Description

Retaining wall structure using wood

The present invention relates to a retaining wall structure using wood, and more particularly, to a retaining wall structure using wood that is environmentally friendly, safe and durable.

In general, a levee refers to a structure built high at the boundary where rivers, lakes, and seas separate from the land for the purpose of preventing floods by preventing water from overflowing out of the lake and facilitating communication of running water.

Among them, the embankment built in the river is usually filled with soil to form a bank along the river, and a revetment block is installed on the embanked slope to prevent the collapse of the embankment by preventing the outflow of the filled soil. have.

However, in the case of a small river valley located in a mountain valley, it is impossible to build a levee due to the geographical conditions. Therefore, landslides often occur due to scouring in the curve section where the flow of the ravine is lost or the flow of the rapids is changed due to the rapid increase in the flow rate during the rainy season.

To solve this problem, concrete retaining walls are sometimes installed in the valley section of small rivers where soil loss due to rapid currents and scouring are expected.

As an example of the technology for the retaining wall installed in such a valley section, Korean Patent No. 10-0657182 discloses a foundation block having a rectangular parallelepiped shape in the left and right width directions, and a foundation block having an inclined surface to form a river channel. A pair of auxiliary blocks that are fastened and fixed to each other, a plurality of tension bolts that connect the foundation block and the auxiliary block to other basic blocks and auxiliary blocks adjacent thereto at a predetermined distance and spaced apart from each other, and It is characterized in that it comprises a gabion retaining wall that is disposed between both sides of the assembled block to support the soil around the small river and at the same time protects the soil from being lost, and a filling stone that is filled on the river floor between the foundation block and the other foundation block. A small river valley soil loss prevention facility has been launched.

However, the conventional retaining wall installed in the small river valley section has a problem that, as a concrete retaining wall or a block structure is installed in a nature-friendly space called a waterside space, it spoils the natural beauty and brings a sense of disparity with the surrounding landscape.

Therefore, in order to solve this problem, conventionally, there are techniques to form an eco-friendly aesthetic by configuring a concrete block to be planted, but in this case, there is a problem that safety is not secured, such as the loss of planted plants due to an increase in water level. there was.

As shown in the connection wire 520, one end is fixed by a fixing unit 510 through the through hole 310 of the support part 300, and the other end is reinforced wood 201 of the wooden frame part 200. ) Is wound and connected to be fixed by a fixing clip 530.

At this time, the anchorage 510 may have various configurations such as a wedge-shaped anchorage that can be anchored to the concrete foundation portion 100.

The fixing clip 530 is configured to clamp the connection wire 520 by an operator's manipulation, and this configuration can be applied in various ways.

For example, although the fixing clip 530 is not shown, one side and the other side are each bent to form a ring shape, and one end and the other end may be formed of elastic clips that are elastically in close contact with each other.

When the user presses the end of the elastic clip, the other end is opened while being spaced apart and the side of the connection wire 520 is inserted into the inner side, and then, when the user releases the hand, it is restored again so that one end and the other end are The inner connection wire 520 is configured to be bound while being in close contact with each other.

Alternatively, the fixing clip 530 is composed of one of the above-described clip bodies, and in addition to the configuration in which one end and the other end are elastically adhered to each other, the bent clip body and one end are hinged to one end of the clip body, and the other The end includes a hook body that is in close contact with the other end of the clip body, and an elastic member that is coupled to the hook body to elastically support the hook body to be in elastic contact with the clip body so that the hook body rotates according to the user's manipulation. A variety of configurations can be applied, such as can be applied.

The configuration of the connection wire 520 may be applied to a known fixing wire used in construction by combining a fixing tool and a clip at each end.

On the other hand, the connection wire 520 is connected only to any one of the reinforced wood 201 constituting the wooden frame part 200 according to the securing of the support force of the wooden frame part 200 and the field situation, or stacked adjacent to each other. A plurality of reinforcing wood 201 can be connected in various ways, such as being able to wind and connect at the same time.

Further, the connection wire 520 is preferably fixed and fixed in the through hole 310 having a height lower than the fixing height of the fixing clip 530 connected to the wooden frame part 200.

This is, when the wooden frame part 200 and the support part 300 are bound to each other, the other end connected to the wooden frame part 200 is located above one end fixed to the support part 300, so that the connection wire 520 is It is to prevent lifting of the wooden frame part 200 and to support it more stably by exerting a tensile force to pull the wooden frame part 200 downward.

The connection wire 520 may be configured in a plurality as shown to stably support the entire wooden frame part 200, and can be connected and fixed with respect to each side of the wooden frame part 200 in various directions and positions. .

Referring to FIG. 6, the retaining wall structure includes a foundation fastening unit 600 that connects the concrete foundation 100 and the wooden frame 200 to each other.

The foundation fastening unit 600, one end is coupled to the concrete foundation portion 100, the other end is coupled to the wooden frame portion 200, so that the wooden frame portion 200 is supported by the concrete foundation portion 100.

The basic fastening unit 600 is configured to include a cable 611, a fastener 612, and a fixing wire 640.

The cable 611 is configured such that one end of the concrete foundation 100 is fixed, and the other end of the concrete foundation 100 is exposed to the outside. At this time, the cable 611 is configured such that one end is fixed to the reinforcing bar 120 of the concrete base portion 100, it is preferable to secure a supporting force.

The fastener 612 is provided at the other end of the cable 611 to be connected to the fixing wire 640, and may be configured as a fastening ring 613 as shown.

The fixing wire 640 is provided with a fastening clip 620 so that one end is connected to the fastening ring 613, and the other end is provided with a fixing clip 630 so as to be fixed by winding reinforced wood 201. Accordingly, the fixing wire 640, one end is fixed to the concrete base portion 100 and the other end is fixed by the fixing clip 530 by winding and connecting the reinforcing wood 201 of the wooden frame portion 200.

Here, since the configuration of the fixing clip 630 and the fastening clip 620 is substantially the same as the configuration of the fixing clip 630 coupled to the above-described connection wire 520, a detailed description thereof will be omitted.

On the other hand, the retaining wall structure, by simultaneously configuring the support fastening unit 500 and the foundation fastening unit 600 according to the shape of the wooden frame part 200 and the construction site situation, it is also possible to secure the support force of the wooden frame part 200 have.

In this case, the retaining wall structure includes the wooden frame part 200 corresponding to the upper position of the support part 300 based on the height of the support part 300 so that the wooden frame part 200 is supported through the support fastening unit 500. It is preferable that the wooden frame part 200 corresponding to the lower position of the support part 300 is supported so that the wooden frame part 200 is supported through the base fastening unit 600.
