Embodiment Construction

[0018] The present invention is further described below in conjunction with specific embodiment:

[0019] An inclined well-assisted tunnel partition ventilation system, the tunnel includes a main tunnel 1 and an inclined shaft 2, the inclined shaft 2 communicates with the main tunnel 1, and an axial partition is arranged inside the inclined shaft 2 and the main tunnel 1 3. The partition 3 divides the main tunnel 1 into an upper normal tunnel 11 and a lower normal tunnel 12, and the partition 3 divides the inclined shaft 2 into an upper inclined shaft 21 and a lower inclined shaft 22. The upper normal tunnel 11 It communicates with the lower main hole 11 near the face 4, the upper inclined shaft 21 communicates with the upper main shaft 11, the lower inclined shaft 22 communicates with the lower main shaft 12, and the upper inclined shaft 21 and the lower inclined shaft 22 The other end of each is connected with the outside world, a jet fan 5 is arranged in the upper inclined s...

Abstract

The invention discloses an inclined well-assisted tunnel partition ventilation system. The tunnel includes a main tunnel and an inclined shaft, the inclined shaft communicates with the main tunnel, and an axial partition is arranged inside the inclined shaft and the main tunnel. The partition board divides the main tunnel into an upper normal tunnel and a lower normal tunnel, and the axial flow fan sends the air flow to the vicinity of the tunnel surface through the air duct. The upper inclined shaft communicates with the upper normal tunnel, and the lower inclined shaft communicates with the lower The main hole is connected, and the other ends of the upper inclined shaft and the lower inclined shaft are connected with the outside world. A jet fan is arranged in the upper inclined shaft, and an axial flow fan is arranged in the upper main hole. The invention divides the inner space of the tunnel into upper and lower parts through partitions. The ventilation system of the upper main tunnel for air supply and the lower main tunnel for exhaust air saves tunnel space, has large air supply volume, convenient and flexible layout, and is more suitable for growing complex Ventilation of the tunnel.

Description

technical field [0001] The invention relates to an auxiliary ventilation system for tunnel construction, in particular to an auxiliary tunnel partition ventilation system for inclined shafts. Background technique [0002] The ventilation system is an important part of the tunnel construction and operation process. The reasonable layout of the ventilation system affects the ventilation quality in the tunnel, the air flow control in the event of a fire, the construction work environment, the personal safety of construction personnel, and the normal operation of mechanical equipment. run. Due to the closed nature of the tunnel environment, the air circulation in the tunnel is slow, the dust and smoke caused by blasting and other constructions are not easy to dissipate, and the concentration of pollutants is high. Therefore, a reasonable ventilation method is an effective guarantee for the safe construction of the tunnel. [0003] The traditional tunnel ventilation adopts the ...
