Abstract
The utility model discloses a rectifying structure for lateral drainage, wherein one side of a main stream channel is provided with a water intake, the water intake is internally provided with a pump station and a water gate forebay which are parallel to each other, a partition wall is arranged between the pump station and the water gate forebay, the water gate forebay is also internally provided with two stream guiding piers, and the stream guiding piers are parallel to the partition wall. The bottoms of the two stream guiding piers are both fixed on a same bottom plate to form a U-shaped structure. The rectifying structure can partition the wall end to stream to flow around, and force the stream to turn to reduce backflow at the partition wall. The distance between the stream guiding piers and the distance between the stream guiding piers and the partition wall are determined according to the distribution of the backflow area. For buildings with lateral water diversion, the rectifying structure improves the stream flowing state during lateral drainage, improves the drainage efficiency, and simultaneously lightens the damage of the stream on downstream buildings and stream channels.
Description
Technical field
The utility model relates to a kind of diversion rectifier structure, specifically relates to a kind of flow-shape when improving the drainage of sluice side direction, increases the hydro-structure of lateral opening lock flow.
Background technology
Because the restriction of conditions such as landform, the hydrology can't be adopted under the situation of forward water inlet arrangement form, the side direction diversion often becomes a kind of alternative arrangement form.But owing to be subjected to The Effect of Inertia Force, current are easy to produce and reflux and whirlpool in the forebay of side direction drainage, if do not take the rectification measure, tend to influence the efficient of drainage, and bad flow-shape easily produces some destructions to downstream building, river course simultaneously.Supply water or engineering such as irrigation in often adopt the be arranged side by side mode of diversion of pump lock, separate with partition wall between the pump lock.When come flow path direction by pump side to the lock side or when opposite, the drainage of sluice side direction easily produces the recirculating zone at the lateral opening place near partition wall owing to be subjected to blocking of partition wall, influences the lateral opening drainage of sluice, produced simultaneously whirlpool easily causes beach face and washes away.Therefore the fluidised form of taking rationally economic engineering measure to improve current is necessary.
The utility model content
The technical problems to be solved in the utility model provides a kind of rectifier structure of flow-shape when being used to adjust the side direction drainage, can cut apart the wall end and stream, and forces flow direction-changing to subdue the backflow at partition wall place.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of rectifier structure of side direction drainage, side at main stem is provided with intake, be provided with side by side pumping plant and sluice forebay in the intake, be provided with partition wall between pumping plant and the sluice forebay, also be provided with two water conservancy diversion piers in the described sluice forebay, the water conservancy diversion pier parallels with described partition wall.
The bottom of described two water conservancy diversion piers all is fixed on the same base plate, forms the U-shaped structure.
Described water conservancy diversion pier is a reinforced concrete structure.
The pier nose slyness of described water conservancy diversion pier is smooth-going.
On the one side near main stem, the pier nose of described water conservancy diversion pier is concordant with the end of partition wall.
The beneficial effects of the utility model are embodied in: rectifier structure of the present utility model can be cut apart the wall end and stream, and forces flow direction-changing to subdue the backflow at partition wall place.The distance of the spacing between the water conservancy diversion pier and water conservancy diversion pier and partition wall is determined according to the distribution of recirculating zone.For the side direction water diverting structure, the flow-shape when having improved the side direction drainage has improved the efficient of drainage, alleviates the destruction of current to downstream building and river course simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the plane structure schematic diagram of the utility model rectifier structure;
Fig. 2 is the facade structures schematic diagram of the utility model rectifier structure;
Among the figure: 1, main stem, 2, intake, 3, the water conservancy diversion pier, 31, pier nose,
4, sluice forebay, 5, partition wall, 6, pumping plant, 7, base plate, 8, the water surface.
The specific embodiment
As shown in Figure 1 and Figure 2, side at main stem 1 is provided with intake 2, be provided with side by side pumping plant 6 and sluice forebay 4 in the intake 2, be provided with partition wall 5 between pumping plant 6 and the sluice forebay 4, the utility model rectifier structure is to be provided with two water conservancy diversion piers 3 in sluice forebay 4, and water conservancy diversion pier 3 and partition wall 5 parallel and be arranged on the side near partition wall.Article two, the bottom of water conservancy diversion pier 3 all is fixed on the same base plate 7, and water conservancy diversion pier 3 is rigidly connected with base plate 7, forms U-shaped structure (as shown in Figure 2).Water conservancy diversion pier 3 is reinforced concrete structure with base plate 7.Generally speaking, base plate 7 can be arranged on the natural ground.On the one side near main stem 1, the pier nose 31 of water conservancy diversion pier is concordant substantially with the end of partition wall 5.The pier nose 31 of water conservancy diversion pier is designed to slick and sly smooth-going shape, so that gently guide current.
The utility model is provided with U type flow-guiding structure (being made up of base plate and water conservancy diversion pier) in the partition wall side of side direction drainage building (sluice) forebay along the drainage direction, can cut apart the wall end and stream, and forces flow direction-changing to subdue the backflow at partition wall place.The flow-shape of water inlet when the utility model is used to improve the drainage of sluice side direction increases lateral opening lock flow.The layout form of this rectifier structure (distance of the spacing between the water conservancy diversion pier and water conservancy diversion pier and partition wall) can be determined according to the distribution of recirculating zone; The base plate plane size is put definite according to the water conservancy diversion mop on it; The thickness of water conservancy diversion pier and base plate is then determined according to the requirement of strength of structure.The height of water conservancy diversion pier determines that according to water level the top of water conservancy diversion pier 3 should be higher than the water surface 8.The utility model has improved the efficient of drainage, alleviates the destruction of current to building and river course simultaneously, is applicable to engineerings such as water supply that intake and main stem be the pump lock of 90 ° of left and right sides angles of cut and be arranged in juxtaposition, irrigation.
