The invention provides an integrated immersed tube immersing and locking-backfilling vessel and a construction technology, and belongs to the technical field of immersed tube tunnel construction. The integrated vessel comprises a double-hull vessel and the double-hull vessel comprises a first hull and a second hull, wherein the first hull and the second hull are arranged in parallel, and the upper part of the first hull and the upper part of the second hull are connected through a deck bridge; an immersed tube to be immersed is located between the first hull and the second hull and is located below the deck bridge; immersing equipment used for immersing the immersed tube is arranged between the deck bridge and the immersed tube; and backfilling guide tubes used for sand backfilling are arranged between the first hull and the second hull and on the left side and the right side of the immersed tube, are vertically connected to the bottom of the deck bridge and penetrate through the deck bridge. According to the integrated vessel and the construction technology, immersed tube immersing and locking-backfilling are integrated, the construction technology of an immersed tube tunnel is simplified, and the construction efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of immersed tube tunnel construction, and in particular relates to an immersed tube sinking, locking and backfilling integrated ship and a construction process. Background technique [0002] At present, the main construction method of underwater tunnels is the prefabricated pipe segment sinking method, and the tunnels constructed by this method are immersed tube tunnels. In the construction of immersed tube tunnels, the immersed tubes are usually placed in the foundation trench accurately by using the sinking equipment and auxiliary positioning system, and then the positioning system is used to lock the position of the immersed tubes, and the backfill equipment is used to fill the foundation trenches on both sides of the immersed tubes. Backfill the sand to complete the locking and backfilling of the immersed tube, so that the immersed tube can be firmly installed in the foundation groove. However, this exi...
