Description
Technical Field
The utility model relates to a cement drain pipe antiseep restoration PE 100-grade modified round concave circular lining pipe which is formed by pressing a PE pipe from a circular shape into a concave shape and then changing air recharging into a circular shape, belonging to the technical field of underground culvert pipe lining pipelines.
Background
The underground culvert pipe for urban drainage and pollution discharge is usually a cement pipe, and along with the increase of service years, under the action of interference factors such as corrosion of underground water in the pipeline, pipeline running load, geographical settlement, underground engineering and the like, the joint of the cement pipe is cracked or the pipeline is damaged and leaked, so that the conveying function of the culvert pipe is lost, and the leakage water can cause soil loss to cause road surface collapse. At present, the commonly used maintenance method for the damaged culvert pipe is to spray repair glue or weld the leakage point, so that the culvert pipe with longer service life can only be maintained for a short time, and the problem of damaged leakage cannot be thoroughly solved.
In order to solve the problems, a new method is provided for the maintenance of the culvert pipe in the prior art, namely, a PE pipe with certain plasticity is lined in the culvert pipe, so that the service life of the culvert pipe is prolonged, and the corrosion resistance of the culvert pipe is enhanced; but because culvert pipe inner wall unevenness and the culvert pipe distance between two wellheads is longer, the degree of difficulty is great when drawing the entering culvert pipe for circular PE pipe, and PE pipe is stopped up when the PE pipe often can appear getting into culvert pipe half or two-thirds the position, can't continue to pull, leads to the engineering can't continue to go on, only must take the method of digging underground culvert pipe, not only wastes time and energy, can greatly increased engineering cost moreover. Therefore, when the method is adopted, the diameter of the lining PE pipe is made to be much smaller than the inner diameter of the culvert pipe, so that a large gap is reserved between the outer surface of the lining pipe and the inner wall of the culvert pipe, the gap is not less than 20 cm generally, and thus, although the difficulty of pulling the lining pipe into the culvert pipe is solved, the PE pipe can be deformed in an arc shape with a low middle and two high ends under the conditions of self weight, sewage in the pipe and collapse due to the certain flexibility of the PE pipe, the PE pipe can be deformed in an arc shape with two low ends and two high ends, so that the PE pipe orifices at two ends are deviated to the middle, and the problem of pipeline leakage can not be thoroughly solved due to the fact that the sewage flows between the outer surface of the lining pipe and the inner wall of the culvert pipe due to the crack of the PE pipe orifices and the culvert pipe orifices; meanwhile, the sewage is retained in the middle of the lining PE pipe, which also causes the lining pipe to fail to work normally, and therefore, it is necessary to improve the sewage.
