Below in conjunction with specific embodiment, form of construction work of the present utility model is stated:
First, preparation of construction
1st, 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 monkey wrench and specification quincuncial plate etc..
2nd, material prepares: φ 159 seamless steel pipe 50m, φ 108 steel pipe 120m, φ 80 steel pipe 260m, φ 50 galvanized steel
Pipe 320m, canvas and each specification pipe fitting, auxiliary material.
2nd, 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.The 2nd, 3 row
End, the 1st row's hydraulic support 10 front-axle beam are pressed on the 2nd row's hydraulic support 10 caving shield by back timber end.
Making three row's hydraulic supports 10 that a ∩ shape is integrally formed from outside, North and South direction girth is minimum, reduces canvas 11 and uses
Amount.Canvas 11 after simultaneously covering tightly sticks together with hydraulic support 10 outline, little by shaking after wind, reduces and hydraulic pressure
The friction of support 10 is impaired.And at the 1st row with the cavity of the 2nd row's hydraulic support 10 top overlap joint formation, every frame North and South direction
Put two pieces of 3000*220*30mm (long * width * is thick) supporting plate 13.Do so is to allow hydraulic support 10 top be a plane, prevents the winter
Season hydraulic support 10 top cavity 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；Radiating tube 123 is adopted
Processing about 1.2 meters with ore deposit φ 159 waste material, both sides 0.6 steel plate blocks, and arranges one every 3 framves；Drainpipe 124 is adopted
Connect with φ 50 coating steel pipe pipe fitting, often arrange, below hydraulic support 10, road arm 122, totally 3 tunnel is installed.
All pipelines and processing weldment workshop welding processing, Assembling；Pipeline uses wire rope hanging to prop up in hydraulic pressure
Below frame back timber on annulus, and fixing with wire clips, the outer pipeline heat insulation of canvas canopy uses rock wool heat-preservation, wraps 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 marginal belt eye, when canvas 11 covers hydraulic support 10, cloth length 14 meters covers along North and South direction, wide 10 meters along between east and west
To covering, owing to northern mining area northwester in winter is many, so canvas 11 covers crimping direction to be considered, east-west direction arranges canvas
When 11, start from east westerly direction lay, second piece of pressure rides on first piece, North and South direction arrange canvas 11 when, start from south
Toward the north to laying, second piece of pressure rides on first piece, and lap-joint uses strength universal glue bond to seal.
And canvas 11 edge eye is cascaded along east-west direction by steel wire rope, on ground, hydraulic support thing two ends
Fixing, fixed form: steel cord ends cyclization is fixed by wire clips, beat φ 20mm eye on ground, load M16 expansion bolt, with lock
Steel wire rope is connected fastening by tool screw-button with expansion bolt.4 roads, hydraulic support are fixed in steel wire rope east-west direction hydraulic support top
Each bottom 10 two ends fixing 2 roads, North and South direction fixes one steel wire rope every 2 framves, and all steel wire rope lockset screw-buttons buckle.Liquid
Two-way stretching plastic net covered protection first to be used in the edges and corners of pressure support 10, then covers canvas 11.
Below hydraulic support 10 thing two end back timber at neutral, use long * width: 6*2.5m bar-mat reinforcement supports canvas 11, anti-
Only canvas 11 wind-engaging blows, and shake acutely, causes the impaired air intake of friction, and canvas 11 can be blown outward by powerful strength from interior
Fly.High by 150 × wide 200 dash platforms 15 of surrounding concrete cast bottom hydraulic support 10 simultaneously, prevent periphery water from flowing into hydraulic pressure and prop up
In frame canopy.
Canvas 11 covers after terminating, and bottom hydraulic support 10 beyond surrounding dash platform 15, is pressed in sail with knitting bagged sandy soil
On cloth 11 windproof, north and south two end puts one layer, thing two end place two layers of sandbag 16.Hydraulic support 10 construction of prevention work terminates.
(4) daily monitoring and maintenance
Stay one in protection canopy west side, a thermometer is installed, arrange special messenger to carry out observing inside hydraulic support protection canopy
Temperature, observed once every three days and makes a record, and analyzes simultaneously, sums up heating and the relation of outdoor temperature, adjusts in time and supply
Warm amount.When outdoor minimum temperature is more than-10 DEG C, heat gate valve standard-sized sheet, reaches 19 DEG C-21 DEG C, work as stopping inside hydraulic support
After heating, hydraulic support internal temperature is substantially 9 DEG C of-12 DEG C of scopes；When determining below-10 DEG C, just start to hydraulic support
Heating.Adjust indoor branch road heating amount in time, do not stop to test the relation of heating amount and outdoor temperature, finally determine that branch road is stopped
1/2, main total gate valve reaches 2/5 position, even if the outdoor minimum temperature in mining area reaches-37 DEG C, hydraulic support internal temperature is controlled
System is between 8 DEG C of-10 DEG C of scopes.
The foregoing is only the preferred embodiment of the invention, not in order to limit the invention, all at this
Any modification, equivalent and the improvement etc. made within the spirit of innovation and creation and principle, should be included in the invention
Protection domain within.
