Abstract

The invention relates to a method for automatic contact survey of an ultra-deep vertical shaft, which comprises the following steps of: 1) designing survey stations for automatic contact survey, and installing a forced centering survey frame at each survey station; (2) erecting a total station with an automatic measurement function on a known observation station on one side of a shaft mouth, and selecting another known point in the ground control network to erect a prism as a rear view point; a plurality of total stations with an automatic measuring function being erected on the shaft wall of a vertical shaft, the total stations with the automatic measuring function being erected at the bottom of the vertical shaft to serve as shaft bottom starting measuring stations, and prisms being erected at the positions, close to a shaft mouth, in a tunnel to serve as shaft bottom forward-looking measuring points; (3) connecting a notebook computer with a wireless data transmission module to carry out online debugging, and adjusting parameters of the total station, the prism device and software; and (4) controlling an observation station of a total station with an automatic measurement function erected above the well by a notebook computer program, and completing one-time transmission of the vertical conductor from the known point above the well to the underground starting measurement point to obtain the direction and coordinates of the underground starting measurement station.

Description

technical field [0001] The invention relates to the technical field of wire measurement for underground tunnel engineering, in particular to a method for automatic connection measurement of ultra-deep shafts. Background technique [0002] With the development of the national economy, the infrastructure construction needs of major cities in China, in order to ensure the livelihood of the people, more and more electricity, water supply, and transportation projects in the form of underground pipes and tunnels are constantly being carried out. Pipeline and tunnel projects continue to emerge. In order to meet the design requirements of underground tunnel excavation, engineering survey work is becoming more and more difficult. It is imminent to study and do a good job of surveying work that can meet the needs of construction. Underground pipe tunnel construction survey includes: ground control survey, Compared with the existing measurement technology, the main difficulty in these ...
