Description

TECHNICAL FIELD

[0001] The utility model relates to bridge demolition protection technical field, more specifically, it relates to a protection device for bridge demolition. BACKGROUND

[0002] In the field of modern bridge engineering construction, bridge demolition operation has always been an important link with high technical requirements and high safety risks. At present, there are still serious technical challenges in the aspects of debris control and safety protection during the demolition process, and further exploration of more perfect solutions is needed.

[0003] In the process of bridge demolition construction, the most prominent safety hazard is the uncontrollability of debris falling. Since the demolition operation is usually carried out at a high altitude, the falling trajectory of concrete fragments, broken steel bars and various tools that may fall during construction is difficult to accurately predict and effectively control. These high-altitude falling objects not only produce a large amount of secondary splashing during the falling process, but also may deviate from the predetermined landing area due to external factors such as wind, resulting in significant expansion of the danger range. This situation poses a serious threat to the personal safety of pedestrians, vehicles and on-site construction personnel passing under the bridge. Once a falling accident occurs, it is easy to cause serious personnel casualties and property losses, and also causes significant safety hazards to the surrounding environment.

[0004] In order to cope with these safety challenges, the industry generally adopts a protection scheme of protective net combined with stand column. Although this scheme can effectively intercept falling objects in theory, it has exposed significant technical defects in actual application. The most prominent problem is that the connection and installation process between the protective net and the stand column is too complex and time-consuming. The traditional installation method usually requires multiple workers to operate cooperatively, involving complicated fixing steps. This not only reduces the construction efficiency, but also increases the construction cost. This complex installation method seriously affects the overall construction progress.

[0005] Although some improved quick connection devices have appeared on the market, trying to improve the installation efficiency of the protective net by simplifying the structure, these devices still have obvious limitations. These improved designs often pay too much attention to the convenience of the installation link, while ignoring the operation needs of the disassembly link. As a result, although the installation process has been simplified, when it is necessary to remove or adjust the position of the protective net, complex disassembly operations still need to be performed using professional tools. This asymmetric design not only does not fundamentally solve the problem of construction efficiency, but may increase the operation difficulty and safety risk of construction personnel in some cases.
