First, on the front joints construction joints during construction programs 1. To reserve tank size by design check and reserve tank cleaned. After expansion joints before installation of embedded anchor tendons do not meet design requirements, we must first deal with, meet the design requirements. 2. Before installing the expansion joint assembly should be adjusted according to the positioning value is calculated based on the actual design drawings in temperature, with special fixtures to secure them. 3. Install the center line of the bridge expansion joints should overlap the center line, and its top surface elevation and design elevation consistent, and cross slope, longitudinal and transverse slope deck, longitudinal match. 4, properly seated, and then put through a lateral coupling horizontal bars, preferably anchor bars with embedded steel expansion joint on both sides of the weld at the same time, if difficult, the first side of the weld, has been determined to be reached Installation temperatures after anchoring the other side all the weld reinforcement and relax fixtures to stretch freely. 5. After completing the above steps, should be pouring concrete in the reserved slot, pouring concrete to take the necessary measures, vibrating compaction. Pouring concrete is not allowed splashing, fill in the cracks and surface sealing rubber band, and if this occurs should be immediately removed. Conservation after pouring is completed. 6. After the expansion joints on both sides of the concrete strength to meet the design requirements, before they open traffic.
