BEST MODE FOR CARRYING OUT THE INVENTION The block material for embankment method of the present invention has a through hole in the longitudinal direction, and step-like engaging portions are provided at the upper and lower end portions of the through hole or one end portion of the through hole. A tubular foam synthetic resin block, and when the blocks are stacked one above the other, fit into an engaging recess formed by the engaging portion at the lower end of the upper block and the engaging portion at the upper end of the lower block. It is characterized by comprising a joining member made of a foamed synthetic resin which can be combined.

It is preferable in terms of water resistance, rigidity and cost. Of course, recycled materials such as foamed styrene-based synthetic resin moldings are also suitably used.

The shape of the foam synthetic resin block is not particularly limited, and examples thereof include a circle, an ellipse, a rectangle, and a polygon. From the workability when the blocks are arranged side by side in the horizontal direction, the contact area is A rectangle with many edges is preferable. The outer shape of the block may be circular, the inner shape may be quadrangular, and conversely, the outer shape may be quadrangular and the inner shape may be circular, triangular, or the like. Further, the size of the foam synthetic resin block is not particularly limited, and may be appropriately determined depending on the construction site, construction purpose, handleability, etc., but if an example of a preferable size of the unit block is shown, the outer diameter dimension is about 0.
8 to 1.5 m, its height dimension is about 0.3 to 0.8 m, inner diameter dimension is preferably about 0.4 m to 1.2 m, more preferably outer diameter dimension is about 1 m, and height dimension is about The length is 0.5 m and the inner diameter is about 0.4 m to 0.8 m.

The foam synthetic resin block may be a unit block, that is, one block. However, when a block in which a plurality of unit blocks are connected is stacked in a vast space, a stacking operation is performed. It is extremely useful because it improves efficiency. The concatenated number is, for example, 2 to 6 when the unit block has the above-mentioned more preferable size.
Numbers, especially 2, 4 are preferred. In this case, by marking the cutting position in the middle between the unit blocks, for example, in the case of a two-piece connecting block, it can be used as a two-piece connecting block as well as a nichrome wire or the like at the marking location. 2 unit blocks can be made by heat cutting with, and in the case of 4 connected blocks, of course, it can be used as 4 connected blocks. Since it is possible to obtain four types of blocks with one die, it is extremely efficient and economical.

It is preferable that a reinforcing bar groove is provided on the upper surface of the foam synthetic resin block and a drain groove is provided on the lower surface. If the upper and lower drainage grooves have the same vertical position and the same size, that is, they are vertically symmetrical, the stacking can be done without considering the top and bottom of the blocks, greatly improving workability. To do. In addition, when the reinforcing bars are placed in the reinforcement grooves and fixed with segments or mortar, cement or mortar and foamed synthetic resin blocks generally have poor adhesion, so they cross the reinforcement grooves in the middle of the reinforcement grooves. It is preferable to provide the anchor groove as described above and physically engage the cement or mortar containing the reinforcing bar and the foam synthetic resin block through the groove.

Stepped engaging portions are provided at the upper and lower ends or either end of the through hole of the block. The stepped engagement portion is an engagement recess for fitting the joining member between the engagement portion at the lower end of the upper block and the engagement portion at the upper end of the lower block when the blocks are stacked one above the other.

For example, when the unit block has the above-mentioned more preferable size, the horizontal portion that holds the joining member of the stepped engagement portion is preferably about 5 to 20 cm. The height of the stepped engaging portion is preferably about 5 to 20 cm. A block provided with a stepped engaging portion only on the upper end is used in the lowermost stage, and a block provided with a stepped engaging portion only in the lower end is used in the uppermost stage.

The joining member made of expanded synthetic resin may be a solid body or a cylindrical body having a through hole. The through hole may be one large through hole or a plurality of small through holes. The joining member has a size that can be fitted into an engaging recess formed by an engaging portion at a lower end of the upper block and an engaging portion at an upper end of the lower block. However, the joining member does not have to be completely housed in the engaging recess, and the intermediate portion except the upper and lower portions engaged with the engaging recess may be exposed. The exposed portion may be bulged so as to be substantially flush with the upper and lower blocks. Therefore, the height dimension of the joining member and the dimension of the through hole may be determined in consideration of strength, handleability, and the like. On the upper and lower surfaces of the joining member, when fitted in the engaging recesses of the upper and lower blocks, at positions corresponding to the bar arrangement grooves and drain grooves so as not to close the bar arrangement grooves and drain grooves of the block. It is preferable to provide a recess. Also in this case, if the same size is used at the same position in the upper and lower sides, that is, if they are vertically symmetrical, the blocks can be stacked by fitting them in the engaging recesses without considering the upper and lower sides of the joining member when stacking. The property is greatly improved.

In order to stack the block material for the embankment method of the present invention, which comprises the foam synthetic resin block and the foam synthetic resin joining member, a plurality of foam synthetic resin blocks are used, A joining member made of foamed synthetic resin is fitted into the engaging recess formed by the engaging portion at the lower end portion and the engaging portion at the upper end portion of the lower block, and stacked until a predetermined number of steps is reached. When the laminated block body is formed by laminating until the predetermined number of layers is obtained, the laminated block body is formed in the same manner in the horizontal direction, and the laminating operation of the blocks of a predetermined size is completed. It should be noted that the lowermost stage and the uppermost stage may be the blocks described above, but the lowermost stage has a block provided with an engaging portion only at the upper end, as described above.
Further, a block having an engaging portion only at the lower end can be used at the uppermost stage.

The laminated block bodies arranged in parallel in the horizontal direction are
It can be integrated by arranging the reinforcing bars horizontally. Further, the adjacent laminated block bodies may be integrated by inserting a T-shaped or ten-shaped connector having a protruding portion at the tip thereof. As such a joint tool,
For example, those described in JP 2000-220145 A are preferably used. Further, the laminated block body can be integrated by vertically inserting a hook-shaped connector having a protruding portion at its tip. When the reinforcing bars are arranged in the horizontal direction, it is desirable that the reinforcing bars be wrapped so that the hook portions are pierced.

When laminating the foam synthetic resin blocks, the residual soil can be filled in the through holes of the blocks as an aggregate. By doing this, the problem of residual soil treatment is solved at once, and the load is supported even in the filled residual soil portion, and since the residual soil and the block are integrated and the density increases, the load resistance and buoyancy resistance are improved. There is an increasing effect. Further, if the aggregate is concrete and the reinforcing bars are arranged in the concrete, it is possible to further laminate the blocks.

Usually, multiple pieces are fixed at required points. Then, for example, a non-combustible panel 25 or the like is attached to the H-shaped steel material 23 provided on the valley side so that the appearance of the road side surface is maintained.

After the foundation work is completed, the foundation anchor 24 is inserted into the through hole 6 of the double-row rectangular foam synthetic resin block 15 in the leveling layer (not shown) so that the block 15 is horizontally moved. Install in parallel. continue,
After fitting the joining member 9 shown in FIG. 1 to the step-like engaging portion 7 at the upper end of these blocks 15, the step-like engaging portion 7 at the lower end of the second-stage block is subsequently provided thereon. The joining members 9 are stacked so as to be fitted. Thereafter, this operation is repeated to sequentially stack blocks of a predetermined number of stages. In the meantime, as described in the above-described Example 7, the reinforcing bars 17 are appropriately fitted in the lateral direction, and then the block laminates are connected in the vertical direction by the hook-shaped connector 18 or arranged side by side in the lateral direction. The block laminated bodies are connected to each other by a T-shaped connector 21 and a dove-shaped connector 22.

The block 26 arranged on the mountain side is
As shown in the figure, normally, one having neither the bar arrangement groove 3 nor the drain groove 5 on the surface facing the slope on the mountain side is used. After a predetermined number of blocks are laminated and the individual blocks are connected and integrated by various connectors, the through holes 6 are appropriately filled with residual soil or preformed concrete pieces (not shown) as aggregate as aggregate. Increase the density as a block.
Further, when concrete or mortar is placed in the through holes 6 and further reinforcing bars are placed therein, a stronger laminated block body is constructed.

Subsequently, a plate-like body (control panel or non-combustible panel) 27 is laid on the uppermost block, and concrete 28 and asphalt 29 are successively placed on this. When filling the through hole 6 of the block with residual soil or aggregate such as concrete pieces, it is desirable to temporarily close the drainage groove and the reinforcing bar with gum tape or the like.

As described above, the case of constructing a road has been outlined as an example of the method for laminating the block material for the embankment method of the present invention. However, the laminating method of the present invention is not limited to this, and a terrace-shaped plateau or concrete can be formed. It is widely and suitably used for construction of formwork for construction and mountain construction in parks.

Further, even if wind pressure is applied from the lateral direction or some external pressure is applied during the work, the lateral displacement does not occur, so that the work efficiency is significantly improved. Further, if the blocks and the joining members are vertically symmetrical, they can be stacked without being aware of the vertical relationship, so that the work efficiency is further improved.

Further, even if the foam synthetic resin block portion is invaded by heavy rain or long rain during a typhoon, or by groundwater exuding from the mountain side, by providing drainage channels communicating with each other, drainage When the cylindrical through-hole is filled with residual soil or aggregate such as concrete, the density of the block increases and the ground surface cracks due to buoyancy. The occurrence of troubles is prevented in advance.

Further, since the foam synthetic resin block is formed in a cylindrical shape having a through hole, even when it is piled up in the field for stacking, it is not blown off even by a little wind. Further, in some cases, a wire, rope or the like can be inserted and fixed in the through hole, which facilitates storage management on site.

If the foamed synthetic resin block is arranged at a predetermined position and the remaining soil is filled in the cylinder as an aggregate, the problem of the residual soil treatment is solved at once, and the filled residual soil is also loaded. The remaining soil and the block are integrated to solve the problems of load resistance and buoyancy resistance at the same time.

When stacking the block materials and arranging them side by side, if a connecting tool such as a hook-shaped connector, a T-shaped connector, or a dove-shaped connector is used, the upper, lower, left and right blocks are sequentially connected and integrated. Therefore, even if an external force is applied after the construction due to an earthquake or the like, displacement or distortion does not occur, and the initial laminated state can be stably maintained.

Further, since the through hole is provided in the foam synthetic resin block to form a cylindrical body, the thermal efficiency of the mold at the time of molding is improved, the molding cycle is shortened, the productivity is improved, and the synthetic resin Since less raw materials are required, it is possible to reduce the block unit price.
