Blocking and protecting device and method for asphalt expansion joint of bridge floor
The invention belongs to the technical field of bridge construction operation, and particularly relates to a blocking and protecting device and method for a bridge deck asphalt expansion joint. According to the technical scheme, the blocking and protecting device at the bridge deck asphalt expansion joint comprises a width adjusting mechanism, side edge blocking mechanisms are connected to the two sides of the width adjusting mechanism correspondingly, and a plurality of height adjusting mechanisms for supporting the side edge blocking mechanisms are arranged below the side edge blocking mechanisms; the height adjusting mechanism is arranged in a groove, close to the expansion joint, of the prestressed concrete box girder; the device further comprises a platform which is in lap joint with the two side edge blocking mechanisms. The invention provides a blocking and protecting device and method for preventing asphalt paved on a prestressed concrete box girder from entering an expansion joint.
本发明属于桥梁施工作业技术领域，特别涉及一种桥面沥青伸缩缝处的挡护装置及方法。其技术方案为：一种桥面沥青伸缩缝处的挡护装置，包括宽度调节机构，宽度调节机构的两侧均连接有侧边阻挡机构，侧边阻挡机构下方设置有若干支撑侧边阻挡机构的高度调节机构，高度调节机构设置于预应力混凝土箱梁靠近伸缩缝出的凹槽内；还包括平台，平台搭接于两个侧边阻挡机构上。本发明提供了一种避免在预应力混凝土箱梁上摊铺的沥青进入伸缩缝的挡护装置及方法。
