摘要： PURPOSE:To improve the water barrier efficiency, deformation efficiency and durability of the foundation ground of a dam, an urban public work or the like by filling grout mainly composed of silica fume or admixture grout to adequately exhibit the characteristics of grout. CONSTITUTION:Water 12, a dispersant 13 and micro silica 14 which are measured by a measuring device 11 according to the required blending are charged into a slurry mixer 15 to be stirred. The mixture is transported to an agitator 17 by a force feed pump 16 and injected into the ground by a grout pump 18. In this case, the silica has the purity of amorphous SiO of 90% or more. Thus, the grout can satisfactorily penetrate into a very small gaps between the particles so as to remarkably improve the water barrier efficiency and durability of the ground.

摘要： PURPOSE:To surely obtain the slurry excellent in penetration and accordingly capable of exhibiting excellent penetrating performance into very small crackings, etc., when poured into the ground for improving water-barrier effect, etc., of the ground by disintegrating and stirring the mixture of an ultrafine particle material, a dispersant and water by a disintegrator. CONSTITUTION:This slurry is obtained by disintegrating an ultrafine particle material into a nearly primary particle state when the ultrafine particle material (e.g. silica fume and slaked lime), a dispersant and water are mixed. Further, after the ultrafine particle material, water and 0.5wt.% of ethylene glycol or amine dispersant are disintegrated and stirred with a disintegrator, a melamine-, a polycarboxylic acid- or lignin-based dispersant is preferably added at the final stage in an amount of 3-4wt.% because this enables the improvement of disintegration efficacy. An example of the disintegrator includes a stirring- type ball mill, etc. Disintegration time is selected from a rage from 30min to 5hr depending on particle characteristics.

摘要： PURPOSE:To shorten workhours and to sharply improve workability by loading an elector-boom having a concrete spraying robot and a boring machine movable between storing and working positions on one travelling vehicle. CONSTITUTION:An extended erector boom 2 is lowered, and a timbering erector 23 is lowered to mount a timbering 6 on a receiving part 24, and the erector boom 2 and the timbering erector 23 are raised to raise the timbering 6 to a levee crown for connecting with bolts. The erector boom 2 is then shortened to be horizontally held, and a robot arm 53 is actuated to move a nozzle 54 to a spraying position for starting spraying work. In a boring process for a lock bolt, a boring machine is moved to a working position to execute the boring process for the lock bolt. A mancage 22 is moved to pour mortar, and the lockbolt is pushed into the above bored hole. Thus workability can be improved.

摘要： PURPOSE:To improve operativity and fixing property without using fixer with simple manufacture by forming an extrusion deformed part on a movable member fitted into an outer pipe member and pulling an inner face of the outer pipe member by means of movement of the movable member to push out an outer face. CONSTITUTION:Into a wave-shaped movable member 5 having an extrusion deformed part 6 in wedges in an equal pitch along a lengthwise direction, an outer pipe member 4 having a similar wave shape is fitted to form an insertion member 3. Then this insertion member 3 is inserted into an insertion hole 2, and the outer pipe member 4 is fixed by a washer 8 so that the movable member 5 is pulled from the outer pipe member 4 wherein the extrusion deformed part 6 is pushed against the inner face of the insertion hole 2 to be deformed, and the outer pipe member 4 is fixed to the hole 2. Therefore operativity is good, manufacture is easy, mass production is supported and rigid fixing is possible.

摘要： PURPOSE:To manufacture a timbering construction lock bolt excellent in durability by forming a hollow cylindrical unit, parallelly provided with a plurality of protrusive streaks, by rolling and a helical protrusive streak in the peripheral surface of the hollow cylindrical unit and providing connection parts of a drifter and a bit in both ends. CONSTITUTION:A hollow cylindrical unit 5 is formed by hot rolling, and protrusive streaks 6' are parallelly provided in the peripheral surface of the hollow cylindrical unit 5 by rolling. Next, the hollow cylindrical unit 5, whose both ends are fixedly held, is twisted at a cold temperature to work the protrusive streak 6' and a stopper protrusive streak 7' into helical protrusive streak 6 and stopper protrusive streak 7, and thread work, which serves as a drifter connecting part 3 and a machine drilling bit connecting part 4, is applied to both end parts. A machine drilling bit 8 is screw-mounted to the point end of this lock bolt and to a drifter 2 of a drilling machine 1 through a connecting cylinder 10. The machine drilling bit 8 is turned and knocked by actuating the drifter 2 to excavate the ground surface. In this way, sediment or the like can be well discharged from an excavation hole.

摘要： PURPOSE:To perform reliable and easy execution of a work by arranging a plurality of beam main materials, curved in the same shape as an excavating sectional shape, in juxtaposition at intervals of a proper distance, integrally forming the beam main materials in the shape of a truss by means of a helical lattice material, and effecting concrete lining the beam main material serving as a reinforcing bar material. CONSTITUTION:Two or more beam main materials 1 curved along an excavating sectional shape are arranged in juxtaposition with a distance therebetween, and the beams 1 are intercoupled in the shape of a truss by means of a helical lattice material 2 to build a timbering A0. The timbering A0 is divided into a plural pieces A1, A2..., which are capable of being intercoupled by means of end plates 4. The timbering A0 is located in a tunnel and is coupled to an existing part by means of tie rods 6 for securing. The timbering A0 is deformed and located in an oblique shape, a twist shape, or a helical shape, where necessary. Further, concrete may be placed by using the beam main materials serving as a reinforcing bar material. This method performs execution of a work having load capacity and rigidity and excellent following-up properties.

摘要： PROBLEM TO BE SOLVED: To provide a construction method for an isolation layer easily constructed and attaining positive isolation. SOLUTION: Shotcrete 1 is sprayed onto the excavated natural ground, and spring water permeable unwoven fabric 3 is stuck as a permeation layer onto the shotcrete 1. Elastic mortar 4 with elasticity even after hardened is sprayed onto the unwoven fabric 3 to construct the isolation layer 2. Lining concrete 5 is placed on the isolation layer 2. The isolation layer 2 thereby isolates the shotcrete 1 from the lining concrete 5.

摘要： PROBLEM TO BE SOLVED: To improve execution by supporting the lower end of an arch form along a tunnel inner wall by a lock bolt reinforcing soil and mountain of a tunnel invert part. SOLUTION: A moving form device for tunnel lining 1 is constituted of an arch form 2, a moving frame 20 integrally supporting the form 2 and a lock bolt 4, and an excavated face is disposed in a primarily lined tunnel adit 6. At this time, both lower ends of the form 2 is supported by the bolt 4 fixed in soil and mountain 5. Next, the frame 20 is composed of a gate gantry carrier providing a frame leg part 22 downward of the four corner of a working floor part 21, a self-traveling device 23 is provided on the lower end of the leg 22, and movable on a rail 31a provided in the direction of excavation. At the time of execution, since self-weight of the form 2 and side pressure of concrete placed in a space part 21 are received by the form 2 and the bolt 4, a structural body holding the form 2 in an adit 6 need not be particularly provided. As a result, structure is simplified to reduce a cost, and a sufficient working space is secured to improve efficiency.

摘要： PROBLEM TO BE SOLVED: To provide a construction method for an isolation layer easily and surely attaining isolation using a super-retarder. SOLUTION: Unwoven fabric 6 is stuck as a permeation material to the surface of shotcrete 1 sprayed onto the excavated natural ground. An isolation sheet 1 comprising a waterproof sheet 2 and a sheet 4 filled with the super- retarder 3 is stuck onto the unwoven fabric 6 so that the waterproof sheet 2 is on the unwoven fabric 6 side, and lining concrete 7 is further placed on the isolation sheet 1. Before the lining concrete 7 is hardened, the sheet 4 with the super-retarder 3 is dissolved to allow the super-retarder 3 to flow out, thus forming a hardening failure part 8 in the lining concrete 7. The hardening failure part 8 isolates the shotcrete 5 from the lining concrete 7.
