Background technique
Along with fast development, the particularly raising of aseptic technic of steel processing technology of domestic highway, urban construction, corrugated steel culvert, with the feature of its good mechanical property and easy construction, strong adaptability, good endurance, is just progressively familiar with and is paid attention in civil engineering construction at home.Especially in recent years at home under the market environment of steel production capacity surplus, price depression, advocate energetically low-carbon (LC) traffic, energy-conserving and environment-protective and promote under the overall background of Urbanization Construction fast development in country, corrugated steel culvert has more superior cost performance and social benefit, has wide application space at the numerous areas such as highway, municipal administration.
As a kind of flexible structure, corrugated steel culvert can fully adapt to various soft foundations and unfavorable terrain.Compare with bricklaying culvert with conventional steel reinforced concrete, that corrugated steel culvert has is lightweight, bearing capacity good, adaptive deformation ability is strong, good endurance, long service life, road-ability is good, the duration is short, cost is low, be beneficial to the advantages such as environmental protection, and can carry out batch production centralized production, not affected by environment, on-the-spot easy for installation, do not need to use main equipment, can greatly improve working efficiency, reduction cost, the reduction of erection time of Culvert engineering, there is clear superiority.
Corrugated steel tube generally forms the tube coupling of certain length by hot-dip galvanizing sheet steel being processed into rolling after corrugated, during for culvert or underground utility, traditional way normally adopts band waveform long-neck Integral flange to connect.First this Placement makes the tail end with long-tail end flange the waveform of laminating corrugated steel tube, then by flange welding to corrugated steel tube outer wall and make flange and the waveform of corrugated steel tube coincide, the justify align of corrugated steel tube when site operation, complete connection by the bolt between clamp flange, between flange, be provided with sealing material to ensure the watertightness performance of structure.
Application discovery, traditional band waveform long-neck Integral flange has following deficiency:
1) destroy the hot galvanized layer of corrugated steel tube when flange welding, caused the durability of corrugated steel tube to reduce;
2) in the time that the substrate of corrugated steel culvert produces uneven settlement, the flange of docking is unfavorable for the transmission of stress between corrugated steel tube joint, easily causes flange bolt to rupture because of external pressure.
3) China's geological form complexity, usually can run into the culvert that outlet submerged culvert or level of ground water are higher, and in the time adopting welding between flange and corrugated steel tube, sealing is poor.
4) flange connection is equipped with bolt along pipe shaft circumference uniform distribution, and for the bolt of pipe shaft bottom, due to limited space, its fastening construction is inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, adopts a kind of good airproof performance, high, the easy for installation flanged pipe cuff structure connecting for corrugated steel culvert of join strength.
For achieving the above object, the utility model adopts following technological scheme: a kind of flanged pipe cuff structure connecting for corrugated steel culvert, comprise the corrugated steel tube that flanged pipe collar, liner and two joints are connected, the pipe end interface ripple of two sections of corrugated steel tubes is annular or spirality; Described flanged pipe collar is the not closed circular structure of being made up of steel plate, two ends of described flanged pipe collar jointing respectively outward flanging form flange, described two Flanges are parallel to each other, two parallel Flange corresponding surfaces are provided with some to attachment hole, every pair of attachment hole is bolted to connection, on the pipe end outer surface of the corrugated steel tube that described flanged pipe cuff is connected at two joints, described packing ring is arranged between corrugated steel tube outer wall and flanged pipe collar inwall.
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.
