Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a waterproof concrete structure for the upper part of a cooling tower. Background Technology

[0002] Traditional cooling tower superstructures are mostly constructed using on-site continuous concrete pouring. While this method can meet structural strength requirements to some extent, it has several problems. On the one hand, during continuous pouring, uneven heat dissipation in the concrete can easily lead to cracking, which becomes a channel for moisture penetration, reducing the structure's impermeability. On the other hand, on-site pouring has a long construction period and is greatly affected by external factors such as weather and temperature, making it difficult to ensure consistent construction quality.

[0003] Furthermore, with the continuous advancement of industrial technology and increasingly stringent environmental protection requirements, higher demands are being placed on the seepage prevention performance of cooling towers. Traditional seepage prevention measures, such as single coatings or roll materials, often fail to meet the long-term, high-efficiency seepage prevention needs, especially under extreme climatic conditions, where the seepage prevention effect is significantly reduced. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof concrete structure for the upper part of a cooling tower to improve the anti-seepage performance of the cooling tower.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a waterproof concrete structure for the upper part of a cooling tower, the waterproof concrete structure for the upper part of the cooling tower comprising:

[0006] A plurality of annular precast concrete blocks, wherein the cross-section of the annular precast concrete blocks is arched upward in the middle, and the annular precast concrete blocks are stacked on top of each other to form the upper part of the cooling tower; a V-shaped anti-seepage layer is provided between adjacent annular precast concrete blocks.

[0007] In one embodiment, an anti-corrosion layer is further included, which is disposed on the outer surface of the annular precast concrete block.

[0008] In one embodiment, an inner impermeable layer is further included, which is disposed on the inner surface of the annular precast concrete block.

[0009] In one embodiment, the arched shape of the annular precast concrete block is designed to be parabolic or circular.

[0010] In one embodiment, the inner impermeable layer is made of a waterproof material.

[0011] In one embodiment, the annular precast concrete block is provided with reinforcing ribs inside.

[0012] The above-described technical solutions in the embodiments of this utility model have at least the following technical effects or advantages:

[0013] The anti-seepage concrete structure for the upper part of the cooling tower provided in this embodiment of the utility model utilizes annular precast concrete blocks to construct the upper structure of the cooling tower, and sets a V-shaped anti-seepage layer between adjacent precast blocks, effectively enhancing the anti-seepage capacity of the concrete structure. This design not only reduces uneven heat dissipation and cracking problems caused by continuous pouring, but also provides double anti-seepage protection for the cooling tower through the addition of the V-shaped anti-seepage layer, significantly improving the overall anti-seepage performance. The annular precast concrete blocks can be standardized in the factory, ensuring the consistency of quality of each precast block. During on-site construction, these precast blocks only need to be stacked according to the design, greatly simplifying the construction process, shortening the construction cycle, and reducing the large amount of formwork and labor costs required for on-site pouring, thereby improving construction efficiency and project quality. The upward arched design of the annular precast concrete blocks not only helps to enhance the load-bearing capacity of individual precast blocks, but also forms a more stable overall structure after stacking, effectively resisting the stress caused by external loads and temperature changes, and extending the service life of the cooling tower.

[0014] In summary, the anti-seepage concrete structure of the upper part of the cooling tower of this utility model effectively improves the anti-seepage performance, construction efficiency and quality of the cooling tower, and enhances the structural stability. Attached Figure Description

[0024] Please see Figures 1 to 2 This application provides a waterproof concrete structure for the upper part of a cooling tower, including several annular precast concrete blocks 1. The cross-section of the annular precast concrete blocks 1 is an arched shape with the middle part facing upward. The annular precast concrete blocks 1 are stacked on top of each other to form the upper part of the cooling tower. A V-shaped waterproof layer 2 is provided between adjacent annular precast concrete blocks 1.

[0025] In this embodiment, the upper part of the cooling tower is made of annular precast concrete blocks 1. Each annular precast concrete block 1 is cast separately and then assembled. This greatly reduces the phenomenon of reduced airtightness of concrete caused by cracking and other defects due to uneven heat dissipation during continuous casting, thus improving the anti-seepage function of the cooling tower. Furthermore, a V-shaped anti-seepage layer 2 is set between adjacent annular precast concrete blocks 1, providing double anti-seepage protection for the cooling tower and significantly improving the overall anti-seepage performance.

[0026] In one embodiment, an anti-corrosion layer 3 (specifically made of materials such as epoxy resin) is also included, which is disposed on the outer surface of the annular precast concrete block 1. The addition of the anti-corrosion layer 3 can effectively isolate the precast concrete block from external environmental corrosion. Especially for cooling towers exposed to corrosive gases, liquids, or harsh weather conditions, the anti-corrosion layer 3 can greatly extend the service life of the precast concrete block and reduce structural damage and maintenance costs caused by corrosion.

[0027] In one embodiment, an inner waterproof layer 4 is further included, which is disposed on the inner surface of the annular precast concrete block 1. The inner waterproof layer 4 further enhances the seepage prevention capability inside the cooling tower, especially when cooling water directly contacts the inner surface of the precast block. The inner waterproof layer 4 effectively prevents water penetration, protects the concrete structure from erosion, and also helps maintain the stability and efficiency of the internal environment of the cooling tower. Optionally, the inner waterproof layer 4 is made of a waterproof material, such as asphalt waterproof membrane, polymer-modified asphalt waterproof membrane, or synthetic polymer waterproof membrane.

[0028] In one embodiment, the arched shape of the annular precast concrete block 1 is designed as parabolic or circular arc. The parabolic or circular arc arched design can more effectively distribute and bear the upper load, improving the load-bearing capacity and structural stability of the precast block. At the same time, this design also facilitates close stacking between precast blocks, reducing gaps and thus enhancing the overall impermeability.

[0029] In one embodiment, the annular precast concrete block 1 is provided with reinforcing ribs inside. The reinforcing ribs can significantly enhance the strength and load-bearing capacity of the annular precast concrete block 1. Especially when the precast block is subjected to large loads or vibrations, the reinforcing ribs can play a good supporting and stress-dispersing role, improve the crack resistance and overall stability of the precast block, and thus ensure the safe operation of the cooling tower.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
