The utility model belongs to the technical field of
hydraulic engineering, and particularly relates to a diversion tunnel structure for
hydraulic engineering, which comprises a bottom plate, side plates symmetrically arranged on the upper surface of the bottom plate and a cover plate arranged on the two groups of side plates, a fence is fixed on the upper surface of the bottom plate, a buffer component is arranged on the bottom plate, and the buffer component is fixedly arranged on the bottom plate. The buffering
assembly comprises a first baffle, a second baffle, a third baffle and a fourth baffle which are sequentially fixed to the upper surface of the bottom plate, the heights of the first baffle, the second baffle, the third baffle and the fourth baffle are sequentially increased, the whole buffering
assembly is of a stepped structural design, and drainage grooves are formed in the surfaces of the second baffle, the third baffle and the fourth baffle correspondingly. By arranging the buffer
assembly, the
water flow speed can be reduced, and the
water flow pressure can be dispersed, so that the influence of flood on a downstream area is relieved to a certain extent, the situation that the tunnel collapses or internal components of the tunnel are destroyed due to overlarge
water flow storage potential is avoided, the using effect of the device is improved, and the actual using requirement is met.
