Description of the Related Art Conventionally, in order to protect a slope, anchors are placed on the slope at a predetermined interval, and a fixing member made of concrete is fixed to a protruding portion of the slope of the anchor tension member in a tightened state. It is used. Although this slope protection method strongly stabilizes the ground on the slope, it cannot prevent collapse of the surface layer on the slope surface and runoff of earth and sand. Therefore, in such a case, the mortar was sprayed on the slope or a slope protection net was separately attached. According to this conventional slope protection method, the installation work of the heavy fixing member made of concrete is large in scale, which increases the construction cost and lengthens the construction period.

置し、それらの間を短かい継手部材６で連結することで
曲面に沿って連接部材を配置できる。In this embodiment, a hole drilling machine of about 5 m is drilled vertically and horizontally on the slope N at intervals of 1.2 m (see FIG. 4 (a)). After drilling, compressed air is sent to clean the inside of the drilled hole H. Next, mortar is injected into the drilled holes, and the anchor tension member 1a, which is a reinforcing bar, is inserted into each drilled hole before hardening.
The upper end of the anchor tension member 1a is projected from the surface of the slope N to the ground. (See FIG. 5 (b)). Next, a non-woven vegetation sheet 4 is laid on the surface of the slope N, and a protective net 3 of a wire mesh 10 cm square from the top is covered. Protection net 3
Then, the longitudinal and horizontal connecting members 2 of about 1.3 m are placed on the anchor tension member 1a at their end portions 2b1, 2b2, 2b3.
Arrange so that 2b4 comes. The end 2b2 of the connecting member 2
2b4 are provided with steps having an integral multiple of the plate thickness of the connecting member 2 so that the heights thereof are different, and the end portions 2b1 to 2b4 of the connecting members 2 on the four sides are overlapped. (See FIG. 5 (c)). Insert the ground projecting portion of the anchor tension member 1a into the through holes 2c of the end portions 2b1 to 2b4 of each connecting member 2, and attach the nut 1b1 to the penetrating ground projecting portion,
The connecting member 2 is fixed so as to be pressed against the slope N by tightening with the nut 1b1. Next, the cylindrical cap 1b2
The outer surface of the cylindrical cap 1b2 and the nut 1b1.
-Fill between the anchor tension members 1a with mortar (see Fig. 5 (c)). This improves rust resistance and fixation of the upper end of the anchor tension member. In this way, the vertical and horizontal connecting members 2 are connected to each other by the anchor 1 and pressed against the slope N. By pressing the connecting member 2 against the slope N, the protective net 3 and the vegetation sheet 4 are brought into close contact with the surface of the slope N. If necessary, the protective net 3 and the connecting member 2 are connected by metal fittings / wires. In this way, the protective net and the vegetation sheet 4 are covered so as to be pressed against the slope N, so that the runoff of the slope surface soil due to rainwater
Prevents collapse and keeps water retention to improve vegetation.
(See FIG. 5 (d) and FIG. 1) Since the connecting member of the present invention has a length of about 1.3 m and a weight of about 10 kg, one worker can carry it by hand to the slope and adjust the installation, so that workability is improved. Is good. At a place where the slope is curved, a short connecting member 5 is arranged as a connecting member along the curved surface, and a short joint member 6 is connected between them to arrange the connecting member along the curved surface.

There is. Further, since the connecting member has an L- or T-shaped cross section, this vertical portion serves as a scaffold for easy work, and the collapse of earth and sand can be effectively prevented. In addition, vegetation sheets and protective nets prevent the topsoil from collapsing and flowing out, and improve the vegetation by making close contact. Further, since it is a simple member, it can be constructed at a low cost and with a short construction period.
