现有水库输水调工作闸门努力钢板焊接橡皮止水闸门，因钢板锈蚀或止水橡皮老他磨损，致使闸门漏水或不能正常运行，每隔几年就需要探橡皮止水，涂防腐漆。由于资金限制或其它原因，许多小型水库输水洞不设检修闸门，维修时需降低库水位，打围堰，这样不仅影响工程正常供水，影 The existing reservoir water transfer work gate efforts to plate welding rubber water gate, due to corrosion of steel or rubber seal old him wear and tear, resulting in gate leakage or not functioning properly, every few years you need to explore the rubber seal, coated with anti-corrosion paint. Due to financial constraints or other reasons, many small reservoirs do not provide maintenance gate floodgate, maintenance of the reservoir to reduce the water level, cofferdam, this will not only affect the project normal water supply, shadow
