Embodiment Construction

[0040] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0041] In this example, a "special lifting and vibrating shipwreck" is provided for carrying out on-site dredging and hoisting vibratory hammers and auxiliary grid sheet piles.

[0042]According to factors such as aviation height limit, seabed mud surface elevation, vibratory hammer lifting height, hoisting process requirements for steel sheet pile assembly pieces in the lower section of the sub-cell and hull stability requirements, therefore, in this example, the sub-cell is dedicated to lifting and vibrating The sunken ship uses a 6,000t-class deck barge as a special crane mother ship.

[0043] The special hoisting and hoisting vessels for whole driving can minimize the height of the slings, so that the length of the lower piles can be as long...

Abstract

The invention discloses a special lifting and vibration-driving ship for integrated driving of cell type steel sheet pile large cylinders and vice cells. The special lifting and vibration-driving ship comprises a special integrated driving crane ship mother ship provided with a special lifting device and special vibration-driving equipment. The special lifting device is fixed to the crane ship mother ship, is of a T-shaped two-arm structure and is composed of two lifting devices in left-right symmetry. The special vibration-driving equipment and the special lifting device cooperate to be used for integrated lifting and integrated vibration-driving of the cell-type steel sheet pile vice cells. By the adoption of the special lifting and vibration-driving ship, all working procedures, in the whole process of steel sheet pile vibration-driving, comprising steel sheet pile lifting, descending and vibration-driving can be completed at a time, there is no need to perform unclasping or replace pile hammers or perform seam vibration-driving after steel sheet pile lifting and descending, and therefore working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a construction technique for a large cylinder auxiliary cell of a lattice-type steel sheet pile, in particular to a crane ship used for installation and construction of a large-cylinder main cell of a lattice-type steel sheet pile. Background technique [0002] Artificial islands are generally artificially built land in shallow waters near the coast. As a place for offshore operations or other purposes, most of them are connected to the shore by trestles or undersea tunnels. In a coastal country with developed modern industry, the dense population and crowded cities along the coast have greatly restricted the further development and construction of new enterprises and public facilities, and the problems of residence, traffic, noise, water and air pollution in the original city itself are also difficult. solve. Therefore, the construction of artificial islands has changed or improved the above-mentioned difficult problems. Art...
