Immersed tube floating-state barge-up method

Abstract

The invention relates to the technical field of immersed tube transportation, and discloses an immersed tube floating-state barge-up method which comprises the following steps: A, constructing a submerged bottom sitting area of a semi-submersible barge, and arranging a buttress system on the semi-submersible barge; b, operating the semi-submersible barge to dive and sit on the bottom, and floating the immersed tube in the dry dock; c, after the semi-submersible barge sits on the bottom, transporting the immersed tube to the position over the buttress system in a floating mode; and D, positioning and mooring the semi-submersible barge and the immersed tube, operating the semi-submersible barge to drain and float, supporting the immersed tube by the buttress system, supporting the immersed tube out of the water surface, and completing the barge-up work of the immersed tube. According to the immersed tube floating-state barge-up method, immersed tube barge-up can be completed through floating transportation, site limitation of construction of the barge-up wharf is avoided, transportation through the barge-up wharf, the rail and the trolley is not needed, immersed tube barge-up operation is easy, and the construction cost is also controlled.

Description

technical field [0001] The invention relates to the technical field of immersed tube transportation, in particular to a floating barge-up method for immersed tubes. Background technique [0002] When the water depth of the transport channel of the immersed tube is insufficient, the wet towing construction method is used to transport the immersed tube, and the channel needs to be excavated, which will cause a high increase in construction cost. Therefore, semi-submerged barges are usually used to transport the immersed tube to reduce The purpose of draft. [0003] At present, the specific method for the semi-submerged barge on the immersed tube is: set up a barge wharf at the connection between the immersed tube prefabrication factory and the water area, and arrange a continuous trolley track on the wharf and the semi-submerged barge, and arrange a semi-submerged barge at the front of the wharf. In the bottom area, first, the semi-submerged barge is positioned to the bottom ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a solution for the semi-submerged barge method of immersed tubes in the prior art, which requires the construction of a barge wharf and the laying of tracks, which has the problems of high construction costs, complicated operations, and the limitation of the wharf construction site. A floating barge-up method for immersed tubes avoids the site constraints of the barge-up wharf, and does not need to rely on the barge-up wharf, rails, and trolleys for transportation. The operation of the immersed tube barge-up is simple, and at the same time, the construction cost is controlled
