摘要： PROBLEM TO BE SOLVED: To provide a method for bringing a support and the ground into close contact which enables reduction of the cost and also disuse of a troublesome pressurization control and prevention of an adverse effect on the support, by injecting a filler into a bag body without pressurizing the filler. SOLUTION: In this method, a support 2 shaped in the same arch as an excavation face 1 is provided along the face. Bag bodies 3 are inserted between the excavation face 1 and the support 2. A curing filler such as mortar is injected into the bag bodies 3 and thereby the bag bodies 3 are expanded so that the support 2 and the excavation face 1 are brought into close contact therewith. A curing accelerating material accelerating curing of cement is added to the curing filler. The bag bodies 3 are provided with check valves. When the bag bodies 3 are interposed between the support 2 and the excavation face 1 and between the support 2 and the bottom 5 respectively, the filler to which the curing accelerating material is added is injected thereinto. In this case, the filler is injected without applying a pressure to be a pre-load on both of the excavation face 1 and the support 2, that is, without pressurizing them, and expands each bag body 3.

摘要： PROBLEM TO BE SOLVED: To provide an embankment slope reinforcing structure, by which the deformation and collapse of a slope surface layer are difficult to be generated and are stabilized and deformation can be corrected even at the time of the generation of deformation. SOLUTION: A plurality of layers of reaction plates 11 are disposed into a slope surface layer, embankment layers 12 are formed among the reaction plates 11 and the reaction plates 11 respectively, and tensile reinforcing materials 13 are connected at one ends of the reaction plates 11 and laid in the horizontal direction or laid in the horizontal direction among the reaction plates 11. Sections among the reaction plates 11 are coupled vertically by anchors 14 mutually at least every one layer from the reaction plate 11 in a lowermost layer to the reaction plate 11 in an uppermost layer.

摘要： PROBLEM TO BE SOLVED: To easily and costlessly manufacture a capsule for fixing a driving anchor bolt by filling, cooling, and solidifying molten paraffin wax in the opening of a bottomed glass tube. SOLUTION: Unsaturated polyester resin 1 and a hardener 2 are alternately filled in a bottomed glass tube 4, and glass beads 5 are filled as aggregate thereon, and further, molten paraffin wax 6 is filled, cooled and solidified, and then the opening is sealed to manufacture a capsule for fixing a driving anchor bolt. The melting point of paraffin wax 6 is 45-110 deg.C and glass beads are used to function as a heat insulating material and prevent voluminal increase caused by sealing of a separation layer 3 hardened and formed by reaction of the unsaturated polyester resin 1 and the hardener 2. Accordingly, a device such as a heat sealer or the like is not required and hence, the capsule can be easily and constlessly manufactured by sealing the bottomed glass tube 4 by paraffin wax 6 instead of heat sealing.

摘要： PROBLEM TO BE SOLVED: To freely design and change the weight and dimensions of a weight hung in water by weaving thermoplastic fibers or metallic wires having a specified diameter to form a cylindrical shape having an inner diameter within a specified range and filling weights such as stones in the inside. SOLUTION: Polyester monofilaments having 0.8 mm in the diameter are woven to form strings and constitute a flexible cylindrical structure body 11, and scrap metal pieces 14 having an apparent specific gravity of 3.5-4 and a size of 2-6 mm are charged in the cavity of the flexible cylindrical structure body 11 to constitute the weight 10. The flexible cylindrical structure body 11 having the fiber diameter of 0.1-3 mm is formed of thermoplastic fibers or metallic wires. The inner diameter of the flexible cylindrical structure body 11 is 3-100 mm. The weights to be charged are sand, stones, iron scraps, stainless steel scrups, etc. And the apparent specific gravity is 1.5 or higher. A float is attached to the upper part of the weight 10 and hung in water and it may be hung from the fence by a rope or the like. And the weight 10 may be inserted in a cylindrical bag body attached to the lower part of the fence. In this way, an inexpensive and easily handlable weight can be obtained.
