Installation method of dam internal temperature monitoring system

Abstract

The invention provides an installation method of a dam internal temperature monitoring system. Fibers of fiber induction meters are braided on geotechnical gratings to form a network structure of the fiber; the geotechnical gratings braided with the fibers of the fiber induction meters are laid in a dam to form a temperature sensor; one data acquisition box is used for receiving, storing and analyzing data acquired by the temperature sensor. The method can realize full-life long-term real-time monitoring of the internal temperature of the dam from a construction phase to an operation phase, can overcome many defects and restrictions existing in a conventional manual detection mode in the prior art and has the advantages of accuracy, stability, high effectiveness, timeliness and long-term performance. The fiber induction meters are combined with the geotechnical gratings so that it is ensured that distribution of the fiber induction meters accords with application needs while the fibers are protected.

Description

technical field [0001] The invention relates to the field of temperature monitoring inside a dam, in particular to an installation method of a real-time temperature monitoring system inside a dam based on optical fiber sensing technology. Background technique [0002] With the development of our country's economy, especially the current acceleration of urbanization, many small towns are developing better and better, and the requirements for embankments along the river and along the river are getting higher and higher. Although in recent years, my country has gradually promoted measures such as reinforcement of dykes along the river, there are still some weak links, especially after heavy rains in a short period of time, there will still be serious disasters such as piping and even collapse of some dams . How to monitor the dikes and dams is one of the problems to be solved urgently. [0003] Traditionally, manual monitoring is mostly used for the monitoring of dams, and mos...

AI Technical Summary

Problems solved by technology

[0003] Traditionally, manual monitoring is mostly used for the monitoring of dams, and most of the methods are regular or irregular monitoring. This method is not only inefficient, but also difficult to meet the requirements

As far as the existing monitoring methods are concerned, the water content and stability monitoring of the embankment cannot respond in real time, and it is often discovered that serious damage occurs

The traditional method cannot know the status of the dam in real time, which has caused serious disasters such as water seepage or even collapse of the dam, which does not meet the requirements of modern scientific management
