A method for rushing through construction of damaged bridges

Abstract

The invention discloses a method for rushing through the construction of a damaged bridge; in the invention, the upper bridge is erected; problems such as collapse, falling beams, and displacement of beams occur in a certain span of a single-span bridge or a multi-span bridge, and When the bridge foundation is stable and unaffected, it can be solved by using the bridge on the bridge; setting up a trough: Caodu refers to the method of using boats, rafts, amphibious vehicles or gate bridges to ferry people, vehicles and materials across the river; setting up culvert bridges ; Under the premise that the water flow is small, the depth is relatively shallow, and the water is not expected to rise in the short term, the way of burying culverts can be used to cross the river; the rescue unit has a professional rapid response team to deal with emergencies, and the response team consists of Composition of experts to deal with emergencies. In the present invention, the situation is controlled at the first time to avoid the expansion of harm, the division of labor is clear, and comprehensive preparations are made; for various possible dangers, the rescue unit establishes and trains professional groups of different types of work, including transportation, blasting, excavation, etc. Installation, installation and other division of labor.

Description

technical field [0001] The invention belongs to the technical field of road repair, in particular to a method for repairing damaged bridges. Background technique [0002] In recent years, our transportation has developed rapidly, and the number of heavy-duty and overloaded vehicles has increased, which exceeds the carrying capacity of the old bridge and aggravates the aging of the bridge. Therefore, the bridge has been damaged to varying degrees. The construction quality is not up to standard, the strength of the materials used is not enough, and the bearing capacity of the bridge cannot meet the relevant national standards. 2. The foundation of the bridge was damaged in the sun and rain, and then became unstable. 3. The arch bridge is eroded by harmful gas during operation, causing bridge damage. 4. The poor drainage capacity under the bridge causes damage to the bridge construction. [0003] However, during the construction of the road clearance process, it is usually n...

Problems solved by technology

[0002] In recent years, our transportation has developed rapidly, and the number of heavy-duty and overloaded vehicles has increased, which exceeds the carrying capacity of the old bridge and aggravates the aging of the bridge. Therefore, the bridge has been damaged to varying degrees. impact, the construction quality is not up to standard, the strength of the materials used is not enough, and the bearing capacity of the bridge does not meet the relevant national standards

2. The foundation of the bridge was damaged in the sun and rain, and then became unstable

3. The arch bridge is eroded by harmful gas during operation, causing bridge damage

4. The poor drainage capacity under the bridge causes damage to the bridge construction

When the bridge is damaged, due to the existence of rivers, affected by the flow rate and depth of the water, it is difficult to repair the work. It is necessary to ensure safety and timely transportation of personnel, mechanical vehicles and materials. The existing bridge erection method is too simple and difficult to adapt to more Emergency repair of bridges under complex conditions
