Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a protective device for bridge construction. Background Art

[0002] A bridge is a structure built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. A viaduct is a type of bridge. A viaduct is a bridge with high supporting towers or pillars that cross valleys, rivers, roads, or other low obstacles. With the development of cities, traffic congestion, dense buildings, and the difficulty of widening streets, the use of viaducts can disperse traffic density and improve transportation efficiency.

[0003] Most bridges are built on existing streets. There is a risk of falling objects during construction. Currently, protection is provided by blocking the construction section and building fences around the blocked section.

[0004] The existing patent (Announcement No.: CN219045101U) is a protective device for bridge construction. The device sets up a protective net at the bottom of the bridge to catch falling objects. A predetermined height is left between the protective net and the ground. Vehicles and pedestrians pass through the bottom of the protective net, ensuring normal construction without affecting normal traffic and with high safety.

[0005] However, the above patent still has certain defects. The protective device for bridge construction uses a protective net to catch falling objects. However, after being placed for a long time, the number of falling objects caught will increase, causing certain damage to the protective net, and even causing the protective net to rupture. If the protective net cannot be replaced quickly, it will cause certain safety hazards to the people under the protective net. At the same time, there will be a certain impact force when falling objects fall onto the protective net. The spring can only have a certain buffering effect and cannot enhance the stability of the device. It may cause shaking, which is dangerous.

[0006] Therefore, a protective device for bridge construction is proposed. Utility Model Content
