Abstract
The present invention relates to one and effectively can improve heavy caliber bellows intensity, heavy caliber bellows weight can be alleviated again, a kind of hollow corrugated pipe and the making method of heavy caliber bellows material can be reduced again simultaneously, it comprises bellows, and described bellows is formed by stacking by the plastic tube spiral with hollow tube core and melting sealed connection between the tube wall of the plastic tube of spiral superposition.Advantage: one is the precedent having started single wall hollow corrugated pipe; Two is the intensity both having improved heavy caliber bellows, alleviates again heavy caliber bellows weight, reduces again the consumption of heavy caliber bellows material simultaneously.
Description
Technical field
The present invention relates to one and effectively can improve heavy caliber bellows intensity, heavy caliber bellows weight can be alleviated again, a kind of hollow corrugated pipe and the making method of heavy caliber bellows material can be reduced again simultaneously, belong to bellows and manufacture field.
Background technique
CN201731192U, title " large-caliber double-wall corrugated water pipe ", its tube wall is made up of inside and outside two-layer, and its inner tubal wall is smooth, and outer tube wall is trapezoidal corrugated, is provided with stirrup in the cavity between inside and outside wall, and connects as one at outer wall trapezoidal bottom groove and inwall.Stirrup is provided with in cavity between this large-caliber double-wall corrugated water pipe inside and outside wall, improve the intensity of water pipe, have compared with the heavy-calibre steel-plastic drain generally used in prior art that overall weight is light, cost is low, the feature that easy to install and cost of production is low.Its deficiency: because the tube wall of bellows is made up of inner and outer wall, the compressive strength of its inwall is strengthened by outer wall, and not only weight is large, and raw materials consumption is large, and compressive strength is uneven.
Summary of the invention
Purpose of design: avoid the deficiency in background technique, design one can improve heavy caliber bellows intensity effectively, can alleviate again heavy caliber bellows weight, can reduce again a kind of hollow corrugated pipe and the making method of heavy caliber bellows material simultaneously.
Design proposal: in order to realize above-mentioned purpose of design.The present invention is in structural design, and the design that bellows is formed by stacking by the plastic tube spiral with hollow tube core is technical characteristics of the present invention.The object done like this is: it by existing double-wall corrugated water pipe by double-deck Split type structure, change overall structure into, both escaped the inwall eliminated in background technique, incorporate again the outer wall in background technique, make the corrugated pipe wall after integration both have the function of inwall, there is again the function of outer wall.Therefore, not only bearing strength is high, low cost of manufacture, and lightweight, considerably reduce raw-material consumption.
Technological scheme 1: a kind of hollow corrugated pipe, it comprises bellows, and described bellows is formed by stacking by the plastic tube spiral with hollow tube core and melting sealed connection between the tube wall of the plastic tube of spiral superposition.
Technological scheme 2: a kind of making method of hollow corrugated pipe, the heavy caliber polyolefin that hollow tube is manufactured by claimant be wound around increase pipe production line after composite plastic layer directly on bellow forming and with hollow tube core plastic tube wall between adhere form hollow corrugated pipe.
The present invention is compared with background technique, and one is the precedent having started single wall hollow corrugated pipe; Two is the intensity both having improved heavy caliber bellows, alleviates again heavy caliber bellows weight, reduces again the consumption of heavy caliber bellows material simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of hollow corrugated pipe.
Fig. 2 is the sectional structure schematic diagram of hollow corrugated pipe.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of hollow corrugated pipe, it comprises bellows 1, and described bellows 1 is formed by stacking by plastic tube 3 spiral with hollow tube core 2 and melting sealed connection between the tube wall of the plastic tube 3 of spiral superposition.Described hollow tube core 2 is metal die or nonmetal tube core., its making method system prior art, is not described herein at this.
Embodiment 2: on the basis of embodiment 1, a making method for hollow corrugated pipe, the heavy caliber polyolefin that hollow tube 2 is manufactured by claimant be wound around increase pipe production line after composite plastic layer directly on bellow forming and with hollow tube core 2 plastic tube 3 wall between adhere form hollow corrugated pipe.
It is to be understood that: although above-mentioned, mentality of designing of the present invention is contrasted detailed text description; but these text descriptions; just the simple text of mentality of designing of the present invention is described; instead of the restriction to mentality of designing of the present invention; any combination not exceeding mentality of designing of the present invention; increase and amendment, all fall within the scope of protection of the present invention.
Claims (2)
1. a hollow corrugated pipe, it comprises bellows (1), it is characterized in that: described bellows (1) is formed by stacking by plastic tube (3) spiral with hollow tube core (2) and melting sealed connection between the tube wall of the plastic tube (3) of spiral superposition; Its making method, the heavy caliber polyolefin that hollow tube core (2) is manufactured by claimant be wound around increase pipe production line after composite plastic layer directly on bellow forming and with hollow tube core (2) plastic tube (3) wall between adhere form hollow corrugated pipe, make corrugated pipe wall both have the function of inwall, there is again the function of outer wall.
2. hollow corrugated pipe according to claim 1, is characterized in that: described hollow tube core (2) is metal die or nonmetal tube core.
