Problems solved by technology

This type of equipment has a common feature: the underwater working platform is very heavy, and the self-weight of the underwater working platform is often used as the reaction force system. When launching on the ship, the lifting equipment on the ship is highly required; During the foundation process, the rods are manually connected on the ship. In order to prevent the probe rods above the foundation surface from breaking under the action of self-weight, water flow, tides and waves, a probe rod support tower with the same height as the water depth is often built on the underwater working platform. A labor-intensive and dangerous job

Abstract

The invention provides an automatic rod connecting system for cable probing rods. The automatic rod connecting system for the cable probing rods includes a static penetration probe, a cable probing rod, an equilateral-polygon-shaped cylindrical capstan, a capstan roller screw rod, a support, a hydraulic motor, a rod connecting or folding converter and a data collector. The cable probing rod is formed by connecting a plurality of probing rod units in a hinged mode in sequence, and can wind round the equilateral-polygon-shaped cylindrical capstan at a certain inclination angle. The capstan roller screw rod is supported by the support and driven by the hydraulic motor, and when the hydraulic motor drives the equilateral-polygon-shaped cylindrical capstan to rotate, the capstan roller screw rod drives the equilateral-polygon-shaped cylindrical capstan to move in the axial direction of the capstan roller screw rod so as to assure that the cable probing rod passes through the rod connecting or folding converter in a fixed position in the rotation process of the equilateral-polygon-shaped cylindrical capstan. The static penetration probe is connected with the data collector through a data acquisition cable. The automatic rod connecting system has the advantages of being stable in performance, simple in operation and low in system cost, and can greatly improve the in-situ testing speed of underwater geotechnical engineering and reduce the test cost of underwater in-situ testing.

Description

technical field [0001] The invention relates to the technical field of in-situ testing of geotechnical engineering, in particular to an automatic connecting rod system for a cable probe rod and a static penetrating sounding test method. 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...
