Title: Innovations of Zhanglun Song in Aquifer Grouting Methods

Introduction

Zhanglun Song is a notable inventor based in Beijing, China. He has made significant contributions to the field of aquifer engineering, particularly through his innovative grouting methods. His work focuses on enhancing the stability and integrity of ramps in aquifers, which is crucial for various construction and environmental applications.

Latest Patents

Zhanglun Song holds a patent for a segmented grouting method for ramp drivage in an aquifer. This method involves a systematic approach divided into four stages based on pressure changes: micro-pressure filling, low-pressure diffusion, medium-pressure reinforcement, and high-pressure fracturing. In the micro-pressure filling stage, a low-concentration single-component grout is used to fill the original fissures of the aquifer. The low-pressure diffusion stage employs a low-concentration bicomponent grout to expand these fissures and increase the grouting radius. The medium-pressure reinforcement stage utilizes a high-concentration bicomponent grout to strengthen the aquifer. Finally, the high-pressure fracturing stage reinforces new fractured fissures caused by high pressure, forming a confining bed.

Career Highlights

Zhanglun Song has worked with Norin Mining Limited and the University of Science and Technology Beijing. His experience in these institutions has allowed him to apply his innovative ideas in practical settings, contributing to advancements in aquifer management and engineering.

Collaborations

Zhanglun has collaborated with notable colleagues such as Chao Liu and Yunpu Qi. Their joint efforts have furthered research and development in the field of aquifer engineering.

Conclusion

Zhanglun Song's innovative segmented grouting method represents a significant advancement in aquifer engineering. His contributions are vital for improving the safety and efficiency of construction projects involving aquifers.
