It is gradually becoming one of the competitive structures in the large span bridge.
When steel truss bridges cross existing traffic, especially deep water areas, large cantilever construction is often adopted to guarantee the safety of construction and the requirements of construction period, in order to guarantee the quality and safety of construction. , Install a temporary deduction tower and provide anchors for the erection of all cantilever beams on steel truss bridges.

Pre-installation of tower roots and steel truss bridges The buckle towers and steel truss bridges are often hinged to prevent the buckle tower nodes from being destroyed by a large bending moment during construction. However, the buckle tower is assembled section by section. To ensure the geometric immutability of the tower, the bottom node is temporarily locked and secured before closing the tower and installing a temporary wind cable. When the installation of the wind rope is completed, the lock structure is released and the conversion of the lock tower system is completed. However, after the anchoring is hinged, the installation process of the tower will be biased due to the effects of installation errors, wind loads, etc., which poses a serious safety risk to the construction and is also a steel truss bridge. Affects the spelling alignment of. However, the pad structure
It is difficult to achieve accurate vertical adjustment during mating, and as the height of the deduction tower increases, the unbalanced load that can withstand the paper pad structure gradually increases, and the main truss structure It is easy to crush the rod.
