Abstract

The invention discloses a tunnel section wind speed measuring device and a measuring point position calculation method. The measuring device includes a vertical measuring rod, a base and a wind speed measuring wind cup; the base includes a frame, the inner side face of the frame is provided with a sliding groove, and the vertical measuring rod is connected with the sliding groove of the base in a sliding mode through a prism base body arranged at the bottom of the vertical measuring rod; the wind speed measuring wind cup is fixedly arranged on the vertical measuring rod, determines the position arrangement according to the Log-Tchebycheff method, can rapidly and conveniently collect wind speeds at different positions of the same tunnel section and can rapidly move so as to quickly measure wind speeds at different positions of the next tunnel section. The problems that a test result is distorted and supports are difficult to arrange and inconvenient to move in the tunnel section wind speed measuring process are solved.

Description

technical field [0001] The patent of the present invention relates to the field of tunnel engineering measuring instruments, in particular to a tunnel section wind speed measuring device and a method for calculating positions of measuring points. Background technique [0002] The determination of the resistance coefficient of the tunnel wall, the measurement of the tunnel ventilation effect, and the on-site measurement of the tunnel fan personality curve are of great significance to the ventilation and energy-saving operation of the tunnel project. The most important measurement item in these items is the measurement of wind speed at the tunnel section. [0003] The traditional cross-section wind speed measurement mostly uses a single hand-held anemometer to measure the wind speed at individual points in the tunnel, and the average value is used as the average wind speed of the entire cross-section. The number of measuring points selected by this measurement method is relat...
