产品详情资料
 应填充混凝土，费用由承包商承担。深度应小心
选中的。在斜坡地面上，必须在斜坡杆侧开挖
整个设计深度。
d、 如果遇到岩石，施工工程师应检查开挖是否
达到要求的种植深度。
e、 对于砂和泥炭中的开挖，应提供模板，并继续向下
如果不开挖，开挖就会塌方。
f、 水淹地区的挖掘与普通土壤一样。但为了保持水
应使用足够低的吸入泵。
g、 在人口稠密地区，应在以下位置提供公共安全警示带和标志
挖掘坑。
10.5回填
a、 对于电杆基础，预计回填量小。回填应为
在支柱周围进行，并在固化后支撑锚基础。回填应免费
从各种盐、杂草和其他类似的有机物质中提取。与混合
允许使用砾石。对于岩坑，应混合20%-30%的土壤和沙子以减少
并确保回填更加密实。
b、 回填土应夯实至与周围土壤相等的干密度。回填
应在电杆和拉线周围做好护坡并夯实。回填土应夯实
好使用机械压实机。回填应铲回150mm层。
10.6混凝土
a ation shall be made with backhoe. Where the soil permits excavation shall
done with an auger, power compressor or by hand so that the soil disturbance should be
minimum. If excavation has been done by using backhoe, the entire surrounding area of
pit shall be filled with concrete at contractor's cost. The depth should be carefully
checked. On sloping grounds excavation on pole side of the slope must be taken out to
the full design depth.
d. Where rock is encountered, Construction Engineer should check that the excavation is
up to the required planting depth.
e. For excavation in sand and peat, shuttering should be provided and continued down with
excavation, if it is not done, the excavation will cave in.
f. Excavation in waterlogged areas is done as in ordinary soil. But in order to keep water
sufficiently low, suction pumps are to be used.
g. In populated areas, for public safety warning tapes and signs shall be provided where
excavating pits.
10.5 Backfilling
a. Backfilling is expected to be minimum in case of pole foundation. Backfilling shall be
done around the pole and stay anchor foundation after curing. Backfilling shall be free
from all sorts of salts, grass weeds and other similar organic material. Mixing with
gravel is allowed. For rock pits, 20% - 30% of soil and sand shall be mixed to diminish
void and to ensure that back filling is more compact.
b. The backfill shall be tamped to a dry density equal to the surrounding soil. The backfill
shall be well banked and tamped around pole and stays. The backfill shall be rammed
preferably with mechanic compactor. Back fill shall be shovelled back in 150mm layers.
10.6 Concrete
a. Cement shall be type 1 and in areas having water logging and salinity, Sulphate resistant
cement type 5 may be used. SEC Engineer shall direct t r impurities.
