Wherein, through addding additional strengthening 2, avoid under the macroseism effect, the probably emergence of silt basin 10 pool wall root department is sheared and crooked destruction, leads to silt basin 10 probably to take place the danger of slip unstability and toppling for can be when rationally saving the cost, effectively guarantee macroseism district silt basin 10's antidetonation safety.
The dam that this application embodiment provided, dam include flood discharge sand-pulling floodgate and as above-mentioned desilting pond, and optional, flood discharge sand-pulling floodgate sets up in the low reaches of dam, and is located desilting pond one side, when meetting rainy season or a large amount of flood and being difficult to the interception, draws the sand-pulling floodgate through opening the flood discharge and carries out the flood discharge. The sand basin comprises a sand basin body, a water inlet and a water outlet; the desilting basin body comprises a desilting cavity, the desilting cavity is defined by a plurality of side walls and the bottom of the desilting basin body together, a water inlet is communicated with a water source at the upstream of a dam, and a water outlet is communicated with a gradual change section of a power generation water intake of a hydropower station; wherein, still include the additional strengthening, the additional strengthening sets up on at least one of side wall and the bottom of the pool along rivers one side. Specifically, the reinforcing structure is arranged on the side wall along one side of the water flow, namely on the long side wall of the sand settling cavity along one side of the water flow, so that the stability of the side wall of the sand settling cavity along one side of the water flow is improved; or the reinforcing structure is arranged on the pool bottom, so that the stability of the pool bottom structure is improved; or for the stability of better improvement whole structure, set up additional strengthening respectively on the side wall and the bottom of the pool along rivers one side, avoid under the macroseism effect, desilting pond wall root department probably takes place to cut and crooked destruction, leads to the desilting pond probably to take place the danger of slip unstability and toppling for can be when rationally saving the cost, effectively guarantee the antidetonation safety in macroseism district desilting pond.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments can still be modified, or the technical features of the partial or full cavities therein can be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
