Method and system for measuring gradient and rotation angle of shield tunneling machine, terminal and medium

Abstract

The invention belongs to the technical field of tunnel measurement, and discloses a gradient and rotation angle measurement method and system for a shield tunneling machine, a terminal and a medium. Determining the position relation between a slope plate and a line pendant according to the designed slope of a proposed tunnel, and marking the initial position of the bottom end of the line pendant after the slope plate is fixed; meanwhile, the gradient and the rotation angle of the shield tunneling machine located on the starting frame are manually measured, and the measurement result is compared with automatically measured and collected data; in the shield tunneling process, along with changes of the gradient and the rotation angle of the shield tunneling machine, the line pendant changes by means of the relative relation between the bottom of the gravity line pendant and the gradient plate, and the real-time gradient and the rotation angle of the shield tunneling machine are determined by measuring the variable quantity. Compared with a traditional mode, the manual measurement difficulty of the gradient and the rotation angle of the shield tunneling machine is reduced, and meanwhile the precision of a measurement result is improved. And manual measurement can be carried out quickly when the automatic measuring device of the shield tunneling machine goes wrong.

Description

technical field [0001] The invention belongs to the technical field of tunnel measurement, and in particular relates to a method for measuring the slope and rotation angle of a shield machine, a measurement system, an information data processing terminal, and a computer-readable storage medium. Background technique [0002] At present, with the development of automatic measuring instruments in recent years, in shield tunneling construction, automatic measuring systems are generally used for shield tunneling guidance. In order to ensure the measurement accuracy, manual re-measurement is an important part of construction survey, especially in long-distance tunnel construction, manual re-measurement is an important task to ensure smooth penetration. The slope and rotation angle of the shield machine are important parameters for manual measurement and re-measurement of the attitude and axis of the shield machine. During the construction process, regular manual re-measurement is...
