Sludge tidal flat beach face elevation observer and application method thereof

Abstract

The invention discloses a sludge tidal flat beach face elevation observer and an application method thereof. A stainless steel pipe is inserted into a tidal flat, a concrete pier is formed by pouring below the tidal flat and on the root of a nylon rod, a bushing sleeves the nylon rod, the side wall of the bushing is fixedly provided with a hollow rod in which a connecting rod is inserted, the connecting rod is provided with a disc with eight circular holes which are distributed at equal intervals on the circumference with the connecting rod as the center, insertion needles on the bottom surface of a base are inserted into the circular holes of the disc, a hinge joint is fixed on the base, two opposite sides with the hinge joint as the center of the base are connected with a balance rod and a cantilever, respectively, and 18 holes, in which measuring needles are inserted, are distributed in the cantilever at equal intervals. The stainless steel pipe, the nylon rod, the bushing and the cantilever of the observer can be conveniently installed and transported, the settlement of the observer can be effectively prevented, and the measurement precision can be improved by adjusting the measurement direction and the measurement height and enlarging the measurement range.

Description

technical field [0001] The invention relates to the technical field of beach elevation measurement, in particular to a beach elevation meter and a method for using the same. Background technique [0002] my country is a country with a coastline of 18,000km. Climate change, sea level rise, large-scale planting of ricegrass on coastal tidal flats, reclamation of tidal flats, and human activities have all had a huge impact on the changes in tidal flats along the coast of my country. The process and prediction of tidal flat evolution are of great significance to the rational development, utilization and protection of coastal zones. The evolution of coastal tidal flats is also a topic of great concern to coastal engineering disciplines. The beach elevation measuring instrument is an important equipment for the study of coastal tidal flat profiles. [0003] The muddy tidal flat has a large tidal range, strong tidal effect, and violent tidal groove swing. On the smooth beach where ...

AI Technical Summary

Problems solved by technology

[0003] The muddy tidal flat has a large tidal range, strong tidal effect, and violent tidal groove swing. On the smooth beach where Spartina does not grow, the water flow disturbs the surrounding leveling piles violently. There will be local erosion around the pile. If the beach elevation observer of the US Geological Survey is used to measure the elevation change within 50cm around the leveling pile, the measurement error will be large

In addition, because there is a lot of silt on the muddy tidal flat, the trampling of the observer during the installation of the instrument may have an impact on the elevation of the tidal beach
