摘要： A method and apparatus for performing maintenance on sewer pipes using a thermal sensor. The method and apparatus may be applied to the reinstatement of lateral openings after a liner has been installed in a main pipe. The thermal sensor detects the location of the lateral openings by sensing the thermal conditions of the liner. The thermal condition of the portions of the liner that cover the lateral openings is different from the thermal condition of the rest of the liner. The apparatus and method is also applicable to detecting groundwater leaks in the main pipe, and is also applicable to inspecting exothermic chemical reactions in the main pipe, such as exothermic grout or epoxy used to seal the liner in the main pipe. The thermal sensor may be integrated into a camera assembly that includes a visual camera at one end and the thermal sensor at the other end. The visual camera is useful in those portions of the main pipe that are full of water.

摘要翻译： 一种使用热传感器对下水管进行维护的方法和装置。 在将衬套安装在主管中之后，该方法和装置可以应用于侧开口的恢复。 热传感器通过感测衬套的热条件来检测侧向开口的位置。 覆盖侧面开口的衬套部分的热状态不同于衬套的其余部分的热条件。 该设备和方法也适用于检测主管中的地下水泄漏，也可用于检查主管中的放热化学反应，如用于密封主管内衬的放热灌浆或环氧树脂。 热传感器可以集成到相机组件中，该相机组件包括一端的视觉相机和另一端的热传感器。 视觉摄像机在主管的那些充满水的部分是有用的。
