Problems solved by technology
[0002] With the rapid development of my country's social economy, the scale and number of bridge projects have increased rapidly. Bridges are an important link in traffic engineering and an important part of infrastructure construction. For hoisting and installation of curved steel towers, the structure of curved steel towers is complex in shape, difficult to manufacture and install, and requires high construction accuracy. It is often difficult to ensure the installation accuracy of curved structures during construction. Therefore, we propose a curved steel tower The construction method of tower positioning installation is used to solve the above problems

The invention discloses a construction method for positioning and installing a curved steel tower. The construction method comprises the following steps that all sections of the steel tower are pre-assembled and matched; hoisting is carried out through a floating crane, coarse positioning superposition is carried out through an inter-segment positioning mechanism, and temporary locking is carriedout through bolts; an installation information model is constructed by scanning node data of installation sections, the real-time installation information model of the steel tower is compared with a design information model to obtain an installation deviation value, and the positions between the sections are adjusted according to the installation deviation value so as to achieve accurate positioning; and after the steel tower is completely positioned, welding is conducted on a segment connector, and segment installing and fixing are completed. Through coarse positioning and fixing during hoisting and scanning of a component information model, the installation information model is compared with the design information model to obtain the installation deviation value, the segment position isaccurately adjusted, finally, the accurately-positioned segment connector is welded and fixed, positioning and installation of the curved steel tower are achieved, and the construction accuracy and reliability can be ensured.
Description
Technical field [0001] The invention relates to the technical field of bridge installation, in particular to a construction method for positioning and installing curved steel towers. technical background [0002] With the rapid development of China's social economy, the scale and quantity of bridge projects have increased rapidly. Bridges are an important link of traffic engineering and an important part of infrastructure construction. When some main towers of suspension bridges across rivers and rivers are constructed, it is often necessary to hoist and install curved steel towers. The curved steel towers are complex in structure, difficult to manufacture and install, and require high construction accuracy. Therefore, it is often difficult to ensure the installation accuracy of curved steel towers during construction. Therefore, we propose a construction method of positioning and installation of curved steel towers. Inventive content [0003] The purpose of the present inventio...
