Reconstruction and Strengthening of Yangshupu WaterworksAs the first factory in Shanghai, the Shanghai Fifth Woolen Factory witnessed the development of Shanghai's industry. In Yangshupu water plant renovation and expansion project in Shanghai, in strict accordance with the historical style of building protection requirements, combined with historical protection of the status of the building and the transformation of the actual functional requirements, the system to solve the protection and transformation of the use of technical problems.

  Engineering Background:

  As the first factory in Shanghai, the Shanghai Fifth Woolen Factory witnessed the development of Shanghai's industry. In Yangshupu water plant renovation and expansion project in Shanghai, in strict accordance with the historical style of building protection requirements, combined with historical protection of the status of the building and the transformation of the actual functional requirements, the system to solve the protection and transformation of the use of technical problems. On the do not meet the requirements of the existing norms of plant structure for large-scale structural system transformation.

  solution:

  By using all kinds of strengthening methods synthetically, the advantages of various methods are exerted to the utmost, and the components with relatively low strength grade are strengthened effectively. In the original large-scale factory structures within the pipe jacking operation, the top tube to be through the original foundation at the bottom. Based on the results of on - site monitoring, the whole process of the structure reaction in the pipe jacking process is calculated and analyzed, and the analysis results are verified by the monitoring results of a limited number of internal force monitoring points. Which provides a scientific basis for decision-making, ensures the safety of structures under complicated construction conditions, and avoids adverse effects on adjacent buildings. The reinforcement of the internal structure of the foundation pit excavation, pipe jacking construction deformation and bearing capacity of the review check.
