The Haihe River Tide Barrier Risk Elimination and Reinforcement Project is one of the 150 major national water conservancy projects. In order to effectively build the project into a high-quality project of water conservancy construction in the Haihe River Basin, since the commencement of the project, the Construction Management Bureau of the Haihe River Tide Barrier Risk Elimination and Reinforcement Project has earnestly implemented the work arrangements of the Haihe River Water Conservancy Commission and the Haihe River Lower Reaches Administration, adhered to goal orientation, systematic planning, and cooperative integration, actively explored the application and implementation of new technologies and new applications in project construction, promoted the deep integration of scientific and technological innovation and construction technology, and continuously deepened the transformation and application of achievements. While completing the project construction with high quality on schedule, it has formed a series of scientific and technological achievements, providing solid technical support and valuable experience for the construction and management of water conservancy projects in the lower reaches of the Haihe River.

In terms of project management, it has actively explored the application of new technologies, used new-generation information technologies such as the Internet, big data, artificial intelligence, and BIM, and organized the development of a digital, visual, intelligent, and professional smart construction site for the Haihe River Tide Barrier Risk Elimination and Reinforcement Project that integrates multi-functional comprehensive business management such as safety, quality, progress, risk, and Party building work.

In terms of digital twins, it has strictly followed the various requirements for the synchronous delivery of digital twin projects for water conservancy projects, carried out digital mapping, intelligent simulation, and forward-looking preview of all elements of the project and the entire operation process, and conducted synchronous simulation operation, virtual-real interaction, and iterative optimization with the project. It has implemented the construction of a digital twin Haihe River barrier based on the physical Haihe River Tide Barrier Project, realizing real-time monitoring, early warning monitoring, and optimized scheduling of the project.

In terms of technological innovation, it has dared to break through tradition and actively explored the application of new technologies in the project. In the construction of temporary works, it took the lead in Tianjin in successfully using steel sheet pile cofferdams for water retention, reducing the project land occupation and earthwork volume. The project "Research on Key Construction Technologies of Steel Sheet Pile Cofferdams in Tidal River Reaches," which it led to completion, won the third prize for scientific and technological progress in water conservancy of the Haihe River Water Conservancy Commission. At the same time, it innovatively adopted SMW method piles (a new type of cement-soil mixing pile wall) for the support structure of diversion structures, improving the stability and safety of the project and providing new ideas and methodological references for the construction of related water conservancy projects under the bureau. The completed project "Key Technologies for Safety Networking Monitoring of Water Conservancy Projects and Remote Sensing Intelligent Identification of Flood Disasters" won the second prize of the China Beidou Association.

In terms of achievement transformation, research results such as "A Safety Protection Device for Water Conservancy Project Construction" and "A Guiding Device for SMW Method Pile Construction" obtained national utility model invention patents. The Shui Zhi Lan QC (quality control) group and the Shui Zhi Yu QC group continuously studied and actively explored in quality management. Their completed achievements such as "Improving the One-Time Acceptance Pass Rate of the Thickness of the Rebar Protective Layer of Special-Shaped Structures" and "Reducing the Concrete Cracking Rate of the Haihe River Tide Barrier Pier During Winter Construction" were rated as excellent quality management groups of water conservancy enterprises (projects) by the China Water Enterprises Confederation. During the project construction period, technical personnel from all participating parties wrote more than 20 scientific and technological papers of various types, among which papers such as "A Brief Analysis of Cultural Relics Protection in the Haihe River Tide Barrier Risk Elimination and Reinforcement Project," "Discussion on the Pile Driving Construction Scheme of Steel Sheet Pile Cofferdams in Coastal Areas," and "Analysis of Safety Risks in Water Conservancy Projects and Application of Information Technology" won awards respectively at the academic annual meeting of the Tianjin Water Conservancy Society and in the paper evaluations of the Haihe River Water Conservancy Commission and the Haihe River Lower Reaches Administration.

In terms of academic exchange, one English extended abstract, "Thoughts on Enhancing Flood Control and Tide Protection Safety Guarantee Capacity in the Coastal Areas of the Lower Reaches of the Haihe River Basin under the Normalization of COVID-19 Epidemic Prevention and Control" ("New Coronavirus pneumonia epidemic prevention&control normalization to enhance the coastal area of Haihe River Basin flood control&flood protection capability"), received an invitation to attend and speak at the "9th International Conference on Flood Management (ICFM9)" hosted by the International Centre for Water Hazard and Risk Management under the auspices of UNESCO in Tsukuba, Japan, and was included in the conference proceedings.

Next, the Construction Management Bureau of the Haihe River Tide Barrier Risk Elimination and Reinforcement Project will further consolidate and expand its technical advantages in the field of water conservancy project construction, strengthen the application of water conservancy engineering technology and the summarization of construction management experience, continue to deepen the transformation and application of technological achievements, and make greater contributions to the high-quality development of water conservancy undertakings in the lower reaches of the Haihe River.
