| Assembly of grass tile |
| 1. Prepare
turf |
| 2. Level the
foundation; grass tile needs a stable base layer and when pieces
of grass tile are to be laid on fire-fighting accesses, the
base layer for grass tile shall be designed and constructed
according to relevant design and construction specifications
for fire-fighting roads. When grass tile is used in parking
lots, it can be directly placed on a tamped foundation, and
sometimes, additional drainage facilities need to be set on
locations with relative big moisture so as to stabilize the
foundation. Layers of miry soil or other types of soft soil
(including backfill layers) may lead to the inclination of the
grass tile and in such cases, 50% gravel or coarse sand can
be added to the soil and then tamped to give a reinforcement
treatment (the degree of compaction shall exceed 85%). This
can not only stabilize the foundation, but also promote the
growth of grass roots. |
| 3. Lay grass
tile After the foundation is well prepared, dust some organic
fertilizer over its surface, and then place pieces of grass
tile directly on the prepared foundation, bearing in mind that
the top of these pieces of grass tile shall be level with the
surrounding road surface or terrace. The method for splicing
pieces of grass tile is as follows: lay pieces of grass tile
to form the first row of grass tile, with their sides with agraffe
holes placed on the starting side of the row, and then lay the
second row of grass tile by hooking pieces of grass tile onto
the first row of grass tile. And then, repeat the procedure
until all the area is covered. As to curved corners or other
places with a strange shape, properly cut pieces of grass tile
can be used to fill them, as pieces of grass tile can be cut
with an electric or hand saw in order to produce any shapes
that may be required by the actual situation. |
| 4. Place turf
When turf is about 25mm thick, it can be implanted into grass
tile directly; when it is greater than 25mm, the thickness should
be reduced properly before turf is implanted into the cellular
units. Turf is then implanted into grass tile through tamping
with any means other than vibration machinery, which, if used,
may cause the soil on grass roots to drop. |
| 5. Water grass
tile until the grass take root. |
