Background technique
Steel band reinforced polyethylene spiral ripple pipe road is mainly applicable to various draining and the drainage of the uses such as municipal administration, industry, agricultural and traffic engineering construction.In the last few years along with the expanded demand in market and the needs of development of company, steel band reinforced spiral ripple pipe production line was in continuous increase, and the output of steel band reinforced spiral ripple pipe also can progressively increase.Steel band reinforced polyethylene spiral ripple pipe have corrosion resistance, surface friction drag low, resistance to wear, also there is higher ring stiffness, and the advantage such as integral forming technique is good.This kind of tubing has become the bright spot of investment of current large-bore plastics tubing, and this tubing will become the main product of China's plastic underground pipeline.But some special bury condition underground under, if the piping laying such as seashore, marsh is lower than sea level or when being in the burying underground in environment of similar hydrostatic pressing, pipeline lining polyethylene can depart from steel strip reinforced skeleton (as shown in Figures 2 and 3), outer layer polyethylene is departed from Steel Skeleton by wave trough portion after the shear failure of steel band ripple pin with inner layer polyethylene, pipeline entirety is destroyed, lose draining dirt eliminating function, the accident such as cause that road surface subsides.
In prior art, if the patent No. is 201210368014.X, name is called steel band reinforced polyethylene spiral ripple pipe disclosed in steel band reinforced polyethylene spiral ripple pipe and production method thereof, steel mesh is welded between the bipod of V-type steel band, but above-mentioned structure can not solve outer layer polyethylene is departed from Steel Skeleton with inner layer polyethylene problem by wave trough portion after the shear failure of steel band ripple pin, number of patent application is 201410606315.0, name is called in technological scheme disclosed in a kind of Chinese invention patent application of high-performance polyethylene double-wall corrugated pipe, several discontinuous stiffening rib is provided with at the axial trough place of ripple tube layer, the discontinuous stiffening rib of this structure is poor for solving above-mentioned technical problem effect, and its production and processing procedure complexity, cost is higher.
Model utility content
Technical problem to be solved in the utility model is to provide one.
For solving the problem, technical solution adopted in the utility model is:
A kind of steel band reinforced polyethylene spiral ripple pipe; its key technology is: it comprises the bellows body be made up of polyethylene inner layer matrix and outer layer of polyethene and the steel band be spirally coiled on described polyethylene inner layer matrix outer wall; described outer layer of polyethene wraps on described polyethylene inner layer matrix and steel band; combine together in described outer layer of polyethene and polyethylene inner layer matrix joint; the section of described steel band becomes V-type or Ω type; trough place between described steel band is provided with the steel mesh of continuous print coiled coil, and described steel mesh is provided with protective layer.
Further, described protective layer fuses together by the mesh of the steel mesh of outer lining is bonding with the outer layer of polyethene of bellows body.
Further; described steel mesh is laid in described trough place and will is embedded on bellows body after the thawing of the outer layer of polyethene of the bellows body of corresponding part after heating; the outer layer of polyethene compacting that the polyethylene tablet that extruder is extruded is melted by pressure roller and described trough place bonds together, the protective layer described in formation.
Further, described steel mesh is overlapped on the foot of both sides steel band.
The beneficial effect adopting technique scheme to produce is:
By increasing the mode of polyethylene protective layer at traditional steel band reinforced polyethylene spiral ripple pipe outer lining steel mesh; pipeline weak link is strengthened; increase pipeline bulk strength; avoid the pipe polyethylene skin caused because of some special buried condition to be sheared the problem rupturing and cause steel strip reinforced skeleton and polyethylene inner layer matrix to depart from, and add the ring stiffness of pipeline, stability and working life to a certain extent.
Structural enhancing makes steel band reinforced polyethylene spiral ripple pipe have more excellent performance and applicability widely, improves Safety performance and the working life of pipeline.
Outer lining steel mesh steel band reinforced polyethylene spiral ripple pipe can be able to be produced increasing on traditional steel band reinforced polyethylene spiral ripple pipe production line some corollary equipment facilities, and do not need to design production line separately, reforming cost is low.
