Embodiment Construction
[0018] refer to figure 1 , the present invention comprises ventilator 2 outside the hole that is positioned at inclined shaft entrance 1, wind storage room 4 and air compressor station 8 that are positioned at tunnel; An independent space formed outside the contour line, in which the wind storage room is airtight. The ventilator 2 outside the cave is connected with the inclined shaft wind belt 3 in the inclined shaft 17, and the inclined shaft wind belt extends horizontally through the tunnel into the wind storage room to provide fresh air to the wind storage room; multiple jet fans are arranged in the inclined shaft 17 14. Guide the dirty air 13 in the tunnel through the jet fan to discharge out of the tunnel from the inclined shaft. A transformer 9 is installed in the wind storage room for the operation of the ventilator 5 in the tunnel, and two ventilators are installed in the tunnel to provide fresh air in the opposite main attack direction 15 and auxiliary attack directi...

The invention discloses an inclined shaft ventilation based high pressure air supply system in a long tunnel hole. The inclined shaft ventilation based high pressure air supply system comprises a ventilator, an air storage chamber and an air compressor station, wherein the ventilator is located outside the hole and the air storage chamber is located in a tunnel; the ventilator which is located outside the hole is used for supplying the fresh air for the air storage chamber through an inclined shaft wind belt; two ventilators are arranged in the air storage chamber and used for supplying the fresh air for a main target direction and an auxiliary target direction respectively; the fresh air is supplied for the air compressor station through an auxiliary wind belt; the foul air is guided to be discharged out of the hole from an inclined shaft through a jet fan; the main target direction of the tunnel is provided with the air compressor station; a plurality of air compressors are arranged in the air compressor station and used for providing the high pressure power air for an working surface construction device through a high pressure air duct after connected in parallel.
Description
technical field [0001] The invention relates to a device for realizing high-pressure air supply in a tunnel by using inclined shaft ventilation in tunnel construction. Background technique [0002] Construction ventilation and high-pressure air supply are important supporting technologies for long tunnel construction. Whether the ventilation is smooth or not directly affects the health of construction workers, and the supply of high-pressure air affects the resource allocation of excavation. In the construction of long tunnels, these two issues have always been constraints Major problems with construction progress. The commonly used construction method is to set up a fixed air compressor station and ventilator outside the cave, and supply fresh air and high-pressure air to the working surface by pressing in. Although it can solve the problems in construction, there are still many disadvantages. [0003] Air is supplied by long-distance press-in mode. Due to the influence o...
