Method and device for automatic monitoring of ventilation fluid velocity data in curved tunnel construction

Abstract

The application discloses a method and device for automatic monitoring of ventilation fluid velocity data in curved tunnel construction. The method includes: setting a fluid velocity monitoring array on the support structure of the curved tunnel. The fluid velocity detection array is composed of a plurality of fluid velocity detection units. The fluid velocity detection unit is telescopically arranged in the support structure; the fluid velocity monitoring array is used to collect the fluid velocity at multiple places in the cross-section of the curved tunnel. When collecting, multiple fluid velocity detection units protrude from the support structure; according to the curve The fluid velocity of the tunnel cross-section draws the actual fluid velocity distribution diagram of the curved tunnel cross-section; the curve tunnel is judged according to the minimum fluid velocity, the maximum fluid velocity and the fluid velocity distribution diagram of the curved tunnel cross-section monitored by multiple fluid velocity detection units Whether the fluid velocity meets the construction standard. The monitoring of the fluid velocity will not affect the tunnel construction, and it can accurately and quickly judge whether the fluid velocity of the tunnel meets the construction standards.

Description

technical field [0001] The invention relates to the technical field of curved tunnel construction, in particular to a method and device for automatically monitoring ventilation fluid velocity data in curved tunnel construction. Background technique [0002] During the construction of the curved tunnel, due to the relatively closed construction environment, the oxygen content is low, and dust, carbon monoxide and other substances will be generated during the excavation of the curved tunnel, which will cause harm to the health of the staff. In order to ensure the health of the staff To be safe, it is necessary to ventilate the curved tunnel. At present, the fluid velocity of the ventilation is monitored by the staff holding the fluid velocity meter, which consumes a lot of labor costs and is inefficient. It is impossible to monitor the fluid velocity of the curved tunnel in real time. It is necessary to automatically monitor the velocity data of ventilation fluid in curved tun...
