Description
Technical field
The present invention relates to hydraulic engineering river regulation fields, and in particular to one kind adapts to construction time severe hydrometeorological item
The channel revetment project post-evaluation structure of part.
Background technique
Bank slope protection is the important component of river controlling projects, directly the stable, Seawall safety or even anti-concerning river regime
Big vast safety.Entire safeguard structure is divided into slope protection and water waterborne using stone masonry or cast-in-place concrete foot slot by traditional defense scheme
Lower spats two parts.Protective slope structure waterborne is more more stable than underwater spats structure, and underwater spats structure expose the surface after appearance compared with
Ugliness, thus the lower foot slot elevation the better, however influenced by construction time water level, foot slot elevation is too low to be will be unable to construct, generally
Foot groove top elevation is 0.5~1.0m higher than design low water position.
Bank-protection works requires to complete within a dry season, and dry season long-time water level is higher, rainfall all will seriously affect
Site operation, if bank slope geological conditions is bad, soil body long-time rainwater, which impregnates after-tack, can not excavate molding, and the duration is even more nothing
Method guarantees.If cannot complete on time, problem of temporarily passing the flood period will be faced, bank-protection works battle line is long, it temporarily passes the flood period at high cost, risk
Greatly.
Summary of the invention
The object of the present invention is to provide a kind of channel revetment engineering shields for adapting to construction time severe hydrometeorological condition
Slope structure, proposed by the present invention to raise foot slot elevation slope protection is divided into top slope protection and lower part slope protection, lower part slope protection is pre-manufactured steel
Cobblestone is filled out on lower layer's pouring concrete, upper layer in reinforced concrete frame, is improved slope protection works construction time anti-interference ability, is combined
Runtime stabilization, beautiful channel revetment project post-evaluation structure；Its solve construction time water level it is higher cannot construct lead to not by
When completion and engineering build up rear underwater portion expose when the not beautiful problem of appearance.
To achieve the above object, a kind of channel revetment adapting to construction time severe hydrometeorological condition designed by the present invention
Project post-evaluation structure, it is formed by connecting side by side by multiple slope protection units, and the slope protection unit is by underwater spats structure and shield waterborne

It states lower layer's cast-in-place concrete intermediate vertical and is provided with drainage hole.
Further, the intermediate concrete foot slot elevation raises 0~2m；Intermediate concrete foot slot support top shield
It is tilted on slope aspect, in horizontal connection, the centre is raised for the upper surface of the intermediate concrete foot slot upper surface and lower part slope protection
Foot bottom surface is lower than the bottom surface of top slope protection and lower part slope protection, and it is broken that the intermediate concrete foot slot lower part is successively equipped with sand
Stone bed course and concrete cushion, the intermediate concrete foot slot both ends are symmetrically arranged with clamp and card slot, and the card slot is vertical
Through the entire side of intermediate concrete foot slot, the card slot is engaged with the clamp of another slope protection unit and cement injection mortar
Connection.
Still further, the intermediate concrete foot slot is spaced apart equipped with multiple solid with the end face top that lower part slope protection connects
Determine slot, the reinforced concrete frame top of the lower part slope protection is provided with the fixed chuck with fixing groove cooperation, the fixing groove
With fixed chuck occlusion and cement injection mortar is connect.
Still further, the frame mesh shape of the reinforced concrete frame be parallelogram, side length be 0.5~
1.5m；Beam cross section width is 10~30cm, thickness be 20~40cm (mesh shape of precast reinforced concrete frame, size and
Beam cross sectional dimensions can be adjusted according to requirement of engineering), the lower layer of the reinforced concrete frame is sand blotter.
Still further, the cast-in-place concrete with a thickness of 12~15cm.
Still further, the partial size of the cobblestone be 5~15cm (cobblestone is loose structure, can also part it is cementing, face
Color is preferred with colour).
Beneficial effects of the present invention:
1, the present invention raises foot slot elevation, reduces influence of the construction time flood level to engineering construction.
2, fabricated construction of the present invention, construction is fast, can shorten the construction period.
3, lower part protective slope structure of the present invention is connect using reinforced concrete structure with foot slot, fill concrete in frame mesh
And there are drainage hole, the local strengthening stability of the following safeguard structure of foot slot.
4, reinforced concrete frame structure of the present invention can go deep into low water level hereinafter, cobblestone is filled on frame mesh upper layer, solution
Aesthetic problem when low level water flowering structure of having determined exposes the surface.
In conclusion bank-protection works sequence of construction is first construct underwater spats, then foot slot of constructing, shield waterborne of finally constructing
Slope.Underwater spats is operation at sea, and slope protection elevation waterborne is higher, is influenced by dry season water level smaller, thus bank-protection works is constructed
Controlling node be foot slot construction.It raises foot slot elevation and slope protection waterborne is divided into top protective slope structure and lower part protective slope structure,
Influence of the flood to construction can be reduced, fabricated construction can save the duration, and lower part slope protection is using in precast reinforced concrete frame
The stabilization and beauty of the certifiable engineering of structure of lower layer's pouring concrete, upper layer paving cobblestone.With structure safety, good appearance,
The characteristics of convenient, strong antijamming capability of constructing.
