Abstract

The invention discloses light seabed type cone penetration test operation equipment. The equipment comprises an operation platform arranged on an operation sea surface and further comprises a gantry fixing assembly, a lifting assembly, a compensation assembly, a pressurizing assembly, a suction anchor assembly and a probe rod, wherein the gantry fixing assembly is fixedly arranged on the working platform; the lifting assembly is fixedly arranged on the gantry fixing assembly and can move up and down; the compensation assembly is fixedly arranged on the operation platform and used for compensating displacement of the lifting assembly and tension needed by the probe rod in the moving process; the pressurizing assembly is fixedly connected with the lifting assembly through the probe rod and used for driving the probe rod to be pressed down or pulled up; the suction anchor assembly is fixedly connected with the pressurizing assembly and is used for penetrating into the seabed by adsorption or being ejected out of the seabed by pressurizing; and a cone penetration test probe is arranged at the top end of the probe rod. According to the invention, the characteristic of good pulling resistance of a light suction anchor is utilized, a heavy base of a heavy seabed type CPT is replaced, and the purpose that a light structure meets the requirement of CPT operation of heavy CPT driving penetration is achieved.

Description

technical field [0001] The invention relates to the technical field of ocean detection, in particular to a light-duty seabed-type static sounding operation equipment. Background technique [0002] The construction of offshore wind farms requires a detailed understanding of the soil characteristics of each soil layer on the seabed in the project area, obtaining engineering property indicators for each soil layer, and determining pile foundation parameters, etc. Seabed static penetrating sounding system is an important means of seabed soil mechanics survey, which has the advantages of fast and accurate. [0003] At present, the domestic wind power market is developing rapidly. According to the current wind power projects, the water depth is generally within 40m, and the bottom is soft clay. Taking advantage of the good pull-out performance of the suction anchor, the suction anchor foundation has good working performance in the muddy soft clay. , has been successfully applied ...
