Directly reporting from the 51st World Tunnel Congress (WTC 2025)
We are honored to be invited to participate in the 51st World Tunneling Congress (WTC 2025) held in Stockholm and give a keynote speech.
The World Tunnel Congress is organized by the International Association of Tunnels and Underground Spaces (ITA) and is held annually. It is currently the most influential and authoritative conference in the tunnel and underground engineering industry worldwide. During the conference, representatives of ITA member states will exchange topics and showcase technology and equipment.
Our team has been rooted in the tunnel industry since 1999 and established Biaosheng Technology Experimental Co., Ltd. with independent research and development capabilities in 2020. We have been committed to innovation and aim to become a leading enterprise in the tunnel industry. The company has established offices and laboratories in Shanghai, Singapore, and Canada.
Since its establishment 5 years ago, we have introduced multiple research and development achievements to elite tunnel enterprises and individuals worldwide, and have received widespread praise.
Jelly paste
Jelly slurry is a new type of material used in shield tunneling and pipe jacking engineering, which has multiple functions such as reducing friction, preventing settlement, stabilizing the formation, and blocking water. Its performance is significantly better than ordinary bentonite slurry.
Debut: In 2019, jelly slurry was first applied to the top pipe project of Jing'an Temple in Shanghai, helping the project win the "Excellent Engineering Award" of the International Tunnel Association.
Continuous optimization: After thousands of experiments and on-site debugging, we have developed a complete set of supporting equipment and established the industry's first jelly slurry company standard.
International Promotion:In 2024, the first themed presentation will be given to North American industry elites at the No Dig North conference; In the same year, jelly slurry passed the strict acceptance of LTA with excellent performance in the N109A and T316 projects in Singapore, becoming the first international successful case. At the end of the year, I was invited to give a speech at the British Tunneling Association conference, introducing Chinese innovative technologies to the European market.
Industry recognition:In 2025, "Tuning Journal" conducted an exclusive interview with Biaosheng Technology to provide in-depth coverage on the application of jelly slurry; At present, jelly slurry has been implemented in over 15 projects in Asia, and several leading construction units in Europe and America have expressed their intention to cooperate.
Shield tail sealing grease
Faced with the problem of a lack of unified evaluation standards in the industry, we have been dedicated to research since the establishment of our company, accumulating a large amount of on-site and laboratory data. We have worked closely with the owner and construction team to establish multiple evaluation criteria for shield tail grease. Based on 25 years of industry accumulation and on-site debugging experience, we have created our own brand product line (Shield Tail Pumping Oil TS G60, Shield Tail Hand Coating Oil TS GFF, Main Drive Sealing Oil TS MBG, etc.) and mass produced them on advanced production lines in Europe.
Other innovative projects
Resource utilization of shield tunneling waste soil
We have signed a strategic cooperation agreement with a listed company in Europe to jointly develop technology for the reuse of waste soil generated during shield tunneling construction. The project, with the core goal of "resource utilization of shield tunneling waste", is steadily advancing at multiple testing sites in Europe and Asia, committed to providing more environmentally friendly and efficient waste disposal solutions for the tunnel industry.
Shield tunneling waste slurry treatment technology
We are conducting research on efficient solid-liquid separation and volume reduction treatment processes for the large amount of waste slurry generated during shield tunneling construction, aiming to reduce transportation and processing costs and achieve green closed-loop management of waste slurry.
New Shield Tail Sealing System
Based on the shortcomings of traditional sealing systems in terms of durability and environmental friendliness, we propose the concept of "synchronous sealing" and are currently conducting system level conceptual design and key material screening. This system is expected to improve the sealing performance during shield tunneling, providing a new solution for the operation of long-life and zero leakage tunnels in the future.
We believe that continuous technological exploration and open cooperation will lead Biaosheng Technology to go more steadily and further in the international tunnel industry.
