ABSTRACT ：The construction of large volume and variable cross-section concrete in traditional pump station flow channels has disadvantages such as complex processes, long construction periods, severe material loss, and environmental friendliness. An innovative research and development of a combined steel formwork construction technology for sewage treatment pump station horn shaped flow channels has been carried out. The overall steel formwork is made in a complete set, and a sample frame bone support and reinforcement system is added internally. After the overall lifting is in place, steel reinforcement binding and concrete pouring begin. Compared with traditional brick and wood formwork, This construction technology has the advantages of energy conservation, environmental protection, and high efficiency, and has significant engineering application prospects.
