一、概述该门型系由湖南省交通设计院经多年刻苦钻研,精心设计而创制出来的。其最大的特点是:不需要任何启闭机械设备和人力、电力,只是利用水力就能使闸门沿水平方向自动开启、关闭,以达到泄洪、控制水位的目的。即洪水来时闸门依靠水力自动开启泄洪、保证上游两岸农田不受淹没,洪水退后依靠水力和门的自重又能使闸门自动关闭。并且经改进后的这 First, an overview The door type by the Hunan Provincial Communications Design Institute painstakingly studied for many years, well-designed and created. Its biggest feature is: does not require any opening and closing machinery and equipment and manpower, electricity, just the use of water can make the gate along the horizontal direction automatically open, close, in order to achieve flood discharge, the purpose of controlling the water level. That is, when the flood comes, the gate relies on hydraulic power to automatically open the flood discharge so as to ensure that the farmland on both sides of the upper reaches will not be inundated. After the flood drops, it will automatically shut down by relying on the weight of water and the door. And after the improvement of this
