Embodiment

[0036] In this embodiment, the design water level is as follows:

[0037] Design high water level 5.41m (accumulation frequency of high tide 10%)

[0038] Design low water level 0.47m (low tide cumulative frequency 90%)

[0039] The water depth of the proposed bucket breakwater is about -5m.

[0040] Such as figure 1 , figure 2 As shown, in this embodiment, the axial length of each group of barrel members is 20m, the installation distance between two adjacent groups of foundation structures is 1.0m, and the distance between the upper barrels is 10cm-20cm.

[0041] The dimensions of the foundation barrel are: the long axis of the lower elliptical foundation barrel is 30m, the short axis is 20m, the height is 9.0m, the thickness of the outer wall is 40cm, the wall thickness of the partition is 30cm, and the thickness of the top plate is 40cm; the wall thickness of the upper barrel body is 35cm, The barrel is 15.28m high.

[0042] The typical overall dimensions of each grou...

Abstract

The invention discloses a transportation and installation process of a base barrel body of a barrel type breakwater, wherein the base barrel body is hauled to a construction field through a tugboat and a semi-submerged barge; a floating air bag is arranged on the base barrel body; the balance of the base barrel body is adjusted by inflating the floating air bag; and the base barrel body is sunk by deflating the floating air bag. After the technical scheme is adopted, because the semi-submerged barge is adopted to transport the base barrel body, the base barrel body is transported more stably and quickly; because of the large tonnage semi-submerged barge, the base barrel body can be transported under the condition with large stormy waves; and due to the floating air bag, the processes of the floating, the installation and the positioning of the base barrel body can be effectively controlled and kept balanced all the time.

Description

technical field [0001] The invention relates to a port protection project, in particular to a process for carrying and installing a bucket-type breakwater foundation bucket. Background technique [0002] A new type of breakwater barrel component is often used in the construction of existing offshore breakwater projects, usually consisting of a base barrel and several upper barrels. The base barrel of this barrel element is usually prefabricated by reinforced concrete , ranging from hundreds of tons to thousands of tons. How to move such a large structure from the prefabricated site to the pre-embedded site and accurately install and position it is a difficult problem. [0003] The traditional method generally uses large-scale hoisting equipment to hoist the prefabricated parts on the barge, and the barge is transported to the installation site, and then hoisted to the installation point by the marine hoisting equipment, and then the structure is sunk into the soil by means ...
