Lossless dam-passing desilting method applied to flat steel gate
The invention discloses a lossless dam-passing desilting method applied to a flat steel gate. The lossless dam-passing desilting method comprises the following steps that firstly, a reservoir bulkhead gate is closed; a gate butt joint device is fixedly arranged in the center of the flat steel gate; the outlet end of the gate butt joint device on the downstream side of the flat steel gate is connected with a lockage control device; the outlet end of the lockage control device is connected with a downstream desilting device; closing the lockage control device, and connecting an upstream desilting device to the inlet end of the gate butt joint device on the downstream side of the flat steel gate; and the lockage control device and the downstream desilting device are opened, and pipeline desilting operation is started. According to the invention, the original gate building and the drainage hole of the dam are fully utilized, a drainage channel does not need to be additionally arranged, the dam body is not influenced, the pipeline energy loss caused by dam turning (or dam winding) is not needed, the pipeline desilting and desilting operation efficiency is effectively improved, and the desilting cost is greatly reduced due to the repeated use of the device.
一种应用于平板钢闸门的无损过坝排沙方法，包括以下步骤：首先关闭水库检修闸门；在平板钢闸门的中心位置，固定设置闸门对接装置；在平板钢闸门下游侧的闸门对接装置出口端连接过闸控制装置；在过闸控制装置的出口端连接下游排沙装置；关闭过闸控制装置，在平板钢闸门下游侧的闸门对接装置进口端连接上游排沙装置；打开过闸控制装置及下游排沙装置，开始管道清淤作业。本发明充分利用了大坝原有闸门建筑物及泄流洞，不需另外加设泄流通道，不会对坝体本身产生影响，也不需翻坝（或绕坝）造成管道能量损失，有效提高了管道清淤排沙作业效率，装置的可重复性使用也大幅度降低了清淤成本。
