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 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： 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.

摘要： PROBLEM TO BE SOLVED: To easily remove stains adhering to the wall face of a tunnel or the like without using washing water.
SOLUTION: Deposits adhering as stains to the inner wall face 100 of a tunnel are removed by a stain removal apparatus 1. The stain removal apparatus comprises a heat radiation part 2 provided with a halogen lamp and burns and evaporates the deposits for removing the deposits by radiation heat by radiating light from the halogen lamp of the heat radiation part 2. Further, air is blown to the part where the combustion and evaporation is carried out by a blower 5 and at the same time the wall face to which the burned and evaporated deposits is cooled by air from a compressor 6. Since the stains of the inner circumferential wall face 100 are removed by burning and evaporating the deposits in such a manner, washing of the wall face 100 with washing water is made no need and noise generated in the case of removing stains with washing water is not generated.

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.
