Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to an optimal slope protection block which is used to protect the slope of a riverbank from erosion due to running water.

[0002]

[Prior Art]

 Conventionally, this kind of slope protection block is roughly classified into a so-called assembly type in which a plurality of frame members are assembled and formed on site and a finished product. The latter include a so-called plate-shaped body whose entire surface is covered with a concrete plate and a so-called frame-shaped body having a hollow portion inside, and the plate-shaped body is a It is completed by laying on the surface, and this frame-shaped body is the same as the above-mentioned assembled frame-shaped body, but construction is completed by inserting filling stones in the internal hollow part. ..

[0003]

[Problems to be solved by the device]

 However, although the above-mentioned assembly type is convenient for transportation, it takes a lot of time for assembling work, resulting in poor work efficiency. In addition, the plate-shaped body has the drawback that it does not adhere well to the ground and cannot be integrated, and the frame-shaped body has the problem that it is an excessive labor There were various problems such as being forced.

[0004]

[Means for solving problems]

 The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide a product that is easy to construct and has good adhesion to the ground to be laid. The gist of the present invention is to provide a frame body formed in a rectangular shape and a beam member that connects opposing short sides in an internal space of the frame body, and the inner portion of the frame body excluding the beam member. This is a revetment slope protection block characterized by pouring concrete into the space and integrating it with the ground.

Embodiments The present invention will be described in detail below with reference to embodiments shown in FIGS. 1 is a front view of a slope protection block according to the present invention, FIG. 2 is a sectional view taken along line II-II of FIG. 1, FIG. 3 is a sectional view taken along line III-III of FIG. 1, and FIG. IV-IV line enlarged vertical sectional view, FIG. 5 is a VV line enlarged vertical sectional view of FIG. 1, FIG. 6 is a perspective view of a slope protection block used in the lower stage, and FIG. 7 is a perspective view of a slope protection block used in the upper stage. It is a figure.

In the figure, reference numeral 1 is a slope having a predetermined inclination angle, such as a riverbank, on which slopes 2 are spread evenly, which is the tip of the slope 1. A foundation work 3 is formed by concrete in the hodome, and a sheet pile 4 made of steel, reinforced concrete piles or the like is embedded in the foundation work 3.

Reference numeral 5 is a lower slope protection block used along the river bed G, and its tip is arranged so as to be in face-to-face contact with the foundation work 3. As shown in FIG. 6, it has a rectangular shape in plan view. It is composed of a frame body 6 formed to have the same thickness, and a beam member 8 spanning between opposing short sides of the rectangular frame body 6 and partitioning the internal space portion 7 into left and right sides. The upper surface 8a and the lower surface 8b are formed one step lower than the upper surface 6a and the lower surface 6b of the frame body 6. In the figure, 5a is an inclined surface portion for engaging with the foundation work 3, 5b is a step portion for forming a joint groove, and 9 is a communication hole penetrating the side surface of the frame body 6.

Reference numeral 10 denotes an upper slope protection block which is installed at a place distant from the river bed G, and is arranged after the lower slope protection block 5 and, as shown in FIG. From a rectangular frame body 11 formed to have the same thickness and the same width as the slope protection block 5, and a beam member 13 that bridges between the opposing short sides of the frame body 11 and divides the internal space 12 into left and right sides. Although the upper surface 13a of the beam member 13 is formed lower than the upper surface 11a of the frame body 11, the lower surface 13b is formed on the same surface as the lower surface 11b of the frame body 11.

A communication hole 14 is formed on the side surface of the frame 11 at the same position as the communication hole 9 of the lower slope protection block 5. In the figure, 10a is a chamfer for joints, 15 is a joint material, 16 is gravel, and 17 is concrete.

Therefore, at the time of construction, the slope protection block 5 in the lower stage is made to contact the foundation work 3 with the slope portion 5a at the tip thereof, and the earth crushed stone 2 laid on the slope 1 is covered with an elastite or the like. The slope protection blocks 5 are connected in parallel with each other through the joint material 15, and the bolts inserted into the connection holes 9 are connected by tightening nuts. Moreover, after connecting also with the slope protection block 10 of the upper stage mentioned later, the gravel 16 is spread in the internal space 7 of each block 5 to the height which contacts the lower surface 8b of the beam member 8, and the gravel 16 of the beam member 8 is laid on it. Concrete 17 is poured to the same height as the upper surface 8a and integrated with the gravel 16 and the split stone 2 below.

Next, above the laid lower block 5, the upper block 10 is arranged up to the top of the slope 1, and the blocks 5 and 10 or 10 adjacent to each other in the vertical direction and the blocks 10 adjacent to each other in the left and right directions. The bolts inserted through the communication holes 9 and 14 are connected by tightening nuts, and the concrete 17 is placed in the internal space 12 of each upper block 10 to a height at which it contacts the upper surface 13a of the beam member 13 and the lower split Integrate with Kuriishi 2. In this case, the finishing of the surface of the concrete 17 does not require special precision because it is necessary to fill the ground or plant it after hardening.

When pouring the concrete 17, the method for forming the drainage hole 18 is applied, and the rainwater accumulated on the concrete 17 is drained from the drainage hole 18 to the riverside stone 2 etc. Let it flow in the direction. Further, joint members 15 such as elastite are connected between the upper blocks 10 arranged side by side, and the joints formed by the step portions 5b and the chamfered portions 10a are formed between the upper and lower blocks 5 and 10. The construction is completed by filling the joint material 15 into the gutter. In this case, since the joints between the upper blocks 10 are connected with the joint material 15 sandwiched therebetween, the joints can be used even when the slope is formed by a curved surface.

[Effect of the device]

 As described above, the revetment slope protection block according to the present invention comprises a frame body formed in a rectangular shape and a beam member that connects opposing short sides in the internal space of the frame body. Since concrete is cast in the inner space of the frame excluding the members and integrated with the ground, the rectangular frame is reinforced by beam members and has a high structural strength. In addition, since it is integrated with the ground by the concrete poured into the internal space, it has various effects that the resistance to water pressure is strong and it does not collapse accidentally.
