Abstract

The present disclosure relates to the construction of inclined shafts of tunnels, in particular to a fast-assembled tunnel ventilation partition structure. It includes a partition member arranged longitudinally along the inclined shaft of the tunnel, a ventilation channel is formed between the partition member and the vault of the inclined shaft, and support members for supporting the partition member are arranged on the inner walls of both sides of the tunnel along the longitudinal direction of the inclined shaft. The present disclosure can rationally utilize the structure of the tunnel itself by setting the partition member, and form an independent air inlet passage between the partition member and the top wall of the inclined shaft of the tunnel to achieve long-distance ventilation effect; combined with the partition structure, it is easy to assemble, The feature of easy maintenance reduces the impact of partition construction on the tunnel construction period.

Description

technical field [0001] The present disclosure relates to the construction of inclined shafts of tunnels, in particular to a fast-assembled tunnel ventilation partition structure. Background technique [0002] In order to improve the air quality in the tunnel during long-distance construction and ensure the physical and mental health of construction workers, mechanical ventilation is required, that is, fresh air is blown into the tunnel by machinery at one end of the tunnel, so that the fresh air is diluted and squeezed out along the longitudinal direction of the tunnel. Dirty air out. In the prior art, the fan is generally connected to the air pipe, and the air pipe is installed on the vault of the tunnel. However, when the distance of the inclined shaft is long, the air supply of the air pipe has high air leakage rate, large resistance along the way, and easy damage during construction. question. Contents of the invention [0003] In order to solve the above technical p...
