Abstract

The present invention relates to the clear husky river double flute hardening riverbed exchanges in a kind of river dredging, especially the Yellow River to arrhea clear husky device.Now illustrate as an example：" change its course the Yellow River " along existing river or at all times in Xiaolangdi Project On The Yellow River downstream and builds up double flute paralleling or branch's steel reinforced concrete hardening riverbed, each riverbed inlet is equipped with control sluice gate, riverbed is equipped with settling pit every suitable distance and bottom is equipped with the Multi-functional ink storage dam of scouring sluice, and channel is equipped with logical ship, water transfer gate between two riverbeds；When necessary clear husky, dam bottom scouring sluice is opened one by one from husky destination storage dam upstream is transported, and silt is suppressed flow with river bed and rushed to the husky destination in downstream, and the Zhi Heliu is shut down after washing down, and river water imports other hardening riverbeds, and being allowed to dry water can clear husky shield river；Such same method exchange is arrheaed, remaining riverbed also can be clear husky, convenient and practical.

Description

Clear husky device is arrheaed in river double flute hardening riverbed exchange

The present invention relates to a kind of river double flute hardening riverbed exchanges to arrhea clear husky device for technical field.

The large and medium-sized river of background technology and reservoir, especially the Yellow River, the big stream of water is anxious, and silt content is high, and sedimentation is serious, It removes difficulties, the security risks such as " hanging river " phenomenon even occur in middle and lower reaches.

To solve this problem, it is common practice to largely build reservoir in Upper-middle Reaches of The Yellow River, with water storage sediment trapping, flood control is cut Stream, truly has huge produce effects.But long-term a large amount of sedimentation bottom storehouses, increase year by year, and storage capacity is reduced, and seriously affect reservoir and use the longevity Life.If bottom storehouse desilting can be agitated and be stired and make muddy by effective means (such as boat-carrying giant, vibrating head, vibration rake etc.), or set Scouring sluice is set, silt is made to be discharged downstream with river water, can effectively extend reservoir normal service life, but lower spoil disposal sand should be such as where It sets？Recently it learns, inland river, outer river exchange the clear sand that shuts off when Gu repaiies Dujiang weir annual repairs, that is, block Wai Jiang, and water walks inland river, cleaning Outer river sand mud；Vice versa blocks interior river and walks outer river, the practicable old method such as cleaning inland river silt, new to the present invention The feasibility of technical solution, novelty, creativeness, practicability provide strong support and foundation.Refer in April, 2018 distribution Total 445th phase modern ancient legend China Super Engineering revealed secrets, related Dujiang weir inland river, outer river exchange shut off clear husky page 25 and Page totally 8 of the attached drawing of page 23 and full text.

Invention content arrheas clear husky device the task of the present invention is to provide a kind of river double flute hardening riverbed exchange, it It effectively far can send the silt that upstream is discharged into the place needed to downstream, be benefited for society.

The object of the present invention is achieved like this：Now illustrate as an example.Such as in the Yellow River sections Yi Xuan Xiaolangdi Project On The Yellow River Downstream, along existing river, (or the practical circuit that " changes its course the Yellow River " at all times is one as entered Huaihe River circuit along areas formerly flooded by the Huanghe River at the fried mouth of Huayuankou River) using deep naughty beach, the low scientific methods such as dam of making increase reservoir storage, desilting amount, the amount of drainning off floodwaters, build up two slots (or more) reinforcing bar is mixed Xtah Crude Clay structure hardens riverbed parallel or branch, each irrigation channel water enter sea；Each riverbed inlet connects and controls sluice gate on dam body, in riverbed Firm firm Multi-functional ink storage dam is had every suitable distance；Bed bottom is equipped with settling pit before dam and behind dam；Dam body lower part is equipped with row Husky aperture and scouring sluice (dam body waist both sides can be provided with discharge water power generation or the dewatering orifice irrigated by lifting water to a higher level with a water pump, etc. and gate, above dam body in Between baltimore groove can lead to special amphibious trackless electricity ship), dam crest bridge formation be two sides channel；Riverbank leads to the appropriate water level of lateral surface Place connects equipped with the remote defeated pipeline of appropriate water supply of drainning off floodwaters and nearby drains river；Two channels between riverbed are equipped with logical ship, water transfer gate.

When the suitable drain time husky clearly in riverbed, upper pond or hardening riverbed need clear beach volleyball to become silted up, it is optional downstream along the river Nearby need reinforce river levee, fill out hole build up fields or at river sand building materials etc. be short distance point of delivery, herein, storage dam scouring sluice should not It opens, opens its upstream dam body scouring sluice successively, silt will suppress flow by river bed and rush at downstream；Wait for silt water transport to mesh Ground, after completing upstream sand discharge task, close hardening river inlet and control sluice gate, river water imports other hardening riverbeds, is allowed to dry Clear Shahe bed river water, will can not wash down silt and remove disembarkation in destination silt and its upstream settling pit.Riverbed or equipment dimension After shield maintenance, you can open control sluice gate and discharge water, restore normal river and supply water.

If you need to clear up other riverbed silts, same method can also see exchange and arrhea clear husky work in fact, convenient and practical.

If you need to logical ship or adjustment water between adjacent two riverbed, you can open channel gate between two riverbeds, complete to lead to ship or tune The tasks such as water.

Description of the drawings：The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Fig. 1 is according to specific device schematic diagram proposed by the present invention.

Specific implementation mode：The device installs at least two control sluice gates [1], each gate on main river reservoir dam [1] hardening riverbed [2] is had after, two adjacent riverbed [2] intermediate channels are equipped with logical ship, water transfer gate [3], and each riverbed [2] is interior Equipped with settling pit [4] and Multi-functional ink storage dam [5], dam [5] bottom is equipped with sand discharge hole, and gate is housed.

Riverbed [2] control sluice gate [1] is opened, river water flows to river emptying into the sea, two rivers along riverbed [2], settling pit [4], dam [5] Channel gate [3] can be opened and closed according to need between bed [2].

When upper pond or hardening riverbed [2] need clear husky, downstream sediment conveying ground is first selected, dam [5] should not open herein Scouring sluice, opens fill scouring sluice under its upstream dam [5] successively, and silt will be suppressed flow and rush at downstream；Wait for that silt rushes Only to after destination settling pit [4], you can shut down gate [1], river water imports other riverbeds [2], can will be transported after being allowed to dry water Residual silt removes disembarkation in ground silt and its upstream settling pit [4], and can safeguard riverbed and facility；Throttle valve after completion task [1] it discharges water, river can normal use.When remaining riverbed [2] also needs clear sand, clear husky shield river can be also realized with same method, it is high Effect is reliable.

If you need to logical ship or adjustment water, channel gate [3] is removed, you can use.
