Embodiment Construction

[0022] The invention replaces a semi-submerged barge or a floating dock, and is suitable for a bottom-mounted combined buoy box device and a method for using and dismantling it, which is used for land construction and launching of a self-elevating platform. figure 2 It is a schematic diagram of the composition of a single seat-bottom combined floating tank device. It can be seen from the schematic diagram that the composition of the device of the present invention is as follows from bottom to top: concrete box foundation 1, closed steel box 2, hollow steel structure support unit 3, and steel structure construction platform 4. In order to ensure the bearing capacity of the bottom-type combined floating tank device and save the cost, the closed steel box 2 can be selected as a reinforced concrete box structure, or the concrete The box body foundation 1 and the closed steel box body 2 are made into one. When in use, a drainage pump is placed in the airtight box, and the ballast...

Abstract

The invention discloses a device and a method for launching after flat ground construction of a self-elevating platform. The device comprises a concrete box body foundation 1, closed steel box bodies 2, hollowed-out steel structure supporting units 3 and steel structure construction platforms 4. All components of the device disclosed by the invention are hermetically and fixedly connected, wherein the closed steel box bodies 2 have a ballast adjusting function, water can be filled into a buoyancy box during use to enable the buoyancy box to sink down to a seabed base and the drainage of water in the buoyancy box is finished during removal to enable the buoyancy box to float and move. After the platform is constructed on the land of a wharf, the device is divided into a plurality of different units according to the features of the platform, the different units are configured on the seabed of the wharf in a manner of filling ballast water, fixed sliding rails are laid on the wharf, the platform is moved to sliding rails on the sea, then the entire platform is elevated, the sliding rails are removed, finally the ballast water in the buoyancy box is drained and the buoyancy box floats and moves away. The device can replace the expensive semi-submersible barge or floating dock, has the features of high economic performance, high safety in use and convenience in assembling and disassembling, and is a key device for assisting of completing launching after flat ground construction of the self-elevating platform.

Description

technical field [0001] The invention relates to the technical field of ocean engineering, and more specifically, to a launching auxiliary device and a use method of a self-elevating platform. Background technique [0002] Flat ground construction technology has been widely used in the construction of jack-up platforms by international and domestic shipbuilding enterprises, but the way to complete the launch requires the use of expensive semi-submersible barges or floating docks. If we can find a device that replaces semi-submersible barges or floating docks to complete the launch, which is more economical and safe, it can greatly save construction costs and effectively expand the production capacity of shipbuilding enterprises. [0003] Therefore, it is necessary to research and develop a device that can replace the traditionally expensive semi-submersible barges and floating docks and assist the self-elevating platform to complete the launch with the help of the self-elevat...
