Detection method of penetration performance of plant root system to pipeline anticorrosion layer

Abstract

The invention discloses a method for detecting the performance of plant roots on penetrating a pipeline anticorrosion layer, and belongs to the field of pipeline anticorrosion. The method comprises the following steps: picking a target plant, digging a trench in an area, wherein the distance between the area and the trunk of the target plant is 0.8 to 1.3 m, exposing the plant roots in the trench;arranging a vertical wall in the trench; paving a pipeline anticorrosion layer on the lateral surface, which faces the target plant, of the wall; then paving at least one minirhizotron on the pipeline anticorrosion layer, wherein the lower opening of the minirhizotron is arranged on the bottom of the trench, and the upper opening of the minirhizotron is arranged on the opening of the trench; backfilling the trench, making the roots grow in a predetermined period, periodically inserting a linear scanning head of a minirhizotron root ecology monitoring system into the minirhizotron to carry outscanning so as to obtain scanning images; and utilizing a root analyzer to analyze the scanning images to obtain parameter information that represents the root morphologic change so as to determine the penetrating performance of the plant roots on the pipeline anticorrosion layer. The method is convenient to perform, and the data is reliable and easy to extract.

Description

technical field [0001] The invention relates to the field of pipeline anticorrosion, in particular to a method for detecting the penetration performance of a plant root system to a pipeline anticorrosion layer. Background technique [0002] With the continuous expansion of the scale of pipeline construction in my country, contradictions inevitably arise between pipeline laying and planting along the line. When the pipeline is applied, it is necessary to coat the outer wall with an anti-corrosion layer. By studying the influence of deep-rooted plant roots on the pipeline anti-corrosion layer, especially the penetration performance of the pipeline anti-corrosion layer, it is possible to accurately evaluate the damage of the plant root system to the pipeline. This is of great significance for protecting the safety of pipelines, reducing the burden of pipeline construction, and protecting local economies and resources. Since the plant root system grows in the soil "black box" m...
