Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relatively large retaining wall and gutter block that is laid between a road and areas other than the road on both sides of the road.

[0002]

2. Description of the Related Art Conventionally, as this type of technology,
Gate-shaped gutter blocks used when there is no difference in elevation in other areas, and horizontal anchors on one side of the blocks used when there is a difference in elevation between the roads and the surfaces on both sides of them (called the toe part or heel part). That is integrated)
Two types are known from Japanese Utility Model Publication Nos. 62-16179 and 63-2537, respectively. Further, a structure is also known in which the base portion is separately preliminarily molded and then attached later. However, the connection between the drainage block and the anchor block requires a special metal fitting in the former publication, and the drainage block cannot be constructed unless the anchor block is constructed correctly first.

Further, in the latter publication, the connection between the drain block and the anchor block is a dovetail groove and the structure of the dovetail, and the connecting work is difficult, and a large stress concentration occurs only in this connecting part. May be destroyed. In addition, although a structure that tightens with two large bolts on the top and bottom is also shown, it is difficult to pass a large bolt in a narrow place, and in order to facilitate the work,
It is not realistic because it requires a large amount of digging around the periphery, which increases labor and construction costs. Furthermore, depending on the construction site, the drain block block may be used alone without connecting the anchor block.

[0004]

Therefore, an object of the present invention is to easily deal with various situations at a construction site,
The purpose of the present invention is to provide a drainage block and an anchor block that can fully fulfill the role of the drainage block.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1 shown in FIG. 1 to FIG. 6 will be described. However, regarding the portion already described in the section of means for solving the problem, this is incorporated and repeated description is omitted. To do. On the inner peripheral surface of the bolt through hole 11,
A plastic pipe 13 and plugs 12 at both ends of the bolt through hole 11 are buried by being inserted during molding of the drainage groove block A (see FIG. 3). Drain block A
Has a height of 1 to 2.5 m and a width of 50 cm.
Although the length is 1 to 1 m and the length is 1 to 2 m, the size itself has no restrictive meaning. A rectangular opening 15 is provided in the central portion of the ceiling wall 14 of the drainage block A, and a flange 16 is provided on the inner edge of the drain opening block A so that a seal or an iron grid lid (not shown) can be placed on the opening 16 inward. . The opening 15 is for fitting the above-mentioned lid and for reducing the weight at the time of construction and facilitating the construction.

An anchor block B is provided on the outside of the side wall 10.
Is formed with a shallow recess 17 into which the upright wall 25 can be fitted, and when the anchor block B is aligned with the recess 17 and lowered, the tightening bolts 30 securely engage the cut groove 2.
It is designed to match the position 1 so that work can be done quickly and accurately. The drainage block A and the anchor block B are usually made of cement concrete containing reinforcing steel or metal lath, but instead of cement, thermoplastic waste is reheat-melt molded, or the thermoplastic waste and other materials are used. A mixture of the above wastes is also included in the embodiment of the present invention.

Further, in the taper guide groove surface 21a portion of the anchor block B, since the escape space S for escaping the washer 31 and the tightening nut 32 is also provided in the horizontal base portion 23, the anchor block described above is provided. The construction can be performed with a larger inclination angle of B in the flow direction with respect to the drainage block A, and the anchor block B can be constructed horizontally even if the drainage block A is steeply inclined. Further, the anchor block B is equipped with a spectacle bolt 26 for passing a lifting wire or a rope on the attachment / detachment itself.

As an example of the plug 12 that can be easily crushed or removed, the plugs illustrated in FIGS. 4 to 6 can be used. The illustrated plug 12 is made of a thin synthetic resin injection-molded product, and is a plug main body 37 integrally formed with an end plate 35 that completely closes the bolt through hole 11 and a semi-cylindrical first trough 36 extending in a direction perpendicular to the end plate 35. There is. Ribs 40 are formed axially outwardly on both edges 38 of the first gutter 36. On the other hand, in the semi-cylindrical second trough 39, which is a member separate from the plug body 37,
A rib receiving groove 41 that fits into the rib 40 of the first gutter 36 is formed. When the rib receiving groove 41 of the second gutter 39 is fitted to the rib 40 of the first gutter 36, one cylindrical part is formed by the first gutter 36 and the second gutter 39 part, and an inner space of the cylindrical part is formed. It becomes the bolt through hole 11. The plug 12 is embedded and fixed by the insert of the drainage groove block A.

Therefore, when the tightening bolt 30 is not used, the bolt through hole 11 is completely closed by the end plate 35. When removing the stopper 12, when the end plate 30 is pryed open with the tip of a screwdriver or the like,
Since the gutter 36 and the second gutter 39 are originally separate members, the rib 40
The rib receiving groove 41 is easily disengaged, and the plug 12 has the bolt through hole 1
Easy to remove from 1. The stopper 12 is not limited to the above exemplified product, but can be integrally molded with a fragile molded product (recycled plastic recycled product) or the like, and can be easily removed because it can be easily cracked by poking it with a driver or hammering it. .

As shown in FIG. 7, the plug 12 is provided only inside the side wall 10 of the drainage block A, that is, on the water passage side of the drainage block A, and on the outside where the anchor block B can be attached. You can choose not to. The stopper 12 of FIG.
Is made of plastic, and the outer peripheral surface of the plug 12 is formed into a tapered surface whose diameter decreases toward the tip, and is press-fitted in advance at the end of the vinyl chloride pipe 13. A circular projection 12a is formed at the center of the base end surface of the stopper 12, and the sponge disk 40 fitted in this has a circular projection 12a.
Is glued to. The pipe 13, the plug 12, and the sponge disc 40 thus combined are attached to the molding frame of the drainage groove block A by a mounting jig press-fitted to the other end of the pipe 13, and the sponge disc 40 is It is compressed by the molding frame.

Thus, as shown in FIG. 7, the pipe 13, the plug 12 and the sponge disc 40 are embedded by insert molding so as to traverse the side wall 10 of the drainage groove block A inward and outward. When using the tightening bolt 30 for mounting the anchor block B, if a rod member having an appropriate length is inserted into the pipe 13 from the outside and the plug 12 is pushed,
The stopper 12 and sponge disc 40 are easily removed. When the anchor block B is not attached, the drainage block A
Due to the pressure of the water flowing inside, the sponge disk 40 and the stopper 1
The plug 12 does not come out of the side wall 10 because the 2 is further pressed in the direction of the pipe 13.

[0018]

According to the invention of claim 1, since the bolt through hole 11 is closed by the plug 12 even when only the drainage groove block A is used, the water in the drainage groove leaks to the outside. Even if the cast-in-place concrete is poured up to the height of the bolt through hole 11, the mortar component does not flow out from the bolt through hole 11 and the concrete strength of the portion is not weakened. Further, at the corner portion 20 position of the anchor block B, since the notch groove 21 is long in the vertical direction and is notched from the bottom surface 22 of the horizontal base 23 to above the upper surface 24, the tightening bolt 30 is drained. After passing through the bolt through hole 11 of the block A, the anchor block B can be hung and the work efficiency is good. An anchor block is provided on the outside of the side wall 10.
The shallow recess 17 into which the B standing wall 25 can be fitted is formed.
Align the anchor block B with this recess 17 and descend.
When tightening, make sure that the tightening bolts 30 make sure that the notch groove
Since it matches the position of 21, the work can be done quickly and accurately.
Furthermore, the anchor block B is set to the flow direction of the drainage block A or in correspondence with the inclination of the installation ground,
It can be arranged in a slanted manner and can be fixed by tightening, and has an effect of keeping a high supporting force when the drainage groove block A inclines in the flow direction or in accordance with the situation of the installation site.

According to the second aspect of the invention, in addition to the above effects, when the anchor block B is suspended, the tapered guide groove 21a serves as a positioning guide, so that the suspending work is further facilitated and the work is performed. You can save time.
