Abstract
The invention discloses a kind of RCC dam structures in hydraulic and hydroelectric engineering, it includes the RCC dam body (2) formed by several grinding coagulation soil layers (5), multistage barricade (4) is arranged in the downstream face (3) of the dam body, the dam formula barricade that every level-one barricade all uses concrete formed by integrally casting to be formed, and next stage barricade and upper level barricade build-in form continuous step-like anti-skid body.Wherein, level-one barricade is arranged in every layer 2-3 grinding coagulation soil layer, and the height of every grade of barricade is equal to its opposite the sum of grinding coagulation soil layer thickness.The anti-skid body that the present invention is formed by dam formula barricade can increase the anti-slide performance of roller compacted concrete interlayer, and dam body Parallel to the flow direction is inhibited to deform, and the present invention is not necessarily to additional equipment and Skid Resistance Measures, save the cost.
Description
Technical field
The present invention relates to hydraulic and hydroelectric engineering dam body, especially a kind of RCC dam structure.
Background technique
RCC dam is because using concrete membrane layering stone, rolling, the continuous dam construction technique for rising construction,
It being widely applied both at home and abroad, but engineering practice proves, Coating combination is second-rate between grinding coagulation soil thin layer and thin layer, in conjunction with
Intensity is lower, and dam is easy Parallel to the flow direction and is deformed.
Summary of the invention
The technical problem to be solved by the present invention is in view of the shortcomings of the prior art, providing one kind can increase interlayer antiskid energy
Power, and inhibit the RCC dam structure of Parallel to the flow direction deformation.
In order to solve the above technical problems, the technical scheme adopted by the invention is that: a kind of RCC dam structure, including
Multistage barricade, every level-one gear is arranged in the RCC dam body formed by several grinding coagulation soil layers, the downstream face of the dam body
The dam formula barricade that wall all uses concrete formed by integrally casting to be formed, and next stage barricade and upper level barricade build-in form continuous platform
The anti-skid body of scalariform.
One preferred embodiment of above scheme is that level-one barricade, and every grade of barricade is arranged in every layer 2-3 grinding coagulation soil layer
Height be equal to its opposite the sum of grinding coagulation soil layer thickness, guarantee barricade intensity and stability on the basis of, ensure that
The anti-slide performance of roller compacted concrete interlayer.
One specific embodiment of above scheme is the interior upper angle of next stage barricade and the outer inferior horn build-in of upper level barricade
It pours, barricades at different levels is made to form one, to further increase the anti-slide performance of roller compacted concrete interlayer, inhibit dam body downstream
Stream direction deforms.
One preferred embodiment of above scheme is that the longitudinal section of the dam formula barricade is trapezium structure, so that gear
The stability and impact resistance of wall are more preferable.
It should be noted that the longitudinal section in the present invention refers to the section parallel with water (flow) direction.
The present invention is by being arranged multistage dam formula barricade, and next stage barricade and upper level in RCC dam body downstream face
Barricade build-in forms continuous step-like anti-skid body, in this way, impact resistance is stronger due to the stability of dam formula barricade, thus energy
Increase the anti-slide performance of roller compacted concrete interlayer, dam body Parallel to the flow direction is inhibited to deform, and the present invention is set without additional
Standby and Skid Resistance Measures, save the cost.
Barricade of the present invention forms continuous anti-skid body, and anti-skid body is integrally in step that is step-like, can be used for when small flow behind dam
Energy dissipating.
Detailed description of the invention
The following further describes the present invention with reference to the drawings.
Fig. 1 is RCC dam typical case profilograph of the present invention.
Fig. 2 is RCC dam of the present invention and barricade junction fragmentary longitudinal section enlarged drawing.
In figure: 1-original place upper thread；2-dam bodys；3-downstream faces；4-barricades；5-grinding coagulation soil layers.
Specific embodiment
As shown in Figure 1 and Figure 2, one embodiment of RCC dam of the present invention includes a dam body 2, the downstream face 3 of the dam body 2
Multistage barricade 4, and next stage barricade and upper level barricade build-in are set, to form continuous anti-skid body.The anti-skid body is in downstream
Face 3 is integrally formed that level-one grade is step-like, can be used for Step Energy Dissipation when small flow behind dam.
The height of barricade 4 is depending on the thickness of grinding coagulation soil layer 5, for convenient for construction and step setting, general every 2-3
Level-one barricade 4 is arranged in layer grinding coagulation soil layer.
Barricade 4 preferably uses cross section for the dam formula barricade of trapezium structure, to be spread out in grinding coagulation soil layer 5 convenient for construction
Barricade 4 can be first poured before paving；Or the thickness clear band of grinding coagulation soil layer 5 can be reserved, barricade 4 is first poured, then pave coagulation
Soil connects with barricade 4.
For increase downstream face 3 barricade 4 stability, by angle A upper in next stage barricade and upper level barricade it is outer under
Angle B build-in pours, to form continuous anti-skid body.
Claims (4)
1. a kind of RCC dam structure, including the RCC dam body (2) formed by several grinding coagulation soil layers (5),
It is characterized in that, multistage barricade (4) is arranged in the downstream face (3) of the dam body, every level-one barricade all uses concrete formed by integrally casting
The dam formula barricade of formation, and next stage barricade and upper level barricade build-in form continuous step-like anti-skid body.
2. a kind of RCC dam structure according to claim 1, which is characterized in that every layer 2-3 grinding coagulation soil layer
Level-one barricade is set, and the height of every grade of barricade is equal to its opposite the sum of grinding coagulation soil layer thickness.
3. a kind of RCC dam structure according to claim 1, which is characterized in that the interior upper angle of next stage barricade
(A) it is poured with outer inferior horn (B) build-in of upper level barricade.
4. a kind of RCC dam structure according to claim 1, which is characterized in that the longitudinal section of the dam formula barricade
For trapezium structure.
