Description
Technical Field
The utility model belongs to bridge expansion joint water drainage device field especially relates to a bridge elastomer expansion joint water drainage device is prevented.
Background
With the development of the Chinese railway industry, the progress of the related technology is driven. The bridge engineering is one of the important components of the railway engineering, related products are changed greatly, the elastomer expansion joint is popularized rapidly by means of the convenient construction mode and good technical performance, and a set of complete, advanced and strong-operability production and construction process and technology is formed. Although elastomer construction joint possesses good waterproof performance, nevertheless face long-time precipitation, expansion joint department ponding can't in time discharge, if the water level exceeds both sides retaining platform height, ponding can follow both sides and flow out, erodes bridge end face and support, also can erode both ends roof beam body gradually and lead to the fact adverse effect to the expansion joint itself if expansion joint department long-time ponding. Therefore, the improvement of the drainage capacity of the elastic body expansion joint has a great effect on improving the applicability of the elastic body expansion joint.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a drainage device is prevented to bridge elastomer expansion joint of quick drainage, extension bridge life.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a bridge elastomer expansion joint drainage preventing device, includes elastomer expansion joint, end liner, drain pipe, aqueduct, and the end liner is located elasticity expansion joint bottom, and the drain pipe vertically link up in elastomer expansion joint and end liner, and the water inlet of drain pipe is parallel with the surface course at elastomer expansion joint, and the delivery port of drain pipe links to each other with the aqueduct.
In the waterproof and drainage device for the expansion joint of the bridge elastomer, the contact part of the drainage pipe and the bottom lining is provided with the sealing material.
In the waterproof and drainage device for the expansion joint of the bridge elastomer, the sealing material at the contact part of the drainage pipe and the bottom lining is structural adhesive.
In the waterproof and drainage device for the expansion joint of the bridge elastomer, the sealing material at the contact part of the drainage pipe and the bottom lining is a rubber ring.
Both ends of the water guide pipe are connected with the bridge drainage system and are used for guiding water flowing down from the drainage pipe into the bridge drainage system.
Adopt the device of this structure, the drain pipe water inlet is parallel with the upper surface at elastomer expansion joint, the drain pipe delivery port links to each other with the aqueduct, the aqueduct links to each other with bridge drainage system, ponding on the elastomer expansion joint flows into the aqueduct through the drain pipe, flow out behind the leading-in bridge drainage system, make the elastomer expansion joint discharge fast with the ponding of bridge concrete tip, avoided ponding from both sides infiltration to beam end and pier, effectively prevented the corrosion expansion and the concrete fracture on support surface, the life of bridge has been prolonged.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
Referring to fig. 1, the bridge elastic body expansion joint waterproof and drainage device is installed between the beam bodies 51 and 52, the drainage pipe 2 vertically penetrates through the elastic body expansion joint 1 and the bottom lining 3, the water inlet of the drainage pipe 2 is parallel to the surface layer of the elastic body expansion joint 1, the water outlet of the drainage pipe 2 is connected with the water conduit 4, the sealing material at the contact part of the drainage pipe and the bottom lining is structural adhesive 6, and accumulated water on the elastic body expansion joint flows into the water conduit through the drainage pipe and flows out after being guided into a bridge drainage system. The sealing material at the contact part of the drain pipe and the bottom lining can be a rubber ring.
During construction, when the bottom lining is installed at the elastic body expansion joint, a drain pipe is installed, and a water guide pipe connected with a bridge drainage system is installed after the expansion joint is constructed. The problem of the ponding of elastomer expansion joint and bridge concrete tip is solved, life has been prolonged, has avoided ponding to ooze to beam-ends and pier from both sides down, has effectively prevented the corrosion expansion and the concrete fracture on support surface.
