Laying concrete roads requires a series of steps and sound planning. The following is the general concrete road laying process:
1. Design planning: determine the design requirements of the road, including the width, thickness, slope and longitudinal and cross-section of the road. According to the design requirements, determine the required concrete type and proportion.
2. Site preparation: Clear and level the construction site, remove obstructions and weeds. Ensure the safety of the construction site and prepare the required construction equipment and materials.
3. Concrete subgrade construction: According to design requirements, concrete subgrade construction is carried out on the road foundation. Fill and compact the ground sand and gravel first, and then pour and compact the concrete subgrade. Ensure the smoothness and strength of the concrete subgrade.
4. Concreting: laying concrete by the mixer truck on the road base. Before the concrete is poured, the embedded parts are set first, such as road markings, drainage facilities, etc. Then, the concrete is transported to the construction site and poured evenly using tools such as vibrators and finishers.
5. Leveling treatment: Leveling the concrete to ensure the smoothness of the road surface. Concrete can be compacted and shaped using equipment such as pavers and levelers. At the same time, ensure that the slope and lateral slope of the road meet the design requirements.
6. Concrete curing: After concrete pouring, curing is required to ensure the strength and quality of the concrete. The maintenance includes measures such as covering moisture film, moist curing, and regular watering to ensure that the concrete is fully hardened and developed.
7. Pavement process treatment: according to the needs, carry out the smooth treatment, gap treatment, texture treatment and other processes on the road surface to improve the smoothness, adhesion and comfort of the road.
In general, the laying of concrete roads requires steps such as design planning, site preparation, concrete subgrade construction, concrete pouring, leveling treatment, concrete maintenance, and road surface processing. Reasonable construction process and detailed operation can ensure the quality and durability of the road. At the same time, pay attention to construction safety and abide by local construction codes and requirements.
