This site intends to present technical proposals on hydraulic steel structures such as hydraulic gates,
　intake and discharge equipments, silt/sand dischargers etc. which are provided harbour entrances, docks
　and locks along waterways, or dams, weirs, floodgates and power stations on rivers, or irrigation systems.

PROPOSAL５　【DRAW-OFF GATE・・OTHERS】

　Although there is no technology for draw-off gates other than the piled up siphons which satisfies the selection criteria for technical proposal, proposals can be made according to customer's requests. Details are as follows.
