Integrated remote settlement observation station and its installation method

Abstract

The invention discloses an integrated remote settlement observation station and an installation method thereof. The observation station comprises a lengthened measuring rod, an embedded supporting seat, a vertical rod, a fixing assembly, a measuring mechanism, a microprocessor and a wireless or wired communication module, wherein the bottom part of the lengthened measuring rod is directly or indirectly fixed on a bedrock layer; the embedded supporting seat is installed on a settlement layer; the vertical rod is inserted on the embedded supporting seat; the fixing assembly detachably and tightly connects the vertical rod and the embedded supporting seat; the measuring mechanism is used for measuring the relative displacement between the vertical rod and the lengthened measuring rod; the microprocessor is used for processing the data measured by the measuring mechanism; the wireless or wired communication module is used for remotely transmitting the data which are well processed by the microprocessor; the vertical rod has a hollow structure; and the upper end of the lengthened measuring rod is inserted in the vertical rod. The vertical rod and the embedded supporting seat are tightlyand firmly installed, the embedded supporting seat adopts embedded installation and is located at the inner side of the settlement layer, the settlement displacement of the settlement layer can be effectively reflected, and the measurement is efficient and accurate.

Description

technical field [0001] The invention relates to the technical field of soil layer settlement measurement, in particular to an integrated remote settlement observation station and an installation method thereof. Background technique [0002] In the alluvial plain of the Pearl River Delta, soft soil is distributed in a large area. Since the 1990s, a large number of engineering projects have been built in the Pearl River Delta region, and a considerable part of them have been damaged by geological disasters of soft soil land subsidence. Land subsidence disasters are becoming more and more serious, which not only affects the safety of industrial and civil buildings, but also affects the normal use of municipal infrastructure such as roads, bridges, underground power supply, gas supply, water supply and drainage pipe network, and water conservancy projects. [0003] Different from sudden geological disasters such as ground subsidence and landslides, although land subsidence geolo...

Problems solved by technology

[0007] Although the application of the magnetostrictive sensor is relatively mature, its ability to resist radio frequency interference and static Good, parallelism<±0.5mm, angle<±12°) and other characteristics will make the on-site installation more difficult, and its actual field use accuracy is difficult to meet the monitoring technical requirements;

[0008] Although the laser rangefinder is easy to install, the lens of the laser rangefinder needs to be cleaned regularly to avoid the influence of sediments on the measurement; the reflector or the surface of the target needs to be cleaned regularly. If there are sediments attached to it, it will affect the actual measurement Numerical value; Poor adaptability to rain, snow, fog and other environments will block the laser path and affect the actual measurement (all optical instruments are affected by this). At present, some experiments have proposed to use the pull-wire displacement meter to measure the settlement, but the current technology has some shortcomings, such as Installation is inconvenient, the cable is easy to tilt and cause errors, etc.
