[0029] 1. The column adopts a split structure, and each component can be manufactured separately, which is low in manufacturing difficulty and convenient for on-site construction. During assembly, the T-shaped notch of the split column is first sleeved with the T-shaped hollow pipe of the adapter seat, so that one adapter seat connects two split columns. Then, the limiting rod is inserted through the horizontal through hole and the limiting through hole in sequence, so that the magnet is adsorbed with the adapter seat, the limiting plate is limited from freely moving, and the limiting plate is connected to the two split columns through the limiting rod. As a result, the T-shaped hollow pipe cannot be pulled out of the T-shaped notch, and the split column and the adapter seat cannot be freely separated, so that the column is connected into a whole, the height of the column can be flexibly adjusted on site, the protection height of the fence is changed, different road protection requirements are met, the adaptability is high, the problem of fixed height of the column before leaving the factory in the prior art is solved, and the operation is simple. The screw connection mode is replaced, which is labor-saving and fast.

[0030] 2. The fence and posts are easy to assemble. Simply insert the hooks into the hanging holes for quick positioning. The fence will not fall off freely, ensuring reliable installation. This method replaces screw connections and allows for faster construction. After installation, the fence prevents the limit plate from shifting laterally, thus preventing the limit plate from separating from the connecting seat. This improves the installation stability of the limit plate, creating mutual restraint and making the overall structure more stable.

[0031] 3. The cargo box is restricted from separating freely from the base and the column by inserting rods, and the column is restricted from separating the cargo box from the base by inserting rods. They restrain each other to form a stable structure that is not easy to fall apart and has high reliability. The base is simultaneously subjected to the pressure of the cargo boxes on both sides, thus preventing the column from tipping over freely. This solves the problem of not having anchor bolts for on-site fixation of the column in the middle area.

[0032] 4. The fence restricts the free sliding of the crash barriers through the support components. The crash barriers are neatly arranged, providing good protection and facilitating construction. The crash barriers protect the fence, withstanding direct impacts from vehicles, reducing the impact force on the fence, and making the fence less prone to damage. Attached Figure Description
