Abstract

The invention discloses a construction technique for conveying an immersed tube for a long distance with a self-propelling-type semi-submersible boat, and the construction technique is used for conveying the immersed tube from an immersed tube prefabrication factory to a foundation trench zone for assembly construction of the immersed tube. A first immersing operation zone is arranged in a temporary mooring zone of the immersed tube prefabrication factory; a second immersed operation zone is arranged beside the foundation trench; the immersed tube and an immersed tube assembly boat are loaded on the self-propelling-type semi-submersible boat at the temporary mooring zone and are conveyed to a turning zone; the immersed tube assembly boat and the immersed tube are unloaded in the second immersed operation zone; the immersed tube is floating-conveyed to the foundation trench zone for assembly construction of the immersed tube by tugs and the immersed tube assembly boat; and a mooring fitting-out zone does not need to be arranged beside the foundation trench, so that time and economic investment during previous preparation work is greatly reduced, and construction work efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of water transportation engineering construction in transportation, and in particular relates to a construction technology for long-distance transportation of immersed pipes in a self-propelled semi-submersible vessel. Background technique [0002] The underwater tunnel is formed by connecting multiple immersed pipes with huge volume and weight. The main types of immersed pipes are steel-shell concrete immersed pipe and reinforced concrete immersed pipe. At present, the processing and transportation method of immersed pipe mainly adopts the two-step method. That is, the immersed pipe is prefabricated and concrete is poured in the immersed pipe prefabrication plant, and the outfitting installation process is completed, and then the immersed pipe is long-distance floated to the immersed pipe construction base tank area for immersed pipe installation by hauling equipment. Due to the huge weight of the immersed pipe ...
