A novel multifunctional protective fence special for road and bridge green belts comprises a containing plate, the upper side of a first hinged support is rotationally connected with a supporting rod through a pin shaft, a clamping groove is formed in the middle of the upper side of a limiting block, a limiting frame is arranged at the right end of a second hinged support located on the right side, and a spring A is fixedly connected to the interior of a circular groove; through cooperation of the structures, the protective fences on the periphery can be put down through the design of the L-shaped handle and the limiting cam, construction and maintenance of a green belt are extremely convenient, the green belt can be directly constructed and maintained without detouring, the construction efficiency is improved, the workload of workers is reduced, and meanwhile when construction is not conducted or nobody exists, the construction efficiency is improved. The device can be automatically fixed after being lifted, is very convenient, and avoids the situation that pedestrians and the like can easily enter and exit or damage a green belt due to a reserved opening.

Description

technical field [0001] The invention relates to the technical field of road and bridge green protection fences, and more specifically, relates to a new type of special multifunctional protection fence for road and bridge green belts. Background technique [0002] The green belt refers to the strip for greening.

Problems solved by technology

The prior art publication number is CN108797335B, which provides a novel multifunctional protective fence for road, bridge and green belts. The main body beam, the fixed base of the support frame and the support frame body are fixedly contacted and connected through the H-shaped clamping piece, the support frame body is fixedly contacted and connected with the concave connector, and the support frame body and the main beam are connected through the movable contact of the growth rod. The device can be adjusted Although the device has many beneficial effects, there are still the following problems: after the device is fixed by screws, it is necessary to reserve a fixed entrance and exit for the construction and maintenance of the green belt. Not only does the staff need to detour to the entrance and exit, At the same time, due to the reservation of the entrance and exit, pedestrians can easily enter and exit or will damage the green belt. In view of this, we propose a new type of multifunctional protective fence for roads and bridges green belts
