On the other hand, prefabricated panel tanks for water are in wide demand due to their economical, scalable, and potable advantages. However, current techniques are not suitable for water tightness due to the weakness of elastomeric gaskets or seals that join the panels together. Water or chemical prefabricated panel tanks are also resistant to the poor chemical resistance of panel materials such as fiberglass, reinforced polymer, hot dipped galvanized, and stainless steel. Limited by Therefore, the present application aims to provide one or more prefabricated panel tanks that are more durable and scalable for storing or transporting water or chemical solutions firmly or reliably. Alternatively stated, the present application aims to provide a new purpose for prefabricated panel tanks.

As a first aspect, the present application discloses a prefabricated panel tank (ie, a panel tank, a panel assembled tank, or a concealed container). The prefab panel tank includes one or more sidewalls that are joined together when forming the prefab panel tank. The sidewall includes a first unit panel having a first extension at a first edge of the first unit panel, and a second unit panel having a second extension at a second edge of the second unit panel. . By coupling the first extension to the second extension, the second unit panel is then connected or attached to the first unit panel to provide a continuous surface of the sidewall. As a whole, the first unit panel and the second unit panel provide structural support for a sidewall or prefab panel tank. The first unit panel or the second unit panel may have a design that is stretchable in terms of shape and dimensions. In some embodiments, the first or second unit panel size is a size not exceeding 4 square meters, and a maximum of 20 mm, such as 2 mm or less (e.g., 1.2 mm, 1 mm, 0.5 mm). , Preferably 16 mm, preferably 10 mm, preferably 6 mm, preferably 4 mm (millimeters).

The first unit panel and the second unit panel are optionally made of impermeable, corrosion resistant or resistant, structurally strong materials. For example, the unit panels or sidewalls of a prefabricated panel tank are stainless steel (SUS 304 or SUS 316), mild steel (such as hot dipped galvanized (HDG) or epoxy coated). , Sheets of hot pressed metals or metal alloys such as copper, bronze, brass, or galvanized steel; Plastics such as polyethylene or polypropylene; And glass reinforced plastics including fiberglass reinforced polymers (FRP) (FRP/SUS or HDG/SUS), or rubbers, EPDM, and a mixture of rubber and plastics; GRP). Unit panels made of plastics or composites are particularly suitable for chemical equipment such as tanks or vessels. For example, chemical equipment with sizes ranging from less than 1 meter to 20 meters is fabricated by FRP unit panels. Additionally, the first unit panel and/or the second unit panel may be used in any coating for additional functions, e.g., for water sealing (fluoropolymer, epoxy, phenolic, Impermeable coatings such as phosphate, PTFE, and FEP; Water-repellent coatings (such as silicone, polyurethane, and zinc) for waterproofing; And corrosion-resistant or chemically resistant coatings (such as PE, PP, PVDF, and ECTFE) to prevent corrosion. In particular, a gel coating is applied onto the FRP unit panel to prevent any damage caused by ultraviolet (UV) rays and, on the one hand, to make a smooth surface.

The first unit panel and the second unit panel have substantially similar or identical shapes (e.g., square, rectangular, hexagonal), profiles, sizes, so that the first and second panels can be mass produced and standardized. Structures, materials, and/or mechanical strength. Additionally, the surfaces or contours of the first unit panel, the second unit panel, the sidewall, or a combination of any of these (segments, panels, walls) may be curved (e.g., 3D geometric shapes or 2D geometric shape) or can be straight. For example, the first unit panel and the second unit panel are aligned at an angle substantially greater than 90°, 120°, 150° (eg, about 180° to become a flat sidewall).

The first unit panel and the second unit panel are either detachably or permanently merged, fixed, or fastened together in either one. In particular, they are in the first extension and in the second extension without any intermediate materials, for example in the absence of any gasket which is a mechanical seal by means of at least one fastener on the first and second extensions. , And/or by the first extension and the second extension, are incorporated continuously, directly, or immediately in direct surface contact. In other words, the extensions or flanges of the first and second unit panels directly contact each other without any intermediate material, so that the extensions or flanges can be tightened together strongly. Therefore, the first unit panel and the second unit panel have exposed lines of division, known as seam joints.

The first extension portion and the second extension portion may adopt any shape that provides structural support for the first unit panel and the second panel, respectively. In particular, the first extension and the second extension are rigidly and non-stretchable by directly touching each other without any foreign components between the contact surfaces to form sidewalls in a rigid form. To be merged.

In some implementations, the first extension has one or more first flanges (or any other first outer or inner ridge or rim for attachment) at the edges of the first unit panel. The flange is for the strength as a flange of an iron beam, I-beam, or T-beam, or as a flange on the end of a pipe, steam cylinder, etc., for attachment to another object. , Or the exterior of a first unit panel, a second unit panel, or another panel as an extra rim or lip, providing structural support for the flange of a rail car or tram wheel. Or it is an example of a first extension part or a second extension part which is an inner ridge. The first flange is folded from the inner side of the first unit panel or prefab panel tank to the outer side. Similarly, the second extension has one or more second flanges (or any other second outer or inner ridge or rim for attachment) at the edges of the second unit panel. The second flange also folds from the inner side of the second unit panel or prefab panel tank to the outer side. As discussed above, the first flange and the second flange are rigidly and non-stretchable by touching each other directly without any extraneous components (such as gaskets) between their contact surfaces.

In some implementations, the first extension comprises a first margin of the first unit panel at its edges; The second extension portion includes a second margin portion of the second unit panel at its edges. The first margin portion and the second margin portion are directly fastened (eg, laminated) together to make the first unit panel and the second unit panel as a unitary piece, thereby forming a sidewall of the prefabricated panel tank. In particular, the first margin portion and the second margin portion have substantially similar or identical materials and/or thicknesses, respectively, so that the first margin portion and the second margin portion can be produced together with the first unit panel and the second unit panel, respectively. have. The first margin portion or the second margin portion may also be known as a flange.

The prefabricated panel tank is optionally a sealant, a plaster, a paste, an adhesive applied from the seam on the inner sides of the first unit panel and the second unit panel of the prefabricated panel tank. adhesive), or any solidified plastic material. In particular, the sealing agent is made of the same material as the first unit panel and the second unit panel, that is, stainless welding on the SUS panel, PP welding on homogeneous PP panels. A sealant is applied to prevent any leakage of liquid in the assembled panel tank from the shim. The sealant may be formed by any suitable method depending on the specific material of the sealant. For example, thermoplastic welding is employed when the sealant comprises one or more thermoplastic materials.

The first unit panel is optionally structurally extending between first extensions (such as first flanges) at the first edges of the first unit panel to withstand the pressure and weight of the fluid inside the prefabricated panel tank. Includes a panel. The structural panel can include any component that has high strength and good durability under pressure (eg, water pressure) and various environmental conditions (such as temperature, ultraviolet (UV) radiation, corrosion, wind, and rain). Additionally, the structural panel may also have reliefs (such as cross embossment at the center of the structural panel) to further withstand pressure. The structural panel can have various shapes and sizes, such as a square shape with an edge of about 1.2 meters (or about 4.0 feet) or 1.0 meter in length.

The prefabricated panel tank is optionally incorporated, attached, fixed, bonded, or fixed onto the inner side or sidewall of the first unit panel in order to prevent corrosion and leakage of fluid inside the prefabricated panel tank. It includes the above linings. The lining may have dimensions large enough to cover the interior area of the prefabricated panel tank. In addition, the lining may include a plurality of lining sheets. The lining sheets may have the same or various dimensions to cover the first unit panel or the second unit panel. For example, one single lining sheet is used to cover the first unit panel. Alternatively, multiple lining sheets are joined together to cover the second unit panel. Additionally, the lining is optionally connected to the sealant at the shim to further reinforce the sealant. In some embodiments, the lining is preferably 0.5 millimeters (mm), such as 2 to 4 mm (i.e., 2 to 4 millimeters), or preferably 1 to 5 mm (i.e., 1 to 5 millimeters). To 6 millimeters (mm). The lining or one or more of the linings is extendable and/or stretchable. Because of this, one or more of the linings can retain water inside the prefab panel tank even if the unit panels of the prefab panel tank are destroyed or broken. The inherent ability to hold liquid content (e.g., water or harmful chemical solutions) is beneficial, desirable, and desirable to maintain the integrity of the prefab panel tank even if the prefab panel tank experiences earthquakes, collisions, and/or vibrations. , And/or great.

The lining may comprise a thermoplastic material, a thermoset material, or both. Thermoplastic materials include thermoplastics and thermoplastic elastomers. Thermoplastics include PerFluoroAlkoxy (PFA), polyfluoroethylene (PolyFluoroEth), (low density PE (LDPE), cross link PE (XLPE)), high density PE (High Density PE); HDPE), and Polyethylene (PE), such as Ultra High Molecular Weight Polyethylene (UHMWPE), Polypropylene (PP), Polytetrafluoro Ethylene (PolyTetraFluoroEthylene; PTFE), ethylenechlorotrifluoroethylene (EthyleneChloroTrifFluoroEthylene), polyvinylidenefluoride (PVDF), fluorinated ethylene propylene (FEP), and perfluoroalkoxy alkanes (Perfluoroalkoxy) Alkanes; PFA). Thermosetting materials are ethylene vinyl alcohol (EthyleneVinylalcOHol; EVOH), polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), polymethylmethacrylate (PolyMethylMethAcrylate; PMMA), and acrylic. Nitrile Butadiene Styrene (ABS). Therefore, the lining is a hybrid joining method when the first unit panel is made of metals or metal alloys (such as stainless steel sheet), or plastics when the first unit panel is made of plastics or compositions. It is bound or fixed to the inner side of the side wall by coalescence. In particular, hybrid coalescence includes adhesive and solvent bonding (such as hot-metal adhesive bonding), as well as welding (such as thermal welding). The hybrid coalescence method is optionally done with suitable mechanical bonding (such as gaskets) or a combination of coalescence methods (such as clinching or press joining). The adhesive strength of the lining to the first unit panel is optionally inspected or tested by a peel test and/or a shear test with multiple force-extension courses.

The lining is optionally preformed (e.g., molded, adhered, or cast) onto the inner side comprising a first extension (such as flanges) of the first unit panel. do. The pre-forming process can be done by any suitable method depending on the nature of the prefabricated panel tank. For example, a prefabricated panel tank is made of metals (such as stainless steel), and the preforming process is done by mechanical fastening, adhesive bonding, welding, molding, or any combination of the above techniques.

Mechanical fastening methods include clamping components or fasteners (such as nuts, bolts, screws, or rivets) or (snap-fit or press-fit). Integrated design elements (such as press-fit) are often used. Additionally, mechanical fastening may also require mechanical actions such as drilling holes or making screw threads. The mechanical fastening method has several advantages such as simplicity, reliability, and ease of testing and repair.

The adhesive bonding method applies adhesives (such as polymeric adhesive) between the lining and the first unit panel. The adhesives create chemical and/or physical reactions to form intermolecular forces at the interface of the lining and the first unit panel (polyester, fiberglass, felt, geotextile). , And a fabric backed liner (such as a FBL) lining and the first unit panel are bonded together. The adhesive bonding method homogeneously distributes internal stresses across both the lining and the first unit panel, especially when incorporating an intermediate layer (e.g., a fabric material) between the lining and the first unit panel. It has a major advantage.

The welding method is shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), gas metal arc welding when the lining and unit panel are made of metal materials. welding (GMAW), submerged arc welding (SAW), ultrasonic welding, laser welding, friction stir welding, or friction spot welding Includes. For example, the lining material is titanium, while the panel material is stainless steel. The specific welding method is selected depending on the chemical and physical natures of the lining material and panel material. The specific welding method is selected depending on the chemical and physical natures of the lining material and panel material.

The molding method is to pre-heat the thermoplastics lining, granules, or pellets first to a soften state, and then, the softening lining directly onto the panel. It is done by applying. The molding method further includes compression moulding, injection moulding, blow moulding, rotational moulding, extrusion moulding, and thermoforming. In contrast, the pre-molding process is done by a polymer coalescence method when the unit panel is made of polymers (such as glass fiber reinforced polymer (FRP)) or polymer composites. The pre-forming process is thus done by mechanical fastening, adhesive bonding, welding, solvent bonding, or any combination of the above techniques. The mechanical fastening method and adhesive bonding method are generally similar to those described above for a prefabricated panel tank made of metals. The preforming process is applicable to FRP or metal (eg stainless steel), essentially independently of the materials from which the unit (substrate) panel is made.

Welding methods for polymers or polymeric materials include hot-gas welding, hot wedge welding, extrusion welding, hot plate welding, infrared (IR) welding, And external heating methods including laser welding, as well as internal heating methods. Internal heating methods include mechanical methods including spin welding, stir welding, vibration welding (ie, friction welding), and ultrasonic welding; And electrons including resistance welding (also known as implant welding or electrofusion welding), induction welding, dielectric welding, and microwave welding. It includes more miracle methods. Additionally, thermal spraying techniques, including electrical or chemical means (combustion flame) (such as plasma or arc) are also suitable for the welding of polymers or polymeric materials. In particular, plasma spraying or plasma coating is employed to weld polymers or thin layers of polymeric materials.

The solvent bonding method is particularly suitable for preforming the lining onto the unit panel, especially when the unit panel is made of polymers or polymeric materials. In particular, (polyvinyl chloride (PVC), acrylic (AK) and polystyrene (PS), polycarbonate (PolyCarbonate; PC), polymethyl methacrylate (PMMA), and acrylonitrile butadiene styrene (ABS) Such as) polymers or polymeric materials are amorphous. A solvent is applied at the interface of the two unit panels to plasticize the surfaces of polymers or polymeric materials.

The lining optionally includes a bonding layer on one or both surfaces of the lining. For example, the bonding layer includes a fabric supported liner (FBL) having a thin layer of any fabric material (such as felt, polyester) to provide a rough or coarse surface for the adhesives. do. For another example, the bonding layer is a thin homogeneous layer of mechanical fixtures with a plurality of anchors, surface texture, extensions, legs, studs. Includes. In particular, various fillers can be embedded within the gaps between the studs for specific purposes. When the fillers are porous materials such as aerogel, rigid polyurethane (PUR), polyisocyanurate (PIR), mineral wool, the lining is thermally insulating and fire resistant. resistance function, noise reduction function, and mechanical cushion function.The thermal insulation function allows prefab panel tanks to be used in special areas (such as high latitude countries in cold winter), or (spa). The mechanical cushioning function ensures that the lining is pushed tightly against the unit panel under the pressure of the water stored inside the prefab panel tank.In addition, the lining is in contact with the water. It can act as a matrix to firmly hold a variety of functional specific materials inside the lining, without losing functional particles when done, for example, the lining is a self-cleaning surface. Self-cleaning specific materials (such as titanium dioxide (TiO2)) can be retained in order to automatically remove any debris or sediments from them. , Superhydrophobic, superhydrophilic, or photocatalytic. The lining is to kill any microbial-organism in water (such as silver nanoparticles). ) May contain more antimicrobial specific substances.

The lining optionally includes a fore layer (or a first layer) and a base layer (or a second layer). In particular, the front layer and the base layer are co-extruded in manufacture to form a homogenous boned liner. Typically, the front layer and the base layer have a fore color and a base color, respectively. The base color is preferably distinctly different from the front color in human eyes, so that any erosion, wear, or destruction of the exposed front layer of the two layers is easy. The lower base layer of the two layers will be uncovered for visual testing. If the base color is observed on the inner side of the prefab panel tank, repair or replacement is then warranted.

Both layers are coalesced by co-extrusion, and/or the base and front layers are optionally made of the same or similar materials for a homogeneous coalescence. Additionally, the lining has a total thickness that is neither too thick (ie> 20 mm) nor too thin (ie <0.5 mm). In some embodiments, the total thickness is in the range of 1.0 to 6.0 millimeters (mm). The base layer and the front layer have a base thickness and an anterior thickness, respectively. Typically the front layer thickness accounts for no more than 50% (such as 10%) of the total thickness.

The prefabricated panel tank may further include a thermal insulation layer for reducing fluid temperature fluctuation within the prefabricated panel tank. The thermal insulation layer is made of a thermal insulation material that slows heat transfer by conduction or convection. Thermal insulation materials include fiberglass, mineral wool, cellulose, polyurethane foam, polystyrene, aerogel, pyrogel, (hemp, sheep wool, Natural fibers, such as cotton, and straw, and polyisocyanurate (PIR) foam. Mineral wool further includes glass wool, rock wool, and slag wool. Polystyrene also includes expanded polystyrene (EPS) and extruded polystyrene (XEPS). In particular, it is preferred that the thermal insulation material is hydrophobic or non-absorbing in water, such as glass fiber.

The thermal insulation layer further includes a plurality of thermal insulation sheets assembled on the outer side of the prefabricated panel tank. The outer side is exposed to the external environment and does not come into contact with the fluid inside the prefabricated panel tank. In some implementations, one or more thermal insulation sheets are attached to the outer side of the first unit panel or the second unit panel. The thermal insulation sheets are further assembled together into the thermal insulation layer while or after the first unit panel and the second unit panel are incorporated together into a prefab panel tank. Alternatively, the thermal insulation layer is fabricated as a monolithic part and is attached as a whole to the outer side of the prefabricated panel tank after the first unit panel and the second unit panel are joined together.

Alternatively, the outer side of the first unit panel, which is a thermally insulating layer, is treated or processed to substantially reflect light, heat, infrared waves, or any other types of irradiation. In particular, since stainless steel (also known as inox steel or inox) is reflective to solar and thermal irradiation, the first unit panel made of stainless steel can achieve the same or similar reflective effect without treatment. . Additionally, the reflective effect of stainless steel is further synthesized by not converting the wavelengths of incoming light. Therefore, the solar energies carried by the incoming light are transmitted directly back into space without substantially atmospheric absorption, which effectively prevents re-radiation from the external environment.

In addition to the thermal insulation layer, the prefab panel tank may also include a radiant barrier layer to further suppress temperature fluctuations of the fluid within the prefab panel tank. The emissive barrier layer is reflective to heat radiation (such as visible light or infrared waves) and thus reduces heat transfer. The radioactive barrier layer optionally comprises a very thin mirror-like aluminum foil. Alternatively, the outer side of the first unit panel may be treated with a low heat transmission material such as chromium oxide and Iriotec pigments.

The prefabricated panel tank may also include a fireproofing layer that encapsulates the thermal insulation layer when the thermal insulation material such as cellulose, polyurethane foam, and polystyrene is flammable. The fire protection layer is preferably compatible with the thermal insulation material. For example, hexabromocyclododecane (HBCD) is used to prepare fire protection layers when polystyrene is selected as the thermal insulation material.

In some implementations, the fire protection layer includes a plurality of fire protection sheets. One or more fire protection sheets are attached to the first unit panel or the second unit panel. The fire protection sheets are further assembled together into the fire protection layer while or after the first unit panel and the second unit panel are incorporated together into a prefabricated panel tank. As a result, the thermal insulation sheets are sandwiched between the first unit panel and the fire protection sheets. Alternatively, the fire protection layer is fabricated as a monolithic part and attached as a whole to the outer side of the prefabricated panel tank after the first unit panel and the second unit panel are joined together.

The prefabricated panel tank optionally further comprises a thermal insulation layer and a shielding layer to protect the fire protection layer. The shielding layer is made of a structural material that withstands loads and impacts.

Iron further includes wrought iron, cast iron, steel, and stainless steel. Concrete further includes reinforced concrete and pre-stressed concrete. The shielding layer is optionally positioned externally to the thermal insulation layer and the fire protection layer.

The prefabricated panel tank optionally further comprises a cover, an access hole (eg, a manhole), a ladder, or a combination of the aforementioned objects. The cover is used to partially or completely cover the prefab panel tank to prevent foreign contaminants. The cover optionally comprises a plurality of cover unit panels assembled and/or incorporated together into a single unitary piece of the cover. Alternatively, the cover may be a pre-fabricated part and may be loaded as a whole onto the side wall of the prefabricated panel tank. The access hole is manufactured as an opening for accessing the interior space of the prefabricated panel tank by an operator or technician for testing, maintenance, or even modification (eg, upgrading). The access hole is preferably located near the peripheral edge of the prefabricated panel tank of the cover for easy access. The ladder has its lower end at or near the ground; And a top end at the cover, or slightly higher than the cover. In particular, the top end is near the access hole so that the operator can easily reach the access hole by climbing the ladder up to the top end.

The prefabricated panel tank may optionally be a framework (e.g., structural) connected to either a first unit panel, a second unit panel, or both detachably or permanently to maintain the structural integrity of the prefabricated panel tank. It further includes bracing). For example, structural bracing may include inner bracing and/or outer bracing. Inner bracing and outer bracing are often made of steel or even polymers (such as steel rods) capable of suppressing the designed pressure. The framework optionally consists of wood, engineered wood, concrete, structural steel, or a combination of any of these. Additionally, the framework includes a side frame detachably connected to the side wall of the prefabricated panel tank. The side frame may be a steel beam structure, a portal frame structure (also known as a goal post structure), or a box frame structure (also known as a picture frame structure), or a cage frame ( cage frame) structure may be further included. The box frame structure is particularly suitable as a number of horizontal bars and a number of vertical poles are joined together to create a box frame structure. In addition, the framework may also include a roof beam detachably connected to the cover of the prefabricated panel tank to maintain the shape of the cover.

The prefabricated panel tank optionally further comprises an outer base (also known as a structure) for supporting the framework. For example, a prefab panel tank includes a concrete foundation (such as a concrete flat foundation or plinth spaced at regular intervals) as an outer foundation for supporting the prefab panel tank containing the framework. . The outer foundation may also include an I-shaped (double-T) foundation, a slab-on-ground foundation, or a frost protected foundation. One or more corner bracings (such as angle bars) are applied at the outer base to structurally support the base. Corner bracing has a shape and size that is adaptable to a specific base.

The framework includes at least one rod, shaft, or tie rod connecting or fixing inner sides of two opposing unit panels. In contrast to the side frame that is detachably connected to the outer side of the prefab panel tank, the rods are the inner sides of the two first unit panels at the opposite sides of the prefab panel tank (i.e., opposite first unit panels). It is fixed inside the prefab panel tank by connecting it to the field. Additionally, some internal bracings are tied diagonally to the unit panel.

The prefab panel tank optionally includes one or more sensors for monitoring the operation status (such as water level) of the prefab panel tank, communication modules (e.g., Internet-of-Things IoT device). , Or a combination thereof. Additionally, the prefab panel tank may also have a warning device connected to sensors and/or communication modules to generate a warning signal (such as sound or light) to an operator of the prefab panel tank. In addition, the prefab panel tank may include solar panels for generating and providing electrical power to other components such as sensors and communication modules.

The prefabricated panel tank optionally further comprises a drainage panel having a drainage hole, orifice, or valve for discharging fluid away from the prefabricated panel tank. In some embodiments, the drain hole is positioned at the bottom of the prefab panel water tank to automatically drain the fluid due to gravity. In addition, the prefab panel tank may also have an inlet for filling fluid into the prefab panel tank, an overflow pipe for dispersing fluid from the prefab panel tank, and when the prefab panel tank is sealed when it is in operation. May include an air vent for ventilation or pressure relief.

The prefabricated panel tank optionally further comprises a cross connector (eg, T-bracket) configured to merge the four corners of neighboring unit panels together. The cross connector provides an additional mechanical force to coalesce the unit panels, thus making the prefab panel tank a monolithic storage device.

The prefabricated panel tank optionally further comprises an inner partition or board for providing an inner portion of the prefabricated panel tank. In this way, the prefab panel tank is divided into a plurality of smaller and independent cells for storing the same liquid or different liquids. Therefore, each cell can be configured, maintained, tested, and repaired without any interference from any other cell. Additionally, the lining can also be individually incorporated or attached to the interior partition to prevent communication of liquids from the cells.

The prefabricated panel tank optionally further comprises a base frame for holding the prefabricated panel tank in a building area (eg, ground, rooftop). The base frame is attached to at least one of detachably or permanently to the bottom of the prefabricated panel tank. Additionally, the base frame is optionally connected to the outer foundation and/or framework of the prefabricated panel tank.

In addition to the side wall, the prefabricated panel tank may further include a lower end having a lower extension. The bottom and side walls are directly incorporated in the bottom extension and side walls. For example, the first unit panel further includes a side extension (such as a side flange) that mates with a lower extension (such as a lower flange) at the bottom. The lower and first unit panels are directly incorporated by fixing the side extensions and the lower extensions together. In some implementations, the side extension folds in a horizontal direction and is thus parallel to the bottom. In some implementations, the lower extension folds in a vertical direction and is thus parallel to the first unit panel.

Plastic welding alone can incorporate the bottom seam between the bottom extension and the side extension. Additionally, the prefab panel tank also includes a bottom seal or bottom protector applied in the bottom seam (also known as the bottom gap or bottom coalescence) between the bottom extension and the sidewall. The bottom sealant is applied to the bottom seam between the bottom extension and the side extension on the inner side and the inner side of the bottom of the first unit panel, respectively. The bottom sealant is similar to the sealant in the shim between the first and second extensions. Bottom sealant is used to provide additional assurance that there is no leakage at the bottom seam. Bottom sealant is particularly important in scenarios where plastic welding cannot reach standard quality.

The bottom sealant is formed by any suitable method depending on the specific material of the bottom sealant. For example, the bottom sealant is produced by a thermoplastic welding method. The thermoplastic welding method is performed by mechanical welding means, thermal welding means, electromagnetic welding means, or chemical welding means (also known as solvent welding). Mechanical means include, but are not limited to, ultrasonic welding (20-40 kHz), stir welding (1-100 kHz), vibration welding (100-250 Hz), and spin welding (1-100 Hz). Electromagnetic welding means include, but are not limited to, induction welding (5-25 MHz), microwave welding (1-100 GHz), dielectric welding (1-100 MHz), and resistance, injection, or electrofusion. . Thermal welding means are hot gas welding (such as tack welding and rod welding), extrusion welding, infrared welding, laser welding, hot wedge welding, and hot plate or butt fusion. fusion) welding. Thermoplastic welds are inspected by using various methods to test weld integrity. Methods include creep test (such as creep rupture test and tensile creep test), impact test, shear test, peel test (BS EN 12814-4), bend test (DVS). 2203-1 and DVS), tensile test (DVS 2203-5), and hydrostatic pressure test (ASTM). For example, thermoplastic welds are inspected by a non-destructive test (NDT) to ensure the weld quality at the bottom. Non-destructive tests include, but are limited to, holiday spark tests, ultrasonic tests, leak-tightness tests, radiography, and visual tests (DVS 2202-1). It doesn't work. In particular, the non-destructive test includes a holiday flame test to identify unacceptable discontinuities such as pinholes, holidays, bare spots, or thin points.

The bottom for the prefab panel tank can contain a single component of any load holding material (such as concrete, metal, or compacted soil), and the lining is attached thereon to interface with the unit wall panel. do. A single component of the bottom may include one or more weight-holding parts such as a stainless steel plate, a sump, and a bound soil plate to provide a flat bottom surface. The lining is then applied to completely cover the flat bottom surface; The prefab panel tank is then built directly on the lining and flat bottom surface. This technique is particularly used for oil storage tanks and chemical waste tanks. Alternatively, the lower end of the prefabricated panel tank may also include a third unit panel and a fourth unit panel similar to the first unit panel or the second unit panel. The third and fourth unit panels are joined together to form a lower end. For example, the lower extension includes a third extension (such as a third flange) and a fourth extension (such as a fourth flange) at peripheral edges of the third unit panel and the fourth unit panel, respectively. The third extension and the fourth extension are joined together to form a lower end. In some embodiments, the bottom of the unit panels is supported above the ground by a plinth or other heavy base. It is understood that the unit wall panels are not limited to a square shape, but may be of any other shapes suitable for constructing a container (eg, a cylindrical container).

Similarly, the prefab panel tank may further comprise a roof. In particular, the loop is made of a material that is chemically resistant to chlorine gas or other corrosive chemicals containing chlorine groups. Similar to the bottom of a prefabricated panel tank, the roof can be made of a single component (such as a monolithic covering), or by a plurality of unit panels having top extensions (i.e., top unit panels). Can be assembled. Similarly, the top extensions are joined together to form a loop. The top extensions are either inward (i.e., the top extension extends or points to the inner side of the prefab panel tank) or outward (i.e., the top extension extends or points from the outer side of the prefab panel tank). Can be coalesced in the upper coalescing parts by means of the spools. In the former case, the human or test machine often walks on the roof, so one or more support structures (such as steel bars) are provided under the roof to support the top unions. In the latter case, a flat and strong structure can be laid on the roof to cover the top unit panels and top unions for a human or test machine to walk on the roof. Additionally, one or more support structures (such as steel bars) are provided at the top extension for supporting the loop. On the other hand, the roof and sidewall are directly incorporated in the top extension and sidewall. For example, the first unit panel further includes a side extension (such as a side flange) that mates with a top extension (such as a top flange) of the roof. The roof and the first unit panel are directly incorporated by fixing the side extensions and the top extensions together. In some implementations, the side extension folds in a horizontal direction and is thus parallel to the loop. In some implementations, the top extension folds in a vertical direction and is thus parallel to the first unit panel. It is noted that all of the above techniques of incorporating the bottom and side walls (such as plastic welding) are also suitable for incorporating the roof and side walls.

The prefabricated panel tank optionally comprises fastening means for securing the first extension and the second extension of the side wall. For example, the first extension and the second extension each have a first engagement hole and a second engagement hole. The first engagement hole and the second engagement hole are mated with each other in terms of size and position. The fixing means includes an engaging screw and an engaging nut. The engagement screw passes through the first and second engagement holes from the first extension, and is then rested on the first extension by the slotted head of the engagement screw. Then, the engagement nut fixes the engagement screw from the second extension on the thread of the engagement screw, thereby fastening the first fastening means. Additionally, the fastening means may further comprise a reinforcing plate arranged between the first extension and the slotted head of the engagement screw to avoid damage to the first extension. Similarly, the prefabricated panel tank includes another fastening means for securing the lower third extension and the fourth extension.

The first fixing means and the second fixing means may each comprise a first coating and a second coating to prevent any leakage from the first and second extensions. The first coating and the second coating are optionally compatible with the lining when covered by the lining. For example, the first and second coatings are made of a thermoplastic material such as FEP, PFA, or UHMWPE. In particular, the first coating or the second coating is integrated with the first lining or the second lining to form a monolithic component by any of the methods described above (such as co-extrusion).

The prefabricated panel tank optionally includes a fixture for fixing the side extension and the bottom extension. Similarly, the fixture may also include a fixing coating compatible with linings such as thermoplastic materials including FEP, PFA, or UHMWPE. In particular, the fixed coating is also integrated with the lining as a monolithic component by any method described (such as co-extrusion).

As a second aspect, the present application also discloses a prefabricated unit panel for the prefabricated panel tank of the first aspect. The pre-fabricated unit panel includes a structural panel having an extension; And a preformed lining sheet on the inner side of the structural panel to completely cover the structural panel comprising the extension. The lining sheet optionally comprises a thermoplastic material (such as FEP, PFA, or UHMWPE); The structural panel is optionally, metals (such as stainless steel, copper, bronze, brass, or galvanized steel) or metal alloys, plastics (such as polyethylene or polypropylene), (glass fiber reinforced plastics (FRP) or Glass reinforced plastics (GRP)).

Similar to the lining of the first aspect, the lining sheet comprises a base layer of a first color and a front layer of a second color, so that the erosion of one of the layers (such as the front layer) is a premature wear or a visual point of damage. Another layer (such as the base layer) will be exposed for testing.

Similar to the fastening means of the first aspect, the extension optionally comprises an engaging hole for fastening means such as an engagement screw and an engagement nut. Thus, the lining sheet may include through holes that mate with the engagement holes of the extension in terms of size and location for the fixing means. Therefore, the extension part and the lining sheets of one prefabricated unit panel are fixed together with the extension part and the lining sheets of another prefabricated unit panel by fixing means.

As a third aspect, the present application also discloses a method of manufacturing a side wall for the prefabricated panel tank of the first aspect. A method of manufacturing may include providing a first unit panel having a first extension at a peripheral edge thereof; Providing a second unit panel having a second extension portion at a peripheral edge thereof; Directly assembling the first unit panel and the second unit panel together by fixing the fixing means at the first and second extension parts; And applying a sealant in the seam between the first and second extensions on inner sides of the first unit panel and the second unit panel. The sealant is applied by any suitable method discussed in the first aspect. When made of glass fiber reinforced plastics (FRP), the first unit panel and the second unit panel are sheet molding compounds (such as compression molding), hand laid, (injection molding, transfer molding) , And bulk molding compounds, such as compression molding, and compression molding. In particular, the applying step may comprise a thermoplastic welding process. The thermoplastic welding process is optionally carried out by mechanical welding means, thermal welding means, electromagnetic welding means, or chemical welding means.

The method of manufacturing optionally includes the step of incorporating or attaching the lining onto the inner sides of the first unit panel and the second unit panel. The lining has all the properties described in the first aspect. The lining can be used in any suitable method including, but not limited to, injection molding, pultrusion, rotational molding, compression molding, extrusion, thermoforming or vacuum forming, calendaring, and blow molding. Prepared by In particular, the step of incorporating optionally includes a thermoforming process. The method of making optionally further comprises the step of inspecting the sealant by non-destructive testing. Non-destructive testing includes holiday flame testing.

The method of manufacturing optionally includes selecting a lining to withstand corrosion of a predetermined host. For example, the lining is step-grown (such as polyester, polyamide, or polycarbonate) when the prefab panel tank stores an acid solution or a base solution as a predetermined host. It is chosen not to consist of (step-growth) polymers. Additionally, the method of manufacturing also optionally includes coating the fixing means to avoid leakage of the predetermined host. Preferably, the coating consists of the same or similar material with a lining for easily and firmly incorporating the coating and lining together. In some embodiments, the coating and lining are integrated together as a monolithic component before they are incorporated onto a unit panel.

The step of incorporating comprises a first step of providing a front layer and a base layer; A second step of co-extruding the front layer and the base layer to form a homogeneous bonded layer; And a third step of attaching the homogeneous bonded layer onto the inner side of the first unit panel. As described above, the front layer has a front color; The base layer has a base color different from the front color for easy visual examination. In particular, the step of coalescing includes combining the lining onto the first and second extensions in order to directly coalesce the first unit panel and the second unit panel. In this way, the manufacturing method does not require any gasket inserted between the first and second extensions. Therefore, existing problems with gaskets such as leakage and corrosion are overcome; The first unit panel and the second unit panel are merged more closely and durablely in the first and second extension parts.

As a fourth aspect, the present application also discloses a method of incorporating individually lined prefabricated panel tanks having two parts in the case of thermosetting linings such as PVC, ABS, PMMA (acrylic), etc. The method of merging includes pressing two parts; And applying a sealant in the shim between the two parts. The two parts of the prefab panel tank are pressed tightly together so that the shim has a dimension of less than 0.5 millimeters (mm) to create a capillary effect. The sealant is in a liquid state and then enters the shim due to the capillary effect. The sealant is finally fixed in the sealant and completely covers the shim to prevent any leakage. For example, a solution with dissolved or suspended resin enters the shim due to the capillary effect; Next, the resin is fixed in and near the shim by solvent welding.

As a fifth aspect, the present application also discloses a method of repairing an existing prefabricated panel tank. Existing prefab panel tanks have a bottom and a side wall as two parts. A method of repair includes providing a lining; Applying a sealant at the seam between the lower end and the side wall; And attaching the lining to the inner surface of the existing prefabricated panel tank. Since the inner surface of the existing prefabricated panel tank includes the bottom surface of the bottom and the side surface of the sidewall, the lining completely covers both the bottom surface and the side surface to prevent any leakage.

When the lining has a larger dimension than the inner surface of an existing prefabricated panel tank, the lining is then attached to the inner surface as a whole. In particular, the lining covers the sealant in the shim without any coalescence process. The lining needs to be soft and flexible in order to fit into an existing prefab panel tank. For example, the lining includes a thermoplastic material. Prior to attaching the lining to an existing prefabricated panel tank, the thermoplastic material can be softened by heating at a temperature slightly above the glass transmission temperature of the thermoplastic material. Alternatively, some materials with lower heating requirements (such as PE and PP) do not require this softening step. The softening step also depends on the shape and design of the host unit panels. Alternatively, the lining optionally comprises a plurality of lining sheets. Each of the lining sheets has a smaller dimension than the inner surface of an existing prefab panel tank. In this case, the method of repairing further comprises the step of bringing together the lining sheets for completely covering the inner side of the existing prefabricated panel tank.

Existing prefabricated panel tanks may be cube tanks having a rectangular or square shape in cross section, having four side surfaces (ie, a front surface, a rear surface, a left surface, and a right surface). Thus, the cube tank has four coalescence parts around the side surfaces, i.e. a first coalescence part between the front and right surfaces, a second coalescence part between the right and rear surfaces, and a third coalescence part between the rear and left surfaces. It has a mating part, and a fourth mating part between the left surface and the front surface. The repair method consists of 4 bonds in each of the 4 unions, i.e., the first bond in the first bond, the second bond in the second bond, the third bond in the third bond, and the fourth bond. It further comprises the step of applying a fourth bond in the union.

The shim of the cube tank consists of four linear shims, i.e. the first linear shim between the front and bottom surfaces, the second linear shim between the right and bottom surfaces, the third linear shim between the rear and bottom surfaces, and the left side. And a fourth linear shim between the and the bottom surface. The sealant accordingly comprises a first sealant, a second sealant, a third sealant, and a fourth sealant in the first linear shim, the second linear shim, the third linear shim, and the fourth linear shim respectively. Includes.

In comparison, existing prefabricated panel tanks are cylindrical with only one side surface closed on themselves with one or more coalesces depending on the size of the liner available under current manufacturing capabilities. You can have a tank. Therefore, the shim of the cylindrical tank contains only one circular shim between the bottom surface and the side surface.

The applying step optionally includes a thermoplastic welding process when the lining comprises a thermoplastic material. Thermoplastic welding processes include mechanical welding means, thermal welding means, electromagnetic welding means, or chemical welding means. In particular, hot gas welding can be done to temporarily weld several selected spots; In contrast, extrusion welding is used to coalesce the lining sheets of the first and second unit panels expressing the necessary features of the present application. In extrusion welding, the molten thermoplastic filler is conveyed from the barrel of a hand-held extruder through a shaped PTFE shoe to match the profile of the coalescence. The lining is first rolled to fit the cylindrical tank, and then, the two ends of the cylindrical tank are superimposed and finally welded together. Extrusion welding is a fast and convenient welding technique and can also be done continuously.

The method of repairing may further include inspecting the prefab panel tank by non-destructive testing. Non-destructive testing may also include performing a holiday flame test.

The method of repairing may further comprise selecting a lining according to an existing prefab panel tank. The method of repairing may also include selecting a lining to withstand corrosion of the predetermined host.

The step of attaching optionally includes a first step of providing a front layer and a base layer; A second step of co-extruding the front layer and the base layer as a homogeneous bonded liner; And a third step of attaching the homogeneous bonded liner to the inner side of the prefabricated panel tank. As described above, the front layer has a front color; The base layer has a base color different from the front color for easy visual examination.

As a sixth aspect, the present application also discloses a method of manufacturing a prefabricated unit panel for the prefabricated panel tank described in the second aspect. A method of manufacturing a pre-fabricated unit panel includes: providing a structural panel having an extension; Providing a lining sheet that is larger than the structural panel; And attaching the lining sheet onto the inner side of the structural panel. In particular, the lining sheet completely covers the extension of the structural panel.

The lining optionally comprises a thermoplastic material. Thus, the attaching step can be done by a thermoforming method suitable for the thermoplastic material.

The lining optionally includes a front layer having a front thickness and a base layer having a base thickness. In some implementations, the front thickness accounts for about 50% of the total thickness, such as in the range from 150 to 200 microns.

Structural panels consist of metals (such as stainless steel, copper, bronze, brass, galvanized steel, aluminum, titanium, etc.) or metal alloys, plastics (such as polyethylene or polypropylene), and glass fiber reinforced plastics (FRP). Or composites such as glass reinforced plastics (GRP) carbon fiber), which are impermeable, corrosion resistant, and structurally robust.

The method of manufacturing a prefabricated unit panel optionally includes attaching a thermal insulation layer on the outer side of the structural panel to reduce temperature fluctuations.

1 illustrates a partially exploded view of a first prefabricated panel tank 100 having an outer base 130. The first prefabricated panel tank 100 includes a bottom 102, a roof or cover 104, and a front wall 106, a rear wall 108 (not shown), a left wall 110 (not shown), And a cube dimension with four side walls including a right wall 112. Therefore, twelve (12) edges 138 are formed for the first prefabricated panel tank 100. The bottom 102, the cover 104, and the sidewalls 106, 108, 110, 112 are assembled by a plurality of unit panels 114 incorporated together. The first prefabricated panel tank 100 includes an access hole or manhole 116 at the corner of the cover 104, a ladder 118 fixed to the right wall 112, and a drain hole 120 connected to the drain tube 122. , Further comprising an inlet 124 and an outlet 126 in the upper and lower parts of the front wall 106, respectively.

Additionally, the outer base 130 is placed on the ground to support the first prefabricated tank 100; The outer framework 132 is connected to a plurality of unit panels to maintain the structural integrity of the prefabricated panel tank 100. The prefabricated panel tank 100 stores a liquid 134 (not shown) within a space defined by a bottom 102, a top 104, and four sidewalls 106, 108, 110, 112. Is used for. Liquid 134 is filled into and discharged from the space through inlet 124 and outlet 126. Additionally, liquid 134 is removed from the space through drain tube 122 and drain hole 120 in a faster manner.

2 illustrates a partially exploded view of a first prefabricated panel tank 100 without an external base 130. All features of the first prefabricated panel tank 100 are the same as those in FIG. 1, except that the lower end 102 is not required. A bonded and flat soil plate (not shown) is prepared from the ground; Next, the pieces of lining 136 are bound and dispersed on a flat soil plate. The first prefabricated panel tank 100 is built directly on the lining 136 by erecting the side walls 106, 108, 110, 112 and incorporating the cover 104 with the side walls 106, 108, 110, 112 do. This first prefabricated panel tank 100 in FIG. 2 is particularly used for oil storage and chemical waste treatment.

3 illustrates an isometric view (FIG. 3A) and a cross-sectional view (FIG. 3B) of the first unit panel 200. The first unit panel 200 includes a first structural panel 202, a first lining sheet 204, a first thermal insulation layer 206, and a first extension part 208. Each of the first extension parts 208 includes four flanges folded at substantially 90 degrees at the four peripheral edges of the first unit panel 200, that is, the first front flange 210 folded at the first front edge 212. ), a first rear flange 214 folded at the first rear edge 216, a first left flange 218 folded at the first left edge 220, and a first right flange folded at the first right edge 224 It further includes (222). The first structural panel 202 thus extends between the four flanges 210, 214, 218, 222. The first structural panel 202 is made of stainless steel that is impermeable, corrosion resistant, and mechanically tough to withstand the pressure of the fluid 134. The four flanges 210, 214, 218, 222 are formed by folding the four edges 212, 216, 220, 224 respectively by substantially 90 degrees. In other words, the four flanges 210, 214, 218, 222 are positioned substantially perpendicular to the four edges 212, 216, 220, 224, respectively. In particular, the first structural panel 202 has a size of less than 4 square meters and a thickness of about 2 millimeters (mm); The first lining sheet 204 also has a thickness of about 2 millimeters (mm). Therefore, the first unit panel 200 has a total thickness of about 4 millimeters (mm).

As shown in FIG. 3B, the first lining sheet 204 has two flat sides, a first side 242 and a second side 244. The first side portion 242 is incorporated into the inner surface 226 of the first structural panel 202 to form the first unit panel 200 by a thermoforming method. In particular, the first lining sheet 204 completely covers the inner surface 206 comprising the first structural panel 202 and the first extension 208. The first lining sheet 204 is made of a thermoplastic material such as UHMWPE. Since it is in direct contact with the liquid 134, the first lining sheet 204 is required to be water-proof and corrosion resistant to water and almost all chemical solutions. A first thermal insulation layer 206 is formed on the outer surface 228 of the first structural unit panel 202 to reduce temperature fluctuations of the fluid 134. The first thermal insulation layer 206 is made of glass fibers that are light in weight and hydrophobic to water. In addition, the first unit panel 200 includes a relief portion 230 on the first structural panel 202 to further enhance mechanical properties of the first structural panel 202.

As described above, a plurality of unit panels 114 are joined together to form the first prefabricated panel tank 100. Therefore, the second unit panel 250 is provided to be incorporated with the first unit panel 200. The second panel 250 is the same as the first unit panel 200 as described in FIG. 2. In other words, the second unit panel 200 includes a second structural panel 252, a second lining sheet 254, a second thermal insulation layer 256, and a second extension 258. The second extension 258 is at the second front flange 260 folded at the second front edge 262, the second rear flange 264 folded at the second rear edge 266, and the second left edge 270. It further includes a folded second left flange 268, and a second right flange 272 folded at the second right edge 274. The second lining sheet 254 and the second thermal insulation layer 256 are formed on the inner surface 276 and the outer surface 278 of the second unit panel 250. The second unit panel 250 also includes a second relief portion 280 to further enhance mechanical properties of the second structural panel 252.

4 illustrates a cross-sectional view of the first unit panel 200 having studs 240. The first lining sheet 204 is made of a first side 242 having a plurality of studs 240 and a second side 242 having a flat surface. The first side 242 is assembled towards the first structural panel 202; The second side portion 242 directly contacts the water stored in the first unit panel tank 100. A continuous gap 246 is thus formed between the first structural panel 202 and the first side 242 of the first lining sheet 204. Porous filler 248 (such as aerogel) is filled inside the gap 246 to provide a thermal insulation function and a mechanical cushioning function. The thermal insulation function ensures that the first prefabricated panel tank 100 is still operable in cold winter high latitude countries, or for special applications (such as spas). The mechanical cushioning function ensures that the first lining sheet 204 is pushed tightly against the first structural panel 202 under the pressure of water stored inside the first prefabricated panel tank 100. In particular, the first lining sheet 204 in the flanges 210, 214, 218, 222 is studs 240 at the first side 242 to be closely and reliably incorporated with the first structural panel 202. ).

5A is a view of two unit panels 200 and 250 vertically joined together to form sidewalls 106, 108, 110, 112 of the first prefabricated panel tank 100 in FIGS. 1 and 2 Illustrative cross-sectional view. The second unit panel 250 is the same as the first unit panel 200 and thus has all the features shown in FIG. 3. The second unit panel 250 includes a first structural panel 202, a first lining sheet 204, and a second structural panel 252 and a second lining sheet 254 identical to the first thermal insulating layer 206, respectively. ), and a second thermal insulation layer 256.

The first unit panel 200 and the second unit panel 250 are joined at the joining portion 290 between the first rear flange 214 and the second front flange 260 by a thermoplastic welding method. Additionally, a fastener 235 (such as a screw) also binds the first rear flange 214 and the second front flange 260 at the mating portion 209.

5B illustrates an enlarged cross-sectional view of the coupling portion 290. It is clearly seen that the first rear flange 214 and the second front flange 260 are joined together in the mating portion 290. Specifically, the first lining sheet 204 and the second lining sheet 254 are pressed so as to directly contact at the union portion 290. The union 290 includes a shim 292 even if the first lining sheet 204 and the second lining sheet 254 are pressed close to each other. Thermoplastic welding introduces a sealant 294 for joining the first lining sheet 204 and the second lining sheet 254. The sealant 294 is so strong and reliable that the coalescence portion 290 can seal the liquid 134 during the life of the first prefabricated panel tank 100. In contrast to traditional techniques, a gasket is not required to prevent any leakage from the coalescence portion 290. Additionally, the first thermal insulation layer 206, the first relief portion 260, the second thermal insulation layer 256, and the second relief portion 280 are terminated outside the coalescence portion 290.

6 illustrates an enlarged cross-sectional view of the lining sheets 204 and 254. The lining sheets 204 and 254 include a first layer 296 attached on the inner sides 226 and 276 of the unit panels 200 and 250; And a second layer 298 attached on the first layer 296. In this way, the second layer 298 contacts the liquid 134 stored inside the first prefabricated panel tank 100. The first layer 296 and the second layer 298 have a first thickness 297 and a second thickness 299 of 200 micrometers and 1.8 millimeters, respectively. The first layer 296 and the second layer 298 are both made of the same thermoplastic material such as UHMWPE for easy and reliable attachment. Therefore, the lining sheets 204 and 254 are double protected against liquid leakage, since both the first layer 296 and the second layer 298 are waterproof. In particular, the first layer 296 has a blue color; The second layer 298 has a black color. Any erosion or destruction of the second layer 298 will uncover the first layer 296 for easy visual testing. When the first color is observed on the inner sides 226, 276 of the unit panels 204, 254, the second layer 298 needs to be replaced or repaired as it has already been eroded or destroyed. Similarly, the unit panels 200 and 250 are also horizontally merged together to form the bottom 102 and/or cover 104 of the first prefabricated panel tank 100.

7 illustrates a cross-sectional view of two unit panels 200 and 250 joined at an orthogonal or substantially right angle to form the edge 138 of the first prefabricated panel tank 100.

The additional unit panel and the first unit panel 200 or the second unit panel 250 are the same, but belong to two adjacent sidewalls 106, 108, 110, and 112. In other words, the additional unit panel, the first unit panel 200, and the second unit panel 250 are all positioned orthogonally, and are joined together at the corners of the first prefabricated panel tank 100.

Alternatively, FIG. 8 illustrates a cross-sectional view of the bent unit panel 400. The bent unit panel 400 is provided to form the edge 138 of the first prefabricated panel tank 100.

The bent unit panel 400 is orthogonally or substantially bent at a right angle at the bent portion 402. Accordingly, the bent unit panel 400 has a first portion 404 and a second portion 406. The bent portion 402 is positioned at the edge 138 of the first prefabricated panel tank 100. Whereas the first portion 404 is incorporated with the first unit panel 200 to form sidewalls 106, 108, 110, 112; The second portion 406 is incorporated with the second unit panel 250 to form the bottom 102 or cover 104.

Similar to the first unit panel 200 or the second unit panel 250, the third unit panel 300 includes a third structural panel 302, a third thermal insulation layer 306, and a third extension ( 308). The third extension 308 includes a third front flange 310 folded at the third front edge 312, a third rear flange 314 folded at the third rear edge 316, and a third left edge 320 ( A third left flange 318 (not shown) folded at (not shown), and a third right flange 322 (not shown) folded at third right edge 324 (not shown). . However, the third unit panel 300 does not have a third lining sheet 304 similar to the first lining sheet 204 or the second lining sheet 254.

In addition to the third unit panel 300, the fourth unit panel 350 is provided to be integrated with the third unit panel 300. The fourth panel 350 is the same as the third unit panel 300 as described in FIG. 9. In other words, the fourth unit panel 300 includes a fourth structural panel 352, a fourth thermal insulation layer 356, and a fourth extension part 358. The fourth extension 358 is at the fourth front flange 360 folded at the fourth front edge 362, the fourth rear flange 364 folded at the fourth rear edge 366, and the fourth left edge 370.

10 is a cross-sectional view of two unit panels 300 and 352 vertically incorporated to form side walls 106, 108, 110, 112 of the first prefabricated panel tank 100 in FIG. 1 or 2 Illustrate. The third unit panel 300 and the fourth unit panel 350 are joined at the joining portion 390 between the third rear flange 314 and the fourth front flange 360 by a metal welding method. The union 390 includes a shim 392 even if the third rear flange 314 and the fourth front flange 360 are pressed in close proximity to each other. Metal welding introduces a sealant 394 for joining the third rear flange 314 and the fourth front flange 360. In contrast to traditional techniques, a gasket is not required to prevent any leakage from the coalescence 390. In order to further extend the life of the first prefabricated panel tank 100, instead of the two lining sheets 204, 254 joined together, a single and continuous lining 340 is used as a third unit to prevent any leakage. It is used to cover the inner surface 326 of the panel 300, the inner surface 376 of the fourth unit panel 350, and the coalescence portion 390. Similarly, the unit panels 300 and 350 are also horizontally merged together to form the lower end 102 and/or the cover 104 of the first prefabricated panel tank 100.
