Self-returning offshore jacket platform and manufacturing method thereof
The invention belongs to the field of structural engineering in civil engineering and provides a self-returning offshore jacket platform and a manufacturing method thereof. The self-returning offshore jacket platform solves the problem that an original offshore platform is poor in anti-seismic property and is large in rigidity, high in strength, convenient to construct, good in anti-seismic property and high in durability. The self-returning offshore jacket platform is formed by a platform frame and a platform body, the platform body is arranged on the platform frame, and a plurality of horizontal platform struts and inclined platform struts are arranged among platform pipes. External steel tubes, internal steel tubes and corrugated tubes of the platform pipes are coaxially arranged from outside to inside in a sleeving mode, interlayer concrete is arranged between the external steel tubes and the internal steel tubes and between the internal steel tubes and the corrugated tubes, locating toggle pins are arranged on the external steel tubes and are movably connected with the internal steel tubes, built-in prestressed steel pull rods are arranged in the corrugated tubes, reinforcing ribs are fixedly connected to the outer sides of the external steel tubes, flange plates are fixedly arranged at the top ends of the platform pipes, and the upper ends of the flange plates are connected with the platform body or spliced with platform pipes.
