Energy-gathering rotary accelerating silt removal method for long-distance standard-section artesian ditch

Abstract

The invention discloses an energy-gathering rotary accelerating silt removal method for a long-distance standard-section artesian ditch. The method includes the steps of 1, determining the position and the number of energy-gathering rotary accelerating silt removal parts according to the environmental condition of the artesian ditch; 2, arranging an intra-ditch desilting basin in a bottom of the artesian ditch, arranging an extra-ditch desilting basin outside the artesian ditch, arranging energy-gathering cones on the downstream sides of bottom sills of radial gates of a regulating sluice, arranging energy-gathering rotary accelerating water pipelines between the intra-ditch desilting basin and the energy-gathering cones, arranging rotary accelerating water pipe valves on the energy-gathering rotary accelerating water pipelines, communicating the intra-ditch desilting basin to the extra-ditch desilting basin through a silt drawing pipe and arranging a silt drawing pipe valve at the tail end of the silt drawing pipe; and 3, removing silt on the bottom of the ditch. The method has the advantages that on the premise of realizing continuous water transferring and supplying of the long-distance standard-section artesian ditch, the flowing energy of water in the ditch is gathered to remove the silt in the ditch, and the phenomenon that the silt in the ditch is deposited seriously and influences safe operation of water conservancy facilities is prevented.

Description

Technical field [0001] The invention relates to a long-distance standard section artesian canal, in particular to a long-distance standard section artesian canal, which relates to a method for accelerating the cleaning of sediment by concentrating energy and turning. Background technique [0002] With the development of social economy, water consumption for industry and agriculture and domestic water consumption are increasing. The insufficient water supply will seriously restrict the development of the national economy and affect people's normal life. Therefore, the use of long-distance standard section artesian canals to adjust the water balance between water-rich areas and water-deficient areas is an important method used in water conservancy projects. During the uninterrupted operation of the long-distance standard section artesian canal for many years, there will inevitably be the problem of sediment and organic siltation in the channel. The main reasons are as follows: 1. T...

Problems solved by technology

The length of the open flow section of a single long-distance standard-section artesian channel in China has exceeded 1100km. According to preliminary statistics, the amount of sediment entering the channel from the outside of the artesian channel through the dikes on both sides of the artesian channel and the dust in the air along both sides of the channel is thousands or even more. More than 10,000 tons; 3. Harmful pollutants are deposited in the sediment to pollute the water quality: the long-term operation of the open channel with a length of 1100 km will inevitably lead to the deposition of dead bodies of small animals (rats, snakes, fish, frogs, teals) and birds In the sediment at the bottom of the canal, decaying organic matter will pollute the water quality, affecting the quality of water diversion and water supply

Therefore, in order to prevent a large amount of sediment in the canal from affecting the safety of water conservancy facilities and water quality, it is imperative to regularly clean up the sediment and sediment in the long-distance standard cross-section artesian canal, but there are no relevant reports on the removal of sediment and pollution. physical measures
