摘要： PROBLEM TO BE SOLVED: To accelerate the thawing of frozen soil with a small facility by burying an electric heater directly feeding an AC current to a thawing pipe for heating in the frozen soil. SOLUTION: A bottom plate 8 made of a steel plate is welded at the tip of a thawing pipe 1 made of a conducting ferromagnetic substance to close it. A nonmagnetic cylindrical conductor 2 has multiple bore holes 6 on the peripheral wall and partition plates 3 with pressure equalizing holes in it, it is concentrically stored in the thawing pipe 1, and its tip 9 is welded to the bottom plate 8 and electrically and mechanically fixed. The peripheral wall of the cylindrical conductor 2 is supported via insulators 3, 4 to electrically insulate it. The thawing pipe 1 and the cylindrical conductor 2 are connected to an AC power terminal 21. When an AC current is fed under the conditions satisfying the prescribed equation, the current is concentrated on the inner surface of the thawing pipe 1 as a skin current 31, and it nearly uniformly flows on the cylindrical conductor 2. The thawing pipe 1 is largely heated, and the cylindrical conductor 2 is additionally heated. Heat is transferred by multiple partial natural convection currents passing through the bore holes 6 in the partitioned space in the thawing pipe 1, and the difference between the upper and lower temperatures in the thawing pipe 1 is small.

摘要： PURPOSE:To prevent clogging in a circuit of pressure conveyance by a method wherein specific gravities of fibers and conveyance fluid are made equal when constructing a number of horizontal piles of fiber-reinforced soil mortar to the surface of a face, and separation and sink-and-float of the fibers are eliminated. CONSTITUTION:A number of horizontal pits 9 are drilled with a drilling machine 1 to the surface 10 of a face in a tunnel in collapsible natural ground, and fiber- reinforced soil mortar is injected into the pits. Then, horizontal piles are constructed therewith to make the face self-sustainable when tunnel excavation is executed. An admixture made of concrete milk, water glass and vinylon fibers with a mixer 3 for hardening material and a mixer 4 for principal material is discharged at a specified ratio by a proportional discharge pump 5 and is injected from the front end of bits 8 into the pits. Hoses in small diameter larger than three times of maximum fiber length are used so that the fibers are not separated sink in or float on the conveyance fluid when being conveyed, and clogging arising from interwinement of the fibers in a circuit of pressure conveyance can be eliminated. Thereby, efficiency in execution of work can be improved.

摘要： PURPOSE:To provide a compact tile separation sensing device which is convenient to carry and simple to operate by introducing such a structure that a wall surface is strucken by a hammering mechanism and the obtained striking sonic pressure and the measurements about the repulsive force are compared with the reference values for judging by a judging device. CONSTITUTION:A hammer part 10 is provided with a striking mechanism 11 and a repulsive force sensor 12 and pressed by a sensor rod 14 to an applicable tile 2 on an exterior wall 1. The striking mechanism 11 is driven to strike the tile 2, and the generated sonic pressure is measured through a microphone 13, and the repulsive force is determined by the repulsive force sensor 12. A judging device 21 judges whether the sonic pressure is lower than the reference value, i.e., whether the tile 2 is in sound condition. If no, judging is made whether the measured repulsive force is greater than the reference value, i.e., the exfoliation has occurred in a deep place - the repulsive force with shallow exfoliation is smaller than that with deep exfoliation. The corresponding control signal is given through an indicator buzzer 22 and an indication lamp 23, which is lighted green, yellow, and red depending upon sound, shallow exfoliation, and deep exfoliation.
