Abstract

The invention provides a bridge high-tower construction method, and belongs to the technical field of road and bridge construction. The bridge high-tower construction method comprises the steps that an initial segment of a tower column and a second section of the tower column and a third section of the tower column are constructed, then a climbing formwork body is installed on the tower column, alower tower column and a middle tower column are constructed, a fourth section of the tower column and above parts adopt climbing formwork construction, and the outer side of the climbing formwork body is totally sealed. The fourth section of the tower column and above parts adopt climbing formwork construction, punched steel meshes are used for totally sealing the outer side of the climbing formwork body, the sealed environment enables the internal operation environment of a climbing formwork to be significantly improved, and normal operation such as tower column reinforced steel bar bindingand concrete pouring in strong-wind weather is ensured. The invention further provides construction equipment used for the bridge high-tower construction method.

Description

technical field [0001] The invention belongs to the technical field of road and bridge construction, and in particular relates to a bridge tower construction method and construction equipment. Background technique [0002] With the construction of basic projects in our country, the field of bridge construction has gradually extended to the ocean. The offshore construction area is often windy and accompanied by typhoons, and the construction environment is extremely harsh. However, the scope of bridge construction in my country is mostly across rivers and inland connections. For the marine environment with frequent windy weather, there is not much experience in the construction of bridges and towers, and it is still in the exploratory stage. [0003] Offshore bridges have large spans, and most of them are high towers. The wind pressure increases with height, which makes the construction of high piers and high towers difficult and risky. At present, there is not much experien...
