Description
Technical field
The invention belongs to technical field of bridge construction, and in particular to a kind of anti-ponding structure in overhead bridge floor edge and construction
Engineering method.
Background technique
With urban economy development, overpass is alleviated city and is handed over as downtown roads capacity and level-of-service is improved
Logical pressure, facilitates the important means of citizens' activities, each big city has been more and more widely used at home.But in overpass
In use process, all there is overpass bridge floor ponding in many cities.When overhead road of city bridge construction, due to bridge floor edge pitch
Not firm out-of-flatness is rolled, bridge expanssion joint is concrete structure, is constructed after the completion of bridge floor asphalt paving, it is easy to cause
There is seeping phenomenon in overpass edge and expansion joint construction marginal position, become the main happening part of bridge floor rainwater ponding point.
Summary of the invention
The present invention to solve the deficiencies in the prior art, provides a kind of anti-ponding structure in overhead bridge floor edge and construction.
The present invention is achieved by the following technical solutions:
Gutter, gutter is arranged in overpass bridge floor edge in a kind of anti-ponding structure in overhead bridge floor edge, including roof drain
Interior placement soakaway trench, soakaway trench are connected to roof drain, are filled with graded broken stone in gutter, pave asphalt uplayer on graded broken stone；Institute
It states surrounding on soakaway trench and is uniformly provided with water seepage hole, soakaway trench is wrapped up by permeable geotextiles.
A kind of anti-ponding structure construction engineering method in overhead bridge floor edge, includes the following steps:
(1) gutter is reserved: when overpass concrete box girder construction, on overpass concrete box girder or concrete leveling layer side
Edge is pre-placed cuboid template, and pre-buried cuboid template is embedded in concrete box girder 2-5cm；It is used at expansion joint and roof drain
It is arranged to roof drain adverse slope；
(2) preliminary asphalt paving: pave pitch cutting optimal on overpass bridge floor, by cuboid mould after the completion of asphalt paving
Plate takes out, and forms gutter；
(3) soakaway trench is placed: the soakaway trench that surrounding is enclosed with permeable geotextiles is placed in the gutter in step (2)；
(4) it backfills: gutter being backfilled using graded broken stone, and vibration compacting is carried out to soakaway trench two sides；
(5) asphalt paving: using the online asphalt uplayer that paves of large-scale paver, bridge floor is specially rolled with baby roller
Edge and gutter edge, baby roller are closely followed large-scale paver vibration and are rolled 3 times or more.
As a preferred solution:
In the step (1), cuboid template is the cuboid wooden unit that longitudinal section is 10 × 10cm.
In the step (4), rubble is the graded broken stone of 0.5-1cm.
The invention has the benefit that
The present invention is by forming gutter in bridge box and beam concrete and bitumen layer edge position, placement soakaway trench in gutter,
The method for backfilling graded broken stone, guidance ponding are discharged into bridge floor roof drain by soakaway trench in rubble gutter, reduce bridge floor ponding,
Bridge deck drainage effect is improved, rainy day bridge floor environment is improved, improves safety, while reducing the processing of later period slot, is reduced
Construction cost.
Detailed description of the invention
Fig. 1 is cross section structure schematic diagram of the invention.
Fig. 2 is part planar structural representation of the invention.
In figure: 1 roof drain, 2 gutters, 3 soakaway trench, 4 graded broken stones, 5 water seepage holes, 6 asphalt uplayers, 7 pitch cutting optimals,
8 concrete box girders.
Specific embodiment
Specific embodiments of the present invention are given below, it should be noted that the invention is not limited to implement in detail below
Example, all equivalent transformations made on the basis of the technical solutions of the present application each fall within protection scope of the present invention.
The present invention is to reduce overpass bridge floor rainy day ponding, provides a kind of anti-ponding structure construction work in overhead bridge floor edge
Method includes the following steps:
(1) gutter 2 is reserved
When overpass concrete box girder 8 is constructed, it is pre-placed in overpass concrete box girder 8 or concrete leveling layer edge
Cuboid template, cuboid template used in the present embodiment are the cuboid wooden unit that longitudinal section is 10 × 10cm, pre-buried cuboid
Template is embedded in 4cm, exposed 6cm in concrete；It is arranged at expansion joint and roof drain 1 using to 1 adverse slope of roof drain.
(2) preliminary asphalt paving
Pave pitch cutting optimal 7 on overpass bridge floor, and the asphalt paving of pitch cutting optimal 7 is extremely neat with cuboid template
It is flat, rolled after the completion of asphalt paving and edge finishing after, cuboid template is taken out into recycling and facilitates next utilization, at this moment bridge
Face edge forms gutter 2.
(3) soakaway trench 3 is placed
3 surrounding of soakaway trench used is uniformly provided with water seepage hole 5, is wrapped up soakaway trench 3 with permeable geotextiles, then will
It is put into the gutter 2 formed in step (2).It before placing soakaway trench 3, will first be cleaned out in gutter 2, place soakaway trench 3
When, guarantee is straight suitable, must not generate bending, clogging.
(4) it backfills
The gutter 2 for being put into soakaway trench 3 is backfilled using the graded broken stone 4 of 0.5-1cm, and passes through the small-sized work of special messenger
Tool carries out vibration compacting to 3 two sides of soakaway trench.
(5) asphalt paving
Finally using the online asphalt uplayer 6 that paves of large-scale paver, cold joint quantity, the asphalt uplayer to pave are reduced
The 6 entire bridge floors of covering.2 edge of bridge floor edge and gutter is specially rolled with baby roller.After the completion of paving operation, small-sized pressure
Road machine is closely followed large-scale paver and is rolled 3 times to bridge floor vibration, quickly to improve compacted density in asphalt high temperature.Most
Arrange special messenger levelling to carrying out repairing around bridge floor edge afterwards, the extra mixture of edge is removed in careful filler finishing.To in bridge floor
Portion's temperature be fully lowered into after outdoor temperature can open to traffic, (about 3--7 days) the open friendship again preferably after asphalt is stablized
It is logical.
It is above-mentioned to further comprise a kind of anti-ponding structure in overhead bridge floor edge, including roof drain 1, in overpass bridge floor edge
Gutter 2 is set, soakaway trench 3 is placed in gutter 2, soakaway trench 3 is connected to roof drain 1, is filled with graded broken stone 4, graded broken stone in gutter 2
Pave asphalt uplayer 6 on 4；Surrounding is uniformly provided with water seepage hole 5 on the soakaway trench 3, and soakaway trench 3 passes through permeable geotechnological cloth bag
It wraps up in.
Rubble sewer is arranged in constructing viaduct deck to drain, bridge floor water accumulating volume can be efficiently reduced, guarantees edge construction
Quality.Raising bridge deck drainage efficiency under the premise of guaranteeing quality is realized, good environmental benefit and economic benefit are achieved.
Engineering method of the invention prolongs first stage of the project and Jinan City Industry North Road through street construction project in the overhead south Jinan Shun He
Middle test application.Compare by case history, good economic and social benefit is played, from now in urban viaduct and road
In engineering construction, which popularizes application in an all-round way.
Rubble gutter 2 is arranged in constructing viaduct deck to drain, effectively saves late maintaining maintenance cost, and can be very well
Play the role of avoid bridge floor ponding, improve the safety coefficient of bridge floor rainy day driving.
Embodiment described above, only one kind of the present invention more preferably specific embodiment, those skilled in the art
The usual variations and alternatives that member carries out within the scope of technical solution of the present invention should be all included within the scope of the present invention.
