Description

A protective fence for road and bridge engineering

Technical Field

The utility model belongs to the technical field of protective fences, in particular to a protective fence for road and bridge engineering.

Background technique

Roads and bridges are generally composed of several major parts, such as roadbed, pavement, bridges, tunnel projects and traffic engineering facilities. With the vigorous development of the transportation industry, the number of high-grade highways, mainly expressways and first-class highways, has increased year by year. my country's highway industry has begun to enter a new stage with the construction of high-grade highways as the focus. High-grade highways should pay special attention to the design of the line shape, maintain the continuity of the line shape, and make passengers feel safe and comfortable physically and psychologically. At present, protective fences are installed in road and bridge projects to play a role of isolation.

After searching, the patent announcement number CN209428984U discloses a road and bridge engineering protection device, including a walking device, a fixed support device, a connecting device, a protection frame and a support rod device. The two ends of the two sides of the protection frame are fixedly installed with connecting devices, and the top of the rear side of the protection frame is fixedly installed with two sets of equidistant support rod devices, and the two ends of the bottom of the protection frame are fixedly installed with walking devices. The utility model is provided with a supporting device, through which the rear side of the road and bridge engineering protection device can be fixedly supported to prevent the road and bridge engineering protection device from collapsing and ensure the protective safety performance of the road and bridge engineering protection device. The road and bridge engineering protection device is provided with a connecting device, and the road and bridge engineering protection device can be connected by connecting multiple groups, which is convenient for the installation and disassembly of the road and bridge engineering protection device, and is convenient and quick to use, saving time and improving work efficiency.

When the existing protective fences for road and bridge projects are actually used, when a vehicle on the road or bridge collides with the protective fence, the vehicle is likely to knock down the protective fence. At this time, the vehicle is likely to fall off the bridge, causing a major safety accident. The safety is low, and when the vehicle collides with the protective fence, it will cause great damage to the vehicle. For this reason, we propose a protective fence for road and bridge projects to solve the existing problems.
