Abstract

The invention relates to a pipe jacking project automatic measurement system and a method thereof. The pipe jacking project automatic measurement system comprises auxiliary observation stations established at the turning positions in the pipe jacking construction. Each auxiliary observation station consists of an automatic leveled base and a measurement robot total station. A data terminal of each measurement robot total station is connected with a data port of a computer by a shielded cable. Measurement data is processed by the computer. Each total station is sequentially controlled by the computer to orderly carry out transfer measurement. According to the invention, measurement robots are adopted to be connected with the programmed computer and the computer commands each measurement robot to carry out automatic tracking measurement according to a program. The system and the method thereof can be used for conveniently and timely measuring actual coordinate values of a tool head in various curve pipe jacking projects.

Description

technical field [0001] The invention relates to a measuring system capable of measuring the coordinates of the actual working state of the tool head in real time in a pipe jacking project, especially a measuring system suitable for observing the pipes with small diameters, complex plane curves or vertical curves, and instrument base stations and tool heads. A measurement system in engineering where objects are not directly in line of sight. Background technique [0002] At present, in the measurement of straight-line pipe jacking engineering, the usual method is to measure the base station at a suitable position on the back seat of the working well, and ensure that the position can clearly see the target installed at the head of the tool head throughout the entire process of the project. Measure the coordinate value of the tool head head and compare it with the design coordinate value to determine the direction and value of the tool head that needs to be corrected. However,...
