Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sediment sampling, especially relates to a water transport engineering sediment sampling device. BACKGROUND

[0002] Water transport engineering refers to infrastructure construction projects implemented in various water areas such as rivers, lakes, oceans, etc., aiming to provide key support for water transportation, logistics transportation, port management, channel maintenance, flood control and disaster reduction, and water environment protection, and is widely used in various scenarios, including port construction and expansion, channel dredging, wharf construction, flood control dams and revetment engineering, etc. These facilities collectively form an important transportation network in water areas.

[0003] Sediment sampling refers to the process of collecting sediment samples from the bottom of water bodies, and is commonly used in rivers, lakes, oceans, etc. to obtain true data of bottom sediments. Through sampling, the particle size, chemical composition, and pollutant content of underwater sediments can be analyzed in detail, revealing the geological structure, sedimentary environment, and pollution of water areas. This analysis result provides an important scientific basis for water transport engineering design, channel maintenance, dredging engineering, flood control measures, and water quality improvement.

Loose sediments will gradually be lost with the water flow under the action of water flow. This loss not only reduces the amount of collected samples, but also damages the hierarchical structure of sediments, affecting the integrity and representativeness of samples, and causing deviations in the final analysis results.
