Survey system of shield tunnel and survey method of shield tunnel

摘要

Problem to be solved: to provide a shield tunneling survey system capable of easily measuring position and attitude of shield tunnel.SolutionShield tunneling 5 survey systemA laser scanner 12 for measuring spatial position information of a plurality of segments 7 including a plurality of segment targets 7T which are a part of a plurality of segments 7 by irradiating a plurality of segments 7 with laserOne of the plurality of reference points set in shield tunnel 5 is set at a reference pointA total station to measure the spatial coordinates of a laser scanner 12 based on other reference pointsA control device for calculating the position and attitude of the shield tunnel 5 based on the spatial coordinates of the plurality of segment targets 7T included in the spatial coordinates and spatial position information of the laser scanner 12 andWas provided.Diagram
