Speaking of piling inspection, how do China construction enterprises carry out piling inspection at this stage, and what is the basic situation? The following is the related content of the professional building terminology of piling compiled by Zhong Da Consulting Bianxiao Company, and the basic situation is as follows:

Piling refers to driving a pile into the ground to make the foundation of a building firm. Piling training is an ideal choice for rural surplus labor transfer training, technical training for construction enterprises and re-employment training for laid-off workers. Then, what is the basic situation of how to carry out piling inspection after the piling construction of construction enterprises? Zhong Da Consulting has compiled relevant information, which is basically introduced as follows:

According to the Technical Code for Testing of Building Pile Foundation (JGJ 106-20 14), the main methods of pile foundation testing are static load test, core drilling method, low strain integrity testing, high strain dynamic testing and acoustic wave transmission method.

Piling inspection contents are as follows:

(1) Testing of vertical or horizontal bearing capacity of various piles, piers and pile walls, including testing of bearing capacity of single piles and pile groups;

(2) Detection of bearing capacity and deformation behavior of bearing layer at pier bottom;

(3) structural integrity testing of various piles, piers and pile walls;

(4) Considering the pile-soil interaction or the detection of pile-soil load sharing ratio in composite foundation, the detection of pile-soil stress and strain;

(5) Detection of environmental impacts (such as vibration, noise and soil deformation) during construction;

(6) Other tests under special conditions or in accident handling.

Piling inspection time:

(1) Pre-detection provides a basis for design;

(2) Construction inspection in the construction stage;

(3) Acceptance after completion of construction;

(4) Identification and testing in construction stage or use stage.

Combined with the specific pile driving construction detection, in the pile foundation detection, it is necessary to combine various detection methods, make use of their own characteristics and advantages, and flexibly use various methods according to the actual situation, so as to comprehensively and accurately evaluate the pile foundation.
