How many piles per day can the bored pile foundation be 400mm and the pile is 25 meters long?
1 、 impact drilling hole: adapt to relatively soft formation.2, rotating drilling hole: adapt to relatively hard strata or gravel layer, backfill and other complex geological conditions.3. Hole drilling of casing drilling machine: it is suitable for stratum with flowing sand and underground water.4. Drilling by rotary drilling machine5. Drilling under karst geological conditions6, reinforced cage, concrete7 、 deepwater drilling pile fixed platform
The pile can be divided into two kinds of bored pile and dug pile according to the way of hole formation. The digging pile is dug by hand, and the bored pile is made of mechanical hole, according to the mechanical difference. Bored piles are made of underwater concrete, and bored piles can be divided into the following types.
The bored pile foundation is capable of hitting 20 piles with a pile diameter of 25 meters a day and a pile length of 400mm meters
