摘要： PROBLEM TO BE SOLVED: To improve tenacity by installing an expansion member to be pressed into a diameter expansion section and a sleeve pushing the expansion member around a section in the vicinity of the lower section of an anchor body in a post-execution anchor inserted into an anchor hole, to which the diameter expansion section is formed. SOLUTION: An anchor hole 2 is formed to an existing concrete structure 1 by a pit for a lower hole, etc., and an undercutter is inserted into the anchor hole 2 and a diameter expanding section 2a is formed near a hole bottom. An anchor body 3 formed of a screw-knotted reinforcement is inserted into the anchor hole 2, and a sleeve 7 is drive by a driving bar and an expansion member 6 is pushed downwards. A plurality of expansion pieces 6a of the expansion member 6 are moved onto the tapered section 4a of a bolt 4, each expansion piece 6a is expanded along the tapered section 4a and pressed into the diameter expanding section 2a, and the anchor 3 is fixed into the anchor hole 2. Accordingly, the slipping-out of cracks due to an earthquake, etc., is prevented, and reinforcing bars having high tenacity can be fixed.

摘要： PURPOSE:To blockade voids in a trench by using only a natural material and to make it possible to form a continuous impervious wall by throwing swelling ores having the same volumes as that of a trench into the trench excavated in the porous ground. CONSTITUTION:The same volume of bentonite ores 5 or swelling ores as that of a trench is thrown into the trench 4 excavated in the porous ground 1 to be depth reaching an impermeable ground 3. When the bentonite ores 5 are in contact with underground water, the volume is swelled to blockade voids in the trench 4, and a continuous impervious wall is formed to display an impervious function. According to the constitution, the impervious wall can be easily constructed by using only a natural material and, at the same time, a cost can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a temporary pile enabling such rationalization of execution as to enable the progress of a next execution step while removing an unnecessary section with the upper temporary pile left by having only to conduct receiving replacement without driving a replacement pile by virtue of capability of easy removal such as cutting with a shield machine. SOLUTION: The lower part of the temporary pile is formed of a bag body 4 made of fibers, whereinto a solidification material such as mortar or concrete is infilled, for the purpose of being made destructible.

摘要： PROBLEM TO BE SOLVED: To provide a restoration method of a structure in which the structure can be returned to the original location while using an existing underground structure and a soft ground around the underground structure can be stabilized at the same time to prevent subsidence of the ground in the future. SOLUTION: A rise control ruler 7 is laid between piles 3 on the ground above an underground structure 1a and a hydraulic device and a pressing member 9 are installed. A buoyant force acting on the underground structure 1a becomes larger than the weight by excavating soil above the underground structure 1a and removing it and hence, the underground structure rises. The upper and lower parts of the underground structure 1b after rising are filled with a light-weight backfill material 11. Finally, the whole part or a part of the rise control ruler 7, the hydraulic device, the pressing member 9, the piles 3, and ground anchors 5 is removed.

摘要： PURPOSE:To raise the constructibility of a water-shield film wall as well as gain the exact water shielding function of joints by a method in which a water- permeable bag is provided to the ends of a water-shield sheet and packed with a self-adhesive material, the sheet is set in a trench, and the bags are bonded by the self-adhesive material. CONSTITUTION:A viscous substance-permeable bag 4, e.g. porous sponge sheet, is provided in the longitudinal direction at the ends of a water-shield sheet 2. The bags 4 are set in a lapped form in a banded trench 1, a tremie tube 5 is inserted into the bags 4, and a self-adhesive material 6 such as asphalt mortar is charged into the bags 4 in such a way as to close the trench 1 by the expanded bags 4, where the ends of the sheet 2 are put into the aperture and the bags 4 are bonded to each other by the material 6 coming from the inside of the bags 4. The aperture between the sheet 2 and the trench 1 is packed with mortar 3, etc., to exactly shut out the intrusion of water into the joint of the sheets 2.

摘要： PURPOSE:To obtain a water-shield wall of high accuracy by a method in which weights with hooks are fixed at an adequate interval to a banded trench bottom and dragged with the lopes of a water-shield sheet to draw the water-shield sheet into the banded trench. CONSTITUTION:A water-shield film wall is formed by tensely setting a water- shield sheet 2 in a banded trench 1. In this case, the banded trench 1 is excavated, weights 5 with hooks 4 are set at an adequate interval on the bottom of the trench 1, and the foots of the weight 5 are fixed with concrete 7. A cable 6 such as rope, piano wire, etc., is provided to the lower end of the sheet 2 and pulled through the hooks 4 in the trench 1 to draw the lower end of the sheet 2 into the bottom of the trench 1 tensely. The sheet 2 can thus be inserted with high accuracy to a given depth into the trench 1 for constructing a water- shield film wall.
