Abstract

The invention discloses a wall surface structure of a vibration absorbing and sound attenuating stilling pond and relates to the noise-reducing techniques of stilling ponds. The stilling ponds existing in water resources and hydropower engineering widely are indispensable energy-dissipating buildings. The side wall of the stilling pond is of a hollow structure, a panel is arranged on the side wallof the side, close to water, of the stilling pond, and the panel is an elastic board which can transfer vibration and noise generated by a water body. The hollow side wall structure of the stilling pond is filled with granular mixtures which are graded sand, that is, the grain sizes of the sand comprise coarse sand, medium sand and fine sand. The graded sand can absorb and dissipate vibration andnoise transferred by the elastic panel. The wall surface structure of the vibration absorbing and sound attenuating stilling pond can weaken noise generated when the stilling pond eliminates flood discharge and energy dissipation.

Description

technical field [0001] The invention relates to a noise reduction technology for a stilling pond, in particular to a wall surface structure of a vibration-absorbing and noise-absorbing and stilling pond. Background technique [0002] Xiangjiaba Hydropower Station is a large-scale hydropower station located on the Jinsha River. Due to its proximity to the county seat, the huge flood discharge power will cause flood discharge noise after the power station is in operation. The flood discharge noise further induces the vibration of residential buildings in the county town, which brings about environmental noise problems. , have an impact on the lives of the surrounding residents. China's hydropower is rich in the southwest region, and the hydropower stations to be built in the future will mainly be in the southwest region. For hydropower stations built in the southwestern alpine and valley areas in the future, there may be villages, towns, and residential areas near the site; o...
