Description

Technical Field

[0001] The utility model relates to the field of temporary road design, in particular to a temporary road suitable for a project construction period. Background Art

[0002] Many new energy projects, especially temporary roads of wind power projects, sometimes encounter silty soil, slurry, and cultivated land and farmland. The slurry sections need to be replaced, which requires a large amount of stone. In addition, it is inevitable to occupy cultivated land and farmland. The occupation of general cultivated land and farmland also has certain restrictions, and it is necessary to formulate plans such as reclamation and topsoil stripping. There are also certain difficulties in handling soil and water conservation procedures. The existing temporary roads are generally built during the construction process. A temporary gravel road is first built, and the original appearance is immediately restored after the construction of the wind turbine foundation and the transportation and lifting of large equipment are completed. The construction of temporary roads also requires a large amount of stone, and a large amount of machinery is required to handle it during the restoration. In fact, it also causes certain damage to the cultivated layer and costs a lot of money.

[0003] Passing through cultivated land and farmland is a common problem in almost every new energy project, especially in road planning, which is often unavoidable. As the country pays more attention to cultivated land and farmland, the requirements for soil and water conservation procedures in projects are becoming more and more stringent. The existing temporary roads require a lot of stone materials, and the construction speed is slow and time-consuming. A large amount of machinery is needed to handle the restoration, and it also costs a lot of money. Utility Model Content
