Abstract: 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.

Abstract: A volume measurement system and method for a closed water-filled karst cave, including a water collecting device, concentration tester and control system. The control system is connected to the water collecting device by a connecting piece. The water collecting device is a container with a top closed and bottom open. The water collecting device top is a piston. The piston is connected to a propulsion rod, and propulsion rod is controlled by control system to extend or retract, so as to realize the forward or backward movement of the piston. An openable and closeable placement table is hinged to the water collecting device's inner wall. The placement table is connected to piston, the placement table moves upward when piston is raised, and placement table moves downward when piston is lowered. The placement table is configured to accommodate a chemical substance. The concentration tester is configured to detect the solution's concentration.
