A plurality of earth retaining fence bodies constituted by nets are connected to each other and driven into the ground so as to face the ground, and a plurality of anchor members are connected to and driven into the ground, Next, a restraining material is stretched between the upper side of the fence main body and the anchor member, and then,
This is achieved by a slope construction method and an instrument thereof, characterized in that the space between the fence main body and the anchor member is filled with earth.

(Example) An example of the present invention will be described below based on the drawings. First, the structure of the fence main body according to this embodiment will be explained together with the manufacturing procedure. 1 to 3, a rectangular frame 2, which is a component of the fence main body 1, is made by bending a steel material having an engaging portion with a concave cross section into an L-shape, and forming the L-shaped steel material into two parts. Manufactured by facing each other and welding. A corner reinforcing material 3 is welded to each corner of the rectangular frame 2 to reinforce the frame 2.

Between the upper and lower sides of the frame 2, there are a plurality of L-shaped vertical reinforcing members 5 having bolt insertion holes 4 near the upper end.
Further, between the upper side and the lower side of the frame body 2, a longitudinal reinforcing member 6 having a cross-sectional shape is welded at a position intermediate between the longitudinal reinforcing members 5. Steel stakes 7 are welded to the lower side of the frame 2 at positions corresponding to the vertical reinforcing members 5 .

Between the longitudinal reinforcing members 5 and 6, horizontal reinforcing members 8 and 9 extending orthogonally thereto are sequentially inserted in a plain weave pattern, and one end of each of the horizontal reinforcing members 8 and 9 is welded to one horizontal side of the frame 2. However, the other end of each of the horizontal reinforcing members 8 and 9 is welded to one end of the adjusting bolt 10, as shown in FIG. The other end of the adjustment bolt 10 is inserted into a hole 11 formed on the other side of the frame 2, and a nut 12 is screwed onto the adjustment bolt 10. This nut 12
By adjusting the amount of tightening, the tension of the horizontal reinforcing members 8 and 9 can be adjusted as appropriate.

Thereafter, a vertical reinforcing material 13 is welded between the upper side and the lower side of the frame 2 so as to extend vertically at the intersection of the horizontal reinforcing materials 8 and 9, and this vertical reinforcing material 13 and the horizontal reinforcing material 8 , 9 are welded. Then, the contact portions of the horizontal reinforcing members 8, 9 and the vertical reinforcing members 5, 6 are welded to firmly reinforce the frame 2. In this way, the synthetic resin net 14 is fixed to the buried earth side (the right side in Fig. 3) of the strongly reinforced frame body 2 by appropriate means, and the fence body for earth-retaining is constructed. 1 is completed.

Next, the anchor member 15 and the restraining member 22 will be explained based on FIG. 5. Anchor member 15
consists of a steel base 17 with an L-shaped cross section in which a required number of holes 16 are bored, a steel pipe pile 18 inserted into the holes 16 of the base 17, and a U-shaped steel base 18 above the base 17 of the steel pipe pile 18. It consists of a plate 21 that is fastened with bolts 19 and nuts 20.

The retainer 22 is made of bar steel or the like, and one end of the retainer 22 is welded to the base 17 of the anchor member 15, and the other end is welded to one end of the adjustment bolt 23. The other end of this adjustment bolt 23 is
It is inserted into the bolt insertion hole 4 of the vertical reinforcing member 5 of the fence main body 1, and a nut 24 is screwed into the bolt insertion hole 4. By adjusting the amount of tightening of this nut 24, the degree of inclination of the fence main body 1 can be adjusted as appropriate.

Note that here, one end side of the restraining material 22 is connected to the base 17.
The other end was welded to the fence body 1 side so that the length could be adjusted, but of course, on the contrary,
The other end of the restraining member 22 may be welded to the fence main body 1, and the length of one end may be adjusted on the base side.

A method for actually constructing a slope using the construction tool configured as described above will be explained based on FIGS. 6 to 8.

The fence main body 1, the anchor member 15, and the restraining material 22 are manufactured in advance in the factory, and the fence main body 1, the anchor member 15 manufactured in the factory
And the restraining material 22 is carried to the installation site where the slope is to be created. First, the fence main body 1 moves this to the ground B.
The net 14 is placed at a predetermined position on the ground A so that it is placed on the ground B side (filling earth side), facing the net 14.
The fence main body 1 placed on the ground A is pounded on its upper part with a shovel type excavator (not shown) used for leveling the ground, thereby connecting the plurality of fence main bodies 1 to each other and stacking the piles 7 in sequence. Drive it into the ground A. In this case, the fence bodies 1 adjacent to each other are arranged as shown in FIGS. 6 and 7.
The engaging parts recessed in the lateral sides of each frame body 2 are overlapped with each other, and a plurality of fence bodies 1 are driven in as described above.

Then, one side of the base 17 of the anchor member 15 is driven into the ground B facing each of the fence bodies 1, with one side of the base 17 separated from the fence body 1 by an appropriate distance. At this time, it is preferable that the plurality of bases 17 be driven in such a manner that the distance from the fence main body 1 is alternately different in size, as shown in FIG. Between each adjacent base 17 driven into the ground B,
Each base 17 is welded with a joint material 25 of the desired shape.
Reinforce each other firmly. After reinforcing the space between each base 17 with a joint material 25, a steel pipe pile 18 is inserted into a hole 16 drilled in each base 17, and the steel pipe pile 18 is driven into the ground B.

After that, one end of the retaining member 22 is welded and fixed to the base 17 of the anchor member 15, and the adjustment bolt 23 welded to the other end of the retaining member 22 is inserted into the bolt insertion hole (the bolt insertion hole) provided near the upper side of the frame 2. 5) and screw the nut 24 on. The degree of inclination of the fence main body 1 is adjusted as appropriate by adjusting the amount of tightening of the nut 24. After adjusting the degree of inclination of the fence main body 1, the plate 21 is fastened to the steel pipe pile 18 with U bolts 19 and nuts 20. In this case, the plate 21 is fastened so as to be in contact with the retaining member 22 and facing the fence main body 1. After that, soil obtained by scraping away the ground B is filled in the space C between the fence main body 1 and the anchor member 15 as shown by the imaginary line E in FIG. The land will be cleared and leveled using excavators, etc.

FIG. 9 shows an embodiment in which the creation instruments according to the present invention are stacked in two layers, upper and lower. The second-stage fence main body 1 used here does not have the stakes 7 attached to the lower side of the frame 2. The assembly procedure in this case is to connect the plural fence bodies 1 of the first stage to each other and face the ground B,
Drive it into the ground A in the same manner as above, and then place it on the upper side of the frame 2 of the first stage fence body 1.
The lower side of the frame 2' of the second-stage fence main body 1' may be surely engaged with the assembly. The procedure for assembling the anchor member 15' and the restraining member 22' related to the second stage fence main body 1' is as follows.
Since the assembly procedure is the same as that of , the explanation thereof will be omitted.

(Effect of the invention) As described above, according to the present invention, the fence main body,
Anchor members and restraining materials can be mass-produced in factories, and on-site construction work is significantly reduced compared to conventional methods, so it is possible to shorten the construction period and reduce construction costs. In addition, since a synthetic resin net is fixed to the frame body for soil retention, rainwater and the like can be drained naturally, and disasters caused by landslides can therefore be prevented. Furthermore, since the plurality of fence bodies can be freely combined according to the topography of the site, it is possible to easily handle construction work on deformed land.
