Rapid assembly type steel corrugated plate arch bridge adaptable to large foundation displacement

Abstract

The invention relates to a rapid assembly type steel corrugated plate arch bridge adaptable to large foundation displacement. Most corrugated bridge culvert foundations are constructed through cast-in-place concrete, and the site construction efficiency is quite low. The rapid assembly type steel corrugated plate arch bridge adaptable to large foundation displacement comprises an arc-shaped culvert body and a concrete foundation. The culvert body is formed by connecting a plurality of arch culvert units in the axial direction, and each arch culvert unit is formed by splicing a plurality of sections of corrugated plates in the circumferential direction. Corrugated plate pins are arranged at the bottoms of the two ends of each arch culvert unit. A base is arranged on each steel corrugated plate pin. The concrete foundation is formed by assembling a plurality of concrete blocks in the axial direction, and embedded parts arranged in the concrete foundation are fixed on the bases. According to the rapid assembly type steel corrugated plate arch bridge adaptable to large foundation displacement, manufacturing and installing of the steel corrugated plate arch bridge are convenient, the construction period is shortened, and the engineering cost is reduced; in addition, the rapid assembly type steel corrugated plate arch bridge can be adapted to large foundation displacement, and the use requirements of bridge culverts are met; and the rapid assembly type steel corrugated plate arch bridge is suitable for the areas needing special foundations, such as a soft soil foundation, a swelling soil foundation, a frozen and thawed soil foundation and a collapsible loess foundation, and can meet the rapid construction requirements of disaster prevention and reduction and emergency rescue.

Description

technical field [0001] The invention belongs to the technical field of traffic construction, and in particular relates to a rapidly assembled steel corrugated plate arch bridge that can adapt to large displacements of the foundation. Background technique [0002] As a typical space structure, steel corrugated plate bridges and culverts have the advantages of high strength, good durability, good mechanical performance, strong deformation resistance, simple construction, short construction period, and Beautiful and other characteristics, has become the main way of highway bridges and culverts. How to give full play to the advantages of good flexibility and high strength of steel bellows, especially in areas with special foundations such as soft soil, expansive soil, freeze-thaw soil, and collapsible loess, as well as in disaster prevention, disaster reduction, emergency, Playing its irreplaceable role in emergency rescue has become a research hotspot for bridge and culvert de...

AI Technical Summary

Problems solved by technology

[0003] Most of the foundations of traditional corrugated slab bridges and culverts are made of cast-in-place concrete, which requires on-site management and concrete maintenance, especially in areas with harsh environments where construction is difficult and the overall construction efficiency is low

Moreover, in some special environmental areas with uneven settlement, the adaptability of traditional concrete foundations is poor, resulting in damage to the joints of steel bellows, which seriously affects the performance of corrugated steel culverts
