Abstract

The invention relates to a pneumatic-hydraulic combination type reservoir dredging device, which includes a discharge dam body and a reservoir connected together, and is characterized in that: several gas tanks are arranged on the discharge dam body, and two adjacent gas tanks The tanks are connected together by an air compressor; each of the several gas tanks is connected with a water gas pipeline leading to the bottom of the reservoir, and the end of the water gas pipeline is connected with a sand blowing pipe with a vent hole; A disturbance pipeline with a disturbance reamer is arranged between the two adjacent water gas transmission pipelines. One end of the disturbance pipeline is connected with an inclined water inlet pipe, and the other end is connected with a water outlet at the bottom of the discharge dam body. pipeline; the upper part of the discharge dam body is provided with several sand discharge holes, and the lower part is provided with several sand discharge bottom holes. The invention greatly improves the dredging efficiency, can effectively reduce the energy consumption of the dredging work in the reservoir area, reduces manpower, material and financial resources, and has great practical significance and considerable economic significance.

Description

technical field [0001] The invention relates to a dredging technology for reservoir areas of water conservancy projects, in particular to a pneumatic-hydraulic combined dredging device for reservoirs. Background technique [0002] my country has 98,000 reservoirs of various types, which play an important role in effectively mitigating flood and drought disasters and meeting urban and rural drinking water safety, flood control safety, food security, and energy security. However, my country is also the country with the most serious reservoir siltation. Because the river flow movement is often accompanied by sediment transport, the reservoir siltation has become a worldwide problem. Affected by sedimentation, the average service life of the reservoir is 22 years, which is far from the life of the dam body of at least 100 years. According to statistics, the annual sediment load of the seven major rivers in my country is as high as 2.3 billion tons. Even the Yangtze River has a ...
