Through over 80 comparative field tests against traditional methods, the company developed a systematic theory, designed testing equipment tailored to China's conditions, and applied for relevant patents.
In 1999, the Jiangsu Provincial Technical Specification for Self-Balancing Pile Bearing Capacity Testing (DB32/T291-1999) was established.
In 2000，the technology received the First Prize for Scientific and Technological Progress in Jiangsu Province.
In 2002, the Ministry of Housing and Urban-Rural Development incorporated it into the Technical Code for Testing of Building Foundation Piles(JGJ106-2003). That same year, the Ministry of Science and Technology designated it as a key project for nationwide promotion and application.
In 2004, the Ministry of Transport incorporated this technology into the specification “Technical Specification of Dynamic Pile tests for Highway Engineering” (JTG/TF81-01-2004).
In 2009, the company compiled the Jiangsu Provincial “Technical specification for static loading test of self-balanced method of foundation pile” (DGJ32/TJ77-2009) and the Ministry of Transport standard “Static loading test of foundation pile - Self-balanced method” (JT/T738-2009).
In 2013, the Ministry of Transport standard “Load cell of static loading test of foundation pile with self-balanced method” (JT/T875—2013) was developed.
In 2017, the Ministry of Housing and Urban-Rural Development standard “Technical specification for static loading test of self-balanced method of building foundation piles” (JGJ/T 403-2017) was developed.
In 2019, compiled the Jiangsu Provincial standard “Technical specification for foundation pile with static load testing of self-balanced method”(DB32/T 3917-2020).
