Process and device for installing an ultra-deep underwater suction caisson foundation

The application discloses a process and device for an ultra-deep underwater suction bucket foundation, and belongs to the technical field of sinking and installing a large offshore floating platform; a support beam is fixed to a side deck; a hoisting beam is connected with a connector A, the connector A is connected with a suction bucket, and the hoisting beam is connected with a lifting hook; a crane hoists and sidely hoists into water; the crane is adjusted to hang the connector A in the support beam and continue to sink until all the weight is transferred; the connector A is removed from the hoisting beam, the connector B is connected with the hoisting beam and connected with the connector A; the crane is adjusted to separate the connector A from the support beam, so that the suction bucket continues to sink after all the weight is transferred to the crane; the above steps are repeated to continuously connect the connector B and a lifting cable C until the suction bucket is sunk into mud; the lifting cable B is removed after the sinking of the suction bucket is completed; the load is temporarily transferred by means of the deck of a construction ship through the series connection of the connection structure, the selectivity of construction resources is greatly widened, the working cost is reduced, and time is saved.

Deeply buried pipeline positioning method and system based on magnetic gradient value

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.

A method for automatic generation of structured meshes and terrain in canals based on parametric modeling

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.
