Embodiment Construction

[0031] Embodiments of the present invention are described in detail below:

[0032] like figure 1 As shown, the present embodiment provides a jacket 1, including at least two main conduits 10 and at least two secondary conduits 11, the primary conduits 10 and secondary conduits 11 are arranged alternately and form a circle, and the adjacent primary conduits 10 The pipe 10 is connected to the secondary conduit 11 through the intermediate strut 12, and several diagonal struts 13 are also arranged between the adjacent primary conduit 10 and the secondary conduit 11, with the connection point between the intermediate strut 12 and the primary conduit 10 as the second A node 100 , several diagonal braces 13 are connected between the main conduit 10 and the secondary conduit 11 in a fan shape with the first node 100 as the center. In the above-mentioned jacket 1, the middle strut 12 plays the role of connecting the main conduit 10 and the secondary conduit 11, and the fan-shaped arr...

Abstract

The invention discloses a guide pipe frame, a guide pipe frame foundation platform and a guide pipe frame construction method. The guide pipe frame comprises at least two main guide pipes and at least two secondary guide pipes, wherein the main guide pipes and the secondary guide pipes are staggered to surround by a lap; the main guide pipes and the secondary guide pipes, close to each other, are connected through middle support rods; multiple inclined support rods are additionally arranged between the main guide pipes and the secondary guide pipes close to each other; and with connecting points of the middle support rods and the main guide pipes as first nodes, the multiple inclined support rods are connected between the main guide pipes and the secondary guide pipes in a sector form with the first nodes as centers. The guide pipe frame, the main guide pipes and the inclined support rods between two secondary guide pipes near the main guide pipes are gathered on the first nodes to facilitate to transfer the load onto the main guide pipes, so that the stability and the fatigue resistance of the guide pipe frame are improved; and as the support rods are not connected in the whole guide pipe frame, and the guide pipes are only connected with the support rods, the numbers of the support rods and the nodes are decreased, the construction is more convenient, the materials are saved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical fields of marine engineering and electric power engineering, in particular to a jacket, a jacket foundation platform and a jacket construction method. Background technique [0002] Wind energy is a renewable and clean energy. When other renewable energy sources (such as biomass energy, tidal energy, etc.) are not yet mature, wind energy has become one of the primary choices to alleviate global environmental problems and energy crises. At present, among various foundation types of offshore wind turbines, single pile, jacket, underwater three-pile and above-water three-pile foundation types are the most commonly used types. [0003] Among them, the jacket foundation, as a relatively mature foundation type, has been widely used in the field of offshore wind power. Its structural feature is to provide a huge anti-overturning moment through a large chassis, and the connectors are composed of relatively flexible compone...
