WATER INJECTION MERGING MEMBER, WATER SUPPLY METHOD USING SIPHON WATER SUPPLY DEVICE WITH WATER INJECTION MERGING MEMBER
To provide a water injection merging member capable of preventing flowing water from being blocked within the water injection merging member by preventing the ends of elongated floating objects from getting caught in the uneven shape forming an inside of the water injection merging member, and subsequent floating objects from getting caught on top of the caught floating objects and blocking the water flow cross section.SOLUTION: In a water injection merging member 30 used in a siphon water supply device 200 that moves water from a reservoir in a high water level area to a low area, the water injection merging member 30 comprises a linear siphon main pipe member 31 connected to a siphon water suction pipe 11, a water supply device side pipe member 32 that is provided to join an opening formed on a side surface of the siphon main pipe member 31 and is connected to a backflow prevention device or a water supply device connection pipe at an upstream end. The merging portion is provided with a switching valve via a hinge, which switches the flow of water from a side pipe member 32 for water supply device water injection and the flow of water from the siphon main pipe member 31.SELECTED DRAWING: Figure 1
【課題】細長い浮遊物の端部が注水合流部材内を形成する凹凸形状に引っ掛かり、その引っ掛かった浮遊物に後続の浮遊物が重なるように引っ掛かることで通水断面を塞ぐことを防止することで、流れて来る水が注水合流部材内で遮断されることを防止することができる注水合流部材を提供する。【解決手段】高水位域にある貯留部の水を低地域に移動させるサイフォン送水装置２００に使用される注水合流部材３０において、注水合流部材３０は、サイフォン吸水管１１と接続される直線状のサイフォン主管部材３１と、サイフォン主管部材３１の側面に形成された開口部に合流して設けられ、上流側端部で逆流防止装置又は送水機器接続管と接続される送水機器側方管部材３２とを備え、合流部には、送水機器注水用側方管部材３２からの水の流れと、サイフォン主管部材３１からの水の流れを切換える切換弁が蝶番を介して設けられていることから構成される。【選択図】図１
