GPS positioning-based settlement monitoring device and monitoring method

Abstract

The invention provides a GPS positioning-based settlement monitoring device and monitoring method. The device is characterized in that multiple static force level gauges arranged on concrete bases areincluded, and one of the static force level gauges serves as a datum point static force level gauge; a static GPS measurement terminal is arranged beside the datum point static force level gauge; allthe static force level gauges are mutually communicated through a liquid introduction communication pipe and a gas introduction communication pipe; and sensors in all the static force level gauges and the static GPS measurement terminal are all connected with an upper computer. By adopting the device to conduct height measurement on monitoring points, the advantages of being high in measurement precision and operation efficiency, capable of achieving automated real-time monitoring and the like are achieved compared with traditional leveling and trigonometric height measurement methods; compared with a single GPS measurement method, the device has the advantages that the multi-point height measurement and monitoring functions are achieved only by adopting one terminal, and therefore the equipment input cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of construction engineering monitoring, in particular to a vertical displacement monitoring method for large storage tanks, dams, nuclear power plants, high-rise buildings, foundation pits, roadbeds, bridges and subway projects. Background technique [0002] In order to fully guarantee the quality of the project and the personal safety of the operators, it is particularly important to monitor important parameters and indicators in real time during the construction process of the project. With the development of construction technology, automated monitoring equipment is gradually being applied and has become a powerful means in the field of engineering monitoring. The static level is widely used as a compact instrument for measuring the relative elevation change between two or more points. It belongs to the construction engineering settlement displacement monitoring equipment. Due to its high precision, it has been wid...

AI Technical Summary

Problems solved by technology

[0003] There are obvious shortcomings in the use of the static level. It can easily measure the differential settlement between each monitoring point and the reference point, but it is difficult to obtain the absolute settlement of the monitoring point.

In order to obtain the absolute settlement of the monitoring point, the reference point must be set at a position that is not affected by the settlement. In order to ensure that the reference point is not affected by the settlement of the engineering construction, it must be far away from the construction site, which increases the difficulty of construction and maintenance.
