As in figure 2 it is shown, described heat supplying pipeline 12 includes main air supply pipe 121, arm 122, radiating tube 123
With drain pipe 124；Often at least provided with an arm 122, each arm in the passage below row's hydraulic support 10
122 connect with main air supply pipe 121；Described radiating tube 123 is arranged multiple along arm 122 length direction interval,
And each radiating tube 123 is sequentially connected in series by this arm 122；Every radiating tube 123 the most respectively with drain pipe 124
Connection.
The two ends of the passage that each row's hydraulic support 10 is formed are provided with bar-mat reinforcement 14, and this bar-mat reinforcement 14 is coated over
Inside described canvas 11.
The edges and corners of each hydraulic support 10 are coated with two-way stretching plastic net, and this two-way stretching plastic net is capped
Inside described canvas 11.
1st drains in m-1 row's hydraulic support 10, head and the tail overlap joint position between adjacent two row's hydraulic supports 10
Put the pit of place's formation overlaid with supporting plate 13.
Described canvas 11 is provided with two-layer, and wherein internal layer uses insulation canvas, and outer layer uses airtight Tarpauling.
The steel pipe of diameter 108mm selected by described main air supply pipe 121；Arm 122 selects the steel of diameter 80mm
Pipe；Diameter 159mm steel pipe selected by radiating tube 123, and drain pipe 124 selects 50mm coating steel pipe.
The surrounding ground of hydraulic support array is provided with the dash platform 15 of concreting, described dash platform
15 are coated over inside canvas 11.
Described arm 122, radiating tube 123 and drain pipe 124 use wire rope hanging in hydraulic support 10

Outside the dash platform 15 of hydraulic support array surrounding, heap has sandbag 16, described sandbag 16 to be pressed in canvas 11
Upper for Radix Saposhnikoviae.
Below in conjunction with specific embodiment, the form of construction work of the present invention is stated:
One, preparation of construction
1, Work tool: 380V electric welding machine two, pipe cutting machine one, angle grinding machine one, manpower flat car one
Frame, φ 50 steel pipe jenny scaffold four frame, double ladder two frame, each specification adjustable wrench and specification quincuncial plate etc..
2, material prepares: φ 159 seamless steel pipe 50m, φ 108 steel pipe 120m, φ 80 steel pipe 260m,
φ 50 coating steel pipe 320m, canvas and each specification pipe fitting, auxiliary material.
Two, arrangement and method for construction
(1) arrangement of hydraulic support
Divide three row's arrangements (being defined as: 1 row, 2 rows, row 3) by hydraulic support 10 according to North and South direction, often arrange
40 framves.2nd, 3 row's back timber ends are pressed in the 2nd discharge opeing pressure to end, the 1st row's hydraulic support 10 front-axle beam
On frame 10 caving shield.
Making three row's hydraulic supports 10 that a ∩ shape is integrally formed from outside, North and South direction girth is minimum, reduces sail
Cloth 11 consumption.Canvas 11 after simultaneously covering tightly sticks together, by wind with hydraulic support 10 outline
Rear shake is little, reduces impaired with the friction of hydraulic support 10.And at the 1st row and the 2nd row's hydraulic support 10
At the cavity that top overlap joint is formed, every frame North and South direction puts two pieces of 3000*220*30mm (long * width * is thick) supporting plate
13.Do so is that to allow hydraulic support 10 top be a plane, prevents cavity, hydraulic support in winter 10 top
Accumulated snow, penetrates into inside hydraulic support after thawing, causes the corrosion to hydraulic support parts.
(2) heating pipeline arrangement
Main air supply pipe 121 uses recovery φ 108 under mine to manage；Arm 122 uses φ 80 steel pipe；Dissipate
Heat pipe 123 uses ore deposit φ 159 waste material to process about 1.2 meters, and both sides 0.6 steel plate blocks, every 3
Frame arranges one；Drain pipe 124 uses φ 50 coating steel pipe pipe fitting to connect, often below row's hydraulic support 10
One road arm 122, totally 3 tunnel is installed.
All pipelines and processing weldment workshop welding processing, Assembling；Pipeline use wire rope hanging in
Below hydraulic support top beam on annulus, and fixing with wire clips, the outer pipeline heat insulation of canvas canopy uses rock wool heat-preservation,
Wrap up in glass fiber screen cloth, outer brush corrosion resistant coating.
(3) laying scheme installed by canvas
Use two-layer canvas 11, internal layer with insulation canvas, the airtight Tarpauling of outer layer, canvas a size of:
Long * width: 14 × 10m boundary zone eye, when canvas 11 covers hydraulic support 10, cloth length 14 meters is along southern and northern
To covering, wide 10 meters cover along east-west direction, owing to northern mining area northwester in winter is many, so canvas 11
Cover crimping direction to be considered, east-west direction arrange canvas 11 time, start from east westerly direction lay, second
Block pressure rides on first piece, when North and South direction arranges canvas 11, starts from south toward the north to laying, second piece
Pressure rides on first piece, and lap-joint uses strength universal glue bond to seal.
And canvas 11 edge eye is cascaded, at hydraulic support thing two along east-west direction by steel wire rope
End ground is fixed, fixed form: steel cord ends cyclization wire clips fixes, and beats φ 20mm eye on ground, dress
Enter M16 expansion bolt, with lockset screw-button, steel wire rope is connected with expansion bolt fastening.Steel wire rope is between east and west
Fixing 4 roads to hydraulic support top, each bottom hydraulic support 10 two ends fix 2 roads, North and South direction is every 2
One steel wire rope fixed by frame, and all steel wire rope lockset screw-buttons buckle.The edges and corners of hydraulic support 10 first to be used
Two-way stretching plastic net covered protection, then cover canvas 11.
Below hydraulic support 10 thing two end back timber at neutral, use long * width: 6*2.5m bar-mat reinforcement supports sail
Cloth 11, prevents canvas 11 wind-engaging from blowing, and shake acutely, causes the impaired air intake of friction, and powerful strength is permissible
Fly from interior outward canvas 11 being blown.Surrounding concrete cast high by 150 × wide 200 bottom hydraulic support 10 simultaneously
Dash platform 15, prevents peripheral water from flowing in hydraulic support canopy.
Canvas 11 covers after terminating, bottom hydraulic support 10 beyond surrounding dash platform 15, husky with knitting bagged
Soil pressure is Radix Saposhnikoviae on canvas 11, and north and south two end puts one layer, and thing two end places two layers of sandbag 16.Hydraulic support
10 construction of prevention work terminate.
(4) daily monitoring and maintenance
Stay one in protection canopy west side, a thermometer is installed, arrange special messenger to carry out observing hydraulic support protection
Canopy internal temperature, observed once every three days and makes a record, and analyzes simultaneously, sums up heating and outdoor temperature
Relation, adjust in time heating amount.When outdoor minimum temperature is more than-10 DEG C, heat gate valve standard-sized sheet, hydraulic pressure
Internal stent reaches 19 DEG C-21 DEG C, and after stopping heating, hydraulic support internal temperature is substantially at 9 DEG C of-12 DEG C of models
Enclose；When determining below-10 DEG C, just start hydraulic support is heated.Adjust indoor branch road heating amount in time,
Not stopping to test heating amount and the relation of outdoor temperature, finally determine that branch road stops 1/2, main total gate valve reaches 2/5
Position, even if outdoor, mining area minimum temperature reaches-37 DEG C, hydraulic support internal temperature can be controlled in 8 DEG C-10 DEG C
Between scope
The foregoing is only the preferred embodiment of the invention, not in order to limit the invention,
Any amendment, equivalent and the improvement etc. made within all spirit in the invention and principle, all should
Within being included in the protection domain of the invention.
