Abstract
The utility model discloses a support type special pipe for gas drainage. Reinforcing ribs are arranged in a pipe body; and between the reinforcing ribs and the pipe body, there is provided a hollow structure. During a gas drainage process, with the reinforcing rib arranged in the pipe body, once a coal presses the pipe, compression resistance of the pipe stock is greatly enhanced; and fulcrums exist upon collapse of a drill hole, so a gas collecting hole cannot be totally blocked and normal gas drainage of the drill hole is free of effect.
Description
Technical field
The utility model belongs to colliery technical field, relates to a kind of tubing, specifically, relates to a kind of support type gas drainage under suction special pipe.
Background technology
In the process of gas discharge in mine; because of geology, compose the impact of depositing situation and digging dynamic pressure, firedamp taking-out discharging drilling often there will be the phenomenons such as collapse hole, plug-hole, causes releasing pipe to be crushed and stops up gas collection hole; this will affect the effect of gas drainage under suction greatly, causes the waste of artificial and material.For the phenomenon of avoiding collapse hole to flatten releasing pipe occurs, should improve the compressive strength of pipe, can increase pipe wall thickness, but must waste thus raw material and increase cost.In use, once there is collapse hole, due to the effect of inner support, the resistance to compression effect of pipe strengthens support type gas drainage under suction shape tube greatly, can reduce the phenomenon that collapse hole is flattened releasing pipe; Under the effect of outer support, can guarantee that gas collection hole is not blocked completely, guarantee carrying out smoothly of extraction simultaneously.
Utility model content
In order to overcome defect of the prior art, the utility model provides the support type gas drainage under suction special pipe that a kind of compressive strength is high.
Its technical scheme is as follows:
A gas drainage under suction special pipe, is provided with reinforcing rib in body inside, is hollow state between described reinforcing rib and body.
Further preferably, in body outside, be provided with outstanding fulcrum.
Further preferably, on the body near outstanding fulcrum place, be provided with gas collection hole.
Further preferably, in body outside, be provided with gas collection hole, described gas collection hole is arranged evenly by common three presbyopia.
Further preferably, described reinforcing rib is 3.
Further preferably, the angle between described adjacent two reinforcing ribs is 120 °.
Compared with prior art, the beneficial effects of the utility model:
In the technical solution of the utility model, on the basis of common tubing, inner every 120 ° of tubing, increased reinforcing rib, corresponding fulcrum also can be given prominence to according to demand in tubing outside.In gas drainage under suction process, once coal body is pressed, under the effect of inner reinforcing rib, the resistance to compression effect of tubing strengthens greatly, and the in the situation that of boring landslide, the existence of outstanding fulcrum, is unlikely to gas collection hole to block completely, does not affect the normal gas drainage under suction of boring.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model support type gas drainage under suction special pipe.
Fig. 2 is the design sketch of the utility model support type gas drainage under suction special pipe.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in more detail.
With reference to Fig. 1, a kind of support type gas drainage under suction special pipe, is provided with reinforcing rib 2 in body 1 inside, between described reinforcing rib 2 and body 1, is hollow state.In body 1 outside, be provided with outstanding fulcrum 3.In the situation that being provided with outstanding fulcrum 3, on the body 1 near outstanding fulcrum 3 places, be provided with gas collection hole 4.Outside not being provided with in the situation of giving prominence to fulcrum 3, is provided with gas collection hole 4 in body 1 outside, and described gas collection hole 4 is arranged evenly by common three presbyopia.Described reinforcing rib 2 is 3.Angle between described adjacent two reinforcing ribs 2 is 120 °.
The above; it is only the preferably specific embodiment of the utility model; protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses, the simple change of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen in protection domain of the present utility model.
