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。

c、 砂的平均粒径为0.35至0.50 mm，含泥量不得超过
5%以上。
d、 天然砾石或人造碎石的尺寸应根据
到坡度。可以使用粒度为10至40mm的碎石。骨料应
符合ASTM A23.1。混凝土的小强度应为M20（210Kg/cm²）。
砾石中的含泥量不得超过2%，否则含泥砾石
应该用水清洗。
e、 砂、粗骨料和水泥应按照设计配比
设计部门批准的混合料。预拌材料的测量
混凝土应符合预拌混凝土规范ASTM C 94
每立方米混凝土的小水泥含量不得小于250kg。
混凝土的成分应均匀，并在整个混合过程中保持一致
一批浇筑时的混凝土温度不得超过38°C
温和天气低于2°C。
f、 如果使用模板，这些模板应足够紧密，以防止砂浆损失
混凝土，并应严格保持到位，直到混凝土足够硬化
以防止因拆卸而损坏。
g、 如果基坑未开挖，承包商应仅支付SEC批准的基础尺寸

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

c. The average grain size of sand is 0.35 to 0.50 mm and the mud content shall not be more
than 5%.
d. The size for natural gravel or the artificial crushed stone shall be determined according
to the grading. Crushed stone of 10 to 40mm grain can be used. The aggregate shall
conform to ASTM A23.1. Concrete shall be of minimum strength M20 (210Kg/cm²).
Mud content in gravel shall not be more than 2% otherwise the gravel containing mud
should be washed with water.
e. The sand, coarse aggregate and cement shall be proportioned according to the design
mix approved by the design department. The measurement of material for ready mix
concrete shall conform to specification for ready mix concrete ASTM C 94. The
minimum cement content per cubic meter of concrete shall not be less than 250kg.

The concrete shall be uniform in composition and consistent through out the mixed
batch. Concrete temperature when being placed shall be not more than 38 °C and not
less than 2 °C in moderate weather.
f. Where forms to be used, these shall be sufficiently tight to prevent loss of mortar from
concrete and shall be maintained rigidly in position until concrete has hardened enough
to prevent damage by the removal.
g. The contractor shall be paid only for SEC approved foundation size, if the pit not dug
with auger and mor
