摘要： PROBLEM TO BE SOLVED: To provide an environmentally-friendly tilting gate being easy to install while reducing its costs and assuring its reliability when tilted. SOLUTION: The tilting gate includes a door 2 provided to receive river water and being rotatable about a bearing part 5 positioned at its lower end; an overflow plate 3 rotatably connected to the upper end of the door 2 for causing an overflow beyond the door 2 to be guided diagonally downwards; and an actuator 4 for raising and lowering the door 2. The actuator 4 is connected to the door 2 and the overflow plate 3 and the tilting gate is formed so that it is actuated to raise and lower the door 2. The actuator 4 is positioned either outside or inside the gate.

摘要： PROBLEM TO BE SOLVED: To enable ascension to the bank-body upstream side of ascending fishes, and to enable conveyance to the bank-body downstream side of soil and sand, dust, etc., dredged in a dam lake by non-power or low power. SOLUTION: When buckets 10 for a dam fish ladder are circulated and moved along a track 4 for circulating and moving the buckets and the buckets 10 are lifted to the bank-body upstream side, ascending fishes are loaded onto the buckets 10 through a loading section 6 from a fish collecting facility 2 while water is loaded into the buckets 10 under the state of half-level water. When the buckets 10 are lowered to the bank-body downstream side, dam water is loaded into the buckets 10 under the state of full water, the elevated buckets 10 and the lowered buckets 10 are given weight difference, and the buckets 10 connected in an endless manner are operated by non-power or low power. The speed of carrying of the buckets 10 is adjusted by a bucket governor 5 at the time of non-power. A lake artificial river 3 is stocked with ascending fishes loaded in the buckets 10 from the fish collecting facility 2 up to a dam lake surface through a stock section 7.

摘要： PROBLEM TO BE SOLVED: To provide an erosion control dam which prevents decrease or stop of the function as an erosion control dam and erosion of the seashore and also discharges clarified water or polluted water to the downstream side through a bypass way of the erosion control dam, and further presenting an excellent landscape. SOLUTION: Steel units having a sluice gate 5 and sand-discharge gates 8 are installed within an erosion control dam. Water flows usually on the sluice gate 5 and when sand is discharged, the sluice gate is raised and the sand- discharge gates 8 are opened. A bypass 7 is provided to guide the upstream water of the dam to the downstream side thereof. The clarified water taken from the upstream side of dam is discharged to the downstream river, bypassing the dam or the polluted water (eutrophicated water) flowing in from the upstream side of the dam is discharged to the downstream river, bypassing the erosion control dam.

摘要： PURPOSE: To prevent low frequency oscillations generated by overflow water veins and prevent noises generated by dropping of the overflow water into the water level and further, prevent extinction of fry or the like resulting from the impulses of dropping water of the overflow and make it possible to use the gate in both cases of the water pressure acting from the upstream or the downstream. CONSTITUTION: A drum 2 for overflow used as a child gate rotatably installed at the upper part of a shell is rotated to cope with the variation of the water level and adjust the height of the shell gate with the drum. The overflow water from the drum is led along the rear face of the drum for overflow and the opposite face to the water reservoir side of the shell 1 to prevent the overflow water from freely dropping to the downstream water level.

摘要： PURPOSE:To increase the workability, by suspending a clamp unit equipped at both ends of a main girder from a bridge girder so as to be detachable and transferable and inspecting the bridge by transferring the inspection unit on the main girder. CONSTITUTION:The upper end of clamp units 2 at both ends of a main girder 1 is fixed to the lower flange of a bridge girder and an inspection unit 3 is transferred therebetween along the girder 1. On transferring, the unit 2 slides on the girder 1 by the devices of respective units 2. Or the units 2 are fixed to the bridge girder to slide the girder 1. The units 2 can be freely separated between the flange clamp 4 and the lifter 6 and only the clamp 4 is attached to the bridge girder flange and the wire rope connecting the clamp 4 and the body is wound up by a hoist 8 to lift the body or lower it in order to attach or detach the units 2 on the bridge girder flange. Further, the girder 1 is moved up or down by the lifter 6 to cross over the overhang part of the bridge pier. In this way, the scaffold can be used for general purposes and safely and rapidly fixed or unifixed to inspect the bridge.

摘要： PURPOSE:To keep a net field well maintained while protecting the landscape by collecting floating objects by using a net whose one end is wound on an accommodating winch 2 installed on a dry riverbed of on one side while other end is wound on a spreading winch installed downstream on the riverbed on the other side. CONSTITUTION:A floating object collecting device is formed from a net field 3 whose one end is wound on an accommodating winch 2 installed in a riverbed 01 while other end is wound on a net field spreading winch 5 installed downstream in the riverbed on the other side through a cable for spreading 5a. In service, the net field 3 accommodated in a net field stacking yard 1 is drawn out through the cable 5a and spread across the river 04 aslant, wherein the degree of tightness of the streatched net field 3 is adjusted by adjusting cables 7. The floating objects 03 effluent from upstream are led in the direction 10 of the stream alongside the surface upstream, and those which have finally gathered at its downstream end, are landed to an effluent floating object processing device 9 using a working vehicle, etc., arranged in the riverbed 01, which is followed by the incineration process, etc.
