摘要： PROBLEM TO BE SOLVED: To carry out a secondarily placing concrete work and simultaneously form a resin coating layer on the surface of the concrete layer. SOLUTION: A coating sheet 11 on one side face of which protrusions 15 are dotted about is circularly curved with the other side in the inside and the opposite open edges 11a, 11b are connected to each other through a connection band 21 fixed to the projections 15. A secondarily placing concrete form is pressed on the inside to dispose it to fit along the form. Then, concrete is placed between the segment and the form to coat the pipe line with the secondarily placing concrete.

摘要： PROBLEM TO BE SOLVED: To reduce an amount of wear of a cutter bit by eccentrically supporting a cutter part on a rotator fixed on the front end of a driving shaft, providing a step on the adjacent cutter bits, and overlapping excavated holes. SOLUTION: First to fourth cutter bits 31-34 different in length are used for a cutter part 30. Steps are provided on the adjacent cutter bits, an excavation hole through each cutter bit 31-34 is made substantially circular shape or substantially annular shape, and the cutting locus the adjacent cutter bits are overalapped to partially. Thereby when cutting is performed, a step is produced in the direction of excavation, an already cut preceding cutting part 40 is produced between the cut locus 35 of the cutter bit 31 and the cut track 36 of the bit 32. After the bit is previously cut, the bit 32 simply passes the cut part 40. Thereby the cutting torque of the bit 32 and pushing force are unnecessitated, and miniaturization of a hydraulic unit and a driving motor can be contrived.

摘要： PROBLEM TO BE SOLVED: To sharply suppress the occurrence of rolling and pitching on an excavator by installing multiple split small cutter heads in the plane facing a working face, connecting each small cutter head to an independent cutter drive section respectively, and independently applying a parallel link motion to each small cutter head. SOLUTION: A cutter head 6 is divided into four small cutter heads 6a-6d, four small cutter heads 6a-6d are arranged at the upper, lower, right and left positions, parallel link motions in the opposite directions having the revolving speed suitable for the soil quality of the natural ground G to be excavated are applied to the small cutter heads 6a-6d adjoining vertically and laterally to excavate the natural ground G. The torque reaction of the whole cutter head caused by the excavation of the natural ground G when the parallel link motion is applied to the single cutter head with a large cross sectional area can be reduced, thereby the occurrence of rolling and pitching of a shield machine can be sharply suppressed.

SOLUTION: An underground excavator 20 having a constitution wherein a plurality of separate shield machines are connected separably, with a connecting shield machine held between, so that they enable excavation of a tunnel 23 of a section of an underground railway double track station part, in the connected state and wherein the separate shield machines are separated by removing the connecting shield machine so that a plurality of small-section tunnels can be so excavated by each separate shield machine as to branch off from the tunnel 23 of the section of the underground railway double track station part. Each shield machine is provided with excavating parts which excavate a face by conducting parallel link movement respectively, and at the time of excavation of the tunnel 23 of the section of the underground railway double track station part, setting is made so that the excavating parts may excavate the face by conducting the parallel link movement integrally.

摘要： PROBLEM TO BE SOLVED: To provide an underground excavator capable of varying a cross section in a number of ways and minimizing separated portions when a large- cross-section tunnel is changed into a small-cross-section tunnel, and a method for constructing tunnels. SOLUTION: A first cutter head 37 for excavating the natural ground is disposed in such a way as to be capable of parallel link movement on eccentric multiple axes and a second cutter head 59 for excavating the natural ground is disposed on the outside of the first cutter head 37 in such a way as to be capable of parallel link movement on eccentric multiple axes. A tandem circular cross section serving as a first excavation range excavated by the first cutter head 37 continues with a cross section corresponding to a dent serving as a second excavation range excavated by the second cutter head 59, and the latter cross section is provided on a portion of the periphery of the tandem circular cross section. The second cutter head 59 is separable from the first cutter head 37.

摘要： PROBLEM TO BE SOLVED: To excavate branched passages without requiring an expensive soil improvement by using double track tunnel-excavating and branched two tunnel- excavating tail seals by separable two shielding machines. SOLUTION: Two shielding machines 2 are separably joined together, and a single double-track tunnel is separated into two single track tunnels, and branched passages are constructed. The shielding machines 2 have quadrangular outer shell parts 5, and a cutout part 5c is formed in the rear end vertical wall 5b of both outer shell parts 5. A front tail seal 16 and a rear tail seal 17 of the outer shell parts 5 are arranged at every two rows in parallel to each other. The tail seal 16 is arranged in a part except for the cutout part 5c, and divided segments are connected to a joint segment by an intermediate column segment, and a double track tunnel is formed. After being branched, the segments are set to the rear tail seal 17, and the cutout part 5c of the vertical part 5b is blocked up, and is connected in an annular shape. Work can be performed without being directly exposed to bedrock, and there is no need to perform an expensive soil improvement.
