Description

Supporting structure using decorative stone and method for construction thereof

The present invention relates to a support structure using decorative stones and a construction method thereof, and more specifically, to a support structure using decorative stones and a construction method thereof, which can ensure stability even during rainy seasons by strengthening a perforated rear support to resist back soil pressure and facilitating drainage through the perforated rear support.

Generally, countermeasure methods to prevent slope failures of river embankments, roads, apartment complexes, and other slopes can be divided into two types: safety factor maintenance methods and safety factor increase methods. Specifically, passive countermeasure methods protect slopes from direct factors that can cause slope failure by preventing the reduction in the slope safety factor due to water influences such as rainfall and snowmelt. Active countermeasure methods, on the other hand, attempt to improve the potential vulnerability of slopes deemed unsafe by increasing the safety factor of slopes using the resistance of retaining walls and other means.

Among them, a retaining wall, which is one of the safety factor increasing methods, is a wall that is formed to prevent collapse due to earth pressure or rain, etc., and is constructed with bricks or concrete, and is usually constructed by building blocks manufactured with concrete at a factory on the slope to stabilize the slope.

However, these retaining walls constructed with concrete blocks have the problem of obstructing the natural landscape and creating a sense of alienation because they are artificial structures, and they not only make the viewer feel oppressed, but also create a conflicting environment that does not fit in with the surrounding environment.

In addition, due to its nature, it lacks flexibility and variability in response to the shape of the slope or rock to be installed, so it is formed relatively far away from the slope or rock to be installed in order to secure a support base.

Therefore, there is a problem that a lot of work space is required, and the backfilling work after construction is relatively more, which extends the construction period and increases the construction cost. In addition, there is a problem that partial repairs are difficult in the event of partial damage to the retaining wall in the future.

In addition, the main cause of recent retaining wall collapse accidents is the increase in water pressure caused by rainwater during the rainy season. As the number of localized heavy rains has been increasing recently, it is necessary to respond to this.

In this regard, the patent 10-0933660 previously registered by the applicant discloses a technology for installing a horizontal fixture constructed in the form of a concrete beam at the rear end of a decorative stone and a vertical fixture constructed in the form of a concrete pillar, and then connecting the decorative stone and the horizontal fixture by a tension member.

This was proposed to collect and drain rainwater that flows into the ground and prevent the collapse of the ground due to water pressure, but there is a problem in that the gap between the horizontal and vertical fixtures is exposed without protection, so if the soil at the rear collapses, it cannot be reliably blocked, and there is a concern that the decorative stones may collapse.

The support structure of the present invention utilizes decorative stones and can be configured to include foundation concrete (100), individual decorative stones (200), a hardening agent mixture (300), a rear support drainage section (400), a first backfill soil layer (500), a second backfill soil layer (600), a vertical connecting tie (700), and a spacing member (800).

The base concrete (100) is used to firmly erect and construct the decorative stone (200), and can be divided into a first-stage concrete (110) and a second-stage concrete (120) that is poured on the upper surface of the first-stage concrete (110) and supports the lower part of the decorative stone (200).

In the first stage concrete (110), foundation reinforcement (111) is placed inside, and foundation reinforcement (112) is formed by bending upward at one end of the foundation reinforcement (111), and a part of the foundation reinforcement (112) penetrates the second stage concrete (120) and is exposed upward.

Decorative stones (200) and decorative stones (200) that are in contact with each other are joined to each other in close contact by means of a connecting member (220), and a support connecting member (240) is firmly connected and supported between a set anchor (210) provided on the decorative stones (200) and a foundation reinforcing bar (112). In addition, the gap formed between the decorative stones (200) and the decorative stones (200) is blocked with a non-woven fabric (230) to prevent soil from flowing out.

The solidifying agent mixture (300) is a mixture of a solidifying agent and the soil of the original ground that is hardened to improve bearing capacity. It is laid on one side of the upper surface of the foundation concrete (100) with a predetermined width and height so as to be spaced apart from the back of the decorative stone (200) by a predetermined distance, and is then compacted with a tamping machine. The solidifying agent mixture (300) is provided in multiple stages toward the upper side, and it is preferable that it be laid so as to gradually move away from the decorative stone (200) as it goes toward the upper side.

Here, the first hardening agent mixture (300) built on the upper surface of the foundation concrete (100) forms a lower support mixture (301) that extends to the space between the rear surface of the foundation concrete (100) and the inclined soil slope (130).

In addition, a concave-shaped hooking groove (310) is formed on the upper part of the solidifying agent mixture (300), and a fitting projection (320) that is fitted into the hooking groove (310) is formed protruding on the lower part of the solidifying agent mixture (300).

It is desirable that the catch groove (310) and the catch projection (320) be formed in a shape in which the width gradually increases toward the bottom so that they are firmly fitted together.

The rear support drainage unit (400) is provided in a horizontal state so as to be in contact with the rear end of the solidification agent mixture (300). The rear support drainage unit (400) is provided with a rainwater drainage pipe (410) in the longitudinal direction therein, and a rainwater inlet pipe (420) is formed to be drawn out on the upper surface of the rear support drainage unit (400) so as to be in communication with the rainwater drainage pipe (410), and a rainwater discharge pipe (430) that is in communication with the rainwater drainage pipe (410) is connected to the side of the rear support drainage unit (400), and the rainwater discharge pipe (430) can be formed to a length that is in contact with the decorative stone (200).

In addition, a non-woven fabric (230) is covered on the upper side of the rear support drainage unit (400), aggregate (450) is laminated on top of the non-woven fabric (230), and the upper side of the aggregate (450) is also covered with a non-woven fabric (230), so that rainwater discharged from the inclined soil slope (130) flows into the rainwater inlet pipe (420) of the rear support drainage unit (400), while blocking the inflow of soil.

The first backfill soil layer (500) is filled between the decorative stone (200) and the solidifying agent mixture (300), and the second backfill soil layer (600) is filled between the solidifying agent mixture (300) and the slope soil surface (130). In addition, non-woven fabrics (230) are additionally installed between the first backfill soil layers (500) at the upper and lower ends and between the second backfill soil layers (600) at the upper and lower ends, respectively.

At this time, crushed stone (510) is filled between the lower part of the first backfill soil layer (500) at the lowest level and the upper surface of the foundation concrete (100), and a perforated pipe (520) is installed longitudinally between the crushed stone (510) so that oxygen is supplied to the soil in normal times and rainwater can be discharged through the perforated pipe (520) formed with a slope to one side when it rains. It is also preferable to block the space between the crushed stone (510) and the first backfill soil layer (500) by covering it with a nonwoven fabric (230).

A vertical connecting tie (700) is further installed through the interior of the uppermost solidifying agent mixture (300) formed by multi-layering, starting from the lowest solidifying agent mixture (300), so that the solidifying agent mixture can be hardened as a whole. The vertical connecting tie (700) is intended to enable the pressure applied from the inclined soil slope (130) to be resisted simultaneously by the entire upper and lower solidifying agent mixture (300).

The spacing member (800) is connected between the decorative stone (200) and the rear support drainage unit (400) to prevent the decorative stone (200) from falling over or being pushed backward. To this end, a reinforcing bar (460) is arranged inside the rear support drainage unit (400), and a portion of the reinforcing bar (460) is exposed to the outside of the rear support drainage unit (400), and the spacing member (800) is connected between the reinforcing bar (460) and the set anchor (210) installed on the decorative stone (200).

Meanwhile, a vertical bar (900) may be installed so as to be in contact with the upper surface of the foundation concrete (100) to the tip of the uppermost rear support drainage unit (400), and the vertical bars (900) may be installed at predetermined intervals. To this end, a vertical bar connection socket (910) is installed on the upper surface of the foundation concrete (100), and the vertical bar (900) is installed by being fitted into a vertical bar connection groove (911) formed in the vertical bar connection socket (910). At this time, as the rear support drainage unit (400) is constructed to gradually move away from the decorative stone (200) toward the upper surface, it is preferable that the vertical bar (900) is also installed so as to be inclined parallel to the sloped soil surface (130).

In the case where the height of the inclined soil slope (130) of the support structure of the present invention is significantly higher than the height of the decorative stone (200), the decorative stone (200) may be constructed in two stages. To this end, a foundation concrete (100) is constructed again on the upper side of the decorative stone (200) of the first stage, and a second stage of decorative stone (200) is erected thereon, and a solidified soil mixture (300), a rear support drainage part (400), a first backfill soil layer (500), a second backfill soil layer (600), a vertical connection tie band (700), and a gap maintenance band (800) may be constructed.

Hereinafter, a method for constructing a support structure of the present invention configured as described above will be described.

In order to construct the support structure of the present invention, a excavation is made to a predetermined width and depth so as to be in contact with the lower part of the inclined soil slope (130) (S100).

And when pouring foundation concrete (100) into the excavated space (S110), it is preferable to pour the foundation concrete (100) divided into first-stage concrete (110) and second-stage concrete (120). To this end, first, foundation reinforcing bars (111) are arranged in the excavated space, and foundation reinforcing bars (112) are vertically erected and joined to one end of the foundation reinforcing bars (111), and then a formwork is installed and concrete is poured to form the first-stage concrete (110). The foundation reinforcing bars (112) are poured with a portion exposed on the upper surface of the first-stage concrete (110).

After installing a formwork again on the upper surface of the hardened first-stage concrete (110), the second-stage concrete (120) is poured to a predetermined height and allowed to harden. At this time, before pouring the second-stage concrete (120), a decorative stone (200) is erected and installed on the upper end of the first-stage concrete (110) and the second-stage concrete (120) is poured to a predetermined height, thereby constructing the structure with a portion of the lower part of the decorative stone (200) embedded in the second-stage concrete (120) (S120).

A set anchor (210) is embedded in a decorative stone (200), and a support connecting member (220) is connected between the set anchor (210) and the foundation reinforcing bar (112) to support the decorative stone (200). In addition, the surfaces of the set anchor (210) and the support connecting member (220) are epoxy coated to prevent corrosion. The decorative stones (200) and the decorative stones (200) that come into contact with each other are firmly connected to each other by the connecting member (220).

Accordingly, the lower part of the foundation concrete (100) is partially buried in the two-stage concrete (120) and the rear part is connected and supported by the foundation reinforcing steel pole (112) and the support connecting member (220), so there is no concern that the decorative stone (200) erected on the foundation concrete (100) will fall over during construction.

On the upper surface of the foundation concrete (100), vertical bars (900) can be further installed at predetermined intervals. To this end, a vertical bar connection socket (910) is firmly installed on the upper surface of the foundation concrete (100), and a vertical bar is inserted into a vertical bar connection groove (911) of the vertical bar connection socket (910) and erected. It is preferable that the vertical bar connection groove (911) be formed to be inclined so that the vertical bar (900) can be erected at an angle similar to the inclined soil slope (130) rather than being erected completely vertically.

A solidifying agent mixture (300) made by mixing a solidifying agent and soil is laid at a predetermined width and height so as to be spaced apart from the back of the decorative stone (200) at a predetermined interval (S130).

The hardening agent mixture (300) built on the upper surface of the foundation concrete (100) extends to the space between the rear surface of the foundation concrete (100) and the inclined soil slope (130) to form a lower support mixture (301).

When the solidified mixture soil (300) at the bottom is firmly hardened, a rear support drainage unit (400) is installed horizontally on the rear side of the solidified mixture soil (300) (S140). The rear support drainage unit (400) is supported by the solidified solidified mixture soil (300) and not only supports the decorative stone (200), but also serves to drain rainwater that has infiltrated the inclined soil slope (130).

To this end, the decorative stone (130) and the rear support drain (400) are connected to a gap maintainer (800) to maintain the gap, and multiple gap maintainers (800) can be connected (S150).

And, a rainwater discharge pipe (430) is connected to a rainwater induction pipe (410) of a rear support drainage unit (400) so that it is drawn out to the decorative stone (200), a non-woven fabric (230) is covered on the upper side of the rear support drainage unit (400), aggregate (450) is laminated on top of the non-woven fabric (230), and then the non-woven fabric (230) is covered again.

Here, it is desirable to manufacture the rear support drainage unit (400) in large quantities in a separate space and then transport and install it.

Afterwards, the first backfill soil layer (500) is formed by filling and compacting soil between the decorative stone (200) and the solidified mixed soil (300), and the second backfill soil layer (600) is formed by filling and compacting soil between the solidified mixed soil (300) and the inclined soil slope (130) (S160).

Here, it is preferable to construct the solidified mixed soil (300) and the first backfill soil layer (500) and the second backfill soil layer (600) by repeatedly forming them solidly through hardening and compaction from the bottom to a predetermined height, and then constructing them on top of that, thereby stacking them in multiple stages. In particular, it is preferable to form the solidified mixed soil (300) so that the distance between it and the decorative stone (200) gradually increases toward the upper end, like the slope of the inclined soil slope (130). Similarly, the first backfill soil layer (600) laid between the decorative stone (200) and the solidified mixed soil (300) also gradually increases in width toward the upper end.

Meanwhile, a concave-shaped catch groove (310) is formed on the upper surface of the solidification mixture (300) at the lowest level and hardened, and the solidification mixture (300) built on the upper side is partially inserted into the catch groove (310) to build it to a predetermined height, so that a catch protrusion (320) is connected and formed at the lower side. In addition, a concave-shaped catch groove (310) is formed at the upper side. In this way, a catch groove (310) is formed at the upper side of each solidification mixture (300) and a catch protrusion (320) is formed at the lower side so that they are fitted together.

As the solidified mixed soil (300) constructed in this way in multiple upper and lower stages is constructed with the upper and lower stages firmly fitted together, there is less concern about the solidified mixed soil (300) being pushed when the earth pressure of the inclined soil slope (130) is applied, and there is less concern about the decorative stone (200) being toppled.

In addition, a vertical connecting tie (700) that connects from the inside of the solidified soil mixture (300) at the lowest level to the inside of the solidified soil mixture (300) at the highest level can be installed by burying it.

Meanwhile, the first backfill soil layer (500) at the bottom is not backfilled with soil alone, but is partially filled with crushed stone (410), a perforated pipe (520) is installed, and the outside is wrapped with non-woven fabric (230), and then soil is backfilled and compacted on the outside to form the first backfill soil layer (500).

Accordingly, the support structure of the present invention using decorative stones has a structure in which, unlike the previous application, the solidified mixed soil (300) laminated in multiple stages blocks the entire area between the inclined soil slope (120) and the decorative stones (200). Accordingly, the solidified mixed soil (300) acts as a buffer wall to resist and buffer the earth pressure of the inclined soil slope (130) and prevent the soil from being lost. In addition, the solidified mixed soil (300) and the first backfilled soil layer (500) serve as a buffer so that the pressure applied from the inclined soil slope (130) is not applied to the decorative stones (130).

In the present invention, when there is a lot of rain, rainwater that has penetrated into the slope (130) is discharged and flows into the aggregate (450) through the upper non-woven fabric (230) of the rear support drainage unit (400), and this is again collected into the rainwater guide pipe (410) inside the rear support drainage unit (400) through the rainwater inlet pipe (42).

And again, it is discharged to the back of the decorative stone (200) through the excellent discharge pipe (430) on the side, and is discharged through the perforated pipe (520) provided on the side of the first backfill soil layer (500) at the lowest part, thereby having the effect of preventing the collapse of the soil.
