Portable fence for highway maintenance

Abstract

The invention discloses a portable fence for highway maintenance. The fence comprises a first side bar, a first connecting rod, a second connecting rod and a second side bar; a plurality of folding railings uniformly distributed are arranged between the first side bar and the first connecting rod and between the second connecting rod and the second side bar in an intersection mode, and the foldingrailings are rotatably connected through connecting nails; and storage brackets are installed on the side walls of one sides of the first side bar, the first connecting rod, the second connecting rodand the second side bar, and the interior of each of the storage brackets is provided with two rotating shafts. The portable fence convenient to carry for the highway maintenance has the beneficial effects that by designing the folding railings, the fence can be folded and stored as a whole, the space is not occupied, the packaging and the transport are convenient, and sturdiness and durability are achieved; through holes are formed in the folding railings to reduce the overall weight without affecting the structural stability, the texture is light, the carry is convenient, the transportationcost can be greatly reduced, the cost is low, the cleaning is convenient, and no extra maintenance is required.

Description

technical field [0001] The invention belongs to the technical field of traffic safety management, and in particular relates to a portable fence for road maintenance. Background technique [0002] It is an operation to keep the road in good condition, prevent its quality from deteriorating, and provide good service to road users. After the highway is completed and opened to traffic, due to the wear and impact of the wheels, the erosion and weathering of natural forces such as heavy rain, floods, sandstorms, ice and snow, sun exposure, and ice melting, as well as man-made damage and some defects left over from construction, the quality of the road will be affected. will gradually decrease. Therefore, after the highway is completed and opened to traffic, maintenance and repair measures must be taken, and continuous updating and improvement must be carried out. Road maintenance must repair the damaged part in time, otherwise it will lead to increased investment in repair proje...
