Description
Technical field
The present invention relates to the filling forming structure that a kind of filling mining or gob side entry retaining use, especially a kind of coal mine
Retrofilling bag shaped structure and its application method.
Background technology
In mineral industry, for carrying out gob side entry retaining with filler, the country uses movable steel form conduct at first
Construct thereafter as the raising of technology uses flexible filling bag instead as construct, and carries out gob side entry retaining by high-water material
Flexible filling bag is all made of in the ultrahigh water material goaf filling method of reference as filling construct.
Field engineering practice in using flexible filling bag carry out filling construct after, formation obturation can be with lane
The effect of road roof and floor pressure and expand deformation so that final filling effect is not satisfactory, and use flexible filling
Bag needs to formulate the size of filling bag, ununified standard model so that apply at scene according to the field condition of each coal mine
Work takes longer.
Invention content
In order to overcome the shortcomings of the prior art, a kind of underground coal mine filling bag shaped structure of present invention offer and its use
Method, the filling bag shaped structure itself has intensity and model standardizes, and expense can be speeded up the work and be reduced to application method
With.
The present invention solve its technical problem the technical solution adopted is that:
A kind of underground coal mine filling bag shaped structure, including girder truss wall, bag shaped structure surface encapsulation layer and bottom knot
Structure, the girder truss wall are formed by girder truss is framework superimposed, and the girder truss frame is by the completely the same purlin in four sides
Aggregate head and the tail of setting a roof beam in place are formed by connecting, and often arrange girder truss aggregate and are connected to form by multiple girder truss cell cubes are arranged in parallel, institute
The bottom for the girder truss cell cube stated is rectangle, and top surrounds by four triangles, and four vertexs of a triangle overlap as a bit,
And subpoint of this on the rectangle of bottom surface is two cornerwise intersection points of rectangle, and two vertex of triangular base and square
Four vertex of shape overlap successively, and rectangle only connects a diagonal line, and the rectangle diagonal line of adjacent truss beam element body connects phase
Instead;Girder truss wall is fixedly connected between the inner surface sealant of bag shaped structure surface encapsulation layer and outer surface sealant, together
When girder truss wall be mounted on bottom structure on.
A kind of application method of underground coal mine filling bag shaped structure, including following operating procedure:1) it is needing using filling
At the down well placement of bag shaped structure, ground is flattened, then steadily places bottom structure;2) the cooperation installation truss on bottom structure
Beam aggregate sets up a circle girder truss aggregate and forms girder truss frame, is superimposed multiple girder truss frames and eventually becomes one successively
Stifled girder truss wall;3) it when the height of girder truss wall reaches and contacted with roof, injects and fills at preset inlet
Filling chock material is completed after material solidification to be filled.
Compared with prior art, a kind of underground coal mine of the invention filling bag shaped structure and its application method, due to its filling
Bag shaped structure is formed by girder truss cell cube set, and specifically, girder truss cell cube constitutes girder truss aggregate, then by purlin
Aggregate of setting a roof beam in place forms girder truss frame, and final girder truss is framework superimposed at girder truss wall, and girder truss wall is arranged in bag
The filling bag shaped structure of the present invention is just constituted in shape body structure surface sealant and on bottom structure, injection thereto is filled
Filling chock material, the girder truss cell cube will produce outside expansionary force in the active force of top (i.e. internal) by obturation,
In girder truss wall under the anchor pole of horizontal drawing or the stretching action of anchor cable so that give internal one outside girder truss cell cube inwardly
Reaction force effect, power between the two cancels out each other, and the final filling forming structure can effectively control obturation
The dilatancy of the filling forming structure generated under compression force effect.As it can be seen that the present invention, which is itself, has intensity and type
Number standardized convenient filling forming structure so that for underground gob side entry retaining and the more universalness and height of filling mining technique
Using for effectization provides facility, and can reduce expense of colliery industry when with process above.

Intersection point, and two vertex of the bottoms triangle 1-2 overlap successively with four vertex of rectangle, rectangle 1-1 only connects one diagonally
The rectangle diagonal line connection of line, adjacent truss beam element body 1 is opposite;It is close that girder truss wall 3 is fixedly connected on bag shaped structure surface
Between the inner surface sealant 7 and outer surface sealant 8 of sealing, while girder truss wall 3 is mounted on bottom structure 4.This
The girder truss wall 3 and bag shaped structure surface encapsulation layer of sample invention are just gathered for an entirety, and compound template die is become
A kind of underground coal mine of plate fills bag shaped structure, and finished product directly sets up and applies in underground, convenient construction as standard component.
Fig. 1 to Fig. 5 shows the structural schematic diagram of a preferred embodiment of the invention.
Referring to Fig. 1, which is a rectangle 1-1, rectangle 1-1 long 548mm, wide 216mm, and truss element
The vertex of body is in center, and apart from rectangle 1-1 high 250mm, and top is surrounded by four triangle 1-2, four triangles
The vertex of 1-2 overlaps as a bit, and subpoint of this on the rectangle 1-1 of bottom surface is two cornerwise intersection points of rectangle 1-1,
And two vertex of the bottoms triangle 1-2 overlap successively with four vertex of rectangle 1-1, rectangle 1-1 only connects a diagonal line,
The rectangle diagonal line connection of the adjacent truss beam element body 1 of composition girder truss aggregate 2 is reversed;Truss element body can be
Steel construction, but not limited to this, it is also adapted to the material application with higher-strength.
Referring to Fig. 2,1 structure of girder truss cell cube girder truss aggregate 2 in a row, often arranges girder truss shown in figure 1 above
Aggregate 2 is connected to form by multiple girder truss cell cubes 1 are arranged in parallel, and welding may be used in the mode that is directly connected to often arranged, because
For present material selection steel, when selecting other to meet intensity and light composite material, between girder truss cell cube 1
Connection type is gluing.The structure is more prominent in order to which initial stage image is shown, spy enumerates to be combined by 6 girder truss cell cubes 1
Made of form, and in standard form later formed by the structure composite, i.e., final template is to arrange the structures by number to fold
Add, become a face wall, be convenient for underground transportation, underground further according to actual conditions by template splicing together, to
Achieve the purpose that finally to fill.
Referring to Fig. 3 and Fig. 4, based on the analysis of two above structure, set forms girder truss wall shown in final Fig. 3
3 effective structure figure, the girder truss wall 3 are formed by girder truss is framework superimposed, and the girder truss frame is by four sides
Completely the same 2 head and the tail of girder truss aggregate are formed by connecting, and girder truss wall 3 is fixedly connected on bag shaped structure surface encapsulation layer
Between inner surface sealant 7 and outer surface sealant 8 (as shown in Figure 3), girder truss wall 3 and bag shaped structure surface encapsulation layer
Connection type can be gluing or rivet clasp, but be not excluded for during actual production is used other can connection type, while girder truss
Wall 3 is mounted on bottom structure 4.In the engineering practice in later stage, and for the requirement of the sealing material of final products
It is waterproof, smooth and there is certain degree of hardness, such as duroplasts or glued board etc..
As shown in figure 4, bottom structure 4 is the fix stably structure of girder truss wall 3 in Fig. 3, the bottom structure 4 is
