Description
Technical field
The utility model relates to a kind of sediment trapping bank structures for power plant building.
Background technique
Conventional high concentration of sediment river channel power plant building is that protection hydraulic turbine operation is normal, usually in workshop upstream arrangement sediment trapping
Bank, and silt is drained using spillway.For improve sediment trapping bank drawing Sha Xiaoguo, sediment trapping bank generally towards spillway skew back to
Arrangement.When meeting high concentration of sediment in actual motion, it is desirable that sediment trapping bank height is higher so as to sufficiently stop silt, but for mud
The river that husky content is underestimated, by silt, the side of draining is very wise move as early as possible.
Therefore, the structural layout characteristics of power plant building are made full use of, sediment trapping bank structure of the optimization for power plant building makes it
The effect for increasing guide silt is necessary.
Utility model content
In order to solve the above-mentioned technical problem, the application proposes that a kind of sediment trapping bank structure for power plant building, purpose exist
Solve the problems, such as high concentration of sediment river channel power plant building sand discharge.
In order to achieve the above objectives, the application uses following technological means:
A kind of sediment trapping bank structure for power plant building, comprising: sediment trapping bank main body, the sediment trapping bank main body are set to the hair
The one side in face sediment siltation area in front of power plant room, sediment siltation area described in the sediment trapping bank main body face is gradient face；It is several
Training for sediment pipe is arranged along the gradient face, and the import of the training for sediment pipe is located at the lower section in the gradient face, the training for sediment pipe
Outlet is located at the top in the gradient face；Aqueduct, is segmented along the training for sediment pipe and lays, and the aqueduct is led with described
The cloth set direction of sand tube intersects, and the entrance of the aqueduct is equipped with the packed rubble of anti-filter.
It is preferred that the import of the training for sediment pipe tilts upward.
It is preferred that the caliber of the training for sediment pipe and aqueduct is no more than 150 millimeters.
It is preferred that being spaced 10 meters -20 meters between each aqueduct.
The sediment trapping bank structure for power plant building due to using above-mentioned technological means, the application is optimised, and can be incited somebody to action
Silt before sediment trapping bank is drained as early as possible, has both been reduced silt and has been entered the risk that unit equipment is destroyed in power plant building, while can be according to reality
Border operating condition reduces the height of the sediment trapping bank structure for power plant building, to save engineering cost.
Detailed description of the invention
Fig. 1 is sediment trapping bank plan view described in the utility model.
Fig. 2 is sediment trapping bank training for sediment section cross-section diagram described in the utility model.
Fig. 3 is sediment trapping bank diversion section cross-section diagram described in the utility model.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Referring to shown in Fig. 1 to Fig. 3, Fig. 1 is sediment trapping bank plan view described in the utility model.Fig. 2 is this reality
With the novel sediment trapping bank training for sediment section cross-section diagram.Fig. 3 is sediment trapping bank diversion section cross-section diagram described in the utility model.
The sediment trapping bank structure, including sediment trapping bank main body 1, training for sediment pipe 2 and aqueduct 3 etc. for power plant building of the application
Structure.
The sediment trapping bank main body 1 is set to face sediment siltation area in front of the power plant building, and the sediment trapping bank main body is just
One side to the sediment siltation area is gradient face.Sediment trapping bank main body 1 can be in the embedded pvc pipe in inside as training for sediment pipe when constructing
2 and aqueduct 3.Training for sediment pipe 2 and aqueduct 3 must not arrange the stable structure and intensity for influencing sediment trapping bank 1, the size of caliber
It should be determined in conjunction with the structure size of sediment trapping bank 1 and possible siltation information summary, no more than 150mm.
Several training for sediment pipes 2 are arranged along the gradient face, and the import 21 of the training for sediment pipe 2 is located under the gradient face
Side, the import 21 of the training for sediment pipe tilt upward, depending on angle should combine the specific structural shape of sediment trapping bank 1, in order to silt
Can smoothly enter into.The outlet 22 of the training for sediment pipe 2 is located at the top in the gradient face.As depicted in figs. 1 and 2.Training for sediment pipe 2 is used for
The silt in area of depositing is drained.
Aqueduct 3 is segmented laying along the training for sediment pipe 2, and the cloth set direction of the aqueduct 3 and the training for sediment pipe 2 is handed over
Fork, section as shown in Figure 3, aqueduct 3 intersect with the training for sediment pipe 2, and water flow enters in training for sediment pipe 2 via aqueduct 3.Draw
Water pipe 3 is that training for sediment pipe 2 provides water body, so that 2 inside silt of training for sediment pipe more lubricates, silt excretion is more smooth.It is described
The packed rubble 4 of anti-filter is equipped at the import 31 of aqueduct 3.The packed rubble 7 of anti-filter ensures that aqueduct will not be blocked, while can consolidate
Determine residence and states aqueduct.10 meters -20 meters are spaced between each aqueduct 3.
The sediment trapping bank of the application not just stops silt, can even more drain silt, has both reduced silt entrance
The risk of unit equipment is destroyed in power plant building, while can reduce according to the actual operation the height of sediment trapping bank structure, to save
About engineering cost.
Embodiments described above is merely to illustrate the utility model rather than limitation the scope of the utility model.This
The equivalent changes and modifications that field technical staff does the utility model all should belong to the utility model the attached claims
The covering scope of book.
