Embodiment Construction

[0025] The present invention will be further described below in conjunction with drawings and embodiments.

[0026] Such as Figure 1 ~ Figure 3 Shown, the present invention comprises the following steps:

[0027] (1) Modification of cube barge 1

[0028] The 2000-ton cube barge 1 of the present embodiment is suitable for open sea construction, and its hull size is 60 * 15 meters 2 , on the decks of the bow and stern of the 2000-ton cube barge 1, respectively place a 120-ton crawler crane 11 and a 65-ton crawler crane 12, wherein the length of the boom 111 of the 120-ton crawler crane 11 is 33 meters, It can meet the pressure pile construction in a large range. The use of the crawler crane is convenient and flexible. During offshore construction, the crawler crane drives the upper cube barge for construction; after the offshore construction is completed, the crawler crane drives away from the cube barge, and both the crawler crane and the cube barge can be used for other pu...

Abstract

The invention discloses a method of pile-assembly and pile-pressing of a double crane pile driving barge for construction of an off-shore artificial island, comprising the following steps: (1) refitting a double crane box barge suitable for off-shore artificial island construction; (2) hoisting single-sheet steel plate piles to a pile area of the box barge; (3) assembling a group of 3 single-sheet steel plate piles into finished products of steel plate piles on the double crane pile driving barge; (4) facilitating the crane to insert lengthened steel sheet piles at the initiating terminal under underwater mud level; (5) facilitating a vibration hammer to press the lengthened steel sheet piles at the initiating terminal to a position the steel plate heads appear on the water surface; (6) facilitating the vibration hammer to press the steel sheet piles in sequence, facilitating the steel plate piles and the lengthened steel plate piles at the initiating terminal, the steel plate piles and the steel plate piles to be interlocked transversely pile by pile to form a steel plate wall under underwater mud level; (7) finishing pressing the lengthened steel plate piles at the initiating terminal to facilitate the head parts thereof to appear on the water surface. In the invention, the pile-assembly and pile-pressing are carried out simultaneously on the double crane pile driving barge with work efficiency being 9.6 times of the work efficiency of the prior art, thus greatly shortening construction cycle.

Description

technical field [0001] The invention relates to a construction method of an artificial island foundation, in particular to a steel sheet pile assembling and pile pressing method used for waterproofing an open sea artificial island with a large tidal range and belongs to the technical field of hydraulic engineering. Background technique [0002] In some coastal areas lacking deep-water shorelines, deep-water large ports must be built in deep-water areas far from the coast, with large tidal ranges and high tides, relying on artificial islands in the open sea, and connecting them to the land through bridges and pipelines. The artificial island project is the most important link in the construction of a deep-water port on a shallow coastline. In such an area, there is often no island shelter, and the seabed is severely scoured by the current to form a scour pit. For example, only the existing soft row is used to protect the bottom of the embankment If the method is used, the sta...
