为了提高圩口闸的工程效益,近几年来,我市对这项工程作了些改进,其特点是:一、因地制宜再用葫芦启门闸门是圩口闸工程的重要组成部分,是提高工程质量的关键。圩口闸闸门,一是容易受撞损坏;二是闸门漏水问题。因此,改进门型成为圩口闸设计中的一个重要课题。圩口闸是圩区联圩上的挡水建筑物,其特点和运用条件是:常开少关,平水启闭,高水关门,外挡内降,低水开门,通航引排。每届汛期,雨前则闸门敞开,相机自排;雨后则外水高涨,关闸挡水,提排腾空,预降水位。预降期间,如遇天早,圩外高水未退,圩内需引水补给灌溉水源。圩内河网中养鱼的,要加网门控制。圩口闸的上述控制运用条件,概括为
In order to improve the engineering effectiveness of the Wei-mouth, in recent years, the city made some improvements to the project, which is characterized by: First, re-use the gourd door gate is an important part of the Wei-mouth project is to improve the project The key to quality. Wei gates gate, one easily damaged by the collision; second is the gate leakage problem. Therefore, to improve the type of gate design has become an important issue. Weixu gate is polder on the dike of the watertight buildings, its characteristics and conditions of use are: often open less clearance, open and close the water, high water close the door, external block down, low water to open the door, navigation cited. Each flood season, before the rain the gate is open, the camera from the row; rain after the water rises, barrier gate water, the platoon vacated, pre-precipitation level. During the pre-drop period, in case of early morning, the high water outside the fair is not withdrawn, and the water needs to be supplied to the irrigation water supply within the fair. Fair fish in the river network, to add network door control. Wei mouth of the above control conditions, summarized as
