Definitions
- the present invention relate to a cast-in-place pile and the construction process for manufacturing of the cast-in-place pile.
- One of the objectives of the invention is to provide the new type of cast-in-place piles which will efficiently increase the bearing capacity of a single pile without increasing materials to obtain better economic results.
- Another objective of the invention is to provide a new type of cast-in-place pile group which is formed by the rigid connection of the cast-in-place piles of the invention with pre-embedded parts to form the diaphragm wall.
- Borehole of flower shape which is formed by a central hole intersected by three or four outer smaller holes;
- the conventional multi-shaft long auger drilling rig can be used for drilling non-cylindrical boreholes.
- the rig has four augers, four shafts, and the central ones are greater than outers.
