Description
Technical field
The present invention relates to hydraulic and hydroelectric engineering field more particularly to a kind of mountain stream river levee engineerings.
Background technique
Mountain stream river refers to that flow through the relatively narrow depth of Mountain Area landforms, valley cross section, vertical section does not advise than dropping larger, bank line
River then, since the mountain stream stream gradient big concentration time is very brief, flood season easily forms rain flood, and The turbulent river crashes its way through, rises suddenly and falls suddenly,
Water velocity is very fast, therefore its water front and riverbed are washed away and corroded vulnerable to more serious.
Mountain stream River Flood dike engineering, which protects dike, must first consolidate bank slope protection.The damage of dyke building, except because arranging inappropriate, dike
Body structural strength is inadequate or construction quality is poor outer, excessively shallow often caused by the depth of burying, so that basis is emptied and caused by water flow
's.
In order to avoid dyke building basis is emptied by water flow, mountain stream river wall structure buried depth is deeper.As shown in Figure 1, existing
There is the dike structure of mountain stream river levee engineering to be an integral structure, although can satisfy coarse granule bed load and silt to dyke
The shock of structure is pounded and is touched, but foundation excavation, backfill and dike structure concrete works amount are larger.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of mountain stream river levee engineering that can save cost.
In order to solve the above problem the technical solution adopted is that: mountain stream river levee engineering include riverbed and be located at riverbed two sides
Riverbank, the junction on riverbed and riverbank is provided with dike structure, Anti-scouring structure foundation pit and dyke main body foundation pit, dyke main body
Foundation pit is more shallow than Anti-scouring structure foundation pit；Dike structure includes Anti-scouring structure and dyke main body；Anti-scouring structure is from protection against erosion knot
Structure bottom of foundation ditch extends upwardly to dyke main body along Anti-scouring structure foundation pit lateral surface, in the remaining space of Anti-scouring structure foundation pit
Stone filling；Dyke bottom part body is arranged in dyke main body foundation pit, in the dyke main body foundation pit on the outside of dyke main body and riverbank
Upper constructing soil stone；Water sealing structure is set between Anti-scouring structure and dyke main body.
Further, Anti-scouring structure bottom buried depth H >=3m.
Further, Anti-scouring structure and dyke main body are made of concrete or armored concrete.
The beneficial effects of the present invention are: comparison diagram 1 and Fig. 2.Prior art Anti-scouring structure and dyke main body are integral types
Structure, dyke bottom part body is identical as Anti-scouring structure bottom depth, so that dike structure foundation pit is very big, foundation excavation, backfill
And dike structure concrete works amount is larger.The application Anti-scouring structure and dyke main body are provided separately, dyke main body foundation pit
Shallower, the total volume of dyke main body foundation pit and Anti-scouring structure foundation pit is significantly less than the dike structure foundation pit of the prior art, so that
Foundation excavation, backfill and dike structure concrete works amount are smaller.The application excavated volume can reduce about 30%, and backfill amount can subtract
Few about 20%, amount of concrete can reduce about 20%, therefore can be substantially reduced the construction investment of mountain stream river levee engineering；Simultaneously
Also it can satisfy protection against erosion requirement.
Detailed description of the invention:
Fig. 1 is the mountain stream river levee engineering structure schematic diagram of the prior art；
Fig. 2 is the mountain stream river levee engineering structure schematic diagram of the application；
In the figure, it is marked as riverbed 1, riverbank 2, dike structure foundation pit 3, native stone 4, block stone 5, dike structure 6, dyke main body
61, Anti-scouring structure 62, dyke main body foundation pit 7, Anti-scouring structure foundation pit 8, water sealing structure 9.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in Figure 2: mountain stream river levee engineering includes riverbed 1 and positioned at the riverbank 2 of 1 two sides of riverbed, riverbed 1 and riverbank
2 junction is provided with dike structure 6, Anti-scouring structure foundation pit 8 and dyke main body foundation pit 7, and dyke main body foundation pit 7 compares protection against erosion
Structure foundation pit 8 is shallow；Dike structure 6 includes Anti-scouring structure 62 and dyke main body 61；Anti-scouring structure 62 is from Anti-scouring structure base
It cheats 8 bottoms to extend upwardly at dyke main body 61 along 8 lateral surface of Anti-scouring structure foundation pit, the residue of Anti-scouring structure foundation pit 8 is empty
Interior stone filling 5；61 bottom of dyke main body is arranged in dyke main body foundation pit 7, the dyke main body base in 61 outside of dyke main body
Hole 7 in and riverbank 2 on constructing soil stone 4；Water sealing structure 9 is set between Anti-scouring structure 62 and dyke main body 61.
The application block stone 5 plays the role of first of protection against erosion, washes away seriously, when block stone 5 fails, Anti-scouring structure 62 is played
The effect of second protection against erosion can be avoided current scour to the basis of dyke main body 61, guarantee 61 safety of dyke main body.Native stone 4
Play the role of supporting fixed dyke main body 61 together with basis.
Water sealing structure 9 avoids water flow from entering in the parting between Anti-scouring structure 62 and dyke main body 61.Water sealing structure 9 is
The prior art, specifically embedded copper sheet, stainless steel substrates, rubber, intumescent rubber, plastics, pitch and Polymer Synthesizing material
Material etc. carries out sealing.
The application Anti-scouring structure 62 and dyke main body 61 are provided separately, when foundation uneven settlement, Anti-scouring structure
62 and dyke main body 61 be suitable for differential settlement, avoid drawing crack.It is likely to occur drawing crack situation if the setting of the two integral type, after
Fruit is serious.Water sealing structure 9 is flexible structure, even if Anti-scouring structure 62 and 61 relative motion of dyke main body will not generally also lose
Effect.
Mountain stream river channel erosion depth is deeper, and 62 bottom buried depth H of Anti-scouring structure should be greater than mountain stream river channel erosion depth, usually
62 bottom buried depth H >=3m of Anti-scouring structure.
Anti-scouring structure 62 and dyke main body 61 are same as the prior art, are made of concrete or armored concrete.
Dotted line a is the ground line built before mountain stream river levee engineering in the application Fig. 1 and Fig. 2.
