Description
Technical field
The utility model relates to a kind of civil engineering structure, particularly a kind of plugging device.
Background technology
In pit mining process, a large amount of gas can be there is in mine, and these gas need to be drawn out of by extraction technology, to recycle, gas pumping technology is generally first hole in coal seam, is secondly sent in boring by drawing-off gas pipe, finally carries out sealing of hole again.Owing to there is certain gap between gas exhaust pipe and drill hole wall, if carry out shutoff to these gaps not in time, and ensure the closely knit of shutoff, just likely there is ventilative gap, so just in time more gas cannot be extracted out, waste the energy.Therefore, the quality of shutoff determines gas pumping effect, so need a good plugging device to complete this shutoff work, makes it reach best plugging effect.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provides a kind of and has the good performance that is tightly connected, and location and exhaust effect all clearly, simplify shutoff slip casting work, ensure that the plugging device of shutoff compactness.
To achieve these goals, the technical solution adopted in the utility model is such: plugging device of the present utility model, comprise drainage tube, drainage tube upper surface and soffit place are all provided with comb, be slidably connected between comb and drainage tube, shutoff pipe is provided with in drainage tube, shutoff pipe is two, two shutoff pipe one end are connected with an exhaust plant through a sealing of hole band and a location-plate respectively, and shutoff pipe and exhaust plant are connected, sealing of hole band top is arranged through shutoff pipe, be connected with a Grouting Pipe bottom it, sealing of hole band adopts plastic cement sealing of hole band, location-plate adopts two half elliptic plates to be spliced.
Further, as a kind of concrete form of structure, drainage tube described in the utility model adopts PVC plastic glue material to make.
Further, as a kind of concrete form of structure, the comb length of drainage tube upper surface described in the utility model is less than the comb length of described drainage tube soffit.
Further, as a kind of concrete form of structure, one end of the relative exhaust plant of shutoff pipe described in the utility model is provided with grouting plug.
Further, as a kind of concrete form of structure, Grouting Pipe length described in the utility model is between three to five centimetres.
Further, as a kind of concrete form of structure, location-plate described in the utility model is provided with positioning bolt.
Compared with prior art, the utility model has the advantage of: this plugging device has the good performance that is tightly connected, location and exhaust effect are all clearly, simplify shutoff slip casting work, ensure that shutoff compactness, improve negative pressure of suction simultaneously, install also very convenient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure: 1. drainage tube; 2. comb; 3. shutoff pipe; 4. sealing of hole band; 5. location-plate; 6. Grouting Pipe; 7. exhaust plant.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The preferred embodiment of the utility model plugging device as shown in Figure 1, comprise drainage tube 1, drainage tube 1 upper surface and soffit place are all provided with comb 2, be slidably connected between comb 2 and drainage tube 1, shutoff pipe 3 is provided with in drainage tube 1, shutoff pipe 3 is two, two shutoff pipe 3 one end are connected with an exhaust plant 7 through a sealing of hole band 4 and a location-plate 5 respectively, and shutoff pipe 3 and exhaust plant 7 are connected, sealing of hole band 4 top is arranged through shutoff pipe 3, be connected with a Grouting Pipe 6 bottom it, sealing of hole band 4 adopts plastic cement sealing of hole band, location-plate 5 adopts two half elliptic plates to be spliced, described drainage tube 1 adopts PVC plastic glue material to make, comb 2 length of described drainage tube 1 upper surface is less than comb 2 length of described drainage tube 1 soffit, one end of the relative exhaust plant 7 of described shutoff pipe 3 is provided with grouting plug, described Grouting Pipe 6 length is between three to five centimetres, described location-plate 5 is provided with positioning bolt.
Plugging device of the present utility model has the good performance that is tightly connected, and location and exhaust effect all clearly, simplify shutoff slip casting work, ensure that shutoff compactness, improve negative pressure of suction simultaneously, install also very convenient.Described drainage tube 1 adopts PVC plastic glue material to make, and result of use is better; Comb 2 length of described drainage tube 1 upper surface is less than comb 2 length of described drainage tube 1 soffit, reasonable in design, and comb easy to use 2; One end of the relative exhaust plant 7 of described shutoff pipe 3 is provided with grouting plug, is convenient to carry out slip casting shutoff to shutoff pipe 3; Described Grouting Pipe 6 length is between three to five centimetres, and slip casting effect is better; Described location-plate 5 is provided with positioning bolt, further increases polarization.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
