Description

Technical Field

[0001] This utility model belongs to the field of building drainage technology, and in particular relates to a drainage structure for a high-rise public building that includes a hotel functional area. Background Technology

[0002] In high-rise public buildings containing hotel functional areas, the hotel's domestic water supply system on floors 1-3 is quite complex, with water usage occurring at various times. The kitchen has the highest water consumption, and the hotel's water usage periods are relatively concentrated, with a high probability of peak water usage occurring simultaneously. The hotel's domestic water supply system on floors -1-3 is also complex, with water usage occurring at various times. The kitchen has the highest water consumption, with a calculated design flow rate of 15 L / s. The bathrooms, based on hotel functions, have a design flow rate of 4.28 L / s and an average hourly flow rate of 3.78 L / s. If the design water consumption for this area is calculated by adding the kitchen's water consumption and the bathroom's average hourly flow rate, the difference in water consumption is not significant. Furthermore, given the concentrated water usage periods and the high probability of peak water usage occurring simultaneously, how to design the drainage system for this area is a problem that needs to be solved. Summary of the Invention

[0003] The purpose of this utility model is to solve the technical problems in the prior art and provide a drainage structure for high-rise public buildings that include hotel functional areas.

[0004] To achieve the above objectives, a drainage structure for a high-rise public building including a hotel functional area is designed. The hotel functional area includes a functional area and a guest room area. The guest room area has multiple floors with guest rooms. Each guest room's bathroom is equipped with a drainage pipe. A transfer floor is installed on the lowest floor of the hotel guest room area. The drainage pipes of all guest rooms converge on this floor, forming at least three converging areas. Each converging area is connected to a sewage pipe.

[0005] The drainage pipes of the bathrooms in the guest rooms on the equipment conversion floor are connected to the horizontal drainage pipe. Each bathroom in the guest rooms on this floor has a ring-shaped vent pipe between the two sanitary fixtures at its drainage point, which is connected to its respective vent pipe.

[0006] The three confluence areas are equipped with a common ventilation pipe.

[0007] Preferably, the shared ventilation pipe extends to the roof surface of the high-rise public building for ventilation.

[0008] Preferably, the guest room area, except for the separate drainage pipes and wastewater pipes of the equipment conversion floor, shares a common vent pipe.

[0009] Preferably, in the equipment conversion layer, all the sewage and wastewater risers from the guest room bathrooms converge on this layer before entering the water pipe well and then going down to the first floor to be discharged outdoors.

[0010] Preferably, the functional areas include hotel public restrooms, staff restrooms, and office restrooms, with sewage and wastewater pipes combined and discharged outdoors.

[0011] Preferably, in the functional area, the drainage from the underground toilets is discharged to the underground sewage room via an integrated sewage lifting device and then to the outside, while the drainage from each kitchen is discharged to the grease trap room on the second basement floor, where it is separated by a high-efficiency grease separator before being discharged to the outside.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. The water usage of the kitchen and bathroom is reasonably combined to ensure that the hotel's drainage needs can be met during peak water usage periods.

[0014] 2. By installing a ring-shaped vent pipe between the two sanitary fixtures at each bathroom drain point in the guest rooms, and a shared vent pipe in the confluence area, the drainage effect of the horizontal drain pipe is effectively guaranteed, blockage problems are avoided, and the smooth operation of the entire drainage system is facilitated.

[0024] To make the purpose, principle and structure of this utility model clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1-6 The drainage structure for the high-rise public building provided in this embodiment includes a hotel functional area, which is divided into two parts: the functional area and the guest room area. The functional area includes public restrooms, staff restrooms, and office restrooms, with sewage and wastewater pipes combined and discharged outdoors. The guest room area spans floors 16-20, with each guest room's bathroom equipped with a drainage pipe. The building also includes a swimming pool, fitness center, etc., with each guest room's bathroom equipped with a drainage pipe. Floor 11 is an equipment transfer floor. All guest room bathroom sewage and wastewater risers converge on this floor before entering a water pipe shaft and then descending to the first floor for discharge outdoors. Sewage and wastewater from guest rooms on floors 12-20 are separated but share a vent pipe. Roof vent pipes that can extend directly to the roof for ventilation are used; otherwise, a combined ventilation system is used for roof ventilation.

[0026] The hotel's public restrooms, staff restrooms, and office restrooms use a combined sewage and wastewater drainage system that discharges wastewater outdoors. Drainage from the restrooms on the first basement level is discharged to the second basement level via an integrated wastewater lifting system. Drainage from each kitchen is discharged to the second basement level grease trap room, where it undergoes grease separation using a high-efficiency grease separator before being discharged outdoors.

[0027] See Figure 7 , Figure 8 The drainage of the bathrooms in the 12th floor of the hotel is connected to the horizontal drainage pipe. A ring-shaped vent pipe 1 is installed between the two sanitary fixtures at the drainage starting point 2 of each bathroom on the 12th floor, which is connected to their respective vent pipes to ensure the drainage effect of the horizontal drainage pipe. A common vent pipe is installed in the middle of the three sewage and wastewater main pipes. The distance from the 11th floor to the 1st floor is relatively large. After the three vent pipes converge on the 11th floor, they extend to the roof through a common pipe shaft for ventilation.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and novel concept of this utility model, should be included within the protection scope of this utility model.
