Abstract
The utility model discloses a kind of recoverable gas pumping sealing of hole and filled opening device, comprise: drainage holes, gas pumping pipe, connecting hose, two-sided Grouting Pipe, slip casting baffle plate, grouting port, slip casting connecting leg, grouting pump, slip casting cylinder, sealing of hole mud, described gas pumping pipe is arranged in drainage holes, and the hole between its drainage holes port part and gas pumping pipe is blocked up by sealing of hole mudding; Described connecting hose is connected with gas pumping pipe; Described two-sided Grouting Pipe is arranged in the crack place of drainage holes surrounding, is connected with slip casting baffle plate.Slurries are injected in the crack of drainage holes surrounding by the inside and outside hyperboloid of two-sided Grouting Pipe by this device, and filled opening, carries out grout cures sealing of hole to the part within sealing of hole mud simultaneously, thus greatly increases extraction efficiency.Simultaneously after slip casting completes, visible two-sided Grouting Pipe recycling, can reduce the cost of injection hole sealing.
Description
Technical field
The utility model relates to a kind of hole sealing device, particularly relates to gas pumping sealing of hole and fills aperture surrounding slit device.
Background technology
Comparatively large for gas sealing of hole mode at present, but these hole sealing technologies are only the space between shutoff gas pumping pipeline and drainage holes mostly, do not carry out filling shutoff to the crack of drainage holes surrounding.Thus cause China about to have the stope Gas pre-drainage concentration of 65% lower than 30%, fully reflect the present situation of current China mash gas pumping drilling sealing quality difference.
Though there was existing hole sealing technology to carry out filling shutoff to the crack of drainage holes surrounding in recent years, but because the unreasonable crack filling effect that causes of device design itself is not good, cause gas still not high at extracting result, and these hole sealing devices cannot reclaim, thus also increase the cost of sealing of hole.
Utility model content
The purpose of this utility model is to provide a kind of recuperable gas pumping sealing of hole and filled opening device, solves current sealing of hole poor effect, and hole sealing device such as cannot to reclaim at the shortcoming.
The utility model solves the scheme that its technical problem adopts: this gas pumping sealing of hole and filled opening device comprise: drainage holes, gas pumping pipe, connecting hose, two-sided Grouting Pipe, slip casting baffle plate, grouting port, slip casting connecting leg, grouting pump, slip casting cylinder, sealing of hole mud, described gas pumping pipe is arranged in drainage holes, and the hole between its drainage holes port part and gas pumping pipe is blocked up by sealing of hole mudding; Described connecting hose is connected with gas pumping pipe, thus by methane gas extraction to extraneous; Described two-sided Grouting Pipe is arranged in the crack place of drainage holes surrounding coal body or rock mass, is connected with slip casting baffle plate; Described grouting port is arranged on slip casting baffle plate, and its one end is connected with two-sided Grouting Pipe, and the other end is connected with grouting pump by slip casting connecting leg; Described grouting pump is connected with slip casting cylinder.
Described sealing of hole mudding hole length is at 0.2 ~ 0.4m.
Described two-sided Grouting Pipe is that the Cylinder Surface of two radius difference 10mm is formed, the complete seal welding in one end of two Cylinder Surfaces is on slip casting baffle plate, the other end is by circular ring type iron plate welded seal, pore diameter size on two Cylinder Surfaces is 2 ~ 4mm, pitch-row is 5 ~ 8mm, its surface bus length is not less than 0.6m, and its subsequent corrosion is 1.1 ~ 2 times of drainage holes radius.
The beneficial effects of the utility model: slurries are injected in the crack of drainage holes surrounding by the inside and outside hyperboloid of two-sided Grouting Pipe by this device, filled opening, grout cures sealing of hole is carried out to the part within sealing of hole mud simultaneously, thus greatly increase extraction efficiency.Simultaneously after slip casting completes, visible two-sided Grouting Pipe recycling, can reduce the cost of injection hole sealing.
Accompanying drawing explanation
Fig. 1 is slip casting structural representation of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is the structural representation of the utility model side;
Fig. 4 is the structural representation in the utility model front.
In figure: the negative camber of 1-drainage holes, 2-gas pumping pipe, 3-connecting hose, the two-sided Grouting Pipe of 4-, 5-slip casting baffle plate, 6-grouting port, 7-slip casting connecting leg, 8-grouting pump, 9-slip casting cylinder, 10-coal body or rock mass, 11-crack, 12-sealing of hole mud, 13-hyperboloid Grouting Pipe, the positive camber of 14-hyperboloid Grouting Pipe, 15-circular ring type iron plate.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.
As shown in figures 1-4, the diameter gas pumping pipe (2) more smaller than drainage holes (1) is inserted in drainage holes (1), then the hole between sealing of hole mud (12) shutoff drainage holes (1) and gas pumping pipe (2) is used, get the diameter aperture identical with two-sided Grouting Pipe (4) footpath to coal body or rock mass (10) puncher again, the degree of depth of punching is identical with the bus length of two-sided Grouting Pipe (4) curved surface.After completing punching, by in two-sided Grouting Pipe (4) patchhole, slip casting baffle plate (5) is fixed on coal body or rock mass (10), then with slip casting connecting leg (7), grouting pump (8) is connected with grouting port (6), carry out slip casting.
After completing the filling shutoff to crack (11), slip casting connecting leg (7) is unloaded in grouting port (6), then slip casting baffle plate (5) and two-sided Grouting Pipe (4) are unloaded.Now just complete whole slip casting process.
