The invention relates to a construction method of a prefabricated hollow pier installation structure. The construction method comprises the following steps: 1) construction preparation; 2) ring steelbar cage binding construction; 3) prefabricated hollow pier hoisting construction; 4) prefabricated hollow pier positioning and connecting; 5) foundation steel mould layout; and 6) foundation concretepouring. The construction method has the advantages that not only can the efficiency and quality of the binding construction of a ring steel bar cage be improved, but also the difficulty of the binding and positioning of the steel bar cage can be effectively reduced; the hoisting connection reliability of a prefabricated hollow pier is high and the hoisting construction difficulty is low, the hoisting construction efficiency can be improved, and the hoisting positioning accuracy can be improved; a prefabricated hollow pier has high connection strength with a bearing cap and a positioning pierand positioning is accurate, which can greatly improve the integrity of the foundation part of the prefabricated hollow pier and optimize the structural stress; and the construction method can effectively improve the accuracy of the installation and positioning of a foundation steel mould, enhance the integrity of the foundation steel mould structure, and improve the efficiency of the formwork erecting construction.
Description
technical field [0001] The invention relates to a construction method of a prefabricated hollow pier installation structure that can improve the quality of on-site construction and the integrity of the construction structure, reduce the difficulty of environmental protection, and improve the efficiency of on-site construction. It belongs to the field of bridge engineering and is suitable for prefabricated hollow pier installation projects. Background technique [0002] The prefabricated hollow pier of the bridge adopts factory prefabrication and on-site assembly technology, which can speed up the construction progress while improving the mechanized construction level, reduce the impact of construction on the surrounding environment, and has a good engineering application prospect. However, during the construction of the prefabricated hollow pier installation structure, the construction quality is often affected by the hoisting connection, spatial positioning accuracy, connect...
