Irrigation water diversion channel water recession system penetrating through flood drainage ditch underneath
The irrigation water diversion channel water recession system penetrating through the flood drainage ditch downwards comprises a water diversion channel and the flood drainage ditch which intersect with each other, water flows through the water diversion channel from the bottom of the flood drainage ditch through an inverted siphon pipeline, the upstream and the downstream of the inverted siphon pipeline are an upper water diversion channel and a lower water diversion channel respectively, and a water inlet of the inverted siphon pipeline is provided with a water control gate. The tail end of the upper water diversion channel is connected with the flood drainage channel through a recession gate; the water control gate is horizontally arranged at the bottom of the upper diversion channel and used for opening and closing a water inlet of the inverted siphon pipeline; a desilting basin is arranged at the bottom of the upper diversion channel at the upstream of the water control gate. The inverted siphon pipeline is used in cooperation with the water control gate, irrigation through the flood drainage ditch can be achieved, the water diversion channel can be blocked after irrigation is finished, residual water in the upper water diversion channel is guided into the flood drainage ditch through the water recession gate, and water recession is achieved.
本发明的下穿排洪沟灌溉引水渠道退水系统，包括相互交叉的引水渠道和排洪沟，引水渠道通过倒虹吸管道从排洪沟底部过水，倒虹吸管道的上游和下游分别为上引水渠道和下引水渠道，所述倒虹吸管道的入水口设置控水闸，上引水渠道尾端与排洪沟通过退水闸连接；控水闸水平设在上引水渠道底部用于开闭倒虹吸管道的入水口；控水闸上游的上引水渠道底部设置沉沙池。本发明的倒虹吸管道与控水闸配合使用，不仅能够实现过排洪沟灌溉，而且能够在灌溉结束后阻断引水渠道，并通过退水闸将上引水渠道内的残留水引入排洪沟，实现退水。
