The installation of petroleum pipeline in construction roadway includes the reinforcement of construction work zone. The reinforcement of construction work zone should be carried out near the side of highway. When cleaning the work zone, compaction treatment should be carried out to ensure the passage of construction machinery and equipment, the loose soil area and the long-term immersion of water. After leveling by machinery, a layer of geotextile is laid on the ground. The geotextile is compacted by manual spreading of 300 mm. Then the geotextile is folded and overlapped on the first layer of soil. Then the wet soil of 200 mm is paved by machinery. Finally, the soil spreading machine is used for rolling.
In order to reduce the amount of construction work, it is necessary to make full use of the existing roads to construct the construction convenience road connecting the working belt and the trunk highway.
The construction roadway should be flat and have enough compressive strength to ensure the safety of construction machinery. The width of the construction roadway is 6 meters, and the turning radius of the turning road is more than 18 meters. The roadway connecting the construction work belt and the highway should be smoothly connected with the main road.
When constructing paddy fields or high underground water level areas, temporary embankments are built on both sides of roads, and drainage ditches are built between roads and embankments. The size of embankments should be determined according to local conditions. Drainage ditches should be connected with the original drainage system. If there is water in the paddy field, the water should be pumped out to the outside of the embankment by a water pump, and the construction of the sidewalk should be carried out after drying.
While building the sidewalk, the return yard and the storage yard should be repaired. For the connecting part between the sidewalk and the highway, effective measures should be taken to protect the highway and the shoulder. If there is a drainage ditch on the roadside, it is necessary to lay a water culvert.
