Ultraviolet light solidification soft pipe lining old pipeline repairing technology

Abstract

The invention relates to a non-excavation-repairing technical field of old pipelines, in particular to an ultraviolet light solidification soft pipe lining old pipeline repairing technology. The ultraviolet light solidification soft pipe lining old pipeline repairing technology comprises the following steps that a, an on-the-spot investigation is conducted; b, glass fiber lining soft pipe semi-finished products are manufactured in a workshop, wherein glass fiber lining soft pipe semi-finished products in the workshop comprises the steps of manufacturing fiber soft pipes, preparing light-curing resin and manufacturing lining soft pipe semi-finished products; c, on-the-spot lining construction is conducted. Preparation in the workshop and formation on the spot are adopted in the ultraviolet light solidification soft pipe lining old pipeline repairing technology.

Description

technical field [0001] The invention relates to the technical field of non-excavation repair of old pipelines, in particular to a process for repairing old pipelines with ultraviolet curing hose linings. Background technique [0002] The current old pipeline repair methods include cement mortar extrusion coating method, CIPP lining method, HDPE pipe interspersed lining method, stainless steel lining method, etc. The CIPP lining method is the most widely used and more convenient and effective method. The materials used are polyester fiber felt and ordinary resin, which are cured by heating, but there are also some problems: 1. The curing cannot be well controlled. Time, once it fails, both direct and indirect costs will cause huge waste; 2. CIPP lining needs to be prepared with ingredients and impregnated with resin, which increases the workload and preparation time of the construction site, increases the risk of failure, and occupies roads. 3. The combination of polyester f...

Problems solved by technology

The CIPP lining method is the most widely used and more convenient and effective method. The materials used are polyester fiber felt and ordinary resin, which are cured by heating, but there are also some problems: 1. The curing cannot be well controlled. Time, once it fails, both direct and indirect costs will cause huge waste; 2. CIPP lining needs to be prepared with ingredients and impregnated with resin, which increases the workload and preparation time of the construction site, increases the risk of failure, and occupies roads. 3. The combination of polyester fiber and resin and its own strength make the performance of the inner lining layer formed after curing poor, and the inner lining layer often has insufficient pressure bearing capacity. The inner liner collapse, bulge, and rupture accidents often need to increase the thickness of the inner liner
