With the improvement of the current economic level, the previous dirt roads gradually became concrete roads. At the same time, in the development of current technology, corresponding road paving equipment has also appeared to replace the traditional labor force, and the use of Running Track Paver Machine is not only With these functions, the equipment also has great advantages in the use of ultra-flat floors.
1. Preparation
Debug the Running Track Paver Machine equipment, make two fixed reference level points according to the original level point; lay plastic film, tie the steel mesh, and support the side mold; set up the laser transmitter, lead the floor level to the Running Track according to the original level point Paver Machine.
2. Paving concrete
In the effective range of the Running Track Paver Machine telescopic arm, the concrete is roughly paved by hand first, and then the Running Track Paver Machine completes the vibration, compaction and leveling work at one time.
3. Spread hardened material
When the concrete is initially set (the 3-5mm mark is left on the finger pressure test), first spread 2/3 of the hardened aggregate evenly and vertically to allow the material to fully absorb the water in the concrete and smooth it with a smoothing machine; then Spread the remaining 1/3 amount of hardened aggregate evenly, and smooth it after repeated smoothing; the corner area should be smoothed with a manual spatula and polished.
4. Maintenance and cutting expansion joints
After the construction is completed, curing agent (water plus film, wax, sealing curing agent) can be used for curing; 5-7d after completion, it is advisable to make a cutting seam to prevent irregular cracking. The spacing between the cutting seams should be 6-8m Column distance is determined), the cutting should be unified with elastic threads to ensure that the cutting seam is neat and straight, and the cutting depth should be at least 1/3 of the thickness of the concrete base (cutting expansion joints is generally completed by civil engineering). It can be used normally after 28 days.
5. Other work
1) Flatness test: use F-meter or the same level of measuring equipment for flatness test.
2) Sealing: Before using the floor, fill the cutting joint with filling cement.
The above is that the advantages of Running Track Paver Machine when laying super-flat floors can not only greatly improve work efficiency, reduce the expansion joints of the floor, but also effectively improve the flatness of the ground and prolong the use of the road surface. Longevity and reduced labor costs save enterprises money.
