Background

In the field of hydraulic and hydroelectric engineering, open channel diversion is a relatively common diversion mode, and is suitable for diversion when hydraulic engineering is built on large rivers in open areas of plain. The open channel diversion has the characteristics of large overcurrent flow, high overcurrent flow speed and the like. The stability of the side slope and the scouring of the canal bottom are the most important engineering problems when the open channel overflows, especially when flood is encountered, and the consequences are very serious once the problems occur. Therefore, the protection of the side slope and the canal bottom of the open channel is very important.

However, the construction of the hinge row generally adopts an underwater sinking technology, and the size and weight of the hinge unit are not enough to resist large-flow and high-flow-rate flood, and are not suitable for protecting diversion open channels. Moreover, the existing hinge row technology mostly adopts the mode of connecting the embedded bars and the U-shaped rings, the connection strength is obviously insufficient, the fracture is easy to occur, and the hinge row technology is also not suitable for the diversion open channel protection. Based on the background, combine the advantage and disadvantage of current side slope safeguard measure, this patent provides an assembled open channel protection machanism, can adapt to rivers and wash away at the bottom of the canal and side slope, simple structure, the protection effect is good, the mechanized construction of being convenient for simultaneously.
