Description
Technical field
The utility model belongs to hydraulic and hydroelectric engineering building technology field, and in particular to a kind of hammed water dam water intaking structure.
Background technique
In the construction of hydropower stations or other engineerings, to solve construction period production and living problem of water consumption, it will usually in Project Areas
Natural ditch bed is nearby found, open water supply is introduced into production and living area for using.However, the natural ditch bed one near Project Areas
As all along with the generation of mud-rock flow, once by hammed water dam, conduit pipe block, entire water intake system will be made to lose water intaking
Function.
Utility model content
The purpose of the utility model is to overcome problems of the prior art, after a kind of dam using hammed water dam is provided
Water intaking structure is to be suitable for from similar engineerings such as the groove water intakings for having mud-rock flow to occur.
To achieve the goals above, the technical solution adopted in the utility model is as follows:
A kind of hammed water dam water intaking structure, including overflow weir, grid, water intaking slot, water storage tank and dam rear defence watch box；Wherein,
Water intaking slot is vertically opened on the slope of the overflow weir behind dam, and grid paving, which is obliquely set to, takes sink top；Water storage tank is side by side
Ground is set to the side of water intaking slot and realizes water flow in water intaking slot and water storage tank by the water inlet that groove sidewall bottom opens up of fetching water
Between flowing；Plane where the bottom plate of water storage tank is equipped with lower than the bottom of plane and water storage tank where the bottom plate of water intaking slot draws
Waterpipe；Dam rear defence watch box picks out from overflow weir bottom and is arranged along slope.
Further, fetch water slot rear top of the slope portion be equipped with one for grill support platform.
Further, the bar spacing of grid is 20mm.
Further, the drop height of water storage trough floor and water intaking trough floor is at least 0.5m.
Further, water storage tank is open type vertical shaft type structure.
Further, the suitable slope gradient of dam rear defence watch box is 1:(1~2).
Further, overflow weir weir crest is using arc-shaped.
Further, fetch water slot two sides be upright slope.
Further, the width of platform is 0.3~0.5m.
Further, the inclined direction of grid and tilt angle are consistent with the slope of overflow weir.
The technical solution of the utility model, by the way that water intaking slot and water storage tank are arranged behind dam, and by grid to finger stone
And the blocking of other alluvial deposits after mud-rock flow occurs entire diversion system so that can operate normally；Meanwhile behind dam
The design of protection body washes in a pan hammed water dam destabilization problems caused by foot, the not only structure letter of entire technical solution after capable of effectivelying prevent dam
It is single, convenient to carry out, and excellent effect, there is good practicability.
Detailed description of the invention
Fig. 1 is the floor plan of the utility model.
Fig. 2 is the A-A cross-sectional view of the utility model.
Fig. 3 is the B-B cross-sectional view of the utility model.
Fig. 4 is the C-C cross-sectional view of the utility model.
Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
Referring to attached drawing.The utility model is equipped with including overflow weir 2, grid 3, water intaking slot 4, water storage tank 7 and dam rear protecting
Body 5.For small-sized hammed water dam, for 2 weir crest of overflow weir using arc-shaped, the specific radius of circular arc is true according to hammed water dam scale
It is fixed.Water intaking slot 4 is vertically opened on the slope of the overflow weir 2 behind dam, and the paving of grid 3 is obliquely set to 4 top of water intaking slot, grid
3 inclined direction and tilt angle is consistent with the slope of overflow weir 2.Wherein, the two sides of water intaking slot 4 are upright slope, rear top of the slope
Portion be equipped with one for grill support platform 9, the width of platform 9 is 0.3~0.5m.Specifically, fetching water the size dimension of slot 4 can be with
It is calculated and is determined according to water intaking scale.3 outline border of grid is made of L50*5 angle steel, and interior grid uses 20 reinforcement fabrication of φ, between reinforcing bar
Away from for 20mm, so as to prevent gravelstone and other alluvial deposits from entering water intaking slot 4, the blocking of conduit pipe 8 is avoided.Due to this reality
With novel for structure of fetching water behind a kind of dam, thus the structure allow to be become silted up by mud-rock flow or other solid material resources before hammed water dam it is full, but
It cannot become silted up behind dam full.For this purpose, the addressing of hammed water dam is preferably that 1 condition of landform is gentle before dam, in favor of building dam, landform 1 is mutated behind dam,
Head fall in 20%, arranges in downstream in order to cover mud-rock flow or other solid material resources on hammed water dam suddenly, avoids to become silted up behind dam
It is full.
6 reality of water inlet that water storage tank 7 is abreast set to the side of water intaking slot 4 and is opened up by 4 sidewall bottom of slot of fetching water
The size of flowing of the existing water flow between water intaking slot 4 and water storage tank 7, water inlet 6 can be determined according to water intaking scale is comprehensive.Water storage
Plane where the bottom plate of slot 7 is at least 0.5m, similarly, h lower than plane, the drop height h of the two where the bottom plate of water intaking slot 4
Specific value determined according to local water intaking scale is comprehensive.Conduit pipe 8 is installed on the bottom of water storage tank 7, thus by water storage
Water body in slot 7 leads to construction area or living area according to programme path.In the present embodiment, water storage tank 7 is open type vertical shaft type
Structure.
The technical program is additionally provided with for washing in a pan foot after preventing dam, causes the dam rear defence watch box 5 of hammed water dam destabilization problems.The dam
Rear defence watch box 5 is poured by low-grade concrete, is picked out from 2 bottom of overflow weir and is arranged along slope, is 1:(1 along the slope gradient
~2).
It should be pointed out that the embodiments of the present invention are described above.However, the technical staff of art technology should manage
Solution, the present utility model is not limited to the above embodiments, only illustrates the principles of the present invention described in above-described embodiment,
There are many changes and improvements for the utility model also meeting under the premise of not departing from the scope of the utility model, these changes and improvements are all
It falls within the scope of the claimed invention.
