Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction ventilation, in particular to a ventilation device for partition construction in an inclined shaft. Background Art

[0002] In recent years, more and more long and large tunnels have been constructed. In order to achieve short tunnel construction and add excavation working faces, ventilation is an indispensable technical link in mechanized operations. In mechanized operations, ventilation supplies fresh air to the construction site in the tunnel, removes dust and various toxic and harmful gases, creates a good working environment, and ensures the health and safety of construction workers. At the same time, ventilation is also a necessary condition for maintaining the normal operation of electromechanical equipment in the tunnel. For various long tunnel construction, ventilation often plays an important and even decisive role in the construction plan and construction organization design of the entire project. At present, the usual practice for the construction ventilation of extra-long tunnels with multiple working faces is to excavate an inclined shaft obliquely connected to the tunnel above the tunnel at a certain length from the tunnel entrance, and an axial flow fan sucks fresh air into the inclined shaft mouth.

[0003] The existing ventilation duct inclined shaft is relatively long, and the single-end air supply distance of the inclined shaft duct ventilation is too long, which will cause excessive ventilation resistance and air leakage. In addition, in order to prevent dust inside the tunnel, a filter is generally installed in the ventilation duct. After long-term use, dust or other debris will be deposited in the filter holes on the filter. The process for users to remove the filter plate is cumbersome, time-consuming and labor-intensive.

[0004] Therefore, we proposed a ventilation device using partitions in inclined shafts to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The axial flow fan transports the external gas to the gas delivery pipe through the air guide pipe, and the gas is discharged through the exhaust pipe.
