From July 16 to 18, the 34th Annual Academic Conference of the Tunnel Engineering Branch of China Highway and Transportation Society was grandly convened in Wenzhou, Zhejiang Province. Centered on the theme “Tunnels across Oujiang · Smart Safe Passage — Smart, Green, Resilient and Innovative”, the conference gathered more than 200 engineering enterprises and institutions nationwide and nearly 600 industry experts. The conference released the *2026 Key Promotion Catalogue of “Four‑New Technologies” for Highway Tunnels*, which includes a total of 48 nationally‑recognized innovative technologies. The special flood‑resistance facilities and system for tunnels independently developed by Nanjing Junli Technology Co., Ltd. have been successfully selected into the catalogue. 
Against the backdrop of prominent flood‑prone risks for domestic urban tunnels, Junli’s special flood‑resistance facilities and system for tunnels closely follow the core construction principle of “prioritizing water‑blocking combined with drainage” specified in the *Jiangsu Provincial Guidelines for Urban Tunnel Flood‑Resistance Work (Trial)*. After comprehensive reviews by multiple rounds of expert panels, the product system was successfully shortlisted for the annual key promotion catalogue.
This inclusion represents authoritative recognition from China Highway and Transportation Society of the technical advancement and practical engineering value of Junli’s flood‑resistance technologies. Going forward, leveraging the promotion opportunities brought by the catalogue, Junli Co., Ltd. will continuously optimize flood‑resistant products and further improve its technical capabilities for tunnel flood prevention.
