Abstract

Aiming at the problem of high runoff coefficient caused by unreasonable pipeline layout in the whole drainage system of sponge airport, a whole drainage system of sponge airport is designed based on BIM. In the hardware, the data acquisition and power supply module is designed by using the main control chip, a variety of sensors and their front-end circuits to complete the voltage conversion. In the software, according to the whole structure of the sponge airport drainage system, this paper determines the rainwater treatment facilities and their combination, and calculates the scale of the drainage facilities. In this paper, the location of BIM is selected, the road layout and pipeline distribution are integrated, and the whole drainage model is established. The design rain pattern of the system test adopts Chicago rain pattern, the rainfall duration is 2h, the rainfall peak rainfall coefficient is 0.4, and the return period is 10 years. The results show that the average runoff coefficient of the system designed in this paper is 0.403, which is 0.374 and 0.376 lower than the whole airport drainage system based on LID and SWMM. Therefore, the system can significantly reduce the airport runoff and has high practical value.
