Deep hole pile foundation bearing capacity testing device
The invention discloses a deep hole pile foundation bearing capacity testing device. The problem that friction force of a soil body on the sidewall of a sleeve influences testing of the bearing capacity of a pile foundation is solved. The testing device comprises an inner sleeve (3) arranged at the upper end of the outer side face of a pile body (1). Annular supporting ribs (5) are arranged on the outer sidewall of the inner sleeve (3) at intervals. The inner sleeve (3) provided with the annular supporting ribs (5) is sleeved with an outer sleeve (2). Gaps (11) are formed between the inner sidewall of the outer sleeve (2) and the outer side ends of the annular supporting ribs (5). A sealing ring (4) is arranged between the bottom end of the inner sleeve (3) and the outer sleeve (2). A cavity between the inner sleeve (3) and the outer sleeve (2) is filled with water (10). A jack (7) and a balancing weight (8) are arranged on the top end face of the pile body (1). By adopting the testing device, valuable reference parameters can be provided for construction of cast-in-place piles of the same type.
