Embodiment

[0048] Such as Figure 1-Figure 3As shown, a method for floating lightering of immersed tubes of the present invention comprises the following steps:

[0049] A. Construct the bottom sitting area 2 for the submerged semi-submerged barge 1, and set up the buttress system 5 on the semi-submerged barge 1;

[0050] B. Operate the semi-submersible barge 1 to dive and sit on the bottom, and float the immersed tube 3 in the dry dock 4;

[0051] C. After the semi-submerged barge 1 sits on the bottom, the immersed tube 3 is floated to the top of the pier system 5;

[0052] D. Position the semi-submerged barge 1 and the immersed tube 3 for mooring, operate the semi-submersible barge 1 to drain and float, the pier system 5 supports the immersed tube 3, lift the immersed tube 3 out of the water surface, and complete the barge work of the immersed tube 3.

[0053] In this embodiment, the draft of the immersed tube 3 floating is 8.7m, and the height difference between the ebb and flow of ...

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 ...
