Description
Technical field
The utility model is related to a kind of tubing, specifically refers to a kind of MPP no-dig techniques cable protection pipe.
Background technology
At present, MPP pipes are with its good insulating properties, crushing resistance, moisture-proof, it is easy to wear the advantages of payout, easy construction
It is used as the main tubing of cable protection pipe.The operating temperature of MPP pipes is general between -5 DEG C~70 DEG C, because tubing is generally laid
In underground, difference variation is larger throughout the year, in the case that especially temperature is relatively low in the winter time, pipe performance reduction, is easily damaged,
Inside cable can not be protected very well, and service life is had a greatly reduced quality.
Utility model content
The purpose of this utility model is to provide for a kind of MPP no-dig techniques cable protection pipe, the MPP no-dig technique cable protections
Firmly, easy construction can work, service life is long, and cost is low tubular construction at low ambient temperatures for a long time.
In order to achieve the above object, the utility model provides following technical scheme：A kind of MPP no-dig techniques cable protection
Pipe, including inner tube, the outside of above-mentioned inner tube is provided with outer tube, is provided with hollow layer between said inner tube and outer tube, said inner tube it is interior
Wall is smooth, and outer wall is provided with continuous wavy projection, and the inner and outer wall of the outer tube is smooth, the interior outside of the outer tube
Mineral wool layer is equipped with, the two ends of said inner tube inwall are provided with depression ring.
It is further preferred that being provided with some heat emission holes being connected between said inner tube and hollow layer.
It is further preferred that the depression ring is provided with cushion close to the side of inner tube port.
It is further preferred that said inner tube and outer tube are MPP material layers.
The beneficial effects of the utility model：The MPP no-dig technique cable protection pipe sound constructions, easy construction can exist for a long time
Worked under low temperature environment, service life is long, cost is low.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the MMP no-dig techniques cable protection pipe.
Marginal data：1st, inner tube；2nd, outer tube；3rd, it is raised；4th, mineral wool layer；5th, be recessed ring；6th, hollow layer；7th, heat emission hole；
8th, cushion.
Embodiment
We do further with reference to accompanying drawing to a kind of MPP no-dig techniques cable protection pipe described in the utility model below
It is bright.
As shown in fig. 1, outside a kind of MPP no-dig techniques cable protection pipe of the present embodiment, including inner tube 1, above-mentioned inner tube 1
Side is provided with outer tube 2, and hollow layer 6 is provided between said inner tube 1 and outer tube 2, and the inwall of said inner tube 1 is smooth, and outer wall is provided with continuous
Wavy raised 3, the inner and outer wall of the outer tube 2 is smooth, and the interior outside of the outer tube 2 is equipped with mineral wool layer 4,
The two ends of the inwall of said inner tube 1 are provided with depression ring 5.Some heat emission holes 7 being connected are provided between said inner tube 1 and hollow layer 6.
The depression ring 5 is provided with cushion 8 close to the side of the port of inner tube 1.Said inner tube 1 and outer tube 2 are MPP material layers.Pass through glass
The effectively isolation inner tube 1 and external environment condition of glass cotton layer 4, it is ensured that the internal temperature of inner tube 1 will not because external environment condition is too low and it is quick under
Drop, while inside cable work produces heat, diffuses to hollow layer 6, so that the internal temperature of inner tube 1 is all the time by heat emission hole 7
It is maintained at proper range.The ring 5 that is recessed can be conducive to construction in order to the dragging of body.
Protection domain of the present utility model is not limited to above example and its conversion.Those skilled in that art are with this implementation
The conventional modification and replacement carried out based on the content of example, belongs to protection category of the present utility model.
