Problems solved by technology
[0003] However, the above-mentioned invention has a disadvantage in that, although the over-current protection structure can effectively block the flow of gravel in Hanoi to the downstream, after a long time, a large amount of gravel will accumulate in the over-current protection structure, which is likely to occur in a large amount. After the accumulation, the over-current protection structure will be blocked, causing the water flow to fail to flow normally, and what's more, the over-current protection structure will be washed away
Due to the turbulent water flow at the overflow slag collection weir, it is very dangerous to salvage and clean up manually. If you drive a salvage vehicle to salvage, it is easy to cause landslides due to the soft soil on the shore

Loading cages, the river bank is provided with lifting components that drive the loading cages to move in the vertical direction, the bottom of the river is laid with a flat platform, the protective screen is provided with a translational screen, and the protective screen is provided with a drive Assemblies, the river body is located at the upstream end of the protective net plate is provided with a barrier net plate, and the river bank is provided with a moving assembly for driving the barrier net plate to lift in the vertical direction. The advantages of cleaning and reducing the difficulty of salvage and the risk factor.
Description
technical field [0001] The invention relates to the technical field of design and construction of water conservancy and hydropower engineering buildings, in particular to an overflow slag collection weir for water conservancy and hydropower engineering and a construction method thereof. Background technique [0002] At present, in water conservancy and hydropower projects, the excavation of the dam abutment slope or the river bank slope, the current general technology is to set up a slag collection platform at the foot of the river bank slope to collect gravel, but due to the steep slope, the gravel collected by the slag collection platform Limited, the excavated gravel will enter the river channel and be carried downstream by the water flow, causing river channel siltation and soil erosion. At the same time, it is difficult to collect slag in the construction of the slope toe. Therefore, the Chinese patent with the authorized notification number CN104947630B discloses an ov...
