Description

Technical Field

[0001] The present application relates to the technical field of building water supply and drainage, and in particular to a super high-rise drainage and ventilation system. Background Art

[0002] Currently, Article 4.5.7 of the "Building Water Supply and Drainage Design Standard" GB50015-2019 stipulates that the drainage capacity of high-rise buildings with more than 15 floors needs to be multiplied by a coefficient of 0.9, and this coefficient will be smaller for super high-rise buildings. Super high-rise buildings refer to buildings with a height of more than 100 meters.

[0003] The wind speed at the same location increases with the height from the ground. The wind speed in super high-rise buildings is 1.5 to 2.5 times that of ordinary high-rise buildings. More and more super high-rise buildings cannot be ventilated on the top due to their shape, and can only be ventilated on the side walls. However, there is only one existing side wall vent pipe. When encountering special weather, natural wind can easily flow back into the drainage riser, thereby destroying the water seal. Utility Model Content

[0004] The embodiment of the present application provides an ultra-high-rise drainage and ventilation system, which solves the technical problem in the prior art that only one side wall ventilation pipe is provided, and when encountering special weather, natural wind is easy to flow back into the drainage riser, thereby causing the water seal to be destroyed.

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0018] The present application embodiment provides a super high-rise drainage and ventilation system, such as Figure 1 As shown. The super high-rise drainage and ventilation system includes a drainage riser 1, a connecting pipe 2 and four side wall ventilation pipes 3. The top of the drainage riser 1 extends out of the building side wall. The connecting pipe 2 is connected to the top of the drainage riser 1, and four flow grooves are arranged along its circumference. The four side wall ventilation pipes 3 are connected to the four corresponding flow grooves, and the axial directions of the four side wall ventilation pipes 3 all avoid the local dominant wind direction. The axial directions of the four side wall ventilation pipes 3 are perpendicular to the axial direction of the drainage riser 1.

[0019] Furthermore, the connecting pipe 2 can be detachably connected to the top of the drainage riser 1, so that it can be adapted to super high-rise buildings in different regions.

[0020] In the prior art, super high-rise buildings cannot be ventilated on the roof due to shape restrictions, and side wall ventilation will cause natural wind to flow back into the drainage riser 1, thereby destroying the water seal.

[0021] It should be noted that the embodiment of the present application is provided with four side wall vent pipes 3. When wind blows in from any side wall vent pipe 3, it blows out from the two adjacent side wall vent pipes 3, thereby balancing the natural wind pressure. Therefore, the super high-rise drainage ventilation system of the present application changes the ventilation mode, reduces the influence of natural wind backfill on the air pressure in the drainage riser 1, and improves the safety of the water seal and the stability of the drainage system.

[0022] In the prior art, the drainage riser 1 is connected to the ventilation riser. The super high-rise drainage and ventilation system reduces the impact on the air pressure in the drainage riser 1 and also reduces the impact on the ventilation riser.

[0023] In the embodiment of the present application, the super high-rise drainage ventilation system further comprises four side wall ventilation caps 4. The four side wall ventilation caps 4 are respectively arranged at one end of the side wall ventilation pipe 3 away from the connecting pipe 2.

[0024] It should be noted that the side wall vent cap 4 can prevent large debris from entering the side wall vent pipe 3 .

[0025] In the embodiment of the present application, the diameter of the drainage riser 1 is DN200 or DN250 or DN300.

[0026] The maximum pipe diameter of the drainage riser 1 in the prior art is DN150. However, there are many super-high-rise floors. If one drainage riser 1 serves too few floors, the total number of drainage risers 1 in the entire building will be too large, and the floor area of ​​the risers will be large, which will virtually reduce the actual use area of ​​the building, and will not save land, materials, or energy.

[0027] The present application increases the diameter of the drainage riser 1 , and in actual use, also increases the diameter of the ventilation riser, further reducing the adverse effects of pressure fluctuations.

[0028] In the embodiment of the present application, the connecting pipe 2 includes a first semicircular flow groove 21, a second semicircular flow groove 22, a third semicircular flow groove 23 and a fourth semicircular flow groove 24. The first semicircular flow groove 21, the second semicircular flow groove 22, the third semicircular flow groove 23 and the fourth semicircular flow groove 24 are connected in sequence to form a closed structure.

[0029] It should be noted that the first semicircular flow groove 21, the second semicircular flow groove 22, the third semicircular flow groove 23 and the fourth semicircular flow groove 24 allow the wind entering from any side wall ventilation pipe 3 to be blown out smoothly from the two adjacent side wall ventilation pipes 3.

[0030] In the embodiment of the present application, the drainage riser 1 extends into the connecting pipe 2 .

[0031] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0032] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
