Description
Technical field
The utility model relates to water conservancy equipment field, especially relates to the Accrete clearing device of reservoir in a kind of hydraulic engineering.
Background technology
Water conservancy reservoir is owing to having tackled water, and a large amount of mud that water is carried secretly can deposit to bottom reservoir, cause Reservoir Water Quality to worsen, volume reducing, impact generating etc.The reservoir desilting mode of current routine is as follows:
Hydraulic method desilting mainly refers to and adopts hydraulic method dredging reservoir.This method is commonly used the most, and is just considered among major project by designing unit at the beginning of reservoir is built.Its form has so several: with discharging by density current, establish flushing sluice sand surfing, use bottom outlet sand discharge.The advantage of hydraulic method is: desilting engineering does not need emptying reservoir in advance, does not also need out of service.In desilting process, reservoir can run as usual.The shortcoming of the method is: dredging can only carry out limited control to digging silt, and between flood period, all dividing of having excavated may be silted up again.Adopt and carry out digging silt in this way and need mud conveying arrangement and rickyard.
Therefore, drainage system must be pre-set in deposit.Normally effective by waterpower sand surfing method sand discharge, but the shortcoming of these methods to be water consumption large, the refilling amount of reservoir must be ensured in addition.
Dry desilting method as its name suggests, carries out desilting exactly after being emptied completely by reservoir.And this method more disadvantages than advantages.The method advantage: be easy to grasp desilting side's amount (cheat the end as seen, also accurately can understand the desilting amount of side slope).The alluvial material removed can directly be transported and stack., only there is the risk that can not estimate in shortcoming: this dredging method itself does not have drawback, when raining, site machinery device cannot operate; Be difficult to the sand discharge speed estimating mud depths, this can cause the uncertainty of commencement of works time; In whole desilting process, reservoir is required out of service.This method is suitable for the special small reservoir of indivedual condition.
When hydrocone type desilting refers to that hydrocone type discharge culvert works, first get rid of inner air tube, make to form vacuum in pipe, now culvert pipe plays siphonage, makes the husky top rising to culvert pipe from culvert pipe import of the water of reservoir, thus flows out to the outlet of downstream culvert pipe continually.Hydrocone type desilting is generally designed to the form of discharge culvert.The advantage of siphon dredging device (hydraulic dredging device) is: do not need emptying reservoir, need not aim at desilting water loss, and desilting does not limit by water season, can irrigate long-term sand discharge in conjunction with each season.Shortcoming is: rely on water levels of upstream and downstream difference to determine the size of output flow, desilting limit certain limit before dam, and water consumption is large, this method is applicable to the reservoir of larger height of dam.
Lateral erosion utilizes high beach deep trouth form specific to dead storehouse, relies on strong mass erosion and sluicing effect to break silt beach and move from defeated.Its specific practice is first riverbed or the exit or entrance of a clitch, tributary, reservoir area in storehouse, if weir (lock) dash, cuts irrigation channel water in the channel or pipeline of storehouse Zhou Xiujian, occupies a commanding position, carry out erosion to silt beach.Lateral erosion ancillary works comprises three parts: one is water intake facilities, principal mode has weir (lock) or water lifting machinery, its role is to heading up, meets the flow required for erosion, two is water transfer facility, general type has channel, open channel or pipeline, its role is to conveying water and flow to storehouse to be rushed section, three is rush beach facility, mainly comprise discharge opening and afflux groove, its role is in a planned way distribute current in water transfer facility and be directed to surface, silt beach, drawing silt in order to rushing beach.
Beach method desilting is rushed in diversion, and beach is rushed in diversion, and its essence is exactly the sedimentation formation utilizing height beach, reservoir area deep trouth, cuts irrigation channel water in the channel of approach along storehouse Zhou Xiujian, increases streaming potential artificially, and dependence mass erosion and sluicing effect are carried out destruction to silt beach and defeatedly to be moved.
In medium and small reservoirs, carry out diversion rush beach, first must possess following condition:
(1) chance that emptying reservoir or low water stage are used will be had.Fully expose to enable beach face;
(2) hole at the bottom of lower sand discharge to be had;
(3) certain clear water base flow to be had;
(4) preferably there is the condition of muddy water warping in downstream, and outbound muddy water and silt can fully be utilized.
But current desilting equipment Problems existing is that desilting efficiency data is low, affect the normal work in power station, water consumption is large.
