摘要： PURPOSE:To easily construct a vertical shaft for a shield machine by forming a wall body with new raw material precast concrete arranged with carbon fibers and other steel members at a groove section excavated while slurry is mixed, then solidifying the slurry. CONSTITUTION:A NOMST precast member 1 prestressed with a new raw material 13 made of carbon fibers in the horizontal direction is provided on a main body 3 made of precast concrete, and its width is set to about 1/2 of the opening width of a shield machine. A steel sheet pile 25, an H-steel 27, a pair of NOMOST members 1-1, 1-2, and a waling H-steel are arranged in a groove excavated while slurry such as bentonite is mixed. A chemical is injected to solidify the slurry, then the shield machine is installed and pressed to the wall face. The H-steels 27, 29 are removed, the NOMST members 1-1, 1-2 are directly excavated with the shield machine to construct a shield tunnel. A vertical shaft for the shield machine to be advanced and reached can be easily constructed for the execution under a road where height is limited.

摘要： PURPOSE:To increase the efficiency of an assembly work by intercoupling expandable support frames, where two sets of the opposite end parts of an arcuate frame material arranged in the shape of a circle are pivotally mounted and a jack is located between two sets of other opposite end parts, through a jack for moving a support frame. CONSTITUTION:A number of segments 8 arranged in an annular state are supported in a stable state by a support frame 4, expanded by means of jacks 3, until mortar 9 at a coupling part is cured and strength attains a given value. After the mortar 9 is cured and strength attains a given value, the support frame 4 is moved forward through expansion of jacks 5 for moving a support frame in a state that the support frame 4 at a front part is contracted. The support frame 4 is expanded and forced into pressure contact with a segment ring, and the support frame 4 in the rear is contracted, and through contraction of the jack 5 for moving the support frame, the support frame 4 is moved forward. Subsequently, the support frame 4 in the rear is expanded and forced into pressure contact with the segment for support.

摘要： PURPOSE:To connect steel-shell concrete segments by a method in which projected bars are provided on the ground side and inside and intermediate of the tunnel for the side plates of a steel-shell concrete sigment, a water stopper is put into the groove between the projected bars, and mortar is also packed into the space formed by the side plates and the intermediate projected bar. CONSTITUTION:A water stopper 8 is fitted into the groove between the ground side projected bar 4 and the first intermediate projected bar 6 and also into the groove between the tunnel inner wall projected bar 5 and the second intermediate projected bar 7. The stopper 8 is projected from the tops of both-side projected bars. The projected bars 4 in the steel shell 2 of each steel-shell concretes 1 to be connected, the unnel inside projected bar 5, and the first and second intermediate projected bars 6 and 7 are connected at their tops by welding. Mortar 9 is packed into the space formed by the side plates 3 of each steel shell 2 and the first and second intermediate projected bars 6 and 7 to connect the steel shells 2. Water-stop property can thus be kept and couplers can be easily connected.

摘要： PURPOSE:To improve the drilling performance by expanding or shrinking the multi-face cross section of split shield machine bodies in the longitudinal direction with a cross section expansion device and moving a preceding cutter head and a succeeding cutter head. CONSTITUTION:A shield drilling machine is propelled by a propelling jack 18, and a preceding cutter head 15a and a succeeding cutter head 15b are rotated by rotary driving devices 16a and 16b via cutter shafts 14a and 14b for drilling. When the longitudinal length of the multi-face cross section is to be changed, a hydraulic cylinder 21 is expanded or shrunk, split shield machine bodies 11a and 11b are relatively expanded or shrunk, and both cutter heads 15a and 15b are moved in the same direction. A hydraulic cylinder 25 is expanded or shrunk to keep the relative interval between both utter heads 15a and 15b at the optimum value, and the pressure in a cutter chamber 13 is secured at the desired value by the pressurized muddy water fed by a mud feed pipe 17a.

摘要： PURPOSE:To contrive the shortening of the term of construction or the like by constructing the wall body section of a vertical shaft at least for a shield excavator to pass, with concrete for using the reinforcing-bar-shaped stiffener of resin impregnated with carbon fibers or the like. CONSTITUTION:On the lower floor of a vertical shaft 11 and the almost whole surface of a side wall surface, the stiffeners of reinforcing bars or the like are arranged, and concrete ia placed, and wall bodies 13 are constructed. Besides, for a wall body section 131 to be excavated, the reinforcing-bar-shaped stiffeners of resin impregnated with carbon fibers or the like are used in place of reinforcing bars, and as the aggregates of the concrete, artificial aggregates or the like for example are used, respectively. After that, a shield excavator 12 is positionally adjusted to a water-proof device 14 set in the shape of a ring in the wall 131. Then, by a shield jack 15, the excavator 12 is moved forward, and the section 131 is excavated with an excavating edge. Accordingly, a cost can be reduced, and the term of construction can be shortened, and a safety degree can be improved.

摘要： PURPOSE:To efficiently construct the internal periphery of an up-and-down tunnel in safety by constructing the segment of the internal periphery of an upper tunnel part on the already-constructed segment of the internal periphery of a lower tunnel with construction delay of 1 to 1.5 ring. CONSTITUTION:Upper tunnel part and lower tunnel part are excavated to proceed synchronously by a shield machine 1, and behind the machine 1 the internal peripheries of the upper and the lower tunnel part are constructed with segments 5 and 6, respectively. For assembly of the segments, the segment 5 of the lower tunnel is first assembled and the segment 6 of the upper tunnel is assembled on the already-assembled segment 5 with delay of 1 to 1.5 ring. Similarly, in the following construction the synchronous excavation by the shield machine 1 and the lag-time assembly of the segments 5 and 6 are executed and the tunnel is constructed through its full length.

摘要： PURPOSE:To disperse and absorb stress generated in a road pavement section due to the expansion and contraction of a distance between bridge girders extending over a wide range, and to prevent cracking and a swelling phenomenon by installing an elastically deformed expansion plate and an elastic sheet at the end section of the bridge girder. CONSTITUTION:An expansion plate 3 made of steel has a protruding section filled with fillers 7 intruding in a clearance between bridge girders 1, 2, an elastic sheet 8A of approximately 4m in length in the direction of travelling is positioned onto the expansion plate 3 centering around the upper section of the protruding section, and an asphalt road pavement section is formed onto the elastic sheet 8A. The pavement section is composed of a first layer 10 and a second layer 11, and a wire gauze 12 is buried between the layers 10 and 11 in order to prevent the fine cracking of a paving surface. The elastic sheet 8A, the bridge girders 1, 2 and the first layer 11 are joined by a rubber asphalt group synthetic resin.
