Abstract
The invention relates to the technical field of mining security, and particularly relates to a method for constructing a mining impact-resisting sealed wall. The method adopts simpler and more convenient construction procedures, and light foam concrete is filled, so that the wall has the advantages of light weight, large bearing ability, strong flexibility, fire resistance and the like. The method is simple and convenient to construct, rapid in construction speed, good in construction effect; and the sealed wall has the advantages of good impermeability and good impact-resistance and fire-resistance.
Description
Technical field
The present invention relates to a kind of safety of coal mines technical field, be specifically related to the airtight wall construction method of a kind of mining protecting against shock.
Background technology
Traditional brick concrete closed wall, its shortcoming are that speed of application is slow, and labor strength is big; Because the fragility of self makes airtight body of wall produce the crack when top, tunnel group pressure is big easily, outwards discharges gas and other toxic gas; When bump takes place when, fire dam even can be broken through, impelling goes out concrete block; Near it workman and equipment are damaged the harm Safety of Coal Mine Production.
" sprayed-on plastic foam on the board wall " fire dam form of construction work, its shortcoming be airtight thin thickness, inleakage greatly, not firm, even influence daily ventilation operation, becoming influences the accident potential that mine safety is produced.
Summary of the invention
The objective of the invention is the deficiency to prior art, provide a kind of construction technology simple, speed of application is fast; Construction effect is good, and labor strength is low, and efficiency of construction is high; Has good protecting against shock, the airtight wall construction method of mining protecting against shock of resistance to compression and fire resistance.
The present invention realizes through following technical scheme for realizing above-mentioned purpose:
The airtight wall construction method of a kind of mining protecting against shock, the filler that adopts in the work progress is a light foam concrete, the concrete component of filling is made up of cement, silica flour, blowing agent and water.
May further comprise the steps:
(1) in the place of needs construction fire dam, top board, base plate and two walls are carried out slotting, beat wood siding wall at the rear of construction tunnel then, covered with plastic film, enclosing tunnel prevents spillage.
(2) in construction fire dam centre position top board, base plate and two wall places each make a call to four anchor poles; Be square; The anchor pole of top board and base plate uses the reinforcing bar suitable with bolt diameter to couple together, and wire binding is used in the joint, also is the same between two walls; Eight reinforcing bar contact positions are firm with wire binding, form a cage shape.
(3) beat wood siding wall construction side one side; Connect light foam concrete pumping interface, to the regional filling light foam concrete that is surrounded, always forming one is skeleton with anchor pole and reinforcing bar; Two wood siding wall spacings are thickness; The centre is full of the fire dam of light weight concrete construction, and construction is sealed the side of constructing after accomplishing.
The job location of step (1) has been selected in certain inclination angle, the oblique tunnel of bowing; Cut depth 300 ~ 500cm, wood siding wall are that 20 ~ 30cm is wide, and the Korean pine wooden peg that 2 ~ 3cm is thick becomes.
Anchor pole is mining 2200cm plain edition anchor pole in the step (2), and the anchor bolt construction position is positioned at the middle part of top board, base plate and wall; In construction fire dam centre position top board, base plate and two wall places each make a call to four anchor poles, anchor pole exposed length 500 ~ 700cm; Reinforcing bar is Φ 22 reinforcing bars, and steel wire is mining common bundle silk.
Constructed once in 8-12 hours, each light foam concrete construction depth is 800 ~ 1000cm.
Beneficial effect of the present invention is:
1, fire dam of the present invention is different with traditional fire dam construction, and construction technology is simple, and speed of application is fast, and construction effect is good, and labor strength is low, saves manpower greatly, raises labour efficiency.
2, the filler that adopts is a light foam concrete, and it has characteristics such as porous, flexibility is strong, deformability is big, belongs to inorganic material; Can not burn, thereby have good refractoriness, can guarantee the integrality of fire dam; Has antiknock; The function of protecting against shock has very high non-deformability, can effectively resist shock wave.Blast or during bump, the energy that can good absorption impacts prevents that fire dam from receiving concussion fracture and hurt sb.'s feelings.Can not burn.This fire dam can also change thickness of wall body according to field condition, and is tight-closed, firm, and protecting against shock and anti-pressure ability are strong.

The specific embodiment
Further specify technical scheme of the present invention below in conjunction with the accompanying drawing and the specific embodiment.
Combine Fig. 1 at present, Fig. 2, Fig. 3, Fig. 4 are the example explanation: at first build the place of fire dam, top board 1, base plate 3 and two walls 7 carried out slotting, beat wood siding wall 2 at the rear of construction tunnel then at needs, covered with plastic film, enclosing tunnel prevents spillage.The job location has been selected in certain inclination angle, the oblique tunnel of bowing; Cut depth 300 ~ 500cm, wood siding wall 2 is that 20 ~ 30cm is wide, the Korean pine wooden peg that 2 ~ 3cm is thick becomes.
In construction fire dam centre position top board 1, base plate 3 and two walls, 7 places each make a call to four anchor poles 4, be square, as shown in Figure 4; On anchor pole, do armature boring 9; The anchor pole 4 usefulness reinforcing bar 5 suitable with anchor pole 4 diameters of top board 1 and base plate 3 couples together, and tie up with steel wire 6 joint, also is the same between two walls 7; Tie up firmly with steel wire 6 eight reinforcing bar 5 contact positions, forms a cage shape.Anchor pole 4 is mining 2200cm plain edition anchor pole, and anchor pole 4 construction locations are positioned at the middle part of top board 1, base plate 3 and wall 7; In construction fire dam centre position top board 1, base plate 3 and two walls, 7 places each make a call to four anchor poles 4, anchor pole 4 exposed lengths 500 ~ 700cm; Reinforcing bar 5 is Φ 22 reinforcing bars, and steel wire 6 is mining common bundle silk.
One side beats wood siding wall 2 in the construction side; Connect light foam concrete pumping interface, to the regional filling light foam concrete 8 that is surrounded, always forming one is skeleton with anchor pole 4 with reinforcing bar 5; Two wood siding walls, 2 spacings are thickness, and the centre is full of the fire dam of light weight concrete construction 8.Construction is sealed the side of constructing after accomplishing.
