Abstract

The invention relates to the field of blasting, and particularly relates to a rotary measuring scale device capable of realizing accurate hole distribution in blasting construction and a hole distribution method. The rotary measuring scale device comprises a fixing module, a distance positioning module, an angle positioning module and a lifting module, wherein the fixing module is positioned at the bottom of the whole device; the bottom of the lifting module is connected with the fixing module; the top of the lifting module is connected with the angle positioning module; and the distance positioning module is arranged on the angle positioning module. By utilizing a polar coordinate axis principle, on the basis of determining a tunnel center line, a polar coordinate axis origin is set, thedevice is fixed, and the position of a blast hole is determined through a telescopic steel tape and an angle measuring device, so that the field construction can be in accordance with a blasting design scheme, manual operation errors are reduced, the blast hole distribution precision is improved, and the over-excavation and under-excavation of the blasting construction are avoided.

Description

technical field [0001] The invention relates to the field of blasting, in particular to a rotary measuring scale device and a hole-laying method capable of realizing accurate hole-layout in blasting construction. Background technique [0002] When carrying out tunnel blasting operations, it is necessary to arrange holes according to the design drawings and hole arrangement parameters in the blasting special construction. The spacing and the length of the minimum resistance line directly affect the shape of the tunnel, and precise control of the parameters can effectively reduce the advance excavation. For the layout of blastholes in on-site blasting construction, blasting engineers generally use total stations (theodolites) and measuring tapes to locate blasting holes based on their experience. However, due to the ups and downs and irregularities of the tunnel surface, as well as errors in manual measurement, large deviations in the positioning of hole spacing and row spaci...
