Description

Aquaculture water tank.

The present invention relates to a storage tank in which a breeding tank or living water of a farm can be stored. One or more panels having a C-shaped or A-shaped cross-sectional structure are connected to form a tank outer wall, and thus easy to install and install without foundation work. And it relates to a prefabricated reservoir tank for excellent durability.

A reservoir is a tank for storing water, drugs, and other fluids such as wastewater at power plants, large and medium buildings, and wastewater end treatment plants, farms, and swimming pools. Reservoir tanks can be largely divided into underground tanks and elevated tanks, and can be classified into stainless panel tanks, SMC tanks, FRP tanks, and concrete tanks depending on the material.

 The water tank is manufactured and used in various materials and shapes according to the type of fluid stored, the amount of storage, and the use.However, the coating film has good compressive strength, and has excellent elasticity, acid resistance, alkali resistance, chemical resistance, and ozone resistance. The tank structure should be easy to check and maintain, have sufficient strength and be formed to prevent water pollution.

Fish and shrimp swimming species that are actively active in the normal water should be protected by escapes by establishing a boundary with a moth or net to prevent aquaculture from running away, and start with the installation of devices to maintain the natural environment. It became. These types of farming include pond farming, stream farming, cage farming, and circulation filtration farming methods.

In general, concrete reservoirs are widely used as storage tanks for breeding ponds or living water. Concrete reservoirs are formed by forming walls of concrete and welding a plurality of stainless panels therein, and each panel is welded and supported by stainless struts arranged vertically and horizontally.

Such concrete reservoirs may be installed in the outer space, but are often constructed in a buried form underground. In particular, some of the concrete reservoir to be embedded is installed to be buried to open one side, there is also a landfill is installed so as to excavate the fillet and all the slopes are closed.

However, concrete structures have a certain degree of water tightness, but cracks are generated inside and outside the structure due to micro cracks and irregularities occurring during curing, and cracks caused by external forces transmitted from the outside. Occurs. This leak deepens the cracks and impairs the functionality of the concrete structure in the future. In addition, the method of lining the stainless panel is typically made by welding, which may cause problems such as perforation, bending, and twisting.

The breeding tank or storage tank of the farm is to be manufactured by welding the tank wall integrally formed on the bottom of the tank at the site to install, or by pouring the bottom and walls of the tank with concrete. Therefore, the time and cost of the installation work is proportional to the size of the tank, it is difficult to dismantle and reinstall when the position of the tank is moved or reinstalled.

STS (Stainless) lining, PE (Polyethylene) lining, etc. can be damaged in concrete structure by planting anchors in the structure, and it can damage the concrete structure. In particular, the factors that may shorten the life of the structure due to corrosion of reinforced steel bars have been pointed out. In addition, even when waterproofing polyurea, the existing method is peeled and stained, discolored and is not suitable for application. In general, the most widely used resin for forming a coating film for imparting acid resistance and water resistance to concrete structures is epoxy resin or unsaturated polyester resin.

In particular, unsaturated polyester-based resin is used in a tank tank where acid resistance is required as FRP (Fiberglass Reinforced Plastics) resin, which is used together with glass fiber. These epoxy resins and FRP resins have been used in the waterproofing method of forming a coating film on the concrete surface in order to protect and waterproof the concrete of the storage tank is excellent acid resistance. These concrete structures have the advantages of high strength and excellent durability and long service life. However, when used without treatment such as a separate lining, the deposits penetrate into the concrete structures, causing cracks, and these cracks lead to leakage of the deposits. .

Stainless steel tank is installed in high-use buildings such as residential apartments and business buildings, and used as a high or low cost tank to store water. The stainless steel tank is formed by cutting a stainless steel plate having a predetermined thickness into a predetermined standard and then pressing and bending to form a unit panel, and joining each side of the unit panel by welding to form a rectangular enclosure.

Prefabricated breeding water reservoir or reservoir for aquaculture farms of the present invention is a square or rectangular tank bottom 100 of the concrete material; A plurality of outer wall panels 200 having a predetermined height are connected to the tank bottom in a horizontal direction and a vertical direction to surround the tank bottom to form a closed water storage space, and a square in which the outer wall panels of the horizontal direction and the vertical direction cross each other. The corner panel 300 may be installed at the corner.

The tank bottom 100 of the present invention is to form a watertight structure by placing concrete in a square or rectangular structure of a predetermined thickness formed of a concrete material on the ground to be prefabricated tank is installed and waterproof, anticorrosive work. It is preferable that the height of the part where the outer wall panel of the bottom of the tank bottom in which concrete is poured is erected is lower than that of the concrete tank bottom part.

The height of the bottom part of the tank is higher than the lower part of the outer wall panel touching the ground, which prevents the stored water stored in the reservoir from being pushed under the outer wall panel by receiving the water pressure according to the atmospheric pressure and the height of the stored water. . In addition, in order to reinforce the phenomenon of falling into the bottom of the outer wall panel according to the water pressure, the concrete pouring of the part where the outer wall panel is erected can be configured to have a groove having a predetermined depth lower than the side of the bottom of the tank.

In addition, in the case of low pool pools or farm pools, the existing concrete floor can be used as it is, and if there is no concrete floor, only the bottom of the tank can be poured into concrete to manufacture the water tank. Save time.

The watertight structure is to prevent water from entering or leaking outside or inside the structure when water directly comes into contact with the water tank structure, and forms a film (membrane layer) on the surface of the poured concrete structure. do.

Waterproofing, anticorrosion according to the present invention gave a waterproofing effect of the concrete is relatively inferior waterproofing by the waterproofing coating treatment on the surface of the concrete structure. The coating agent according to the present invention may include asphalt, coal tar pitch, urethane, epoxy, etc., preferably excellent tensile strength and elongation rate, excellent chemical resistance, excellent durability and fast curing time to shorten the construction period Polyurea, which can be used. The polyurea has excellent interlayer adhesion and tear, tensile strength and durability for waterproofing, and is very resistant to chemicals due to its strong chemical resistance. In addition, the coating film of the waterproof polyurea has the advantage that it is easy to manufacture and harden time in a short time.

Figure 2 shows a perspective view of the outer wall panel and the corner panel of the present invention. The outer wall panel 200 of the present invention has a structure having a U-shaped cross-sectional shape is connected by a vertical slat frame formed by bending both ends of the horizontal slat frame of a steel plate having a predetermined surface by a predetermined length by 90 degrees. The length ratio of the horizontal slat frame constituting the outer wall panel and the vertical slat frame at both ends may be a ratio of 10: 2 to 5. In an embodiment, when the horizontal slat frame is 100 cm, the length of the vertical slat frames on both sides to be bent is preferably about 20 to 50 cm.

The outer wall panel is vertically installed with the U-shaped cross section abutting the ground so that the horizontal slat surface faces the inner surface of the closed water tank of the farm, and the vertical slat frame is supported toward the water tank outward. A single outer wall panel and the vertical frame surface of the neighboring outer wall panel is in contact with each other is fixed by a fixing device (S) so that a plurality of outer wall panels are horizontally connected to be fixed and installed. As an embodiment of the fixing device was formed of a bolt and nut, but the fixing device receiving hole is formed in the side of the vertical frame of the neighboring outer wall panel so that the fixing device can be fixed through, but is not limited thereto.

An edge panel is installed at a rectangular corner where a plurality of outer wall panels connected in a vertical direction and a horizontal direction cross each other. The edge panel 300 is formed in a b-shaped cross-section structure in which a vertical slat frame is connected to one end of a horizontal slat frame having the same area by bending the center of a steel plate having a predetermined surface by 90 degrees. The length ratio of the horizontal slat frame and the vertical slat frame constituting the corner panel is preferably in a ratio of 1: 1. For example, when the horizontal slat frame is 20 to 50 cm, the length of the vertical slat frame to be bent is also 20. About 50 cm is appropriate.

The edge panel may be embedded in the vertical slat frame surface and the vertical slat frame surface of the transverse outer wall panel formed at the rectangular corners and connected to each other via a fixing device. The outer wall panel and the edge panel are connected along the edge of the tank bottom to form a tank outer wall structure having a predetermined height, and a storage space for storing breeding and farmed or drinking water and living water is formed. In addition, since the outer wall panel is coupled to each other with a slat frame and a fixing device, even without a separate steel beam support structure can withstand the water pressure due to high internal water storage.

Fixing with bolts and nuts as an embodiment of the fixing device is easy to assemble in the field can be omitted welding and lining work in conventional concrete or stainless steel tank work has the effect of reducing the work process and cost. In addition, the outer wall panel is fixed to one or more vertical frame to form a bone structure toward the outside serves as a support structure that can withstand the strong water pressure of the breeding water and living water stored in the storage space.

Thus, even in a large-sized tank, the vertical slat frame surface of the outer wall panel acts as a supporter without additionally installing a reinforcing structure or a supporting structure, thereby preventing it from being pushed out by the water pressure stored in the reservoir. In addition, in the case of a conventional circulation filtration tank and a large fish tank, it was possible to withstand the water pressure to be formed in a buried structure, but the water tank according to the present invention in the water tank of more than 5 meters in height not buried in the outer wall without installing a separate support structure The panel can withstand it.

The frame back of the “c” shaped recessed structure is formed with an outer wall layer 30 laminated with a fiber reinforced plastics (FRP) material, and the FRP is stacked with a thickness of 10 to 20 times. The frame of the indentation structure of is padded. The inner space formed by the inner wall layer and the outer wall layer may be formed of a support member 40 of each pipe shape installed in a horizontal or vertical direction and an inner layer 20 filled with urethane, and the outer wall layer and the inner wall layer side surfaces It is appropriate to coat the film with the coating agent.

In the case of the tank structure that is not concrete, the outer wall constituting the outside of the water tank must have a reinforcement or internal reinforcement such as steel frame on the outside when the height is more than 3m or longer. Function, the thickness of the reinforced outer panel has a thickness of 5 to 20 cm, so that the thickness of the vertical slat frame in contact with the vertical slat frame of the outer panel is 10 to 40 cm wide and 20 to 50 cm Its length provides its own strong support structure, which prevents the connected external panel from being pushed out by hydraulic pressure.

In the same way as the outer wall panel, the inner wall layer is formed on the side of the edge panel in contact with the storage space by converging the vertical and horizontal frames, and the outer wall layer is formed on the side of the frame to be embedded, and the inner space of the outer wall layer and the inner wall layer An inner layer may be formed. In addition, the coating is performed with a coating agent as in the outer panel. The thickness of the fixed corner frame also has a width of 10 to 40 cm and a length of 20 to 50 cm to provide a strong supporting structure on its own.

The urethane material according to the present invention may preferably be a conventional polyurethane foam (polyurethane foam). Urethane does not have problems such as dust generation during manufacturing, so it provides a comfortable working environment. The ordinary structure constructed of urethane panel has the effect of sound insulation, waterproof, moisture proof, etc. in addition to excellent heat insulation performance.

The support member constituting the inner layer may be installed in one or more vertical or horizontal directions in the inner space in the shape of an angular pipe formed of wood or stainless steel to enhance durability of the outer wall panel.

The alloy plated steel sheet material according to the present invention is preferably made of a ternary high corrosion resistant steel sheet (KSD3030), which typically includes zinc, magnesium, and aluminum. Magnesium in the plating layer of the alloy-coated steel sheet promotes the formation of dense corrosion products in a very stable state to form a film-like layer on the surface of the plating layer, so that a film may be formed on cut or damaged portions to protect against corrosion.

In addition, the high corrosion resistant steel plate (KSD3030) has corrosion resistance of 5 to 10 times higher than that of the existing galvanized steel sheet, so that the structure is almost unchanged even in the long-term installation, so it is necessary to replat the cut portion generated from the existing plated steel sheet. In addition, there is almost no problem of causing environmental pollution and maintenance is not necessary, which increases the life of the structure. Accordingly, the outer wall panel side in which the inner wall layer is formed is in contact with a storage space in which breeding water or living water is stored, and the structure is not deformed or hardly corroded even if it is in contact with moisture for a long time.
