Method for carrying out steel pipe work for construction of tunnel

摘要

The present invention is a hydraulic press-fitted in the middle of the steel pipe and steel pipe as the construction of long tunnel for long tunnels relates to a construction method of steel cylinders for hameuroseo divided by the indentation of the middle period laid install a couple driving a steel pipe structure for easily forming the tunnel construction key, and leading key conduit for indentation in the ground, as it yuapjaek Pipe connections and for promoting key leading pipe by the hydraulic pressure, pushing the steel pipe and steel pipe to be inserted by the support of the new force to the rear wall of the steel pipe and steel pipe in the future lead pipe by a hydraulic cylinder for driving forward key alternately while in the construction methods of steel pipe steel pipe indentation in the ground, in the course of a continuous steel pipe after purchase of the ground soil and oil pressure considering the purchase of several steel pipes, etc., based on the leading steel pipe and steel pipe that new entrants in the rear side the separation of the head to the side and aft propulsion, but connected by an intermediate form between them yuapjaek push the leading steel pipe and tube attached to the front side of the first intermediate forward propulsion unit by pushing in the middle part of the driving side yuapjaek indentation in the ground and implementation phase; By reversing the hydraulic cylinder, but insert a new steel pipe therebetween, again pushing the middle portion in a state of revocation hydraulic pressure pushing the middle portion of the steel pipe to a rear portion inside the intermediate space propulsion generated by the head pushed by a hydraulic cylinder installed in the reaction wall hameuroseo repeat that indentation divided by the trailing step to boost promotion continuously pushing the steel pipe, steel pipe for the stresses in the structure established for key press-in force as to form a tunnel in the ground, install an intermediate driving back and forth every appropriate sections of steel pipe connected to ground and to be promoted to the press-fitted steel pipe steel pipe led by repeating the whole way as to promote proper length divided by pushing him to be resistant to the action but stress each section, regardless of the length of steel pipe steel pipe facilitates the entire length of the tunnel no matter how gildeorado it has an effect that can be press-fitted.
