Description

Technical Field

[0001] The utility model relates to a sinking equipment foundation for installing a cooling tower, belonging to the technical field of equipment installation foundation structure. Background Art

[0002] Existing centralized air-conditioning systems in civil buildings, while using ground-source heat pumps as cold and heat sources, often need to be equipped with chillers and cooling towers as backup cold and heat sources to help the soil achieve a balance between heat intake and heat release. Cooling towers, as heat dissipation facilities for backup cold and heat sources, are large in size, noisy, and have a short operating season. In residential projects that use centralized air-conditioning systems, the planned land area is limited, but the cooling tower occupies a large space, making the site selection and landscape design of the cooling tower more difficult.

[0003] Taking a 400T / H closed cooling tower as an example, the net height of the equipment is 4650mm, and the concrete foundation needs to be 800mm high. In addition to fixing the cooling tower, the concrete foundation also needs to consider the necessary space for installing water pipes and repairing the water collection tray on the lower side of the cooling tower; in addition, in order to prevent the operating noise of the cooling tower from spreading to adjacent buildings, a soundproof cover is often required on the outside of the cooling tower to prevent noise pollution; the soundproof cover is surrounded and topped by sound-absorbing louvers or grilles, and the top of the soundproof cover needs to be 1250mm away from the top of the cooling tower for later maintenance space. At the same time, the top of the soundproof cover itself is 1500mm high. Therefore, after the cooling tower and the soundproof cover are installed, the overall height protruding from the ground reaches 8200mm, which seriously affects the appearance, landscape, and field of vision, and even affects the sunlight on the lower floors of the rear buildings. Utility Model Content

[0004] In order to reduce the overall height of a cooling tower and a sound insulation cover protruding from the ground after installation, the utility model provides a sunken equipment foundation for installing a cooling tower.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A sunken equipment foundation for installing a cooling tower comprises a basement roof, an equipment installation area is arranged on the top of the basement roof, a plurality of upturned beams are arranged on the basement roof within the equipment installation area, and the plurality of upturned beams are used to install and fix the cooling tower; a covering soil layer is arranged on the basement roof around the equipment installation area, and the top of the covering soil layer is higher than the top of the upturned beam.

[0007] As a preferred embodiment of the present invention, the height of the upwardly turned beam protruding from the basement top plate is 800 mm.

[0008] As a preferred embodiment of the present invention, the top surface of the covering soil layer is on the same horizontal plane as the bottom of the cooling tower air inlet louvers.

[0009] As a preferred embodiment of the present invention, no hanging beam is provided at the bottom of the basement top plate corresponding to the equipment installation area.

[0010] As a preferred embodiment of the present invention, a sump is provided on the top plate of the basement within the equipment installation area.

[0011] The utility model is beneficial in that:

[0012] The structural beams of the basement roof are turned upside down so that the turned-up beams can serve as the concrete foundation of the cooling tower, bearing the weight of the cooling tower and fixing the cooling tower, thereby reducing the height of the cooling tower above the outdoor floor and reducing the impact of the cooling tower on appearance, landscape, vision and sunshine. The area where the cooling tower is located (i.e. the equipment installation area) is no longer equipped with a covering soil layer, which reduces the amount of outdoor covering soil backfill and the load on the basement roof. At the same time, the materials and processes for making the concrete foundation of the cooling tower on the covering soil layer are eliminated, thus simplifying the construction process, saving construction costs and having good construction promotion value.

[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 As shown, the present embodiment is a sunken equipment foundation for installing a cooling tower, comprising a basement roof 1, an equipment installation area 2 is arranged on the top of the basement roof 1, a plurality of upturned beams 3 are arranged on the basement roof 1 within the equipment installation area 2, and the plurality of upturned beams 3 are used to install a fixed cooling tower 4; in the present embodiment, the number of the upturned beams 3 is three, and in actual application, the number of the upturned beams 3 can be appropriately increased according to actual conditions; a covering layer 5 is arranged on the basement roof 1 around the equipment installation area 2, and the top of the covering layer 5 is higher than the top of the upturned beam 3.

[0021] In this embodiment, the height of the upturned beam 3 protruding from the basement roof 1 is 800 mm; in this embodiment, the thickness of the covering layer 5 is 1500 mm, and the top surface of the covering layer 5 is on the same horizontal plane as the bottom of the air inlet louver of the cooling tower 4.

[0022] In this embodiment, no hanging beam 6 is provided at the bottom of the basement ceiling 1 corresponding to the equipment installation area 2 .

[0023] In this embodiment, a sump 7 is provided on the basement ceiling 1 within the equipment installation area 2 .

[0024] like Figure 2 As shown, the net height of the traditional cooling tower 4 is 4650mm. The concrete foundation 10 of the traditional cooling tower 4 is set above the covering layer 5 to fix the cooling tower 4. The height of the concrete foundation 10 of the traditional cooling tower 4 is 800mm. The space on the lower side of the cooling tower 4 also needs to be considered for the installation of the cooling tower supply and return pipes 8 and the maintenance of the cooling tower water collecting pan 9. In addition, in order to prevent the operating noise of the cooling tower 4 from spreading to adjacent buildings, a soundproof cover 11 is often required to prevent noise pollution. The four sides of the soundproof cover 11 are sound-absorbing louvers or grilles. The top of the soundproof cover 11 needs to be 1250mm away from the top of the cooling tower 4 for later maintenance space. In addition, the top of the soundproof cover 11 itself is 1500mm high. Therefore, after the installation of the traditional cooling tower 4 and the soundproof cover 11, it is 8200mm higher than the outdoor floor (i.e., the covering layer 5), which seriously affects the appearance, landscape, and vision, and even affects the sunlight at the lower floors of the rear buildings.

[0025] The basement top plate 1 below the concrete foundation 10 of the traditional cooling tower 4 is usually provided with a lower hanging beam 6. Affected by the lower hanging beam 6, the local net height of the basement is 3000mm. The lower hanging beam 6, that is, the top surface of the beam is consistent with the top surface elevation of the cast-in-place slab, and the upper flip beam 3 is the bottom surface of the beam is consistent with the bottom surface elevation of the cast-in-place slab. In popular terms, the beam under the slab is called the lower hanging beam 6, and the beam on the slab is called the upper flip beam 3. Taking a residential project as an example, the height of the lower hanging beam 6 of the basement top plate 1 is about 800-1000m m, after the lower hanging beam 6 is changed to the upper flip beam 3, the part of the upper flip beam 3 protruding from the basement top plate 1 can just be used as the equipment foundation of the cooling tower 4. At this time, compared with the traditional cooling tower 4 concrete foundation 10 set on the covering layer 5, the cooling tower 4 using the upper flip beam 3 as the equipment foundation is installed in a sunken manner, which can make full use of the 1500mm thick covering layer 5, so that after the cooling tower 4 and the sound insulation cover 11 are installed, the height above the outdoor floor (i.e., the covering layer 5) is reduced by 1500mm.

[0026] like Figure 1As shown, in this embodiment, the structural beam of the basement top plate 1 is turned up to form an upturned beam 3, so that the upturned beam 3 also serves as the concrete foundation of the cooling tower 4, bears the weight of the cooling tower 4 and plays a role in fixing the cooling tower 4. The area where the cooling tower 4 is located (i.e., the equipment installation area 2) is no longer provided with a covering layer 5, thereby reducing the backfill amount of the covering soil; the cooling tower 4 is directly arranged on the upturned beam 3 of the basement top plate 1, thereby reducing the height of the cooling tower 4 above the outdoor floor (i.e., the covering layer 5), thereby effectively utilizing the net height of the covering soil; in order to prevent water accumulation in the equipment installation area 2 on rainy days, a sump 7 is arranged on the basement top plate 1 to drain the water accumulated in the equipment installation area 2 on rainy days; the use of the upturned beam 3 as the equipment foundation can save the traditional cooling tower 4 concrete foundation 10 The casting materials and the manufacturing process reduce the covering soil and load of the basement top plate 1; after the cooling tower 4 and the sound insulation cover 11 are installed, they are 6700mm higher than the outdoor floor (i.e., the covering soil layer 5). Compared with the conventional cooling tower 4 concrete foundation 10, the overall height of the cooling tower 4 and the sound insulation cover 11 above the outdoor floor (i.e., the covering soil layer 5) is reduced by 1500mm; moreover, the air inlet louvers of the cooling tower 4 are also higher than the horizontal plane of the covering soil layer 5, and the air inlet of the cooling tower 4 is not affected; at the same time, no lower hanging beam 6 is arranged on the basement top plate 1 corresponding to the equipment installation area 2, therefore, the local clear height of the basement corresponding to the equipment installation area 2 is 3800mm, and compared with the conventional cooling tower 4 concrete foundation 10, the local clear height of the basement is increased by 800mm.

[0027] In this embodiment, the structural beams of the basement roof are turned upside down, so that the turned-up beams also serve as the concrete foundation of the cooling tower, bear the weight of the cooling tower and play a role in fixing the cooling tower, thereby reducing the height of the cooling tower above the outdoor floor and reducing the impact of the cooling tower on the appearance, landscape, field of vision and sunshine; the area where the cooling tower is located (i.e., the equipment installation area) is no longer provided with a covering soil layer, thereby reducing the amount of outdoor covering soil backfill and the load on the basement roof; at the same time, the materials and process for making the concrete foundation of the cooling tower on the covering soil layer are eliminated, thereby simplifying the construction process, saving construction costs and having good construction promotion value.
