[0032] The traffic engineering guardrail can accumulate and stack the shell 1 by directing the sliding cover 2 towards the bottom surface during transportation, thereby reducing the occupied space and improving the transportation efficiency, so that more shell 1 can be transported at one time. During construction, the workers can directly sit on the unopened shell 1 for a short rest when they feel tired, thereby providing convenience for the construction personnel. After the shell 1 is transported to the destination, the worker removes the sliding cover 2, and the force relieving assembly is ejected from the shell 1. The force relieving assembly is rotated to be parallel to the ground, and the force relieving assemblies in two adjacent shell 1 are spliced. The shell 1 can be spliced according to the actual needs to assemble the guardrail with different lengths. After the guardrail is spliced, the warning strip is attached to the warning assembly to warn the oncoming vehicles.

[0033] As shown in Figure 2 , Figure 3 , Figure 4 , the force relieving assembly comprises an ejection plate 4 movably installed in the shell 1. The side of the ejection plate 4 away from the shell 1 is provided with a rotating plate 5.
