Maintenance and reinforcement method for road expansion joint

The invention discloses a maintenance and reinforcement method for road expansion joint. The method comprises the following steps that step 1, stopping traffic flow; step 2, dismantling an original device in the expansion joint; step 3, reserving and fastening the anchoring part; step 4, arranging an elastic connecting plate at the bottom end of the expansion joint; step 5, arranging a first fixing part and a second fixing part which are connected with the anchoring part in the expansion joint, and arranging the X-shaped plate between the first fixing part and the second fixing part; step 6, arranging an elastic supporting plate between the first fixing part and the second fixing part, and arranging a template on the elastic supporting plate; step 7, pouring cement concrete on the outer side of the formwork, and laying a fixing pressing plate and a magnetic cover plate after curing; and step 8, symmetrically arranging movable push plates at the two ends of the magnetic cover plate, and arranging dust collection systems at the upper ends of the movable push plates. An original device is eliminated, maintenance and reinforcement are fundamentally carried out, the later maintenance frequency is reduced, the trouble of multiple reinforcement is avoided, and the deformation stability of the expansion joint is guaranteed.

本发明公开了一种道路伸缩缝维修加固方法，包括以下步骤：步骤一、中止交通流；步骤二、拆除伸缩缝内的原有装置；步骤三、保留锚固件并紧固；步骤四、伸缩缝底端设置弹性连接板；步骤五、伸缩缝内设置与锚固件连接的第一固定部和第二固定部；X型板设置在第一固定部和第二固定部之间；步骤六、在第一固定部和第二固定部之间的设置弹性支撑板，弹性支撑板上设置模板；步骤七、模板的外侧浇筑水泥混凝土，养护后铺设固定压板、磁性盖板；步骤八、磁性盖板的两端对称设置可移动推板，可移动推板的上端设置吸尘系统。本发明剔除原有装置，从根本上进行维修加固，减少以后的维修次数，避免多次加固的麻烦，保证了伸缩缝形变的稳定性。
