Saturation device for spherical static sounding probe and saturation method

Abstract

The invention relates to the related technical field of marine new energy engineering and marine geotechnical investigation in-situ test, in particular to a saturation device for a spherical static sounding probe and a saturation method. An upper cavity and a lower cavity can be separated up and down and are matched in a staggered mode through a first step part and a second step part, sealing between the upper cavity and the lower cavity can be effectively formed, a hard breathable plate with a fixing hole can be placed on the first step part, the circumference of the hard breathable plate isfixed through the side wall of the upper cavity and the first step part of the lower cavity, and the bottom of the spherical static sounding probe is effectively fixed through the bottom plate with the concave surface in the lower cavity; and the bottom of the spherical static sounding probe is fixed in the lower cavity through the hard breathable plate and the bottom plate with the concave surface in the lower cavity, and the problem that the spherical static sounding probe shakes left and right or slides due to shaking of a working platform under the offshore stormy wave condition is effectively solved.

Description

technical field [0001] The invention relates to the related technical fields of marine new energy engineering and in-situ testing of marine geotechnical survey, in particular to a saturation device and a saturation method for a spherical static penetration probe. Background technique [0002] Ball penetration test (Ball penetration) is an in-situ test method for soft clay. Its operation method is similar to traditional pore pressure static penetration test (CPTU), the difference is that the probe is spherical and the pore pressure The sensor is located in the middle of the spherical probe; during the penetration process, the surrounding soil is in a full flow state (full flow), and the test process is less affected by the overlying pressure. At the same time, through continuous penetration and uplift, soft clay can be quickly measured Reshape strength and get soft clay sensitivity. [0003] Since the spherical static penetration probe is similar to the traditional pore pres...

AI Technical Summary

Problems solved by technology

The traditional pore pressure static penetration probe has a corresponding saturation device. When the traditional pore pressure static penetration probe saturation device is used to saturate the spherical static penetration probe, it is found that the spherical static penetration probe is circular, especially for offshore operations. When the operation platform shakes due to the influence of wind, waves and currents at sea, it is impossible to effectively saturate the probe.
