Description
Technical field
The utility model is related to subgrade engineering, specifically a kind of novel discharge culvert.
Background technology
The effect of culvert is the rapid surface water for excluding Highways ', ensures roadbed safety.Under prior art conditions, contain
Hole is broadly divided into slab culvert, arch culvert, box culvert etc..However practice have shown that, existing culvert is both needed to when being set to excavation section using bright
Digging method is constructed, and thus causing it to take up an area, range is big, difficulty of construction is high, project cost is high, big to eco-environmental impact.It is based on
This, it is necessary to a kind of completely new culvert is invented, takes up an area that range is big, difficulty of construction to solve existing culvert when being set to excavation section
High, project cost height, the problem big to eco-environmental impact.
Invention content
The utility model takes up an area that range is big, difficulty of construction is high, engineering in order to solve existing culvert when being set to excavation section
Cost height, the problem big to eco-environmental impact, provide a kind of novel discharge culvert.
The utility model adopts the following technical scheme that realization：
A kind of novel discharge culvert, including wall body, inverted arch lining cutting, inverted arch filling；Wall body includes preliminary bracing, secondary lining
It builds；Wherein, preliminary bracing is anchor spraying concrete layer；Secondary lining be form concrete layer, and the lateral surface of secondary lining with just
The medial surface of phase supporting is fixed as one；Inverted arch lining cutting is form concrete layer, and the thickness of inverted arch lining cutting and secondary lining
Consistency of thickness；The two sides of inverted arch lining cutting are fixed as one with the two sides of secondary lining respectively, and inverted arch lining cutting and secondary lining
Block surrounds loop configuration jointly；Inverted arch is filled with cast-in-place concrete layer, and the inside of the lateral surface and inverted arch lining cutting of inverted arch filling
Face is fixed as one.
When work, the medial surface of inverted arch filling and the medial surface of secondary lining surround drainage channel jointly.With existing culvert
It compares, a kind of novel discharge culvert described in the utility model is constructed when being set to excavation section without cut and cover method,
And need to only be constructed using subsurface excavation method, therefore it takes up an area that range smaller, difficulty of construction is lower, project cost is lower, to ecology
Environment influences smaller.In addition, a kind of novel discharge culvert described in the utility model is by using loop configuration（The loop configuration
It is surrounded jointly by inverted arch lining cutting and secondary lining）, effectively increase structural stability, therefore it is by settlement influence smaller, antidetonation
Ability is stronger.
The utility model is reasonable for structure, ingenious in design, efficiently solves existing culvert and takes up an area model when being set to excavation section
Big, difficulty of construction height, project cost height, the problem big to eco-environmental impact are enclosed, excavation section subgrade drainage is suitable for.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1a- preliminary bracings, 1b- secondary linings, 2- inverted arch lining cutting, the filling of 3- inverted arch.
Specific implementation mode
A kind of novel discharge culvert, including wall body, inverted arch lining cutting 2, inverted arch filling 3；Wall body includes preliminary bracing 1a, secondary
Lining cutting 1b；Wherein, preliminary bracing 1a is anchor spraying concrete layer；Secondary lining 1b is form concrete layer, and secondary lining 1b
The medial surface of lateral surface and preliminary bracing 1a is fixed as one；Inverted arch lining cutting 2 is form concrete layer, and the thickness of inverted arch lining cutting 2
The consistency of thickness of degree and secondary lining 1b；Two sides of the two sides of inverted arch lining cutting 2 respectively with secondary lining 1b are fixed as one,
And inverted arch lining cutting 2 and secondary lining 1b surround loop configuration jointly；Inverted arch filling 3 is cast-in-place concrete layer, and inverted arch fills 3
Lateral surface and the medial surface of inverted arch lining cutting 2 are fixed as one.
The distance between the lateral surface top of preliminary bracing 1a and the lateral surface top of inverted arch lining cutting 2 are 653cm；Initial stage branch
The distance between lateral surface left end and the lateral surface right end for protecting 1a are 702cm.When work, above-mentioned size design makes culvert open
Spoir amount is less during digging, is thus conducive to environmental protection.
Wall is as bent wall wall body, and the internal diameter of vault is 300cm, and the internal diameter of side curl wall is 600cm；Inverted arch serves as a contrast
The internal diameter for building 2 is 679cm.When work, bent wall wall body can enhance the bearing load ability of culvert, thus further increase knot
Structure stability.
The thickness of preliminary bracing 1a is 16cm；The thickness of secondary lining 1b, the thickness of inverted arch lining cutting 2 are 35cm；Inverted arch
The maximum gauge of filling 3 is 48cm.
The concrete of preliminary bracing 1a, the concrete of secondary lining 1b, inverted arch lining cutting 2 concrete be C25 concrete；
The concrete of inverted arch filling 3 is C20 piece stone concretes.
