摘要： PROBLEM TO BE SOLVED: To detect the presence of water without breaking a surface layer, by heating the water within an asphalt surface layer by a microwave oscillator, and continuously monitoring and recording the temperature difference from a position free from water by an infrared camera. SOLUTION: To detect the internal water of a surface protecting layer 11 of asphalt or the like, a traveling vehicle 1 is gradually run on the surface protecting layer 11, the position of a microwave oscillator 9 is regulated by a height regulating device 14, and microwaves are emitted to the surface protecting layer 11 through a wave guide 10. The temperature is raised in the position where water is present within the surface protecting layer 11 to cause a temperature difference from the position free from water. This temperature difference is picked up by an infrared camera 8 height-regulated by a height regulating device 15, displayed on an indicator 4, and continuously monitored. In this monitor image, for example, the water part is suddenly raised in temperature and displayed by red, and the asphalt part is not raised in temperature so much and displayed by blue. According to this, the presence of water can be detected.

摘要： PROBLEM TO BE SOLVED: To construct a mass concrete structure of the required strength at high workability by applying the constitution that high fluidity concrete having the prescribed slump flow range is placed in the placement space of existing concrete in advance, and curing the high fluidity concrete after supplying coarse aggregate thereto. SOLUTION: First, placement space 2 using existing concrete 1 as a bottom part is formed, and the side of the space 2 is made by use of a form. At the process of the prior placement of high fluidity concrete, preferably lime stone powder or the like is used to substitute a part of cement and high fluidity concrete 3 blended with a thickener and prepared to have a slump flow between 60 and 80 cm is placed in the space 2. Thereafter but before the lapse of long time, coarse aggregate 4 is supplied to the high fluidity concrete 3 from an upper position. As a result, the level of the placed concrete rises and in this case, placement height after the supply of the coarse aggregate 4 is preferably set at a level approximately between 50 and 100 cm.

摘要： PURPOSE:To secure a permanent safety in burying low-level radioactive wastes in the ground by filling an interspace with cementitious mortar blended with velan gum and dispersant in a specific ratio. CONSTITUTION:An interspace between objects buried in the ground is filled with cementitious mortar, which is solidified. With the unit water volume of 200 to 250kg/m and with a low cement content (the ratio of water to cement: 70 to 400%), the mortar is prepared from impalpable powder (not including cement) of 50 to 800kg/m whose average grain diameter is 10mum or less, fine aggregates of 800 to 1200kg/m , velan gum of 20g/ to 1.3kg/m , dispersant of 0 to 40kg/m and inflator of 0 to 40kg/m . By injecting the mortar blended with velan gum, every interspace is filled solidly and bleeding is prevented. Moreover, the small cement content dissipates fears of cracks due to the change of temperature. Therefore, a permanent filling condition free from any interspaces can be maintained and environmental pollution due to radioactive wastes can be prevented.

摘要： PURPOSE:To prevent the surface quality of a soil structure from deteriorating, by coating the surface of the soil structure with a water-repellent and air- permeable sheet during rainfall. CONSTITUTION:When a soil structure 1 is covered with a water-repellent and air-permeable sheet 2, rain water becomes surface water 4 flowing on the surface of the sheet and it is drained and vapour 5 is dispersed outward through the clearances of sheet 2. When the soil structure 1 is covered with a laminate material composed of a water-repellent and air-permeable sheet 2 and an air- permeable water absorbent 6, water becomes surface water 4 and it drained and the vapour 5 is dispersed through the clearance of the sheet 2 and the water-absorbing material and the condensed water 7 is absorbed into the water- absorbing material 6. When it is covered with a laminated material of an air- impermeable waterproof sheet 8 and a water-absorbing material 9, rain water becomes surface water and it is drained and the vapour becomes condesate 7 at the underface of the sheet 8 and it is absorbed in the water absorbing material 9.

摘要： PURPOSE:To eliminate temperature dependence and improve segregation resistacne and fluidity of concrete by compounding xantane gum of a biopolymer. CONSTITUTION:Xantane gum of a biopolymer of the formula (M is Na, K or 1/2Ca) is obtained by fermenting glucose with a microbial species of Xarthomonas campestris at 25-33 deg.C. An admixture for the prevention of concrete segregation is obtained from the xantane gum, optionally by compounding it with other water-soluble polymer for the prevention of concrete segregation use. 10-2000g of this admixture is compounded with 1m of concrete.

摘要： PURPOSE:To continuously and economically construct a concrete facing on the slope of a dam as well as greatly shorten the period of the construction by running vertically a paving machine on the slope of the dam. CONSTITUTION:An uncured dry-consistency fiber concrete is delivered onto the top 1 of a dam by a dump truck 2 and a facing concrete is continuously constructed in a belt-like form by means of a paving machine running vertically on the slope. The paving machine consists of a finisher 3 to be dragged by a main winch porter and a vibrating roller 4. The face of foundation is compacted by a dumper vehicle 6 while delivering concrete. The vibrating roller 4' for finishing and compaction is dragged for final compaction and a joint cutter is run before the concrete is hardened following the compaction.

摘要： PURPOSE:To prevent generation of air pits by arranging a lattice member on the position of covering instead of an upper formwork, and placing concrete. CONSTITUTION:A lattice member 7 is made of fiber reinforced plastics, and CFRP (carbon fiber reinforcement), GFRP (glass fiber reinforcement), AFRP (aramid fiber reinforcement), or the like is formed into bars so as to assemble a lattice. The interval of the lattice is determined according to the used coarse aggregate of concrete, the property of concrete, and the like. Such lattice member 7 is arranged on the position of covering of concrete of reinforcement 4 instead of a customary upper formwork and concrete is placed. At placing concrete, coarse aggregate is obstructed with the lattice member 7, and mortar only exuded on the surface. The exuded mortar part is finished by troweling so as to prevent generation of air pits, and after removing the formwork, a finely finished structure without any air pits on the upper face of projections 2 is obtained.

摘要： PURPOSE:To produce a soil mortar excellent in fluidity and strength from the soil generated on the spot without using a clay mineral by kneading the soil generated on the sot, a cement caking material, water and a specified biogum. CONSTITUTION:The soil mortar is obtained by kneading the soil generated on the spot, a cement caking material, water and the biogum selected from welan-gum, xanthan-gum or succinoglucan. This soil mortar is prepared by mixing 700-1000kg soil and 0.1-5.0kg biogum per m of the soil mortar, and the water/cement caking material is controlled to 100-800%. The fluidity of the mortar is further improved by adding an appropriate amt. of dispersant.

摘要： PURPOSE:To provide a waste disposal field with a water leakage monitoring device detecting the occurrence and position of water leakage by means of a simple structure. CONSTITUTION:A water shielding inside film body 1 and a water shielding outside film body 2 are overlapped each other and arranged on the bottom face of a waste storage space. Plural high resistive elements R, which face the whole area of the bottom face, the dispesedly arranged between the inside film body 1 and the outside film body 2, and the high resistive elements R are connected in series by a resistive connection wire T. Over the overall length of the resistive connection wire T, a bare lead wire H is arranged in parallel with the resistive connection wire T between the inside film body 1 and the outside film body 2. A resistance meter 3 is connected between one end of the resistive connection wire T and one end of the bare lead wire H, and the number of the high resistive elements R between the high resistive element, which is substantially short-circuited to the bare lead wire H because of water leakage, and one end of the resistive connection wire T is found on the basis of the measured value of the resistance meter 3, and consequently, the occurrence of water leakage and the leakage position are monitored.
