PVC/PVDF coated canvas liner: as the inner container of the water tank, it directly contacts and stores water. This material has good flexibility and waterproof properties, and has good resistance to ultraviolet rays, which helps to extend the service life.

Advantages

Easy to install: Due to its modular design, the corrugated steel water tank can be assembled in a short time and is suitable for rapid deployment scenarios.

Convenient transportation: Compared with traditional chushui or metal fixed water tanks, this type of water tank is light in weight, small in size, and easy to handle and transport.

Cost-effective: The overall cost is relatively low, especially for projects that need to be used for a short period of time, which can effectively reduce the initial investment cost.

Strong adaptability: It can be adjusted according to different terrain conditions and is suitable for use in a variety of environments.

Corrugated Steel Water Tank Structure

The galvanized canvas water tank is an innovative modular water storage facility. Its core structure consists of two key components: a galvanized sheet support system and a waterproof canvas lining. This carefully designed combination takes full advantage of the performance of both materials to create a water storage solution that is both sturdy and practical.

Galvanized sheet support: Made of national standard hot-dip galvanized steel sheet with a thickness of 1.0-2.0mm, it is pressed into a wavy corrugated plate by heavy machinery. This corrugated design is not just for beauty, it can effectively increase the structural strength of the steel plate and increase its compressive capacity by more than 30%. The galvanizing treatment provides all-round anti-rust protection for the steel plate, and even zinc layer protection can be obtained evenly even in recesses, corners and hidden places. Each corrugated plate is fixed by double rows of screws to form a stable circular frame. This modular design makes installation and removal simple and efficient.

Canvas lining: High-strength PVC cut cloth is selected as the waterproof layer. This material has excellent physical and chemical properties. The production process of knife-cut cloth is special. The PVC slurry is evenly coated on the polyester fiber mesh base cloth through the scraper coating technology to form a waterproof layer with a thickness of 0.45-0.9mm. Its gram weight is 500-900 grams/square meter, which gives the material excellent tear resistance (warp strength ≥2100N/5CM, weft strength ≥1600N/5CM). This canvas not only has excellent waterproof performance (water pressure resistance value ≥2000MM water column), but also has cold resistance (can withstand low temperature of -20℃), mildew resistance (mildew resistance test reaches level 1), aging resistance and UV resistance.

The circular design of the galvanized canvas reservoir is the key to its success. When the water body is full, the water pressure will act evenly on all directions of the circular pool wall to form hoop stress. This evenly distributed force puts the bracket system in the most stable mechanical state. Compared with square or other polygonal shapes, the circular design can more effectively resist water pressure and avoid deformation or damage caused by local stress concentration. At the same time, the circular structure also creates an internal space without dead corners, which is convenient for cleaning and drainage. The sediment at the bottom of the pool can be efficiently removed through the drainage port at the bottom. This scientific structural design makes the galvanized canvas water storage tank an ideal water storage solution that takes into account both strength and practicality.

Corrugated steel water tanks have shown significant advantages in many aspects due to their unique design and material selection, making them a modern alternative to traditional water storage facilities.

Significant economic benefits

• Initial investment cost: Compared with traditional brick-concrete or concrete water tanks, the material cost and installation cost of corrugated steel water tanks are greatly reduced. Users do not need to bear the high cost of civil engineering and also save the complicated construction process. According to actual case comparisons, for water tanks of the same volume, the cost of the galvanized canvas solution is only one-third to one-half of that of traditional concrete water tanks.

• Installation efficiency: This water tank adopts a modular assembly method, and does not require a professional construction team. Ordinary workers can complete the installation after simple guidance.

Corrugated steel water tanks have been widely used in many fields due to their unique advantages. Their flexible design and powerful functions enable them to meet the diverse needs of different industries.

Intensive aquaculture revolution

The traditional aquaculture model relies on natural ponds or cement pools, which have problems such as large land occupation, serious waste of water resources, and difficult pollution control. Galvanized canvas water tanks provide innovative solutions for modern intensive aquaculture:

• High-density farming: Corrugated steel fish ponds combined with efficient aeration systems and circulating water treatment technology can greatly increase the farming density per unit area. Data show that compared with traditional earth pond farming, the farming density of canvas ponds can be increased by 3-5 times, such as grass carp farming density of 50-80 tails/cubic meter, and white shrimp farming density of 300-500 tails/cubic meter. This high-density farming model significantly improves land utilization efficiency, especially suitable for areas with tight land resources.

• Environmental control advantages: The inner wall of the canvas pool is smooth, and the no-dead-angle design effectively prevents the growth of harmful bacteria and parasites. Farmers can precisely control key parameters such as water temperature, pH value, dissolved oxygen content, etc. to create the best growth environment. Compared with traditional fish ponds, the disease incidence rate of canvas pond farming is reduced by about 30%, and the survival rate of fish and shrimp is increased by 15%-20%.

• Multi-species adaptability: Corrugated steel fish ponds are suitable for aquaculture of various aquatic products, including fish (such as sea bass, mandarin fish, yellow catfish, koi), shrimp (white shrimp, Macrobrachium rosenbergii), special aquatic products (crabs, leeches, turtles), etc.. Different types of aquatic products can adopt different management modes in independent pools according to their ecological habits, realizing a scientific model of multi-breeding in one plant and zoned breeding.

• Circulating water system integration: Corrugated steel water tanks are particularly suitable for use with recirculating aquaculture systems (RAS). Through sand tank filtration equipment, the entire pool water can be filtered and treated within a few hours to keep the water quality stable and clean. This closed circulation system saves more than 70% of water compared to traditional water aquaculture, while reducing wastewater discharge, meeting the environmental protection requirements of modern aquaculture.

Agricultural irrigation optimization solution

The biggest challenge facing the agricultural irrigation field is the uneven spatial and temporal distribution of water resources, especially in hilly and mountainous areas and seasonal drought areas. Corrugated steel agricultural reservoirs provide an efficient solution for agricultural water management:

• Efficient irrigation in mountain orchards: In mountain orchards that lack a stable water source, corrugated agricultural reservoirs can be built according to the terrain to collect rainy season precipitation and use it for irrigation in the dry season. A standard pool with a diameter of 10 meters and a height of 1.8 meters can reach a volume of 140 cubic meters, which is enough to support the irrigation needs of 20-30 acres of orchards for a week. The pool is built high in the orchard to form a gravity self-flow irrigation system, which can achieve efficient irrigation without additional power and greatly reduce energy costs.

• Precision irrigation support: Corrugated steel pools combined with modern irrigation technology can support precision irrigation methods such as drip irrigation and micro-spraying. Compared with traditional flood irrigation, this precision irrigation method can save 30%-50% of water while increasing crop yield and quality. For high-value economic crops such as tea, flowers, and fruits, this water-saving and efficiency-enhancing advantage is particularly obvious.

• Multifunctional application: In addition to irrigation, agricultural corrugated steel water tanks can also be used for storage of liquid fertilizers for agricultural materials, water sources for spraying systems, and drinking water reserves for livestock and poultry. In farms, they can be used for livestock drinking water systems; in greenhouses, they can also be used as cooling water curtain water sources; in ecological farms, they can also be used as a component of the fish-vegetable symbiotic system. This versatility significantly improves the utilization efficiency of infrastructure.

Temporary water supply and special application solutions

The rapid deployment capability and flexible configuration characteristics of corrugated steel water tanks make them play an irreplaceable role in temporary water supply and special application scenarios:

• Temporary water supply for engineering construction: In construction sites far away from the municipal water supply network, corrugated steel water tanks can be used as an efficient and economical temporary water storage solution. Used for construction water needs such as concrete mixing, dust suppression spraying, and equipment cooling. Compared with transporting bottled water or laying temporary pipelines, this solution can reduce water supply costs by more than 60%. After the project is completed, it can be quickly disassembled and moved to the next construction site to achieve resource recycling.

• Emergency water supply guarantee for disaster relief: In emergency situations such as natural disasters, corrugated steel water tanks can be quickly deployed to provide safe drinking water reserves for disaster areas. Its modular design facilitates transportation and can be transported to the site under limited road conditions and assembled in a short time. The pool can be connected to water purification equipment to form a complete emergency water supply system. After flood disasters, it can also be used for temporary breeding of fish and other aquatic products affected and transferred to reduce disaster losses.

• Innovative application of leisure and entertainment: Corrugated steel water tanks also have unique application value in the field of leisure and entertainment. Temporary swimming pools can be quickly built to meet the needs of summer heat relief; they can also be used as children's paddling pools in water parks; they can also be used as fishing ponds in fishing grounds to provide fishing enthusiasts with a convenient and comfortable fishing experience. Compared with traditional fixed swimming pools, canvas pools have the advantages of low cost, strong seasonality, and winter storage, which are particularly suitable for seasonal business places such as resorts and homestays.

• Ecological protection and landscape construction: In the field of ecological protection, corrugated steel can be used to build drinking water points for wild animals, especially in arid areas; in landscape design, it can be used as a temporary waterscape element in places that need to be quickly landscaped, such as garden exhibitions and real estate demonstration areas. Its environmentally friendly materials and recyclable characteristics also conform to the concept of modern ecological construction.
