Embodiment Construction

[0031] The embodiment of the present application solves the technical problem that there is no method in the prior art for hoisting a steel cable tower with an irregular shape and a heavy weight by providing a lifting method for the cable tower.

[0032] The technical solution in the embodiment of the present application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0033] A hoisting method for a cable tower, the method comprising:

[0034] Fixing the tower head of the steel cable tower in the rectangular bracket, and fixing lifting lugs at the tail of the rectangular bracket and the steel cable tower respectively;

[0035] Connect the two pole beams to the two gantry cranes respectively;

[0036] Fix the connecting plates of the two lifting lugs under the shoulder beam respectively;

[0037] Move the gantry crane to the top of the steel cable tower, and fix the two lifting lug connecting plates on the lifting lugs at the end of th...

Abstract

The invention discloses a steel cable tower hoisting method. The method comprises steps of fixing a tower head of a steel cable tower in a rectangular rack, fixing hoisting lugs on the rectangular rack and the tower tail of the steel cable tower, connecting tow carrying pole beams to two gantry cranes respectively, fixing two hoisting lug connection plates under the carrying pole beams respectively, moving the gantry cranes over the steel cable tower, fixing the two hoisting lug connection plates to the hoisting lugs of the tower tail and the tower head, hoisting the steel cable tower, moving the two gantry cranes, hoisting the steel cable tower to a turning-over position, and finishing hoisting of the steel cable tower. The tower head of the steel cable tower is fixed in the rectangular rack and the tower head and tower tails are respectively connected to the two gantry cranes, so the steel cable tower can be hoisted, an auxiliary tower column and decoration blocks of the tower head can be protected and damage to the auxiliary tower column and the decoration blocks during the hoisting can be avoided.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a hoisting method for a steel cable tower. Background technique [0002] The Zhuhai-Hong Kong-Macau Bridge is a cable-stayed bridge with a central parallel single-cable plane and three tower steel box girders. The steel cable tower weighs 2,560 tons and has an overall size of 19Mx20Mx105M. The steel cable tower includes the main tower, auxiliary tower and decorative blocks. . [0003] Due to the constraints of the on-site hoisting conditions, the steel cable tower needs to be turned over, and the steel cable tower needs to be hoisted to the turning area before turning over. However, in the prior art, there is no method for hoisting such a component with irregular shape and heavy weight. Contents of the invention [0004] The application provides a hoisting method for a steel cable tower, which solves the technical problem that there is no method in the prior art t...
