Abstract

An energy dissipator of a high-fall sluice comprises the sluice and an absorption basin. The sluice comprises a sluice floor and a sluice gate. The absorption basin is arranged on a downstream side of the sluice and comprises a drop wall, an absorption basin floor and an absorption basin tail threshold, and an upstream end face of the absorption basin tail threshold is a slope face. The drop wall, the absorption basin floor and the absorption basin tail threshold are of an integrated structure molded by once casting of concrete. A downstream end of the sluice floor is connected with the drop wall. The energy dissipator of the high-fall sluice is convenient to construct, simple and reasonable in structure, less in investment and good in energy dissipating effect. The prominent advantage of the energy dissipator is that the energy dissipator not only can adapt to riverway deformation with large fall between upstream and downstream due to various reasons such as sand excavation, but also can meet requirements of joint of upstream flow and downstream flow.

Description

A kind of energy dissipator of high drop sluice

Technical field

The utility model relates to that a kind of to adopt sand serious to the river course, the form of energy dissipater when river bed, upstream and downstream drop is big, particularly a kind of energy dissipator of high drop sluice.

Background technology

By the end of in June, 2008, China's sick danger (three, four types) sluice has 2.97 ten thousand, accounts for 72% of national sluice sum.The existence of extensive sick dangerous sluice has influenced the operation of sluice; Injure the flood control safety of water construction things such as dyke; Restricted the sustainable development of national economy; Therefore, file of central authorities in 2011 will advance the dangerous sluice reinforcement of big-and-middle-sized disease to grab as an important process strengthening the construction of irrigation and water conservancy weak link.

But; Ubiquities such as the most of river, Liaoning Province such as the Liaohe River, Qinghe, Pu He are adopted the sand phenomenon and are remained incessant after repeated prohibition; The indiscriminate mining and serious waste river sand of excess; Changed former metastable bed configuration, flow-shape to a great extent, caused the serious incision in local section or whole riverbed, changed and worsened the river gesture, increased the difficulty of sick dangerous sluice reinforcement work.

High drop falls bank formula energy dissipater and washes away and to adopt sand serious to present ubiquitous downstream river course, the upper river alluvial, and the upstream and downstream that forms has the energy dissipater's scheme than the Tai Ho Road drop.

The utility model content

The purpose of the utility model provides a kind of energy dissipator of high drop sluice, a kind ofly rebuilds or energy dissipater's design scheme of the big-and-middle-sized high drop sluice of reinforcement to needing to remove.

The technical scheme that adopts is:

A kind of energy dissipator of high drop sluice comprises sluice and absorption basin; Sluice comprises gate floor and gate, is known technology; Absorption basin places the downstream (for after sluice opens, water flows out a side) of sluice, and absorption basin comprises drop wall, absorption basin base plate and absorption basin tail bank, and the upstream face of absorption basin tail bank is domatic; Drop wall, absorption basin base plate and absorption basin tail bank are the overall structure by the concrete one-time cast-forming; The gate floor downstream is connected with drop wall.

The absorption basin base plate vertically offers a plurality of gutters on the downstream, is equipped with concrete cushion under the absorption basin base plate upstream side diapire, is equipped with hardcore bed, sand cushion and nonwoven layer from top to bottom successively under the diapire of absorption basin base plate downstream.

The drop wall lower end is connected with drop wall and holds up arm and drop wall key-wall.

Absorption basin tail bank has extended the anti-key-wall of washing in a pan vertically downward, and anti-naughty key-wall and absorption basin base plate are the overall structure of concrete one-time cast-forming.

Drop wall is provided with rubber sealing and red copper sealing.

Be provided with horizontal Reynolds protection pad apron and Reynolds protection pad mask in absorption basin tail bank and anti-downstream of washing in a pan key-wall; Reynolds protection pad apron upstream extremity is connected with absorption basin tail bank; Reynolds protection pad mask is connected with the anti-key-wall of washing in a pan, and in Reynolds protection pad apron and Reynolds protection pad mask, uses the jackstone backfill.

Downside at Reynolds protection pad mask is provided with the apron hardcore bed.

The operating principle of the utility model:

Gate 2 is placed on the gate floor 1 through gate slot, starting gate 2, and current are through gate, and hydraulic jump takes place in the drop wall 3 of flowing through on absorption basin base plate 4, and formation is flooded levelling surely through absorption basin tail bank 12 and apron 19 in absorption basin; Gutter 5 is used to lead and oozes, thereby reduces the uplift pressure that produced by the upstream and downstream head difference; Anti-naughty acting as of key-wall 6 fixed the sand, and has erosion control, anti-effect of washing in a pan simultaneously; It is to keep the absorption basin base slab stability and the structural measure that adopts that drop wall is held up arm 7; The skid resistance that act as increase absorption basin base plate of drop wall key-wall 8.Adopt twice sealings (9 and 10) to be used for antiseepage between gate floor and the drop wall, 9 is the rubber sealing, and 10 is the red copper sealing, and its non-deformability is strong.C ₁₀The effect of concrete cushion 11 is to make foundation surface smooth, is convenient to assembling reinforcement in the above, has the effect on protection basis simultaneously.Absorption basin tail bank 12 and absorption basin base plate 4 and the anti-method that adopts integral cast-in-situ between the key-wall 6 of washing in a pan.5 times set from top to bottom hardcore beds 13 of gutter, sand cushion 14 and nonwoven 15 are called loaded filter, and its effect is that band is not walked the grogs in the absorption basin ground, thereby prevents piping and the generation of flowing seepage failures such as soil when permeating current from gutter 5 outflows; Reynolds protection pad mask 16 plays the effect of washing away of preventing; 17 pairs of aprons of apron hardcore bed have reverse filter effect.Jackstone 18 backfills are behind anti-naughty key-wall 6, and most energy washing away apron prevents not disappear in the absorption basin.

The advantage of the utility model is:

The utility model easy construction; Simple and reasonable for structure; Small investment, effect of energy dissipation is good, and maximum characteristics are that it can adapt to owing to the bigger river courses of the upstream and downstream drop that a variety of causes caused such as adopting sand is out of shape; More can satisfy the requirement that the upstream and downstream current are connected, solve the excessive difficult problem that the dangerous sluice reinforcement of the big-and-middle-sized disease in the whole nation is produced of present river course drop.
