Title:
BRIDGE REINFORCEMENT SYSTEM AND DYNAMIC REINFORCEMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/077723
Kind Code:
A1
Abstract:
A bridge reinforcement system and a dynamic reinforcement method. A bridge comprises a bridge pier (1) and a bridge deck (2); and the reinforcement system comprises a top slab (10), a first precast pile (20), a first cross beam (31), a second cross beam (32), a longitudinal beam (40), a numerical control jack (50) and a controller (60). The bridge reinforcement system can jointly bear a load transmitted by the top slab (10) by means of the first precast pile (20) and the bridge pier (1), thereby preventing the bridge deck (2) and the bridge from bearing a larger vertical load. In addition, when a pressure value of a certain or some area exceeds an allowable value, the pressure value can be reduced to be within the allowable value by adjusting adjacent numerical control jacks (50) or numerical control jacks (50) in adjacent areas, such that vehicles with overweight loads can safely cross the bridge, and damage to the bridge deck (2) and the bridge pier (1) caused by direct bearing of excessive loads can be avoided. Using the bridge reinforcement system to dynamically reinforce a bridge is particularly suitable for the situation of temporarily passing vehicles with overweight loads; and the bridge reinforcement system has the advantages of convenient construction, a short construction period, rapid recycling and dismantling, all the members being recyclable, etc.
