[0002] In order to meet the needs of people in residential areas for travel and living environment, basements are set up during planning and design to separate people and vehicles for easy management. However, in areas with abundant and concentrated rainfall, urban waterlogging and rainwater backflow in basements often occur.

[0003] Conventional basement drainage systems discharge directly into outdoor municipal pipes. In the face of huge amounts of rainwater, urban waterlogging and human factors often make it impossible for basement floods to be discharged, and there is even a risk of flooding back into the municipal pipe network.

[0004] Therefore, the applicant, with many years of rich experience in design, development and actual production in the relevant industry, has studied and improved the existing structure and defects, and provided a basement fire protection pipeline and flood drainage device and its construction method, expanding the water collection well beside the basement fire water pool to use it as a flood control water collection well, adding drainage ditches between the water collection wells in the basement to connect them in series, installing a high-power water pump, and connecting its drainage pipe with the fire drainage pipe to achieve the effect of rapid flood drainage. It is convenient during construction, quick to drain floods, and highly operable, in order to achieve a more practical purpose. Summary of the invention
