Dam leakage monitoring fiber optic cable

大坝渗漏监测光缆
 Dam Leakage Detecting Senor Cable
产品描述 Description
大坝渗漏监测传感光缆是一种专门用来监测大坝坝体的细微渗漏及大坝健康状况的一种传感光缆。这种光缆采用内置电加热丝的独特设计。在大坝建造时，将监测光缆与布设于大坝的的钢筑龙骨之上，在混凝土浇注时，作为测温光缆监测坝体的混凝土凝固的温度状态，提高混凝土的质量。在大坝运行阶段，不定时地对光缆进行加热，通过热差值来监控大坝的渗漏点，从而早发现问题，避免重大事故发生。
  Dam Leakage Detecting Senor Cable is a kind of sensor cable specially used to monitor the slight leakage and the health of the dam. This optical fiber cable adopts the unique design of the built-in electric heating wire. At the time of the dam construction, we install the sensor cable on the steel building keel of the dam. During the concrete pouring, the cable acts as a DTS sensor cable to monitor the temperature condition of concrete solidification of dam body. During the operation of the dam, the cable is periodically heated and the leakage point of the dam is monitored by the thermal difference, in this way, we will find the leakage of dam, which avoids certain accidence.
