With the rapid development of China's economy, as represented by the highway highway sprung up, a sharp increase in road traffic, axle load of vehicles traveling on the road speed and the vehicle is growing, people driving comfort requirements also increasing, so the previous question bridge design and construction related to inadequate attention joints device becomes a more prominent, forcing the bridge design, construction, maintenance and management departments are to be fully appreciated. Highway bridge expansion joint device affiliated with other components, like bridges, with the need to bridge technological advances and applications of new varieties emerging, all aspects of performance has been further improved. Hao Tong Engineering Rubber Co., Ltd. Hengshui design and production of various types of bridge expansion joint device over the commercialization and abroad, after many years of practical application of engineering, has been fully reflected in their characteristics and shortcomings, and on the basis of summing up past experience on continuous improvement and perfection, the quality of products is also rising. Wuhan City, Hubei Province, after the Han River Bridge retractable telescopic device damage the device is a lot of water seepage, causing corrosion of steel area, the eastern ring road overpass in Tianjin plate rubber expansion device uses just one year there appeared rubber cracking, plate exposure, anchor off, affect the normal use of the bridge, Dalian City, Liaoning Province overpass steel plate telescopic device integration in the near future will be seriously damaged after telescopic device off Modular bridge expansion joints offer, anchors exposed gqf-mzl type, produced a strong jolt when the car passes side impact beams, resulting in some broken concrete girder ends, there have been holes, seriously affected the normal transportation, Liaoning Province Xianglujiao overpass, the main road northeast section of the full-length 2023m, total plate rubber expansion device 24, widespread on both sides of the broken pavement, herbs penetrate the cap bolt deformation, angle open welding bounce, rubber sheet loose modulus of rupture type bridge expansion joints, void abolished, severely damaged about 90%. Shaanxi Province and the Weihe River Bridge on the road, the traffic has not been less than four months to a higher temperature change temperatures, rubber plate full bridge stretching device uplift deformation, deformation uneven, steel and rubber stripping Modular bridge expansion joints package mail, and some have been very serious, not only affect the driving comfort, but also affects traffic safety.
