The utility model is related to a kind of culvert pipe formula overflow bridge, it includes bridge dam base, the bridge dam base is using concrete structure pouring on riverbed, bridge pier has been poured on the bridge dam base, many culvert pipe side by side are poured inside the bridge pier, bridge floor is formed on the top of the bridge pier, and trash rack structure is provided with the upstream of bridge dam base.The bridge is applied to：Plain and some flood plain type rivers of slow mound area, river discharge are seasonal substantially, and embankment is very low or without obvious embankment, small traffic volume.
Description
Technical field
The utility model belongs to hydraulic engineering and traffic engineering design field, is a kind of culvert pipe formula overflow bridge.
Background technology
With developing rapidly for rural economy and social cause, motor vehicles, large-scale agricultural machinery quickly increase, in addition closely
The strong propulsion of sensible engineering in several years, road situation constantly improves, and the vast original bridge in rural area can not meet people group
All living creatures produce, the need for life and traffic, while external image is also poor, it is difficult to the throwing people that attracts foreign investment, constrain in various degree through
The development of Ji.At present, rural area bridge is broadly divided into the types such as beam bridge, arch bridge, slab bridge, cable-stayed bridge and suspension bridge, these species according to
Different physical features or demand application and give birth to, have respective advantage and disadvantage, but the requirement of some middle and small rivers can not be met.For flat
Former and some flood plain type rivers of slow mound area, they are located in rural area, and river discharge is seasonal substantially, and embankment is very low or without obvious
Embankment, small traffic volume, if or it is high with common above-mentioned bridge type construction cost, or technical difficulty is big.
Utility model content
The purpose of this utility model is to provide a kind of simple, practical, overflow bridge of low cost.The bridge is applied to：Plain and
Some flood plain type rivers of slow mound area, river discharge is seasonal substantially, and embankment is very low or without obvious embankment, and the volume of traffic is not
Greatly.
In order to solve the above-mentioned technical problem, the utility model proposes following technical scheme：A kind of culvert pipe formula overflow bridge, it is wrapped
Bridge dam base is included, the bridge dam base on riverbed, bridge pier, institute has been poured on the bridge dam base using concrete structure pouring
State and many culvert pipe side by side are poured inside bridge pier, bridge floor is formed on the top of the bridge pier, is provided with the upstream of bridge dam base
Trash rack structure.
The trash rack structure includes side column, and many crossbeams are welded between the side column, and the crossbeam uses I-steel
It is made, many grizzly bars is welded with by grizzly bar connecting plate on the crossbeam, the whole trash rack structure is inserted into blocks dirt
On grid chute, the trash rack chute is cast in the both sides of bridge dam base.
The culvert pipe is formed using concreting, and many reinforcing bars have been poured inside it.
The hardware outer surface of the trash rack structure is all coated with antirust paint and carries out anti-corrosion treatment.
The utility model has the advantages that：
The culvert pipe formula overflow bridge being made according to such scheme, debris blocked water culvert pipe in can preventing water.In the akhet
Section, unnecessary flow can be by bridge floor above by general season river passes through from culvert pipe.Program construction cost is low, typically
10 meters of wide river courses build the overflow bridge, cost at more than 10,000 yuan, in vast Plain and slow hilly area, can yet be regarded as it is a kind of it is economical, applicable,
Lifetime type of bridge long.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is culvert pipe of the present utility model and cloth muscle schematic diagram.
Fig. 3 is trash rack side view of the present utility model.
Fig. 4 is trash rack left view of the present utility model.
Fig. 5 is trash rack chute of the present utility model and trash rack structure mounting structure schematic diagram.
In figure：Bridge floor 1, bridge pier 2, culvert pipe 3, bridge dam base 4, trash rack structure 5, trash rack chute 6, side column 501, crossbeam
502nd, grizzly bar connecting plate 503, grizzly bar 504.
Specific embodiment
Implementation method of the present utility model is described further below in conjunction with the accompanying drawings.
Such as Fig. 1-5, a kind of culvert pipe formula overflow bridge, it includes bridge dam base 4, and the bridge dam base 4 uses concrete structure
It is cast on riverbed, bridge pier 2 has been poured on the bridge dam base 4, many culvert pipe 3 side by side, institute is poured inside the bridge pier 2
Bridge floor 1 is formed on the top for stating bridge pier 2, and trash rack structure 5 is provided with the upstream of bridge dam base 4.
Wherein, bridge floor is convex-shaped, the material thickness of bridge floor to culvert pipe to take into full account road surface communications and transportation situation and
The stressing conditions of culvert pipe；Culvert pipe is reinforcement prestressing force prefabricated component, and culvert pipe internal diameter and culvert pipe mouthful number mainly by water flow and cross water
There is certain connection that width is installed depending on section width, between culvert pipe and culvert pipe；Bridge dam base is supported for whole pontic stress,
Stressing conditions are taken into full account, bridge dam base bottom is excavated and need to carried out by specification.
Further, the trash rack structure 5 includes side column 501, and many crossbeams 502 are welded between the side column 501,
The crossbeam 502 is made of I-steel, and many grizzly bars are welded with by grizzly bar connecting plate 503 on the crossbeam 502
504, the whole trash rack structure 5 is inserted on trash rack chute 6, and the trash rack chute 6 is cast in the two of bridge dam base 4
Side.
The culvert pipe formula overflow bridge being made according to such scheme, debris blocked water culvert pipe in can preventing water.In the akhet
Section, unnecessary flow can be by bridge floor above by general season river passes through from culvert pipe.Program construction cost is low, typically
10 meters of wide river courses build the overflow bridge, cost at more than 10,000 yuan, in vast Plain and slow hilly area, can yet be regarded as it is a kind of it is economical, applicable,
Lifetime type of bridge long.
Further, the culvert pipe 3 is formed using concreting, and many reinforcing bars 301 have been poured inside it.Above-mentioned culvert
Pipe 3 can not only bear certain bridge floor pressure, and can play the purpose of draining, accordingly, it would be desirable to be made using built-in reinforcing bar
For skeleton is fastened.
Further, the hardware outer surface of the trash rack structure 5 is all coated with antirust paint and carries out at anti-corrosion
Reason.Its service life can be extended by antirust treatment.
The course of work of the present utility model and operation principle are：
The culvert pipe formula overflow bridge being made according to such scheme, debris blocked water culvert pipe in can preventing water.In the akhet
Section, unnecessary flow can be by bridge floor above by general season river passes through from culvert pipe.Program construction cost is low, typically
10 meters of wide river courses build the overflow bridge, cost at more than 10,000 yuan, in vast Plain and slow hilly area, can yet be regarded as it is a kind of it is economical, applicable,
Lifetime type of bridge long.
By above-mentioned description, those skilled in the art completely can be without departing from this utility model technological thought
In the range of, carry out various changes and amendments all within protection domain of the present utility model.It is of the present utility model not most
Matters, belong to the common knowledge of those skilled in the art.
