To protect the slope by preventing the stones and rocks from being dug and removed by the water with the underside of the concrete protection body, and the water that tends to collect between the protection body and the slope, The slope is protected by passing between the opening of the protective body and the filling member to escape from the outside, and storing the earth and sand that is going to flow out from the slope into the gap between the filling members so as not to flow out. The protector is fixed so as to be pressed against the slope by the ground anchoring portion of the anchor. Even when the slope faces waves, the impact force due to the waves is dispersed by the filling member. If a concrete protective body is placed so as to cover the exposed surface of the slope from the area between the anchors on the ground, make sure that the anchor is sufficiently reinforced on the slopes, and The surface of the slope exposed from above is covered with a protective body to allow water to pass therethrough, and the slope is protected so that the earth and sand and rocks do not flow out even if washed with water.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described with reference to the drawings. Example 1 (see FIGS. 1 to 3) In Example 1 shown in FIGS. 1 to 3, the anchor penetrates the protective body, the protective body is made of concrete having an internal space and a large number of openings, and the protective body is made of concrete. A slope protection structure in which the opening on the lower surface side is made smaller than that on the upper surface side, an engaging portion is provided at the end of the protective body, the ground anchoring portion of the anchor is a cross shape, and the filling member is a porous pumice stone. This is an example. FIG. 1 is an explanatory diagram of a slope protection structure according to the first embodiment. FIG. 2 is a plan view of the slope protection structure according to the first embodiment. FIG. 3 is an explanatory diagram illustrating a connection portion between the protection bodies of the slope protection structure according to the first embodiment. In the figure, 1 is a protective body made of concrete, 1a is an upper surface of the protective body, 1b is a lower surface of the protective body, 1c is a pumice used as a filling member, 1d is an engaging piece, 1e is an engaging concave portion, 2 is an anchor,
2a is a ground fixing unit, 2b is a tension member, and 30 is a slope.

In the first embodiment, as shown in FIGS. 1 to 3, the protective body 1 is made of hollow concrete having a space inside. Protective body upper surface 1 of this concrete protective body 1
a and a large number of openings communicating with the internal space are provided in the protective body lower surface 1b. Further, the opening of the lower surface 1b of the protection body is made smaller than the opening of the upper surface 1a of the protection body. The upper surface 1a of the protective body and the lower surface 1b of the protective body have a rectangular shape, and constitute a box-shaped protective body 1. A hole penetrating the upper and lower surfaces is provided at the center of the protection body 1. Next, a large number of pumice stones 1c larger than the openings of the upper surface 1a and the lower surface 1b of the protective body are sealed inside the protective body 1 having a box shape. The pumice 1c has a porous surface. Next, as shown in FIG. 2, an engaging piece 1d is provided on the right side surface and the upper side surface of the protective body 1 so as to protrude outward from the side surface, and an engaging piece is provided on the left side surface and the lower side surface of the protective body 1. An engaging recess 1e that can engage with 1d is provided. Next, in the anchor 2, the ground fixing portion 2a has a cross shape, and the length of the cross is slightly shorter than the distance from the upper side to the lower side and the left side to the right side of the protective body upper surface 1a and the protective body lower surface 1b each having a rectangular cross shape. A tension member 2b is provided which extends downward from the center of the fixing portion 2a. A lower portion of the tension member 2b is provided with a widened portion so that the anchor driven into the ground does not come off.

The protective body 1 is arranged such that the lower surface of the lower surface 1b of the protective body 1 is in contact with the slope. Next, the tension member 2b of the anchor 2 is installed on the slope so that the tension member 2b of the anchor 2 is driven into the ground so as to penetrate the center of the protection body 1. Further, the anchor 2 is driven into the ground, and the cross-shaped ground fixing portion 2a of the anchor 2 strongly presses the protective body upper surface 1a of the protective body 1 toward the slope. Thereby, the protection body 1 is firmly fixed to the slope.
Next, another protection body 1 is attached adjacent to the protection body 1. In this case, as shown in FIG. 2, the protection recesses 1e on the left side and the lower side of another protector 1 are engaged with the engagement pieces 1d provided on the right side and the upper side of the protector 1, respectively. Connect the bodies together. As a result, the protection body 1 is attached to the slope with higher strength. In this way, if the slope is covered with a plurality of protection bodies 1, this slope is provided in a dam or a river, and may be immersed in water or subject to waves due to a change in water level. Even if it becomes
First, a water force such as a wave impact force can be prevented by the ground fixing portion 2a of the anchor 2 and the protective body upper surface 1a of the protective body 1. Further, water collides with the opening of the upper surface 1a of the protection body. However, since a large number of pumice stones 1c are sealed in the protection body 1, the force due to the water is dispersed. Therefore, since no large force is applied directly to the slope, there is no sudden excavation by the waves.

[0010] When rocks or stones on the slope are coming off the slope, the rocks or stones may come off the slope because the lower surface 1b of the protective body 1 of the protective body 1 is pressed against the slope. There is no. Further, since the opening of the lower surface 1b of the protective body is made smaller than the opening of the upper surface 1a of the protective body, even a relatively small stone on the slope does not easily move into the inside of the protective body 1. Also, even if it moves to the inside of the protection body 1, the pumice 1c
The gap between the pumice stones is complicated and narrow, so that stones that enter the inside of the protective body can be easily stopped. The outflow of earth and sand on the slope can be effectively prevented by the small size of the opening of the lower surface 1b of the protective body that is in contact with the slope and the gap between the pumice stones that are intricately complicated. With respect to water, the opening on the upper surface 1a of the protective body 1 and the opening on the lower surface 1b of the protective body 1 are sufficient openings, and the gap between the pumice stones 1c sealed in the protective body 1 is sufficiently water. Since the water passes through, water remains between the protection body 1 and the slope, and the water does not form a gap between the protection body 1 and the slope. Similarly, when groundwater or the like tries to seep into rivers and dams through the slope, the water seeps out without any problem. Furthermore, since the pumice 1c in the protective body 1 is porous having fine irregularities on the surface, microorganisms and plants are easily fixed. Therefore, it can contribute to stabilization of the slope by the roots of the plant regardless of whether it is underwater or on the water. As described above, by using the slope protection structure of the first embodiment, it is possible to stably protect a slope provided in a place where it may be immersed in water depending on the water level or may be covered with water like a wave. it can.
