The application discloses a deep-buried pipeline positioning method and system based on magnetic gradient values and belongs to the technical field of underground pipeline detection. The method comprises the following steps: calculating an effective magnetization inclination; obtaining an observation curve of a vertical magnetic gradient sequence in a single-hole measuring well adjacent to a target pipeline, extracting an extreme point depth value and calculating an extreme value distance; calculating an absolute value of a horizontal lateral distance between the target pipeline and the single-hole measuring well; generating a theoretical curve according to the absolute value and a preset initial depth, comparing the theoretical curve with a shape feature of the observation curve, determining a horizontal position and determining a positive or negative symbol of the horizontal lateral distance; and finally, according to the signed horizontal lateral distance, the extreme point depth value and a dimensionless parameter, the accurate burial depth of the target pipeline is inversely calculated. The application can directly analyze the spatial position parameters of the pipeline only by using single-hole data, effectively overcomes the multi-solution problem of inversion, significantly reduces the engineering cost and improves the detection accuracy.

This utility model relates to the technical field of geogrid splicing tools, specifically, to a rapid splicing and connection device for geogrids. It includes multiple geogrid bodies, each with multiple exposed holes. Multiple splicing and fixing components are provided between adjacent geogrid bodies. Each splicing and fixing component includes a first insertion rod and a second insertion rod inserted through the corresponding exposed hole. An insertion cone is fixedly installed at the bottom end of both the first and second insertion rods. A color marking plate is fixedly installed on the top of both the first and second insertion rods. An upper force-bearing plate is fixedly installed at the top of both the first and second insertion rods. A horizontally positioned horizontal column is fixedly installed on the top of the first insertion rod. The second insertion rod is sleeved on the horizontal column and slidably connected to it. This utility model facilitates rapid splicing and connection operations, is simple to operate, and convenient to use.

This invention discloses a method for automatically generating structured meshes and terrain for canals based on parametric modeling. This method involves parametrically inputting canal design parameters and original terrain data, and sequentially executing five core steps: original terrain interpolation and fusion, generation of straight channel meshes and terrain, generation of curved channel meshes and terrain, seamless stitching of straight and curved meshes with terrain, and mesh-terrain format conversion and structured reconstruction. The entire process is automated using MATLAB code. This invention addresses the pain points of existing technologies, such as distortion in straight-curved stitching, low automation, and poor digital twin adaptability. The generated structured mesh is accurately adapted to the 3D terrain and can be directly imported into numerical simulation software and digital twin platforms. It provides high-precision data support for canal engineering design, hydraulic characteristic analysis, and digital twin system construction, and is suitable for engineering needs involving multiple sections of alternating straight and curved artificial canals.
