Aiming at particularity of the case of using freezing method to conduct shaft-forming well wall restoration project

at the same time of monitoring the conventional hydrological hole and thermometer hole

new means of detection are added

and distributed fiber temperature detection technology is used to check the temperature of each longitudinal freezer. By data analysis

provide basis for guiding the freeze construction being carried out safely and smoothly. The general situation of restoration project

the principle

composition

detection method and temperature measuring optical cable structure of the distributed fiber temperature detection system are introduced in detail. Field measured data is given

which has large quantities of datas and can reflect the actual development status of freezing wall comprehensively and intuitively compared with the traditional thermometer hole data. System structure is simple and flexible

also the detection method has certain promotional value.
