silicone tube to complete a “block stone-like” structure; lowering the elastic silicone tube and the deformable bracket, sealing the elastic silicone tube, lowering the elastic silicone tube and the deformable bracket tore construct the “block stone-like” structure, and completing the filling. The present invention may effectively stabilize the karst cave, ensure safe tunnel construction and stable surrounding rocks, and improve engineering construction speed.

摘要： The present invention relates to a mechanical tunneling apparatus and process for a tunnel in a quicksand stratum. The mechanical tunneling apparatus comprises isolating apparatuses arranged at an upper end and a lower end of a supporting apparatus; an excavation apparatus arranged at a front end of the supporting apparatus; a spraying apparatus arranged on the isolating apparatuses and the excavation apparatus; a muck discharging apparatus arranged at a lower part of the supporting apparatus; and a propulsion apparatus arranged at a rear end of the supporting apparatus. The mechanical apparatus of the present invention may effectively increase a tunneling speed and safety for the tunnel in the quicksand stratum, ensure the stability of surrounding rocks of the tunnel, and reduce a large volume of collapse of the quicksand stratum due to tunnel construction disturbance.

摘要： The present invention relates to an experimental apparatus for researching characteristics of subsea tunnel at bottom of seabed under wave, comprising main control system, wave making test system, rock and soil confining pressure test system and water level regulation test system, wherein a bottom of the rock and soil confining pressure test system is connected with the water level regulation test system; a bottom of the wave making test system is connected with the rock and soil confining pressure test system; and all test systems are electrically connected with the main control system. The experimental apparatus, when being small, may simulate the situation of the subsea tunnel under a nonlinear complex wave, may consider the common action of the seabed and the wave, and may regulate water levels and soil pressures, having perfect functions and effectively exploring the effect of various aspects on the subsea tunnel.
