Technical Field

[0001] The utility model relates to the technical field of steel trestle abutments, in particular to a simple and efficient steel trestle abutment rapid erection structure. Background Art

[0002] Steel trestles are temporary structures used for bridge construction. They are mainly used in the construction of large and medium-sized offshore bridge projects to facilitate the transportation of raw materials, machinery and equipment, and workers. It is a temporary bridge facility composed of piers and beam span structures that can directly serve the construction. Steel trestles usually use prestressed tendons made of high-strength steel. By using the prestressing method, they can give full play to their bearing capacity, which is equivalent to replacing part of ordinary steel with high-strength steel, thereby saving steel. This structural form is not only suitable for bridge construction, but also for the construction of urban roads and highways, railways, ports and docks, industrial facilities, and temporary bridges.

[0003] The assembly and disassembly of steel trestles are relatively fast and can quickly meet temporary traffic needs. Their corrosion resistance and stability enable them to withstand large amounts of traffic and the load of heavy vehicles in various environments. In the past, steel trestles used a whole row of steel pipe piles for retaining soil, or cast concrete abutments for retaining soil. The construction cost was high, the construction period was long, and the concrete abutments could not be recycled, which consumed a lot of resources and was not conducive to environmental protection requirements.
