Wave dissipation and scour prevention device for slab-pile bridge and construction method thereof

Abstract

The invention discloses a wave dissipation and scour prevention device for a slab-pile bridge and a construction method thereof. The structure part of the wave dissipation and scour prevention device comprises pipe piles, steel hoops, straining beams and wave blocking assemblies which are arranged at intervals. The steel hoop is correspondingly embedded in the pipe pile, the straining beam is correspondingly arranged on the outer side of the section, where the steel hoop is embedded, of the pipe pile in a sleeving mode, and the pipe pile is connected with the straining beam through the steel hoop. One end of the straining beam is connected with the wave blocking assembly, the wave blocking assembly comprises a pile body wave blocking plate and a midspan wave blocking plate which are spliced with each other, and the pile body wave blocking plate and the straining beam are of an integrated structure. The manger board and the two rows of pipe piles on the outer side of the slab-pile bridge form an integral structure, the structural stability is good, and wave impact force and uplift force can be effectively resisted; all the assemblies can be prefabricated and built in an assembled mode, the construction cost is low, and good economic benefits and application and popularization values are achieved.

Description

technical field [0001] The invention is applied to the field of wave elimination and anti-scouring of bridges, and in particular relates to a wave-eliminating and anti-scouring device for pile-slab bridges and a construction method thereof. Background technique [0002] With the urgent need for green road construction in my country's coastal areas, more and more new prefabricated pile-slab bridge structures are being promoted. However, the impact of marine environment cannot be ignored in the application of pile-slab bridge structures in offshore highway construction. The impact of waves in the offshore environment and the erosion of ocean currents seriously threaten the structural safety of bridges. To realize the application of pile-slab bridges in offshore environments, it is necessary to propose economical and effective wave dissipation and anti-scour measures and construction methods. [0003] At present, the common wave dissipation measure is to build a breakwater far ...

AI Technical Summary

Problems solved by technology

[0003] At present, the common measure for wave dissipation is to build a breakwater far away from the structure to form a sheltered water area behind the dike, but this method needs to occupy a large area of ​​sea area, and the breakwater itself does not directly have the function of anti-scouring, and needs to be constructed separately from the anti-scouring structure , a large amount of construction, contrary to the concept of green road construction
