Abstract
A kind of solid filling separate material pipe disclosed by the invention, including being located at the three-decker commissioning pipe fed intake in boring, three-decker commissioning pipe and feed intake boring between poured concrete, three-decker commissioning pipe is followed successively by overcoat, intermediate layer and wearing layer inside from outward.Overcoat and intermediate layer are seamless steel pipe, and the outer wall in intermediate layer is close to overcoat inwall, and the two employing is welded to connect；Wearing layer uses high-abrasive material spun casting on the inwall of intermediate layer.The present invention can realize solid filling material and throw in conveying continuously from ground to down-hole, three-decker commissioning pipe structure can guarantee that the longer length of service and relatively low use cost, provides new way for solving colliery and non-coal mine solid filling exploitation attal transportation problem.
Description
Technical field
The present invention relates to a kind of solid filling separate material pipe, especially one and ground solid material is thrown to down-hole, for coal
The tubing of attal conveying in ore deposit and metal mine filling mining.
Background technology
The exploitation of traditional coal and non-coal resource can cause surface collapse, and level of ground water declines, discharge waste pollution environment etc.
A series of problem.The appearance of filling mining method well solves these problems, particularly solid filling and exploits, can not only
Enough control goaf strata movement, the solid waste such as mining area such as spoil, mine tailing, flyash can also be processed simultaneously, it is to avoid this
The destruction that environment is caused by a little solid waste in accumulation on ground surface.In today that solid filling production technique reaches its maturity, the most sharp
By advanced technological means, it is achieved solid material from ground to down-hole from tens of rice to the continuative transport of the upper km discrepancy in elevation, it is ensured that fill
Fill out the continuous controlled supply of material, be the difficult problem needing solution at present badly.
Summary of the invention
Technical problem: it is an object of the invention to for problem present in prior art, it is provided that a kind of simple in construction, safe and efficient,
Service year limit for length, the solid filling separate material pipe that using effect is good.
Technical scheme: the solid filling separate material pipe of the present invention, including being located at the three-decker commissioning pipe fed intake in boring, three
Rotating fields commissioning pipe and feed intake boring between poured concrete, three-decker commissioning pipe is followed successively by overcoat, centre inside from outward
Layer and wearing layer.
Described overcoat and intermediate layer are seamless steel pipe, and overcoat thickness is not less than 14mm, and intermediate layer thickness is not less than
12mm, the outer wall in intermediate layer is close to the inwall of overcoat, and the two welds together.
Described wearing layer uses high chromium nickel molybdenum rare alloy abrasion resistance material spun casting on the inwall of intermediate layer, and thickness is
15mm～65mm.
Beneficial effect: the present invention can realize being delivered to the ground safe and efficient input of solid filling material in solid filling is exploited
Down-hole, is applicable to carry the scope of tens meters of supreme kms of the discrepancy in elevation, and the particularity of commissioning pipe structure may insure that solid filling thing
Material throws in the safe and reliable of transfer passage, the abrasion to input transfer passage of the opposing solid material, extends the use longevity of transfer passage
Life.Present configuration is simple, and strong adaptability has application value widely.
Accompanying drawing explanation
Fig. 1 is solid filling separate material pipe structural representation of the present invention.
Fig. 2 is the sectional view of solid filling separate material pipe of the present invention.
In figure: 1-ground, 2-feeds intake boring, 3-commissioning pipe, 4-overcoat, 5-intermediate layer, 6-wearing layer, 7-concrete.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are further described:
As it is shown in figure 1, the solid filling separate material pipe of the present invention, mainly it is made up of the commissioning pipe 3 of three-decker, three-layered node
The commissioning pipe 3 of structure is installed on and is fed intake in boring 2 by what constructed vertically downward to down-hole in ground 1, the commissioning pipe of three-decker 3 with
Feed intake and poured concrete seven between boring 2, by the concrete poured, the commissioning pipe 3 of three-decker is fixed, formed
Attal is thrown in by ground the passage being delivered to down-hole.
As in figure 2 it is shown, the structure of commissioning pipe 3 is divided into 3 layers, it is followed successively by overcoat 4, intermediate layer 5 and wearing layer 6 inside from outward.
Overcoat 4 and intermediate layer 5 are seamless steel pipe, and overcoat 4 thickness is not less than 14mm, and intermediate layer 5 thickness is not less than 12mm,
The outer wall in intermediate layer is close to overcoat inwall, and the two employing is welded to connect.Wearing layer 6 uses high chromium nickel molybdenum rare alloy wear-resisting material
Material spun casting is on the inwall of intermediate layer 5, and thickness is determined jointly according to the drilling depth that feeds intake, solid filling thruput and character
Fixed, generally 15mm～65mm.
Described it is installed on the three-decker commissioning pipe 3 fed intake in boring 2, it is possible to achieve solid filling material is from ground to down-hole
Continuously, safe efficient transport, its rub proofness is high, and good reliability can obtain the longer length of service in process of production,
Thus reduce the use cost of enterprise.
