AI Technical Summary

Technical Problem

When existing immersed pipe transportation methods encounter insufficient water depth or bridge hole height limit, they will greatly increase transportation costs or cannot be implemented, and require a large amount of waterway dredging and semi-submersible transformation.

Method used

A floating device for immersed tubes is designed, using a relatively set floating box and operating platform. Through the series combination lifting design, the draft depth and navigation height of the immersed tubes are reduced, and the requirements for waterway depth and bridge hole height limit are reduced.

Benefits of technology

In the case of insufficient water depth of the waterway or the bridge hole height limit, the dredging and semi-submersible transformation of the waterway are reduced or the transportation efficiency is improved.

Abstract

The present invention relates to the technical field of transporting immersed tubes, and discloses a floating device and a method for transporting immersed tubes, wherein the floating device comprises a pontoon 1 and a pontoon 2 which are arranged relatively to each other, and an operating platform is commonly connected above the pontoon 1 and the pontoon 2, and the operating platform comprises a pontoon platform 1, a pontoon platform 2 and a connecting crossbeam, and the pontoon platform 1 has a cantilever platform 1 extending out of the inner side of the pontoon 1, and the pontoon platform 2 has a cantilever platform 2 extending out of the inner side of the pontoon 2, and a single row or multiple rows of pulleys 1 are symmetrically arranged on the cantilever platform 1 and the cantilever platform 2, and the immersed tube is hoisted after the lifting rope connects multiple pulleys 1 in series. The floating device and the method for transporting immersed tubes of the present invention can lift the immersed tubes through the design of series combined hoisting, thereby reducing the requirements of the immersed tube transportation on the water depth of the waterway, and at the same time reducing the navigation height required for the transportation of immersed tubes, and can greatly reduce the water and soil damage and the increase of transportation cost when encountering the transportation road conditions of insufficient water depth of the waterway or the height limit of the bridge hole.
