Abstract
The utility model provides a cover corrugated metal pipe of scribbling polyurea, including the tubular metal resonator bellows, the corrugated metal inside pipe wall adheres to there is the inside lining, corrugated metal outside of tubes wall adheres to there is the outer lining, the inside lining the outer lining attach through spraying or pressure or the extrusion molding mode with corrugated metal inside pipe wall zonulae occludens, the internal surface of inside lining is levelly and smoothly smooth. The utility model is used for prevent that the corrugated metal pipe is because of receiving the live time that corrodes and wear and tear damage, extension corrugated metal pipe, the inside lining material can corrosion prevention nature sewage the corruption, inside and outside lining material has certain hardness and surface smooth, adopts the design of culvert, has reduced later maintenance's work load, the wearing and tearing of the grit that can significantly reduce have also improved displacement and drainage speed effectively, the utility model discloses simple structure, corrosion -resistant and abrasionproof decrease respond wellly, have reduced later maintenance's work load, and the cost is reduced is can widely used novel pipeline in highway, mine and the municipal works.
Description
Technical field
This utility model relates to a kind of metal bellows for pipeline, culvert in the engineerings such as highway, municipal administration, railway, is specially a kind of metal bellows covering and being coated with polyureas.
Background technology
Progress along with technology, metal bellows is applied in large quantities in the engineerings such as highway, municipal administration, railway, metal bellows is mainly used in the construction of pipeline and culvert, finds through using, the well damage of the metal bellows in some pipelines, culvert, service life is short, directly affects the service life of pipeline and culvert, it has to change in advance, not only add quantities and maintenance frequency, also have impact on road traffic, add expense.Tracing it to its cause, first, some metal bellowss applied in highway, municipal works are responsible for the function drained the sewage away, and some severe corrosive sewage are serious to metal bellows corrosion failure, shorten the service life of pipeline；Secondly, using in metal bellows in highway engineering, particularly the longitudinal gradient of the culvert of mountain highway is big, and flow rate of water flow is high, is mingled with sandstone in current, and the pipeline ancient piece of jade, round, flat and with a hole in its centre wear erosion of the metal bellows in culvert is serious, directly affects the service life of pipeline and culvert.Additionally, in use also find, the ripple of metal bellows directly affects the roughness of pipeline, affects displacement, is also need to improve.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, it is provided that a kind of metal bellows covering painting polyureas.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model provides a kind of metal bellows covering and being coated with polyureas, including metal tube corrugated tube, it is characterized in that, described wavy metal inside pipe wall is attached with liner, described metal bellows outer wall is attached with outer lining, described liner, described outer lining are by spraying or press attached or extrusion molding mode and described wavy metal inside pipe wall compact siro spinning technology, the inner surface flat smooth of described liner.
As a kind of optimal technical scheme of the present utility model, the thickness that described liner, described outer lining are attached on described metal bellows inside and outside wall be described liner, described outer lining surfaces externally and internally apart from the inner side crest 1-150mm of described metal bellows ripple, described liner, described outer lining length identical with the duct length of described metal bellows, the material of described outer lining is polyureas.
As a kind of optimal technical scheme of the present utility model, described metal bellows range for 300-10000mm, pitch of waves 68-500mm, wave height 13-600mm across footpath.
As a kind of optimal technical scheme of the present utility model, described metal bellows be configured to welding or plate splicing.
This utility model reaches to provide the benefit that:
This utility model adopts metal bellows and interior outer lining coatings combine structure, the inside and outside lining material matter of metal bellows is possible to prevent the corrosion of corrosivity sewage, inner lining material has certain hardness and smooth surface, it is possible to greatly reduce the abrasion of sandstone, is also effectively improved displacement and drainage speed.This utility model simple in construction, anticorrosion and anti-wear respond well, meet requirement projected life of culvert, decrease the workload of later maintenance, reduce cost, be can widely used novel pipeline in highway and municipal works.
