摘要:
上海中心城区Φ3 500 mm合流总管为钢筋混凝土管，已运行30多年。由于污水的腐蚀作用，管道内侧发生了严重的钢筋裸露和锈蚀，承载力下降。该总管位于高架下方，周边环境复杂。为确保合流总管结构和周边环境的安全，通过地面临排+中导管的组合临排形式创造干仓环境，采用8 mm不锈钢内衬对管道进行修复，不锈钢内衬与原管道之间的空隙注入灌浆材料。修复后合流总管运行正常，不锈钢内衬、灌浆材料和原结构形成复合结构，恢复了原设计承载能力。
Abstract:
The combined sewer pipe, with a diameter of Φ3 500 mm, located in the central urban area of Shanghai, has been in service for over 30 years and is constructed from reinforced concrete. The corrosive nature of sewage has resulted in significant exposure and rusting of the rebar on the interior of the pipe, consequently diminishing its load-bearing capacity. This main pipe is situated beneath an elevated structure, and the surrounding environment is characterized by complexity. To ensure the structural integrity of the combined sewer main pipe and the safety of the surrounding area, a dry repair environment was established through a combined temporary drainage of surface pipes and inner conduits. An 8 mm stainless steel liner was employed for the repair of the pipeline, with the space between the stainless steel liner and the original pipe filled with grouting material. This assembly of the stainless steel liner, grouting material, and the original structure resulted in a composite structure that effectively restored the original design load?bearing capacity. Following the repair, the combined sewer has resumed normal operations.
