AI Technical Summary

Technical Problem

The existing guide frame has low rigidity, poor height, and cannot provide a working platform, resulting in low construction efficiency and poor safety of steel trestle bridges. In addition, the jointing of steel pipe piles is complicated, which affects construction quality and safety.

Method used

Design a symmetrical guide frame, including an upper crossbeam, vertical rods, a lower crossbeam, and a railing. The work platform is located below the Bailey beam and adopts a full double-span I-beam structure, integrating guidance and work platform functions, providing a spacious workspace and safety protection.

Benefits of technology

It improves the positioning accuracy and construction efficiency of steel pipe piles, reduces the number of splicing operations and welding risks, enhances construction safety and overall stability, and reduces construction costs.

Abstract

The invention discloses a temporary steel trestle steel pipe pile inserting and driving guide frame for underwater spanning tower construction and a construction method, and relates to the technical field of steel trestle construction. Most existing guide frames are bailey beam modified frames, have the problems that steel pipe piles need to be lengthened for multiple times, a distribution beam construction platform cannot be provided and the like due to the fact that the existing guide frames are low in rigidity and located on the upper portions of bailey beams, and influence construction quality, efficiency and safety. The guide frame comprises an upper cross beam, vertical rods, a lower cross beam and a fence, and the upper cross beam and the lower cross beam are connected through the vertical rods to form a sunken operation platform; the lower cross beam exceeds the upper cross beam in length, a guide hole is formed in the extending part of the lower cross beam, and the guide frame is used for completing operations such as steel pipe pile positioning, inserting and driving, lengthening, pile top opening and distribution beam installation. Through the design of the sinking type platform, the length of a single-time hoisting pile is increased, the lengthening frequency is reduced, the sinking type platform does not need to additionally erect a platform, multi-procedure continuous operation is achieved, the construction efficiency, quality and safety are remarkably improved, and the construction cost is reduced.
