Problems solved by technology

[0003] The taxiways and runways in the airport are restricted areas, and the construction monitoring must meet the requirements of aircraft take-off and landing restrictions, and also ensure the coverage, frequency and accuracy of monitoring. The existing manual monitoring cannot be implemented due to airport operation restrictions; airport taxiways 1. The structure of the apron is solid, and conventional monitoring methods cannot truly reflect the stratum and surface settlement, and cannot provide real and reliable monitoring data for tunneling under the shield machine

Embodiment 1

[0027] This embodiment takes the construction of TA01 mark off of the Nanjing South Station to Lukou Airport Section of the Nanjing-Gaochun Intercity Express Railroad as an example. The specific steps are as follows figure 1 ,for:

[0028] A. Set up an automatic detection high platform next to the monitoring area (using scaffolding to set up an automatic detection high platform, simple structure, low cost, convenient disassembly and assembly), install a total station on the automatic detection high platform;

[0029] Establish 2 high-level monitoring platforms for instruments (ie, automatic detection of high-level platforms), using Leica total station (Laica TCRP1201+ instrument, with functions such as motor drive, automatic sight measurement, and infrared ranging without cooperative targets), which can be set on the road surface Adjacent to the high place that is visible to the monitoring range, the instrument is programmed to drive the instrument to a predetermined position, and t...

Abstract

The invention relates to the construction field of excavation of tunnels under airports, in particular to a full automatic high-frequency ground settlement monitoring method for an airport. The full automatic high-frequency ground settlement monitoring method comprises the following steps of A, arranging an automatic detection overhead platform besides a monitoring area, and mounting a total station on the automatic detection overhead platform; B, arranging a plurality of monitoring points in an array of a monitoring area; C, using a point jumping method to measure the monitoring points in a triangular elevation way, and monitoring the change of the height. The full automatic high-frequency ground settlement monitoring method for the airport has the advantages that the actual condition can be reflected by the monitoring data, the monitoring process meets the takeoff and landing limiting requirements of the aircraft, and the monitoring cost is reduced.

Description

Technical field [0001] The invention relates to the construction field of tunnel excavation under the airport, and in particular to a method for fully automatic high-frequency ground settlement monitoring used in the airport. Background technique [0002] When it is necessary to construct a passage through an existing airport, the only option is to set up a tunnel under the airport. When a tunnel is set up underground, it is necessary to monitor the surface settlement above the construction site at any time to ensure the normal use of the airport; [0003] Taxiways and airstrips in the airport are prohibited areas. Construction monitoring must meet the aircraft's take-off and landing restrictions, and the coverage, frequency and accuracy of monitoring must be ensured. The existing manual monitoring cannot be implemented due to airport operation restrictions; airport taxiways , The apron structure is sturdy, and conventional monitoring methods cannot truly reflect the ground and sur...
