The invention discloses a quick connecting piece in a foundation static load test. The quick connecting piece comprises a connecting prestressing
tendon and sub-connectors. At least one end of the connecting prestressing
tendon can be in axial locking connection with the sub-connectors. The ends, back on to the connecting prestressing
tendon, of the sub-connectors are provided with positioning holes, the
diameter of the positioning holes can be decreased, the positioning holes are provided with adjusting pieces, and the
diameter of the positioning holes can be adjusted through the adjusting pieces. The quick connecting piece can be in quickly detachable connection with a
pile foundation
rebar through the sub-connectors connected to one end of the prestressing tendon, the connecting speed is high, the junction between the
rebar and the sub-connectors is convenient to adjust, and therefore it is guaranteed that the
rebar on the top of a
pile is stressed evenly. Furthermore, as the quick connecting piece is convenient to connect, high-lift operation can be avoided, work difficulty and work risks are lowered, materials are saved, material waste is avoided, repeated testing can be achieved, and the success probability of testing can be enhanced.
