The present invention relates to a prefabricated rainwater storage facility and a construction method thereof, and more particularly, to a pipe unit which is formed of a lightweight plastic material and forms a fluid movement hole so that rainwater can be easily moved in the transverse and longitudinal directions. Assembling to form a rainwater storage frame, and easy to install the prefabricated rainwater storage facility and its construction method that can be installed infiltration-type sheets or order-type sheets on the outside of the finished rainwater storage frame.

In general, due to the increase in buildings and the increase of land surface pavement rate, rainwater flows into sewer or river at once without heavy flooding during heavy rain, and flooding may occur as a result of exceeding inflow capacity. On the other hand, a small inflow of rivers can lead to deterioration in water quality and depletion of groundwater. For this reason, a technology was developed to store rainwater in rainwater storage facilities consisting of concrete or synthetic resin of cast-in-place casting and to control the amount of runoff into rivers.

However, the rainwater storage facility, which is composed of concrete or synthetic resin and is constructed by on-site casting, has no countermeasure in case of flooding of stored rainwater as well as delay of construction period due to on-site pouring.

Accordingly, in the Republic of Korea Patent Registration No. 485742 (invention name: excellent storage tank), as shown in Figure 1, the pillars are provided at right angles to each of the four front, rear, left, and right sides of the top plate and the bottom plate at right angles.

The rainwater accumulated in the unit for the peripheral portion by a screw member extending outward from the unit gradually By presenting a slab with a drain hole to be drained to the basement to suggest an excellent storage tank for easy construction.

However, in the Republic of Korea Patent Registration No. 485742, the unit for the main body and the unit for the peripheral part have a hassle to make a formwork separately when manufacturing the factory, and by constructing the material of the units in concrete, Due to the need for a crane, construction is not easy, and as shown in FIG. 1B, a guide groove for inserting a fastener near each vertex, a difficulty in forming a form due to the complexity of the shape, such as the configuration of each pillar, etc. There is a problem that is not easy in manufacturing a factory.

Accordingly, an object of the present invention for solving the above-mentioned problems is a rainwater storage frame without any fastening device by using a pipe unit formed of a plastic material having the same shape, easy factory production, and light weight in a prefabricated rainwater storage facility. The purpose of the present invention is to provide a prefabricated rainwater storage facility and construction method that can be easily constructed and shorten air.

In addition, another object of the present invention is to configure the pipe unit in the shape of a spiral wave tube or double wall tube to improve the rigidity against buckling, and to provide a prefabricated rainwater storage facility and construction method that is advantageous in the soft ground by the spring action. .

In addition, another object of the present invention is to install the permeable sheet or the order sheet on the outside of the rainwater storage frame formed by the assembly of the pipe unit can be selectively constructed as needed, such as the storage amount of rainwater, the purpose of storing rainwater. To provide a prefabricated rainwater storage facility and its construction method.

Objects of the present invention as described above are attached to the outside of the rainwater storage frame (1) and the rainwater storage frame (1) in which a plurality of units are assembled, and the rainwater flowing out of the building and the like in the inlet pipe (3) In the prefabricated rainwater storage facility for storing rainwater by flowing to

The pipe unit 100 is formed in a tubular shape with both ends open so that a plurality of fluid movement holes 110 are formed in the pipe wall to facilitate fluid movement inside and outside the pipe.

The size and the number of the fluid movement hole 110 can be configured in consideration of construction conditions in the field, and when the construction of a structure having a good rainwater storage rate is desired, the size of the fluid movement hole 110 is increased or the number thereof is increased. You can optionally configure it by way of stretching. However, when the size of the fluid movement hole 110 is increased or the number thereof is increased, the rigidity of the axial load and the lateral load decreases relatively, and consequently, the load should be considered in consideration of the load.

The tube unit 100a may be configured as a spiral wave tube as shown in FIG. 2A. When the spiral wave tube is configured as described above, the buckling stiffness can be excellently configured with respect to the load, and when the rainwater storage frame 1 is formed by assembling the pipe unit 100 on the soft ground, the soft Even if the ground is settled, it can be compensated for by the spring action of the pipe unit 100a configured in the spiral wave shape, and when the pipe unit 100 is stacked and assembled by the top, bottom, left and right of the pipe unit 100 It is also possible to assemble firmly so that the valley and the mountain of the other pipe unit 100 abuts.

In addition, the tube unit 100b may be configured as a double wall tube as shown in FIG. 2B to perform the same function as the case of configuring a spiral wave tube as described above.

In the present invention by forming the rain water storage frame (1) by the stack of the pipe unit 100, rain water is easy to store and move in the hollow portion of each pipe unit 100 and the pipe unit 100 side by side It can be assembled by only stacking up, down, left, and right, no fastening device is required, and as shown in the above embodiment, the pipe unit 100 is composed of a spiral plate-shaped pipe 100a or a double wall pipe 100b. As a result, the stiffness against loading can be improved.

The pipe unit 100 is excellent in resistance to corrosion in terms of material, excellent in weight ratio rigidity, light weight and easy to use plastic material, preferably using fiber reinforced plastic and the like. The fiber reinforced plastics (hereinafter referred to as "FRP") are also called fiber reinforced resins and reinforced plastics. As the reinforcing material, glass fiber carbon fiber and aromatic nylon fiber called Kevlar are used, and the FRP with the glass fiber reinforced is called glass fiber reinforced plastic (hereinafter referred to as "GFRP").

The GFRP is composed of glass fiber, thermosetting resin and sand, and the thermosetting resin uses unsaturated polyester resin, epoxy resin, vinyl ester resin and the like. Unsaturated polyester resins have moderate heat and corrosion resistance compared to other thermosetting resins, but the material price is more economical than other resins. Vinyl ester resins have excellent corrosion resistance and can be selectively used according to construction conditions. In particular, when the unsaturated polyester resin is reinforced with the glass fiber, it becomes a material having great strength and impact resistance. The unsaturated polyester resin itself has a smaller strength than hard polyvinyl chloride and polymethyl methacrylate, but when reinforced with glass fiber, the strength increases as the content thereof increases. Therefore, the GFRP has a higher weight ratio stiffness than steel pipes as well as resistance to corrosion, so that the buckling strength is much stronger than that of steel pipes, and the weight to obtain the same strength will be lower than that of steel pipes. Since much longer pipes can be manufactured on site, the connections at the joints will be smaller, and the air can be shortened.

The reinforcement 200 is a space portion formed between the parts in contact with the finishing material in each pipe unit 100 as the outermost of the rainwater storage frame in the attachment of the rainwater storage frame and the finishing material formed by the assembly of the pipe unit. By the difficulty of the attachment of the finishing material and the rainwater storage frame and the external pressure is to fill the space to prevent tearing of the finishing material.

In addition, as shown in Figure 3b as another embodiment of the present invention by configuring the shape of the reinforcing material (200b) in an inverted trapezoidal shape, although not shown in the drawing inclined to the space portion consisting of the pipe wall of each pipe unit 100 The side surface 210b forming a gradient is settled, and the bottom surface 220b is formed in a flat shape so that each part in contact with the finishing material can be connected to each pipe unit 100 located at the outermost portion of the rainwater storage frame 1. In addition, the upper surface 230b having a side of a length shorter than the bottom surface may be configured to be placed at a predetermined portion of the space portion formed of the tube wall.

In the case of forming the rainwater storage frame 1 by stacking the pipe unit 100, the external pressure acts on the part where both ends and the finishing material of each of the open pipe unit 100 is in contact with the outermost portion of the rainwater storage frame 1. In this case, since both ends of the pipe unit 100 may be opened, tearing of the finishing material may occur, so that the protection member 300 may be further configured to prevent this.

The protective member 300 may be formed in a plate shape and constituted by a single member, and may be installed between both ends of the rainwater storage frame 1 and the finishing material, but may not be easily manufactured due to the enlargement of the member. Assembling on site is easy for factory manufacturing and mold construction.

The protective material 300 may be configured as a form (300b) installed on the middle portion of the rainwater storage frame (1) and the upper and lower surfaces of the rainwater storage frame (1) as an embodiment. The protective material 300a shown in FIG. 4A is installed at the middle portion of the rainwater storage frame 1 as shown in FIG. 5B and has two 1/4 circular convex portions 310a so as to be symmetrically on both sides of one side thereof. The convex portion 310a is inserted into the opened end of the tube unit 100 so that the four convex portions 310a constituted by one protective material 300a are eventually opened. A stage is inserted, and convex portions 310a, b of the respective protective materials 300a, b, which are collected at the reference point x, are inserted into the opened ends of the one pipe unit 100, as shown in FIG. 5B. Protective material 300 performs the function of preventing the tearing of the finish as well as the function of fastening each pipe unit 100. Will be.

In addition, the protective material 300b illustrated in FIG. 4B is installed on the upper and lower surfaces of the rainwater storage frame 1 as shown in FIG. 5B, and each of the one quarter circular convex portions is symmetrically disposed on one surface thereof. By constructing 310b and one 1/2 circular convex portion 310b, the convex portion 310b is inserted into the opened end of the pipe unit 100, thereby forming four protective members 300b. The open ends of the four pipe units 100 are inserted into the two convex portions 310b, the same as the protective material 300a.

The reinforcing member 200 and the protective member 300 is made of a lightweight plastic material, which is lightweight, has excellent buffering properties, and in particular, does not generate methane gas even when buried in the ground, does not contaminate groundwater, and burns it with fire. In addition, it is preferable to use foamed polystyrene, which is an environmentally friendly material that does not generate harmful gases, because only water and carbon dioxide are discharged, and by constructing the reinforcement 200 and the protective material 300 with lightweight foamed polystyrene. When assembling, it can be assembled by manual without requiring any mechanical equipment, so construction is easy and construction cost can be reduced.

It may be preferable to form a descending slope in the direction of the groove 640 so that foreign matters dropped on the bottom easily accumulate in the foreign matter receiver 650 placed in the foreign substance receiver groove 640. When the foreign matter accumulated in the foreign matter receiver 650 is saturated by configuring the foreign matter receiver 650 that can be attached and detached as described above, only the foreign matter receiver 650 can be detached and removed.

On the other hand, it is possible to process the finish on the outside of the rainwater storage frame (1) formed by assembling the pipe unit 100 as described above, the finish material is wrapped around the outside of the rainwater storage frame (1) rainwater storage frame (1) Permeable sheet 400 may be used to allow the rain water stored in the leaching to the outside. The permeable sheet 400 uses a material such as a nonwoven fabric, and it is preferable to use the particle size of the nonwoven fabric according to the ground classification in order to prevent the blockage phenomenon. Here, the occlusion phenomenon refers to a phenomenon in which the soil particles are separated from the soil matrix and are moved by the flow of fluid in the gap of the nonwoven fabric, and then fill the gap of the nonwoven fabric. In order to prevent the rainwater stored in) from leaching into the ground, it is reasonable to adjust the particle size of the nonwoven fabric according to the soil classification. The permeable sheet 400 made of the nonwoven fabric may perform the function of blocking the inflow of foreign substances from the outside into the rainwater storage frame 1 in addition to the function of allowing the rainwater stored in the rainwater storage frame 1 to leach into the ground. It is.

The finishing material may use the order-type sheet 500 to prevent the rainwater stored in the rainwater storage frame (1) can be leached to the outside. The order-type sheet 500 may be made of an EDPM material, etc., and the ground (2) outflow of the rainwater stored in the rainwater storage frame (1) and also prevents foreign matter from entering the interior of the rainwater storage frame (1) When using the order-type sheet 500 as a finishing material to perform a function, it would be desirable to install a separate drain pipe, etc. for the outflow of rain water stored in the rainwater storage frame (1).

When explaining the embodiment of the prefabricated rainwater storage facility of the present invention by using the water-permeable sheet 400 or the order-type sheet as a finishing material as described above with reference to FIG. 400 may be installed on the outside of the rainwater storage frame (1) so that the rainwater can be leached into the ground (hereinafter referred to as "penetration type"), as shown in Figure 7b In order to block the leaching to the ground (2) and to use the stored rainwater for other purposes, the outside of the rainwater storage frame (1) can be wrapped with a degree sheet 500 to store rainwater in the rainwater storage frame (1) It can be configured (hereinafter, referred to as "order type"), the order sheet 500 is because the stored rain water is not leaked to the outside can be damaged by the order sheet 500 due to the pressure of the rain water. So when the pitcher for protection to the inside, outside of the order-type sheet 500 The 400 is preferably further provided. In addition, as shown in FIG. 7C, the "infiltration type" and the "order type" may be used in combination (hereinafter, referred to as "combination type").

In more detail, the rainwater storage frame (1) formed by assembling the pipe unit (100) is buried underground in the case of the penetration type, and the water-permeable sheet on the outside of the rainwater storage frame (1) 400 is constructed. The foreign material removal hole 600 described above is buried in the same line as the ground on the side of the rain water storage frame (1), the inlet pipe (3) to which rain water flows is connected to the side of the foreign material removal hole (600), The other side of the foreign matter removal hole 600 is connected to the foreign matter removal hole 600 and the rainwater storage frame (1) is an outlet pipe (4) for the stored rain water to flow out into the rain water storage frame (1). Above the rainwater storage frame (1) is composed of at least one check hole (7) penetrating the ground, and the foreign matter precipitated by checking the inside of the rainwater storage frame (1) after the posture by the configuration of the inspection hole (7) It will be able to remove the back.

The foreign material removal hole 600 constitutes one or more overflow outflow pipes 5 so that when the rainwater stored in the rainwater storage frame 1 overflows the rainwater storage frame 1, the overflowed rainwater may flow out. It is configured to be. The overflow outflow pipe 5 may be connected to the sewer pipe so as to discharge the overflowing rainwater into the sewer pipe.

When the rainwater is stored and leached by the penetrating type, rainwater flowing through a building, etc., falls through or flows through the inlet pipe 3 or above the foreign substance removal hole 600, and penetrates the cover 620. It is stored in the body portion 610 of the foreign material removal hole through the ball 622. Rainwater stored in the body 610 is automatically settled over time and accumulated in the foreign matter receiving 650, or the foreign matter is removed by the cover filter 621. In addition, the stored rainwater is discharged to the rainwater storage frame 1 through the outlet pipe 4, and the foreign matter is filtered out by the outlet pipe filter 630 installed at the inlet of the outlet pipe 4. Rainwater flowing into the rainwater storage frame (1) through the outflow pipe (4) is the rainwater leaching into the ground (2) through a plurality of fluid movement holes of the pipe unit assembled on the outermost of the rainwater storage frame rainwater rainwater Flooding the storage frame (1) is to prevent in advance to cause flooding. In addition, when the rainwater floods the rainwater storage frame 1 in addition to the leaching as described above, the rainwater stored in the foreign matter removal hole 600 through the outflow pipe 4 of the rainwater storage frame 1 flows backward. The reversed rainwater is discharged to the sewage pipe through the overflow outlet pipe 5. Rainwater leaches into the ground little by little even during rainy weather storage and leaching, so the rainwater does not overflow onto the ground. The infiltration type is more important than the storage of rainwater such as golf courses and sports grounds. It is preferably used in the case. In addition, it is possible to check the storage state of the rainwater in the rainwater storage frame (1) through the inspection opening (7), check for the presence of internal defects and remove foreign matters from the stored rainwater.

In the case of the storage type, the rainwater storage frame (1) formed by assembling the unit is buried underground, and the order-type sheet (500) is constructed on the side and bottom of the rainwater storage frame (1), and the order-type sheet. It is preferable to construct the permeable sheet 400 for protection inside and outside the 400. The debris removal hole 600 and the check hole 7 formed in the upper portion of the rainwater storage frame (1) is formed on the side of the rainwater storage frame (1) is configured the same as the penetration type. However, since the storage type is mainly used to use the rainwater stored in the rainwater storage frame (1) so that the overflow flow pipe (5) at least one of the upper edge of the rainwater storage frame (1) to use the rainwater versatile It is configured to be connected to the orifice receiver (8) that can be stored, and the rainwater stored in the lower portion of the rainwater storage frame (1) should also be discharged so that one or more drain pipes (6) are formed at the lower portion of the rainwater storage frame (1) The drain pipe 6 is configured to be connected to the orifice receiver (8).

When the rainwater is stored and leached by the storage type, the inflow and foreign matter removal by the inflow pipe 3 and the foreign matter removal hole 600 is the same as the infiltration type, but through the outflow pipe 4 Rainwater flowing into the rainwater storage frame (1) is rainwater is not leached into the ground (2) because the rainwater storage frame (1) is wrapped by the order sheet 500 at the side and bottom, but, infiltration into the upper surface Since the seat 400 is installed, the rainwater that overflows the rainwater storage frame 1 is leached only through the upper surface. Since there is no leaching of rainwater as described above, the rainwater pressure acts on the order-type sheet 500, so that a defect may be caused. Thus, the water-permeable sheet 400 may be protected for protection in and out of the order-type sheet 500. It is provided to prevent the leaching of rainwater by the tearing of a sheet | seat, and the like. Rainwater stored in the rainwater storage frame (1) as described above is discharged to the orifice receiver (8) through the drain pipe 6 connected to the lower portion of the rainwater storage frame (1), rainwater stored in the orifice receiver (8) Is used for proper use such as drinking water and fire protection. In addition, the rainwater overflowing the rainwater storage frame (1) through the overflow flow pipe 5 connected to the upper portion of the rainwater storage frame (1) is discharged to the orifice receiver (8). In addition, in the case of the storage type, it is possible to check the storage state of the rainwater in the rainwater storage frame 1, the presence of internal defects, and to remove the foreign matter from the stored rainwater through the check hole 7.

In the case of the combined type, the penetration type and the storage type are used in combination, except that the overflow outlet pipe 5 of the storage type is not connected to the orifice receiver 8 but to the rainwater storage frame 1 of the penetration type. There is a difference in connection.

 When the rainwater is stored and leached by the combination type, the rainwater is stored and leached in the same way as the infiltration type in the part where the rainwater storage frame 1 is embedded, and the storage rainwater storage frame 1 is buried. In the same part, rainwater is stored and leached in the same manner as the storage type. However, the combined type is ground through the overflow pipe (5) configured in the foreign material removal hole 600 in the infiltration type when the rainwater stored in the infiltration rainwater storage frame (1) flooded the rainwater storage frame (1) 2) as well as the rainwater storage frame (1) of the storage type through the overflow flow pipe (5) connecting the rainwater storage frame (1) of the storage type and the infiltration rainwater storage frame (1) of the storage type. The rainwater stored in the rainwater storage frame (1) of the penetration type can be moved, on the contrary, when the rainwater stored in the rainwater storage frame (1) of the storage type overflows, the rainwater storage frame (1) and the penetration type of the storage type Rainwater storage frame of the storage type (1) can be stored in the rainwater storage frame (1) through the overflow flow pipe (5) connecting the rainwater storage frame (1) of the infiltration and storage type Can be used complementarily.

 Meanwhile, as shown in FIG. 8, the present invention attaches a finishing material to the outside of the rainwater storage frame 1 and the rainwater storage frame 1 in which a plurality of units are assembled, and the rainwater flowing out of the building inside the inflow pipe. (3) In the method of constructing a prefabricated rainwater storage facility for storing rainwater by flowing to the back, etc.
