公路桥梁伸缩缝构造要求 131 6657 0832
公路桥梁伸缩缝是建造公路桥梁时特意保留的构造，主要防止温度变化等因素影响公路桥梁的安全。
Highway bridge expansion joints are specially reserved structures when constructing highway bridges, which mainly prevent the temperature change and other factors to affect the safety of highway bridges.要求伸缩缝在平行、垂直于桥梁轴线的两个方向，均能自由伸缩，牢固可靠，车辆行驶过时应平顺、无突跳与噪声；要能防止雨水和垃圾泥土渗入阻塞；安装、检查、养护、消除污物都要简易方便。 在设置伸缩缝处，栏杆与桥面铺装都要断开。
Requirements of expansion joints in two directions parallel and perpendicular to the axis of the bridge, can free expansion, firm and reliable, the vehicle had to be smooth, no sudden jump and noise; to prevent rainwater and waste soil infiltration obstruction; installation, inspection, maintenance, eliminate dirt to be simple. At the expansion joint, the railing and the bridge deck should be disconnected.
