Description
Technical field
The utility model is related to a kind of expanded joint structure, more particularly to a kind of bridge deck expansion joint structure.
Background technology
Since reform and opening-up, Urbanization in China is quickly grown, but most cities public transportation construction is fallen relatively
Afterwards, increasing with various vehicle fleet sizes, traditional level crossing mode of transportation have become " the road cancer " of urban transportation, serious to make
The about process of urbanization.Under severe traffic form, urban viaduct this " air traffic " comes into being, script usual friendship road
The replacing vehicle of mouth is made the river on different elevations and is flowed, and takes their own roads, does not interfere with each other, to improve speed and road passage capability,
Urban traffic pressure has been effectively relieved.However, some newly-built overpass are open to traffic occurred as soon as damage less than 1 year, wherein most often
It is exactly Moisture Damage to see, endanger maximum；Particularly with asphalt concrete bridge surface, since its porosity is higher, poor waterproof properties, water
It penetrates into and is trapped in concrete voids, under the comprehensive function of the factors such as temperature, load, not only cause loose, the stripping of face layer
It falls and is destroyed with pit slot, and seriously affected the durability of bridge deck structure.
Utility model content
The purpose of the utility model is to overcome the defect of the prior art, a kind of bridge floor of guarded drainage better performances is provided and is stretched
Contracting crack structure, what the technical solution of the bridge deck expansion joint structure was realized in：
A kind of bridge deck expansion joint structure, includes the floorings at expansion joint and expansion joint both sides, the floorings from lower and
On include successively armored concrete main panel, concrete leveling layer, waterproof layer and asphalt concrete pavement, use in the expansion joint
Styrofoam is filled, and the expansion joint top surface is provided with telescopic device, and the floorings top of the expansion joint both sides is reserved with flexible
Preformed groove is stitched, fiber concrete is poured after the expansion joint preformed groove is interior, expansion joint preformed groove both sides are additionally provided with infiltration leakage
Pipe.
Further, the waterproof layer is sealed with expansion joint preformed groove junction with sealing material.
Further, the waterproof layer is 1.5mm thickness polyurethane water-proof layers.
Further, the asphalt concrete pavement includes top 40mm thickness particulate formula modified asphalt concrete layers and lower part
Middle grain formula modified asphalt concrete layer after 50mm.
Further, the infiltration fistulae is set to asphalt concrete pavement and concrete leveling layer intersection, passes through weldering
It is fixed on the armored concrete main panel in the bail on the infiltration fistulae.
Further, the discharge outlet periphery of the infiltration fistulae is provided with row's infiltration hole, and the ponding for that will penetrate into converges
Enter discharge in the infiltration fistulae.
The expanded joint structure of the utility model is provided with expansion joint preformed groove, and fiber concrete is poured after and fixes expansion joint group
Part is closed in the waterproof layer end of expansion joint both sides using sealing material filling to avoid bridge floor water from flowing to waterproof layer along gap,
Since there is bridge floor bituminous concrete permeability performance, infiltration easily to flow to the concrete base side filled in flexible slot and stagnant
It stays, accumulates in the moisture near flexible slot for discharge, infiltration fistulae is provided with beside bridge expanssion joint, expansion joint will be flowed to
Water export.
The bridge deck expansion joint structure of the utility model is simple in structure, firm and reliable connection, guarded drainage better performances, Neng Gouyou
Effect improves the durability of bridge deck structure.

When it is implemented, the waterproof layer 1 is sealed with 7 junction of expansion joint preformed groove sealing material 2.
When it is implemented, the waterproof layer 1 is 1.5mm thickness polyurethane water-proof layers.
When it is implemented, the asphalt concrete pavement 4 include top 40mm thickness particulate formula modified asphalt concrete layers and
Middle grain formula modified asphalt concrete layer after the 50mm of lower part.
When it is implemented, the infiltration fistulae 12 is set to asphalt concrete pavement 4 and 5 intersection of concrete leveling layer,
It is fixed on the armored concrete main panel 8 by the bail 10 being welded on the infiltration fistulae 12.
When it is implemented, 11 periphery of discharge outlet of the infiltration fistulae 12 is provided with row's infiltration hole, for what will be penetrated into
Ponding imports discharge in the infiltration fistulae 12.
The technology contents and technical characteristic of the utility model have revealed that as above those skilled in the art still may base
The replacement and modification without departing substantially from the utility model in essence are made in the teaching of the utility model, therefore, the utility model protection
Range is not limited to the revealed content of embodiment, also includes various replacements and modification without departing substantially from the utility model in essence.
