Abstract

The utility model relates to a transfer pipeline that takes bamboo chips, wood chips and laminated fiber plates as interlining materials, which consists of an inner layer and an outer layer that are formed by resin as well as an interlining that is closely combined by the inner layer and outer layer, wherein the interlining is a skeleton that is crossly weaved by a vertical rib formed by one of the bamboo, the wood chips and the cane and a transverse rib formed by one of the bamboo, the wood chips and the cane; and the periphery of the skeleton is intertwined by a spiral rib formed by one of the glass fiber, bamboo chips or cane. The utility model is suitable for transferring various liquid and in particular suitable for urban water supply and drainage and rural irrigation.

Description

A kind of multiple tube

Technical field

The utility model relates to a kind of pipeline of carrying liquid, gas and fluid-mixing, and especially relating to a kind of is main material with natural plants such as bamboo chip, wood chip, rattans, is aided with the pipeline that glass fibre and resin are formed.

Background technique

Common conveyance conduit has steel pipe, plastic tube, Glass Steel Tube etc. several at present, all has certain shortcoming.Steel pipe is perishable, working life is short, anti-corrosion measure is complicated, and using scope has bigger narrow limitation, and because of rough inner surface, fluid resistance is bigger after the corrosion, and is easy to generate the seepage phenomenon; Though and glass fibre reinforced plastics and plastic pipe have solved the corrosion-resistant problem, its price is too high, and the user is difficult to accept.

Patent Office of the People's Republic of China discloses a kind of " interlayer fiber reinforced plastic delivery pipe " with notification number CN2035034U, it is to be made of internal layer, interlayer, outer institute, wherein, its interlayer adopts is any one material in reinforced concrete, foamed cement, foamed gypsum, slush, macromolecule resin mortar, foamed plastics, wooden unit, the honeycomb, inside and outside layer adopts glass fibre, carbon fiber, organic fiber insulating varnish and forms, its shortcoming is that the tension, bending resistance of pipeline, antitorque, shearing resistance, inside and outside compressive strength are not enough, and cost is higher.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of prior art and a kind of corrosion resistant, long service life, physical and mechanical property is good and cost is low pipeline are provided.

For achieving the above object, the utility model adopts following design proposal:

A kind of multiple tube, the internal layer that forms by resin and outer, formed with internal layer and outer interlayer of combining closely, wherein interlayer is to form skeleton by vertical muscle and horizontal bar weaving, and constitutes at skeleton periphery winding screw muscle.

Wherein, the material of vertical muscle and horizontal bar can be selected any one in bamboo chip, wood chip or the rattan for use, and the material of vertical muscle and horizontal bar use can be identical, also can be different;

In addition, have the better physical mechanical property in order to guarantee pipeline, the material that uses in the vertical muscle is preferably wide, uniform thickness; Equally, the material that uses in the horizontal bar preferably also is wide, uniform thickness;

The material of spiral bar is any one in glass fibre, bamboo chip or the rattan, but preferably uses glass fibre, and the thickness that glass fibre twines is identical, and is if use is bamboo chip or rattan, preferably wide, uniform thickness.

The utility model has the advantages that: one, corrosion resistant, long service life.The internal layer that is formed by resin and outer bamboo chip, wood chip or rattan are sealed has been isolated contacting of bamboo chip, wood chip or rattan and extraneous medium fully, makes them avoid corrosion and wear out, and has guaranteed the use reliably and with long-term of pipeline; Two, this pipeline is after the solidified forming process treating, and indexs such as its tension, bending resistance, antitorque, shearing resistance, inside and outside compressive strength are very desirable, and physical and mechanical property is fine, has also stopped the seepage of pipeline simultaneously; Three, because resources such as bamboo and wood sheet and rattan are very abundant, and reproducibility is strong again, and is cheap, so the low cost of manufacture of this pipeline, has the stronger market competitiveness.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment 1: a kind of multiple tube, the internal layer 1 that forms by resin and outer 3, formed with internal layer 1 and outer 3 interlayers of combining closely 2, wherein interlayer 2 is that horizontal bar 5 weavings that the bamboo chip of the vertical muscle 4 that forms of the wood chip by contour uniform thickness and contour uniform thickness forms form skeleton, and twine the spiral bar 6 that forms by glass fibre in this skeleton periphery and constitute, the thickness of glass fibre winding is identical.Internal layer of the present utility model 1 adopts resin cast to form, and outer 3 after interlayer 2 forms, with resin impregnation on interlayer 2 and solidified forming, thereby interlayer 2 is encapsulated in it.

Embodiment 2: adopt structure and technology among the embodiment 1, change horizontal bar 5 wood chip of contour uniform thickness into, the bamboo chip that spiral bar 6 is changed into contour uniform thickness gets final product.

The utility model is applicable to the conveying of various liquid, is particularly useful for that the city is given, draining and rural irrigation water delivery.
