Cable probe rod reliability connecting rod device

Abstract

The invention discloses a cable probe rod reliability connecting rod device. The cable probe rod reliability connecting rod device comprises at least two probe rods, wherein the adjacent probe rods are sequentially hinged to form a chain-shaped structure, each probe rod comprises a first connecting part, a second connecting part and a third connecting part which are sequentially and fixedly connected along the same axis, a first limiting plane is arranged at the connecting part of the first connecting part and the second connecting part, a second limiting plane is arranged at the connecting part of the second connecting part and the third connecting part, the second limiting plane and the first limiting plane are opposite to each other, and a first positioning block is arranged on the outer circumferential surface of the first connecting part; and a plurality of first sliding grooves which are arranged in the circumferential direction of a sleeve and a plurality of second sliding grooves which are arranged along the axis of the sleeve are formed in the inner circumferential surface of the sleeve. The cable probe rod reliability connecting rod device is mainly used for underwater static sounding in-situ tests and can also be suitable for land static sounding in-situ tests.

Description

technical field [0001] The invention relates to the technical field of connecting rod structure of a cable probe rod, and specifically discloses a reliable connecting rod device of a cable probe rod. Background technique [0002] With the large-scale construction of marine resource development projects such as offshore wind energy utilization, tidal energy development, and oil and gas resource development, in order to ensure the safety and stability of offshore structures, it is necessary to determine the engineering properties of the foundation of offshore structures—marine soil. At the same time, in wading projects such as rivers and lakes, a large number of wading structures and underwater tunnel construction must also carry out underwater surveys to grasp the engineering properties of the bottom soil layers of rivers and lakes. The engineering property test of underwater foundation soil is a difficult problem in soil mechanics. After long-term geotechnical engineering p...

Problems solved by technology

This type of equipment has the following common characteristics: (1) The self-weight of the underwater working platform is often used as the reaction force system, and the self-weight of the underwater working platform is relatively large; The requirements are high; (3) artificial rods on the water are used. At the same time, during the installation of equipment and the penetration of the probe rod into the foundation, in order to prevent the probe rod above the foundation surface from breaking due to its own weight, currents, tides and waves, the underwater working platform A probe support tower whose height is the same as the penetration depth of the foundation is built above, resulting in a large overall size of the equipment and labor-intensive and time-consuming operation
