摘要： PURPOSE:To surely catch drifting wood having lengths largely affecting the occurrence of disasters by designing a drifting wood stopping work by appropriately setting spans between horizontal beams and between pillars from results of drifting wood catching tests and materials indicating the length distribution of drifting wood. CONSTITUTION:The span between each pillars 1 installed to the downstream side of a river in an inclined state is set at b2 and the outermost pillars 1 are respectively supported by stays 2. At the same time, a plurality of horizontal beams 3 are installed to the pillars 1 at prescribed spans. This drifting wood stopping work is designed by setting the spans between horizontal beams 3 at 0.3 m

摘要： PROBLEM TO BE SOLVED: To improve the constructing property by providing a protruding part in the space part between adjacent steel erosion control units so as to obstruct the space part. SOLUTION: A steel strut provided on the upstream side of the flowing direction of debris flow and a steel strut 2 provided on the downstream side are vertically and horizontally rigid-connected by a horizontal binder 4 on the like to form a steel erosion control unit 5. The units 5 are arranged with a space S in the cross direction of a weir bank 7 by fixing each strut 2 on the like to the foundation concrete 8 of the weir bank 7. A protruding part 10 is provided in the part of the space S between the adjacent units 5 so as to obstruct the space S, and the space S is set to a size approximate to the maximum diameter of gravels included in debris to catch the gravels and driftwood. Further, each space W in the cross direction of the weir bank 7 between the struts 2 on the like is also set to a space approximate to the maximum diameter of the gravels included in the debris. According to this, the space between the units can be largely designed and constructed since the protruding part is provided, and the number of units can be reduced to reduce the cost.

摘要： PURPOSE:To prevent the run-off of gravel and earth caught in the case of the generation of debris flow while holding an earth control function. CONSTITUTION:Solid frames 1 arranged to a riverbed 5 are such that vertical bar-shaped members 2 and horizontal bar-shaped members 3 are constructed in the shape of a grid in the directions of cross and vertical sections, the upper stream side of a river along lengthwise of the river is higher than the lower stream side thereof and that the height from the riverbed 5 of the upper most stream side to the horizontal bar-shaped members 3 is 2-3 times of a diameter of a giant gravel R. An interval between the horizontal bar-shaped members 3 on the upper side from the height is smaller than the diameter of the giant gravel R. According to the constitution, the connection of a group of giant gravel caught with the giant gravel having larger than 2-3 times of the diameter of the giant gravel R is not broken, so that the gravel and earth caught by being attributed to the breakdown of the connection of a group of giant gravel can not be made to run off again.

CONSTITUTION:A stay 2 of a steel weir, formed of a weather resistant steel, is embedded in bottom slab concrete 3. A protection wall 4 formed of concrete and synthetic resin and larger than the stay 2 is built upward from a bottom slab concrete 3 surface around the stay 2 and a gap 5 is provided between the stay 2 and the protection wall 4. The gap 5 is filled with a filler 6, such as cement mortar, the upper surface thereof is inclined toward the downstream side to guide rust into the gap 5 on the downstream side.

摘要： PROBLEM TO BE SOLVED: To provide a permeable check dam and a manufacturing method therefor, which simplify a constitution, and allow the provision of slits without imposing restrictions on the number of the slits to be provided and intervals among them. SOLUTION: This permeable check dam 1 of a concrete gravity dam permits running earth and rocks to flow downstream in an ordinary deluge, and inhibits the running earth and rocks from flowing downstream in an abnormal deluge. The check dam 1 has: a concrete structure 2 of plain concrete construction, which is equipped with the slits 3 for making the earth and the rocks permeate to a downstream side, and laid so as to block the downstream flow of the earth and the rocks; and slit width holding mechanisms 4 which are provided in upper ends of the respective slits 3 so as to keep the slit widths of the slits 3 constant.

摘要： PROBLEM TO BE SOLVED: To provide the construction for preventing and stopping the generation of avalanche of sand and stone and capable of showing functions for preventing and stopping generation of avalanche of sand and stone for a long time without a concrete placing work. SOLUTION: A construction 1 for preventing and stopping generation of avalanche of sand and stone is formed by integrally connecting a downstream side square frame 2a and an upstream side square frame 2b through steel pipes 2c and H-shaped steels 2d, and a basket- like cylindrical body 2, from which these steel pipe 2c and the H-shaped steel 2d are projected out of the upstream side square frame 2b thereof, is continuously provided on the floor so that a lower surface of the downstream side square frame 2a of the upstream side basket-like cylindrical body 2 is arranged on the H-shaped steel 2d of the downstream side basket cylindrical body 2 and so that the projecting part of the steel pipe 2c of the downstream side basket- like cylindrical body 2 is arranged inside of the downstream side square frame 2a of the upstream side basket-like cylindrical body 2. Water included in the sand and stone layer piled in the periphery is drained, and water in the avalanche of sand and stone is drained so as to stop the sand and stone over a wide range. With this structure, functions for preventing and stopping generation of avalanche of sand and stone can be showed for a long time without placing concrete.

摘要： PURPOSE:To prevent movement of an aqueduct after an avalanche of sand and stone is captured by a method wherein the position of a beam between the columns of the central part of a permeation part of which a weir is composed is lowered to a level lower than that of a beam between other columns and by a distance shorter than a distance between the columns 1. CONSTITUTION:The position of a steel pipe beam 2 between steel pipe columns 1 at the central part of a permeation part of which a permeation type weir is composed is lowered to a level lower than that of a beam 2 between other columns 1. The position of the steel pipe beam 2 at a topmost stage between the steel pipes column 1 is gradually raised to a level higher than the position of the beam 2 between the columns 1 at the central part of the permeation part from the central part toward both sides. And the beam 2 is arranged by a distance shorter than a distance between the columns 1 below the beam 2 at a topmost stage between the columns 1. This constitution pushes out a larger quantity of stone gravels, accumulated at the beam 2 at the central part, of relatively smaller stone gravels subsequently accumulated on stone gravels having a maximum size captured by the weir, causes centralization of flowing water to a central part, and ensures an aqueduct.
