TUNNEL FORMATION TUNNEL STRUCTURE FORM OF CONSTRUCTION WORK AND TUNNEL STRUCTURE

摘要

The present invention relates to a method for tunnel construction tunnel structures and tunnel structures formed structure,; Upwardly inclined in advance in the traveling direction so that the tunnel form of a circular or rectangular shape, such as a tunnel by the press-fitting installation stress material pipe of small diameter,; TO obtain a stable ground layer by external stresses due to the ground earth pressure is evenly transmitted to the stress material pipe to the reinforcing effect,; Ever built by the tunnel structure for a tunnel formed by a method of grouting to form a plurality of columns Chemical the tube on the upper side of the small-diameter pipe stress material in multiple stages by using a packer and then insert installed in a number of ways,; Giving to further reduce the disturbance such as your line registration inventors Patent No. 418 377 No. of all personnel, equipment and materials as well as tunnel excavation is to occur easily and more quickly than using is safe structurally, yet to further shorten the construction period It will put the object as to form a tunnel for the forming structure.; The present invention for achieving the above object is,; As in the ground terrain, such as mountain areas consisting punghwaamcheung mainly comprising alluvial soil or to the tunnel construction to form a tunnel structure which is used to strengthen the improved ground,; First nine jobs entrances of all materials and personnel as an advance base (outpost) the form in the finish the foundation and construction in the center of the planned linear to enforce tunnel status, obliquely upward to the tunnel proceed in the same direction as the tunnel the external stress by the circular or small-diameter stress material pipe 50 of a predetermined distance such that the rectangular shape of the ground earth pressure by installing the press is evenly transmitted to the stress material pipe 50 of small diameter stable ground by reinforcing functional layer and a stress step of forming a material pipe installation,; Drilling a plurality of holes (60a) on the upper side stress material pipe 50 of a small diameter provided so as to obtain a stable ground layer in response to the external stresses and, in the longitudinal direction with a plurality of one-way valve (100a) is composed of insert and the tube 100,; Or longitudinal direction is formed with a plurality of one-way valve (100a), the distal end is at the same time as drilling a plurality of holes (60a) using a drilling rig (not shown) the tube 100 is drilling bit (100a) formed integrally after insertion deep into the ground installation tube 100,; The tube 100 into the packer (packer) (110a) is inserted into the settable material injection rod 110 is provided at the front end packer (110a) is one to come to the tube 100 ends and then, slowly retracting the packer (110a) while the grouting process for out flow of grout settable material 200 into the tube 100 to the grout settable material the outer 200 via the one-way valve (100a) formed in the tube 100 to injection hayeoseo so injected into the soil, Chemical the soil characterized by construction method for forming a tunnel structure in the yirueojim it included.
