Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a pedestrian passage that can be flexibly adjusted and fixed according to the width of a trench. Background Art

[0002] With the advancement of the urbanization process, the renovation projects of municipal infrastructure such as water supply, drainage, and gas are increasing day by day. These projects inevitably require the excavation of trenches for pipeline laying or other operations during construction. However, due to different construction environments and design requirements, the depths and widths of the trenches vary. Especially in municipal engineering, the excavation width of the trenches is commonly in the range of 1.2 - 1.8 meters. For trenches with a width less than 1.4 meters, traditional construction methods often do not set up a special pedestrian passage, resulting in workers having to cross the trenches by jumping or other means, which poses a huge safety hazard.

[0003] Currently, although there are some alternative solutions in actual construction, such as using scaffolding + wooden boards as a pedestrian passage, this method has obvious defects. As a temporary passage, the scaffolding + wooden boards lack necessary protective facilities, and workers are prone to falling accidents during walking. Especially in a wet or uneven trench environment, the safety hazard is more prominent. In addition, as the construction progress advances, the scaffolding boards need to be adjusted frequently, which not only reduces the construction efficiency but also increases the labor intensity of the workers.

[0004] Another common solution is a general standardized passage, which usually uses bolts to fix the passage to the edge of the trench. As the construction location changes, the general standardized passage needs to be disassembled and reinstalled frequently, which will cause damage to the trench surface, increase the burden of subsequent repair work, directly push up the construction cost, and slow down the project progress due to repeated disassembly and reinstallation.

[0005] Therefore, how to provide a trench passage device that can be flexibly adjusted and fixed according to the widths of different trenches, has a stable structure and necessary protective facilities, is convenient for disassembly and reuse, and does not damage the trench surface structure is a technical problem urgently to be solved in this field.
