摘要： PURPOSE:To accurately inspect whether or not where is a gap part at an inspection place by detecting impulsive vibration applied to the inspection part by a hammer part and processing the signal of the impulsive vibration. CONSTITUTION:The inspection surface 7 is given the impulsive vibration by the hammer part 1 and the vibration is detected by a sensor part 2. The signal of the impulsive vibration detected by the sensor part 2 is processed by a decision part 3 to decide whether or not there is a gap in the inspection surface 7 and the decision result of the decision part 3 is displayed on a display part 4. For example, a grout material is charged between a new inserted pipe and an existent pipe and if there is a gap part in the grout charged part, the detection waveform of the sensor part 2 becomes a vibration waveform which is long in attenuation time. Consequently, the output of an integrator 14 becomes higher than that in absence of the gap part and the number of comparators which exceed a set value among comparators 15a - 15f increases and the number of LEDs which illuminate among LEDs 22a - 22f increases, so whether or not there is a gap part and its size can accurately be detected. Therefore, the inspection is enabled without any individual difference in decision result.

摘要： PURPOSE:To reduce bending moment acting on the lining repairing material of the bottom for making the thickness of plates smaller by a method in which a downwardly projecting anchor is fixed to the bottom of a lining repairing material for the inner wall of an existing tunnel, and a grout is packed into the aperture between them. CONSTITUTION:An anchor 3 is set along the center of the bottom concrete, and spacers 5 of the same level as the anchor 3 are set at an adequate interval on both sides. Steel bottom lining repairing materials 6 and 7 are laid over the anchor 3 and the spacers 5 and integrally fixed by welding, and grout 4 is packed into the aperture 8 with the tunnel 1. After the grout is hardened, both ends of a steel upper lining repairing material analogous to but smaller than the arch of the tunnel 1 are connected by welding 10 to the other ends of the materials 6 and 7 to make up a lining repairing material 2. Grout 4 is injected from a grout injection port 11 into remaining aperture with the tunnel 1.

摘要： PROBLEM TO BE SOLVED: To provide a double water intake pipe for deep water, and a construction method for therefor, capable of simultaneously taking low-temperature deep water and high-temperature deep water, so that deep water including abundant nutrients, and having advantages of cleanness is provided for a plurality of applications. SOLUTION: In this double water intake pipe for deep water, and a method for construction thereof, the double water intake pipe 1 comprises an outer pipe 3 having excellent heat conductivity that is constructed to an intake depth for deep water, and an inner pipe 4 of less heat conductivity inserted and disposed in the outer pipe 3. A cylindrical space between the outer pipe 3 and the inner pipe 4 is set as a high-temperature water passage 6, and a space in the inner pipe 4 is set as a low-temperature water passage 7. Water intake pumps are provided on the respective passages 6 and 7, thereby deep water of different temperatures can be taken. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PURPOSE:To coat a fixed pipe with fiber reinforced resin efficiently further with good quality by piling together a non-woven fabric mat and a belt-shaped cloth on the periphery of the fixed pipe to be impregnated with reaction-setting resin and rolling the impregnated fiber on the periphery of the pipe. CONSTITUTION:A non-woven fabric mat 2a and a belt-shaped cloth 2b, longer than the mat 2a, are piled together on the periphery of a fixed pipe 1. Only the piled part is impregnated with liquid-state reaction-setting resin consisting of polyester or epoxyacrylate. After an excessive amount of resin is removed from that impregnated part, impregnated fiber is wound on the periphery of the fixed pipe 1 from its upper side, having the cross previously long formed, serving as the starting end so as to place the cross 2b in the outside. Thereafter, the cross 2b of surplus length is pasted on the existing wound impregnated fiber. As a result, the resin is prevented from providing an insufficient or exces sive amount of impregnation. Further, the impregnated fiber can be prevented from exfoliation and dislocation.
