Monitoring device and monitoring method for pipeline landslide-anti-slide pile structure combination

Abstract

The invention discloses a monitoring device and a monitoring method for pipeline landslide-anti-slide pile structure combination, and the device comprises a landslide deep displacement monitoring device, a landslide surface displacement monitoring device, a landslide-to-pipeline thrust monitoring device, a pipeline body monitoring device, an anti-slide pile structure monitoring device, a landslide environment parameter monitoring device, and an on-site monitoring station. The fiber bragg grating sensing technology is applied to system monitoring of the pipeline landslide, system monitoring of the pipeline landslide is achieved through the fiber bragg grating sensing technology, and compared with a traditional monitoring mode, automatic real-time monitoring is easy to achieve, the spatial resolution is high, and cost is low; the invention provides a combined monitoring method for a landslide-pipeline-slide-resistant pile structure, and the characteristic of interaction of the landslide, the pipeline and the slide-resistant pile structure is revealed; the monitoring system is easy to construct, real-time automatic acquisition and analysis and remote release of monitoring data and real-time automatic alarm are easy to realize, and the monitoring system is of great importance to the adoption of pipeline emergency measures.

Description

technical field [0001] The invention relates to a pipeline landslide monitoring device, in particular to a monitoring device and a monitoring method for the combination of a pipeline landslide-anti-slide pile structure, and belongs to the technical field of stress strain and displacement measurement and pipeline systems. Background technique [0002] As one of the important lifeline projects of the country, the safety of oil and gas pipelines has become an important link related to the lifeline of the entire country's economy. Once a safety problem occurs, its social harm and attention are extremely high. More than 75% of my country's active oil and gas pipelines are buried in complex geological environments such as mountainous areas and permafrost areas. Due to the lack of sufficient argumentation or the inevitable passage through some areas with active geological structures, these areas are often geological disasters. Especially in areas where landslide disasters occur freq...

Problems solved by technology

[0003] Under the circumstances that the pipeline will inevitably pass through many areas with severe geological disasters and face many pipeline landslide disasters, although the companies engaged in pipeline operation in my country have taken many corresponding engineering control and protection measures, the field environment is harsh and changeable. Under the long-term soil stress of the slope, the retaining structure materials will also be damaged and cracked, which poses a great threat to the stability of the slope, and at the same time seriously threatens the safe operation of the pipeline. Traditional monitoring methods are often limited For joint monitoring of pipelines or landslides or both, it is rare to monitor the safety of slope protection structures at the same time. A Chinese invention patent published on August 3, 2011 with the publication number CN101667327B "Pipeline Landslide Deep Displacement Monitoring and Early Warning Method and System and the construction method of the system”, which realizes the early warning of pipeline landslides through the monitoring of the deep displacement of the pipeline landslide, the monitoring of the thrust of the landslide on the pipeline, and the monitoring of the strain of the pipeline, but it does not involve the monitoring of landslide resistance and the monitoring of the pipeline environment
