The blocking block is usually arranged between the corrugated guardrails, which can effectively absorb and disperse the energy when the vehicle hits, reducing the damage to the vehicle and passengers. With the rapid development of expressway construction in China, the total length of the open expressway has reached 177,300 kilometers, and the total mileage of the open road has reached 5,354,800 kilometers. However, in the long-term operation of the expressway, especially for those open to traffic for more than 10 years, i.e. before 2014, due to the experience of multiple maintenance and road surface major and medium repair projects, the road surface elevation gradually exceeds the original design elevation, which leads to the height of the original traffic safety facilities no longer meeting the specification requirements.

[0003] In these sections, the maintenance of the guardrail has become a problem to be solved. In order to cope with the challenge of road elevation change, the wave-shaped guardrail in the roadbed section currently mainly adopts the method of overall removal of the original guardrail and new construction of the same grade guardrail that meets the current specification requirements. However, this overall replacement method has very high investment in time, labor and economic cost, and the wave-shaped plate has low recycling rate, causing waste of resources.

On the one hand, the process of overall removal and new construction of the guardrail is complicated and requires a large amount of manpower and time investment, which seriously affects the efficiency of maintenance work. On the other hand, due to the low recycling rate of the wave-shaped plate, the replacement cost is high, which brings heavy economic burden to the expressway management department.

[0005] Therefore, in view of the deficiencies in the prior art, especially in view of the low efficiency, high cost and resource waste problems in the maintenance of expressway guardrails, we urgently need a convenient to dismouting's expressway is with preventing blocking mechanism. This blocking mechanism should be able to significantly improve the efficiency and quality of guardrail maintenance, reduce maintenance cost, and ensure the safety and smoothness of expressway traffic, providing strong support for the sustainable development of expressway.
