Description

Retaining wall structure using wood}

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

In general, a dike is a structure that is built up high on the boundary that separates rivers, lakes, and seas from land for the purpose of preventing flooding or saving water by preventing water from flowing out of the lake and facilitating communication with running water.

Among them, embankments built in rivers usually emit earth and sand to form embankments along the river, and to prevent the collapse of embankment by preventing the outflow of embankment, a bank is installed on the embankment to protect the slope. have.

However, in the case of a small river valley located in a valley, it is impossible to build an embankment due to geographical conditions. For this reason, landslides are often caused by scouring in the curve section where the sediment around the valley is lost or the rapid flow is diverted due to the rapidly flowing runoff during the rainy season.

In order to solve this, concrete retaining walls, etc. are sometimes installed in the valleys of small rivers where it is expected to be excavated due to rapids and scour.

As an example of a technique for a retaining wall installed in such a valley section, Korean Patent Registration No. 10-0657182 discloses a long rectangular parallelepiped base block in the left and right width directions, and an inclined surface in order to form a river channel. A pair of opposing blocks that are fastened and fixed, and a plurality of tension bolts that connect the base block and the auxiliary block to other basic blocks and auxiliary blocks spaced apart from each other by a predetermined distance, and the assembled block are different from It is arranged between both sides of the assembled block and supports the soil around the small river, and at the same time, it comprises a gabion retaining wall that protects the soil from being lost, and a filling stone filled on the river bottom between the foundation block and other foundation blocks. A small river valley prevention facility has been disclosed.

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

In order to solve this, conventionally, there are some technologies to construct a concrete block so that it can be planted to form an environmentally friendly aesthetic, but in this case, there is a problem that safety is not secured such as loss of plant plants due to rising water level. there was.

Republic of Korea Registered Patent No. 10-0657182

An object of the present invention is to provide a retaining wall structure using wood, which not only maintains a natural-friendly aesthetic of the waterside space, but also can stably support a slope even when the water level rises, using wood, which is an eco-friendly member.

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

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

The elastic clip, when the user presses the end of the elastic clip, the other end is spaced apart and opened to allow the side of the connecting wire 520 to be inserted inward, and then restored when the user releases the hand, and the one end and the other end The connection wire 520 of the inner side is configured to be tightly closed while being tightly closed.

Alternatively, the fixing clip 530 is composed of the above-described one clip body, and in addition to the configuration in which one end and the other end are elastically in close contact, the bent clip body and one end are hinged to one end of the clip body and other The end portion comprises a hook body that is in close contact with the other end of the clip body, and an elastic member coupled to the hook body to elastically support the hook body to be elastically in close contact with the clip body, thereby allowing the hook body to rotate according to the user's operation. Various configurations such as can be applied.

In the configuration of the connection wire 520, a fixing fixture and a clip are combined at each end, and a known fixing wire used in construction may be applied.

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

Further, the connection wire 520, it is preferable that the fixing hole 510 is fixed to the through-hole 310 having a height lower than the fixing height of the fixing clip 530 connected to the wooden frame 200.

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

The connecting wire 520 is composed of a plurality of parts as shown to stably support the entire wooden frame 200, and can be fixed in various directions and positions with respect to each side of the wooden frame 200. .

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

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

The basic fastening unit 600 includes a cable 611, a fastener 612, and a fixing wire 640.

The cable 611, one end is fixed to the concrete foundation 100, the other end is configured to be exposed to the outside of the concrete foundation (100). At this time, the cable 611, one end is preferably configured to be fixed to the reinforcing bar 120 of the concrete base portion 100, to secure the support.

The fastener 612 is provided at the other end of the cable 611 to be connected to the fixed 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 fastening clip 630 to be fixed by winding the reinforcement wood 201. Accordingly, the fixing wire 640, one end is fixed to the concrete base portion 100 and the other end is fixed by a fixing clip 530 by winding and connecting the reinforcing wood 201 of the wooden frame 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, detailed description thereof will be omitted.

Meanwhile, the retaining wall structure may simultaneously configure the support fastening unit 500 and the basic fastening unit 600 according to the shape of the wooden frame 200 and the construction site situation, thereby securing the supporting force of the wooden frame 200. have.

In this case, the retaining wall structure, the wooden frame part 200 corresponding to the upper position of the support part 300 based on the height of the support part 300 is such that the wooden frame part 200 is supported through the support fastening unit 500 , The wooden frame part 200 corresponding to the lower position of the support part 300 is preferably such that the wooden frame part 200 is supported through the basic fastening unit 600.

This, by effectively using the support fastening unit 500 and the base fastening unit 600 for supporting the wooden frame 200, it is possible to avoid the interference of the connecting wire 520 and the fixed wire 640, and In addition, it is possible to obtain a more economical effect by reducing the length of wire use.

According to the above, the retaining wall structure constitutes a support part 300 so that the wooden frame part 200 can be stably supported even when the water level rises, and the support fastening unit 500 and the basic fastening unit 600 are provided.
