Complex pile for improving end bearing capacity of bored precast pile

摘要

PURPOSE: A complex pile for improving a bearing force of an end of a bored pile is provided to obtain structural stability by dispersing stress concentrated on a part of a shoe plate of a prestressed high-strength concrete (PHC) pile and preventing the complex pile from being damaged. CONSTITUTION: A complex pile (100) for improving a bearing force of an end of a bored pile comprises a PHC pile (110), a support layer penetrating type insertion pipe (120), and a stress reinforcing unit (130). The support layer penetrating type insertion pipe is fixed to a shoe plate of the PHC pile and penetrates a support layer by penetrating a slime of the bottom of a boring hole. The stress reinforcing unit includes a stress reinforcing rib inserted into the support layer penetrating type insertion pipe in a radial shape. A connection area between the shoe plate of the PHC pile and the support layer penetrating type insertion pipe is enlarged in order to disperse stress.
