Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upright type retention structure for an excellent storage and an excellent storage facility having the same,

The present invention relates to an upright retention structure for an uptake, and a method of constructing an uptake storage facility and an uptake storage facility having the same.

Increasing the area of the impervious land surface such as asphalt and concrete due to urbanization reduces the amount of water in the soil and causes the overflow or drainage of surrounding rivers. At the same time, it causes the water pollution of the river and destruction of ecosystem .

That is, when there is a river around the area where the impervious ground is widely formed, the rainwater can not penetrate into the soil at the time of rainfall, There is little or no amount of water that the underground soil usually contains. If the water quality of the river is insufficient, the natural purification ability of the river is considerably weakened, and even a slight pollutant causes severe deterioration of the water quality.

On the other hand, various methods for recycling rainwater have been proposed in response to the recent water shortage due to rapid changes in climate. A representative example of such rainwater recycling method is an excellent storage facility. The stormwater storage facility is a large-scale storage tank for receiving rainwater when it is raining and for use when necessary, and is being constructed in most of the newly-developed cities and residential development areas.

The stormwater storage facility receives the increased rainfall during rainfall, temporarily stores it, and gradually discharges it to prevent the river from overflowing or storing it without discharging it, and then pumping it to the outside when necessary.

There are various kinds of rainwater storage facilities for solving various problems due to the increase of the roadway packing rate and for recycling of rainwater.

However, the rainwater storage facility disclosed in the above-mentioned domestic patent has a disadvantage in that it is susceptible to vertical loads and, in particular, lateral loads, due to the large number of fastening points, because it has a structure in which many box-shaped blocks are stacked vertically and horizontally. Even if each block is fastened with a fastening part, the stiffness which can stably withstand the external load is insufficient, and the deflection due to the creep or the like over time can not be controlled sufficiently.

Especially, it is vulnerable to the earthquake due to the weak lateral load, and when it is installed in a region other than the soft ground or the flat ground, it suffers a problem that it is deformed easily due to the constant earth pressure applied from the surroundings.

In addition, since each block is coupled through the fastening fitting, assembly is very troublesome because of a large number of parts, and the time required for the operation is very long, so that the construction period takes much longer. In addition, since the box-shaped block is a hollow product, it has a certain size, and when a large number of blocks are stacked, the volume thereof is very large, and thus the transportability is not good.

Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing an excellent storage facility 11 having an upright storage structure 13 for storable storage according to an embodiment of the present invention.

As shown in the figure, the storm reservoir structure 11 according to the present embodiment includes a reservoir structure 13 to be installed in an underground space secured by excavating the soil S, a base A cover plate 17 disposed on the upper portion of the storage structure 13 and a lapping sheet 21 surrounding the storage structure 13 and the cover plate 17; A manhole 25 disposed at the side of the storm structure 13 for moving the rainwater flowing into the underground storey to the storage structure 13 side and a machine room 27 for pumping the rainwater stored in the storage structure 13 to a necessary place.

The underground space is a space created by a separate excavation operation. The size of the above-mentioned underground space naturally changes according to the environment and needs of the area. The larger the space of the underground space, the more rainwater can be stored.

First, the base 19 is a foundation layer for horizontally and vertically supporting the reservoir structure 13, which can be a sand layer or a gravel layer formed by sand or gravel being flattened, or a concrete slab . ≪ / RTI > If the soil is so soft that it is too humid, you can use sand, pebbles and concrete in combination with two or more. This base 19 provides a solid horizontal support surface to prevent the retention structure 13 from sinking.

The storage structure 13 is constructed by directly connecting a plurality of upright frames 15 and is horizontally supported on the upper portion of the base 19. [ The reservoir structure 13 is firmly positioned horizontally without being depressed by the action of the base 19. [

The upright frame 15 is a columnar frame extruded by using an extrusion apparatus, and forms a storage space 15a capable of storing rainwater underground excavated. Examples of the upright frame 15 include center frames 35 and 43 to be described later, side frames 37, 39, 41, 45 and 47, and the like.

Especially, since the upright frame 15 is formed by the extrusion method, it can be cut to a required length according to the situation in the field, and thus, the construction can be accurately performed. In the case of the conventional storage structure, since a box-shaped block manufactured to a predetermined size is used, the size of the block can not be adjusted according to the situation of the site, but in this embodiment, precision construction can be performed by adjusting the length in the field.

In addition, the storage structure 13 is constructed as a structure that is built up in the excavated underground space with the lapping sheet 21, and once received, stores the rainwater flowing through the manhole 25. The storage structure 13 in this embodiment may have the planar structure of FIG. 2 or 7, and may be implemented in any other form according to the embodiment. The storage structure 13 will be described later in detail.

The cover plate 17 is horizontally disposed on the storage structure 13 as a rigid plate-like member, receives the weight of the soil buried on the top of the storage structure 13, and distributes the load horizontally. Without the cover plate 17, the lapping sheet 21 will not be able to withstand the earth pressure and will tear.

The lapping sheet 21 is a sheet-like member that encloses the storage structure 13, the cover plate 17, and the base 19. In particular, the lapping sheet 21 may be a permeable sheet that transmits water, or may be a car-shape sheet that does not allow water to pass therethrough.

Whether to use the infiltration type or the differential type as the lapping sheet 21 depends on the condition of the construction site and various other conditions.

Since the permeable sheet has a property of allowing water to pass therethrough, the rainwater flowing into the storage structure 13 is gradually discharged to the outside of the storage structure 13, And serves as a buffer means to prevent flooding. That is, rainwater flowing into the storage structure 13 at the time of flooding is flowed to the underground to prevent flooding of the surrounding area.

The car-like sheet is a sheet which does not allow water to pass through, and the rainwater stored in the storage structure (13) is kept so that rainwater is kept as long as possible. By applying a car seats, another important function of the stormwater storage facility is to achieve reuse of rainwater. For reference, the storeroom 11, to which the car-like sheet is applied, is provided with a machine room 27 for pumping stored rainwater to the outside.

The lapping sheet 21 may be placed between the base 19 and the storage structure 13 in accordance with the circumstances. For example, when the base 19 is made of gravel or sand or a mixture thereof, the lapping sheet 21 can only be laid on the base 19.

Reference numeral 23 denotes a receiving member. The support member 23 serves to pass the rainwater that has entered the storage structure 13 through the manhole 25 to the side through the flow hole 23a. The shape and size of the support member 23, as well as the number and location of the installation, are designed to be different according to the situation of the site and the requirements.

On the other hand, the manhole 25 is a space disposed on the side of the storage structure 13, and receives rainwater therein during rainfall, and sends the received rainwater to the storage structure 13 through a connection pipe 25a. The manhole 25 itself may be attached to the reservoir structure 13 in some cases. That is, one side of the storage structure 13 may be emptied and the manhole 25 may be positioned in place.

The machine room 27 is a space reserved on the other side of the storage structure 13 and accommodates therein a pump 29, a drain pipe 33 and a control unit (not shown). The pump 29 serves to supply the rainwater W stored in the storage structure 13 to the outside through the drain pipe 33 under the control of the control unit.

FIG. 2 is a plan view showing an embodiment of the storage structure 13 applicable to the stormwater storage facility 11 of FIG. 1, and FIG. 3 is a plan view showing the construction of the storage structure 13 shown in FIG. Fig. 4 is an exploded perspective view showing a part of the storage structure 13. Fig.

Basically, the upright retention structure 13 for storable storage according to the present embodiment is constructed by directly connecting a plurality of extrusion-molded frames to each other through sliding coupling.

2, the storage structure 13 according to the present embodiment includes a plurality of central frames 35 directly connected to each other, a plurality of central frames 35 disposed on the outer frame of the central frame 35, 35 and the first, second and third side frames 37, 39, 41 which are directly connected to each other.

The center frame 35 includes three plate portions 35c extending at an angle of 120 degrees and a fitting portion 35a or a holder portion 35b formed at an end portion in the width direction of each plate portion 35c . The center frame 35 has two shapes, and one type of center frame has a fitting portion 35a, and the other type of central frame 35 has a holder portion 35b.

The fitting and fixing portion 35a is formed at a widthwise end of each plate portion 35c to be thicker than the thickness of the plate portion 35c. In this embodiment, for example, it takes the form of a round bar. Needless to say, the fitting and fixing part 35a is integrally formed with each plate part 35c. It is needless to say that the cross-sectional shape of the fitting and fixing part can be changed in any way.

The holder portion 35b is a portion for receiving and fixing the fitting and fixing portion 35a therein and provides a sliding groove 35d for receiving the fitting and fixing portion 35a. The holder 35b may be elastically deformable so that the fitting portion 35a can be elastically compressed.

In order to couple the central frames 35 having the above structure to each other, the fitting securing portion 35a of one frame should be inserted into the sliding groove 35d of the neighboring frame. To this end, the central frame 35 to be newly joined is lifted and the lower end of the holder 35b is aligned with the fitting and fixing part 35a of the mating frame 35 which is vertically waiting on the base 19, The raised center frame should be lowered vertically.

By fitting the holder 35b and the fitting portion 35a vertically, the central frame 35 lifted (by the operator) is lowered so that the fitting portion 35a ). The two frames are mutually coupled but directly connected to each other.

The fitting of the fitting portion 35a to the holder portion 35b can be applied in a press fitting manner and the adhesive can be applied and fixed between the holder portion 35b and the fitting portion 35a have.

3 shows an example in which the frame 35 in which the holder 35b is formed is directly connected to the lower portion 35a in alignment with the fitting portion 35a. Conversely, the frame 35 It is natural that the frame 35 having the fitting and fixing portion 35a should be lifted up and lowered in accordance with the holder portion 35b.

Meanwhile, the side frames include a first side frame 37, a second side frame 39, and a third side frame 41. The first, second and third side frames (37, 39, 41) are directly fixed to the outer frame of the central frame assembly through a sliding connection to provide a flat outer wall surface. In other words, the side of the storage structure 13 is closed to have a square outer wall.

6 shows the structure of the center frame 35 and the first, second and third side frames 37, 39 and 41 in more detail.

6A is a cross-sectional view showing one form of the center frame 35 described above. The holder 35b is applied to the center frame 35 shown in Fig. 6A. Unlike the holder portion 35b, the center frame to which the fitting portion 35a is applied has the same shape.

6A, the center frame 35 includes three plate portions 35c opened to have an angle of 120 degrees with respect to each other, and a plate portion 35c fitted inside the plate portion 35c to reinforce the structural strength And a reinforcing beam 35e. The reinforcing beam 35e may not be applied.

A holder portion 35b is provided at an end portion in the width direction of each plate portion 35c. The holder 35b has a sliding groove 35d for accommodating adjacent fitting and fixing portions 35a, 37a, 39a, and 41a. The width of the plate portion 35c is all the same.

6B is a first side frame 37. Fig. The first side frame 37 is formed by extrusion molding and has a predetermined cross section in the longitudinal direction.

The first side frame 37 is composed of two plate portions 37c having a certain thickness and width. That is, the first side frame 37 includes a plate portion 37c having a relatively large width and exposed to the outside of the storage structure 13, and a plate portion 37c having a relatively small width and being directly connected to the center frame 35 Part 37c. The plate portion having a small width is inclined so as to have an angle of 60 degrees on one side of the plate portion having a large width.

At the end of the plate portion 37c in the width direction, a fitting portion 37a and a holder portion 37b are provided. The fitting and fixing portion 37a has a sliding groove 37d for receiving the adjacent fitting and fixing portion as a portion that engages with the corresponding holder portion 37b.

 The holder 37b and the fitting and securing portion 37a are formed in a shape corresponding to the installation position of the first side frame 37 Are combined differently. In the first side frame 37, the number of the fitting-in portions 37a may be 0 to 3, and the number of the holder portions 37b may be 0 to 3.

A reinforcing beam 37e for reinforcing the rigidity may be further applied to the inside of the first side frame 37. [

The second side frame 39 shown in Fig. 6C has a plate portion 39c which is relatively wide and exposed to the outside of the storage structure 13, and a plate portion 39c which is relatively narrow in width and which is directly connected to the center frame 35 It consists of two plate parts. The narrow-width plate portion is inclined at an angle of 30 degrees to one side of the wide plate portion.

In addition, a fitting portion 39a and a holder portion 39b are integrally formed at the widthwise end portions of the respective plate portions 39c. The holder portion 39b has a sliding groove 39d for receiving and fixing the adjacent fitting and fixing portion.

The positions of the fitting and fixing part 39a and the holder part 39b are different according to the shape of the adjacent frame. For example, if the fitting portion is located on the opposite plate portion corresponding to the one plate portion 39c, the holder portion 39b is formed, and if the holder portion corresponds, the fitting portion 39a is positioned.

A reinforcing beam 39e for reinforcing the structural rigidity of the second side frame 39 may be applied to the second side frame 39 as well.

The third side frame 41 has the structure shown in Fig. 6D. That is, the third side frame 41 includes two plate portions 41c that are open at an angle of 90 degrees, and a plate portion 41c that is sandwiched between the plate portions and is inclined at an angle of 30 degrees with respect to one plate portion. (41c).

Needless to say, the third side frame 41 is also extrusion-molded. The third side frame (41) is located at four corners of the storage structure (13).

In addition, a fitting securing portion 41a or a holder portion 41b is formed at the widthwise end of each plate portion 41c. The holder portion 41b has a sliding groove 41d for receiving and fixing the fitting and fixing portion. The reinforcing beam 41e can also be applied to the third side frame 41 to reinforce the structural strength.

On the other hand, as shown in Fig. 2, the center frame 35 constitutes a central portion of the storage structure 13 by slidingly engaging the fitting securing portions 35a with the holder portions 35b. In particular, each central frame 35 has a structure directly connected to the neighboring central frame 35 and has a hexagonal honeycomb-like planar structure as a whole.

The first side frames 37 are joined to the center frame 35 in a state directly connected to each other to form both side walls of the storage structure 13. The engagement of the first side frame 37 with respect to the center frame 35 is achieved by sliding engagement of the fitting securing portion 37a with respect to the holder portion 35b or sliding engagement of the fitting portion 37a with respect to the holder portion 37b And is the sliding engagement of the fitting fixing portion 35a.

The second side frames 39 are also directly connected to the central frame 35 in direct contact with each other to provide the remaining two wall surfaces of the storage structure 13. [ The coupling of the second side frames 39 and the coupling of the second side frames 39 to the central frame are as described above.

The third side frame 41 is simultaneously engaged with the center frame 35, the first side frame 37 and the second side frame 39. That is, the one plate portion 41c is directly connected to the first side frame 37, the other plate portion is connected to the second side frame 39, and the central plate portion is directly connected to the center frame 35.

The planar shape of the storage structure 13 constructed through the direct coupling method can be formed to have a hexagonal honeycomb shape shown in FIG. 2 or a square checkerboard pattern shown in FIG. It is needless to say that polygonal patterns such as a triangle, a pentagon, a polygon, and an octagon can be implemented in any number of hexagons or rectangular shapes.

On the other hand, as shown in Fig. 4, a supporting member 23 is provided at a lower portion of some central frame 35. Fig. The supporting member 25 is a member having a flow hole 23a formed at a lower portion thereof and serves to pass rainwater while supporting the center frame 35. [ The presence of the support member 23 allows the rainwater flowing into the storage structure 13 to spread out throughout the storage structure 13. [ It is needless to say that the shape of the support member 23 can be changed in various ways as long as such a function can be achieved.

In the case of the support member 23 shown in Fig. 4, the support member 23 has an upper support groove 23b. The support groove 23b is a groove for receiving the lower end portion of the center frame 35. [ Further, a fitting protrusion 23c is formed on the side of the receiving member 23. The fitting protrusion 23c is a portion that fits in the holder portion 35b of the adjacent center frame 35. [

When the support member 23 supports the center frame 35 having the holder portion 35b, it is possible to replace the fitting protrusion 23c (which can accommodate the fitting and fixing portion 35a of the neighboring central frame) (Not shown).

5 is an exploded perspective view for explaining another example of the support member shown in FIG.

A mounting hole 35f is formed at the lower end of the center frame 35 and a supporting member 49 is attached to the mounting hole 35f in order to provide a flow port for passing rainwater through the center frame 35, .

The mounting hole 35f is a through-hole formed by a separate machining process on the lower end of the prepared central frame 35. [ The supporting member 49 is a member made to fit in the mounting hole 35f and is fitted and fixed in the mounting hole 35f.

The support member 49 can be manufactured, for example, by a plastic injection method, and has a flow hole 49b at a lower portion thereof. The flow hole (49b) functions as the flow hole (23a) of the receiving member (23).

FIG. 7 is a plan view showing another example of the storage structure 13 that can be applied to the storage facility shown in FIG. 1, and FIGS. 8A, 8B, 43 and the first and second side frames 45, 47, respectively.

A holder portion 43b or a fitting portion 43a is formed at an end portion of each plate portion 43c in the width direction. In FIG. 8A, only the holder 43b is shown, but with reference to FIG. 7, the fitting portion 43a is also formed. The holder portion 43b is provided with a sliding groove 43d for receiving and fixing the corresponding fitting portion 43a.

In addition, a reinforcing beam 43e may be added to the inner frame 43 in consideration of the structural strength of the center frame 43. The reinforcing beam 43e is a reinforcing member made of a metal plate in the same manner as other reinforcing beams and supports the center frame 43 so that it is not bent or twisted by an external force.

The first side frame 45 shown in Fig. 8B has a cross-sectional shape. That is, the second side frame 45 is formed such that two plate portions 45c having different widths are formed at right angles. It goes without saying that the fitting portion 45a and the holder portion 45b are provided at each end of each of the plate portions 45c. A sliding groove 45d is formed in the holder portion 45b to receive and fix the fitting portion 45a.

A reinforcing beam 45e may be applied to the inside of the first side frame 45 to reinforce the structural rigidity.

FIG. 9 is a block diagram showing a construction method of a stormwater storage facility according to an embodiment of the present invention.

As shown in the figure, the construction method of the stormwater storage facility according to the present embodiment starts with the tearing step 101. The tearing step 100 is a process of securing an underground space by excavating soil in an area into which the storm reservoir facility 11 is to be inserted. The depth and width of the above-mentioned underground space will obviously vary depending on the conditions and other needs of the area.

If the tearing step 101 is completed, a base mounting step 103 is performed. Basically, the base installation step 103 is a process of flattening the bottom surface of the underground space. The ground reinforcement process for reinforcing the ground in the base installation step 103 may be further performed. For example, if the bottom of the retention structure 13 is damp or fragile, dug more soil, fill sand or gravel, or pour the concrete to form a flat, hard bottom surface.

Following the base installation step (103), a storage structure construction step (105) is performed. The storage structure construction step 105 includes a fitting process 105a for constructing the storage structure 13 on the base 19 and a cover plate 17 disposed on the storage structure 13 And a step of winding the storage structure 13, the cover plate 17, and the base 19 with the lapping sheet 21. In some cases, only the storage structure 13 and the cover plate 17 may be wound.

The fitting process 105a is a process in which the frames 35, 37, 39, 41, 43, 45, 47 are directly mounted on the base 19 in a sliding manner with respect to each other.

If the storage structure building step 105 is completed, a manhole setting step 107 is performed. The manhole setting step 107 is a step of disposing a manhole 25 at an appropriate place on the side of the storage structure 13 and communicating with the storage structure 13 via the connection pipe 25a.

After completion of the above process, the subsequent soil step 109 is a process of covering the upper part of the storage structure 13 with soil. A sidewalk block, asphalt or concrete may be laid on top of the soil that is packed in the reservoir structure (13). The entire construction process is completed through the covering step (109).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
