维修与保养
Maintenance and Service
1、 经常清扫橡胶带内的泥沙和石屑等杂物，防止橡胶带损坏造成漏水，如有损坏应及时更换。
1. Remove the foreign materials, such as sand and chip, in the rubber stripe at regular intervals, so as to prevent from damaging the rubber stripe. In case of damage, replace the rubber stripe in time.
2、 经常检查伸缩装置上平面是否平整，若平整性太差，或过车时发生明显刚性冲击，则很可能是滑动支承或压紧支承有损坏，也可能是支撑箱底部混凝土出现破坏，这些情况都必需尽早进行处理，否则伸缩装置将很快产生剧烈的损坏，导致无法通过维修恢复正常使用功能。
2. Check the flatness of the surface under which the expansion joint is installed at regular intervals. If the flatness is poor or noticeable rigid impact is produced when a vehicle passes over it, the sliding bearing, pressing bearing or concrete at the bottom the bearing box may be damaged. In this case, the fault shall be removed as soon as possible; otherwise the expansion joint is seriously damaged soon, and the expansion joint cannot be restored through maintenance.
3、 经常检查各缝是否均匀，若各缝间距太大，可能是位移弹簧有损坏，应及时更换。
3. Check each expansion joint for evenness at regular intervals. In case of excessive gap, the displacement spring may be damaged, and shall be replaced as soon as possible.
4、 在更换橡胶带时，还应检查钢梁的防锈情况，必要时应除锈并重新油漆。
4. Check the steel sills for rust during replacement of rubber band, and remove rust and apply coating if necessary.
