The invention provides a pipeline grouting device, comprising: a grouting tank, a rolling device and a supporting device, the grouting tank is used to hold and control the cooling water container of the temperature of the resin material that has been poured into the hose and has not been uniformly impregnated, When dragging the hose to be grouted to move forward, the resin material will be automatically immersed in the non-woven fabric structure of the hose; the rolling device is set as a hydraulic power lifting rolling roller, and the hydraulic power lifting rolling roller is After all the resin material is immersed in the non-woven structure of the hose, it plays a role of exhausting and strengthening the impregnation; the supporting device is used to ensure that the grouting hose advances smoothly under traction without friction with the bottom of the grouting tank; and provides A pipeline grouting device construction method, which realizes the situation that the traditional CIPP technology cannot be cured at low temperature during the pipeline repair process, greatly improves the construction efficiency during the pipeline repair process, and reduces the temperature failure caused by the high temperature curing operation. cause curing failure.
Description
technical field [0001] The invention relates to the technical field of underground pipeline repair, in particular to a pipeline grouting device and a construction method. Background technique [0002] The in-situ curing method, usually called the flipping method in China, refers to the non-excavation repair method of the sewer sewage channel, the original English text is Cured-in-Place Pipe. This repair method has little environmental pollution, little impact on traffic, does not disturb the people, and is low-carbon. It is the latest western technology introduced in China. The principle is to build a new pipe inside the original pipe, which has independent structural strength and can independently support external pressure and internal water pressure. The CIPP technology (NPT-CIPP) using room temperature curing materials has many advantages compared with heat curing and light curing technologies. For example, it avoids environmental pollution and potential safety hazards ...
