Description
Technical field
The present invention relates to a kind of flood retarding project structure being applied to low head condition, be specifically related to a kind of narrow deep formula sharp-crested weir
Steel bar concrete barrage structure.
Background technology
At present, designing unit, when carrying out the design of small-sized dam project, uses WES type practical weir structures, this structure more
The thick and heavy self gravitation that stably relies primarily on maintains sliding stability, and weir surface curve met the streamline feature of dam current, and increased stream
Coefficient of discharge makes it have the advantage that discharge capacity is big, but substantial amounts of reinforced concrete material is used by it only as ballast, it is impossible to send out
Waving its transverse property the most uneconomical, cost is higher；It is big that the curved design used increases difficulty of construction, and construction quality is difficult to control
System, thus results in discharge coefficient and is extremely difficult to design load；Straight floor design causes its permeation pathway short, it is generally required to lengthen
The mode of bedding and protection-apron maintains seepage stability, and compared to anti-seepage effect more preferable vertical seepage control structure, (anti-seepage effect is level
3～5 times of leakage preventing structure), it puts into height and but produces effects low.
Therefore, building the universal acting head of barrage structure on plain type river course the lowest, water retaining height many is all
Using traditional WES type practical weir structure to can be compared under the conditions of below 3.0m is this is " mosquito beaten by shell ", permissible in effect, but
The most uneconomical, cause the wasting of resources.
Summary of the invention
The present invention is to solve that head is many at below 3.0m on plain type river course, uses traditional WES type practical weir to tie
Structure, the problem causing the wasting of resources, the invention provides a kind of upright cross narrow deep thin-walled barrage.
A kind of upright cross narrow deep thin-walled barrage, it includes checkdam, horizonal base plate and cuts and ooze plate；
Checkdam, horizonal base plate and cut and ooze plate and made by armored concrete；Checkdam is used for intercepting river, raising water
Position, checkdam is vertically set in the earth of river bed,
Horizonal base plate is vertically fixed on bottom checkdam,
Cut and ooze plate and be positioned at the lower section of horizonal base plate, and vertical with horizonal base plate fix.
Checkdam and cut and ooze plate symmetry and be fixed on the upper and lower surface same position of horizonal base plate, three constitutes cross knot
Structure.
Checkdam and cut and ooze Board position and interlock and be fixed on the upper and lower surface of horizonal base plate.
Cut that to ooze the quantity of plate be two, and centered by the vertical direction of checkdam, mirror image is arranged on the both sides of checkdam.
The thickness of described horizonal base plate is more than checkdam and cuts the thickness oozing plate.
A kind of upright cross narrow deep thin-walled barrage, it also includes that multiple triangle counterfort supports, and triangle counterfort props up
Support is made up of armored concrete, and multiple triangle counterforts support and are evenly distributed on the downstream of checkdam, be fixed on checkdam and
Between horizonal base plate.
Described dash dam thickness is 50cm～60cm.
The thickness of described horizonal base plate is 80cm～100cm.
Described cut that to ooze the thickness of plate be 40cm～60cm.
The present invention is directed to the feature that low water head flood retarding project upstream and downstream head difference is little, load level is low, it is provided that Yi Zhongzhi
Vertical cross narrow deep thin-walled barrage structure.The present invention is a kind of reinforced concrete sheet pile structure vertically going deep into riverbed, crosses stream
Characteristic is identical with sharp-crested weir structure, and its section configuration being noteworthy characterized by Parallel to the flow direction is " cross ".During dash, in upstream
Under the effect of water pressure, structure will be so that on it, any, as center of rotation, occurs minor rotation, now downstream more than center of rotation
The upstream side soil body below the side soil body and center of rotation is in Passive deformation state, and generation passive earth pressure is reacted on " ten
Font " structure, structure relies on this passive earth pressure to remain stable；Structure size in vertical direction is very big, becomes horizontal seepage paths
For the lower vertical line structure of vertical seepage paths, particularly " cross ", be equivalent to one section and ooze plate, significantly improve the impervious energy of structure
Power, can reduce the length of bedding and protection-apron under equal conditions.
The beneficial effect that the present invention brings
Compared to thick and heavy WES type practical weir structure, the present invention has a significant advantage of five aspects:
One, unstability type is become bending from planar slide and topples by narrow deep foundation, and the passive earth pressure that force value is bigger can
Ensureing that the antidumping of structure is stable, Reinforced Concrete Materials most will give full play to its transverse property, it is to avoid functional waste；
Two, each face of structure is plane, simple in construction, it is simple to construction, and quality is also easy to control；
Three, upright cross narrow deep formula thin-walled barrage structure levels off face seepage paths is vertical seepage paths, significantly improves structure
Anti-seepage effect；
Four, upright cross narrow deep formula thin-walled barrage structure changes massive structure is thin-wall construction, reduces structure section
Area, saves substantial amounts of concrete material, significantly reduces construction costs；
Five, upright cross narrow deep formula thin-walled barrage structure does not has roomy base plate, it is easy to the tangent coordinate system of control
Instead of the Normal frost heave being difficult to control, improve the ability that Engineering Anti freeze injury destroys.
Present invention is mainly used for the flood retarding project that water retaining height is less than 3 meters.
