The present invention relates to a slope support block using timber to form a slope support block using wood, each block to form a staggered coupling arrangement as a whole, to effectively support slope and to be environmentally friendly and easy to construct.

In general, the retaining wall refers to a structure that is installed to create land on the slope when constructing the structure, or to prevent soil leakage, which is the main cause of collapse in waterways or streams. Retaining wall blocks are widely used for masonry retaining wall construction used in construction, waterways and embankments.

Reinforced earth retaining walls are made in various forms by concrete, masonry, brick, and stone or concrete blocks. The anchor blocks are constructed horizontally and overlap each other in the vertical direction to form the reinforcement retaining wall. Since the anchor blocks constructed as described above cannot withstand the load acting from the soil on the rear side of the block only by the binding force between the blocks, a method of binding the block to the backfill reinforcement section is used.

One typical example of such an anchor block is shown in FIG. 1, and an example of a reinforced earth retaining wall construction using the anchor block is shown in plan view in FIG. 2.

As shown in FIG. 1, in general, the anchor block for reinforcing soil retaining wall construction is a unit in which the front portion 101 exposed to the outside and the rear portion 102 embedded in the soil are connected by a pair of connecting portions 103 and 103 ′. It is structured. Fixing grooves 104 are formed on the upper surface of the front portion 101, and connecting grooves 105 and 105 'are formed on the upper surfaces of the pair of connecting portions 103 and 103', respectively. Connection protrusions 106 and 106 'are formed on the lower surface of the connecting portions 103 and 103' to be connected to the connecting grooves 105 and 105 'of the block located at the bottom of the retaining wall. On the front surface of the lower surface of the connecting portions 103 and 103 ', locking jaws 107 and 107' are formed which are accommodated in the space between the connecting portions 103 and 103 'of the block located at the bottom when the retaining wall is constructed.

The anchor block as described above forms a retaining wall in which the upper blocks are alternately stacked on top of the lower blocks arranged in a row, which will be described in detail with reference to FIG. 2.

In the drawings, the lower blocks are referred to as DB, DB ', and the upper blocks as UB for convenience of description. As shown, the upper block UB is stacked on the upper portion of the plurality of lower blocks DB and DB 'arranged in a row so as to be positioned between neighboring lower blocks DB and DB'. At this time, one connecting protrusion 106 of the upper block UB is accommodated in the connecting groove 105 of the lower block DB, and the other connecting protrusion 106 'of the upper block UB is the lower block. It is accommodated in the connecting groove 105 'of DB'. Similarly, one of the engaging jaws 107 and 107 'of the upper block UB is between the connecting portions 103 and 103' of the lower block DB, and the other is between the connecting portions 103 and 103 'of the lower block DB'. It is located.

On the other hand, the geogrid 110 used as the block binding means has a pin (not shown) in the front end of the upper and lower blocks (UB, DB), more specifically in the fixing groove 104 of the lower block (DB) It is buried in the reinforcement soil section behind the block in a fixed state. The geogrid 110 binds the anchor blocks constructed up and down to the reinforcement soil section behind the block, thereby increasing the binding force between the blocks and preventing the block from being pushed or deformed by earth pressure.

However, in the conventional anchor block as described above, in the state in which the geogrid-shaped geogrid is fitted into the fixing groove, by making the connecting projection of the upper block is coupled to the connecting groove of the lower block and the locking jaws are fitted between the connecting portion, While increasing the number of maneuvers, there was a problem that the stability is lowered when the geogrid is deformed.

In particular, the conventional blocks are formed of concrete and have a large weight. In order to install heavy concrete blocks on slopes, heavy equipment is required, which causes a loss of workability. In addition, the concrete block has a problem that is not environmentally friendly, the concrete shrinks and expands as the temperature changes, causing cracking or cracking of the block.

In the lateral direction of one slope supporting block 10, the supporting blocks 10a are arranged such that the horizontal members are in contact with each other, and in the downward direction, the other slope supporting blocks 10b are arranged. At this time, it is preferable that the blocks arranged in the lower side are arranged so that the connection portions between the upper blocks are located in the horizontal center of the lower block. This is to provide an effect to distribute the load received by the slope and to form a more rigid slope support structure.

The present invention is environmentally friendly because each component of the slope support block is made of wood, which is much lighter than conventional concrete blocks. Therefore, not only the natural aesthetics by the slope support block, but also the effect of preventing pollution by concrete, promoting the vegetation composition. In addition, since it is light weight, it can be installed by manpower without using heavy equipment, and it provides the advantages of easy transportation of blocks. In addition, it is possible to prevent cracking or cracking due to temperature change by the self shrinking force of wood.

In addition, the present invention provides a structure in which horizontal and vertical members are connected to each other and the support members are secured to the slopes and arranged even if the relatively light materials are arranged to be bonded to each other, thereby ensuring sufficient slope support force as well as each block. There is an effect to increase the overall support by having them staggered to each other arrangement.
