AI Technical Summary

Technical Problem

The existing soil-covered corrugated steel plate arch bridge foundation has poor adaptability to the uneven settlement, the overlying soil layer has too large self-weight, and insufficient leaping ability.

Method used

A two-way stiffened soil-covered corrugated steel plate arch bridge containing waste tire fragment filler is used to improve the adaptability and load-bearing capacity of the structure by changing the arch seat type, filling compressible lightweight filler and strengthening the arch ring.

Benefits of technology

It significantly improves the foundation adaptability, light structure weight and strong leaping ability of the soil-covered corrugated steel plate arch bridge, shortens the construction period, and realizes the recycling and reuse of resources, which is in line with the concept of ecological and environmental protection.

Abstract

The invention discloses a two-way stiffening earthing corrugated steel plate arch bridge containing waste tire fragment filler. The arch bridge is composed of a steel skewback, a corrugated steel plate arch ring, a corrugated steel web stiffening arch, a corrugated steel web stiffening beam, a steel bracket, an angle steel connecting piece, a reinforcing piece, waste tire fragments, compacted sand and a bridge deck. The waste tire fragments are light in dead weight and compressible, the positive soil arch effect can be easily formed, the deformation and stress level of the corrugated steel plate arch ring is greatly reduced, meanwhile, solid waste recycling is achieved, the influence on the environment is extremely small, and the concept of ecological environmental protection is met. The steel skewback can greatly reduce the stress of the foundation, is suitable for differential settlement of the foundation, and greatly strengthens the applicability of the arch bridge in bad foundations; the steel bracket is suitable for connection of corrugated steel web stiffening beams and stiffening arches with any wing plate width and corrugated steel plate arch rings. Rigidity, buckling resistance and bearing capacity of the corrugated steel plate arch ring are remarkably improved through the corrugated steel web stiffening beams and the stiffening arches which are arranged in a crossed mode, and the spanning capacity of the arch bridge is greatly enhanced.
