摘要： PROBLEM TO BE SOLVED: To provide a tunnel drilling machine in a smaller and lighter structure. SOLUTION: A drilling machine mainbody having a front body 11 and a rear body 12 can be moved forward by a shield jack 36. A cutter head 24, freely rotationally driven, is mounted in front of the front body 11 and an outbreak cutter 30 is mounted on the outer periphery thereof to be freely set in and out. A penetration ring 38 movable forward in the advancing direction is provided inside the front body 11 so as to be moved via a hydraulic jack 39 and a split penetration ring split into pieces in the peripheral direction is inserted between the penetration ring 38 moved forward and the thrust portion 41 of the hydraulic jack 39. The penetration ring 38 and the split penetration ring can be connected to each other via a connection bolt.

摘要： A segment 20 has segment units 22 obtained by dividing a cylindrical body having an appointed length into four sections along the circumferential direction. The segment units 22 are provided with a segment body 22a, a porous concrete layer 22b, water intake pores 22c, and clogging members 22d. The segment body 20a is constructed of a cast iron plate or steel plate and has an inwardly recessed portion on its outer circumferential surface. The concrete layer 22b is a porous material having water permeability, and is filled and solidified in the inwardly recessed portion 201a. The water intake pores 22c are formed on the flat bottom of two recessed portions 201a so as to penetrate the bottom, and are provided in a plurality along the circumferential direction with an appointed interval. The clogging members 22d are detachably screwed to the water intake pores 22c, wherein they clog the respective water intake pores 22c, and if the clogging members are removed, the water intake pores 22c are made open to the outside.

摘要： PCT No. PCT/JP98/03503 Sec. 371 Date Feb. 3, 1999 Sec. 102(e) Date Feb. 3, 1999 PCT Filed Aug. 6, 1998 PCT Pub. No. WO99/09297 PCT Pub. Date Feb. 25, 1999With a method for constructing a water intake pipe, a vertical shaft 10 is constructed, and a shield tunnel 12 is constructed by causing a shield driving machine to advance from the vertical shaft 10 toward a seashore by breaking the wall of the vertical shaft 10. The tunnel 12 becomes a water intake pipe after the tunnel is constructed, and is built by annularly assembling segments 14 one after another at the rear side of the shield driving machine in line with the advancement thereof. Two types of segments 14, RC segments 18 and ductile segments 20, are used. The segments 20 are provided with water intake pores clogged by clogging members. After the tunnel 12 is constructed, workmen enter the shield tunnel 12 with compressed air supplied thereinto, and remove the clogging members of the ductile segments 20. After the clogging members are removed, sea water is gradually taken into the tunnel 12 through the water intake pores 20c while lowering the compressed air pressure so that sea water does not rush into the tunnel 12.

摘要： The present invention relates to a shield driving machine by which eliminates excessive work of the ground when working at a curved section while suppressing an increase of the sinking of the ground surface and securing a quickening in the stability of segments. In the shield driving machine, a bulkhead 16 is provided at the tip end side of the shield driving machine body 14 of the shield driving machine 10. The chamber 18 which is formed by the bulkhead 16 and has the tip end side open is filled up with excavated earth and sand and is used to oppose the earth pressure and water pressure in the natural ground. A rotating shaft 22 which supports cross-shaped spokes 20 penetrates on the center axis of the bulkhead 16. At the shield driving machine 10, a plurality of openings 24 which discharge a part of the excavated earth and sand supplied from the chamber 18 to the rear side of the shield driving machine body 14 are provided at the hood portion 27.

摘要： The present invention relates to a tail structure of a shield driving machine, and in particular relates to an improvement technique of the tail sealing portion of this type of shield driving machine, in order to eliminate wearing of the tail seal. The tail structure has a first tail seal 12 and a second tail seal 14. The first tail seal 12 is provided with a tail ring 12a, a seal tube 12b and packing 12c, and the tail ring 12a is secured movably in the axial direction of a skin plate 10. The packing 12c is pressure-fitted to segments 11 in line with enlargement of the seal tube 12b and is spaced from the segments 11 in line with reduction of the seal tube 12b. The second tail seal 14 is provided with a seal tube 14a and packing 14b, wherein the packing 14b is pressure-fitted to the segments 11 in line with enlargement of the seal tube 14a and is spaced from the segments 11 in line with reduction of the seal tube 14b. When excavating, the packing 14b causes the first tail seal 12 to be pressure-fitted to the segments 11 without moving the first tail seal 12, and causes the second tail seal 14 to be spaced from the segments 11.

摘要： PROBLEM TO BE SOLVED: To avoid the generation of overwhelming feeling due to head lights of a cleaning vehicle by directing a cleaning brush unit to one of right and left directions for cleaning of a tunnel wall surface, and thereafter, directing the brush unit to the other side for cleaning so as to avoid the traveling opposite to general vehicles. SOLUTION: A first cleaning brush unit is turned to a right side of the progressing direction of a tunnel cleaning vehicle and a second cleaning brush unit is turned to a left side of the progressing direction thereof. Continuously, a third cleaning brush unit 3 is turned to a left side of the, progressing direction of the cleaning vehicle so that the third cleaning brush unit 3 abuts on a side wall, of a tunnel in an upper part of a travelling lane. Continuously, the cleaning vehicle is made to run in the traveling direction so as to clean a left side wall of an up lane. After the left side wall surface of a down lane is cleaned, direction of the cleaning brush unit is changed so as to clean the right side wall surface of the up lane and the right side wall surface of the down lane. With this structure, the tunnel cleaning vehicle always travels in the same direction with general vehicles, and the generation of overwhelming feeling to a driver of a general vehicle due to head lights of the tunnel cleaning vehicle can be prevented.
