Poured between the crash bearer of the first plank both sides and correspondence side and solidify to form the first lightweight concrete layer；And the
The first lightweight concrete layer of one plank both sides forms two-way downward-sloping horizontal wall inscription；Toe position and the drainpipe of crash bearer
Spilled water hole lower edge is alignd, and the seam of 1 × 1cm is reserved at toe, is clogged with polyurethane sealant；
First lightweight concrete layer top surface is equipped with a SBS waterproof rolls；
The second plank is provided with first SBS waterproof rolls, the second plank is vertically set；Second plank and first
The vertically aligned setting of plank；Poured between the crash bearer of the second plank both sides and correspondence side and solidify to form the second lightweight
Clogged with vinylacetic acid cellucotton in concrete layer, gap；
The top surface of the second lightweight concrete layer and side are coated with the 2nd SBS waterproof rolls；
The outside of the second lightweight concrete layer and the crash bearer of correspondence side are provided with french drain, and french drain Bian is wrapped up with geotextiles
Big particle diameter gravel；
The top surface of the 2nd SBS waterproof rolls top surface and french drain is equipped with planted agent mortar and Footpath brick successively；
Antiglare shield is installed on the Footpath brick.
Further, the thickness of the first lightweight concrete layer is 20cm~40cm, and the top surface gradient is not less than 2%；Institute
The gradient for stating drainpipe is not less than 1%.
The bridge central partition that the present invention is provided suppresses side bar flange plate, web and receives water by way of stifled row combines
The generation of disease is corroded, bridge member durability is effectively improved.The isolation of bridge center is by central partition inside beam body
Seam pastes ethylene vinyl acetate cellucotton, effectively suppresses the infiltration of water；Polyurethane closed glue is used to central partition interior construction seam
Closing, two-way horizontal wall inscription is formed by pouring lightweight concrete, and laying water-proof coiled material sets up the system of french drain, water leaking-in is discharged
Central partition, and along deck paving slope discharge bridge zone in length and breadth, make central partition not ponding, impermeable, lifting bridge is durable
Property.
