Abstract

The utility model provides a plastic row-shaped twisting pipe section material which is composed of a plastic base (1), a row-shaped bridge connecting arc (2) on the plastic base (1), and a (3) and a (4) respectively positioned at both sides of the section material via extrusion molding winding. The section material can be used for winding pipelines with high speed, material saving, energy source saving and low cost, and the utility model has the advantages of high extrusion strength and favorable vibration damping performance, sealing performance and leakage resisting performance. The utility model is mainly used for water supply and draining, drain pipes, farm irrigation, casing tubes for the ventilation, electric power and telecommunication of mines and buildings, oil pipes and gas pipes.

Description

Plastics row type enwound tube section bar

One, technical field

The utility model relates to a kind of plastic conveying and plastic pipeline profile, is specially adapted to twine the plastic material of large diameter pipeline.

Two, technical background

Traditional conveyance conduit, especially for the giving of municipal works, draining, buried pipeline, the especially large diameter pipeline in fields such as blowdown, flood discharge, agricultural irrigation, industrial and mineral ventilation mainly adopt pipe of cement, and cast iron pipe is laid.Because the production cost of heavy caliber pipe of cement and cast iron pipe and cost of transportation height, big, the installation inconvenience of weight; The easy fouling of its wall, mossy cause flow resistance big, even block; And cast iron pipe easily gets rusty, and pipe of cement uses the generation seepage to cause secondary pollution for a long time.Nation-building portion issue is promoted the novel plastic building materials about eliminating notice time limit forbidding pipe of cement and the cast iron pipe that falls behind technology and product, therefore, uses plastic conduit to become current development trend.China nearly all has been in small-bore pipeline, solid wall pipe road since the research and development plastic conduit, and Patent Office of the People's Republic of China's patent granted number is that 93205430.7 patented product promptly is an example that is wound in pipeline with profiled sheeting.Its architectural feature is that every spiral reinforcing rod in the helix tube outside is a hollow shape, and the side of every adjacent two spiral reinforcing rods equates that two ends adopt the rectangle tongue-and-groove to connect.Though this plastics winding screw pipe is gained in strength because of having used reinforcement, its weak point is the groove insufficient strength of tube wall, is easily exposed and leaks by sharp device, and because section bar twines relatively, when being curled into helix tube, it is very long to twine seam, is difficult to ensure the quality of products and may produces pipe leakage.

Three, summary of the invention

The purpose of this utility model is to provide a kind of winding process that is easy to control, and the tubing better anti-leakage property of shaping has higher intensity and speed of wrap fast, the plastics row type enwound tube section bar of energy savings cost.The purpose of this utility model is achieved through the following technical solutions: is wound in the section bar of plastics row type winding pipe, forms by continuous row's type bridge arc, and the evenly outside camber of bridge arc, the two ends of section bar are the shape of rule.

The utility model beneficial effect compared with prior art is: owing to be to be connected as a single entity by continuous bridge arc, this bridge arc surface makes whole plastics row type winding pipe in fact form double-walled row type pipe, the intensity of pipeline and pressure degree, shock strength have not only been strengthened, and the sharp device of outer surface resisted effect, not therefore promptly this outer surface is punctured, and tube wall can be and seepage yet.Owing to adopted extrusion molding to be wound in pipe, winding seam and section bar are fused into one, there is not seam, the sealing anti-seepage effect of winding pipe is greatly strengthened, because of adopting extrusion molding to twine, make it sealing and be easy to control, speed of production is accelerated, improve airtight quality, reduced workload, reduced cost.

Five, the specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing, but they are not to qualification of the present utility model.

Be that continuous bridge arc is evenly formed on the basal part 1 of section bar, outer surface is even, becomes the bridge camber to evagination, and the both sides of section bar are surperficial uniformly.

Embodiment makes the banded section bar of cross section row's type as shown in Figure 1 with plastic material, and with the bridge arc ∩ type on the section bar basal part 1, the outer surface of boss evenly becomes the bridge camber to evagination.The two ends of basal part 1 are respectively to have a long-pending bridge arc of 4/5ths cylindrical surfaces, and 3 and 4 twine through extrusion molding and to be connected as a single entity, and form pipeline.
