The invention belongs to the technical field of tunnel construction, in particular to a ventilation gas flexible start monitoring device in a tunnel construction. The ventilation gas flexible start monitoring device in the tunnel construction aims at solving the problems that in the prior art, a monitoring head is inconvenient to adjust, the monitoring effect is affected, tunnels cannot be supported at any time, and the treatment cannot be carried out when the gas concentration is too high. The ventilation gas flexible start monitoring device in the tunnel construction comprises a base plate and a top plate, wherein two first sleeves are fixedly connected to the bottom of the base plate, two partition plates are horizontally and fixedly connected between the two first sleeves, and a balance weight is slidably connected between the two partition plates; a stand column is arranged in each first sleeve in a screw-thread sleeving mode, and a pressing plate is fixedly connected to the bottom, below the first sleeve, of each stand column; and two baffle plates are vertically and fixedly connected to the top of the base plate, a transverse plate is movably connected between the two baffleplates, and a plurality of exhaust fans are separately and fixedly connected to the opposite sides of the two baffle plates. The ventilation gas flexible start monitoring device in the tunnel construction has good monitoring effect, can support the tunnels, accelerates gas circulation and reduces potential safety hazards.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a flexible start-up monitoring device for ventilation gas in tunnel construction. Background technique [0002] Tunnels are buildings built underground or underwater and laid with railways for the passage of locomotives and vehicles. According to their location, they can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. The tunnels that pass under mountains or hills are called mountain tunnels, the underwater tunnels that pass under rivers or seabeds to cross rivers or straits are called urban tunnels, and those that pass underground in cities to meet the needs of railways passing through large cities are called urban tunnels. Most of these tunnels are mountain tunnels. At present, gas monitoring devices are required to monitor gas during tunnel construction. [0003] However, the height and direction of the monitoring head in ...
