Embodiment

[0043] This scheme provides a caisson transportation construction method in a restricted channel, which specifically includes the following steps:

[0044] S1. Carry out pre-shipment preparations for the prefabricated caissons;

[0045] S2. After lifting the caisson to a first predetermined height with a jacking device, install the auxiliary floating airbag on the outer wall of the caisson;

[0046] S3. Transport the lifted caisson to the hoisting area of ​​the wharf by means of a handling device;

[0047] S4. After the hook of the lifting ship drives the spreader to move to the top of the hoisting area, the hanger is lowered so that the height of the spreader is a second predetermined height, and the second predetermined height is used to ensure that the spreader can be connected with the caisson;

[0048] S5. After the sling is connected to the caisson, execute the safety test procedure, and judge whether the safety test procedure is passed, if so, proceed to step S6, other...

Abstract

The invention relates to the technical field of overwater construction, in particular to a caisson transportation construction method in a limited channel, which comprises the steps of preparing before transportation, transporting a caisson to a wharf, partially hoisting the caisson into water through a crane ship, transporting the caisson to a safe area and installing the caisson at a preset installation position. When the caisson is conveyed in water, the floating transportation mode and the hoisting transportation mode are combined, and the problem that in the prior art, a conventional caisson transportation method cannot completely meet the requirement for rapid, economical and safe transportation of medium and large caissons in the limited channel is solved; the caisson water transportation method is innovated by combining the floating transportation mode and the lifting transportation mode, the respective advantages of the floating transportation mode and the lifting transportation mode can be fully played, and the applicability, safety and efficiency of caisson transportation are improved.

Description

technical field [0001] The invention relates to the technical field of water construction, in particular to a caisson transportation construction method in a restricted waterway. Background technique [0002] In view of the huge advantages of small water workload, fast construction speed and good overall stability, caissons have been widely used in the construction of hydraulic structures such as docks and bridge foundations. Usually, caissons are prefabricated in factories first and then transported To the construction site for installation. With the popularization of the application of caissons in the marine environment, the continuous improvement and innovation of water transportation methods are becoming more and more important. [0003] The caisson construction process is generally: caisson prefabrication - caisson shipment - caisson launch - water transport - caisson positioning installation, in which the caisson shipment mainly adopts floating transportation, semi-su...
