Detailed Description
As shown in figure 1, the movable rapid drainage device for the tunnel excavation working face mainly comprises a water outlet pipe 1, a reducer union 2, a water inlet pipe 3 and an exhaust pipe 4.
The water outlet end of the water outlet pipe 1 is sleeved with the calandria 5 and is in fastening connection in a hoop binding mode, and the other end of the calandria 5 is led to a designated water drainage position. The water inlet end of the water outlet pipe 1 is in threaded connection with the large-mouth end of the reducer union 2. The small opening end of the reducer union 2 is in threaded connection with the water outlet end of the water inlet pipe 3. A valve 9 is welded at the middle part of the water inlet pipe 3, and the valve 9 is a ball valve. The water inlet end of the water inlet pipe 3 is welded with a filter screen 10, and the filter screen 10 is used for filtering water to a certain degree when being used for draining water. The water inlet end of the water inlet pipe 3 is connected with a water draining hose 6 (rubber pipe) in a hoop binding mode, and the water draining hose 6 stretches into the water accumulation pit. In addition, the upper end of the water outlet pipe 1 is welded and communicated with an exhaust pipe 4, and the axis of the exhaust pipe 4 is intersected with the axis of the water outlet pipe 1 and the included angle of the two is 20 degrees.
