Further, when described flanged pipe collar is made up of Corrugated Steel, the annular corrugated of pipe end outer surface of its ripple and two corrugated steel tube joints matches.
Again further, when described flanged pipe collar is made up of plain plate, the inner and outer surface of described flanged pipe collar is arc surface.
Again further, it is annular corrugated that the pipe end outer surface of described corrugated steel tube joint is provided with 3～5 circles.
Described flanged pipe collar wall thickness is identical with connected corrugated steel tube wall thickness.
Described flanged pipe collar and connecting bolt, nut all carry out galvanizing by dipping processing, and when wall thickness <4.0mm, one side zinc coating layer thickness is not less than 65 μ m, and two-sided adhesion amount is not less than 915g/m
2; When wall thickness>=4.0mm, one side zinc coating layer thickness is not less than 86 μ m, and two-sided adhesion amount is not less than 1220g/m
2.Bolt, nut one side adhesion amount are not less than 350g/m
2.
Described packing ring is arranged between corrugated steel tube outer wall and flanged pipe collar inwall, for ensureing the water tightness of corrugated steel culvert, is respectively O-ring gasket, sleeve pipe packing ring and banded packing ring, and packing ring can be selected according to sealing requirements.
Described gasket materials adopts butyl rubber, neoprene or cellular rubber conventionally.
The beneficial effects of the utility model:
1) improve joint strength.The utility model adopts flanged pipe cuff to live the interface between two sections of corrugated steel tubes, has increased the body rigidity of jointing, has improved the stress performance of jointing.
2) strengthen sealability.The flanged pipe collar inwall that the utility model adopts is the ripple identical with corrugated steel tube, in the time that the ripple between flanged pipe collar and corrugated steel tube is fitted, there is certain sealability, snap in again the packing ring of quality of rubber materials, more greatly increase the sealability of culvert, finally fastening along with flanged pipe collar, by tightly compacted, ensures that corrugated steel culvert has larger pressure or level of ground water that seepage can not occur when higher between pipe collar, packing ring and corrugated steel tube three.
3) ensure durability.The flanged pipe collar that the utility model uses avoids pipe collar to be welded on corrugated steel tube, has protected the dip galvanized on corrugated steel tube surface, has ensured the durability of corrugated steel tube.
4) construction simple and fast.Flanged pipe collar of the present utility model is the integrated type pipe collar that Flange is connected with pipe collar, has reduced the operation of on-the-spot installation connecting element, has shortened the construction period.Flanged pipe collar only has an interface, has simplified the fastening working procedure of link.Can be by option interface the position on culvert circumference, avoid the unfavorable regions such as corrugated steel tube pipe shaft bottom, for bolton construction brings very big facility.
