Description

Technical Field

[0001] The utility model belongs to the technical field of ultra-high-rise drainage, and particularly relates to a drainage system for an ultra-high-rise equipment conversion layer. Background Art

[0002] With the continuous increase in the height of ultra-high-rise buildings, the strength requirements for drainage pipes are getting higher and higher. For this reason, the method of setting a horizontal pipe turning in the equipment conversion layer is often used to dissipate energy, so that the gravitational potential energy of sewage will not be too large to cause damage to the pipeline.

[0003] However, since large-length drainage pipes need to be set in high-rise or ultra-high-rise buildings, sewage will turn many times in the horizontal pipe during the drainage process, resulting in the occurrence of water jump phenomenon at the junction of the vertical pipe and the horizontal pipe, making the air pressure fluctuation in the drainage vertical pipe relatively large, which will not only damage the water seal, but also affect the stability of the water flow. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drainage system for an ultra-high-rise equipment conversion layer, aiming to ensure the internal pressure stability of the vertical pipe while avoiding damaging the water seal.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

Under the vertical projection, the drainage vertical pipe is horizontally misaligned;

[0013] Further, a combined vent pipe is provided between the drainage riser and the vent riser. One end of the combined vent pipe communicates with the inner wall of the drainage riser, and the other end of the combined vent pipe communicates with the inner wall of the vent riser.

[0014] Further, under the plumb projection, the two ends of the combined vent pipe are in an inclined posture that is offset from bottom to top and communicate with each other between the drainage riser and the vent riser respectively.

[0015] Further, a combined vent pipe is communicated with the side of the drainage riser on the Nth floor away from the vent riser.

[0025] Combine Figure 1As shown in the figure, a drainage system for the equipment transfer floor of a super high-rise building includes a drainage riser 1, a vent riser 2, a drainage horizontal pipe 3, a vent horizontal pipe 4, and an auxiliary vent pipe 5. The transfer floor is the Nth floor; the drainage riser 1 is vertically arranged between the (N - 1)th floor and the (N + 1)th floor, and the input end and the output end of the drainage riser 1 respectively extend to the (N - 1)th floor and the (N + 1)th floor. Under the plumb projection, the drainage riser 1 is horizontally offset. The vent riser 2 is arranged beside the drainage riser 1, and the input end and the output end of the vent riser 2 respectively extend to the Nth floor and the (N + 1)th floor. The drainage horizontal pipe 3 is arranged between adjacent drainage risers 1 and is connected to the output end and the input end of the adjacent drainage riser 1. The vent horizontal pipe 4 is arranged between adjacent vent risers 2 and is connected to the output end and the input end of the adjacent vent riser 2. The auxiliary vent pipe 5 is respectively connected to the connection points between the drainage riser 1 and the drainage horizontal pipe 3, and between the drainage horizontal pipe 3 and the vent riser 2, and can circulate the air flow between the drainage riser 1 and the drainage horizontal pipe 3, and between the drainage horizontal pipe 3 and the vent riser 2.

[0026] In this application, the transfer floor refers to the floor between the (N + 1)th floor and the (N - 1)th floor in a super high-rise building or a high-rise building, that is, the Nth floor. And the drainage system for the equipment transfer floor of the super high-rise building in this application is applied to the drainage operation scenario of the Nth floor. The drainage system for the equipment transfer floor of the super high-rise building in this application consists of a drainage riser 1, a vent riser 2, a drainage horizontal pipe 3, a vent horizontal pipe 4, and an auxiliary vent pipe 5. The drainage riser 1 is connected to the output end of the sanitary appliances between the Nth floor and the (N + 1)th floor and is used for drainage between each floor of the super high-rise building. The vent riser 2 is arranged beside the drainage riser 1 and is used to relieve the air pressure generated when the water flow on the upper floor passes through the drainage riser 1. The drainage horizontal pipe 3 is connected between the upper drainage riser 1 and the lower drainage riser 1. By relieving the impact generated when the water on the upper floor falls into the drainage riser 1 of the lower floor, the water hammer phenomenon at the connection between the drainage riser 1 and the drainage horizontal pipe 3 is reduced, and the integrity of the structures of the drainage riser 1 and the drainage horizontal pipe 3 is ensured. The vent horizontal pipe 4 is arranged to facilitate the air flow between adjacent vent risers 2 and is used to connect the gas flow between adjacent floors. The water flow generates an upward air flow when passing through the drainage horizontal pipe 3 from the upper floor to the lower floor. The auxiliary vent pipe 5 is respectively connected to the connection points between the drainage riser 1 and the drainage horizontal pipe 3, and between the drainage horizontal pipe 3 and the vent riser 2, to avoid the pressure imbalance of the air inside the drainage riser 1 caused by the disorder of the air flow in the drainage horizontal pipe 3, so as to avoid the instability of the water seal at the output end of the sanitary appliances connected to the upper floor.

[0027] A combined vent pipe 6 is arranged between the drainage riser 1 and the vent riser 2. One end of the combined vent pipe 6 is connected to the inner wall of the drainage riser 1, and the other end of the combined vent pipe 6 is connected to the inner wall of the vent riser 2.

[0028] In the above solution, the combined vent pipe 6 is connected between the exhaust riser and the vent riser 2. When water flows downward through the exhaust riser, an upward air current is generated, and the upward air current will cause the wastewater flowing downward to float upward. The setting of the combined vent pipe 6 can disperse the upward air current generated when the drain riser 1 drains downward into the lumen of the vent riser 2, so that the air current in the exhaust riser escapes into the vent riser 2 to balance the air current in the vent cross pipe 4 and the exhaust cross pipe in the lower layer, thereby avoiding the wastewater flowing downward from floating upward and causing the wastewater and waste gas to flow back into the sanitary appliances on the same floor.

[0029] Under the plumb projection, the two ends of the combined vent pipe 6 are connected between the drain riser 1 and the vent riser 2 in a tilted posture that is offset from bottom to top.

[0030] In the above solution, the low end of the combined vent pipe 6 is connected to the side wall of the drain riser 1, and the high end of the combined vent pipe 6 is connected to the side wall of the vent riser 2. Such a setting can prevent the wastewater flowing downward from splashing into the vent riser 2 during the falling process, not only avoiding the pollution of the interior of the vent riser 2 by the wastewater, but also ensuring that the vent riser 2 can exhaust normally.

[0031] A drain branch pipe 7 is connected to the side of the drain riser 1 on the Nth floor away from the vent riser 2. The drain branch pipe 7 includes a vertical section 71 and a horizontal section 72. One end of the vertical section 71 extends to the (N + 1)th floor and is connected to the output end of the external appliance on the (N + 1)th floor. The other end of the vertical section 71 is connected to one end of the horizontal section 72, and the other end of the horizontal section 72 is connected to the drain riser 1.

[0032] In the above solution, the purpose of setting the drain branch pipe 7 is to be able to drain the wastewater of the sanitary appliances on the same floor into the drain riser 1 on the next floor through the drain riser 1. The drain branch pipe 7 includes a vertical section 71 and a horizontal section 72. The vertical section 71 is connected to the output end of the sanitary appliance on the upper floor, providing a drainage space for the sanitary appliance on the upper floor. The horizontal section 72 is connected to the exhaust riser to facilitate the wastewater to flow down to the next floor.

[0033] The connection between the vertical section 71 and the horizontal section 72 has a bent structure 73. The upstream liquid level of the bent structure 73 is flush with the downstream liquid level of the bent structure 73, which can form a space for storing wastewater.

[0034] In the above solution, the setting of the bent structure 73 provides a storage space for the wastewater, forming a water seal bend. Such a setting separates the cavity between the vertical section 71 and the horizontal section 72, avoiding the backflow of wastewater and waste gas due to the upward air current when the wastewater flows into the drain riser 1, so as to ensure a good experience for the user.

[0035] The diameter of the drainage branch pipe 7 is smaller than that of the drainage horizontal pipe 3, the drainage vertical pipe 1, the vent vertical pipe 2, and the vent horizontal pipe 4. The purpose of this setting is to avoid damaging the structural stability among the drainage horizontal pipe 3, the drainage vertical pipe 1, the vent vertical pipe 2, and the vent horizontal pipe 4 due to water flow and air flow.

[0036] The various embodiments in this specification are described in a progressive manner. For the same or similar parts among the various embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.

[0037] The above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting the present application; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the present application.
