Description

Block type retaining wall {Block type retaining wall}

The present invention relates to a block-type reinforced soil retaining wall, and more particularly, to a block-type retaining wall made so that the slopes generated by cutting the soil or accumulating soil do not collapse under the pressure of the soil.

Reinforced earth retaining walls can be constructed in various forms and methods by concrete, masonry, brick, and blocks made of stone or concrete, where the blocks are constructed horizontally and superimposed on one another in order to construct the reinforced earth retaining walls.

A block and a structure thereof for use in constructing a reinforced earth retaining wall are disclosed in Korean Patent No. 116843 (designated name: wall block and wall structure).

As shown in FIG. 1, a conventional reinforced earth retaining wall construction block extends rearward from both ends of the front surface 1, the upper surface 2, the lower surface 3 and the front surface 1 having opposing ends. It has a block body (5) comprising side (4) 4 '.

In addition, the reinforcement soil retaining wall building block is opened in any one of the upper surface (2) and the lower surface (3) of the block body (5) and an arc shape (arc curved curved hole) spaced apart from the side surface (4) (4 '). Upper and lower block interconnection means having first and second pockets 6, 6 'and first and second pin holes 8, 8' for receiving the pins 7).

The first pinhole 8 is arranged adjacent to the first pocket 6 and is arranged laterally shifted therefrom, and the second pinhole 8 'is adjacent to the second pocket 6'. And arranged laterally from here.

Here, the first and second pockets 6 and 6 'are formed to open to the upper surface 2 of the block body 5, and the first and second pin holes 8 and 8' are made to block. It is formed to penetrate the body 5 up and down.

The lower end of the pin 7 protrudes downward from the block body 5 through the pin holes 8 and 8 '.

In the conventional block configured as described above, a plurality of blocks are constructed in a shape as shown in FIG. 2 to build the retaining wall, and the pins inserted into the pin holes 8 and 8 'of the upper block UB are the lower block DB. The coupling position of the upper and lower blocks UB (DB) is determined by being inserted into the pockets 6 and 6 'of the upper part, and at this time, the pin 7 moves upwards within the range of the pockets 6 and 6'. The coupling position of the block UB with respect to the lower block DB may be changed.

Accordingly, the conventional block provides an advantage that the retaining wall can be constructed by various construction methods in consideration of landscaping applications such as straight lines, concave and blocked curves, serpentine shapes, and circular shapes.

For example, as shown in FIG. 3A, the upper block UB continues to contact the pin 7 of the upper block UB with the front end of the pockets 6 and 6 ′ of the lower block DB. By stacking, it is possible to construct a retaining wall in the form of an upright structure.

As shown in FIG. 3B, when the pin 7 of the upper block UB is continuously stacked on the upper block UB so as to contact the rear end of the pockets 6 and 6 ′ of the lower block DB, the upper block UB is continuously stacked. Since the upper block UB is retracted and constructed as much as the length of the front and rear directions of the pockets 6 and 6 ', the stepped retraction is possible.

However, since the shape of the pockets 6 and 6 'is formed in the forward and backward directions of the block in the form of an arc-shaped curved hole, the conventional reinforcement soil retaining wall construction block as described above is the pocket 6 and 6'. The pin 7 inserted in can flow back and forth in the pockets 6 and 6 '.

In order to prevent the flow of the pins and the movement of the block, the shape of the pin and the shape of the pocket for accommodating the pins are specified in advance, and according to the situation, the inclination angle of the retaining wall cannot be arbitrarily selected, In order to build the retaining wall, there was a problem of separately manufacturing the pin and the block according to the inclination angle.

In addition, the retaining wall constructed by the conventional block has a state in which the pin 7 of the upper block UB is in contact with the wall surface of the pockets 6 and 6 'in the form of an arc-shaped curved hole of the lower block DB. The load by earth pressure is supported, but because the contact area is very small, the concentrated stress acts on the pin 7, and accordingly the wall surface of the pocket 6, 6 ′ in contact with the pin 7, etc. Problems may arise in terms of safety, such as cracks from.

In addition, since the coupling between adjacent blocks and blocks and the firm coupling between the lower block (DB) and the upper block (UB) cannot be maintained, a problem arises between the block and the block due to earth pressure of the backfilled reinforcement soil, resulting in a risk of collapse. Will always follow.

The present invention is devised to solve the above problems, the object of the present invention is to prevent the flow of the retaining clip and the movement of the retaining wall block using the retaining wall block and the coupling clip, according to the coupling direction of the retaining wall block and the coupling clip It is to provide a block-reinforced earth retaining wall for building retaining walls by selecting an upright construction or a stepped retreat construction.

Another object of the present invention is to minimize the risk of collapse of the retaining wall by strengthening the connection of the adjacent retaining wall block and the retaining wall block and the coupling between the lower retaining wall block and the upper retaining wall block, and increase the cross-sectional area of the head of the coupling clip in the mounting groove. It is to provide a block-type reinforced earth retaining wall that can be distributed by the stress to prevent the occurrence of cracks.

In order to achieve the above object, the present invention provides a block type reinforced soil retaining wall constructed by stacking retaining wall blocks alternately with each other:

The retaining wall block has a pin receiving portion formed vertically on both sides of the upper and lower surfaces, and the coupling clip connecting the retaining wall block in the horizontal direction comprises a pin portion in both sides and a horizontal connection portion connecting the pin portion in an H shape. Done,

A portion of the pin is inserted into each of the left and right pin receiving portions of the adjacent lower retaining wall block to connect adjacent retaining wall blocks, and the upper retaining wall block is stacked alternately with the lower retaining wall block to the upper portion of the lower retaining wall block. To provide a block-type reinforced earth retaining wall, characterized in that the remaining portion of the pin portion is inserted into the pin receiving portion of the upper retaining wall block.
