Construction Organization Optimization
Construction in different time periods: Priority should be given to nighttime or low traffic periods to reduce interference with daytime traffic.
Segmented homework: Divide the bridge into multiple construction sections, replace the bearings section by section, and avoid the entire bridge being closed.
Rapid construction: Automated lifting equipment (such as SPLC-8 fully automatic hydraulic control lifting system) is used to shorten the single operation time.
Technological upgrade
Synchronous lifting technology: Multiple lifting points are controlled by a computer to ensure the smooth and stable lifting of the beam, avoiding local stress concentration.
Non deformable rigid bracket: protects the appearance of the beam and prevents damage to the bridge structure during lifting.
Quick repair of epoxy mortar: Within 3-5 hours after replacing the support, reach C30 strength and shorten the curing time.
Strengthening traffic management
Traffic control: Set up temporary speed limits, lane closure signs, and implement half width construction if necessary.
Emergency evacuation: equipped with night warning lights, reflective cones, and develop emergency plans for traffic accidents.
Departmental collaboration: Jointly develop traffic evacuation plans with traffic police and road administration departments to ensure complete approval procedures.
Case Reference
SPLC-8 fully automatic hydraulic control lifting system: Through computer control of multi-point lifting, the bridge can be lifted synchronously as a whole, suitable for bearing replacement without interrupting traffic.
Non deformable rigid bracket: protects the appearance of the beam and prevents damage to the bridge structure during lifting.
Through the above measures, the impact of bearing replacement on traffic can be significantly reduced, ensuring construction safety and traffic efficiency.
