A new bucket foundation with openable mud panels

Abstract

The invention discloses a novel barrel type foundation with mud panels capable of being stretched. The novel barrel type foundation comprises a round barrel foundation, a first bearing, a lower limiting groove, a lower stretching mud panel, a second bearing, an upper limiting groove, an upper stretching mud panel, a third bearing, a control rod and the like. The top of the round barrel foundationis welded to the bottom of the lower limiting groove, and the top of the lower limiting groove is welded to the bottom of the upper limiting groove. The first bearing is embedded in the center position of the bottom of the lower limiting groove, the second bearing is embedded in the center position between the top of the lower limiting groove and the bottom of the upper limiting groove, and the third bearing is embedded in the top of the upper limiting groove. The control rod with fan blades passes through the first bearing, the second bearing and the third bearing in sequence from bottom to top to be connected with the lower limiting groove and the upper limiting groove. The bottom of the control rod penetrates the lower limiting groove to make contact with the top of the round barrel foundation. The mud panel stretching function can be achieved in the foundation pressing and penetrating process by rotating the control rod, the bearing capability of the foundation is improved, and steering mooring can be achieved by means of mooring points arranged on large bearings.

Description

technical field [0001] The invention relates to a new type of foundation, in particular to a new bucket foundation with expandable mud panels. The foundation form adds an expandable mud panel to the traditional bucket foundation, so that its vertical and horizontal bearing capacity is improved. Greater improvement. Background technique [0002] The bucket foundation form is widely used in the design of offshore wind power foundations due to its economical, reusable, convenient installation, and strong applicability. When installing the bucket foundation, it is first hoisted to the positioning point. The effect will sink to a certain depth, so that a closed space is formed in the barrel, and the pump on the top of the foundation is used to pump water through the water outlet, so that a negative pressure difference is formed between the inside and outside of the barrel body. When the negative pressure difference inside and outside the barrel exceeds the soil When the side fri...

AI Technical Summary

Problems solved by technology

However, if the design penetration depth cannot be reached or the bearing capacity requirement is large, if the traditional bucket foundation is used, the design radius and height of the bucket foundation need to be increased, which is not very economical
