Municipal rain and sewage pipe network information storage method based on BIM

The invention provides a BIM (Building Information Modeling)-based municipal rain and sewage pipe network information storage method, which comprises the following steps of: firstly, mounting a sensor at a proper part of a municipal rain and sewage pipe network, and collecting data information of related parts through the sensor; generating a three-dimensional model of the rain sewage pipe network through a BIM technology according to the collected information; obtaining an accurate three-dimensional model of the rain sewage pipe network through a block chain consensus algorithm, and storing the three-dimensional model to a public chain; data information of related parts of the rainwater and sewage pipe network is continuously collected through a sensor, the three-dimensional model on each computer is updated in real time, and all-time monitoring of the rainwater and sewage pipe network is completed; according to the method, the problem that information stored in a computer is not safe ...
