Method for building riprap levee island wall of offshore artificial island by large box barge

Abstract

The invention discloses a method for building riprap levee island wall of an offshore artificial island by a large box barge, comprising the following steps: (1) remodeling a large box barge; (2) dragging the large box barge to an area for building the riprap levee island wall of the offshore artificial island to facilitate the longitudinal centerline to be vertical to the axis of the riprap levee island wall of the offshore artificial island; (3) respectively parking transport ships at the both sides of the large box barge to unload stone material to the large box barge; (4) with excavators and waggon tremie riprap construction stone material piling platform of the large box barge provided, facilitating the large box barge to be driven to the stone piling platform by steel butt straps to riprap and deal with the slopes to build a section of riprap levee, repeating the process so as to facilitate the riprap levee island wall to move forward section by section to be formed and finally completed. In the invention, the on-water construction of the island wall of the offshore artificial island is transformed into onshore advance, thus reducing influence of stormy weather on the construction and greatly accelerating construction speed of the artificial island.

Description

technical field [0001] The invention relates to a construction method of an artificial island wall, in particular to a construction method of a riprap embankment wall of an open sea artificial island with a large tidal range and belongs to the technical field of hydraulic engineering. Background technique [0002] To build a deep-water port in some coastal areas lacking a deep-water coastline, it must be built in a deep-water area far from the coast, with a large tidal range and rapid tide, relying on artificial islands in the open sea, and connecting it to the land through bridges and pipelines. The artificial island project is the most important link in the construction of a deep-water port in the shallow sea area. After the completion of the laying of the underwater soft row and the sinking of the steel sheet piles, the artificial island project is transferred to the construction of the riprap island wall of the artificial island. The existing method of constructing the a...

Problems solved by technology

In order to speed up the construction of the artificial island, it is necessary to use a large number of positioning barges for positioning, and a large number of stone transport ships berthing and positioning barges throw stones. Each positioning barge must be positioned with a GPS positioning device, and tugboats are also required. The use cost is very high; and Positioning barges have poor wind and wave resistance conditions and cannot adapt to harsh sea conditions

[0003] At the initial stage of construction of the existing artificial island riprap wall, in the vast open sea site, there is no island shelter, the operation line of the riprap wall is long, and the construction conditions are harsh. There is no support and foothold on the site in the early stage of the project. The area is narrow, and in case of bad weather with strong winds and rough waves, the stone transport ship will be suspended, and the work on the riprap island wall will have to be suspended, which will seriously affect the construction efficiency
