Abstract

The invention provides a method for erecting and hoisting a heavy steel tower. The method includes setting an oblique platform; laying a buffer layer on the oblique platform; hoisting a first section of the heavy steel tower, simultaneously arranging the bottom of the first section on the oblique platform and using the buffer layer for buffering; implementing checking and adjustment when the gravity center of the first section and a fulcrum are located at the same position; and hoisting the first section to a working platform after adjustment. In addition, the invention correspondingly provides a system for erecting and hoisting the heavy steel tower. The method and the system have the advantages that the pre-assembly efficiency of the integral heavy steel tower can be effectively improved, and the method and the system are beneficial to accurately implementing operation for various tests.

Description

technical field [0001] The invention relates to a construction engineering technology, in particular to a method and system for erecting and hoisting a heavy steel tower applied to the construction of a large bridge. Background technique [0002] Large bridge steel tower segments generally require pre-assembly. For those with a larger length, due to the limitations of lifting equipment and factory building height, only horizontal pre-assembly can be used at present. Taking the new Bay Bridge in the United States as an example, the steel tower of the bridge has a first section and a second section, of which the height of the first section is about 47M, and the weight of a single steel tower is about 1300 tons. According to the prior art, basically all adopt pre-assembly after lying down. That is to say, the above-mentioned two sections of steel towers are put down and then pre-assembled. [0003] The main reason for choosing such an operation method is that the lifting cap...
