Abstract

The invention discloses a tunnel ventilation interflow system and a method for allocating and adjusting wind power, which is mainly to solve rationally allocation of ventilation of an excavating face tunnel. The system consists of two or three ventilation devices and a plurality of connected wind-cones and a plurality of valves, each ventilation device is formed by a wind-cone and a set of blowers, adjacent ventilation devices are connected by the connected wind-cones, and the plurality of valves are arranged in each wind-cone and each connected wind-cone. The tunnel ventilation interflow system and the method have the advantages that: the prior ventilation pipeline is networked, conveying direction and wind power intensity are allocated and adjusted by opening or closing a valve so as to form wind supply ways of one to one, one to many, many to one and many to many of a ventilator and an excavating face, which can realize effectively dispatching and allocation of the wind power.

Description

technical field

[0001] The present invention relates to tunnel ventilation, mainly to reasonably solve the adjustability of tunnel ventilation on the face of the tunnel. Background technique

[0002] In order to ensure that the working environment of the tunnel face complies with occupational health and safety standards during tunnel construction, it is required to ventilate the tunnel face. At present, it is generally used: connect one end of an air duct to a group of ventilators, and place the other end on the face of the tunnel. The length of the air duct increases with the continuous advancement of the tunnel face. Delivered to the face of the face, improving the air quality of the face of the face. That is to say, for a face, an independent ventilation device is composed of an air duct and a group of fans.

[0003] The ventilation of the two tunnels of the left and right separated double-lane tunnels requires two independent ventilation devices; the ventilation of the...
