Embodiment

[0014] A method for sinking a cylindrical foundation with built-in buoy towage. The cylindrical foundation 1 is divided into four compartments 8-I, II, III, and IV with fan-shaped cross-sections through a bulkhead 2. There is a discharge control valve 3, at least one is provided in each cabin, and the buoy is arranged inside the cylindrical foundation 1. The buoy also adopts a split structure, which consists of four phases with the cylindrical foundation 1 cabin 8-I, II, III, IV. Matching buoys 4-I, II, III, IV are formed, each sub-pony 4-I, II, III, IV top is provided with an exhaust valve 5, each sub-pony 4-I, II, III, IV bottom A drain valve 6 is provided, and a vibration isolation pad 7 is provided between the sub-pontoons 4-I, II, III, IV and the cylindrical foundation 1; after the cylindrical foundation 1 is towed in place, the built-in sub-pontoons 4-I, II , III, and IV are provided with the exhaust valve 5 and the drain valve 6, and the air in the sub-floor 4-I, II, II...

Abstract

The invention relates to a built-in buoy towing barrel-shaped foundation sinking method, wherein a barrel-shaped foundation is divided into four cabins with fan-shaped sections through a compartment, a buoy is arranged inside the barrel-shaped foundation and comprises four branch buoys which are matched with the cabins of the barrel-shaped foundation, and a vibration isolating cushion is arrangedbetween the branch buoys and the barrel-shaped foundation; after the barrel-shaped foundation is towed in place, exhaust valves and drain valves arranged on the built-in branch buoys are opened, air in the branch buoys is pumped to the inside of the barrel-shaped foundation, the branch buoys can slowly retreat from the barrel-shaped foundation and sinks to the water bottom, then the barrel-shapedfoundation is towed to an accurate sinking position, and a discharge control valve at the top of the barrel-shaped foundation is opened to discharge gas and water to finish the sinking operation of the barrel-shaped foundation. The invention has the advantages that the buoy can be conveniently reclaimed through replacing the gas in the built-in buoy to the inside of the barrel-shaped foundation, and meanwhile, the barrel-shaped foundation has floating stability, sinking in place is ensured to be safely and effectively carried out, and the method has convenient construction, is simple and has remarkable cost advantage.

Description

Technical field [0001] The invention relates to the sinking technology of a cylindrical foundation in port, ocean, water conservancy and bridge engineering, in particular to a method for sinking a cylindrical foundation towed by a built-in buoy. Background technique [0002] At present, in port, ocean, water conservancy and bridge projects, the sinking construction of the cylindrical foundation towed with built-in buoys is usually involved. The current method of sinking the cylindrical foundation with built-in buoys towed has the problem of difficult recovery of the built-in buoys. Contents of the invention [0003] The object of the present invention is to solve the above existing problems and provide a method for sinking a cylindrical foundation towed by built-in buoys. The sinking method has the advantages of simple construction method, convenient and safe operation, easy recovery of built-in buoys, and outstanding economic efficiency. [0004] Technical scheme of the p...
