Legal basis: Measures for the Administration of Rural Highway Construction

Article 3 The construction of rural highways shall follow the principles of leading the country, grading responsibility, safety first, ensuring quality, ecological and environmental protection, and adapting measures to local conditions.

Article 40 After the completion of a rural highway construction project, it shall be handed over and accepted for completion in accordance with the relevant provisions of the State. If it has not been accepted or the acceptance is unqualified, it shall not be delivered. Generally, the delivery and completion acceptance of rural highway construction projects can be combined, and multiple projects can be accepted together.

Article 41 Rural highway construction projects shall be handed over for acceptance by the project owner, and the local transportation authorities at or above the county level shall organize the completion and acceptance in accordance with the project management authority. The project of combined delivery and completion acceptance shall be accepted by the local transportation department at or above the county level in accordance with the project management authority. Rural highway construction projects organized and accepted by the local transportation departments at or above the county level shall invite relevant departments such as public security and production safety supervision and management at the same level to participate, and the acceptance results shall be reported to the competent departments of transportation at the next higher level for the record.

The local transportation authorities at or above the municipal level shall take the acceptance of the project as an important part of the supervision and inspection.

Article 42 When accepting a rural highway construction project, the acceptance unit shall, in accordance with the design documents and the project contract, organize quality appraisal and testing, and approve the quantity of the project.

Article 43 If a rural highway construction project is found to have quality defects and other problems during delivery and acceptance, the construction unit shall complete the rectification within a time limit.

Article 44 After the new rural highway project is handed over and accepted, it can be opened to traffic and handed over to the management and maintenance unit. The competent departments of transportation at or above the county level shall promptly organize and do a good job of basic data statistics, updates and archiving of construction data.

Article 45 The provincial-level competent departments of transportation may, in accordance with the measures for the acceptance of the completion (delivery) of highway projects and the standards for the inspection and evaluation of highway engineering quality, and in combination with the actual situation of the region, stipulate specific acceptance procedures for rural highway construction projects.

Legal analysis: The local government at or above the county level shall, in accordance with the principle of ensuring the safety of highway operation and saving pure land and the needs of highway development, organize the Ministry of Transportation, Land and Resources to delineate the scope of highway construction control areas.

Legal basis: "Regulations on the Protection of Highway Safety" Article 10 Hong Li Draft The local people at or above the county level shall, in accordance with the principle of ensuring the safety of highway operation and saving land and the needs of highway development, organize the departments of transportation, land and resources and other departments to delineate the scope of highway construction control areas.

The scope of the highway construction control area, the distance from the outer edge of the highway land to the outward is as follows:

1) National highway not less than 20 meters;

2) Provincial roads not less than 15 meters;

3) The county road is not less than 10 meters;

4) The village road is not less than 5 meters.

If it belongs to the expressway, the scope of the highway construction control area shall be circled from the outer edge of the highway land to the distance from the standard cavity shall not be less than 30 meters.

The scope of the building control area on the inside of highway curves, interchanges and level intersections shall be determined according to the requirements of safe sight distance.

Summary. 1. The route design should be combined with the topography, geomorphology, geology and hydrological conditions along the line, according to the project cost, social environment and other factors for route plan comparison and technical and economic demonstration, reasonable use of technical indicators, comprehensive consideration of flat, vertical and horizontal three aspects of the elements, to ensure that the line is continuous, balanced, and driving safety.

1. The route design should be based on the bright terrain, geomorphology, geology and hydrological conditions along the land and field cooperation, and the route plan comparison and technical and economic demonstration should be carried out according to the project cost, the environment of the social and social meeting, and the technical indicators should be reasonably used, and the three elements of flat, vertical and horizontal should be comprehensively considered to ensure the continuity and balance of the alignment and the safety of driving.

2. Implement the principle of protecting cultivated land and saving land; Fewer house demolitions and fewer relocation of utility pipelines; Make full use of old roads, safely use the original bridges and tunnels, avoid major changes or large filling and excavation, and prevent the induction of new geological diseases; It is convenient for farmers (herdsmen) to travel, and serves the town; Attention should be paid to the harmony with the terrain, features, environment and landscape along the line, and the protection of the natural ecological environment and cultural relics and historic sites. Tachibana.

3. Try to avoid landslides, debris flows, soft soils, swamps and other geological poor areas and special areas such as deserts and permafrost. When it is necessary to cross, the crossing area should be narrowed, and necessary engineering and technical treatment measures should be taken.

The width of the roadbed (including the width of the lane and shoulder) should be strictly implemented in accordance with the provisions of the "Technical Standards for Highway Engineering", among which, the width of the two-lane pavement in the restricted section should not be less than 5m, and the width of the single-lane pavement should not be less than 3m. If a single-lane pavement is used, the width of the shoulder on one side shall not be less than. Single-lane roads should be staggered within an appropriate distance.

The wrong lane should be located in a favorable place where the driver can see the vehicles coming between the two adjacent wrong lanes, and the width of the roadbed should not be less than 20m, and the effective length should not be less than 20m. In continuous long and steep downhill sections, avoidance lanes should be set up where the safety of traffic is endangered. The maximum longitudinal slope in the general area of the restricted road section should not be greater than 10%, and the maximum longitudinal slope should not be greater than 8% in the area above 2000m above sea level or in the snow and ice area.

When the maximum longitudinal slope is adopted, the maximum slope length should not be greater than the provisions of the "Highway Engineering Technical Standards".

The restricted road section is equipped with an ultra-high flat curve, and its composite slope value should not exceed 11% (except for areas above 2000m above sea level or snow and ice). The technical rock ruler knowledge indicators such as stopping sight distance, meeting sight distance, minimum circular curve radius, minimum slope length, maximum slope length of different longitudinal slopes, and minimum radius of vertical curve of restricted road sections can be appropriately reduced after technical and economic demonstration. However, there should be no combination of unfavorable factors, and traffic safety facilities should be set up to ensure driving safety.

When the difficult and restricted road section adopts the turning curve, the technical indicators should refer to the relevant provisions of the "Technical Standards for Highway Engineering" (JTJ-97), reasonably determined by technical and economic demonstration, and should be roughly set up traffic safety facilities and necessary speed limit signs.

Summary. For rural roads, the width of the roadbed is generally not less than meters, and the width of the road surface is not less than meters.

For rural roads, the width of the roadbed is generally not less than meters, and the width of the road surface is not less than meters.

What is the legal basis? In principle, the rural highway construction standards shall be implemented in accordance with the Technical Standards for Highway Engineering (JTGB01-2003).
