In the prior art, the water facing surface of the dam body 1 is only provided with the concrete wave wall 2, and as the earth-rock dam is loose in material and low in impact resistance, especially when flood season comes, the erosion effect of waves, rainwater and river water flow can possibly cause the damage of the concrete wave wall 2 on the water facing surface of the earth-rock dam, and the flow splitting assembly 6 can split the erosion of the water flow and reduce the erosion force of the water flow on the concrete wave wall 2; the buffer component 7 can buffer the water flow to reduce the impact force of the water flow, thereby improving the water flow scouring resistance of the dam body 1.
Referring to fig. 1 and 2, a plurality of diversion ports 3 are formed in the position, close to the bottom, of the flow facing surface of the concrete wave wall 2, a plurality of diversion trenches 4 are formed in the position, close to the bottom, of the flow facing surface of the concrete wave wall 2, a plurality of water outlets 5 are formed in the position, above the flow facing surface of the concrete wave wall 2, of one end of each diversion port 3 is communicated with each diversion trench 4, and the other end of each diversion trench 4 is communicated with each water outlet 5. The water flow enters the diversion trench 4 from the diversion port 3 and flows out from the water outlet 5 through the diversion trench 4, so that the water flow of the concrete wave wall 2 is buffered.
Referring to fig. 1 and 2, in order to realize the diverting effect to the water flow, the diverting assembly 6 includes a plurality of diverting strips 61, and the diverting strips 61 are integrally poured with the concrete wave wall 2, and when the water flow flushes the concrete wave wall 2, the diverting strips 61 can partially block and divert the water flow, thereby reducing the flushing of the water flow to the concrete wave wall 2, and the upstream surface of the diverting strips 61 is set into an arc shape with concave, so that the impact of the water flow to the diverting strips 61 can be effectively buffered.
When the water flow arrives, the water flow contacts with the lower part of the dam body 1, so the bottom of the concrete wave wall 2 is impacted by the water flow first. Referring to fig. 1 and 2, a multistage landing 71 is arranged at the bottom of a concrete wave wall 2, a diversion opening 3 is formed on the upstream surface of the landing 71, the upstream surface of the landing 71 is arranged into an inward concave arc shape, when water flow arrives, the landing 71 can block part of the water flow first, the impact force of the water flow and the concrete wave wall 2 is reduced, the water flow impacting the landing 71 can change direction along the arc surface of the landing 71, part of the water flow enters the diversion opening 3 for buffering, part of the water flow changes the travelling direction and the part of kinetic energy of the water flow at the rear are offset.
The side wall slope of general dykes and dams sets up, has certain buffering effect, and when rivers are great, probably because of the inclined plane buffering effect is certain, still there is rivers to splash dykes and dams body 1 top along the side wall of slope, and with reference to fig. 1 and 2, dykes and dams body 1 upstream face sets up the cambered surface of indent, has improved dykes and dams body 1 lateral wall's ability that water current erodees.

when water flow arrives, part of water flow is intercepted by the terrace 71 at the bottom of the concrete wave wall 2, part of water flow enters the diversion trench 4 in the concrete wave wall 2 from the diversion opening 3 on the terrace 71 and then flows out from the water outlet 5, so that the impact of water flow on the concrete wave wall 2 can be effectively reduced. When the water flow passes through the terrace 71, the diversion strips 61 integrally cast on the concrete wave wall 2 divert the rest water flow after intercepting part of the water flow, thereby reducing the scouring force of the water flow on the concrete wave wall 2.
In order to avoid deformation of the structure of the dam body 1 caused by long-time impact of water flow, a plurality of reinforcing piles 8 are poured into the dam body 1, and the upper parts of the reinforcing piles 8 are connected into a whole through a cross beam 9 poured together with the reinforcing piles 8, so that the stability of the dam body 1 is improved.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
