Abstract

The invention discloses a down-pitch diving shipment method of a large caisson for a semi-submersible barge. The method comprises the following steps: jacking the large caisson by using a jacking air bag; using the jack to statically support and changing trolleys to carry the large caisson; translating the trolleys along a longitudinal rail and a transverse rail to a leveled and butt-joint part of a deck and a barge platform, and continuously translating the ultra-big caissons to a designated place of the deck through a second pull-shift air bag and then fixing; shipping the ultra-big caissons to the designated place and mounting the ultra-big caissons in a down-pitch diving manner; wherein a butt-joint buckle is arranged on a tank body with a side opening on the barge platform, and the side wall of the upper part of the butt-joint buckle is pivoted with the barge platform; the transverse rail is a stage-like rigid plate body which extends horizontally from the deck of the semi-submersible barge, and a butt-joint plate of the transverse rail can be detachably inserted into the butt-joint buckle. According to the method, on the basis of ensuring the stable movement of the large caisson, the total movement distance of the large caisson can be effectively reduced, and the total movement time can be shortened.

Description

technical field [0001] The invention relates to the technical field of shipping large caissons, in particular to a method for shipping large caisson semi-submersible barges with bow tilting. Background technique [0002] A caisson in marine engineering is similar to a box with a closed bottom and an open top. Due to the good overall stability of the caisson structure, fast construction speed, and durability, it is widely used in port projects with good foundations such as piers, trestles, and breakwaters. For the convenience of transportation, caissons are generally manufactured on the shore or in docks, and then Float in place, fill with water and sink to make it sink smoothly to the leveled foundation or riprap foundation bed for fixed use. [0003] Large caissons are larger in size and heavier than ordinary caissons, and cannot be floated and placed in place by ordinary docks. Contents of the invention [0004] It is an object of the present invention to solve at leas...
