Description

The present invention relates to a method for manufacturing an aggregate using a used concrete block used for slope protection of an inclined land.

  A revetment formed by laying a concrete block on the slope of a dike, etc. may then be removed for some reason.

  For example, when repair is necessary due to the ground subsidence, it must be removed once. Or, when building a bridge on a dike, the block of the bridge construction site may be peeled off in accordance with the construction of the pier. In addition, for various reasons, the block may be peeled off from the construction site of the previously constructed block.

  In general, the blocks are laid side by side on a flat ground or slope (hereinafter referred to as “slope”) to be enforced, and they are skewered with reinforcing bars to prevent peeling due to increased water. Or, it is designed so that it can cope with a slight settling of the slope. Therefore, when peeling off, it will peel off while removing such a reinforcing bar.

The peeled blocks are often state-owned property or prefecture property and cannot be easily disposed of. In some cases, it may be crushed and reused as a base material for roads, etc., but crushing and other processing costs will increase.

  For this reason, it is often stored on the peeled site. The stored used blocks may then be used for revetment work at another location.

  However, even when loading and storing on the peeled site, it takes time to load each block. Also, when peeling off, place a small amount immediately after peeling off in a temporary place near the place where it was peeled off, then move it again to a place for long-term storage at the site, and then move the moved place to Since it is moved again to get in the way of the construction of this, the effort to move is burdened.

  In addition, long-term storage at the site requires management such as whether the stacked blocks are not collapsed or the quantity is reduced, which is troublesome.

  In addition, after such long-term storage at the peeled site, when there is a way of reuse at other construction sites, it takes time to load the truck.

  On the other hand, as shown in FIG. 16, it is conceivable to connect the blocks 100 with wires 101 to form an aggregate (Patent Document 1). Conventionally, this was done by laying blocks one by one on the slope at the site, and through the reinforcing bars, but with block assembly 100, the block assembly was passed through wires at the factory before installation. Therefore, at the construction site, it is sufficient to lift it with a crane or the like and lay it on the slope, which has the advantage of greatly simplifying the construction.

Further, such a block assembly 100 is bent when it is lifted. For this purpose, as shown in FIGS. 17 to 18, at least the side surface 103 of the block 102 to be used is tapered above the penetrating portion 104 to correspond to the bending. In the case of a block without this taper, for example, if it is a rectangular parallelepiped block 105, as shown in FIG. 19, when the block is bent, the upper corners 106 of the block collide and the side surface opens downward (reference numeral 107). ). However, if it opens like this, the opening allowance 108 will be made on the wire. When the block aggregate in such a state is placed on the slope, there is a disadvantage that the wire that has been the opening allowance 108 remains between the blocks as shown in FIG. Therefore, in order to avoid this, the upper part is tapered from the penetration part. Further, the penetrating portion is disposed below the center of gravity.
Japanese Patent Publication No. 5-85695

  However, most existing construction sites have not used such a block assembly, and naturally, an opening due to bending when lifted is caused. Of course, since there are various shapes other than a rectangular parallelepiped in the block, some blocks are suitable for a block aggregate that does not open downward even if it happens to bend depending on the size and shape. However, in many cases, problems such as those shown in FIGS. 19 to 20 occur and are not suitable for block aggregates.

  In addition to such problems related to block aggregates, there are many existing construction sites that do not respond to vegetation as seen in recent blocks. In response to vegetation, attempts have been made to provide pits on the sides of the block, and soil voids such as holes that penetrate the block up and down, which are called vegetation blocks. . With this vegetation block, plants can grow from the voids, which is useful for greening the embankment, but many of the peeled blocks are not considered for such vegetation. There is also a problem that the revetment and other greening cannot be achieved if reused.

In view of these problems, it is an object of the present invention, from the existing enforcement site when peeling off the blocks, storage and of the block, the collection of easy used blocks movement during such re-use provides a manufacturing method, in that case a collection of blocks suitable for vegetation is to provide a particular contribute manufacturing process becomes more easy to store in the field of the block.

In the invention of the method for producing an aggregate of used blocks according to claim 1 of the present invention, the concrete blocks in which the insertion parts for passing the long material are communicated are arranged in the direction of the communication and the insertion parts are arranged in the insertion part. The long material is inserted, and the block is peeled off from the existing construction site laid on the slope or flat ground as an aggregate of the blocks, and many of the used blocks that have been peeled off at the construction site, by inserting the wire as long material into the insertion part and the connecting Gaité coercive pipe assembly to a predetermined length, to the archival collection thereafter length matched to the new construction site a fixed to of The length is adjusted by increasing or decreasing the number of blocks.

  As a result, even when the block is stored at the site where the block is peeled off, the block can be moved in units of blocks, so that the movement accompanying the storage or change of the storage location is facilitated. In addition, when reused at other sites, loading and unloading to trucks is easy, and at new construction sites that are reused, laying can be done in block aggregate units, making construction easy. become.

Block invention of a method of manufacturing the assembly of claim 2 Symbol placement of used blocks is a manufacturing method of claim 1 Symbol placement, which by deflection of the assembly occurs when lifting the longitudinal ends of the assembly, adjacent Since the side surfaces facing each other open downward, the mouth portions of the insertion portion communicating with the side surfaces also open, and this opening relates to the case of a block aggregate in which a long material can be opened. That is, this aggregate is a new arrangement of used blocks in the aggregate according to claim 1 in which an additional block having a shape different from that of the blocks is appropriately inserted between the used blocks. In this case, as the additional block, a block formed in a shape that does not open the mouth portions of the side insertion portions is used.

As a result, even when the assembly is lifted by a crane or the like, no opening allowance is generated in the wire, and satisfactory construction can be performed. Further, it is possible to avoid the block being damaged due to the upper corner of the block colliding.

Present invention provides a method for preparing a collection of used blocks of claim 3 Symbol placement is a manufacturing method of claim 2 Symbol mounting, characterized in that the additional blocks, used blocks with a height than used blocks And

  As a result, irregularities can be formed in each block height in the block aggregate, and after laying the block aggregate, covering the top of the block aggregate will cause the used block part to become a concave one, and a large amount of cover will be deposited here. be able to. In addition, if the laid block aggregate is uneven, it will help prevent the soil from slipping off.

Present invention provides a method for preparing a collection of used blocks of claim 4 Symbol mounting is a manufacturing method according to claim 2 or 3, wherein additional block is a block for vegetation having a void portion can hold the soil It is characterized by using. As a result, revetments using vegetation blocks can be used even for revetments that reuse used blocks.

Also by the present invention, it facilitates the storage operation and the mobile work, and since the management unit able to aggregate units, also be accurate in such quantity management.

According to the above invention, when a block is peeled off from an existing enforcement site, the block can be easily stored or re-used for reuse. In addition, laying work is facilitated when reused. In this case, even if the used blocks that have been peeled off are unsuitable for vegetation, an aggregate of blocks suitable for vegetation can be obtained by adding new blocks.

Next, an embodiment of the present invention will be described with reference to the drawings.
(Embodiment 1) FIG. 1 shows a three-side view (upper left: plan view, lower: front view, upper right: right side view) of a used block 1 peeled off from an existing construction site. The used block 1 has a substantially rectangular parallelepiped shape. The long side surface 2 is provided with two insertion holes 3 in parallel as insertion portions into which reinforcing bars have been inserted.

  Also, FIG. 2 shows a three-side view (same as above) of the additional block 4 that is appropriately sandwiched between the used block arrangements. The additional block 4 is generally formed in a rectangular shape in which the shape of the bottom surface 5 is substantially the same as the bottom surface 6 of the used block 1. The side surface 7 rises from the four sides of the bottom surface 5, but two side surfaces 7 a rising from the long side 8 of the bottom surface 5 are provided on a tapered slope, and the upper surface 9 of the block is narrower than the bottom surface.

  In addition, two vertical grooves 10 are provided in one of the two tapered side surfaces 7a to form a gap 10 for vegetation. The tapered side surface 7a is also provided with two through-holes 11 as penetrating portions, and has the same spacing and the same height (height from the bottom surface 5 of the block) as the through-hole 3 of the used block. . Further, two anchor holes 12 are provided on the upper surface 9 of the additional block 4 for connection with other adjacent additional blocks.

  In addition, although it is the above-mentioned tapered inclined surface 7a, this is strictly a surface perpendicular to the bottom surface 5 from the bottom surface 5 to the insertion hole 11, and the upper surface from the insertion hole 11 is a tapered inclined surface 7a. . The side surface 7b rising from the short side 8 'of the bottom surface 5 is perpendicular to the bottom surface 5, but is trapezoidal because it is sandwiched between the tapered side surfaces 7a.

  There is no standard for the size of the rectangle on the bottom of the block, and there is no standard for the interval and height of the through-holes 3 and 11, so an additional block 4 that matches the used block 1 is prepared in advance. is there. In general, this is newly manufactured in accordance with the used block.

Next, a collection of used blocks using the above used block 1 and additional block 4 will be described. First, an additional block corresponding to the block at the existing construction site is prepared, brought into the site and prepared.

And the work which peels a block is performed in the field, and if it peels, the used block 1 and the prepared additional block 4 which were peeled will be arranged in the direction of these insertion holes 3 and 11 alternately. As shown in FIG. 3, the two insertion holes (3, 3), (11, 11) are passed through a U-shape with a single wire 13. The aggregate 14 of the used blocks obtained by connecting the wires 13 in this manner can be lifted as shown in FIG. 4 by a device such as a crane, and is lifted and moved and placed in a predetermined storage location. It is. When lifting, the loop 15 of the U-shaped push-back portion is used for locking to a crane or the like, and the open end 16 of the wire on the opposite side is held by the lifting device and lifted horizontally. When moving from the storage place placed in this way to another place or for loading on a truck, it can be lifted in the same way. As described above, the block assembly 14 is suitable for moving for storage or for moving to another construction site.

When it is lifted in this way, the aggregate 14 of used blocks bends as shown in FIG. However, as shown in FIG. 5, since the side surface 7a adjacent to the used block 1 is a tapered slope, the additional block 4 opens to the side surfaces 7a and 17 facing each other even when the aggregate 14 of the used blocks is bent. As a result, the opening portions 18 and 18 of the insertion portions of the side surfaces 7a and 17 do not open. Therefore, there is no need for the wire opening allowance as pointed out in the subject of the invention.

Therefore, when reusing at a new construction site, the entire assembly 14 of used blocks can be laid, which is efficient. Further, since the opening allowance does not occur in the wire 13 when it is lifted, an unnecessary gap is not left between the blocks 1 and 4 even when the wire 13 is placed on the slope, and the operation proceeds well. Depending on the construction site, the length of the used block assembly 14 that has been laid may or may not be sufficient, but in that case, the block 14 can be removed by shortening it or by adding a block to make it longer. It is.

Then, as shown in FIG. 6, after the used block aggregate 14 a is laid on the slope, another row of block aggregates 14 b is laid next, and the upper end wires are fastened with clips 19. In this way, a collection of used blocks 14 in tandem is laid one after another. In this case, adjacent rows ( used block aggregates 14) are connected by the anchor holes 12 provided on the upper surface of the adjacent additional blocks 4 in each row. That is, the connecting material 20 made of a steel plate is spanned between the anchor holes 12 so as to straddle the rows, and the anchor holes 12 are tightened to the anchor holes 12. This stabilizes the used block assembly 14 from being displaced and the used block assembly 14 being depressed or peeled off due to ground subsidence.

When the slope laying is completed as shown in FIG. 7 by repeating such an operation, the covering soil 21 is placed on the aggregates 14 of these used blocks . The covering soil 21 covers the entire assembly 14 of used blocks. However, when the entire covering block 14 is left covered, the covering soil 21 is flush with the upper surface 9 of the taller additional block. You may pay as much as you can. In any case, the aggregate 14 of used blocks laid at this time is low as shown in FIG. 8 because the tall additional blocks 4 and the short used blocks 1 are alternately arranged. The covering soil 21 is accumulated in the hollow portion (the earth retaining portion 22) of the used block. Since the covering soil 21 accumulates in such a soil reservoir 22, it becomes a place for vegetation such as grass. In addition, the additional block 4 itself is filled with soil in two vertical grooves that are recessed in the tapered side surface, and this is a void portion 10 for vegetation (see FIG. 6), and the soil accumulated in the void portion 10. Vegetation is also made by.

(Embodiment 2) In Embodiment 2, the used block 1 is the same block as Embodiment 1 (see FIG. 1), and only the additional block 23 sandwiched between them is different from Embodiment 1. As shown in FIG. 9, the additional block 23 is provided with side surfaces 24 (two surfaces) facing the used block 1 on a tapered slope, and the upper surface 25 of the block 23 is narrower than the bottom surface 26. Same as Example 1. One of the two side surfaces 24 is provided with two vertical grooves 27, and the other side surface 24b is provided with one large vertical groove 28, both of which are vegetation gaps 27, 28. Further, two insertion holes 29 are provided through the tapered side surface 24. In addition, two anchor holes 25a are provided on the upper surface 25 of the additional block 23, as in the first embodiment, for connection with other adjacent additional blocks. The additional block 23 of the second embodiment also has an upper surface 25 higher than the used block.

The manner of using additional blocks 23 are the same as in Example 1, arranged alternately with the used block 1 removed from the existing construction sites and assembly 30 of used blocks as shown in FIG. 10, this local They are stored or transported to a new construction site where they are laid. FIG. 10 is a diagram laid at a new construction site, and the void portions 27 and 28 are larger than those in the first embodiment, so that vegetation is excellent. Similar to the first embodiment, the earth retaining portion is formed due to the difference in height between the used block 1 and the additional block 23.

(Embodiment 3) In Embodiment 3, the used block 31 is as shown in FIG. 11, and the surface 33 (side surface) adjacent to the additional block 32 described below is tapered. Only one through hole 34 is provided.

  Since the side surface 33 of the used block 31 is tapered, the side surface 35 of the additional block 32 shown in FIG. 12 is not tapered as in the first and second embodiments, and is perpendicular to the block bottom surface 36. It is formed as follows. In other words, the additional block 32 is substantially a rectangular parallelepiped as a whole. However, the difference from the first and second embodiments is that the lateral width W1 of the side surface 35 adjacent to the used block 31 is 1 than the same lateral width W2 of the used block. .5 times longer. Unlike the first and second embodiments, the height H1 of the additional block 32 is the same as the height H2 of the used block 31.

Therefore, when an aggregate of used blocks is formed using this additional block 32, as shown in FIG. 13, used blocks 31 “two” and additional blocks 32 “one” are arranged alternately. is there. The “two” used blocks 31 are arranged side by side in a direction perpendicular to the row, and at that time, only one through hole 34 is arranged in the direction of the row direction. Therefore, two through holes 37 are provided on the long side surface 35 of the additional block 32 at a position where the additional block 32 can communicate with the through holes 35 of the two used blocks 31. Thus, the aggregate 38 of used blocks of Example 3, the two used blocks 31 and one additional block 32 are those arranged alternately, each side vertical aggregate 38 of used blocks Are formed in irregularities. And when this aggregate of used blocks is used at a new construction site, as shown in FIG. 13, a large gap 39 due to the unevenness is formed between two additional blocks arranged side by side. It can be done.

  Further, the two side-by-side used blocks 31 are sandwiched between the two additional blocks 32 from the front and rear, so that the earth accumulation part 40 as shown in FIGS. Formed in between, this is also useful for vegetation.

  Further, as shown in FIG. 15, the earth accumulation portion 41 is formed by the taper of the side surface 33 of the used block even between the blocks arranged in a column of the block aggregate. In addition, this can be said to any of Embodiments 1 to 3. However, when paying attention to the columns of the block aggregate, in order to allow bending when suspended, a space in which adjacent side surfaces are opened upward. However, as a result, it is also made in the earth reservoir.

  The present invention is not limited to the above-described embodiments, and may be implemented in any manner without departing from the spirit of the present invention. The used blocks and the additional blocks are not arranged every other block, but may be arranged in other ways. The used block is not limited to one type, and a plurality of types may be used, and a plurality of types of additional blocks may be used as well.
