Wherein the smoke evacuation channels 121 ' are discontinuous, the waste water pump house 14 ' can be arranged by utilizing the space between two adjacent rows of smoke evacuation channels 121 '.
However, when the length of the common rail co-building tunnel is long, the subway smoke exhaust channel 121 ' needs to be arranged to penetrate in the longitudinal direction, and at this time, the smoke exhaust channel 121 ' conflicts with the space of the waste water pump room 14 '. For this purpose, it is usually the practice of the skilled person to remove a portion of the segment 4 'in the common rail co-constructed tunnel to dig up at the bottom or side of the common rail co-constructed tunnel, thereby forming a space for the waste water pump house 14'. However, this not only increases the construction difficulty, but also destroys the integrity of the segment 4' in the common rail co-constructed tunnel, thereby causing a certain safety risk.
In view of the above, the present embodiment provides a common rail co-constructed tunnel, which includes duct pieces 4, first partition walls 5, second partition walls 6 and a waste water discharge system 7, referring to fig. 1 and 2. The pipe piece 4 is arranged in an enclosing mode to form a tunnel space, and the first partition wall 5 divides the tunnel space into a subway interval 11, a pipe gallery and discharge flue 12 and an evacuation channel 13 which are arranged in parallel. The subway section 11 is arranged between the pipe gallery and the discharge flue 12 and the evacuation channel 13, the second partition wall 6 is arranged in the evacuation channel 13 in a surrounding mode to form a waste water pump room 14, and the waste water discharge system 7 is configured to discharge waste water out of the waste water pump room 14.
