Ship-based portable deep-sea seabed soil field strength testing device

Abstract

The invention discloses a ship-based portable deep-sea seabed soil field strength testing device, belonging to the achievement work of the deep-sea seabed soil mechanical property testing technology and device in the field of marine engineering, geotechnical engineering and geological engineering, due to the fact that the test site is located on the field test or engineering ship, and the technical device overcomes the obstacles of the deep sea in time and space, a field test result with certain timeliness can be obtained. According to the device in the invention, a sensor is arranged on the top of a probe to avoid the distortion caused by temperature difference or humidity difference of the sensor; a sample is fixed by using a telescopic arm lock, so that the sample is not affected by thesway of a hull during the test; automatic control of one-time penetration or loop penetration is realized by computer programming, which is more efficient and accurate; the optimized data acquisitionsystem is adopted so as to ensure the stability and reliability of the acquired data; and the optimized computer data analysis software is adopted so as to ensure the integrity of the data and realize fast, accurate and efficient data processing.

Description

technical field [0001] The present invention belongs to the field of marine engineering, geotechnical engineering and geological engineering, and is an inventive achievement aimed at testing the mechanical properties of deep-sea seabed soil and its device. Since the test site is located on a field experiment or an engineering ship, and the technical device overcomes the problem of deep-sea seabed soil mechanical properties testing technology and device Due to the obstacles of time and space, it can obtain field test results with certain timeliness, so it is named as the ship-based portable deep-sea seabed soil field strength test device. Background technique [0002] my country is both a land power and a sea power, possessing abundant marine resources. It is of great significance to obtain the strength test research results of seabed sediments, especially deep and open sea seabed soils, for the design and stability evaluation of marine engineering structures. At present, th...

Problems solved by technology

Most of the above experimental studies were only established in the indoor laboratory environment, relying only on the indoor test of the full-flow penetrometer to explore the properties of seabed sediments, but the disturbance of the samples during the collection and packaging and transport back to the laboratory was ignored , which inevitably affects the accuracy of the test results
