[Current] Views on the bridge expansion joint device is designed (1) [] small span bridge expansion joints in bridges (such as within 20m of) should be no expansion joints. Fixed bearing rubber bearing, so piers elastic deformation and soil resistance to Taiwan after the temperature stress resistance (due to deformation length within 10m telescopic amount generally less than 5mm). You can also paving the road and bridge paving over, and then open a seam along the original 3 ~ 5cm wide and 2cm deep seam false, filled with asphalt oakum or other plastic material to prevent surface cracking. (2)] [bridge expansion joints, the bridge should adopt the W-type telescopic device, it has the following advantages: ① telescopic body is coupled with iron can not glue, and the use of pre-compaction of the rubber itself waterproof seam; ② scantlings Highway 40 bridge expansion joints small manufacturers all types, corresponding to the amount of material Province, construction convenient, low cost; ③ stretching deformation temperature play like rubber elastic material properties. Under the effect of the external load is to take advantage of the arch structure. [Bridge expansion joints]. Comb comb slab slab structure for the two main jagged steel, its jagged intertwined, so when the retractable steel cross over, do not squeeze another. Vintage comb plate joints can not solve the water problem, but after the improved comb slab to solve this problem. [] Comb slab bridge expansion joints advantages:? Rugged durability. ? Driving beating small? There waterproof device will not cause leakage under the rain. ? Complex structure, easy construction, higher cost. ? When maintenance is not easy to be damaged. [] How to replace the bridge expansion joints pouring concrete anchorage zone: lane concrete bridge deck pavement bridge expansion joints should be the same [device] were pouring concrete anchorage areas while leaving construction joints are not allowed on the site and the entire deck . Strengthen conservation] [bridge expansion joints:] [bridge expansion joint device operating process must strengthen the conservation modulus C-type bridge expansion joint construction program, to create a good working environment for bridge expansion joint telescopic devices to work properly. [Fix] bridge expansion joints in the trading process remedies for damaged joints devices should be promptly repaired, replaced, in order to avoid greater losses, the specific measures are as follows: [] member local repair bridge expansion joints, replacement joints device is only a partial member does not work in the early damage, this time to repair, replace damaged parts individually, so that meet the requirements of expansion joint device work properly and can reduce losses. [] Means to repair bridge expansion joint replacement joints device has caused damage broken bridge jumping, partial repair and replacement of individual components have been impossible in a timely manner, which should replace the expansion joint device. On a large stretch of less than 50mm, the bridge is recommended TST elastomer and gravel-filled telescopic device or SD-80 telescopic device is recommended for bridge Maurer seam device (in the car can be hindered premise). Repair bridge expansion joint replacement principle [] should be based on economic rationality means the principle that is able to take advantage of the full use, can not use the complete replacement, repair replacement in order to achieve our goal. In short, the bridge expansion joints Bump issue is a more complicated issue, linked to the various aspects of the design, construction, maintenance, and therefore need to solve this problem through rigorous design, construction specifications, timely maintenance in order to solve or alleviate this a disease.
