Description

Technical Field

[0001] The utility model relates to the field of construction tools, in particular to a deep foundation pit ladder cage reinforcement auxiliary tool. Background Art

[0002] In the complex environment of current deep foundation pit construction, ensuring the safe entry and exit of workers is not only an important part of construction management, but also a prerequisite for ensuring the progress and quality of the project. With the continuous expansion of urban construction, the number of deep foundation pit projects has increased, and their depth and scale have also increased. This has put forward higher requirements on the design and safety performance of the assembled pedestrian ladder cage, the passage facility for workers in the foundation pit.

[0003] Although the traditional assembled pedestrian ladder cage can be quickly installed and disassembled, making it easier for workers to enter and exit the foundation pit, its limitations gradually become apparent when working in deep foundation pits. Due to the large depth of the foundation pit, the ladder cage is correspondingly extended, and there is a lack of effective reinforcement measures in the middle, resulting in the ladder cage's lack of torsion and overturning resistance when subjected to external forces such as wind loads and snow pressure. The overall structural stability is poor and it is difficult to meet the requirements of safety regulations. Especially in extreme weather conditions, such as strong winds and heavy snow, the ladder cage is very likely to shake, which not only affects the safety of workers, but may also cause safety accidents, resulting in construction suspension, and increasing project risks and costs.

[0004] In addition, when a traditional ladder cage is used at a time, if too many people go up and down at the same time, it will also produce a large shaking phenomenon due to the concentrated load, further exacerbating the safety hazard. This not only reduces work efficiency, but also seriously affects the workers' work experience and psychological state. Therefore, it is urgent to develop a new type of ladder cage reinforcement tool. Utility Model Content

[0005] The utility model mold aims to solve the problem that the linear length of the ladder cage is too long due to the deep foundation pit, resulting in poor safety and stability of the ladder cage.
