Abstract
The utility model relates to a novel pipeline for a coal mine. The novel pipeline for the coal mine comprises a polyethylene pipe body, and a circle of metal wire mesh layer is arranged in the middle of the polyethylene pipe body. According to the novel pipeline for the coal mine, the circle of metal wire mesh layer is arranged in the middle of the polyethylene pipe body, and therefore the entire structural strength of a pipe is enhanced, the pipe can meet the safety requirement of the coal mine; and in addition, the laying of the polyethylene pipe is easier than that of a metal pipe.
Description
[technical field]
The utility model relates to a kind of tubing, is specifically related to a kind of novel colliery and uses pipeline, and it can be applicable to the pipe network systems such as water supply, draining, pressure wind, whitewashing and extraction watt silk under the coal mine.
[background technique]
For guaranteeing the production safety under the coal mine, when coal excavates, must guarantee the ventilation of down-hole, assemble to avoid gas, coal dust.The coal mine method of ventilation of existing technology mainly is that tubing is fed the down-hole, thereby realizes ventilating and firedamp drainage.And the tubing that adopts is essentially metal tube, and the user cost of metal tube is higher, and the laying difficulty is also bigger.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of and have structure improved novel colliery and use pipeline, to overcome said defective of the prior art.
[model utility content]
For addressing the above problem, the purpose of the utility model is to provide a kind of structural strength high, and lays easy novel colliery and use pipeline.For realizing above-mentioned purpose, the technological scheme that the utility model is taked is: pipeline is used in a kind of novel colliery, and it comprises a polyethylene body, in the middle of said polyethylene body, is provided with a circle oven wire mesh blanket.
The novel colliery of the utility model further is set to pipeline: the thickness of said oven wire mesh blanket is 0.2mm.
The novel colliery of the utility model also can be set to pipeline: the cross section of said polyethylene body is rounded.
Compared with prior art; The utlity model has following beneficial effect: the novel colliery of the utility model is enclosed oven wire mesh blanket with pipeline through in the middle of the polyethylene body, being provided with one; Thereby strengthened the overall construction intensity of this tubing, made it meet the safety requirement of coal mine; And this polyvinyl piping materials is easy to lay than metal pipe.
[description of drawings]
Fig. 1 is the sectional view of the novel colliery of the utility model with pipeline.
[embodiment]
See also shown in the Figure of description 1, the utility model is that pipeline is used in a kind of novel colliery, and it comprises a polyethylene body 1, the rounded structure of the cross section of this polyethylene body.
The novel colliery of the utility model is with pipeline greatest improvement part: in the middle of said polyethylene body 1, be provided with a circle oven wire mesh blanket 2, the thickness of this oven wire mesh blanket 2 is 0.2mm.
The novel colliery of the utility model is enclosed oven wire mesh blanket 2 with pipeline through in the middle of polyethylene body 1, being provided with one, thereby has strengthened the overall construction intensity of this tubing greatly, makes it meet the safety requirement of coal mine; And this polyvinyl piping materials is easy to lay than metal pipe.
