In the aspect of accessory facility research of the long-distance water transmission pipeline, the industry scholars do less intensive research with pertinence, and only shallow talk is carried out as one point in the optimized design of the long-distance water transmission pipeline.
In the foreign aspect, the optimization of the pipe diameter starts in the last 60 th century, and with the rapid development of long-distance pipeline water delivery engineering, the economic pipe diameter also goes through a rapid development period. After more than fifty years of research, the optimization algorithm of the economic pipe diameter is widely applied to actual engineering. The main research objects of foreign scholars are also the aspects of pipe diameter selection, hydraulic calculation, water hammer analysis and the like of the long-distance water conveying pipeline. Because the actual situation of the placement and design of the auxiliary well rooms at the location of each project is closely related to the overall background of the project, research in this regard is less and more difficult to be generalized.

Various valve means are provided separately in the well. And the large-caliber pipeline has larger pipe diameter size, so that the traditional integral pipe-wrapped well chamber also has larger size, and the maintenance valve well on the existing long-distance large-caliber double-pipe water conveying pipeline has large occupied area and single function. On the other hand, the large-caliber double-pipe water delivery is laid in parallel, a certain clear distance is reserved for ensuring the running safety of the large-caliber double-pipe water delivery, and the multiple functions of maintenance, air intake and exhaust, bypass and the like on a water delivery pipeline are still arranged like the traditional mode, so that the clear distance between the double pipes is greatly wasted. In addition, the hoisting maintenance of the traditional composite maintenance valve well equipment is also difficult.
