附件二：土工格栅技术规范
1.
If decided by the Engineer, or shown on the
Drawings, the
Contractor
shall
place
a
prefabricated
plastic
net
(geo-grid)
for
erosion
protection
of
the
slope
after
placing
topsoil
and
seeding
or
incorporated in the topsoil layer of turf or sod.
如工程师指示，在覆盖一层表土和播种后承包商应铺设预制塑料网进行
< br>边坡的侵蚀防护，或并入草皮的表土中
2. Such
mesh shall be of a type and with strength suitable
for
stabilising the slope surface
against slumping and erosion until
vegetation has been established. The
mesh shall be provided by a
reputable
supplier and shall have a proven record from
erosion
protection of similar slopes
and soil materials.
此护网的类型和强度应是适合稳定边坡表面
防止塌落和侵蚀，直至植被
生长出来。护网应该是由有声誉的供应商提供并且应该有类似
边坡和土
壤材料侵蚀防护的证明记录。
size of the mesh openings shall be
maximum 70 x 70 mm. The
