Bridge expansion and contraction joint is used to meet the requirements of bridge floor deformation, usually be set between two beam-ends, between beam-end and bridge abutment, or on the hingejoint of bridge. It demands the expansion and contractionjoint to free stretch out and draw back, fastness and reliable, smooth without kick and noise when vehicles pass through. To prevent rain and garbage soil infiltration causing block. The installation, inspection, maintenance, remove dirtetc. Are simple and convenient.
Specification for bridge expansion and construction joint :
According to the property and installation method, the expansion and contraction joint could be
Classified to: GQF-C Type, GQF-Z Type, GOF-L Type and GQF-F Type.
I. Rubber is elastic, easy to paste, could meet the requirement of deformation and has water
2. The structure is simple, installation is easy, reliability, comfortable and durability. Easy to re
Place the old expansion and contraction joint, also could be used for the new bridge
3. Good waterproof performance, shock absorption, not sensitive to the construction error of the
Beam-end clearance, long service life, automatic cleaning the inside seam rubbish, less mainte
Nance and low cost
Suitable for the bridge construction project of high-grade highways and urban main road.

FAQ What is geosynthetics ? Geosynthetics form a perfect erosion control fabric used extremely widely in civil engineering to stabilize and reinforce slopes and soil under or next to roads, railways, dams, water reservoirs etc.. They can be easily applied which minimizes the time of construction, as well as they limit the resources and materials necessary. What kinds of geosynthetics we have ?
