Description
Technical field
The utility model relates to cylinder concrete pipe technical field, is specifically related to a kind of lined cylinder concrete pipe carrying direct drinking.
Background technique
Direct drinking refers to that user terminal directly exports the potable water meeting NBS.Direct drinking water project is domestic not universal at present, and be detected in the location pilot in small part city, associated conduit, the auxiliary facility in most domestic city are not also transformed completely, can not reach the standard that the water quality after registering one's residence also reaches direct drinking.As the important link in direct drinking water project, the direct drinking after purification carries common practice both domestic and external to be all adopt stainless steel pipeline.
The outstanding anti-corrosion capacity of stainless steel pipeline, make stainless steel pipeline can the water quality safety of effective guarantee direct drinking, but Stainless Steel Tube relative to common steel tube and concrete pipe cost higher, if adopt common steel tube in direct drinking water project, steel pipe inner wall contacts the water quality safety that the corrosion products entail dangers to produced carries water with water, and adopt its effect of concrete pipe poorer, because the concrete layer of concrete pipe internal layer, due to water long-time stop in the duct with wash away, some materials inside concrete layer can be made to enter in water, have influence on water quality safety.
Summary of the invention
The technological deficiency of the requirement of direct drinking water project can not be reached for solving cylinder concrete pipe in prior art, the utility model designs a kind of lined cylinder concrete pipe carrying direct drinking, achieve cost-saving while, the object of water quality safety can also be ensured, avoid employing common steel tube, steel pipe inner wall contacts the water quality safety that the corrosion products entail dangers to produced carries water with water, adopts concrete pipe, make some materials inside concrete layer enter in water, have influence on the problem of water quality safety.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of lined cylinder concrete pipe carrying direct drinking, comprise steel cylinder, steel cylinder two ends are welded with socket steel ring and bellmouth steel loop respectively, and steel cylinder and the equal hoop of bellmouth steel loop outer wall are wound with reinforcement wire, the reinforcement wire outer wrapping cement mortar protective course of steel cylinder and bellmouth steel loop; The equal fill concrete layer in inside of the weld part of socket steel ring, steel cylinder and steel cylinder and bellmouth steel loop, the embedded stainless-steel pipe of concrete layer.Inner liner stainless steel pipe in traditional concrete pipe; the cost being used alone Stainless Steel Tube can be reduced on the one hand; lose from the angle of multi-layer anticorrosion on the other hand; because the concrete pipe outside Stainless Steel Tube is cylinder concrete pipe; there is concrete, steel cylinder, steel wire, cement mortar protective course multi-layer anticorrosion compression-resistant structure feature; if the cylinder concrete pipe of inner liner stainless steel pipe is applied to direct drinking water project; have applied widely undoubtedly, the economic life be long, anti-seismic performance good, easy for installation, ensure the direct drinking advantage such as safely.
Further, the outer wall of bellmouth steel loop and stainless-steel pipe is all connected with the fin extended vertically.What contact with the outer wall of bellmouth steel loop and stainless-steel pipe is cement mortar protective course and concrete layer respectively; at all affixed fin extended vertically of outer wall of bellmouth steel loop and stainless-steel pipe; can vertical die build shaping after, make bellmouth steel loop and cement mortar protective course, Stainless Steel Tube and concrete layer have better fixing and combination.Extend the working life of cylinder concrete pipe greatly.
Preferably, bellmouth steel loop and fin and stainless-steel pipe and fin are integral type structure.When producing bellmouth steel loop and the stainless-steel pipe of band fin, can adopt the production technology of molding and forming, technique is simple, and cost is lower, and substantially increases the band bellmouth steel loop of fin and the steadiness of stainless-steel pipe.
Preferably, collar flange is all welded in the two ends of stainless-steel pipe, and the peripheral portion of collar flange fits tightly with the inwall of socket steel ring and bellmouth steel loop respectively.Also namely the two ends of stainless-steel pipe cover concrete layer two ends respectively, make external substance be difficult to directly contact concrete layer, the anti-corrosion capacity of whole cylinder concrete pipe is improved greatly.
The beneficial effects of the utility model are: 1, the lined cylinder concrete pipe of this conveying direct drinking can be applied to the direct drinking water project in water delivery engineering, effectively can suppress the stripping of material in concrete layer, for water delivery increases safely important barrier together, application is convenient; 2, the lined cylinder concrete pipe overall structure of this conveying direct drinking is very simple, design science is reasonable, there is good durability, impermeability, cracking resistance, corrosion resistance, and manufacturing process is simple, is the lined cylinder concrete pipe of the conveying direct drinking that a kind of novelty is higher.
