Abstract

The invention relates to the technical field of construction, in particular to a single-pile vertical pressure-resistance static load test detecting device. The device comprises a precast pile, a jack, a damping precast piece and a pressure-resistance precast piece; the precast pile is embedded in the ground, and is perpendicular to the horizontal plane; the jack is arranged on the top surface ofthe precast pile; a cushion plate in the damping precast piece is put right above the jack; and two fixed parts in the damping precast piece are fixedly connected with a main beam. The device reducesthe use number of pressing blocks to simplify the test; through design of the main beam and an H-shaped beam, the weights of the main beam and the H-shaped beam can be applied to the test; and meanwhile, the overall gravity center is lowered to further improve the safety. The confining pressure of pile top concrete in axial pressure resistance is increased, so that the pressure resisting strengthof the pile top concrete is improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a single pile vertical anti-compression static load test detection device. Background technique [0002] The inspection and acceptance of engineering piles in construction projects generally has two aspects: the integrity of the pile body and the inspection of bearing capacity, among which the vertical compressive bearing capacity test of a single pile is an important content in the inspection of bearing capacity. In the single pile static load test, the load acting on the pile is generally provided by the reaction device. The ease of use of the reaction device directly affects the process and results of the test. Commonly used are surcharged reaction beam device and anchor pile reaction beam device. [0003] The current domestic publication number is CN106320402B, which discloses a vertical static load test device for engineering piles, including main beams, secondary beam...
