Abstract

The invention discloses a seabed type static cone penetrating device and a control method thereof. The seabed type static cone penetrating device comprises a penetrating mechanism, a winding mechanism and a flexible tooth-shaped post, wherein the penetrating mechanism comprises an aligning tube and a gear transmission mechanism; the winding mechanism comprises a winch and a guide plate; the flexible tooth-shaped post comprises a steel cable and a plurality of tooth-shaped post sections which are in sliding sleeve on the steel cable and are connected in series; one end of the flexible tooth-shaped post is in winding connection with a winch; the other end of the flexible tooth-shaped post gets across a guide disc and then passes through the aligning tube; adjacent tooth-shaped post sections positioned in the aligning tube are in splicing connection; the two sides of each tooth-shaped post section are engaged with the gear transmission mechanism; the flexible tooth-shaped post has a straight state and a bent state, is convenient to operate, and is high in stability; the tooth-shaped post sections are connected in series automatically, and are not additionally connected, so that seabed static penetration under a deep-layer condition is conveniently realized; and through a dual-engagement structure that the gear transmission mechanism is engaged with the two sides of each tooth-shaped post section, collimation degree and pressure needed for penetrating are guaranteed.

Description

technical field [0001] The invention relates to the field of marine engineering survey, in particular to a seabed static penetrating device for in-situ testing of seabed soil and a control method thereof. Background technique [0002] The basic physical and mechanical properties of the seabed soil, the bearing capacity of the foundation, and the possibility of soil liquefaction are important test items for the preliminary investigation of relevant marine engineering facilities, and the static penetration test based on the in-situ test method is to obtain the properties of these seabed soils. effective means. With the continuous development of the development and utilization of marine resources and the construction of marine engineering, static penetration testing of seabed soil has been more and more widely used in the fields of marine geological survey and marine engineering survey. [0003] Submarine static penetration testing is to obtain relevant test parameters by pene...
