预制基础：采用C30混凝土，尺寸2*2*0.5m。基础柱间间距6-10米.预制基础棱角采用角钢L50*50*5封边，在顶部预埋2个HPB235φ20钢筋预埋环，并在角钢上涂刷防锈漆。中间预留两根DN100钢管用于吊装孔。混凝土垫块需要埋十字形的扁钢，用于焊接挡块以固定柱子底板。吊装孔和预留扁铁位置浇筑时按现场实际确定。考虑增加至少20个基础机动使用。现场需要按此规格预制基础的数量最少达424个。

Prefabricated foundation: Made of C30 concrete, with a size of 2 * 2 * 0.5m. The spacing between foundation columns is 6-10 meters. Prefabricated foundation edges are sealed with angle steel L50 * 50 * 5, and 2 HPB235 are embedded at the top φ 20 steel bars are pre embedded with rings and anti rust paint is applied to the angle steel. Two DN100 steel pipes are reserved in the middle for lifting holes. The concrete cushion block needs to be embedded with a cross shaped flat steel for welding the block to fix the column base plate. The pouring of lifting holes and reserved flat iron positions shall be determined according to the actual situation on site. Consider increasing the use of at least 20 basic maneuvers. The minimum number of prefabricated foundations required on site according to this specification is 424.

Precast foundation: C30 concrete, size 2 * 2 * 0.5m.. The spacing between foundation columns is 6-10m. Angle steel L50*50*5 is used for edge sealing of prefabricated foundation corners, two embedded rings of HPB235φ20 steel bars are embedded at the top, and antirust paint is painted on the angle steel. Two DN100 steel pipes are reserved in the middle for hoisting holes. The concrete cushion block needs to be buried with cross-shaped flat steel, which is used to weld the stop to fix the bottom plate of the column. When casting the lifting hole and reserved flat iron position, it shall be determined according to the actual situation on site. Consider adding at least 20 basic maneuvers. At least 424 foundations need to be prefabricated on site according to this specification.
