Step 3), two width bridge preset slots, the continuous gap and beam body expansion joint between of beam body bridge floor are used into asphalt mixtures modified by epoxy resin
Fat glue vinylacetic acid cellucotton is jumped a queue closing；
Step 4), two width bridge preset slot tops set the first plank, pour ground floor lightweight concrete and formed
Two-way horizontal wall inscription, toe position is alignd with the spilled water hole lower edge of the drainpipe of crash bearer, the seam of the reserved 1 × 1cm of concrete at toe,
Clogged with polyurethane sealant；
Step 5), in ground floor lightweight concrete upper berth ground floor SBS waterproof rolls；
Step 6), the second plank is set on ground floor SBS waterproof rolls, the second plank and the first plank are vertically
Alignment is set；Then second layer lightweight concrete is poured, and gap is clogged with vinylacetic acid cellucotton；
Step 7), with second layer SBS waterproof rolls by second layer lightweight concrete wrap up；
Step 8), in second layer lightweight concrete both sides, french drain is set, french drain Bian wraps up big particle diameter gravel with geotextiles；
Step 9), laying planted agent mortar and Footpath brick, and on Footpath brick reserve concrete longitudinal direction anchor band, install it is anti-dazzle
Plate.
Further,
The thickness of the ground floor lightweight concrete is 20cm~40cm, and the top surface gradient is not less than 2%；
The gradient of the drainpipe is not less than 1%.
The reparation remodeling method of the bridge central partition for providing of the invention, the method presses down by way of stifled row combines
Side bar flange plate processed, web are produced by water erosion disease, effectively improve bridge member durability.The method by center every
Ethylene vinyl acetate cellucotton is pasted from band inside beam body movement joint, while release beam body deforms, effectively suppresses the infiltration of water；Centering
Isolation strip interior construction seam in centre forms two-way horizontal wall inscription using the closing of polyurethane closed glue by pouring lightweight concrete, and laying is anti-
Water coiled material, sets up the system of french drain, and water leaking-in is discharged into central partition, and bridge zone is discharged on slope in length and breadth along deck paving, in making
Entreat isolation strip not ponding, impermeable, lifting bridge durability.

Specific embodiment
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
For problems of the prior art, the present invention provides a kind of reparation remodeling method of bridge central partition,
The method is effectively sealed not only for gap so that whole central partition turns into a closed space, more passes through
The water guiding discharge central partition that effective manner will be penetrated into.Fig. 1 is referred to, the figure shows the bridge provided according to the present invention
The bridge central partition structural representation repaired after remodeling method construction of beam central partition.
In a kind of specific embodiment, the invention provides a kind of reparation remodeling method of bridge central partition,
It comprises the following steps：
Step 1), face brick, antiglare shield 12, crash bearer 1 and the former fill concrete of removing former bridge central partition to master
Top surface of the beam；
Step 2), both sides install crash bearer 1, the built-in drainpipe 2 of the crash bearer 1, the drainpipe 2 in the horizontal direction to
Under be obliquely installed；The preset slot of crash bearer 1 is closed with polyurethane sealant；
Step 3), two width bridge preset slots, the continuous gap and beam body expansion joint between of beam body bridge floor are used into asphalt mixtures modified by epoxy resin
Fat glue vinylacetic acid cellucotton is jumped a queue closing；
Step 4), on two width bridge preset slot tops, the first plank 3 is set, pour ground floor lightweight concrete 4 and shape
In pairs to horizontal wall inscription, toe position is alignd with the spilled water hole lower edge of the drainpipe 2 of crash bearer 1, the reserved 1 × 1cm of concrete at toe
Seam, clogged with polyurethane sealant；
Step 5), in the upper berth ground floor SBS waterproof roll 5 of ground floor lightweight concrete 4；
Step 6), the second plank 6 is set on ground floor SBS waterproof rolls 5, the second plank 6 is with the first plank 3 along vertical
