Embodiment Construction
[0015] The invention will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0016] Such as figure 1 As shown, a convex bank water diversion and anti-silting system includes a drainage channel and a diversion wall 2 located on the convex bank 102 of the river channel. One end of the drainage channel is provided with a water intake 6, and the water intake 6 flows against the flow direction of the river channel 1. Arrangement, the other end of the drainage channel is provided with several guide sand ridges 3.
[0017] The length of the diversion wall 2 is twice the length of the water intake 6 .
[0018] The height of the front 1 / 3 part of the diversion wall 2 is the design flood level, and the rear 2 / 3 part of the diversion wall 2 is lower than the front 1 / 3 part of the diversion wall 2 .
[0019] The several sand guide ridges 3 are linear sand guide ridges, and each sand guide ridge 3 is arranged parallel to each other. The ...

The invention discloses a water diversion and silt prevention system for a convex bank. The water diversion and silt prevention system comprises a water guiding channel and a guiding wall which are arranged at the convex bank of a riverway, one end of the water guiding channel is provided with a water taking opening, the water taking opening is arranged inversely according to the flowing direction, the other end of the water guiding channel is provided with a plurality of sand guiding sills, the water taking opening is 2-4 times longer than the guiding wall, a front one third portion of the height of the guiding wall is a design flood level, the rear two thirds portion of the guiding wall is lower than the front one third portion of the guide wall, the sand guiding sills are straight line sand guiding sills, the sand guiding sills are parallel to one another, an inclination angle of 35-45 degrees is formed between the sand guiding sills and the flowing direction of the riverway, the length of the sand guiding sills is one second of the width of the water taking opening, and the number of the sand guiding sills is 3-5. The water diversion and silt prevention system is simple in structure, the silt preventing efficiency is good, and the water diversion is guaranteed.
Description
technical field [0001] The invention relates to a water diversion and anti-silting system, in particular to a convex bank water diversion and anti-silting system. Background technique [0002] Reliable water quantity, good water quality, and reasonable cost are the primary tasks to be solved by water intake projects. Therefore, the layout of water intake buildings is the key to the success of water intake projects. The layout of water intake structures is affected by many factors, and its hydraulic problems are mainly manifested in the degree of guarantee of water intake, sedimentation and water flow, etc. These problems have a great impact on the safe operation of water intake structures. In order to facilitate water diversion and prevent sediment from entering the channel, the water intake should generally be set on the concave bank of the curved river channel. When the concave bank has no suitable location, it can also be built in the straight river section. As we all kn...
