Problems solved by technology

[0002] At present, in water conservancy projects, a steel gate is lifted up and down to block water or flood. When the steel gate is installed in the river, a middle pier must be built every 10 meters to fix the lifting equipment. When the length of the river is long, pier is required. There are a large number, which forms a water block, which is not conducive to flood drainage, and sometimes the floating objects are easy to block the steel gate, and cannot be discharged in time as required, and are easy to damage the steel gate, and the cost is high, and the investment is large; there are also lodging Steel gates, but a middle pier must be installed every 10 meters. The hydraulic system or hoist is installed on the concrete middle pier, and the steel wire rope is used to undulate, and each middle pier is 2 meters wide. According to a 100-meter river channel, there is a middle pier every 10 meters. , a total of 9 middle piers are needed to reach a width of 18 meters, which will seriously block the water and affect the flood discharge
