Warning filler, preparation method thereof and application of warning filler in protecting buried pipeline

Abstract

The invention provides a warning filler, a preparation method thereof and an application of the warning filler in protecting buried pipelines. The warning filler comprises the following components: basic dye, lime powder and water. The preparation method comprises the following steps: step 1, uniformly mixing the basic dye, the lime powder and the water to obtain a mixture; and 2, naturally airingthe mixture to obtain the warning filler. The application of the warning filler in protection of the buried pipeline comprises the following steps: 1) continuously laying the warning filler over theburied pipeline to form a filler layer; and step 2, backfilling and earthing right above the filler layer, and recovering the landform to the state before excavation. The cost is low, field construction is facilitated, and the warning effect on the buried pipeline can be achieved.

Description

technical field [0001] The invention relates to the technical field of pipeline protection, in particular to a warning filler, a preparation method thereof and an application in protecting buried pipelines. Background technique [0002] As the carrier of oil and gas, buried pipelines are the link connecting upstream resources and downstream users. Since the pipeline has been buried underground for a long time, there are accidents of pipeline perforation and leakage caused by man-made damage, mechanical excavation, etc., which will not only bring serious economic losses, but also cause leakage of harmful substances, pollute the environment, and even cause Sudden disasters and accidents endanger personal safety. [0003] In SY / T 6064-2011 "Technical Specifications for Marking of Main Lines of Pipelines", various ground markings above the pipelines are proposed, including facilities such as marking piles, marking tapes and warning signs. These facilities have played a certain...

Problems solved by technology

This technology includes: using bearing steel and reinforced concrete slabs as protection measures for buried pipelines, which is time-consuming and labor-intensive during installation, which is not conducive to on-site construction; there is also the use of directly wrapping mesh plastic nets on the outer wall of the pipeline, It can only prevent small impact on the pipeline during backfilling. Once the plastic mesh is damaged, the stress source will directly act on the pipeline, and it cannot play an early warning role

[0004] The implementation of pipeline marking on the ground has the problems of easy damage and not long-term preservation, while the use of underground laying protection facilities increases investment costs and there will be errors or untimely signal feedback, which cannot clearly prompt the information of the underlying pipeline, which increases further damage pipeline risk

At present, there is a method of pouring liquid dyes into the protection boards for protection, but this method needs to arrange the protection boards and add dyes on site, which has the problem of inconvenient construction
