Multiple hole packers are laterally placed equidistant in the drilling in tunnel both sides coal seam, and the drilling is logical as the infiltration of collection coal seam
Road, the hole packer are arranged on the port of drilling, for preventing coal seam infiltration from flowing into tunnel, outside each hole packer
End is both provided with branch drain, and one end of the branch drain is connect with hole packer, and the other end of the branch drain passes through company
It connects hose to be connected on drain header, and is connected with drain header；
The structure of the hole packer is：Including threaded expander pipe, connecting tube and screw thread self-locking pipe, the threaded expander pipe and
The both ends of screw thread self-locking pipe are both provided with hickey, and the threaded expander pipe is isometrical pipe, and matching rotation is inserted into drilling,
The screw thread self-locking pipe is conical pipe, and the screw thread self-locking pipe is screwed on the port of drilling, the osculum of the screw thread self-locking pipe
It holds diameter equal with the diameter of threaded expander pipe, one is connected to by connecting tube between the screw thread self-locking pipe and threaded expander pipe
It rises.
Valve is both provided on each branch drain.
The inner wall in the tunnel is provided with waterproof layer and hardened layer.
The utility model has an advantageous effect in that compared with prior art：The utility model by tunnel into coal seam
Infiltration in coal seam is focused in drilling to export in drain header by branch drain and be taken away, and at the end of drilling by drilling
Hole packer is set on mouthful, it is ensured that coal seam infiltration may not flow into tunnel, tunnel environment can not only be made to keep drying, and to tunnel
Structure does not influence.
Description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
In figure：1 it is drain header, 2 be branch drain, 3 be connection flexible pipe, 4 be hole packer, 41 is threaded expander pipe, 42
It is screw thread self-locking pipe for connecting tube, 43,44 be hickey, 5 be tunnel, 6 be coal seam, 7 be drilling, 8 be valve, 9 is waterproof
Layer, 10 are hardened layer.
Specific embodiment
As shown in Figure 1, a kind of pump drainage water system for coal mine roadway of the utility model, including drain header 1, draining branch
Pipe 2, connection flexible pipe 3 and hole packer 4, the drain header 1 are disposed longitudinally in tunnel 5, and multiple hole packers 4 are laterally equidistant
It is arranged in the drilling 7 in 5 both sides coal seam 6 of tunnel, as the channel for collecting coal seam infiltration, the hole packer 4 is set for the drilling 7
On the port of drilling 7, for preventing coal seam infiltration from flowing into tunnel 5, the outer end of each hole packer 4 is both provided with draining
Branch pipe 2, one end of the branch drain 2 are connect with hole packer 4, and the other end of the branch drain 2 is connected by connection flexible pipe 3
It is connected on drain header 1, and with drain header 1；
The structure of the hole packer 4 is：Including threaded expander pipe 41, connecting tube 42 and screw thread self-locking pipe 43, the screw thread
