Description

Technical Field

[0001] The invention belongs to the technical field of bridge pier emergency repair devices, and in particular relates to a novel modular rapid emergency repair pier. Background Art

[0002] As of November 2023, the national railway operating mileage will reach 155,500 kilometers. The total length of high-speed railway bridges currently completed and under construction accounts for more than 50% of the lines. The proportion of bridges on lines such as the Beijing-Tianjin Intercity Railway and the Beijing-Shanghai High-Speed ​​Railway is as high as more than 80%. Bridges have become the main body of high-speed railway projects. According to statistics from relevant departments of the China Railway Corporation, railway bridges are increasingly suffering from sudden disasters of varying degrees, especially railway bridges overpassing highways. Because the clearance under the bridge is mostly less than 5m, and large highway trucks are driven by economic interests, overweight and over-high loading are common, resulting in frequent collisions of overpassing railway bridges.

[0003] After a railway bridge is hit by a highway truck, the beam and pier are most likely to be damaged. When the damage is not serious, the solution of first opening and then repairing is usually adopted to minimize the loss and impact, that is, first set up temporary piers under the beam to share the force of the damaged pier or reduce the span of the beam to increase the bearing capacity of the damaged beam, so that the damaged bridge has the ability to pass at a limited speed. After the bridge is fully repaired, the damaged beam or pier will be replaced and repaired. Temporary piers are a very important emergency repair structure for railway bridges. Their warehouse transportation and on-site assembly efficiency directly affect the timeliness of the damaged railway bridge to resume traffic. However, the existing railway pier repair equipment generally has the disadvantages of strong structure but large rod volume, complex structure, slow warehouse assembly speed, etc., which is not conducive to the rapid opening of damaged railway bridges.

[0004] To this end, we provide a new type of modular rapid repair pier to solve the above problems. Summary of the invention
