The function of the submersible sewage pump is based on the total flow rate and head, and the pump is selected in the efficient area of the submersible sewage pump characteristic curve. And pay attention to choosing a submersible pump with a small protection height. Most submersible sewage pump units have one for one purpose and one for standby. When there are multi-story underground garages or large drainage volumes, multiple pumps should be connected in parallel (multiple pumps have one standby). In addition, when there are toilets and other living facilities in the underground garage, the domestic sewage should be discharged through independent pipes, an independent sewage collection well, and an independent submersible sewage pump should be installed to prevent domestic sewage and odor from escaping through floor drains, and ventilation pipes should be installed for high-altitude discharge. For odor, it is advisable to use a submersible sewage pump that can cut or allow the passage of particles of corresponding particle size. A brief discussion on the water supply and drainage design scheme of underground garages in modern residential areas. Abstract: With the development of the economy, the scale of underground (or semi-underground) parking garages in residential areas has increased, the functions have been enhanced, and the grade has been improved. The content of water supply and drainage design has also become more and more important. . This article combines the author's work experience with practical problems encountered in design and proposes solutions. Keywords Underground garage fire water supply and drainage design plan description In some developed areas, with the vigorous development of the national economy and the continuous improvement of people's living standards, the number of family cars has increased rapidly, and the parking space configuration standards in some residential areas have become insufficient. In addition, people's requirements for the living environment are getting higher and higher, and small bridges, flowing water, birds singing and the fragrance of flowers have gradually become the basic elements of community garden construction. All these make the construction of large and extra-large underground (or semi-underground) parking garages an inevitable trend in future community construction. Based on the water supply and drainage design example of an underground garage in a large local residential area, the author elaborates on the design points of the underground garage water supply and drainage and the practical problems encountered in the design one by one. The architectural characteristics of underground garages in modern residential areas are: first, large scale and large construction area of the garage.
