Background
The trestle is a temporary bearing structure built on water for transporting materials, equipment and personnel, and has the remarkable characteristics of high bearing capacity, high construction speed, convenience in disassembly and assembly and the like. The steel trestle has the advantages of light structure, good integrity and small deformation, and is widely applied in the bridge construction process.
In actual construction and use, the riverbed bottom geological conditions often differ a lot, and river surface rivers impact force also can cause adverse effect to landing stage support stability, and along with the lapse of time, the deflection and the displacement volume of landing stage support increase gradually, and landing stage life reduces, and this has also caused serious threat to landing stage's structural safety. Based on this, the conventional practice is: steel members such as steel pipes and channel steels are welded between the steel pipe piles to resist relative displacement between the steel pipe piles. This approach, although simple and easy to implement, has a number of drawbacks: the prestress between the non-standard steel component and the steel pipe pile is large and is not easy to eliminate; the welding can generate larger residual stress to cause local deformation, and the welding quality is not easy to check; the welding process is time-consuming and labor-consuming, the support is inconvenient to disassemble, and the reusability of materials is damaged.
Therefore, how to realize the stability of the trestle support under the conditions of complex geology and strong water flow impact and further improve the construction efficiency of the trestle becomes the direction for improving the structural form and the construction method of the trestle.
