Abstract
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...
