Abstract

The invention discloses a seabed multi-point static sounding device. The seabed multi-point static sounding device comprises an underwater heaving moving unit, a CPTu feeler lever assembly and a hydraulic propelling system, wherein the underwater heaving moving unit comprises a supporting frame, a guide frame and boat-type buoys, the guide frame is vertically fixed to the supporting frame, and the boat-type buoys are symmetrically arranged on the guide frame and used for providing heaving force; the CPTu feeler lever assembly is installed on the supporting frame and guided by the guide frame; and the hydraulic propelling system is used for providing penetration force for the CPTu feeler lever assembly. The CPTu sounding device can work at the seabed depth of 100m, the static penetration depth of a feeler lever can reach 30m, a detection station is autonomously and flexibly selected through an underwater heaving moving platform and in cooperation with a small floating tugboat on water, and testing of the soil mechanical property of seabed surface sediments of the station is completed.

Description

Technical field[0001]The present invention belongs to the field of marine observation, and the seawatum of marine engineering is related to the seabed multi-site static touch equipment.Background technique[0002]my country's large-scale major infrastructure in China, such as sea wind power, sea oil and gas platform, marine pasture platform, etc.), the subserving founder is its ultimate carrier. In the ocean extreme environment load (such as typhoon, huge waves, etc.), the sea structure is collapsed or excessively tilted, resulting in conventional design redundancy. Safety, the economy of sea and labor structure is mainly dependent on high efficiency survey and scientific analysis of mechanical properties of seabed. At present, the largest sequenial survey equipment (mainly static touch instrument CPTU and its penetration equipment) The maximum working water depth and penetration detection depth cannot meet all depth of work needs in my country, and generally more single-point Fixed s...
