Technical Field
The invention relates to the field of bridge engineering, in particular to on-site auxiliary protection equipment for bridge construction and an implementation method thereof.
Background
The overpass is called as a three-dimensional cross bridge, and refers to a modern bridge which is built at the junction of more than two cross roads, layered up and down and has no mutual interference in multiple directions, and comprises a sunken tunnel in a three-dimensional cross project (a bridge-shaped structure can be formed above a tunnel main body). Because the construction cost is higher, the construction is usually only carried out at the intersection between the expressway intercommunication and the urban main road or the expressway, and the main function is to ensure that vehicles in all directions can pass through quickly without being controlled by traffic lights at the intersection. The overpass is a modern bridge engineering and is basically characterized in that a plurality of layers of roads form a three-dimensional intersection in a three-dimensional space. The novel urban public transportation system is one of necessary products and urban public infrastructures of human traffic modernization and townsization of living areas, and is an indispensable important part in a modern social efficient transportation system.
In the construction process of road and bridge engineering, construction quality problems often occur, quality problems in the engineering have variability, for the surface quality problems, whether the nature of the problems can be transformed or not is further found out, and for vicious accidents which can be developed into component fracture and collapse, emergency remedial measures are taken in time. When emergency measures are planned, the following should generally be noted.
1) For quality accidents with high risk, a closed or warning area should be set up. Only after confirming that the collapse is impossible or the reliable support is carried out, the site treatment is permitted to be carried out so as to avoid the casualty of personnel.
2) For the part needing to be partially dismantled, the influence of the accident on the adjacent area structure is fully considered so as to avoid further expansion of the accident, and reliable safety measures and dismantling measures are made so as to strictly prevent new accidents caused by the treatment of the original accident.
3) Structural safety concerns are addressed by checking structural strength, stiffness and stability at the processing stage, providing reliable safeguards, and closely monitoring structural stability during processing.
4) When the structure is reinforced under the condition of no unloading, attention is paid to the influence of a processing method and construction load on the bearing capacity of the structure.
5) The effect on the structure of the additional internal forces generated in the accident process and the resulting unsafe factors are taken into full account.
