Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combination stacking block capable of accurately responding to a retaining wall construction with a curvature, particularly a retaining wall construction with a slope, by combining two types of blocks, and a combination stacking block for this. Regarding the retaining wall construction method used.

[0002]

BACKGROUND OF THE INVENTION Conventionally, for construction of retaining walls such as revetment work, earth retaining work, etc., for example, the construction method shown in the front view of FIG. 14 and the sectional view of 14 has been adopted. That is, first, bank 2
The excavation slope 21 is formed by grinding 0 at a constant gradient, and a groove 23 along the length direction of the retaining wall is formed at a predetermined depth in the flat land 22 at the lower end of the slope 21. Then, after crushing stones 24 in the groove 23 so as to have a certain thickness and rolling them, a raw concrete is placed in a formwork (not shown) partitioned by on-site construction. A retaining wall foundation 25 is formed.

Next, after completion of the foundation 25, first, as a first stage, for example, rectangular stacking blocks 26 are arranged at a predetermined number on the upper surface thereof, and the back side thereof. A lining stone 27 is laid in the space, and a gap 28 between the stacking blocks 26 is filled with a barrel concrete 28 for fixing the stacking blocks 26.

In this way, the desired height of the retaining wall is sequentially piled up.

[0005]

2. Description of the Related Art By the way, as shown in a front view (A), a side view (B) and a plan view (C) of FIG. There is a rectangular plate-shaped front body 26f and a rear body 26b, and a connecting body 26j that integrally connects the front body 26f and the rear body 26b with a predetermined gap. The stacking block 26 having such a shape is generally called "flat stacking", and is arranged in a horizontal row so that both end surfaces of the front bodies 26f are brought into contact with each other and the front surfaces thereof are flush with each other. They are lined up, and then the joints are piled up in accordance with the above-mentioned construction method so that the joints do not coincide with each other in the vertical direction.

[0006]

However, in the above-mentioned retaining wall construction, when the retaining wall extension is almost straight,
If there is no problem, but it is a retaining wall that inclines with a constant slope and curves with a constant curvature (hereinafter abbreviated as "gradient curve retaining wall"), the retaining wall extends at the bottom and top. There was a problem that was different.

This difference is that when the slope curve retaining wall is convexly curved ("outer curve"), the retaining wall extension becomes shorter toward the uppermost stage, and conversely it is concavely curved ("inner curve"). Sometimes it gets longer. Conventionally, in order to adjust this, at the stacking stage, as shown in the front view in FIG. 17, when the curve is outside, (A) the joint 29 in the lower stage is widened and the joint 29 is gradually narrowed toward the upper stage. On the contrary, in the case of the inner curve, the joint 29 is gradually widened toward the upper stage (B) so as to absorb the difference.

However, such a method not only spoils the aesthetic appearance after completion, but also sets a varying joint spacing in advance in construction, and a special skilled worker such as a mason carefully piles it up accordingly. I had to go.
Further, it was necessary to work to fill the joint with mortar. Therefore, the work is complicated, the work efficiency is low, and the construction cost is high.

When the radius of curvature is too small to be handled by the above method, a method of laying a front surface substantially triangular triangular intermediate concrete 30 as shown in a front view of FIG. 18 has been adopted. Similar to the above method, this method also impairs the aesthetics, is inefficient in working, and increases the construction cost. In addition, the blocks 26 that are adjacent to each other are integrated by the body-mounted concrete 28,
Dividing by the intermediate concrete 30 (commonly known as "edge cutting")
Therefore, it may be difficult to secure the predetermined strength of the entire retaining wall. Also, at the actual site, this concrete
In many cases, the construction standard of G.30 was not observed, and there was further concern about strength.

There may be a method of making the shape of the stacking block 26 smaller as it goes up (or down), but this also requires several kinds of stacking blocks 26 to be formed in advance and managed, This is also very complicated and difficult to realize. Therefore, the present invention has been made by paying attention to the above-mentioned various problems, and an object thereof is to easily and accurately construct a gradient curve retaining wall of various forms by combining two types of stacking blocks. The present invention provides a combination stacking block that can be used and a retaining wall construction method using the combination stacking block.

[0011]

In order to achieve the above object, the combination stacking block of the present invention is constructed as follows.

A block (B block) formed so as to incline (y) outward toward the rear.

The curved surface along the front-rear direction may be a convex curved surface or a concave curved surface. Further, the width of the front side of each block is formed differently, and the width of the block (B block or A block) of the smaller width is formed on the front side of the block of the larger width (A block or B block). A convex portion (2a) having substantially the same length as that of the front body including the convex portion is set to be substantially the same as the front body of the block having a smaller width. Characterize.

Next, a retaining wall construction method for constructing a retaining wall having a predetermined height, which is performed by using the above-mentioned combination stacking block, is performed in the following order of steps. (A) On the constructed upper surface of the foundation, the A block and the B block are arranged by positioning one of the blocks by sliding one of the blocks in the front-rear direction while contacting both end surfaces of the front body thereof. Step (b) A / B blocks arranged by the above method are set as one set, A blocks and B blocks are alternately arranged on the upper surface of the foundation, and a desired number of sets are arranged in a horizontal row to construct the first stage. The second step to be carried out, (c) the third step of filling back-filled calculi between the rear body of each block arranged in the second step and the excavation slope, (d) the front of each block Make sure that the joints of the blocks do not match up and down on each block of the first stage constructed in the fourth step (e) second step of filling the body-incorporating concrete between the body and the rear body. , The second step is constructed by the same procedure as the first step and the second step. Step 5 go to, (f) said third
A sixth step in which the desired number of stages is accumulated by repeating the steps from the fifth step.

Further, in order to correspond to a curved retaining wall,
In the first step, one of the A and B blocks is slid in the front-rear direction, and a certain rotational movement is provided with an axis penetrating the center of the block in the vertical direction. Furthermore, in the first step, first,
Only one block (A block or B block) is placed with a predetermined number, and the other block (B block or A block) is placed with an interval left between them, and then,
The other block may be placed at each interval.

Further, on the front surface of the front body 2, there is formed a convex surface portion 2a having a trapezoidal cross section and protruding forward. next,
The other stacking block (hereinafter abbreviated as "B block")
5 is formed by concrete molding similarly to the A block, and is composed of a front body 6 and a rear body 7 each having a rectangular plate shape with a predetermined thickness, and is arranged in the front-rear direction at a predetermined interval. The front body 6 and the rear body 7 arranged facing each other are connected to each other to be integrated with each other.

Both end surfaces 6s of the front body 6 are formed as surfaces having a constant inclination angle β with respect to the front-back direction and inclined outward toward the rear. Similarly, the both end surfaces 7s of the rear body 7 are also formed into a surface having a constant inclination angle β with respect to the front-back direction and inclined outward toward the rear. In other words, these are the front body 6, in plan view.
The distance between the both end surfaces 6s, 7s of the rear body 7 is formed in a state of being tapered backward toward the rear.

Further, each of the connecting bodies 4 and 8 has a rectangular longitudinal section and a prismatic shape extending in the front-rear direction, but is not limited to this. For example, plan views shown in FIGS. ,
As shown in a side view, it may be formed in curved shapes 4a and 8a. The formation dimensions of the blocks A and B are set appropriately, but in the present embodiment, as shown in FIG. 3, the width dimension ratio L ₁ : L _{2 of the} front bodies 2 and 6 is A The distance between the contact points when the ends 2t of the two end surfaces 2s of the block 1 and the intermediate point 6c of the both end surfaces 6s of the B block 5 are set to be approximately 2: 1.

Further, the width dimension of the front bodies 2 and 6 of each block A and B is formed larger than that of the rear bodies 3 and 7 by ΔL, and the height dimension is set to be the same in both blocks A and B. There is. Furthermore, the convex surface portion 2 of the front body 2 of the block A
The width Pa of the convex portion of a and the front surface width Pb of the front body 6 of the block B
Are set to be substantially the same, and the thickness Qa of the front body 2 in the convex surface portion 2a and the thickness Qb of the front body 6 of the block B are set to be the same.

Further, the both end surfaces 2s of the front body 2 of the A block are set to have an inclination angle α, the inclination angles of both end surfaces 3s of the rear body 3 of the A block, and both sides of the front body 6 and the rear body 7 of the B block. The inclination angles of the end faces 6s and 7s are set to β of the same angle, and β> α is set. γ (= β-
α) is appropriately set according to the correspondence of the curved surface arrangement described later, and the inclination angles α and β are
6, and the thickness of the rear bodies 3 and 7, the size of the block, the strength, etc. are taken into consideration. In this embodiment, α = 43 ° and β = 45 ° are set, respectively.

Further, in this embodiment, when the blocks are placed on the horizontal plane, the front body and the rear body of each block are formed to be vertical, but in addition to this, although not shown, It may be formed so as to be inclined rearward at a certain angle as appropriate. Normally, the excavation slope 21 is provided with a certain slope (commonly called "rolling"), but it is considered that the block itself may be inclined depending on the inclination state of the upper surface of the foundation 25. [Example of Combination Arrangement of A and B Blocks] The A and B blocks formed as described above are positioned by performing various combination arrangements as described below.

As shown in FIG. 4, first, the A block 1,
The B blocks 5 are arranged on the left and right so as to be aligned in the width direction c, and the side end surfaces 2s and 6s of the front bodies 2 and 6 are brought into contact with each other and arranged so as to rub against each other. At this time, a slight gap (2ΔL) is formed between the both end surfaces 3s and 7s of the rear bodies 3 and 7 without contacting each other (hereinafter, this arrangement is abbreviated as “standard arrangement”).

Then, the A block is fixed, and both end faces 2
By moving the B block 5 to the front or the rear while making s and 6s contact each other (indicated by a chain double-dashed line), a width dimension L ₀ (= L ₁ + L ₂ ) can be changed by + m or −n.

Although the A block is fixed and the B block is moved here, it goes without saying that the A block may be moved on the contrary. Further, as shown in the drawing of FIG. 5 and FIG. 6, one of the blocks A and B is arranged in a state of being rotated by a constant rotation angle θ with an axis O penetrating the center of the block in the vertical direction. Thus, the A and B blocks can be arranged in a bent state. Of the B blocks on both sides of the A block, the B block on the left side in the plan view is + θ.
When the B block on the right side is rotated by -θ (rotate right), it becomes a convex curved surface (Fig. 5: arrow d), while the B block on the left side is rotated by -θ (rotate right), B block + θ
When it is rotated to the left, it has a concave curved surface (FIG. 6: arrow e).

Next, the inclined surfaces of both side end faces 2s, 3s, 6s, 7s of the A / B block of the above embodiment are formed to be flat surfaces, but as another embodiment, they are shown in FIGS. As shown in the plan view of the main part, it may be curved. That is,
The front body 11 of the A block 10 and both end surfaces 11s, 12s of the rear body 12 are convex curved surfaces in the front-back direction (arrow b) (in the vertical direction are linear), and the tangent line s in the front-back direction is rearward. It is formed so as to incline (x) toward the inside.

On the other hand, both end surfaces 16s, 17s of the front body 16 and the rear body 17 of the B block 15 are convex curved surfaces in the front-rear direction (arrow b), and the tangent line s in the front-rear direction thereof.
Is formed so as to incline (y) outward toward the rear. With the above configuration, the combined arrangement is similar to that of the A / B blocks 1 and 5 described above, and both side end faces 11s and 16s of each other.
Rub the curved surfaces of the
And / or rotate and move (arrows f, g: FIG. 1).
0).

Although the curved surface of the above-described embodiment (FIGS. 9 and 10) is formed into a convex curved surface, it may be formed into a concave curved surface, although not shown. [Retaining wall construction method using A / B blocks] Next, referring to the drawings, for the construction method of the curved retaining wall constructed by arranging the above A blocks 1, 10, B blocks 5, 15 in combination with each other. However, it will be described below. FIG. 11 is a vertical sectional view showing a building state of this embodiment, and FIG. 12 is a front view showing a part of the building retaining wall.

The formation of the excavation slope 21 of the bank, the laying of the back crushed stone 27, and the formation of the foundation 25 are the same as those of the above-mentioned conventional method, and the same reference numerals are given and the description thereof will be omitted. As shown in the drawing, the construction of the combination stacking block of the present invention is performed on the constructed foundation 25. (a) First, as the first step, the A block 1 and the B block 5 are set as one set, and as described above. And its anterior body 2,
6 are slid in the front-rear direction while contacting both end surfaces 2s and 6s of each other, or one of the two blocks is a central axis O
Rotate and move around to position and place. (B) In the second step, one set of A and B blocks placed by the above method is placed in a horizontal row in a desired number of sets to form the first stage. (C) Then, as a third step, the back-filled rubble 27 is filled between the rear bodies 3 and 7 of the blocks 1 and 5 which are positioned and arranged and the soil surface 21. (D) In the fourth step, the trunk concrete 28 is filled between the front bodies 2 and 6 and the rear bodies 3 and 7 of the blocks 1 and 5, respectively. (E) Next, each block is placed on each of the blocks 1 and 5 of the first stage by the same steps as the above-mentioned first step and second step so that the joints of the blocks are not vertically aligned. And make up the second stage. (F) By repeating the above third to fifth steps, each block is stacked in a plurality of stages to build a retaining wall of a predetermined height.

In the first step of the above embodiment, A
The block 1 and the B block 5 are set as a set, and the blocks 1 and 5 are placed so that they are alternately arranged side by side in the horizontal direction. However, as shown in FIG. 12, first, only the A block 1 ( Or B blocks 5 only), a predetermined number of B blocks 5
(Or the A block 1) is arranged with an interval w left therebetween so that the B block 5 can be placed in each of the spaces w, w ,.
(Or the A block 1) may be fitted to form a horizontal single-row step (this construction method is abbreviated as "spaced construction method").

The construction method according to the above procedure can be adopted for the first time by using the combination stacking block of the present invention, and thereby a remarkable effect which has never been obtained can be obtained. That is, as shown in the plan view of FIG. 13, generally, the method of horizontally arranging the stacked blocks of the curved retaining wall is the unit construction section 31.
Tensions 18 and 18 are planted on both ends of (about 20 m), and a water thread 19 is stretched between the tensions 18. A curved retaining wall was constructed by sequentially setting a certain retreat distance (arrow h) from the water thread 19 so as to obtain a desired curvature, and mounting each stacking block on the basis of this. .

In this case, since the conventional method is to sequentially arrange the adjacent ones from one side, if the setback distance (arrow h) set at the last position does not match, return to the beginning and correct. This is a complicated work that requires a lot of effort and skill. However, the combination stacking blocks 1 and 5 of the present invention are the same as the one block 1 as described above.
Only (or 5) can be placed on the basis of the water thread 19 first, and the block 5 (or 1) placed between them can be positively moved in the front-back direction. You don't have to use nerves and you can easily make corrections. Therefore, general workers can be efficiently constructed without relying on special skilled workers.

Further, conventionally, a unit construction section 31 is constructed by a set of working personnel ("1 party") composed of crane workers, special technicians, general workers, assistants, etc.
However, two sets of parties are formed by adopting the interval placement method of the present application, and one unit enforcement section 31 is provided to the first party on one block 1 side.
After placing only (or 5), the next unit enforcement section 32
Move to and try the same placement. During this time,
If the second party follows the work of the first party and sequentially places the other block 5 (or 1) in the formed gap, efficient work can be performed. . This can shorten the construction period and eventually reduce the construction cost.

In the fourth step, the in-wall concrete 28 may be injected at the same time after stacking a plurality of stages. In the above description, the A / B blocks 1 and 5 are used for explanation, but the A / B block 10,
The same applies when 15 is used.

[0037]

[Effects] With the above structure, the present invention has the following effects. (1) By rubbing one of the A and B blocks with their slanted end faces, and moving them in the front-back direction as appropriate, or by slightly rotating them, the total width of the A and B blocks is calculated. It can be appropriately changed, and can be appropriately adapted to the construction of the slope curve retaining wall of the outer curve of various curvatures or the inner curve. (2) Since the blocks, especially the front body, are in contact with each other and rub against each other, it is possible to secure more reliable strength than the conventional construction method in which the joint space is changed or the construction method using the interstitial concrete. It can be done, but it does not spoil the aesthetics. (3) In the horizontal single-row arrangement, if only the A block is first arranged at a predetermined interval and then the B block is arranged in the gap, when the interval placing method is adopted, the conventional method is used. As described above, the construction method of sequentially arranging from one side enables the construction to be performed in a short time, which in turn can reduce the construction cost. (4) Since the front surface of the front body of the A block is formed with the same convex surface portion as the front width of the B block, even if the A and B blocks are moved in the front-rear direction, the appearance is not spoiled. Further, since the combination block of the present invention is arranged to be positively displaced in the front-rear direction, the strictness in construction of accurately aligning the block front surface on the same plane is not required unlike the conventional example. Therefore, there is an advantage that a general worker such as a mason who is not a special skilled worker can easily perform the construction. (5) Conventionally, the construction extension is limited by the block length unit, but since the width dimension can be appropriately adjusted by the combination of the A and B blocks, there is an effect that it is possible to respond appropriately.
