With a total of two patents to his name, Chen's work focuses on enhancing the structural integrity and sustainability of construction materials.

Latest Patents

Rong Chen's latest patents include a shield tunnel segment structure and a construction method thereof. This invention involves a unique design of segment blocks that are sequentially spliced in a circumferential direction. Each segment block forms a closed annular segment structure, with outer diameters of adjacent annular segment structures gradually increasing in an axial direction. The design features annular inner and outer grooves that enhance the structural stability of the tunnel segments.

Another significant patent by Chen is related to high-strength concrete and its preparation method. This innovative concrete formulation includes lignin, recycled fine powder, cement, water, sand, gravels, and a water-reducing agent. The use of recycled fine powder from discarded concrete not only promotes sustainability but also improves the overall strength of the concrete. The preparation process involves several steps, including the extraction of lignin from discarded wood, which contributes to the eco-friendliness of the material.
