Description

Technical Field

[0001] The present invention relates to the field of fixed buildings, and in particular to a comprehensive system suitable for a fully underground water plant. Background Art

[0002] With the continuous development of my country's economy, people's requirements for the environment are getting higher and higher. In order to improve the current situation of water pollution, my country has invested in the construction of a large number of sewage treatment plants in recent years. Their process composition and construction scale vary, but in terms of construction mode, the vast majority of reclaimed water plants or sewage treatment plants are above-ground. Above-ground sewage treatment plants have the advantages of good ventilation and sufficient light, but the construction of above-ground sewage treatment plants, on the one hand, there are problems of waste of land resources and environmental pollution, and on the other hand, it will cause the depreciation of surrounding land resources. With the improvement of my country's urbanization level and residents' environmental requirements, underground reclaimed water plants or sewage treatment plants that can coordinate with the external surrounding environment, have strong closure and no secondary pollution have become a new development trend and direction for the construction of urban sewage treatment projects.

[0003] Although fully underground recycled water plants or sewage treatment plants have many advantages, they also have many disadvantages, mainly including the following:

[0004] 1. The factory has defects such as insufficient lighting and poor ventilation.

[0005] 2. The integration degree between underground sewage treatment area and ground landscape park is low. At present, the underground area of ​​my country's fully underground recycled water or sewage treatment plants is sewage treatment facilities, and the above-ground area is mostly ecological landscape park. There are many auxiliary buildings protruding from the ground in fully underground recycled water plants or sewage treatment plants, such as stairwells, wind shafts and other facilities. In order to improve the lighting of fully underground sewage treatment plants, the usual practice is to increase the electric lighting in the underground area, or set up a single lighting patio in a local area. The lighting patios are scattered and numerous, which is difficult to coordinate with the surrounding landscape environment on the ground, and has a great impact on the overall layout of the ground park.

[0006] 3. There are a large number of stairwells on the ground, which has caused great damage to the overall layout of the ground landscape. A large number of air shafts protruding from the ground have also become a restrictive factor affecting the beauty of the ground landscape, reducing space utilization and increasing costs. Regarding the setting principles of fire exits in fire compartments of fully underground sewage treatment plants, the design concepts of architects are mostly based on the requirements of Article 3.7.2 of the Code for Fire Protection Design of Buildings GB50016. The number of safety exits for each fire compartment in the plant or each floor within a fire compartment should be determined by calculation and should not be less than 2. According to this specification, fully underground sewage treatment plants in many areas now have two stairwells as safe entrances and exits for each fire compartment. According to the process layout requirements, the unit treatment scale of fully underground sewage treatment plants or reclaimed water plants occupies a building area of ​​approximately 2,400 m 2 / 10,000 tons of water, and according to the specification, the area of ​​each fire compartment shall not exceed 2000m 2 Therefore, the underground building area of ​​a large-scale fully underground sewage treatment plant will be divided into multiple fire zones, some with up to 20 fire zones. Each fire zone will have more than 2 stairwells leading to the ground, and there will be nearly 40 stairwell safety exits on the ground. At the same time, fully underground industrial buildings / reclaimed water plants should be equipped with natural air supply or mechanical air supply and exhaust systems. According to traditional engineering design ideas, a large number of mechanical air supply shafts are arranged in the core area of ​​the central part of the water plant to provide mechanical air supply for the plant area.

[0007] 4. The unreasonable building layout increases the cost of the underground sewage treatment plant. Each fire compartment has more than two stairwells leading to the ground, and a large number of mechanical fan shafts are added, which are disguised as adding partitions to the underground production area, blocking the underground space and making it fragmented, making it difficult for operating workers to perform daily maintenance.

[0008] 5. The drainage problem of the fully underground sewage treatment plant is extremely prominent. According to the requirements of the specifications and traditional design ideas, the roof of the plant area is a large-area integral roof, with a large drainage confluence area and high drainage difficulty. If the roof is not drained in time, when it rains, the roof cover soil will be saturated with water, and the rainwater cannot be discharged. The saturated water in the cover soil will soak the plant roots, which will inevitably affect the landscape effect of the ground park.

[0009] 6. The traditionally designed landscape water glass channel is only suitable for improving the ground landscape effect, and cannot be organically combined with the roof drainage, underground HVAC and fire protection of the fully underground sewage treatment plant.

[0010] 7. High lighting energy consumption. Due to its inherent structural properties, the underground water treatment plant has insufficient underground lighting. Therefore, in the underground maintenance space, lighting needs to be provided 24 hours a day to ensure the safety of operating personnel and the convenience of equipment maintenance. However, this also brings a certain degree of energy waste. Given the current global exploration of new energy development, it is obviously not the best solution to consider the lighting needs of water plants by comprehensively considering electric lighting. Therefore, in the process of lighting design, it is necessary to comprehensively consider multiple solutions and try to use as much natural light as possible to directly enter the underground box to reduce energy consumption.

[0011] To sum up, how to create a new architectural form through a reasonable plan, effectively reduce the protruding stairwells, air shafts and other related auxiliary facilities of the fully underground sewage treatment plant, and reduce the damage to the ground landscape; at the same time, ensure the ventilation environment of the fully underground sewage treatment plant, improve the lighting effect of the fully underground sewage treatment plant, and combine it with the rainwater drainage system of the overall sewage treatment plant, and be able to meet the building design fire protection specifications and fire protection requirements, create a new comprehensive building system, and let the fully underground water treatment system take a step forward.

[0012] Patent document CN207620450U discloses a double-layer covered semi-underground sewage treatment plant layout structure, including a sewage treatment pool arranged in the soil layer below the ground, an overhead layer arranged above the ground, and a leisure area arranged on the overhead layer; the sewage treatment pool is entirely or mostly located below the ground level, and a first layer of covering area is arranged between the sewage treatment pool and the overhead layer, and the first layer of covering area separates the overhead layer from the sewage treatment pool; a second layer of covering area is arranged between the leisure area and the overhead layer, and the second layer of covering area separates the leisure area from the overhead layer, but the design still needs to design multiple stairwells as safety exits according to the building design fire protection specifications, which reduces the effective utilization rate of the building space.

[0038] 2. The present invention increases the sunken plaza. After natural light enters the sunken plaza through the glass, it enters the operating area through the doors and windows on both sides of the plaza, effectively improving the lighting brightness of the areas on both sides of the sunken plaza. Compared with the original scattered light well layout, the light is more concentrated, the glass lighting surface is larger, there are fewer structures that block the light, and it is more transparent. At the same time, scattered light wells are reduced, and the overall layout of the ground landscape can be more reasonably optimized. The lighting is optimized as a whole, the lighting effect of the sunken recycled water plant is improved, and the shortcomings of insufficient underground lighting caused by structural defects in the fully underground water treatment plant are effectively solved. The light sensitivity of the core area is increased sharply, which brings convenience to the equipment maintenance and daily inspections of factory operators, ensures the personal safety of operating personnel, and reduces the energy consumption of electric lighting, thereby reducing energy consumption and improving energy-saving effects.

[0039] 3. The Tianhe drainage system of the present invention is combined with the overall rainwater drainage system of the factory area. By combining it with the concept of "sponge city", the safety hazard of flood control and drainage in the factory area is reduced, and the rainwater that is difficult to discharge from the roof of the water plant is discharged to the outside through the process of rainwater drainage ditch-drainage board-rainwater drainage network-outside of the roof, which effectively prevents rainwater from gathering on the roof of the water plant and draining slowly, causing rainwater accumulation, and causing plant roots to be immersed in rainwater-saturated soil for a long time, causing rot.

[0040] 4. The present invention adds recycled water to the pool to demonstrate a high-quality recycled water system, and combines it with popular science education. Standing on the sunken square, the recycled water flowing in the pool above the head gives people a feeling of integration of man and nature. A sound system of water science popularization is established to show the results of environmentally friendly water treatment to the people, popularize the knowledge of environmentally friendly water treatment for young people, and root the concept of environmental protection in their hearts. It not only demonstrates the economic benefits of the fully underground sewage treatment plant, but also drives the benefits of the entire society. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0053] In order to solve the problems of lighting, HVAC, landscaping, drainage, etc. of the fully underground water plant, on the basis of meeting the requirements of fire protection regulations, other professional contents are integrated into it to form a comprehensive system, and the structure of the sunken square 15 in the architectural form is combined with the structure of the underground water plant. The present invention provides a comprehensive system suitable for a fully underground water plant. The fully underground water plant described in the present invention includes a fully underground sewage treatment plant, a fully underground recycled water plant and other underground water treatment devices, including a sunken square 15 and multiple water plant partitions 16, each of the water plant partitions 16 is connected to the sunken square 15. According to the actual water treatment requirements, multiple water plant partitions 16 can be set separately, or multiple water plant partitions 16 can be connected into one to meet the requirements of water treatment production.

[0054] Furthermore, the number of the sunken plazas 15 is one or more, which is specifically determined according to the number of water plant partitions 16 and the area of ​​the region. When the number of water plant partitions 16 is large and the area is large, and one sunken plaza 15 cannot meet the safety requirements, the number of sunken plazas 15 is increased according to the actual situation. The sunken plaza 15 is provided with a light transmission system, a ventilation system and a water drainage system. The light transmission system is arranged at the top of the sunken plaza 15, the water drainage system is arranged along the circumference of the sunken plaza 15, and the ventilation system enables external air to be replenished into the water plant partitions 16 through the sunken plaza 15.

[0055] Specifically, Figure 1 As shown, the light-transmitting system includes a glass light-transmitting plate 1, and external sunlight can be irradiated to the bottom of the sunken square 15 through the glass light-transmitting plate 1, wherein the part of the glass light-transmitting plate 1 exposed to the ground is provided with a pool edge along the circumference, and the pool edge and the glass light-transmitting plate 1 together form a pool. After the recycled water treated by the reclaimed water plant is introduced into the pool at the top of the sunken square 15, when viewed from the ground, the lighting corridor ripples with the waves on the ground of the square. When standing inside the water plant and looking up, the flowing water glass looks like a river flowing in the air, so this glass channel system is called "Sky River". Sunlight shines through the flowing water glass and sprinkles on the sunken square 15, so that the underground sewage treatment system and the ground ecological landscape system are organically combined, which makes people happy physically and mentally, and can fully display the special landscape of the underground reclaimed water plant, which is pleasing to the eye.

[0056] Specifically, Figure 1 As shown, in a preferred example, the area of ​​the glass translucent plate 1 is equal to the bottom area of ​​the sunken plaza 15, and the water level in the pool is not higher than 200㎜, which can not only allow the optical fiber to smoothly irradiate the bottom of the sunken plaza 15, but also produce the effect of a sky river.

[0057] Furthermore, the water drainage system includes a pool overflow pipe 5 and a top plate covering layer 7, one end of the pool overflow pipe 5 is connected to the pool through the pool edge, and the other end of the pool overflow pipe 5 extends above the top plate covering layer 7, and the bottom of the top plate covering layer 7 is the water plant top plate 8; when the water level of the pool reaches the connection between the pool overflow pipe 5 and the pool, the water flows into the top plate covering layer 7 through the pool overflow pipe 5. In actual applications, when it rains heavily or rainstorms, in order to prevent the instantaneous surge in water volume from affecting the load of the Tianhe, a pool overflow pipe 5 is added. When the water volume surges, the water in the Tianhe flows to the top plate covering layer 7 on both sides, such as Figure 1 As shown, 11 is the water flow direction of the pool overflow pipe 5.

[0058] Specifically, Figure 1 , Figure 2As shown, the water drainage system further includes a drainage ditch drain pipe 6, a box 12 and a drainage board 13. The water flowing into the top plate covering layer 7 enters the drainage board 13. The drainage board 13 is connected to the drainage ditch drain pipe 6. The drainage ditch drain pipe 6 extends to the outside of the box 12. In a preferred example, the water flowing into the top plate covering layer 7 penetrates into the drainage board 13 through the grass-planted ditch and permeable paving bricks on the top plate 8 of the water plant. The water on the drainage board 13 then enters the drainage ditch drain pipe 6 through multiple channels connected to the drainage ditch drain pipe 6 and finally flows to the outside of the box 12.

[0059] Specifically, Figure 1 As shown, the water drainage system also includes a drain ditch 4, which is arranged at the bottom of the ventilation channel 17 on both sides of the pool. A drain ditch grate 2 is arranged on the top of the drain ditch 4. The drain ditch 4 is connected to the drain ditch drain pipe 6. The drain ditch drain pipe 6 is provided with a slope. The drain ditch drain pipe 6 is connected to the bottom of the drain ditch 4, so that the water in the drain ditch 4 can flow smoothly to the outside of the box 12 through the drain ditch drain pipe 6, wherein the slope can be set to 0.1-0.5%.

[0060] It should be pointed out that the water on the drain board 13 flowing to the outside of the box body 12 through the drain ditch drain pipe 6 does not conflict with the water in the drain ditch 4 flowing to the outside of the box body 12 through the drain ditch drain pipe 6. Due to the drainage effect of the drain ditch drain pipe 6, the water on the drain board 13 and the water in the drain ditch 4 can eventually be diverted.

[0061] Specifically, Figure 1 As shown, the ventilation system includes ventilation louvers 3 and a fan, and the fan is installed in the water plant partition 16. Ventilation ducts 17 are provided on both sides of the top of the sunken plaza 15, and the ventilation louvers 3 are installed on the ventilation ducts 17. In a preferred example, the ventilation louvers 3 are installed on the wall on one side of the drainage ditch 4.

[0062] Furthermore, a safety exit 9 is provided on the side of the sunken plaza 15, and the water plant partition 16 is connected to the sunken plaza 15 through the safety exit 9. When the fan is started, the air inside the water plant partition 16 is sucked out, and the pressure inside the water plant partition 16 is lower than the air pressure on the ground. The external airflow enters the sunken plaza 15 through the ventilation duct 17 and the ventilation louver 3, and then enters the water plant partition 16 through the safety exit 9 to realize air circulation. The air flow direction is as follows: Figure 1 As shown in 10. In a preferred embodiment, the safety exit 9 adopts a Class A fireproof rolling shutter door.

[0063] Specifically, Figure 1As shown, the bottom end of the ventilation louver 3 is higher than the top surface of the drainage ditch 4, and a louver frame and a plurality of louver blades are provided on the ventilation louver 3. The plurality of louver blades are installed on the louver frame at laterally intervals, and the plurality of louver blades are arranged tilted, wherein the side of the louver blade close to the drainage ditch 4 faces downward, and the side of the louver blade close to the sunken plaza 15 faces upward, and the laterally tilted setting of the louver blades effectively plays a role in preventing rain and water.

[0064] The present invention designs a sunken plaza 15 in the core area of ​​the fully underground water plant that meets the fire protection regulations. Different water plant partitions 16 after separation lead to outdoor open spaces such as the sunken plaza 15. The horizontal distance between the nearest edges of any two water plant partitions (16) leading to the same sunken plaza (15) is not less than 13m; the outdoor open space shall not be used for other commercial purposes or purposes that may cause the spread of fire except for the evacuation of personnel, and the net area used for evacuation shall not be less than 169m 2 .

[0065] Furthermore, at least one evacuation staircase leading directly to the ground is provided in the outdoor open space such as the sunken plaza 15. When the fire compartment connected to the sunken plaza needs to use the sunken plaza for evacuation, the total clear width of the evacuation staircase should not be less than the total clear width of the design evacuation from any water plant partition 16 to the outdoor open space;

[0066] When vents are set up on all sides, the openings should be evenly arranged, the area of ​​the openings should not be less than 25% of the floor area of ​​the space, and the opening height should not be less than 1.0m; when shutters are set up on the openings, the effective smoke exhaust area of ​​the shutters can be calculated as 60% of the shutter ventilation area.

[0067] Specifically, in addition to being connected to the sunken plaza 15 via the safety exit 9, each of the water plant partitions 16 is also connected to at least one adjacent water plant partition 16 via the safety exit 9. Figure 2 FIG. 1 is an embodiment of the present invention. After the sunken plaza 15 is built in the underground core area of ​​the water plant, Figure 1 As shown, underground or semi-underground plant buildings include underground or semi-underground basements. When multiple fire compartments (i.e., the water plant compartment 16) are arranged adjacent to each other and separated by fire walls, each fire compartment can use the Class A fire door on the fire wall leading to the adjacent fire compartment as the second safety exit, but each water plant compartment 16 must have at least one independent safety exit directly to the outdoors. The sunken plaza 15 is identified as the outdoors, so that each fire compartment can reduce one staircase leading to the ground, and directly entering the sunken plaza 15 is regarded as entering a safe area, which simplifies the entire building design and reduces construction costs.

[0068] The designed top opening area of ​​the sunken plaza 15 is not less than 25% of the ground area of ​​the space. Ventilation louvers 3 are added on both sides of the upper part of the sunken plaza 15. The ventilation louvers 3 are set at a height of more than 1m from the ground. The side view of the ventilation louver 3 installation wind tunnel is long and narrow as a whole, and the louver blades are separate rectangles. In a preferred example, the rectangular size is 3600mmX900mm, and the effective ventilation area of ​​each rectangular louver is 60%. According to calculations, the actual ventilation area is greater than 25% of the area of ​​the sunken plaza 15.

[0069] The top of the sunken square 15 adopts a full-section glass skylight with a large lighting area. After natural light enters the sunken square 15 through the glass, it enters the operation area through the doors and windows on both sides of the square, effectively improving the lighting brightness of the areas on both sides of the sunken square 15. Compared with the original scattered light well layout, this layout is more centralized, with a larger glass lighting surface, fewer structures that block light, and more transparent. At the same time, by reducing scattered light wells, the overall layout of the ground landscape can be more reasonably optimized.

[0070] This embodiment reduces the number of auxiliary facilities such as stairwells and air shafts protruding from the ground, synergistically improves the ground landscape effect, and ensures the ventilation environment of the fully underground water treatment plant. More importantly, under the condition of meeting the building fire protection regulations and fire protection requirements, the ground landscape of the fully underground water plant and the underground sewage treatment system are regarded as an integrated ecological complex, and the upper and lower layers are organically combined through the "Sky River". The ventilation louvers 3 on both sides of the top "Sky River" are provided with drainage ditches 4, and slopes are set in the drainage ditches 4. The drainage ditches 4 on both sides are provided with drainage pipes, which lead to both sides along the top plate of the sunken sewage treatment plant, and drain the rainwater in the drainage ditches 4 on both sides of the Sky River to the outside of the box 12. At the same time, this drainage pipe is combined with the drainage board on the top plate, so that the rainwater collected in the drainage board is discharged to the outside of the top plate through this rainwater pipe, effectively preventing rainwater from collecting on the top plate, and slow drainage causing rainwater siltation, which causes plant roots to be soaked for a long time and cause rot.

[0071] Depend on Figure 3 It can be seen that according to Figure 1 The "Sky River" structural form shown can meet all the requirements of the building design fire protection code for the sunken plaza 15, so the sunken plaza 15 is understood as an outdoor area. The staff 14 in the water plant partition 16 escape from the safety exit 9 into the sunken plaza 15, which is regarded as entering the outdoor safe area, and then go to the ground through the evacuation stairs of the safety exit of the sunken plaza 15.

[0072] In the description of the present application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0073] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present invention.
