摘要： PROBLEM TO BE SOLVED: To easily, reliably and efficiently perform work for arranging reinforcements in a lattice shape in a right position on a face of slope by precluding the possibility of collapsing the face of slope in the middle of execution work by obtaining sufficiently large slope face suppressing force. SOLUTION: Anchors are executed in lattice-shaped arrangement on a face of slope 12, and a bearing member 17 is installed in head parts of these anchors to obtain suppressing force of the face of slope by the bearing member 17 and the anchors. Reinforcements 13 are fitted in reinforcement fitting grooves 22, 23 arranged in four-side side plates 19 of the bearing member 17 to be arranged in a lattice shape. Mortar or concrete is sprayed on a reinforcement 13 part and a bearing member 17 part to form a lattice-shaped slope protection 11. The reinforcements 13 are fitted in the reinforcement fitting grooves 22, 23 of the side plates 19 to be rightly arranged. In this case, the face of slope can be stabilized in the stage before arranging the reinforcements 13.

摘要： PROBLEM TO BE SOLVED: To prevent plugging among stones by covering at least one face of a basket body with cobble stones and the like filled in a resin net of box shape, with unwoven fabric specified in thickness. SOLUTION: A gabion 10 comprises a basket body 11 formed of a lidded box body of square cross section, and hanging belts 12 made of synthetic fiber sewn to hang at eight points. The basket body 11 is formed of a resin net 20 made of grated synthetic fiber fabric hardened by resin. The inner surface of the basket body 11 is covered with a filter sheet 30 made of nonwoven fabric with a thickness of 1-20 mm, by sticking or sewing. Partition plates 13 made of the same material as the basket body 11, and cobble stones 14 are alternately filled in a plurality of stages in the basket body 11 to suppress the deformation of the basket body 11. When the basket body 11 is buried in an underground permeable layer, a culvert, or the like, intermixture of sediment or the like into the basket body 11, and plugging among stones are prevented, and since the filter sheet 30 is provided at the inner surface of the basket body 11, the damage of the filter sheet during work execution can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide an aqueduct in which large dragonflys, etc., can lay their eggs and which is a good living environment for their larvae. SOLUTION: This aqueduct 1 is formed by successively installing a U-shaped corrugated steel plate 2 as aqueduct members. A porous material member layer 7 having an unevenness on the surface thereof is formed by pasting, etc., a fibrous material sheet at the bottom 5, the side surface 6, etc., of the U-shaped corrugated steel plate 2. Even if there is no pile of a soil and sand in the aqueduct, the large dragonfly, etc., can lay their eggs on the porous material member layer 7. Also, since a water penetrating member 3 can pile the soil and sand in the aqueduct by its constant soil and sand capturing function and soil and sand flowing out-preventing function, and also maintains a gentle flow without blocking the water flow completely, the aqueduct is further more suitable for the egg laying place and the living place for their larvae of the large dragonflys.

摘要： PROBLEM TO BE SOLVED: To improve the effect of ground bearing by a bearing-pressure member in a method of slope stabilization construction. SOLUTION: Pits are bored to the bottom plate 12 of the bearing-pressure member 11, and grouting pipes 30 are fitted into the pits. Grout is force-fed from holes 34 connected to the grouting pipes 30, and grout is injected to the surface layer section of a ground from the grouting pipes 30 (a (b) section). A nut is screwed to the upper end section of an anchor rod 5 and clamped, tensile force applied to the anchor rod 5 is transmitted to the slope ground through the bearing-pressure member 11, and the load bearing capacity of the ground is obtained. The surface layer section of the ground is solidified, and the effect of ground bearing by the bearing-pressure member 11 is improved. Works, in which grout is injected to the surface layer section of the ground, are standardized, and workability is also enhanced.

摘要： PROBLEM TO BE SOLVED: To enlarge the range of depths to which an anchor rod can be driven and enhance the accuracy of driving the anchor rod. SOLUTION: A driver is mounted on a slender frame 2 in such a way as to be movable back and forth in its longitudinal direction. The driver (rock drill, etc.), is attached to a wire rope 16 formed into a loop as it is wound on pulleys 18, 19 which are provided, respectively, at the front and rear of the frame 2. A driving unit (hand operated winch, etc.), 17 for towing the wire rope 15 is mounted on the frame 2. During construction work, an anchor rod is attached to the driver. An anchor rod driving device is secured to some support structure provided in a construction site. The driver is operated and is towed and moved forward by the wire rope 16 with the turn of the handle 17a of the driving unit 17 to drive the anchor rod. A sufficient reaction to the driving can be secured, and a large pushing force can be obtained by the driving unit 17, so that the range of depths to which the anchor rod can be driven is enlarged. Since the driver moving along the frame 2 does not deflect, the anchor rod can be driven straight.
