With the artificial turf industry increasingly popular in the market, do the lawn of the team is growing, there are a lot of manufacturers are labor and materials, buyers need only the final acceptance results on it. But also because more and more manufacturers, many of the Chamber of Commerce to purchase artificial turf quality problems to worry about, or a problem with the laying of the venue, etc., so in order to allow customers to dispel doubts and concerns in mind, as a manufacturer of artificial turf teach you some acceptance standard, hopes to buyers in the purchase and laying of artificial turf field to have some help.
First, the basis of acceptance of artificial turf
A, the general basis of cast cement concrete or asphalt, has a certain strength and stability.
B, foundation cracks and not peeling or arising from the frozen sand.
C, based flatness error is less than 3 m ruler 4mm, with a certain slope, typically 3-5%, in order to rain drainage.
D, in the frozen area, freezing technique should be used, generally between the asphalt layer and gravel layer, add a layer of geotextile to buffer the water along the base of the trench should be special water treatment.
E, the surface should be kept clean and dry basis, should ensure that the asphalt base after completion of the maintenance period is about 30 days, so that the asphalt surface of the low-boiling components evaporate, ensuring the basis of the surface layer has sufficient bond strength.
F, concrete foundation must also have 30 days or so of the maintenance period, a large area to be considered reserved for expansion joints, smooth surface to be processed.
G, asphalt concrete foundation Specifications
a, rolling basis after the density is greater than 95%
b, graded gravel subgrade layer compacted density of 2.3kg / cm2 or more, the surface smooth, solid and no sand pit, plum phenomenon.
c, the asphalt surface layer should be no oil, no cracks, no pressure joints, no water blocking water phenomenon.
Second, the acceptance procedure
a, first check the site flatness and slope of the failed part to be amended.
b, control data inspection and acceptance, completion data provided by the construction unit.
c, preparation of construction plan, the audit report to the owners.
d, according to the amount of the preparation of materials engineering programs to ensure construction quality and schedule.
e, clean up the site, laying on the lawn of the site need to clean up, remove oil, debris, dirt and other junk.
f, the venue four weeks should be kept clean, non-garbage admission.
g, for a long time to build the old site, you must clean up the joints, fill with new material.
