Description

Technical Field

[0001] This utility model relates to a hyperbolic inclined support foundation for a cooling tower with integrated pile and column, belonging to the field of special structure technology for power systems. Background Technology

[0002] The inclined supports, serving as the load-bearing structural members of the hyperbolic cooling tower, are typically constructed of reinforced concrete and come in various shapes, including A-frame, V-shape, X-shape, and I-shape. Below the inclined supports is a ring slab foundation, and below that, various types of pile foundations. The inclined supports bear the vertical and horizontal forces from the upper part of the cooling tower, transmitting them downwards to the ring slab foundation, and ultimately, the pile foundations bear all the vertical and horizontal forces.

[0003] Inclined pile foundations have been widely used in bridge and shipping fields, and the technical system is relatively complete. However, they have not yet been used in the construction of hyperbolic cooling towers. Utility Model Content

[0004] The technical problem to be solved by this utility model is that, since there is no inclined pile foundation for hyperbolic cooling towers in the existing technology, this invention provides an integrated pile and column inclined support foundation for hyperbolic cooling towers.

[0005] To solve the above problems, this utility model is achieved through the following technical solution: A hyperbolic cooling tower inclined support with integrated pile and column includes a foundation platform, and an integrated pile and column inclined support is provided below the foundation platform. The bottom of the integrated pile and column inclined support is connected to a ring plate foundation. A pile foundation is provided at the bottom of the ring plate foundation. The pile foundation includes at least one inclined pile foundation and at least one vertical pile foundation. The integrated pile-column inclined support includes an I-shaped column located above the ring slab foundation and an inclined pile located below the ring slab foundation, with the I-shaped column and the inclined pile being coaxial.

[0006] The I-shaped column has a circular cross-section.

[0007] The centerline of the ring slab foundation serves as the dividing line. Inclined pile foundations are used in the area above and outside the centerline of the ring slab foundation, while vertical pile foundations are used in the area inside the centerline of the ring slab foundation. Furthermore, the inclination angle of all inclined pile foundations below the ring slab foundation should be consistent with the inclination angle of the integrated pile and column inclined support.

[0008] The number of rows and columns of inclined pile foundations and vertical pile foundations should be evenly distributed.

[0009] Inclined pile foundations use steel pipe concrete piles, PHC pipe piles, or reinforced concrete piles.

[0010] Vertical pile foundations use steel pipe concrete piles, PHC pipe piles, or reinforced concrete piles.

[0011] The pile heads of inclined pile foundations and vertical pile foundations should be anchored into the ring slab foundation by at least 100mm. The inclined piles of the integrated pile-column inclined support below ground level should be completely enclosed in the ring slab foundation.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. It improves the load-bearing capacity of the cooling tower foundation, makes full use of the inclined pile foundation to mainly bear the inclined force transmitted from the inclined support, optimizes the structural form, simplifies the force transmission path, and enhances the load-bearing capacity.

[0013] 2. It increases the stability of the cooling tower foundation. The tree-like structure formed by the inclined pile foundation and the vertical pile foundation enhances the overall stability and can effectively resist various external forces.

[0014] 3. The cooling tower foundation has a uniform stress distribution. The tree-like structure formed by the inclined pile foundation and the vertical pile foundation ensures that the stress is evenly distributed and avoids excessive local stress.

[0015] Cooling tower foundations are highly adaptable. The tree-like structure formed by inclined pile foundations and vertical pile foundations enhances pile-soil interaction, making them suitable for a variety of different geological conditions and construction environments.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, a hyperbolic cooling tower inclined support foundation with integrated pile and column includes a foundation platform 1. An integrated pile and column inclined support 2 is provided below the foundation platform 1. The bottom of the integrated pile and column inclined support 2 is connected to a ring plate foundation 3. A pile foundation 4 is provided at the bottom of the ring plate foundation 3. The pile foundation 4 includes at least one inclined pile foundation 41 and at least one vertical pile foundation 42, thereby forming a tree-branch type stable load-bearing structure.

[0021] The integrated pile-column inclined support 2 includes an I-shaped column 21 located above the ring foundation 3 and an inclined pile 22 located below the ring foundation 3. Here, the I-shaped column 21 is the inclined support of the hyperbolic cooling tower. During construction, the I-shaped column 21 and the inclined pile 22 are coaxial.

[0022] The inclination angle 6 of the integrated pile-column inclined support 2 is the inclination angle of the I-column 21. The angle between the I-column 21 and the vertical direction is determined by the diameter and height of the cooling tower.

[0023] Even better, I-shaped column 21 has a circular cross-section.

[0024] Furthermore, taking the center line 5 of the ring foundation as the dividing line, inclined pile foundations 41 are used in the area above and outside the center line 5 of the ring foundation, while vertical pile foundations 42 are used in the area inside the center line 5 of the ring foundation. The inclination angle of all inclined pile foundations 41 below the ring foundation 3 should be consistent with the inclination angle 6 of the integrated pile-column inclined support 2.

[0025] The number of rows of all piles 4 below the ring foundation 3 along the radial direction of the ring foundation 3 and the number of columns perpendicular to the radial direction of the ring foundation 3 should be evenly distributed.

[0026] Inclined pile foundations 41 can be made of various materials such as steel pipe concrete piles, PHC pipe piles or reinforced concrete piles, depending on the geological conditions and construction site conditions.

[0027] The material of the vertical pile foundation 42 can be different from that of the inclined pile foundation 41. It can be a variety of materials such as steel pipe concrete piles, PHC pipe piles or reinforced concrete piles, depending on the geological conditions and construction site conditions.

[0028] The construction method of this utility model is as follows: The diameter and height of the cooling tower, determined by the process engineer, are used to calculate and determine the inclination angle 6 of the I-shaped column 21. The centerline 5 of the ring foundation is determined based on the intersection of the center point of the I-shaped column 21 and the top surface of the ring foundation 3. Inclined pile foundations 41 are used on and outside the centerline 5 of the ring foundation, while vertical pile foundations 42 are used inside the centerline 5 of the ring foundation.

[0029] The diameter, length, and number of inclined pile foundations 41 and vertical pile foundations 42 are determined by calculation. The number of rows and columns of inclined pile foundations 41 and vertical pile foundations 42 should be evenly distributed.

[0030] First, construct the inclined piles 22 below ground level of the integrated pile-column inclined support 2. Using the inclined piles 22 as the center, construct the other inclined pile foundations 41 outwards in sequence, and finally construct the vertical pile foundations 42 in sequence. The inclination angle of the inclined pile foundations 41 must be consistent with the inclination angle 6 of the integrated pile-column inclined support 2. During construction, the coordinate positioning of the center point of the inclined pile foundations 41 must be accurate. Special attention should be paid to the inclination angle 6 of the inclined pile foundations 41 during hoisting and driving, and it should be checked and corrected frequently to ensure it meets design requirements.

[0031] The pile heads of inclined pile foundations 41 and vertical pile foundations 42 should be anchored into the ring slab foundation 3 by at least 100mm. The inclined piles 22 of the integrated pile-column inclined support below ground level should be completely enclosed within the ring slab foundation 3, and reinforcing bars should be pre-installed. Special attention should be paid to the joint position of the inclined piles 22 and I-shaped columns 21 of the integrated pile-column inclined support to ensure construction quality.

[0032] After the ring foundation 3 is completed, the I-shaped column 21 of the integrated pile and column inclined support above the ground is constructed. During the construction process, it is ensured that the inclination angle 6 of the integrated pile and column inclined support 2 is without deviation, and the positioning accuracy, the quality of the steel bar connection and the compactness of the concrete pouring are controlled.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
