[0047] This application also proposes a cooling tower manufactured using the cooling tower design method described above.

[0048] In this embodiment, the design method and construction personnel determine the first and second bearing zones in the foundation based on the bearing capacity of the foundation. The bearing capacity of the foundation in the first bearing zone differs from that in the second bearing zone, and the bearing capacity of the foundation in the first bearing zone is greater than that in the second bearing zone. By casting piles in the second bearing zone and inserting at least part of the piles into the foundation of the second bearing zone, the bearing capacity of the foundation in the second bearing zone can be increased, and the difference between the bearing capacities of the foundations in the first and second bearing zones can be reduced. When a water tank is formed on the surface of the foundation, the piles inserted into the foundation of the second bearing zone can support the water tank, ensuring that the settlement value of the water tank in the second bearing zone is within the target range and reducing the difference between the settlement values ​​of the water tank in the first and second bearing zones; thereby reducing the risk of the final cooling tower tilting due to the excessive difference in bearing capacity between the water tank in the first and second bearing zones.

[0049] In the above process, since no foundation piles are cast in the first bearing zone with stronger bearing capacity, foundation piles are only cast in the second bearing zone with weaker bearing capacity. This reduces the number of foundation piles required, ensuring that foundation piles are installed in areas of the foundation where bearing capacity needs to be strengthened, thus reducing the waste rate of foundation piles. In summary, the cooling tower design method and cooling tower in this embodiment, by casting foundation piles only in the second bearing zone with weaker bearing capacity in the foundation, can reduce the total number of foundation piles, reduce the amount of foundation pile casting work, and reduce the waste rate of foundation piles.

[0072] Please see Figures 1 to 3 , Figure 1 A main sectional view of a cooling tower and its foundation according to an embodiment of this application is shown. An embodiment of this application provides a design method for a cooling tower 100, comprising:

[0073] S100: Based on the bearing capacity of the foundation 200, determine the first bearing zone 210 and the second bearing zone 220 of the foundation 200, wherein the bearing capacity of the first bearing zone 210 is greater than that of the second bearing zone 220.

[0074] S200: Pile 230 is poured in the second bearing zone 220, and at least a portion of the pile 230 is inserted into the foundation 200 of the second bearing zone 220.

[0075] S400: A water tank 110 is formed on the surface of the foundation 200. A portion of the bottom wall 111 of the water tank 110 is located in the second bearing area 220 and is supported on the ground pile 230. Another portion of the bottom wall 111 is located in the first bearing area 210 and is supported on the foundation 200.

[0076] In the design method of the cooling tower 100 in this embodiment, the construction personnel determine the first bearing zone 210 and the second bearing zone 220 in the foundation 200 based on the bearing capacity of the foundation 200. The bearing capacity of the foundation 200 in the first bearing zone 210 is different from that in the second bearing zone 220, and the bearing capacity of the foundation 200 in the first bearing zone 210 is greater than that in the second bearing zone 220. By casting foundation piles 230 in the second bearing zone 220 and inserting at least a portion of the foundation piles 230 into the foundation 200 of the second bearing zone 220, the bearing capacity of the foundation 200 in the second bearing zone 220 can be increased, thereby reducing the difference between the bearing capacity of the foundation 200 in the first bearing zone 210 and the bearing capacity of the foundation 200 in the second bearing zone 220. When a water tank 110 is formed on the surface of the foundation 200, the piles 230 inserted into the foundation 200 in the second bearing area 220 can support the water tank 110 to ensure that the settlement value of the water tank 110 in the second bearing area 220 is within the target range, and reduce the difference between the settlement value of the water tank 110 in the first bearing area 210 and the settlement value of the water tank 110 in the second bearing area 220; thereby reducing the risk that the final cooling tower 100 will tilt due to the large difference in bearing capacity between the water tank 110 in the first bearing area 210 and the second bearing area 220.

[0077] In the above process, since the first bearing zone 210, which has a stronger bearing capacity, does not have foundation piles 230, the foundation piles 230 are only poured in the second bearing zone 220, which has a weaker bearing capacity. This reduces the number of foundation piles 230, ensuring that foundation piles 230 are installed in the areas of the foundation 200 where the bearing capacity needs to be strengthened, thus reducing the waste rate of foundation piles 230. In summary, the design method of the cooling tower 100 in this embodiment, by pouring foundation piles 230 only in the second bearing zone 220, which has a weaker bearing capacity in the foundation 200, can reduce the total number of foundation piles 230, reduce the amount of work involved in pouring foundation piles 230, and reduce the waste rate of foundation piles 230.

[0078] It should be further explained that the first bearing zone 210 can be an area in the foundation 200 where the rock strata are shallow or where there are no karst caves; the second bearing zone 220 can be an area in the foundation 200 where the rock strata are deep or where there are karst caves.

[0079] Please see Figures 1 to 4In some embodiments, the first bearing area 210 includes multiple components, and after the step of forming the water pool 110 on the surface of the foundation 200, the method further includes:

[0080] S500: A wall structure 120 is formed on the side of the bottom wall 111 of the pool 110 away from the foundation 200; the wall structure 120 includes a plurality of walls 121, which are arranged in multiple rows along a first direction; at least one row of walls 121 includes a plurality of first walls 121-1 arranged in a column along a second direction; the first direction, the second direction and the thickness direction of the bottom wall 111 of the pool 110 intersect each other.

[0081] The first wall 121-1 includes a first wall panel 121-1-1 and a plurality of first wall pillars 121-1-2, the plurality of first wall pillars 121-1-2 being arranged along a first direction; at least one of the second load-bearing areas 220 is provided with a first wall pillar 121-1-2; the first wall panel 121-1-1 in the first wall 121-1 is located on the side of the corresponding first wall pillar 121-1-2 away from the foundation 200.

[0082] In this embodiment, the design method of the cooling tower 100 includes a plurality of first walls 121-1 arranged in a row along the second direction. Since there is a gap between adjacent first walls 121-1, construction workers can place the target equipment within the gap between adjacent first walls 121-1. The target equipment is then shielded by the first wall panels 121-1-1 located on opposite sides of the target equipment along the second direction. Optionally, the target equipment is the fan 130 of the cooling tower 100.

[0083] Furthermore, since the first wall 121-1 includes multiple first wall pillars 121-1-2, at least one of the second bearing areas 220 is provided with a first wall pillar 121-1-2; thus, the area where the bottom wall 111 of the pool 110 contacts the first wall pillar 121-1-2 can be supported by the ground piles 230 within the second bearing area 220 where the first wall pillar 121-1-2 is located. By supporting the bottom wall 111 of the pool 110 with the ground piles 230 within the second bearing area 220 where the first wall pillar 121-1-2 is located, the settlement that occurs in the area where the bottom wall 111 of the pool 110 contacts the first wall pillar 121-1-2 under the compression of the first wall pillar 121-1-2 can be reduced; ensuring that the foundation 200 within the second bearing area 220 where the first wall pillar 121-1-2 is located effectively supports the pool 110.

[0084] Please see Figures 1 to 4 In some embodiments, after the second bearing zone 220 is filled with the foundation pile 230, the following steps are included:

[0085] S300: A bearing platform 240 is provided at the end of the pile 230 in the second bearing area 220 away from the foundation 200. The outer contour of the orthographic projection of the bearing platform 240 on the foundation 200 coincides with the outer contour of the corresponding second bearing area 220, or surrounds the outer contour of the corresponding second bearing area 220.

[0086] In this embodiment, the cooling tower 100 is designed such that the piles 230 in the second bearing area 220 contact the bottom wall 111 of the water tank 110 via the bearing platform 240. The outer contour of the orthographic projection of the bearing platform 240 onto the foundation 200 coincides with or surrounds the outer contour of the corresponding second bearing area 220; this increases the contact area between the bearing platform 240 and the bottom wall 111 of the water tank 110, facilitating better support of the bearing platform 240 for the bottom wall 111 of the water tank 110.

[0087] It should be noted that the support platform 240 can be formed by casting, specifically by casting concrete.

[0088] Please see Figures 1 to 4 In some embodiments, a first gap 123 is provided between two adjacent walls 121 along a first direction. Specifically, along the first direction, the support platforms 240 located on opposite sides of the orthographic projection of the first gap 123 onto the foundation 200, and closest to the first gap 123, within the two second support areas 220, are constructed as two parts of the same support plate.

[0089] In this embodiment, the cooling tower 100 is designed such that the support platforms 240 within the two second support zones 220 closest to the first gap 123 are constructed as two parts of the same support plate. Thus, the two first wall columns 121-1-2 located on opposite sides of the first gap 123 along the first direction and closest to the first gap 123 are supported by the same support plate. This support plate ensures that the bottom wall 111 of the water tank 110 experiences substantially the same settlement value in the contact area with the two first wall columns 121-1-2 supported by the support plate. This prevents the bottom wall 111 of the water tank 110 from experiencing significantly different settlement values ​​in the contact area with the two first wall columns 121-1-2 supported by the support plate, which could lead to tensile cracking in the area between the two first wall columns 121-1-2.

[0090] Please see Figures 1 to 4 In some embodiments, each row of walls 121 includes a plurality of first walls 121-1, with a second gap 124 between adjacent first walls 121-1. After the step of forming the pool 110 on the surface of the foundation 200, the following steps are included:

[0091] S600: Multiple support columns (not shown in the figure) are formed on the side of the bottom wall 111 of the pool 110 away from the foundation 200.

[0092] The support columns are formed within the second gap 124; multiple support columns correspond one-to-one with a portion of the second bearing area 220; the orthographic projection of each support column on the foundation 200 is located within the corresponding second bearing area 220; the support columns and the first wall columns 121-1-2 correspond to different second bearing areas 220 respectively.

[0093] S700: Fan 130 is installed on the support column.

[0094] In this embodiment, the design method of the cooling tower 100 allows the support columns to support the fan 130 within the second gap 124, thereby creating a gap between the fan 130 and the bottom wall 111 of the water tank 110. Furthermore, since multiple support columns correspond one-to-one with portions of the second bearing area 220, the orthographic projection of each support column onto the foundation 200 lies within its corresponding second bearing area 220. Thus, the area where the bottom wall 111 of the water tank 110 contacts the support columns is supported by the ground piles 230 within the second bearing area 220 where the support columns are located. By supporting the bottom wall 111 of the water tank 110 with the ground piles 230 within the second bearing area 220 where the support columns are located, the settlement occurring in the area where the bottom wall 111 of the water tank 110 contacts the support columns under the pressure of the support columns can be reduced; ensuring that the foundation 200 within the second bearing area 220 where the support columns are located effectively supports the water tank 110.

[0095] Please see Figures 1 to 4 In some embodiments, the step of forming a water tank 110 on the surface of the foundation 200 includes:

[0096] S410: A first region 111-1 is formed on the surface of the foundation 200, which is the bottom wall 111 of the pool 110.

[0097] S420: A second region 111-2 of the bottom wall 111 of the pool 110 is formed on the surface of the foundation 200. The first region 111-1 and the second region 111-2 are arranged along a first direction;

[0098] S430: A first post-cast strip 111-3 is formed between the first region 111-1 and the second region 111-2.

[0099] In this embodiment, the design method of the cooling tower 100 involves a first post-cast strip 111-3 that separates the first region 111-1 and the second region 111-2 of the bottom wall 111 of the cast-in-place water tank 110. This allows sufficient time for the initial settlement of the areas where the foundation 200 contacts the bottom wall 111 of the water tank 110 in the first region 111-1 and the areas where it contacts the bottom wall 111 of the water tank 110 in the second region 111-2. Subsequently, construction workers will pour concrete into the first post-cast strip 111-3 to fill the gaps between the bottom walls 111 of the water tank 110 in the first region 111-1 and the bottom walls 111 of the water tank 110 in the second region 111-2. The concrete poured in the first post-cast strip 111-3 can connect the bottom wall 111 of the pool 110 in the first region 111-1 with the bottom wall 111 of the pool 110 in the second region 111-2, and together with the first region 111-1 and the second region 111-2 of the bottom wall 111 of the pool 110 formed by the pouring, it constitutes the bottom wall 111 of the pool 110.

[0100] Through the above process, the risk of the bottom wall 111 of the pool 110 breaking between the first region 111-1 and the second region 111-2 due to the different settlement values ​​of the area where the foundation 200 contacts the bottom wall 111 of the pool 110 in the first region 111-1 and the area where the bottom wall 111 of the pool 110 in the second region 111-2 contacts the pool 110 can be reduced.

[0101] Please see Figures 1 to 4 In some embodiments, the first region 111-1 includes multiple regions, and the second region 111-2 includes multiple regions. The multiple first regions 111-1 and the multiple second regions 111-2 are arranged alternately along a first direction, and at least one first region 111-1 and an adjacent second region 111-2 form a first post-cast strip 111-3; the first post-cast strip 111-3 extends along a second direction.

[0102] In the design method of the cooling tower 100 in this embodiment, since at least one first region 111-1 and the adjacent second region 111-2 form a first post-pouring strip 111-3, the risk of breakage between at least one first region 111-1 and the adjacent second region 111-2 of the bottom wall 111 of the pool 110 can be reduced.

[0103] Please see Figures 1 to 4 In some embodiments, after the step of forming a first post-cast strip 111-3 between the first region 111-1 and the second region 111-2, the method further includes:

[0104] S440: A first sidewall 112-1 is formed on each of the opposite sides of the bottom wall 111 of the pool 110 along the first direction.

[0105] S450: Two second sidewalls 112-2 are formed on the side of the bottom wall 111 of the pool 110 in the first region 111-1 that is away from the foundation 200, and on the side of the bottom wall 111 of the pool 110 in the second region 111-2 that is away from the foundation 200, respectively.

[0106] The first side wall 112-1 and the second side wall 112-2 together form the side wall 112 of the pool 110;

[0107] S460: Along the first direction, a second post-cast strip 112-3 is formed between two adjacent second sidewalls 112-2.

[0108] The second post-cast strip 112-3 extends along the thickness direction of the bottom wall 111 of the pool 110 and connects with the first post-cast strip 111-3 located between two adjacent second side walls 112-2.

[0109] In the design method of the cooling tower 100 in this embodiment, the second post-pouring strip 112-3 separates the first side wall 112-1 on the bottom wall 111 of the water tank 110 in the first region 111-1 from the first side wall 112-1 on the bottom wall 111 of the water tank 110 in the second region 111-2. The construction workers will then pour concrete into the second post-pouring strip 112-3 to fill the gap between the first side wall 112-1 on the bottom wall 111 of the water tank 110 in the first region 111-1 and the first side wall 112-1 on the bottom wall 111 of the water tank 110 in the second region 111-2. The concrete poured in the second post-cast strip 112-3 can connect the first side wall 112-1 on the bottom wall 111 of the pool 110 in the first region 111-1 with the first side wall 112-1 on the bottom wall 111 of the pool 110 in the second region 111-2; and together with the first side wall 112-1 on the bottom wall 111 of the pool 110 in the first region 111-1 and the first side wall 112-1 on the bottom wall 111 of the pool 110 in the second region 111-2, they together form the opposite sides of the side wall 112 of the pool 110 along the second direction.

[0110] Through the above process, the risk of fracture between the first sidewall 112-1 on the bottom wall 111 of the pool 110 in the first region 111-1 and the first sidewall 112-1 on the bottom wall 111 of the pool 110 in the second region 111-2 can be reduced due to the different settlement values ​​in the area where the foundation 200 contacts the bottom wall 111 of the pool 110 in the first region 111-1 and the bottom wall 111 of the pool 110 in the second region 111-2.

[0111] Please see Figures 1 to 4In some embodiments, the step of forming a wall structure 120 on the side of the bottom wall 111 of the pool 110 facing away from the foundation 200 further includes:

[0112] S510: A wall 121 is formed between the two second side walls 112-2 on the bottom wall 111 of the pool 110 in the first region 111-1, and between the two second side walls 112-2 on the bottom wall 111 of the pool 110 in the second region 111-2.

[0113] S520: Along the first direction, a second wall 122 is formed on the side of the two walls 121 furthest from the center of the bottom wall 111 of the pool 110, away from the adjacent wall 121.

[0114] The second wall 122 includes a second wall panel 122-1 and multiple second wall columns 122-2. The multiple second wall columns 122-2 are arranged along a second direction. The second wall panel 122-1 is located on the side of the second wall column 122-2 away from the foundation 200. The multiple second wall columns 122-2 correspond one-to-one with a portion of the second load-bearing area 220. The orthographic projection of each second wall column 122-2 on the foundation 200 is located within the corresponding second load-bearing area 220. The support column, the first wall column 121-1-2, and the second wall column 122-2 correspond to different second load-bearing areas 220.

[0115] In this embodiment, the design method of the cooling tower 100 involves two second wall panels 122-1 of the second enclosure walls 122, which, along a first direction, protect the fan located between two adjacent first enclosure walls 121-1. Since the second enclosure wall 122 includes multiple second wall pillars 122-2, each second wall pillar 122-2 corresponds one-to-one with a portion of the second load-bearing area 220; thus, the area where the bottom wall 111 of the water tank 110 contacts the second wall pillars 122-2 can be supported by the ground piles 230 within the second load-bearing area 220 where the second wall pillars 122-2 are located. By using the piles 230 within the second bearing area 220 where the second wall column 122-2 is located to support the bottom wall 111 of the water tank 110, the area in contact between the bottom wall 111 of the water tank 110 and the second wall column 122-2 can be reduced, thus reducing the settlement that occurs under the compression of the second wall column 122-2; and ensuring that the foundation 200 within the second bearing area 220 where the second wall column 122-2 is located effectively supports the water tank 110.

[0116] Please see Figures 1 to 4 In some embodiments, the step of mounting the fan 130 on the support column includes:

[0117] S710: A first number of fans 130 are installed in the second gap 124 of the wall 121 in the first area 111-1.

[0118] S720: A second number of fans 130 are installed in the second gap 124 of the wall 121 in the second area 111-2.

[0119] Among them, the fan 130 in the first region 111-1 and the fan 130 in the second region 111-2 are respectively located on the support column in the corresponding second gap 124; the first number and the second number are not equal.

[0120] In this embodiment, the design method of the cooling tower 100 differs in that the number of fans 130 installed in the second gap 124 of the wall 121 in the first region 111-1 is different from the number of fans 130 installed in the second gap 124 of the wall 121 in the second region 111-2. As a result, the wind force generated in the second gap 124 of the wall 121 in the first region 111-1 is different from the wind force generated in the second gap 124 of the wall 121 in the second region 111-2.

[0121] Please see Figures 1 to 4 In some embodiments, the first quantity is greater than the second quantity. Specifically, the thickness of the bottom wall 111 of the pool 110 in the first region 111-1 is the first value, and the thickness of the bottom wall 111 of the pool 110 in the second region 111-2 is the second value; the first value is greater than the second value.

[0122] In the design method of the cooling tower 100 in this embodiment, since the number of fans 130 installed in the second gap 124 of the wall 121 of the first region 111-1 is greater than the number of fans 130 installed in the second gap 124 of the wall 121 of the second region 111-2, the compressive force on the bottom wall 111 of the water tank 110 in the first region 111-1 is greater than the compressive force on the bottom wall 111 of the water tank 110 in the second region 111-2. By making the thickness of the bottom wall 111 of the pool 110 in the first region 111-1 greater than the thickness of the bottom wall 111 of the pool 110 in the second region 111-2, the load-bearing capacity of the bottom wall 111 of the pool 110 in the first region 111-1 can be improved, the shear resistance of the bottom wall 111 of the pool 110 in the first region 111-1 can be improved, and the risk of the bottom wall 111 of the pool 110 at the connection between the bottom wall 111 of the pool 110 in the first region 111-1 and the bottom wall 111 of the pool 110 in the second region 111-2 can be reduced.

[0123] In addition, it should be noted that since the thickness of the bottom wall 111 of the water tank 110 in the first region 111-1 is greater than the thickness of the bottom wall 111 of the water tank 110 in the second region 111-2, the amount of work required to pour the bottom wall 111 of the water tank 110 can be reduced, and the amount of concrete required to pour the bottom wall 111 of the water tank 110 can be reduced, thus reducing unnecessary waste.

[0124] In some embodiments, the bottom wall 111 of the pool 110 in the first region 111-1, facing away from the foundation 200, is flush with the bottom wall 111 of the pool 110 in the second region 111-2, facing away from the foundation 200. The side of the bottom wall 111 of the pool 110 in the first region 111-1 that is close to the foundation 200 is a first contact surface (not shown in the figure), and the side of the bottom wall 111 of the pool 110 in the second region 111-2 that is close to the foundation 200 is a second contact surface (not shown in the figure). A transition surface (not shown in the figure) is provided between the first contact surface and the second contact surface. Along the direction from the first contact surface to the second contact surface, the distance between the transition surface and the foundation 200 in the thickness direction of the foundation 200 gradually increases.

[0125] In some embodiments, the angle between the transition surface and the second contact surface is an obtuse angle. Optionally, the angle between the transition surface and the second contact surface is 150 degrees.

[0126] Please see Figures 1 to 4 In some embodiments, in the first region 111-1, τ1≥[τ], τ1=F1 / A1, A1=L*D1, τ1 is the shear stress on the bottom wall 111 of the pool 110 in the first region 111-1, and [τ] is the allowable shear stress of the material used to make the pool 110. Wherein, F1 is the weight of the enclosure wall 121 and the fan 130 in the first region 111-1, A1 is the cross-sectional area of ​​the bottom wall 111 of the pool 110 in the first region 111-1, L is the dimension of the bottom wall 111 of the pool 110 along the second direction, and D1 is the thickness of the bottom wall 111 of the pool 110 in the first region 111-1.

[0127] In the design method of the cooling tower 100 in this embodiment, since the shear stress τ1 on the bottom wall 111 of the water tank 110 in the first region 111-1 is greater than or equal to the allowable shear stress [τ] of the material used to make the water tank 110, the bearing capacity of the bottom wall 111 of the water tank 110 in the first region 111-1 can be improved, the shear resistance of the bottom wall 111 of the water tank 110 in the first region 111-1 can be improved, and the risk of the bottom wall 111 of the water tank 110 at the connection between the bottom wall 111 of the water tank 110 in the first region 111-1 and the bottom wall 111 of the water tank 110 in the second region 111-2 can be reduced.

[0128] Please see Figures 1 to 4In some embodiments, for the second region 111-2, τ2 ≥ [τ], τ2 = F2 / A2, A2 = L*D2, τ2 is the shear stress on the bottom wall 111 of the pool 110 in the second region 111-2, and [τ] is the allowable shear stress of the material used to make the pool 110. Wherein, F2 is the weight of the enclosure wall 121 and the fan 130 in the second region 111-2, A2 is the cross-sectional area of ​​the bottom wall 111 of the pool 110 in the second region 111-2, L is the dimension of the bottom wall 111 of the pool 110 along the second direction, and D2 is the thickness of the bottom wall 111 of the pool 110 in the second region 111-2.

[0129] In the design method of the cooling tower 100 in this embodiment, the shear stress τ2 on the bottom wall 111 of the water tank 110 in the second region 111-2 is greater than or equal to the allowable shear stress [τ] of the material used to make the water tank 110. In this way, the bearing capacity of the bottom wall 111 of the water tank 110 in the second region 111-2 can be improved, the shear resistance of the bottom wall 111 of the water tank 110 in the second region 111-2 can be improved, and the risk of the bottom wall 111 of the water tank 110 in the first region 111-1 breaking at the connection between the bottom wall 111 of the water tank 110 in the second region 111-2 and the bottom wall 111 of the water tank 110 in the first region 111-1 can be reduced.

[0130] Please see Figures 1 to 4 In some embodiments, the step of forming a wall 121 between two second side walls 112-2 on the bottom wall 111 of the pool 110 in the first region 111-1 includes: forming a plurality of first walls 121-1 arranged along a second direction between the two second side walls 112-2 on the bottom wall 111 of the pool 110 in the first region 111-1. A portion of the first wall posts 121-1-2 in the first region 111-1 are located within the corresponding first region 111-1, and another portion of the first wall posts 121-1-2 are located within the adjacent second region 111-2 of the corresponding first region 111-1.

[0131] Please see Figures 1 to 4 In some embodiments, the step of forming a wall 121 between two second side walls 112-2 on the bottom wall 111 of the pool 110 in the second region 111-2 includes: forming a plurality of first walls 121-1 arranged along a second direction between the two second side walls 112-2 on the bottom wall 111 of the pool 110 in the second region 111-2. The first wall posts 121-1-2 of the first walls 121-1 in the second region 111-2 are located within the second region 111-2.

[0132] Please see Figures 1 to 4 This application also proposes a cooling tower 100, which is manufactured using a design method for a cooling tower 100.

[0133] In this embodiment, for the cooling tower 100, the construction personnel determine the first bearing zone 210 and the second bearing zone 220 within the foundation 200 based on its bearing capacity. The bearing capacity of the foundation 200 in the first bearing zone 210 differs from that in the second bearing zone 220, and the bearing capacity of the foundation 200 in the first bearing zone 210 is greater than that in the second bearing zone 220. By casting foundation piles 230 in the second bearing zone 220 and inserting at least a portion of the piles 230 into the foundation 200 of the second bearing zone 220, the bearing capacity of the foundation 200 in the second bearing zone 220 can be increased, thereby reducing the difference between the bearing capacity of the foundation 200 in the first bearing zone 210 and the bearing capacity of the foundation 200 in the second bearing zone 220. When a water tank 110 is formed on the surface of the foundation 200, the piles 230 inserted into the foundation 200 in the second bearing area 220 can support the water tank 110 to ensure that the settlement value of the water tank 110 in the second bearing area 220 is within the target range; reduce the difference between the settlement value of the water tank 110 in the first bearing area 210 and the settlement value of the water tank 110 in the second bearing area 220; thereby reducing the risk that the final cooling tower 100 will tilt due to the large difference in bearing capacity between the water tank 110 in the first bearing area 210 and the second bearing area 220.

[0134] In the above process, since the first bearing zone 210, which has a stronger bearing capacity, does not have foundation piles 230, the foundation piles 230 are only poured in the second bearing zone 220, which has a weaker bearing capacity. This reduces the number of foundation piles 230, ensuring that foundation piles 230 are installed in the areas of the foundation 200 where the bearing capacity needs to be strengthened, thus reducing the waste rate of foundation piles 230. In summary, the cooling tower 100 in this embodiment, by pouring foundation piles 230 only in the second bearing zone 220 of the foundation 200, which has a weaker bearing capacity, can reduce the total number of foundation piles 230, reduce the workload of pouring foundation piles 230, and reduce the waste rate of foundation piles 230.

[0135] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0136] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
