Compound continuous stepped spillway and implementation method thereof
The invention discloses a compound continuous stepped spillway and further discloses an implementation method of the compound continuous stepped spillway. The compound continuous stepped spillway comprises a flood inlet mechanism and a flood overflow mechanism, the water outlet end of the flood inlet mechanism is connected with the flood overflow mechanism, and a plurality of square water passinggrooves are formed in the bottom end of an arc-shaped gate, so that when the flood discharge water flow is large, a rotating motor is not started, the square water passing grooves are directly used for draining water, water flow can sequentially pass through a plurality of check blocks and buffer cushion blocks to be buffered and unloaded, meanwhile, the square water passing grooves are used for compressing the water flow with the too large flow and the too fast flow, and the situation that the water flow with the too large flow is directly drained into a spillway to cause local damage to thespillway is avoided; and after the water flow enters the flood overflow side wall, the water flow firstly flows into a first-stage energy dissipation groove of an upper-layer main step, primary energydissipation is carried out, part of the water flow is buffered through a buffer groove when flowing through a high tail sill, the energy dissipation position and the aeration corrosion reduction position are advanced to the maximum extent, and cavitation damage to the front portion of the step in the flood discharge process is advantageously avoided.
本发明公开了一种复式连续阶梯溢洪道，还公开了一种复式连续阶梯溢洪道的实施方法，其包括进洪机构和溢洪机构，进洪机构的出水端连接溢洪机构，在弧形闸门的底端开设有若干个方形通水槽，使得在泄洪水流流量较大时，不启动旋转电机直接利用方形通水槽排水，水流可以依次经过多重挡块和缓冲垫块进行缓冲和卸能，同时利用方形通水槽将流量过大和过快的水流进行压缩，避免水流流量过大直接排入溢洪道中对其造成局部损坏，水流在进入到溢洪侧墙中后，先流入到上层主阶梯的一级消能槽中进行初步消能，部分水流流经高尾坎时经缓冲槽进行缓冲处理，最大限度将消能和掺气减蚀位置提前，有利于避免泄洪过程中阶梯前部的空蚀破坏。
