[0002] In highway engineering, culverts are common underground drainage facilities, and their transportation and installation processes directly affect the project progress and quality. Traditional culvert transportation methods have some limitations and deficiencies, especially in terms of stability, safety, and operation convenience.

[0003] Firstly, during transportation, due to uneven road surfaces or sharp vehicle turns, culverts are prone to rolling or displacement, which may not only cause damage to the culverts but also pose safety hazards to surrounding personnel and equipment.

[0004] Secondly, traditional culvert transportation devices often lack effective fixing and positioning mechanisms, resulting in the need for additional manpower and time to ensure the correct placement of culverts during loading and unloading. This not only increases the labor intensity but also reduces the operation efficiency. In addition, culverts vary in size and weight, and traditional transportation devices are difficult to adapt to the transportation requirements of different specifications of culverts, limiting their application scope and flexibility. Therefore, we provide a culvert transportation device for highway engineering. Content of the Utility Model
