Study On Design And Construction Of Corrugated Steel Pipe Culverts

The corrugated steel pipe culvert is essentially different from concrete culvert on the structure. The corrugated steel pipe has the fine characteristic of horizontal compensation in displacement, and use steel fully as strong stretching resistance and ascendant distortion. The steel corrugated pipe can meet the special requirement of culvert structure stress that caused by uneven distortion of the ground from permafrost and soft soil, and yellow soil expansive soil etc. So it has extensive application prospects.This paper investigates the detail information of the corrugated steel pipe culverts about the usage and the performance in inner and outer country. Combined with the experiment of the corrugated steel pipe culverts on spot, the writer carries out indoor simulations, computes the stress and strength station of corrugated steel pipe culverts in different load, different pipe diameter, different wall thickness, different wave form, different filling height. The writer finds the rules about the stress which different with different wave form and position, etc. According to the effect of he steel corrugated pipe culverts as doing experiment and the construction, the writer confirms the scope of application and suitable condition of the corrugated steel pipe culverts, which can pave on the base of the design of the corrugated steel pipe culverts in our country.This paper investigates the antiseptic method and measure of the relevant trade building structure and underground piping, corrosion research and antiseptic countermeasure of highway corrugated steel pipe culverts in the country as U.S.A.,etc. It also analyses corrosion mechanism and influence factor that corrugated steel pipe culverts in the soil, aqueous solution and atmosphere; and proposes the scheme of antisepesis of corrugated steel pipe culvers suitable for our countryAccording to the domestic construction experience and practice on the highway and railway of corrugated steel pipe culverts, this paper summarizes the construction craft of the corrugated steel pipe culverts suitable for our country, and put forward the corresponding construction requirement.
