Description

Technical Field

[0001] The invention belongs to the technical field of static penetration sounding, and in particular relates to a seabed chain clamping driven continuous penetration static penetration sounding device. Background Art

[0002] Static penetration testing involves using static force to press a probe into the soil at a constant rate. Using a force sensor within the probe, electronic measuring instruments record the penetration resistance experienced by the probe, revealing the characteristics of the soil at different layers. It is primarily used to delineate soil layers, determine the engineering properties of each layer, and determine foundation soil parameters. Compared to seabed sampling and analysis methods, seabed static penetration testing offers the advantages of speed and accuracy, making it a crucial tool for seabed engineering soil mechanics investigations. Three well-established construction techniques exist for conducting static penetration testing in marine environments: platform-based, seabed-based, and underground. The main feature of the platform-type penetration test is that the penetration equipment is installed on a fixed platform. During the penetration test, the probe must first pass through the water layer from the platform deck before penetrating into the seabed formation. The main feature of the seabed-type penetration test is that the penetration equipment is stably supported on the seabed surface, and the probe is directly and continuously penetrated into the seabed to obtain the formation stress detected by the probe. The main feature of the downhole-type penetration test is a cyclic penetration method that combines drilling and static penetration. During the penetration test, the penetration device is installed inside the drill pipe and the probe is penetrated from the bottom of the drill pipe through the drill bit into the seabed formation. The drilling is mainly responsible for clearing the formation where the penetration has been completed in order to start the next penetration test cycle. In a comprehensive comparison, the seabed static penetration test has obvious advantages in both technical and construction aspects. The main features are: it can be used in both shallow and deep water, with a wide range of applications; the penetration base is stable and the penetration path is continuous; it can adapt to different detection depth requirements by different penetration force, deadweight and casing configurations; it is easy to construct, the construction cost is low, and the construction efficiency is high. Therefore, seabed static penetration is currently the most widely used marine static penetration construction technology in the world, and its related equipment is also the most diverse.

[0003] Currently, foreign companies engaged in the research, development, production, and sale of seabed CPS systems include Fugro of the Netherlands, Vandenberg of the Netherlands, and Datem of the UK. These companies' products handle over 80% of my country's marine CPS workload, but these products are imported, expensive, and subject to confidentiality. Therefore, my country urgently needs cost-effective, high-end seabed survey equipment for various marine engineering projects to accurately determine the seabed's geological conditions and specific physical and mechanical parameters. Seabed CPS development in China started relatively late, primarily with the successful development of the seabed CPS instrument by the Institute of Oceanology, Chinese Academy of Sciences, in the 1970s. Subsequently, a number of seabed CPS systems adapted to various underwater conditions were developed. However, these systems have not seen the widespread adoption seen abroad, remaining at the research level. Actual applications are limited, particularly for CPS systems with higher penetration forces. Summary of the Invention
