Installation cavity is formed between word beam, several precast slabs, precast slab and I-beam are placed in each installation cavity
Rectangular-shaped plate basis is collectively formed, and the attachment beam of I-beam end is placed at the center on plate basis；The top pile foundation
It is formed with lower part pile foundation by steel reinforcement cage and concreting, the bottom end of steel reinforcement cage and upside in plate basis in the pile foundation of top
Attachment beam be fixedly connected, the attachment beam of downside is fixedly connected in the top of steel reinforcement cage and plate basis in the pile foundation of lower part.
Further, the attachment beam is the steel angle structure with horizontal sides and vertical edge, the horizontal sides and work of attachment beam
Word beam mutually welds.
Further, the precast slab is trapezoidal shape.
Further, it is fixed between the attachment beam and steel reinforcement cage by steel wire lashing.
Further, the top pile foundation is cylindric with lower part pile foundation, and the diameter of top pile foundation is greater than
The diameter of lower part pile foundation.
The utility model has the following beneficial effects:
The utility model has good integrity, is conducive to upper load and uniformly transfers；Bearing capacity is high on soft foundation,
Concrete amount is few, short construction period, and project cost is low；The reliability and economy of work transmission line can be improved.
Detailed description of the invention:
