Embodiment Construction
[0041] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0042] according to figure 1 As shown, the embodiment of the present invention provides a pipeline grouting device, which is characterized in that it includes: a grouting tank 7, a rolling device 5 and a support device 2, and the support devices 2 are set in multiples and spaced in a U shape It is arranged at the bottom of the grouting tank 7, and the two ends of the U-shape are set toward the opening direction of the grouting tank 7; Above; the grouting tank 7 is also provided with a grouting pipeline, the grouting pipeline is arranged between the support device 2 and the rolling device 5, and the two ends of the grouting pipeline protrude from the grouting tank 7 ...

The invention provides a pipeline grouting device. The pipeline grouting device comprises a grouting tank, a rolling device and a supporting device. The grouting tank is used for containing and a container of cooling water and controlling the temperature of resin materials which have been poured into a hose and are not evenly impregnated thoroughly. When the hose to be grouted is dragged to move forwards, the resin materials can be automatically immersed into a non-woven fabric structure of the hose. The rolling device is a hydraulic power lifting rolling roller, and the hydraulic power lifting rolling roller is a device which plays a role in exhausting and enhancing impregnation after all the resin materials are immersed into the non-woven fabric structure of the hose. The supporting device is used for guaranteeing that the grouting hose smoothly advances under the traction effect and does not rub with the bottom of the grouting tank. The invention further provides a construction method of the pipeline grouting device. The circumstance that a traditional CIPP technology cannot conduct low-temperature curing in a pipeline repairing process is avoided, the construction efficiency inthe pipeline repairing process is greatly improved, and the circumstances that curing fails due to the fact that the temperature does not reach the standard in the high-temperature curing operation process are reduced.
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 ...
