BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block for retaining walls constructed for protection of steep slopes, such as earth and sand, and hills, and the like. In the past, this type of retaining wall, for example, has been widely used in the form of gravity or strut type, which is carried out by directly hitting concrete in the field.

However, this type of retaining wall not only has to do various works such as concrete in the construction site, but also has poor workability in building retaining walls.

Therefore, in recent years, a means of building a retaining wall on the surface has been adopted by preparing a predetermined number of blocks in advance and accumulating them at a construction site.

However, since the block of the same dimension is a retaining wall of a certain thickness in each part, the necessary deterrent may not be obtained in the lower surface of the surface where a relatively large earth pressure is applied. In such a case, there may be a method of increasing the retaining wall thickness of the block by arranging a plurality of blocks along the corner direction of the surface (horizontal direction of the surface of the surface) on the lower surface of the large earth pressure, but simply arranging the blocks in this way. It is insignificant and cannot increase the deterrence there unless it is a conjunctive arrangement of interlocking blocks.

As a result, the coupling between the arranged blocks is almost identical to the work of crushing concrete on site as mentioned above.

In addition, each of the accumulated blocks forms a gap for drainage, but the back surface of the retaining wall flows down to the bottom along the back surface of the retaining wall formed by each block, so that the gap between the blocks cannot serve as drainage. There are many cases.

As a result, this phenomenon leads to the risk of collapse of the retaining wall since only the gap between the bottom and the block is functioning as a drainage.

An object of the present invention is to obtain a block for a retaining wall which can solve the above problems and has high stability. Hereinafter, the configuration of the present invention will be described in detail according to the embodiment shown in the drawings.

In this embodiment, as shown in FIG. 1, retaining wall blocks 1A to 1D by forming a plurality of types (four types in the figure) are used.

As a result, each of these blocks 1A to 1D differs in molding dimensions and weights from each of them, and in order to increase the amount of block 1A to block 1D, the block 1A to block 1D are set so as to be sequentially and stepwise in mass. .

Here, these blocks are referred to as 1 ton block (1A), 2 ton block (1B), 4 ton block (1C), and 6 ton block (1D) by weight.

However, these figures are used for convenience, and the tonnage on this title and the actual weight figures are somewhat different.

In addition, for the molded dimension of each block 1A-1D, the dimension of length (left and right direction of FIG. 1) lengthens longitudinally and longitudinally from 1 ton block 1A to 6 ton block 1D. It is.

In addition, the height (dimensions in the vertical direction in FIG. 1) of each block is also gradually increased in order from 1 ton block 1A and 2 ton block 1B to 4 ton block 1C and 6 ton block 10.

Among the above-listed blocks 1A-1B, 1 ton blocks 1A and 4 tons of blocks 1C, which are arbitrarily elected, are specifically described in accordance with FIGS. 2 to 5 and 6 to 9 Explain.

In the block 1A and 1C, the surface wall 2 is integrally formed on the front surface of each block body 1A 'and 1C'.

This surface wall 2 is a part which comprises the surface of the retaining wall comprised by each block.

As shown in Figs. 5 and 9, the surface wall 2 is provided with a constant dimension 5 on both sides of each block body 1A 'and 1C', respectively.

In addition, a pair of corner portions 3 and 4 protrude from the bottom of each block body 1A 'and (1C'), and one corner portion 3 extends the upper surface wall 2 downward. Each part 8 is formed in one shape, and each part 4 is formed in the each part 8 at predetermined intervals L. As shown in FIG. (See Figures 3 and 7).

However, the above-mentioned spacing L differs in size according to each block.

Moreover, as shown in FIG. 4 and FIG. 8, the both sides of the said corner part 4 are shown by the fixed dimension S 'by the both sides of each block body 1A' and 1C ', respectively.

This dimension S 'is set slightly smaller than the dimension S shown in the upper surface wall 2 above.

On the other hand, large projections 5 are formed on the upper surfaces of each block 1A 'and 1C', respectively.

However, one projection 5 of 1 ton block 1A is one, and two projections 5 of 1 ton block 1C are formed in parallel. In addition, the longest width L 'of the projection 5 shown in FIG. 4 and FIG. 8 is set equal to the space | interval L between each part 4 in each block.

Accordingly, the width L 'of the upper protrusion 5 also differs in size by each block.

In addition, in the four-dimensional block 1C, one side of the two-tone block 18, which is one step smaller than the four-tone block 1C, in the dimension r between the protrusions 5 shown in FIG. Each part 4 of the right side of a figure is set so that it may engage.

However, the dimension 1 from the surface wall 2 of the 4 ton block 1C shown in FIG. 7 to the projection 5 at the corner is the length (left and right side of FIG. 1) in the longitudinal direction of the 2 ton block 1B. ) Is set equal to the total length of

In addition, the two-tone block (1B) and the six-tone block (1D) is a difference in weight and molding dimensions compared to the four-tone block (1C) described above, but the detailed description is omitted because the configuration is an equal configuration. The construction of the retaining wall using the various blocks described above will be described.

First, the surface of the retaining wall construction site is divided into 2-4 widths, and the strength of the partitioned ground is judged, and the cut surface is cut to a predetermined height. As shown, the foundation concrete (6) is made and 6 tons of blocks (1D) are first placed on the foundation concrete (6). In this case, the corner part 4 of one 6-ton block 1D is engaged with the engaging part 6 'previously formed in the upper surface of the base concrete 6 above. The six-tone block 1D is arranged on one side or both sides of the block 1D as a starting point for the construction of the abyss.

In this case as well, the respective corner portions 4 of each appendix 1D are engaged with the engaging portions 6 'of the foundation concrete 6, and the surface walls 2 of the blocks 1D are connected to each other. Arrange face to face In this way, the installation work of the six-tone block 1D in one stage is completed in one compartment.

Between the embossed portions 3 and 4 of each of the six-tone blocks 1D arranged in this manner, a space X ₁ continuous in the width direction of one compartment on the surface is formed (see FIG. 1). The space Y ₁ is also formed between the block bodies 1D 'of the block 1D (see FIGS. 10 and 11).

In each of these spaces (X ₁ ) and (Y ₁ ), fillers such as pebbles may be added as shown in accordance with the situation of the site. Next, stack 4 ton blocks (1C) on the top of the 6-step block (1D) in the first step.

In this case, one corner portion 4 of the 4 ton block 1C is engaged between the two projections 5 on the upper surface of the 6 ton block 1D, thereby reducing the 4 ton block 1C to the 6 ton block 1D. ) The earning status is stable.

As a result, in this case, between the projections 5 of the 6 ton block 1D serves as an engaging portion for each part 4 of the 4 ton block 1C.

In addition, as described in the relationship between the 4 ton block (1C) and the 2 ton block (1B), the dimension (1) from the surface wall (2) of the 6 ton block (1D) to the corner protrusion (5) is 4 It is set equal to the tone block 1C and the full length (see FIG. 1).

Therefore, each surface wall 2 of the 6-ton block (1D) and the 4-ton block (1C) accumulated on the upper surface is in a state of one surface.

In this way, if each of the four tons of blocks (1C) is accumulated on the upper surface of each of the six tons of blocks (1D), each of the four tons of blocks (3) and (4) is the same as that of the six tons of blocks described above. Space X ₂ is configured (see FIG. 1).

A space Y ₂ is also formed between each block body 1C '(see FIGS. 10 and 11).

Fillers such as pebbles may also be added to these spaces X ₂ and Y ₂ as described above. In this way, 2 tons of blocks (1B) are accumulated on the top of 4 tons of blocks (1C), and 1 tons of blocks (1A) on the top of 2 tons of blocks (1B), respectively, and each of these blocks (1B) and (1A) For space (X ₃ ), (X ₄ ), (Y ₃ ). It is comprised and you may put a pebble etc. in these as needed.

As described above, the retaining wall of one compartment on the surface is completed. Next, the retaining wall is constructed all over the surface by adding blocks (1A)-(1D) to each adjacent section in the same order as above.

Then, a pebble or the like is placed on the rear wall of the retaining wall.

The earth pressure due to this fill acts to increase the stability of the retaining wall with respect to the retaining wall rear surface which is stepped. In addition, the back surface of the retaining wall can be received at the stepped portion and discharged through each space of each block 1A-1D (or if a pebble or the like is inserted therebetween).

In the case of the retaining wall construction, as shown in FIG. 12, for example, it is also possible to accumulate 4 ton blocks 1C on the upper surface of the 4 tons block 1C.

In this case, both corner parts 3 and 4 of the upper 4 ton block 1C are positioned so as to be pinched from the outside with respect to the projections 5 of the lower 4 ton block 1C.

As a result, in this case, the outer side of the positive projection in the lower 4 ton block 1C acts as the engaging portion for the corner portions 3 and 4 of the upper 4 ton block 1C.

In the building method of accumulating two or more of the same blocks in the vertical direction, a block corresponding to 4 tons of blocks (1C) in FIG. 6 may vary from 1 to 1 blocks of blocks (1A) to 6 tons of blocks (1D) depending on the situation of the law. You may earn 2 or more Blocks.

In addition, depending on the construction site, as shown in FIG. 13, it is also possible to construct a slope retaining wall by using blocks 1A and 1D in which each surface wall 2 is inclined to the back side.

Since the present invention can use various blocks different in length and dimension one by one in the lengthwise direction according to the local situation of each place on the legal surface of the construction site as clarified in the above description, a combination of these blocks is established. The thickness of the retaining wall can be set to a dimension in which sufficient deterrent force is obtained at each corner of the normal surface, and the retaining wall block of the present invention protrudes two front and back portions 3 and 4 on the lower surface side, and one or two on the upper surface side. The protrusions of the five protrusions 5 are constructed so that the top block and the corners 4 are sandwiched between the protrusions 5 of the bottom block when building, so that the accumulated state of each block is stabilized.

That is, the length of the upper block is formed shorter than the length of the lower block and the upper block is stably supported by the engaging portion of the lower block when the upper block is formed. Not at all. In addition, since the block body has a narrower width than the surface wall, the spaces adjacent to the blocks in the lateral direction form a space for the backfill, and a space is formed in the width direction of the tunnel formed between the front and rear parts below the block at each stage. In this case, the retaining wall is constructed without filling anything in the space where they communicate. In addition, there are many voids even when the treaties are filled, so that the back surface drains quickly and the stability is extremely high. In addition, since the block of the present invention is the bottom block of the retaining wall, the length and the size of the top and bottom are gradually larger and the weight becomes larger, so that the blocks are firmly connected to each other by the engaging portion of each block and at the same time, A strong retaining wall can be constructed.
