The Design Innovation of the First"Overhead+Superstructure Development"Overhaul and Heavy Repair Metro Depot in China
Research purposes:The spatial form of the comprehensive development of the overhaul and heavy repair metro depot of"overhead+superstructure development"has no precedent in China,and it is necessary to solve the technical problems such as the fragmentation of urban land and space by the construction of vehicle base,the utilization of ground floor space,the improvement of the development intensity of covered property,vibration and noise reduction,and the laying of equipment foundation and pipeline.Through the design practice of the first"overhead+superstructure development"overhaul and heavy repair metro depot in China,this paper puts forward an engineering scheme to solve the above technical problems for reference by peers in the industry.Research conclusions:(1)The overhead scheme can effectively reduce the fragmentation of urban land and space by the construction of vehicle bases;(2)By covering the core structure of the property,the garage of the superstructure can be replaced to the ground floor,which can efficiently use the ground floor space and improve the intensity and income of property development;(3)In the throat area,the inspection pit in the warehouse and the large-scale use of rubber spring floating plate vibration damping track bed and other measures can better solve the vibration and noise problem of the metro depot;(4)The use of overhead plate sinking and local space of the ground layer can solve the problem of equipment foundation and pipeline laying;(5)The ideas and methods proposed in this research result have reference and reference value for similar engineering construction.
