Apparatus for extension work of tunnel using the existing tunnel and constructing method for extension of tunnel using the apparatus

摘要

The present invention provides devices and tunnel construction tunnel expansion expansion using the same construction to extend the tunnel using the existing tunnel relates to a method, according to the lining of the existing tunnel to install the housing in a predetermined length, and an extended tunnel excavation unit excavated surface of a predetermined size in stages by installing drilling equipment excavator is mounted on the housing pouring concrete after placing rebar Curing the sediment forming an extended tunnel between the housing and the extended tunnel wall to wall and moat extended dwell emetic tunnel is installed and ; its construction method is slowly entering the installation of the housing on the lining of the existing tunnel and into yuapjaek Steps to Install the housing on the lining to; ; The steps for installing the drilling and excavation equipment excavator equipped with a phased expansion tunnel excavation unit on the housing; ; The steps to install the assembly unit reinforced the extended tunnel excavation and pouring concrete to form an extended curing tunnel wall; ; removing the sediment by gulto between the housing and the extended tunnel wall; ; The housing moves to the next drilling by using drilling equipment installed in the housing to install reinforced by digging a tunnel expansion unit excavation and pouring concrete curing to form a tunnel wall and extend and expand the housing tunnel Steps to conduct the thumping cave sediment between the end wall in a sequential construction of the extended tunnel; And ; extended by cleaning the road in order to communicate the traffic tunnel construction completed expansion pack and install lighting in the tunnel through the facilities of the steps to be able to use the tunnel using the existing tunnel of the tunnel to the construction of.
