Vibrating immersed cast-in-place pile
abstract
Using vibration force, the pile pipe whose lower end temporarily blocks the opening is sunk into the foundation to a predetermined depth, then the reinforcing cage is hoisted into the pile pipe to pour concrete, and then the pile pipe is pulled out by power, and the pile formed by leaving concrete and steel bars underground is called vibration immersed cast-in-place pile.
Vibrating immersed tube cast-in-place pile is suitable for general cohesive soil, silt or muddy soil, sandy soil and artificial fill. The pile length can reach 25m, and the pile diameter can reach 60mm. Vibrating sinking cast-in-place pile has been widely used in general industrial and civil buildings. Compared with the traditional driven reinforced concrete precast pile, it can save 50% steel bars, and the cost can generally be reduced by about 30% under the same bearing capacity.
Advantages and disadvantages:
Advantages: Compared with precast piles, it saves steel, reduces cost and reduces noise pollution. Compared with bored piles,
The construction technology is simple, the speed is fast, and there is no pollution problem.
Disadvantages: it can only be used in soft soil foundation, with small pile diameter and low bearing capacity of single pile.
