Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of quick grouting filling bag (referring to figures 1-3) in goaf synchronous with coal cutting of the utility model, including bag body
1, the top of the bag body 1 can rise top-type by the formation of pleated structure 9, and 9 internal upper part of pleated structure, which crosses, is provided with secondary injection
Pipe 8 is starched, the outer wall surrounding of the bag body 1 is provided with connector 6, and connector 6 is velcro or shackle etc.；The bag body
1 leading flank is vertically arranged with several aqueducts 4, is provided with several internal drainages on the face that bag body 1 is in contact with aqueduct 4
The outer wall bottom of aperture 5, each aqueduct 4 is provided with drainage hole 3, and the filler in bag will be filled by being realized by internal drainage aperture
Precipitating wash rice be discharged discharge, be discharged by the drainage hole of water guide bottom of the tube, keep obturation fine and close, to improve the support to top plate
Ability；The leading flank top center position of bag body 1 is provided with injected hole 2, the rib up and down of the leading flank of the bag body 1 and centre
It is arranged at intervals with bar pipe 7.
The utility model is cuboid, the same mining thickness of height, and width design is that 1 times of (or several times) coal cutting is cut deeply, this
Sample can realize that filling is synchronous with coalcutter coal cutting, often cut a knife (or number knife) coal, fill the goaf of identical drilling depth；Its length
It is designed as one group moving hydraulic support range, i.e., one group moving hydraulic support quantity × single hydraulic support width designs in this way
It is advantageous in that realization filling is synchronous with moving hydraulic support, one group hydraulic support of every Forward fills the goaf of same range,
It is synchronous with moving hydraulic support progress to realize filling progress.
The utility model outer wall is provided with velcro, it can be achieved that, realization Nian Jie with the velcro in existing obturation bag wall
It is continuously closely connect with neighbour row and adjacent bag, forms continuous obturation, improve goaf filling support effect, realize quick hanging bag peace
Dress；Rear side relies on neighbouring existing obturation, and connecting rod 10 is worn by bar pipe in front side, and will be vertically connected with bar 10 and be individually fixed in
Top plate or bottom plate, middle brace rod 10 are limited by connecting band, are realized without the quick mortar depositing construction of template.
The utility model bag body upper design has and can rise top-type, and can rise top internal upper part design has secondary grouting hose, in order to
Adapting to coal seam or mining height may change, i.e., the height in goaf may change in a certain range, and filling bag is to process in advance
Finished product, height is fixed, and can rise top and be advantageous in that rises it until coming into full contact with top plate by slip casting, to adapt to certain
The height change of range；Grouting filling object will form a small amount of remaining space after wash rice water densification contraction, soft by secondary grouting
Pipe carries out secondary grouting to remaining space, can further improve circularity and connects top rate, to further increase the branch to top plate
Support effect.
The installation process (referring to fig. 4) of the utility model:
Before moving hydraulic support process, Nian Jie with upper row filling bag wall on rear side of bag, liquid relief pressure branch will be filled by velcro
After frame process, connecting rod is penetrated in bar pipe on front side of filling bag, upper rib connecting rod is fixed on top plate using holdfast 11, by lower rib
Connecting rod is fixed on bottom plate, passes through, the centering Nian Jie with upper row's obturation bag wall by middle brace rod of connecting band 12 and its velcro
Between connecting rod limited, then drainpipe 15 is connect with the drainage hole on front side of bag body, completes the installation of filling bag.Finally, will
Slip casting is carried out with the injected hole on front side of the insertion filling bag of grouting gun 14 that Grouting Pipe 13 is connect by threeway, until filling bag is infused
