Problems solved by technology

[0002] Pipeline repair refers to the use of various technologies to restore damaged and leaking pipelines to normal use. Among them, the internal repair technology is relatively difficult, especially after a long period of use, the surface of the drainage pipeline is prone to various diseases, such as leakage. (concrete pipe), corrosion (cast iron pipe or steel corrugated pipe), the general in-situ repair technology is complex in construction and high in cost, and in some cases even higher than the cost of new pipes, providing a repair speed, low cost, surface compactness It is necessary to repair the pipeline by in-situ centrifugal spraying mortar with good water resistance and good wear resistance.

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0026] It should be understood that terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0027] Such as figure 1 As shown, the present invention provides a pipeline repair method in situ, comprising the following steps:

[0028] Step 1. Determine the section area of ​​the pipeline 100 to be repaired, then block one end of the pipeline 100 in the section area, and open the other end of the pipeline 100, clean up the debris in the pipeline 100, and then use high pressure The water gun cleans the inner surface layer of the pipeline 100 .

[0029] Step 2: laying a first layer of mortar layer on the corrosion area at the bottom of the pipeline 100 by means of grouting equ...

Abstract

The invention discloses a pipeline in-situ repairing method, which comprises the following steps: step 1, determining a to-be-repaired pipe section area of a pipeline, plugging one end of the pipeline in the pipe section area, opening the other end of the pipeline, cleaning impurities in the pipeline, and cleaning the surface layer in the pipeline by adopting a high-pressure water gun; step 2, laying a first mortar layer in a corrosion area at the bottom of the pipeline through grouting equipment; and step 3, spraying a second mortar layer to the interior of the whole pipeline in the repairing pipe section area through centrifugal spraying equipment, and completing pipeline repairing. The repairing speed is high, the manufacturing cost is low, and the repaired pipeline has good surface compactness, waterproofness and abrasion resistance.
