Description

Retaining wall block with split point {Block for retaining wall having split point}

The present invention relates to a retaining wall block used for constructing a sidewall of a dike, breakwater, or road, and more particularly, a retaining wall that can be used for both vertical and retracting constructions and, if necessary, can be split on the job site to an appropriate size. It's about blocks.

In general, soils formed on embankments, breakwaters or roadside walls are easily sheared or easily deformed by external pressure. Thus, the retaining wall structure is constructed using blocks made of stone or concrete on the side walls of the embankment or the like to prevent the embankment or the road side wall from being deformed or collapsed by earth pressure.

Such a retaining wall structure has a reinforced soil retaining wall method, such as gravity or anchor type construction.

In the case of the reinforced soil retaining wall method, the soil is formed only by the reinforcing action of the reinforcing fiber, but all the earth pressure is received by the reinforcing fiber, and the reinforcing fiber cost occupies most of the construction cost, and the retaining wall block has a structural dynamic function. There is a limit that can not be.

In the case of gravity type, the size of the retaining wall block is used to constrain the block and the reinforcing fiber by its own weight.

In addition, in the case of the anchor type, the retaining wall block is formed using the retaining wall block on which the anchor type projection is formed, and the adjacent retaining wall block is connected to each other. There is no limit.

In addition, when constructing using the retaining wall block, a retaining wall block having various sizes is required according to the height of the building. For example, if the height is about 1m, only the medium retaining wall block is stacked.If the height is about 3m, the retaining wall block is 1m at the bottom, the middle retaining wall is 1m. Small retaining wall blocks can be constructed by barking the finish.

However, in the case of the conventional retaining wall blocks, the retaining wall blocks cannot be split or cut to the desired size on the job site, so the retaining wall blocks of various sizes are produced in advance, or stacked only regardless of the height of the construction by using only one of the largest retaining wall blocks stacked at the bottom. There was a serious problem wasted waste of retaining wall blocks.

The technical problem to be achieved by the present invention is to use a single retaining wall block of the same type, retreat construction and vertical construction can be done at the same time, and also to separate one retaining wall block into the required size at the work site and use it as several retaining wall blocks. It is possible to provide a retaining wall block.

In order to achieve the above technical problem, the present invention is an upper surface formed with a convex portion and a recess; And a lower surface having a lower surface first recessed portion into which the upper surface convex portion is inserted and a lower surface second recessed portion formed to face the upper recessed portion.

Therefore, the retaining wall block according to the present invention has a matching portion coupled to each other when the retaining wall is constructed by the convex portion of the upper surface and the lower surface, and at the same time, the recess portion of the upper surface and the recess portion of the upper surface facing each other can split the retaining wall block as necessary. It is characterized by being a split point.

In the retaining wall block according to the present invention as described above, four upper surface convex portions are formed, and the upper concave portion may be formed between the upper convex portions, and three may be provided. It is preferably formed at the quarter point, the two quarter point and the three quarter point. In other words, such retaining wall blocks may be formed at a maximum of four retaining wall blocks by forming the aforementioned split points at 1/4, 2/4, and 3/4 points. One can be formed to act as a retaining wall block individually.

In addition, in the retaining wall block according to the present invention as described above, the lower surface first groove portion is formed directly below the upper surface concave portion of the lower surface of the first groove portion; And a lower parallel parallel first recessed portion formed parallel to the first lower recessed portion directly below the lower surface, and side through holes are formed below each of the upper convex portions. When the retaining wall block described herein is divided into a retaining wall block and formed into a small retaining wall block, the small retaining wall block also has at least two recesses formed on the lower surface thereof so that both vertical and retracting structures can be formed. Used in the vertical construction, the groove is spaced apart from it is to be combined with the convex portion during the retraction construction.

In addition, by forming the side through-holes in the retaining wall block according to the present invention it is possible to guide the flow of water to the side and in case of emergency can also support the retaining wall surrounding the wire in the through-holes of the retaining wall block. In addition, the side through-holes in the underwater part of the river retaining wall can be used as a fish house, contributing to the conservation of the river ecosystem.

Hereinafter, the retaining wall block will be described with reference to the accompanying drawings as an embodiment according to the present invention.

1 is a perspective view showing a retaining wall block as an embodiment according to the present invention, Figure 2 is a side view of the retaining wall block shown in FIG.

Referring to FIGS. 1 and 2, the retaining wall block 100 according to the present invention includes a front portion 110, an upper portion 120 having a convex portion 121, and a recess portion 122, a recess portion 131, 131a. , 131b and 132 are formed of a unit of concrete having a bottom portion 130, a rear portion 140 facing the front portion 110 and a side portion 150 formed with a through hole 151.

Although the front part 110 is illustrated as having a smooth surface without any pattern, the front surface 110 may have various shapes such as a stripe shape, a sawtooth shape, and a crushed surface. In addition, since the rear part 140 is not an exposed part, a special shape is not engraved on the surface. That is, in the retaining wall block 100 according to the present invention, the front portion 110 and the rear portion 140 is made without any difference from the known retaining wall blocks.

The upper surface portion 120 has four convex portions 121 and three concave portions 122, and the convex portions 121 are combined with concave portions formed on the lower surface to form a matching portion, and the concave portion ( 122) is a split point for splitting the opposing recesses and the retaining wall block of the lower surface as necessary.

In addition, the lower surface portion 121 is provided with four first groove portions 131a directly below the lower surface formed on the lower surface of the upper surface convex portion 121 so as to correspond to the number of the convex portions 121. The lower second groove portion 132 is formed in three to the number of the groove portion 122 directly below. That is, the retaining wall block 100 according to the present embodiment is formed with three split points, and the three split points are divided into quarter points, two quarter points, and one side from one side so that the retaining wall blocks can be split into equal sizes. It is formed at the 3/4 point and can make up to four with one retaining wall block in the field, and the upper recess 121 and the lower surface of the first yo Four grooves 131a are formed, and the retaining wall block shape is symmetrical with respect to the 1/2 point split point, and the block formed after splitting at the 1/2 point split point is also a split point (ie, 1). It is symmetrical around the 4/4 split point and the 3/4 split point) so that when they are split up to 4, they all look the same.

And the grooves constituting the split point (122, 132) can be divided into the groove on the groove of the split point at the work site and knocked down the hammer with a hammer to split easily, but can withstand a weaker external force sufficiently Have depth.

In addition, the retaining wall block 100 according to the present embodiment is parallel to the first groove portion 131a below and directly below the lower surface of the upper surface convex portion 121 so that the parallel first groove portion 131b is formed. This is to allow retraction construction even using the split retaining wall blocks. That is, when the retraction is reduced, the upper surface convex portion 121 is aligned with the parallel first groove portion 131b instead of the first lower groove portion 131a.

As described above, the retaining wall block 100 according to the present embodiment may be made of a block of a half size, a block of 3/4 size, and a block of 1/4 size, as necessary, at a work site. In addition, each of the blocks thus made is formed with a convex portion and a groove to enable both vertical and fusiform construction.

In addition, the retaining wall block 100 according to the present embodiment has a side through hole 151 penetrating through the side surface 150. The through hole 151 reduces the load of the retaining wall block and directs the flow of water to the side. In case of an emergency, it can be a supporter to support the retaining wall around the wire. In addition, the side through-holes in the underwater part of the river retaining wall can be used as a fish house, contributing to the conservation of the river ecosystem.
