The earth retaining members 1 adjacent to each other in the longitudinal direction are connected by the connecting member 3. The connecting member 3 is inserted and fitted so as to be inscribed in an end portion of the retaining member 1, and has a height and a thickness corresponding to an inner height and an inner thickness of the retaining member 1, respectively. They are almost equal. The connecting member 3 is provided with a protruding piece 3b in which a through hole 3a is formed on the side of the opening 1a having a substantially C-shaped cross section of the earth retaining member 1. The through-hole 3a is penetrated in the longitudinal direction of the earth retaining member 1 in a state where the earth retaining member 1 is connected. Then, the tightening member 4 is passed through the through-hole 3a, and the pile 2 and the connecting member 3 are tightened by the tightening member 4, whereby the earth retaining member 1 is fixed along the periphery of the site 20. Note that the pile 2 may be made of wood or metal, and a pipe may be used instead. Further, the tightening member 4 may be a band, a string, a wire, or the like.
[0013]
FIG. 3 shows a second example of the embodiment of the present invention.
In the second example, similarly to the first embodiment, the pile 2 is driven into the periphery of the site 20, and the earth retaining members 1 adjacent to each other in the longitudinal direction are connected by the connecting member 5. What differs from the first example is the direction in which the connecting member 5 penetrates the through hole 5a and the method of fixing the connecting member 5 to the pile 2. That is, the connecting member 5 is provided with a protruding piece 5b in which a through hole 5a is formed, and the through hole 5a is perpendicular to the longitudinal direction of the earth retaining member 1 in a state where the earth retaining member 1 is connected. It is penetrated in the vertical direction. Then, by inserting the through-hole 5 a into the pile 2, the earth retaining member 1 is fixed along the periphery of the site 20.
[0014]
Since the cross-sectional shape perpendicular to the longitudinal direction of the retaining member 1 is substantially C-shaped, the connecting members 3 and 5 can be fitted to the retaining member 1, and The projecting pieces 3b and 5b for fixing 1 to the pile 2 can be provided on the side of the opening 1a of the retaining member 1 having a substantially C-shaped cross section.
[0015]

Then, the ends of the earth retaining members 1 adjacent to each other in the longitudinal direction are inserted into the openings 6 a having the H-shaped cross section, whereby the earth retaining members 1 are fixed along the periphery of the site 20. The width 6b of the opening 6a is substantially equal to the thickness T of the retaining member 1 so that the fixing can be performed.
[0016]
FIG. 5 shows a fourth example of the embodiment of the present invention.
In the fourth example, the earth retaining member 1 is formed with a through hole 1b penetrating in the height direction perpendicular to the longitudinal direction. The number of the through holes 1b is preferably plural. Then, the ends of the earth retaining members 1 adjacent to each other in the longitudinal direction are respectively brought into contact with each other, and the pile 7 is inserted into the through hole 1b and driven into the site 20, so that the earth retaining member 1 is located on the periphery of the site 20. Fixed along. In this case, since the pile 7 is driven into the position where the earth retaining member 1 is fixed, it is not necessary to secure a place for driving the pile 7. Note that a reinforcing bar may be used as the pile 7. Further, the presence or absence of the connecting member for connecting the earth retaining member 1 is not limited.
[0017]
In this manner, the earth retaining member 1 is fixed along the periphery of the site 20 before the home building, thereby preventing earth and sand on the site 20 from flowing out into the surrounding gutter 24, the road 25, and the like. However, when the site 20 is raised, the earth retaining member 1 may not be able to sufficiently prevent the outflow of soil and the like at the site 20 with one step. Therefore, in this case, the retaining members 1 are stacked in a plurality of stages, and the retaining members 1 are fixed by increasing the height. This example is shown in FIG. 6 as a fifth example. In the fifth example, the case where the above-described connecting member 5 is used and the earth retaining member 1 is stacked in three stages is shown as a representative.
[0018]
As shown in FIG. 6, when the earth retaining member 1 is stacked in a plurality of stages, the pile 2 is driven so that the projecting height of the pile 2 becomes a height corresponding to the number of stages of the earth retaining member 1, and thereafter, The earth retaining members 1 adjacent to each other in the longitudinal direction of each stage are connected by the connecting member 5, and the through holes 5 a of the connecting members 5 of each stage are sequentially inserted into the piles 2, and the earth retaining members 1 are stacked in a plurality of stages. .
[0019]
Similarly, when the connecting member 3 shown in FIG. 2 is used, when the pile 6 having the H-shaped cross section shown in FIG. 4 is used, and when the pile 7 shown in FIG. The piles 2, 6, and 7 are driven in such a manner that the projecting height of the retaining members 1 becomes the height corresponding to the number of steps of the retaining member 1, and the retaining members 1 are stacked in a plurality of steps.
[0020]
As described above, the earth retaining member 1 has a substantially C-shaped cross section perpendicular to the longitudinal direction, so that strength can be obtained even when the thickness of the earth retaining member 1 is reduced. And the size is appropriate, so that it is excellent in transportability, workability, and the like. Also, since the substantially C-shaped opening 1a is directed toward the inside of the site 20, and the opposite flat portion is directed toward the outside of the site 20, the appearance from the outside of the site 20 is good. Improves the impression of the construction site. Furthermore, when a company name, a product name, or the like is displayed on the plane portion, the earth retaining member 1 also has an advertising effect.
