Description

Self-priming reservoir river load is removed pipe-line system

Technical field

Self-priming reservoir river load is removed pipe-line system, is mainly used in removing in water conservancy, the hydroelectric project reservoir riverbed, river and the fields such as diversion and diversion and power that year by year silt and dredging increase year by year because of Sediment Siltation.Prolong the engineering life-span by removing, to increase storage capacity and generated energy, to guarantee the unimpeded of river and the landlocked safety of dike protective embankment by removing, to be used for self-priming diversion and the diversion and power construction costs of can suiting measures to local conditions to reduce, to take full advantage of resource.

Background technology

Existing Hydraulic and Hydro-Power Engineering does not also have other better method to solve Problems of Reservoir Sedimentation except adopting the bottom hole for sand flushing design.And bottom hole for sand flushing can only be removed near a small amount of limited silt dam body sand discharge hole, does not reach thorough removing effect, and silt enters and underwater bed is increased and produces many adverse effects.The in addition design of bottom hole for sand flushing, operation, risk are larger, also are unfavorable for the stability of integral dam design.The many engineerings of various reasons do not design bottom hole for sand flushing yet.Because precipitation makes a large amount of silt pour the river reservoir, sluggish flow easily causes silt to sink to bottom of the reservior, river bed in the reservoir, just will inevitably affect engineering operation and application life after this deposition acquires a certain degree.

Mainly by dredge boat, this method of operating cost is high in the at present dredging of channel deposits, the low large tracts of land of efficient is used and is restricted.Therefore have to so just form some riverbed, river and be higher than the landlocked plane of dike protective embankment with the rising of increasing dykes and dams and deal with the riverbed, make dike protective embankment inland when flood, be subject to security threat.

Summary of the invention

Water conservancy, hydroelectric project and river the invention provides a kind of self-priming reservoir river load removing pipe-line system and solve the problems referred to above because of problem and harm that Sediment Siltation brings in order to solve for a long time.The technical measures that the present invention takes are: it is exactly to utilize to connect good closed conduit yarn system that self-priming reservoir river load is removed pipe-line system; The water inlet of pipe-line system is stretched in the reservoir or river of high water level, utilize the reservoir river level to be higher than the formed pressure of difference of pipe-line system delivery port water level, make water in pipeline, produce one by the mode that pours into the diversion activation again and inhale the stream motion, inhale first-class motion by one a closed suction stream pipeline of water introduction pipe delivery port formation in reservoir or river is drawn reservoir, bottom, river silt reaches the purpose of automatic sucking removing, the silt that flows out both can be transported through the filter drainage, and the base area condition also can suit measures to local conditions to stack on the spot or enter downstream river to wash away.

The distinguishing feature of the method is, owing to having adopted an enclosed self-priming suction stream pipeline yarn system, opening conduits system delivery port operating valve (11) can be started working after pouring into diversion by diversion valve (9), and regulate working range by extension (4), close delivery port operating valve (11) and namely quit work, need not any miscellaneous equipment and the energy and silt can be pulled out reservoir, bottom, river.So it is low to consist of cost, the characteristics such as efficient is high, easy construction.

Because its characteristics, a large amount of silts of removing reservoir, river alluvial are no longer high because of cost, the low difficult construction of efficient is subject to puzzled the obstruction.Therefore the invention has the beneficial effects as follows: solved for many years the difficult problem of unsolved reservoir, river load alluvial always and all consequences that alluvial brings.Make Hydraulic and Hydro-Power Engineering no longer because Sediment Siltation is affected, guaranteed that the Hydraulic and Hydro-Power Engineering life-span no longer is subjected to the threat of Sediment Siltation and obtains indefinite prolongation.Remove pipe-line system by self-priming silt and come dredging river, thereby the safety of assurance river dykes and dams and normal shipping guarantee that dike protective embankment inland no longer is subjected to the threat of flood.
