Description

Technical Field

[0001] The present application relates to the technical field of municipal roads and bridges, and specifically to an impact buffer device for a municipal road and bridge foundation pit. Background Art

[0002] Municipal roads and bridges are an important part of the urban road traffic system. They are mainly used to connect roads, transportation hubs, rivers and other places for vehicles and pedestrians to pass. Municipal roads and bridges carry the important task of connecting various areas of the city, promoting economic development and improving people's livelihood. Their safety is directly related to the travel safety of the general public and the smooth operation of urban traffic.

[0003] For example, the Chinese utility model patent with publication number "CN218150242U" discloses a foundation pit safety protection device for highway engineering. The utility model moves the device to the outer edge of the foundation pit, arranges it in sequence, and inserts fixed piles into the bottom surface. When the device is hit head-on, the arc-shaped anti-collision plate is hit to drive the connecting rod to open, and the connecting rod drives the slider to compress buffer spring two, and the reaction force of buffer spring two reduces the impact. At the same time, the front base drives the column to compress buffer spring one, which achieves double buffering and effectively reduces the impact.

[0004] In the above patent, the foundation pit can be protected to buffer the impact, but it is difficult to disassemble and replace the baffle when the device is in use. After being hit multiple times, the baffle may be damaged, affecting the use of the device and further affecting the impact buffering effect on the foundation pit. Utility Model Content
