Description

One kind enhancing carat pipe
Technical field
The utility model is related to a kind of large diameter pipeline, and in particular to one kind enhancing carat pipe.
Background technology
Carat pipe, also known as be HDPE winding structure pipes, it is with high-density polyethylene resin as main raw material(s), using heat State winding shaping process, Auxiliary support pipe is done with PP or PE single-wall corrugated pipes, the high density produced using hot winding shaping process Poly ethylene large caliber winding reinforcing pipe.Carat pipe is a kind of environmental protection and safety type product, with lightweight, bearing capacity is strong, interface Quality is high, long lifespan, corrosion-resistant, ring stiffness high, easy construction the advantages of, be widely used in urban water supply, draining, remote conveying The engineering such as water and irrigation and water conservancy irrigation, but carat pipe also has the disadvantage that:(1)The rigidity of PE materials is too low, in order to reach The standard of epipodium stiffness pipe, then need to increase the consumption of PE materials, so as to can cause the product cost to reduce;(2)Work as production When heavy caliber, high ring rigidity carat tubing, even increasing the requirement that PE materials are also unable to reach manufacture high ring rigidity product, because This needs to produce the tubing of sandwich construction, and the method reduce further the cost performance of product, and considerably reduces production effect Rate.
In the prior art, the Enhancement Method of most of carats of pipes is by the way of single-wall corrugated pipe is strengthened, such as:In single wall The inside of bellows adds the reinforcement of different structure unlike material;Single-wall corrugated pipe is filled into solid;In single wall ripple The tube wall of pipe adds steel loop enhancing etc., but winding difficulty using the enhanced single-wall corrugated pipe of these methods is increased, meanwhile, The cost of manufacture carat pipe is also increased, its processing technology is also increasingly complex.In addition, these methods are merely enhanced and are wound with list The part of wall bellows, the rigidity for not winding the part of single-wall corrugated pipe is still weaker.
The content of the invention
To overcome existing technological deficiency, the utility model provides a kind of carat that rigid material is enclosed with internal layer Pipe, can be substantially improved the ring stiffness of tubing, while not influenceing the other performance of product.
To realize the purpose of this utility model, it is achieved using following technical scheme:
