Abstract
The utility model relates to a diversion pier group for adjusting water flow, in particular to a diversion pier group with sector arrangement, which belongs to the field of water conservancy and water transportation engineering construction. The diversion pier group with sector arrangement comprises a plurality of diversion pier groups in sector arrangement. The diversion pier group realizes the purpose of effectively adjusting water flow in approach channels, and providing fine water flow condition for ships to successfully pass a gate region of a downstream approach channel port, thereby adding safety to traveling ships, and reducing cost of devices for adjusting water flow.
Description
Technical field
The utility model relates to a kind of baffle pier group, relates in particular to a kind of baffle pier group of fan-shaped layout.Belong to water conservancy marine traffic engineering building field.
Background technology
Along with building of various water conservancy marine traffic engineerings, having on the river of shipping request, between navigation structure and sluice and generating tail water, generally can be provided with, flood discharge water under the sluice and generating tail water and navigation structure approach channel be separated, to help the on an even keel of boats and ships every the stream dike.But stream and generating tail water flow velocity are bigger because sluice sluices down, can cause disadvantageous navigation condition being that door district, pilotage road junction forms transverse flow speed and backflow flow velocity every stream dike tail.In order to improve navigation condition, provide multiple in the prior art and carried out improved mode, as establishing open channel every stream on the dike, on the stream dike, establish permeable hole and establishing mode such as floating embankment every Liu Diwei.According to research, on the stream dike, establish open channel and easily the water body in the approach channel is caused de-stabilising effect, be unfavorable for navigating.If the form of permeable hole and floating embankment is too complicated, be unfavorable for site operation.The present invention proposes a kind of novel method of improving door district, pilotage road junction navigation condition, through experimental examination, can control the fluidised form in Kou Men district well, subdue the transverse flow speed and the backflow flow velocity in Kou Men district, and construction is simple, and the water body in the approach channel is not had adverse effect.
Summary of the invention
The technical problems to be solved in the utility model just provides a kind of simple baffle pier group that also can better subdue the fan-shaped layout of Kou Men district transverse flow speed and backflow flow velocity that constructs.
The baffle pier group of fan-shaped layout of the present utility model comprises being no less than 2 baffle piers 1 and being certain included angle each other.
Above-mentioned baffle pier 1 is made of pier body 2, pier nose 3 and pier tail 4;
Above-mentioned baffle pier pier body 2 is made of cuboid;
Above-mentioned baffle pier pier nose 3 and pier tail 4 are made of semicylinder or tri-prismoid;
Above-mentioned a plurality of baffle pier pier tails 4 are on straight line 5, and pier body 2 becomes different angles 6 with above-mentioned straight line;
Above-mentioned a plurality of baffle pier pier bodies 2 and above-mentioned straight line angle 6 for acute angle and longshore current to diminishing gradually;
Above-mentioned a plurality of baffle pier length meet the following conditions, and are positioned at the line of the baffle pier pier tail 4 of the upstream baffle pier pier nose 3 adjacent with its downstream, perpendicular to adjacent downstream pier pier body 2.
The utility model has following beneficial effect:
1, utilize the utility model, make by the current every stream dike dike tail to be weakened by the baffle pier group, pilotage road junction door district transverse flow speed and backflow flow velocity are reduced, it is current to be convenient to boats and ships.
2, utilize the utility model, make construction convenient simple, save engineering quantity.
Description of drawings
Fig. 1 is three baffle pier forms of the utility model embodiment;
Fig. 2 is seven baffle pier forms of the utility model embodiment;
Fig. 3 is the baffle pier shape schematic diagram of the utility model embodiment;
Fig. 4 is the another kind of baffle pier shape schematic diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is elaborated.
As shown in Figure 1, the utility model embodiment comprises a plurality of angled baffle piers.
As shown in Figure 2, be a kind of form of the present utility model, comprise seven baffle piers.The angle 5 that is from upstream to each baffle pier 1 of downstream and straight line 6 is respectively 55 °, and 50 °, 45 °, 40 °, 35 °, 20 °, 15 °.
As shown in Figure 3, baffle pier 1 of the present utility model is made of pier body 2, pier nose 3 and pier tail 4.
As shown in Figure 4, the another kind of form of baffle pier 1 of the present utility model, pier nose 3 and pier tail 4 are made of tri-prismoid.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above is only own for concrete embodiment of the present utility model; be not limited to the utility model; all within claim of the present utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
