Problems solved by technology
[0003] Since the tunnel is a narrow and long chamber space structure, press-in ventilation is often used for tunnel ventilation during construction. The traditional ventilation pipe is at the intersection of the tunnel, and the bifurcation is easily separated by flexible ventilation to realize simultaneous air supply and ventilation. Stopping the wind at the same time, there is a great waste of reasonable application of fan efficiency, and the air volume cannot be adjusted

The invention relates to a novel tunnel ventilation connection pipe. The novel tunnel ventilation connection pipe comprises an air inlet and air outlets, wherein the air outlets include a first air outlet and a second air outlet; the air inlet is communicated with the first air outlet and the second air outlet through pipelines; an adjustment mechanism is arranged at one end close to each of the first air outlet and the second air outlet; the adjustment mechanism comprises air plates, a steering gear and a screw rod; the air plates are distributed on the two sides of each steering gear; one end of each air plate is fixed in the center of the steering gear while the other end of the air plate is connected with a side wall of the air outlet; the screw rod runs through the air outlet and is engaged with the steering gear; and a rotatable part is arranged at one end of the screw rod. The invention mainly aims to provide the novel tunnel ventilation connection pipe capable of controlling the air volume and the air direction of the air outlet through external adjustment for the defects in the prior art.
Description
technical field [0001] The invention relates to tunnel ventilation, in particular to a bifurcated ventilation connection cylinder with adjustable air volume and air direction. Background technique [0002] With the acceleration of my country's railway construction, a characteristic of tunnel engineering construction is highlighted. The length of the tunnel is getting longer and longer. It is necessary to set up multiple auxiliary tunnels to form the long tunnel into a "long tunnel and short tunnel" mode, and then the auxiliary tunnels will be converted to the main line. Multiple intersection areas will be formed. [0003] Since the tunnel is a narrow and long chamber space structure, press-in ventilation is often used for tunnel ventilation during construction. The traditional ventilation pipe is at the intersection of the tunnel, and the bifurcation is easily separated by flexible ventilation to realize simultaneous air supply and ventilation. At the same time, if the wind ...
