Description

A operation platform for hanging basket construction balladeur train is dismantled

Technical Field

The utility model relates to the field of bridge construction, in particular to an operating platform for disassembling a hanging basket construction sliding frame.

Background

The hanging basket construction refers to the operation of segmenting the cantilever on site by adopting a hanging basket method when pouring a cantilever beam bridge with larger span. It does not need to erect a support and does not use a large crane. The hanging basket is manufactured in a factory, prepressing is carried out after field installation, after the safety of the hanging basket is checked and the deflection of an outer guide beam is detected, a template of a box beam, binding steel bars, installing corrugated pipes and pouring concrete can be erected, prestress paving is carried out after a pair of beam sections are poured, then the hanging basket is moved forwards, pouring of the next section of box beam is carried out until a cantilever end is reached, before the hanging basket is moved, in order to avoid abrasion of a poured bridge body caused by a bottom die on the hanging basket, the bottom die needs to be moved downwards firstly, so that the bottom die and the bridge body can move without obstacles after a certain gap is formed between the bottom die and the bridge body, but in order to enable the bottom die to be more balanced in the installation of the traditional hanging basket bottom die, the outer guide beam on the bottom die penetrates through a sliding frame and is hung on the hanging basket through the sliding frame, therefore, the sliding frame hanging the outer guide beam needs to be detached before the bottom die is moved, but because the sliding frame is in a suspended state, accidents easily occur in the disassembly process, and great potential safety hazards exist.
