Technology Research on Optimization of Cable Laying in Subway Substation Based on BIM Technology
Most of the subway substations are hidden underground,cable construction in substation has the characteristics of limited space,large number of cables and complex interface.Cable construction has low fault tolerance rate and high reword cost,thus needs special optimization,so as to achieve the purpose of one-time success and cost saving.Relying on the construction of Suzhou Rail Transit Line 11,this paper researches the technology of cable automatic addressing technology,analyzes the process of precise layout of facilities,conflict avoidance and route planning of cables.Based on the research above,we make clear the layout principle of cable in each layer,put forward a simulated cable laying scheme based on automatic addressing and BIM technology,and realize automatic control of cable crossing,bending radius,occupancy rate,cable reservation,etc.,which can remarkably improve the efficiency of construction management and control of subway substations.
