The Construction Method of Shield Tunneling for long distacne

摘要

The present invention relates to a construction method of a non-excavation formula long distance tunnel structure construction the tunnel structure, a long in the ground, and more specifically, prevent subsidence that may occur during a tunnel construction in advance, and construction of the tunnel structure non-excavation formula which maintains the straightness of the tunnel structure, even if a length of the long-range precision construction is possible, and to form a plurality of tunnel unit structure assembly 80 simplifies the construction work of the long distance dollars tunnel structure, and shortening the construction period It relates to a method of long-distance tunnel construction structures. ; In the construction method of a non-excavation formula long distance tunnel structure according to the present invention, a tunnel structure in the ground in the construction method of a non-excavation formula long distance tunnel structure construction long distance in a non-excavation expression, the vertical direction to both sides of the place where the construction of the tunnel structure the first step to obtain a drilling to a predetermined depth of sphericity 10 and reaches the forming (20); A second step of the installation in the direction in which the tunnel structure is press-fitted to the lower surface of the sphericity (10) a plurality of floor rail (30) by a predetermined distance; Provide a stretching force wall 11 to the foot sphericity (10), and installed the stretching force to the front of the wall 11 has a plurality of rear indentation (13), a front surface of the rear end of the press device 13 tip structures which will transfer pipe 12 of the plurality of hollow fiber has been installed is connected to the front as is the front line feed pipe 12, formed separately from the ground and the rear inside is provided with a plurality of front end press-fit device (41) ( 40), a third step of placing on the top surface of the floor rail (30); After drilling a front of the front end structure 40 at a predetermined distance, a fourth step to the rear end of the press by operating the device 13, press-fitted in the ground by a predetermined distance to the front end of the drilling structure (40); To remove a plurality of conveying pipe (12) from the front line conveying pipe by a a drilling advance the press the predetermined distance, and removal space, a rear structure (70) formed separately from the ground to the upper surface of the floor rail (30) a fifth step of locating; Claim that the press after digging a front portion of the front end structure 40 at a predetermined distance, by operating the rear-stage press-fitting apparatus 13 to the rear structure (70) positioned at the rear along with the front end structure 40 in the ground step 6; A seventh step of the embodiment repeats the fifth step and the sixth step, the press to the front end structure 40 and a plurality of the rear structure (70) to the rear-stage hydraulic device by a predetermined distance that can be press-fitted at the same ground; After drilling a front of the front end structure 40 at a predetermined distance, the front end structure 40 by operating the plurality of front end press-fit device (41) provided on the rear inside as much as the excavation of the tip structure 40 a distance of the eighth stage of the indentation in the ground; Situ a transfer jack of the front indentation (41) and, to the transfer area of ​​the transfer jack, formed separately from the ground, to assemble the front end structure 40 a tunnel unit structure assembly 80 carried in the interior of the installation the ninth step; After the front surface of the tunnel unit structure assembly 80 which is located at the foremost conducted repeating the eighth step and the ninth step to reach the reach port 20, a plurality of the said tunnel unit structure assembly 80 characterized in that the made of; to the rear end bonding the structure (70) of claim 10 comprising: completing the entire tunnel structure. ; Non-excavation way, long tunnel construction, tunnel construction unit assembly, the rear indentation device
