Example 1.
As shown in fig. 1-6, the invention relates to a slip form system for repairing an in-service pipeline with water, which is used for repairing the in-service pipeline with water, and comprises a plurality of groups of repairing modules 2, wherein the groups of repairing modules are sequentially laid in the pipeline along the extending direction of the pipeline; each fixing component 1 is connected with the repairing module and used for fixing the repairing module 2, and a repairing gap d is formed between the repairing module 2 and the inner side wall of the pipeline to be repaired; the sliding rail 4 is positioned in the pipeline to be repaired, is connected with one side, away from the pipeline, of the repair module 2 in a sliding mode, and is used for conveying a plurality of groups of repair modules 2; the plugging plates 3 are arranged at two ends of the pipeline to be repaired and fixedly connected with the repairing modules 2 at the two ends of the pipeline to form a repairing station 2-d for filling repairing materials.
In the working process, a sliding rail 4 is laid on the inner top wall of a pipeline to be repaired, then the repairing modules 2 are integrally spliced in an observation well in sequence and hung on the sliding rail 4, each repairing module 2 is pulled through external traction equipment, so that the length of each spliced repairing module 2 is consistent with the length of the pipeline to be repaired, each repairing module 2 is fixedly connected with the pipeline to be repaired through a fixing component 1, plugging plates 3 are installed at two ends of the repaired pipeline to form a repairing station 2-d, it is required to be noted that when the plugging plates 3 are installed, the plugging plates 3 at the upstream end of a water source are installed firstly to realize the cutoff of the water source, and when sewage at the repairing station 2-d flows out, the plugging plates 3 at the downstream end of the water source are installed, so that the sewage in the pipeline cannot flow into the repairing station 2-d, the sewage flows in a sewage discharge pipe formed on one side of the inner side wall of the pipeline to be repaired, from the repairing module 2, the repairing materials are conveyed to the repairing stations 2-d through external conveying equipment, and after the repairing materials are filled in the repairing stations 2-d, the conveying is stopped, so that the repairing operation of the pipeline to be repaired is completed.
