Cap tower-crane foundation of concrete cast-in-place high pile for tower erection at the house center

The utility model relates to a cap tower-crane foundation of concrete cast-in-place high piles for tower erection at the house center, which is characterized by mainly comprising four support piles, a reinforced concrete cap supported by the support piles, and sealed steel hoops embedded in the support piles. The support piles are concrete cast-in-place support piles. The cap tower-crane foundation has the advantages that compared with a steel platform tower-crane foundation and a steel-tube high pile tower-crane foundation the cap tower-crane foundation has small steel quantity and evidently lower construction cost than steel structures with same height; the cap tower-crane foundation of concrete cast-in-place high piles adopts conventional construction process, thereby having small construction difficulty, easily guaranteed quality and simple and quick construction; final-period removal of the tower-crane foundation is easier than that of the steel-tube concrete pile; the bearing capacity meets safety requirements; and the cap tower-crane foundation has the evident advantages of low construction cost, simple construction and short construction period.
