Aeration design method of rubber dam project and device thereof

Abstract

The invention discloses an aeration design method of a rubber dam project and a device thereof; the characteristics are as follows: the bottom of the upper stream of the rubber dam is provided with a main aeration pipeline along the length direction of the dam body, meanwhile, the main aeration pipeline is provided with a plurality of holes along the length direction of the main aeration pipeline, wherein, each hole is communicated with an aeration branch pipe whose pipe opening faces towards the lower stream, the pipe opening of the aeration branch pipe is connected with an aeration hole plate, one end of the main aeration pipeline is arranged as a sealed plug, the other end of the main aeration pipeline is communicated with a blower which is located at shore or a control room. The advantages of the invention are as follows: the aeration device with low energy consumption can not be blocked, is practical and simple, and can effectively improve the state of water flow and water quality at the bottom for the upper stream of the rubber dam.

Description

Technical field [0001] The invention relates to an aeration design and device, in particular to the aeration design and device of a rubber dam project. Background technique [0002] At present, rubber dams have been widely used as hydraulic structures to increase the water head of the river. In some engineering constructions, due to the high weir of the rubber dam and the high water storage depth, the water flow near the bottom of the upper reaches of the rubber dam is stored for a long time. It does not flow and presents an anaerobic state, and it is easy to cause deterioration of water quality. There is no design or device specifically designed to solve this problem in the rubber dam projects currently built. Summary of the invention [0003] The purpose of the present invention is to provide an aeration design method and device for rubber dam engineering, which can mobilize the water flow at the bottom upstream of the rubber dam through the aeration device, thereby increasing t...

Problems solved by technology

[0002] At present, the rubber dam has been widely used as a hydraulic structure to increase the water head of the river. In some engineering constructions, due to the high weir body of the rubber dam and the high water storage depth, the water near the bottom of the upstream of the rubber dam has been stored for a long time. It does not flow and is in an anaerobic state, which is very prone to water quality deterioration. At present, none of the rubber dam projects built has a design or device specially designed to solve this problem.
