Abstract

The invention relates to pile foundation detection equipment and a detection method using the equipment. The pile foundation detection equipment comprises a coring machine, a rack is arranged beside the coring machine, the rack and the coring machine are both fixedly connected with the ground, a gradienter is fixedly arranged on the rack, the rack comprises an adjusting assembly used for adjustingthe top face of the rack to be horizontal, a fixed cylinder is arranged on the rack in a rotating mode, the fixed cylinder annularly sleeves the circumferential outer wall of a drill rod of the coring machine, the fixed cylinder rotates relative to the rack by taking the vertical center line of the drill rod as a rotating shaft, and a detection assembly for detecting whether the drill rod is always vertical or not is arranged in the fixed cylinder. The equipment has the effect of improving the integrity of a drill core.

Description

technical field [0001] The present application relates to the field of concrete pile foundation detection, in particular to a pile foundation detection equipment and a detection method using the equipment. Background technique [0002] At present, the main methods of pile foundation detection include static load test, core drilling method, low strain method, high strain method and acoustic transmission method, among which the core drilling method has the characteristics of science, intuition and practicality, and is widely used in the detection of concrete pouring piles; A complete and successful core drilling inspection can obtain the pile length, pile concrete strength, pile bottom sediment thickness and pile integrity, and can judge and identify the geotechnical characteristics of the bearing layer at the loading end. [0003] In the related art, when coring a pile foundation, the location of the coring is positioned to avoid the position of the steel cage, and the core s...
