Description

A kind of communication pipe of communication system

Technical field

The present invention relates to the communications field, particularly a kind of communication pipe.

Background technology

Expressway communication pipeline is a part for expressway construction, and its purposes is mainly used for laying highway machine Electric system optical cable.Movement, UNICOM, telecom operators can also be supplied, and private network user Deng Ge enterprises and institutions rent, and have huge Big social benefit, also creates economic benefit for highway itself simultaneously.

Communication pipe mainly includes main line communication pipe and lower ring road enters the communication pipe in area of charge station.Current height Fast highway typically adopts 40/33 silicone pipes as communication pipe, and main line lays 12-24 root, and lower ring road lays 6-8 root.Totally come Say take up room big, be unfavorable for constructing, and relatively costly.On the other hand, cost of material follows oil price fluctuation, and manufacturer is confused Confusingly adopt regrown material with reduces cost, cause domestic silicone pipes product quality at present generally inferior, to later stage cabling construction with And the permanent operation security of communications optical cable brings hidden trouble；And the structure using " pipe one cable ", regardless of Cable Core Number and Cable footpath thickness, conduit resource utilization rate is not high, wastes very big.

Content of the invention

Goal of the invention：For the deficiencies in the prior art, this utility model provides a kind of communication pipe of communication system, is used for The communication pipe of silicone pipes formula solving to use on existing highway has that volume is big, high cost, quality are low, pipeline wastes Many technical problems such as serious.

Technical scheme：

A kind of communication pipe of communication system, forms bundle pipes by micro-pipe and restrictive coating, and described micro-pipe has one or many Individual, the external diameter of described micro-pipe is less than or equal to 16mm, and all micro-pipes are according to setting structure arrangement form bundle pipes inner core, described shield Jacket layer is closely coated on the outside of inner core；Described micro-pipe is separate each other；No adhesion between described inner core and restrictive coating； The material of described micro-pipe and bundle pipes is high density polyethylene (HDPE).

Further, in this utility model, the material rate of described micro-pipe is more than PE80 level.Common silicone pipes are general Produced using PE63 level HDPE, there is more preferable weather resistance and mechanical performance.

Further, in this utility model, described micro-pipe inwall is provided with lubricating layer.Because micro-pipe is that air-blown installation is micro- The direct carrier of cable, so setting lubricating layer is conducive to the micro- cable of follow-up air-blown installation.

Further, in this utility model, described micro-pipe inwall is provided with the guiding gutter along micro-pipe axial direction.After being similarly The micro- cable of continuous air-blown installation provides facility.

Beneficial effect：

This utility model provides a kind of communication pipe of highway communication system, is different from traditional employing 40/33 silicon Core pipe is as communication pipe；Form boundling tubular construction using micro-pipe outer cladding restrictive coating, the silicone pipes that can replace routine completely are made For the communication pipe of highway, have the advantage that compared with traditional silicone pipes：

Bundle pipes have take up room little the features such as make that pipeline is safer, integrated cost is low, be suitable for air-blowing and construct, very suitable Close the use scene of highway；

In the case that pore resource quantity is constant, the number of tubes that need to lay reduces at double, and space occupancy rate reduces, and applies Work quantities few more than 40%, holistic cost reduces 20%-30%, if promote the use of thering is good economic benefit and society's effect Benefit.

Brief description

Fig. 1 is structural representation of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model is done and further explain.

As shown in figure 1, this structure is made up of internal micro-pipe 2 and outside restrictive coating 1.

Micro-pipe：It is the most basic component units of bundle pipes, be also the direct carrier of the micro- cable of air-blown installation.Micro-pipe is with high-grade High density polyethylene (HDPE) (HDPE) be raw materials for production, general nominal outside diameter be not more than 16mm plastic pipe it can be understood as ratio External diameter/internal diameter is the more small-bore silicone pipes of 32mm/26mm, 25mm/20mm.Micro-pipe is circular, and its pipe material inner wall equally has There is the permanent solid silicon core lubricating layer of synchronous production extruding, part micro-pipe inwall also carries longitudinal water conservancy diversion rib slot structure, further Reduce inner-walls of duct and the frictional force of micro- cable contact surface, be beneficial to the micro- cable of follow-up air-blown installation.Due to the construction featuress of itself, Micro-pipe cannot add reworked material when producing, or draws thin pipe wall, otherwise cannot molding.Ensure that and completely newly must expect using 100% Produce, product quality is secure, more than 50 years quality assurance, completely eliminates the hidden danger of quality of silicone pipes from manufacturing process.

Bundle pipes：By a hole or perforated micro-pipe according to certain frame mode permutation and combination, external sheath is high-grade highly dense Degree polyethylene (HDPE) restrictive coating, that is, constitute bundle pipes, received more pore numbers in limited space content.Protect outside bundle pipes Jacket layer and internal micro-pipe closely coat, and adhesion, form closely tight overall structure.Between the micro-pipe pore in bundle pipes Independently of one another, external sheath layer peels off posterior microtubule can relative displacement, be easy to selecting and continuing of micro-pipe.Restrictive coating gives inside Microtubule fasolculuss extra mechanical protection is provided, also ensure that bundle pipes disclosure satisfy that direct-burried requirement.

Raw material

Produce micro-pipe and the major ingredient of restrictive coating should not allowed using the high density polyethylene (HDPE) extrusion molding resin meeting national standard Adulterate any kind of returns in the feed.Typically there is following typical technology parameter：

Melt index (MI)：0.1～1.4g/10min (190 DEG C, 2.16KG)

Relative density： ≥0.940g/cm3

Tensile yield strength： ≥21MPa

Fracture elongation：>=350%

Resisting environmental stress and cracking F50： ≥96h

Color

The restrictive coating of bundle pipes and micro-pipe can adopt colouring discrimination.Its color be meet the indigo plant that GB6995.2-1986 specifies, Orange, green, brown, grey, white, red, black, yellow, purple, pink or dark green.In the case of not affecting identification, it is possible to use colo(u)r streak is adding To identify.The color of colo(u)r streak selects from table 1 below.

Table 1

Physical dimension

Table 2 gives micro-pipe and the physical dimension of bundle pipes requires.

Table 2

Mechanical performance

The performance requirement of the restrictive coating of bundle pipes is as shown in table 3.

Table 3

In bundle pipes, external diameter/internal diameter includes stretching, fracture elongation, flat, ring for the mechanical performance of 12mm/9mm micro-pipe Rigidity, shock resistance, longitudinal welds, air-blowing performance etc., meet the requirement shown in table 4.

Table 4

General using the bundle pipes with the micro-pipe that 4 hole external diameters/internal diameter is 12mm/9mm or have 7 hole external diameters/internal diameter The bundle pipes of the micro-pipe for 12mm/9mm can meet the demand of current expressway communication pipeline engineering.The allusion quotation of 7 hole bundle pipes Shown in the Fig. 1 of type section.

The above is only preferred implementation of the present utility model it is noted that common skill for the art For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and Retouching also should be regarded as protection domain of the present utility model.
