Temporary transfer method for pressure pipeline under multiple working conditions
The invention relates to a pressure pipeline temporary transferring method for multiple working conditions. A starting point extension pressure well and a terminal point extension pressure well are built at the positions, except the starting point position and the terminal point position, of a part of pressure pipelines needing to be transformed; the starting point expansion pressure well and the terminal point expansion pressure well are communicated through a temporary drainage header pipe, and a water supply and drainage path bypasses the pressure pipeline needing to be transformed; a temporary drainage pipeline and a temporary pump pipeline which can be independently controlled to be opened and closed are arranged between the starting point extension pressure well and the temporary drainage header pipe; and water supply and drainage from the starting point expansion pressure well to the terminal point expansion pressure well are realized through the adjacent drainage pipeline or the adjacent pump pipeline. The pressure cover plate has the advantages that the pressure cover plate can be conveniently detached only by opening the upper-layer well cover, and a maintenance space is arranged below the cover plate according to a normal inspection well, so that personnel can conveniently clean and maintain the pressure cover plate; the overall structure is simple and safe, the flexibility is high, the temporary transfer condition of the pressure pipe when the flow pressure change is large or the surplus water head cannot be accurately calculated can be dealt with, and the regional safety is guaranteed.
本发明涉及一种针对多工况的压力管线临时转输方法，在需改造部分压力管道的起点位置、终点位置之外的现状压力检修井位置处分别建设起点扩建压力井和终点扩建压力井；将起点扩建压力井与终点扩建压力井通过临排总管连通，使给排水路径绕过需改造部分压力管道；在起点扩建压力井与临排总管之间设置可分别独立受控启闭的临排管路和临泵管路；通过临排管路或临泵管路实现自起点扩建压力井至终点扩建压力井的给排水。本发明的优点是：只需打开上层井盖，便可方便拆卸压力盖板，盖板下按正常检查井设置检修空间，方便人员清掏和检修；整体结构简单安全，灵活性强，可应对流量压力变化大或无法准确计算富余水头时的压力管临时转输情况，保证区域安全。
