Disclosed is a sediment classification method and system based on bottom echo information of a deep-sea multibeam water column, falling within the technical field of seabed sediment classification. Multidimensional features of seabed multibeam time series are extracted by using multibeam water column data, and multidimensional features of seabed spots are constructed by fusing an angle response curve; double-waveform spectrum comparison of original sample point waveform with seabed measured point waveform is performed, and two groups of corresponding waveforms are matched by using Cosine Similarity to expand original sample points; and the reliability of classification results is improved. In the present disclosure, the transformation from hard to soft classification is realized, and the seabed habitat inversion of complex mixed sediment in a deep sea is further realized.

A fracturing pump spacer frame includes a hydraulic end connecting plate and a crosshead box connecting plate that are disposed spaced apart in parallel. The hydraulic end connecting plate and the crosshead box connecting plate are fastened by a support sleeve. The fracturing pump spacer frame further includes a leg. The hydraulic end connecting plate, the crosshead box connecting plate, the support sleeve, and the leg are integrally formed. The leg includes a first vertical supporting plate and a second vertical supporting plate that are vertically disposed and a first bottom supporting plate that is horizontally disposed. The first vertical supporting plate is located below the hydraulic end connecting plate. The second vertical supporting plate is located below the crosshead box connecting plate. Two sides of the first bottom supporting plate are respectively connected to lower ends of the first vertical supporting plate and the second vertical supporting plate. In the present disclosure, an integrally formed fracturing pump spacer frame is used, to avoid an impact of a welding defect on stiffness, strength, service life, and the like. An approximately U-shaped leg may support both a hydraulic end connecting plate and a crosshead box connecting plate, so that the number of support points is increased, a moment and a caused deformation are decreased, and service life is increased.
