THE FOUNDATION REINFORCEMENT METHOD OF HAVING USED COMPOSITE FIBERGLASS REINFORCED PLASTIC REINFORCEMENT TYPE GROUTING EQUIPMENT AND THIS EQUIPMENT METHOD FOR A TUNNEL AND SLOPE

摘要

The present invention reinforces the ground in order to suppress the loosening or collapse of the ground, block the groundwater flowing out through the soil layer and rock layer around the tunnel excavation surface, and injects a polymer polyurethane injection material using a triple pipe to reinforce the surrounding ground It is an object of the present invention to provide a composite fiber reinforced plastic reinforced grouting device for tunnels and slopes and a ground reinforcement method using the same.;The composite fiber-reinforced plastic reinforced grouting device for tunnels and slopes according to the present invention for achieving the above object is made of a hollow hollow shape, a plurality of outlet holes are formed at regular intervals on the outer peripheral surface, the outer peripheral surface between the outlet holes The outer portion is fitted with a ring-shaped outer spacer with a thick thickness at one side and a wide open portion at a constant size; An inner tube which is inserted into an inner circumferential surface of the exterior and is formed of a hollow hollow shape and has a predetermined size on the outer circumferential surface and is formed of a plurality of inner spacers protruding outwardly; Inserted into the inner tube, characterized in that composed of a combined discharge pipe and the air tube made of a long thin tube shape as a whole.;In addition, the ground reinforcement method using the composite fiber reinforced plastic reinforced plastic grouting device for tunnels and slopes according to the present invention for achieving the above object comprises the steps of: drilling a target ground using a drilling equipment to form a drilling hole; Inserting a grouting device into the drilling hole; Caulking the inlet portion of the grouting device with grout material; Injecting grout material into the expandable stopper with a stopper injection hose of the grouting device; Injecting grout material into the injection hose of the grouting device; Injecting a chemical solution into the grouting device; Characterized in that the step of removing the chemical injection hose in the grouting device.;Tunnel, fiber reinforced plastic, grouting, method
