Description

A multifunctional guide frame

Technical Field

The utility model relates to the technical field of steel trestle construction, and more specifically, to a multifunctional guide frame.

Background Art

After entering the 21st century, my country's bridge development has entered the fast lane, and a large number of bridges across mountain valleys, rivers, lakes and seas are under construction or planning. Due to the need for material and equipment transportation and personnel passage during bridge construction, temporary trestles need to be built during bridge construction. In the construction of cross-river and cross-sea bridges, the length of the trestles often reaches several kilometers or even more than ten kilometers, and they are widely used.

The installation and disassembly of the pier will take up considerable equipment and resources, and the construction period is long. The installation and disassembly process also involves water and high-altitude operations, and requires a large number of operating platforms. The lower structure of the pier adopts a steel pipe pile foundation. When the fishing method is used to construct the steel pipe pile, in order to control the plane position and verticality of the steel pipe pile, a steel pipe pile guide frame is generally designed. After the steel pipe pile is inserted and driven into place, before the pile top distribution beam is installed, it is necessary to first dismantle the steel pipe pile guide frame, install the pile top distribution beam welding operating platform, and then install the pile top distribution beam. After the pile top distribution beam is installed, it is necessary to dismantle the pile top distribution beam welding operating platform, install the steel pipe pile connection system welding operating platform, and then install the steel pipe pile connection system. Since it involves the installation and disassembly switching of the guide frame and various operating platforms many times, the construction site often uses non-standard or simple guide frames and operating platforms, which poses a great safety hazard, the pier installation quality cannot be guaranteed, and the installation efficiency is low.
