Study On Application Technology Of Large Aperture Corrugated Steel Pipe Culverts

With the highway construction, highway reconstruction levels to improve the highway to the mountains, coastal areas such as extension of the special geological environment encountered more and more. Chicken feet ditch in the landscape, the soft base area of conventional reinforced concrete structure built culverts, when the technology channel complex, high cost, poor use of structures, culverts frequent differential settlement damage. From the materials and the structure and function of the nature of relations, using flexible, high-strength steel corrugated metal pipe culvert, not only has to adapt to deformation of the foundation and basis for the ability to solve differential settlement due to foundation problems caused by culvert damage.Corrugated metal pipe culvert is a corrugated tube or by the use of corrugated board by connecting arc, the formation of a culvert in the form of assembly. Bellows made of steel, aluminum or plastic materials. Steel corrugated metal pipe culvert due to the presence of axial corrugated excellent mechanical characteristics, while the axial and radial distribution of stress and strain caused by load, distributed load can be greater stress concentration, better play steel advantage. Especially in the soft soil, expansive soil, loess soil areas such as poor work, using structural steel corrugated pipe culvert construction has more advantages, but also a more broad application prospects.This paper intends on 6 meters of lcorrugated steel structure, high fill embankment in different basic conditions and heavy vehicle loads to study the stability and, based on bellows testing before the construction of culvert, construction technology and construction technology from the perspective of the study concluded.Corrugated steel pipe culvert proposed to adapt the scope, terms of use, selection principles, as well as for different occasions Hebei corrosion program and technical requirements.
