Why build concrete walkways?
Concrete walkways are very common in modern urban construction. Compared with roads made of bricks and natural stone, concrete walkways are cheaper and easier to install, so the construction of concrete walkways is becoming more and more popular.
How to make a concrete sidewalk?
There are several steps in concrete sidewalk construction:
1. Before building concrete walkways, we should prepare a level ground condition. Therefore, the original sod and excess soil should be removed according to the situation on the site. In addition, if conditions permit, the original road soil can be dug up and filled with gravel or other types of soil, and the road can be compacted with vibratory plate compactors and vibratory rollers to prepare a more solid foundation.
2. Sprinkle water on the prepared roadbed and wet the gravel base.
3. Arrange the concrete in the required proportions and then mix it evenly. Spread the concrete onto the road formwork.
4. Use concrete power screeds to remove the air from the concrete, scrape the concrete floor and enhance the density of the concrete.
Use vibratory plate compactors or Vibratory Rollers to compact the surface concrete onto the pavement.
5. Sprinkle 2 mm of dry sand ash on the surface of the concrete, and wait for the dry sand ash to become wet after absorbing water. Then the use of power trowels on the concrete surface of the last construction, makes the surface more smooth, and improves the concrete surface compactness and wear resistance.
6. If you need to cut the road surface, you can use concrete saws to cut the road surface as required. Finally, wait for the initial solidification of concrete, and then carry out sprinkler curing.
Tools needed for concrete walkway construction
Concrete Screeds
Concrete screeds can be used to discharge the air in concrete, scrape the concrete ground, enhance the density of concrete, and concrete ground vibration leveling. The main characteristic of the machine is its lightweight. We can operate alone, this machine is suitable for direct construction on the concrete surface, the use of aluminum plate high strength flatness, under high-frequency vibration to achieve concrete flattening and compaction. At the same time complete the pulp lifting process. Then we can achieve the purpose of multi-purpose of one machine.
Power Trowels
Power trowels are used for cement concrete surface construction of pulp, and smoothing equipment. The surface of the machine construction is smoother and flatter than the manual construction, which can greatly improve the compactness and wear resistance of the concrete surface, and greatly improve the work efficiency compared with the manual operation in efficacy. Power trowels can be widely used in high-standard plants, warehouses, parking lots, squares, airports, and frame-type building concrete surface pulping, smoothing, and soothing. It is the first choice in concrete construction.
Concrete Saws
Concrete saws are a tool for road maintenance and construction. Its main function is to cut seams on the road surface. The cutting depth can reach 100 mm to 400 mm. The mechanical structure is simple, lightweight, high production efficiency, easy to use, and low price. It is often used for cutting concrete, cement, and stone. The machine is widely used in highway construction, municipal engineering, cement products, construction engineering, stone factories and mines, and other industries.
