Embodiment Construction

[0034] 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.

[0035] In the construction process of the lattice-type steel sheet pile island wall of the artificial island formed by backfilling the cofferdam formed by the large cylinder of the lattice-type steel sheet pile and the breakwater, the 1 / 4 round steel sheet pile assembly pieces obtained in advance must be assembled according to the construction process, but The diameters of the large cylinders of lattice-type sheet piles are 26.9m and 31.194m respectively, and the height of the 1 / 4 cylinder of the main grid sheet piles ranges from 23.6 to 37.1m (that is, the length of the steel sheet piles), plus the limitations of on-site hoisting conditions, As a result, 1 / 4 large cylinder pre-assembled parts (that is, 1 / 4 round steel sheet pile assembly pieces)...

Abstract

The invention discloses a transportation method for pre-assembled main cellular sheet pile 1/4 cylinders of cellular steel sheet piles. The method comprises the steps of (1) arranging transport supports on transport ships, wherein the supports are fixed on decks of the transport ships and loaded in a two-side longitudinal symmetrical mode; (2) assembling main cellular sheet pile 1/4 cylinders on the transport supports by using steel sheet piles to obtain corresponding 1/4 circular steel sheet pile assembly sheets; and (3) hauling the transport ships with the 1/4 circular steel sheet pile assembly sheets arranged through towage ships to construction sites. According to the transportation method, problems in the prior art can be solved effectively, and the shipping stability and safety of the ships are guaranteed.

Description

technical field [0001] The invention relates to a construction technology of an artificial island on the sea, in particular to a method for pre-assembled 1 / 4 cylinder transportation of large cylinder main lattice sheet piles of lattice type steel sheet piles. 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. Artificial island is on...
