Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to an earth retaining fence.

[Prior art]

Traditionally, earth retaining fences have been used to green mountainsides, prevent disasters, and provide long-term stable nature protection.

However, conventional earth retaining fences have not been structurally strong enough to easily collapse due to landslides, and have also lacked safety during planting operations.

Furthermore, it was not easy to install earth retaining fences because the installation location was on a mountainside and the members were large.

[Purpose of invention]

The present invention was developed in view of the conventional problems mentioned above, and its purpose is to propose an earth retaining fence that has sufficient strength, can be installed firmly and stably, and is easy to install. There is a particular thing.

〔Example〕

Next, embodiments of the present invention will be described.

The earth retaining fence according to the present invention can be roughly divided into a main pillar part and an earth retaining part.

In terms of the drawing, the main column is the part composed of the main column 1, the horizontal members 3, the bottom plate 4, the diagonal members 5, and the anchors 6, and the frame horizontal members 7, frame vertical members 8, and 9, The portion constituted by the reinforcing material 10 and the expanded metal 11 is the earth retaining portion.

First, the configuration of the main pillar part will be explained based on the drawings.
In the figures and FIG. 3, an angle cross member 3 is attached by welding to a position where the leg portion 13 remains on the main pillar member 1 made of an angle.

Further, the upper end of the main pillar member 1 and the rear part of the cross member 3 are welded together by the diagonal member 5 to form a joint triangular part.

A hole through which the anchor 6 passes is provided at the rear of the cross member 3, and the head of the anchor 6 is prevented from slipping out.

The bottom plate 4 is a rigid plate of an appropriate length, processed as shown in FIG. 4, and attached to the rear of the cross member 3 with bolts.

The above is the configuration of the main pillar section.

Next, the configuration of the earth retaining section will be explained based on FIG. 2.

In FIG. 2A, a frame member 7 made of angles and a frame vertical member 8 are welded to form a frame body.

A reinforcing material 10 is welded to the center of the back of the frame, and an expanded metal 11 is spot-welded to the back of the frame.

In addition, as shown in the side view of the frame body in FIG. 2B, the frame vertical members 8
The frame vertical members 9 are welded and reinforced to the frame structural members 7 so that the extended metal 11 is sandwiched and crimped on the back side at the position.

Now, in the earth retaining fence according to the present invention, the parts of the frame vertical members 8 on both sides of the earth retaining part configured as described above are connected to the main pillar member 1 of the main pillar part by bolts 12, and the whole is connected. Constructed as.

In addition, when the earth retaining fence explained above is further connected to the left and right to extend it, as shown in Figs. It is attached by welding, and the frame vertical member 8 of the retaining portion is bolted and attached to the main pillar member 2 with a stop bolt 12.

Needless to say, the main pillar section is bolted to the other side of the earth retaining section installed in this way.

In the above case, installation is facilitated by attaching the main pillars 2 to the main pillars 1 in advance according to the number of earth retaining parts to be connected.

Further, during actual installation, the length of the anchor 6 shall be changed depending on the nature of the ground at the installation location.

Next, a method for installing an earth retaining fence according to an embodiment of the present invention will be explained.

First, after the rough cutting is completed, a bed is excavated to install an earth retaining fence on the slope.

The excavation slope ratio in bed excavation shall be 1:0.3.

The leg part 13 of the main pillar material 1 is embedded in the floor, the main pillar part is installed on the floor, the anchor 6 is driven in and fixed, and the frame vertical member 8 of the earth retaining part is bolted to the main pillar material 1 of the main pillar part.

Furthermore, the main pillar part is attached to the frame vertical member 8 on the other side of the earth retaining part and fixed with an anchor 6.

By driving the anchors 6, the cross member 3 is firmly fixed to the floor.

Next, the bottom plate 4 is attached to the main pillar portion at a predetermined position of the cross member 3, and the top of the cross member 3 and the bottom plate 4 are covered with earth and sand.

As a result, the weight of the soil is applied to the cross members 3 and the bottom plate 4, allowing for a strong installation.

Then, the vegetation sandbag is attached to the expander metal 11 on the back side of the earth retaining part with a binding wire, and finally the vegetation sand bag is attached to the front of the earth retaining fence, and the front surface of the earth retaining fence is painted green or the like.

According to the earth retaining fence according to this embodiment which is constructed and used as described above, since the main pillar part has a triangular shape, a structure with high mechanical strength can be obtained, and the anchor 6 and the Since the bottom plate 4 is provided, strong and stable installation can be performed.

Therefore, compared to conventional retaining fences, the structure can be maintained semi-permanently, and it is also extremely safe to carry out planting work on top of the retaining fences.

Furthermore, since the structure is divided into the main pillar part and the earth retaining part,
Once each part has been transported to the installation location, all that is left to do is bolt it on and the installation work can be done easily.

[Effect of idea]

As described above, according to the present invention, sufficient mechanical strength can be obtained since the main pillar portion is triangular in shape.

Also, during installation, the legs 13 of the main pillar 1 are embedded and the anchors of the cross members 3 are driven in, and the cross members 3 and 3 are
By pouring soil on top of the bottom plate 4 provided on the bottom plate 4, the weight of the soil is sufficiently applied, so that extremely stable and strong installation is possible.

Therefore, the structure can be maintained semi-permanently, and it is extremely safe to perform planting work on the earth retaining fence.

In addition, since the main pillar part, earth retaining part, and bottom plate are each removable with bolts, they can be transported to the installation site in a detached state and easily assembled on the spot, making the installation work extremely easy.
