A warning filler, its preparation method and its application in protecting buried pipelines

Abstract

The invention provides a warning filler, a preparation method thereof and an application in protecting buried pipelines. The components of the warning filler include basic dye, lime powder and water. The preparation method comprises the following steps: step 1, uniformly mixing basic dye, lime powder and water to obtain a mixture; step 2, drying the mixture naturally to obtain a warning filler. The application in the protection of buried pipelines includes the following steps: step 1, continuously laying the warning filler directly above the buried pipeline to form a filler layer; step 2, backfilling the covering soil directly above the filler layer, restoring the landform until the excavation previous state. Low cost, convenient on-site construction, and can play a warning role for buried pipelines.

Description

Technical field [0001] The present invention relates to the field of pipeline protection, and more particularly to a warning filler and a preparation method thereof and an application in protecting a buried conduit. Background technique [0002] The buried pipe is used as a transport carrier of the oil and gas, which is a link between the upstream resources and downstream users. Since the pipeline is buried in the ground, there is a man-destroying, mechanical excavation, etc., leakage, not only brings serious economic losses, but also causes the harmful substance to cause pollution, and even cause Sudden disaster accidents, endanger personal safety. [0003] A variety of ground marks above the pipeline, including marking piles, identification bands, and warnings, etc. These facilities have supported a safe operation of pipeline safety operations. However, since these tags are mounted on the ground, these markers are in human, or external for external force without existence as th...

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
