Rongchuang Geotechnical was invited to participate in the compilation of the "Green Technology Code for Foundation Pit Engineering," jointly chief-edited by East China Jiaotong University, Tianjin University, Shanghai Construction Group Co., Ltd., and Shenzhen University. After three years of twists and turns due to the pandemic, and with the joint efforts of more than a hundred industry leaders, experts, and scholars, it was successfully issued and implemented this year.

The "Green Technology Code for Foundation Pit Engineering" is a set of technical regulations for foundation pit engineering that are green, environmentally friendly, safe, and efficient, summarized and compiled after thorough investigation of foundation pit engineering technologies in recent years. It basically reflects the latest research results of green, low-carbon, energy-saving, and environmentally friendly technologies currently adopted in China's foundation pit engineering field. It is the first green foundation pit technical standard in China, and its overall level is internationally advanced.

The Rongchuang patented technology included in the "Green Technology Code for Foundation Pit Engineering"

The down-the-hole (DTH) impact high-pressure jet grouting technology (DJP method) included in this standard is a scientific and technological achievement independently developed by Rongchuang Geotechnical and appraised by the Ministry of Housing and Urban-Rural Development as reaching the international advanced level. It is the first in the world to propose the linkage mechanism of "high-pressure water (air), high-pressure grout, and high-frequency vibration," and has made multiple innovations in four major aspects: process, equipment, materials, and management. It can be applied to pile foundations, composite foundations, water-stop curtains, foundation pit support, and other areas, solving related technical challenges under complex strata and complex working conditions, and promoting technological progress in the industry.
