Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simple earth retaining fence, and particularly to an earth retaining fence that can be easily assembled at a construction site.

When there is a risk of river flooding or levee failure, urgent and temporary flood prevention methods are required.

This is a typical case, but in other cases where temporary construction of a fence is required, a fence that can be easily assembled and cast at the construction site is required.

The inventor first provided a plurality of notch lines parallel to the sides of a steel plate, etc., alternately extruded the narrow portions formed by the notch lines to form an opening, and inserted a support into this opening. We proposed an earthen fence that would be poured into the construction area.

(Japanese Patent Publication No. 47-45301) This retaining board is convenient for transportation and storage, and can be connected by simply stacking the above openings and inserting stakes through them, making assembly and implementation easy and yielding great results. was completed.

However, the size of the opening is fixed, and thicker stakes cannot be used.

When a large force is applied, there have been cases where the opening is torn from the end of the score line.

If the thickness of the pile is thin, there is a risk that the steel plate will be pulled out of the pile when an upward force is applied.

Parts of the pillars are exposed on the surface, so if the pillars are driven unevenly, the piles will be unbalanced and will spoil the aesthetics.

Since a single steel plate protrudes from the edge of the fence, it is often deformed by the external force of installation waves.

There were problems such as high cost due to opening formation.

This invention eliminates the above-mentioned drawbacks by drilling bolt holes at regular intervals parallel to the sides of the retaining board, fixing the heavily stressed parts of the board with bolts, and press-fitting piles between the bolts. This is an attempt to obtain a retaining fence.

A detailed explanation will be given below with reference to the drawings.

As shown in Fig. 1, the fence plate which is the main body of the earth retaining fence of this invention is made of a thin metal such as a steel plate or a rectangular plate made of plastic, with bolt holes 1, 2, 3...1' parallel to the sides. .

2', 3', etc. are provided.

This fence board is used as follows.

In the middle of the fence, overlap the ends of the two fence boards and
If the stakes 6 are thin, match the first and second bolt holes from the edge of the fence board and tighten with bolts 4, as shown in Figures 5 and 3. Press-fit the pile 6 as shown.

The fence board thereby bulges out and elastically holds the stake 6 from both sides.

During emergency construction, it is not possible to collect piles of the same thickness, so if the piles are thick, bolt holes 1 and 3' or 3 and 1' together, rather than adjacent bolt holes. This allows you to use up to twice the thickness of the stake.

At the end of the fence, as shown in Figure 6, bend the end of the fence board, align bolt holes 1 with appropriate bolt holes, tighten the bolts, and press-fit stakes 6 into the resulting annular part 7 in the same way. do.

FIG. 8 shows a perspective view of the fence constructed as described above.

The fence thus assembled to the required length is erected as shown in FIG. 9, the stakes 6 are driven into the ground, and earth and sand 8 are filled behind them to complete the earth retaining fence.

Since the earth retaining fence of the present invention has the above-mentioned configuration, (1) it is convenient for transportation and storage, and can be easily assembled at the construction site.

■ The flat parts of the fence boards are overlapped and the stakes are press-fitted into the bolted parts, so even if the stakes are thin, the boards deform by the required amount and tighten the stakes with their elasticity.

■ Since multiple bolt holes can be selected, overlapped, and bolted, the size of the pile insertion part can be freely selected depending on the thickness of the pile.

■ Processing to the fence board can reduce additional cost by simply providing bolt holes.

■ There are no cut lines on the board, so problems such as the board tearing are unlikely to occur even if force is applied.

■ The ends of the fence are annular and the stakes are located at the extreme ends, so deformation due to external forces is less likely to occur.

■ Since the stakes are inserted through the inside of the overlapping fence boards, they do not show up on the outside, and even if the stakes are loose, they do not spoil the aesthetics (and strengthen the tension).

It has many remarkable effects such as:
