Hydraulic structure

Abstract

The invention discloses a hydraulic structure, which comprises a soil foundation and a water body impermeable and ventilated structure supported by the soil foundation, wherein the water body impermeable and ventilated structure comprises a waterproof ventilated particle layer which is positioned on the soil foundation and has the waterproof ventilated particle diameter of 20 to 3,500 microns, the compactedness of over 90 percent and the thickness of at least 1cm. The impermeable and ventilated structure of the hydraulic structure prevents water leakage depending on the principle of enhancingthe surface tension of the water so as to fulfill the aim of impermeability, and simultaneously reduces the surface tension of gas so as to make the gas easily pass through the waterproof ventilated particle layer. Therefore, the impermeable and ventilated structure has dual functions of impermeability and ventilation. Because the waterproof ventilated particle layer consists of impermeable particles, the hydraulic structure has liquidity, can automatically repair the soil foundation or cracks caused by crustal movement, can be communicated with atmosphere and can effectively improve the ecological environment of the water body.

Description

technical field [0001] The invention relates to a water conservancy facility. Background technique [0002] my country's water resources are particularly scarce, with a total volume of 28 trillion cubic meters and a per capita water resource of only 2,170 cubic meters, which is less than a quarter of the world's average level. It is one of the 13 water-poor countries in the world. In my country, available water sources mainly include river water, freshwater lake water and shallow groundwater. [0003] For surface freshwater resources such as rivers and lakes, water loss is mainly due to evaporation and seepage. According to incomplete statistics, seepage accounts for about 80% of water loss. In the prior art, in order to solve the leakage problem of surface fresh water resources such as lakes, an anti-seepage layer is mainly used. The anti-seepage layer is a structural layer formed by using anti-seepage materials on the bottom and revetment of the artificial lake. In the n...

Problems solved by technology

[0010] The purpose of the present invention is to overcome the poor anti-frost heave damage ability of the water body anti-permeation gas structure of the water conservancy facilities in the prior art, which is easy to produce cracks and displacements, and blocks the upper and lower communication of the ground gas, reduces the oxygen content of the water body, and reduces the For defects such as self-purification function of water body, provide a water conservancy facility that has good anti-permeation effect, strong resistance to frost heave damage, is not easy to produce cracks and displacement, and can be connected to ground air, which can effectively improve the ecological environment of water body
