Hao-modulus formula (including post-embedded single stitch) should bridge expansion joint construction and installation of device points to note: 1, should (including post-embedded single stitch) bridge expansion joint device check reserve tank size by design Modular , embedded anchor tendons do not meet the design requirements, we must first deal with before telescopic device after installation to meet the design requirements. 2, the modulus of the formula (including post-embedded single stitch) bridge expansion device before installing, positioning value should be adjusted according to the temperature at installation during installation, with a special fixture to fix it. 3. When installed, the center line and the center line of Modular Bridge (including post-embedded single stitch) bridge expansion coincidence, and make it the top surface elevation coincided with the design elevation, according to the deck cross slope orientation, welding. 4, before pouring concrete to bridge the gap stuffer Modular expansion (including post-embedded single slit type), pouring concrete to prevent the gap closed, affecting retractable and telescopic device to prevent the infiltration of concrete displacement control box, it does not allow concrete Splashing fill in the cracks and surface sealing rubber band, if this occurs, you should remove it immediately and normal maintenance. After 5 to be the modulus of the formula (including post-embedded single stitch) bridge expansion slots reserved for anchoring concrete strength on both sides to meet the design requirements, before opening traffic.
