Abstract

The invention provides an experimental device and method for repairing a pipeline by curing a soft lining material. The device comprises an old pipeline to be repaired; a fabric hose; the tractor can drag the fabric hose to move into the old pipeline; the walking trolley can walk in the pipeline and is provided with at least one heat sensor and at least one force sensor; the hot water and hot steam supplier is connected with the old pipeline through a pipeline so as to input hot water or hot steam into the fabric hose to cure the fabric hose; the control system can control the walking trolley to walk in the old pipeline and enter the fabric hose in the old pipeline in sequence, and the temperature and the mechanical property of the pipeline are detected in real time through the heat sensor and the force sensor. The device has the beneficial effects that pipeline repair experiments of various soft lining material curing methods can be simulated, and the temperature and mechanical properties of the pipeline are detected through the heat sensor and the force sensor in the experiment process.

Description

technical field [0001] The invention relates to the technical field of in-situ curing method (cipp) pipeline repair teaching demonstration, in particular to an experimental device and method for curing pipeline repair by soft lining material. Background technique [0002] After a long time of sewage erosion and rainwater erosion, the pipelines buried in the city's underground are easily ruptured, which will damage the lines inside the pipeline or cause sewage to seep out, and even lead to dangerous situations such as ground collapse. And due to the particularity of the city's geographical location, excavating and repairing the pipeline requires a lot of manpower and material resources, and will have an impact on urban life. Therefore, all parts of the world are currently using similar non-excavation soft lining material curing and repairing technology to repair pipelines in a planned way, and this type of technology is also booming in my country. [0003] In-situ curing met...
