Technical field
The utility model relates to transport development field more particularly to a kind of assembled irrigation canals and ditches arch bridges.
Background technique
At present the bridge overwhelming majority on the river and channel in park, sight spot and rural area be all concrete cast-in-situ, steel structure with
And wooden structure, there are also a small number of to have blocks of natural stone to pile up.The bridge of various materials has the advantage of itself, but disadvantage
Clearly.The normal concrete cast-in-situ bridge duration is longer, and quality is difficult to control, and heavy, the later period scrap after cannot dismantle two
Secondary utilization, increases environmental pressure.The production of steel structure bridge is simple, but the Corrosion Maintenance higher cost in later period.Wooden bridge it is resistance to
The problems such as long property, fire prevention and limitation timber felling policy is the bottleneck for restricting its development.The bridge that stone assembles needs scene
Construction, the operation duration is longer, and it is also very troublesome that the later period scraps processing.
Chinese patent 201721135349.1 discloses a kind of assembled arch bridge, belongs to reinforced concrete arch bridge structure, packet
Include and be spliced to form arch along arch bridge length and width direction by plate pipe assembled unit, between arch and bridge floor be equipped with backfill or
Truss structure；Wherein, the plate pipe assembled unit includes the tubing in arc-shaped wave card and groove on its inside, and in tubing
Interior fill concrete, the ripple ridge orientation of arc-shaped wave card and the width of arch bridge are perpendicular.
But reinforced concrete arch bridge cost height, long construction period, sandstone consume big, unfavorable environmental protection；Also there is fewer parts
Arch bridge is steel construction arch bridge, but the steel construction of these arch bridges, based on truss structure, cost is higher；And it cannot be dismantled after scrapping
Secondary use；In addition, degree of disturbing is big, and supercrust repeated deformation is big, easy to crack when the structure for being close to road surface is steel.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of assembled irrigation canals and ditches arch
Bridge.
Specifically, the technical solution adopted in the utility model is as follows: the utility model includes left pontic and right pontic, institute

It is equipped with fixed device with the bottom of right pontic, is connected between left pontic and right pontic by attachment device.
Further, attachment device be separately positioned on left pontic and right pontic junction symmetrical multiple holes and
Connecting rod with matching.
Further, fixed device is the lockhole and steel pipe of left pontic and right pontic bottom.
Further, steel pipe is fixed by locking bar and nut with ground
Further, left pontic and right pontic are equipped with handrail conncting device.
Further, handrail conncting device is pre-buried bolt.
Further, left pontic and right pontic are coated with anti-corrosion material and are provided with tread plate.
Further, bridge floor connecting plate is additionally provided between left pontic and right pontic.
Further, bridge floor connection board ends are respectively equipped with the hole being connected with left pontic and right pontic and connecting rod.
Further, bridge floor connection plate surface is provided with tread plate.
The beneficial effects of the utility model are as follows:
1. modularization symmetric design, the production of entire bridge is can be completed in individual module mold, reduce mold investment at
This.
2. using ultra-high performance concrete as raw material, entire bridge can be mitigated significantly compared to normal concrete
Self weight, weight range can be reduced 30~50%.
3. assembled split bolt fixed form is used between bridge two halves and between cast-in-place or prefabricated ground, it can
To re-assembly recycling after repeatedly dismantling, the low solid waste discharge of effective sinking is conducive to environmental protection.
4. pouring using factory prefabricating, quality can be with stability contorting, and does not influence the construction period, reduces situ wet
Method operation and reduce the influence to environment.
5. carrying out coating by using fluorocarbon material, pore is enclosed, chloride ion and harmful substance are difficult to corrode, Du
Absolutely the decortication of the bridge surface layer accumulation of salt in the surface soil the phenomenon that, extend service life, reduce maintenance cost, improve the safety of bridge.

Specific embodiment
Understand for the ease of those of ordinary skill in the art and implement the utility model, with reference to the accompanying drawing and is embodied
Mode is described in further detail the utility model.
As shown in Figure 1, the present embodiment is that the symmetrical left pontic in left and right is made using ultra-high performance concrete UHPC material
With right pontic, modularization symmetric design, the production of entire bridge is can be completed in individual module mold, reduce mold investment at
This.
Due to using UHPC material for crossstructure, overall structure weight and overall cost are reduced, because pontic this life is not
Using reinforcing bar, so the self weight of entire bridge can be mitigated significantly compared to normal concrete, can reduce weight range 30~
50%, and load-bearing property is unaffected.
As shown in Fig. 2, the attachment device between the pontic of left and right is to be separately positioned on 2 junction of left pontic 1 and right pontic
Several symmetrical holes 41 and connecting rod with matching 42, after left pontic 1 and the installation of right pontic 2 are fixed, even
