Description

Tunnel cursor positioning transmitter

The invention relates to a tunnel cursor positioning emitter, in particular using laser light to divide a tunnel cross section into multi-angle blocks in a concise and fast way during tunnel excavation, so as to facilitate subsequent space gas detection.

It is generally necessary to dig tunnels in road construction in mountain areas, and it is well known that in the process of tunnel excavation, dangerous gases such as colorless, odorless gas or methane are often encountered. The gas is flammable and will be ignited to cause fire when excavated and rubbed against the rocks to produce sparks, or even explode to cause the tunnel to collapse and cause casualties. Methane is a toxic gas. A small amount of inhalation is enough to cause dizziness and coma, especially for those who come to the rescue.

Therefore, how to quickly and effectively analyze and detect such dangerous gases has always been the goal of the relevant industry efforts.

In the conventional technology, when a tunnel or corridor is to be inspected, a working ladder is first erected on the cross section of the tunnel or corridor, because the height of the tunnel or corridor may be several meters or more than ten meters, and then, The construction personnel carry the red spray and climb up the work ladder, calibrate the target position of the cross section with red spray paint to form a mark, and then, the inspector will move the detection instrument to the ground of the tunnel or corridor, according to the red spray paint The mark selects the target area, and then uses the sampler to aim at the target area for sampling, so that the detection instrument can perform real-time on-site detection.

Because the walls of tunnels or corridors are generally quite high, it is dangerous for construction workers to climb up and down repeatedly on the working ladder, and the ground of tunnels or corridors is not flat, so they are moved and placed The working ladder is not very convenient, especially when the lighting is quite limited.

Therefore, there is a great need for an innovative tunnel cursor positioning transmitter, which uses laser light to divide the tunnel cross section into multi-angle blocks in a concise and fast way during the process of tunnel excavation, so as to facilitate subsequent space gas detection.
