2. Description of the Related Art Conventionally, earth retaining methods applied to slopes on which roads, hillsides, river revetments, etc. are predicted to have landslides or collapsed slopes have been used for concrete or concrete blocks or boxes made of steel or wire mesh. The mainstream is one in which cobblestone is put into a formwork, and in recent years, a steep reinforced embankment method has also become widespread.

[0003] On the other hand, in recent years, civil materials and construction methods which emphasize natural environment and landscape and are environmentally friendly are being developed, and there is a strong demand for the adoption of a method of actively using natural materials such as natural stone and wood. Has begun. In particular, the promotion of thinning is an urgent issue in order to cultivate domestic forests in a healthy manner, and the active use of thinned timber not only in the construction field but also in civil engineering materials is the biggest concern of stakeholders. .

Conventionally, a slope protection method using wood has been adopted as a simple fence work on a hillside such as a road slope or a mountainside construction work. In addition, for example, Japanese Patent Application Laid-Open No. H10-114951.
As described in Japanese Unexamined Patent Application Publication No. 2000-83833 or Japanese Patent Application Laid-Open No. 2000-8383, the use of wood alone or a combination of wood and a foreign material to increase the number of cases that are used as earth retaining works or seawalls that resist backside earth and sand is increasing. .

FIG. 17 is a perspective view of a state in which the frame 7a is folded and the reinforcing net is omitted.

Next, the operation and effect of the retaining member of this embodiment will be described. By applying the retaining member 7, even if the wood 11 rots, there is no outflow of the back soil,
It is free from the problem of ensuring safety by using wood, and it is now possible to use wood also in the surrounding areas of houses and the retaining structures on road slopes, where use has been refrained from before.

Further, since the decay of wood does not affect the structure, it is not necessary to inject expensive preservatives into the wood to increase its useful life. Timber can be used without considering the effect of the timber.

Further, since a space is provided between the wood portion and the retaining portion, the wood does not come into direct contact with the back soil and has the effect of improving the durability of the wood. Since this space can be used as a hideout for small animals, environmentally friendly materials and seawall protection can be provided.

In the conventional retaining structure using wood, when the wood is decayed and there is a concern about the outflow of the back sediment,
Reconstruction and associated costs were required. In contrast,
In the retaining member 7 using the wood panel 1, the wood part 1 can be easily attached and detached, and when the wood rots, the wood part can be replaced by replacing only the wood part. By repeating this renewal up to the useful life of the support frame and the reinforcing net, the workability and maintenance efficiency are greatly improved as compared with the conventional products, resulting in a very excellent cost-effectiveness.

FIGS. 18 and 19 show a ninth embodiment of the present invention. When applying the retaining member to the site, it is necessary to take measures in the curved section of the inner curve with the overlap of the back part. In the present embodiment, as shown in FIG.
The support frame 7b includes a vertical column member 24 and a leg member 72 on the right front side.
And the stopper 71 are moved to the center. This provides a space at the right end. Further, the right side of the plate member 73 is extended outside the leg member 72. Note that FIG.
In the description, the wood part and the reinforcing net are omitted.

Referring to the plan view of the curved section shown in FIG. 19, in the support frame 7b, the left rear part of the support frame 7b adjacent to the right side by the space distance 79 between the front right end and the leg member 72a is positioned inside. Can be arranged.
Further, the left leg member 72 of the support frame 7b adjacent to the right is placed on the plate member 73 of the support frame 7b adjacent to the left, so that the weight of the support frame 7b adjacent to the right including the back soil is reduced to the left. Support frame 7 adjacent to
In addition, the self-standing stability can be increased. It is desirable that the adjacent left and right support frames 7b fix the vertical column members 24 and the leg members 72a with the long bolts 78 or the like.

FIG. 20 shows a tenth embodiment of the present invention. FIG. 20 facilitates stacking when applied to a cut slope or an embankment slope having a height of about 3 m which does not require a relatively high height. In FIG. 20, the wood part and the reinforcing net are omitted.

When the earth retaining members 7 are stacked alone, there is a possibility that overturning or sliding may occur in safety calculation of the earth pressure on the back surface. In such a case, a welding wire mesh or a grid-like iron mesh 80 is arranged on the back surface of the support frame 7a, and both ends of the support frame 7a are formed into a hook-shaped reinforcing bar 81.
a and the iron nets 80 are connected. As a result, the retaining member 7a having a substantially L-shaped cross section is changed to a box-shaped cage. If the filling soil 75 is rolled, the support frames 7a can be stacked.

According to the timber panel, the retaining member and the timber fixing method according to the present invention, even if the timber on the scenery rots, the back soil can be prevented from flowing out. It can be easily replaced in units.

According to the timber panel, the retaining member and the timber fixing method according to the present invention, since natural materials such as timber or bamboo are used, consideration is given to the environment which is currently regarded as important. In places where people can see, there is an effect of providing an excellent landscape. In addition, on the road slope, it is a landscape construction method that also saves the time and effort to cut out weeds and secures the viewing distance.

Further, the use of thinned wood for wood has the effect of promoting thinning, which is a common problem for mountain villages nationwide. Since it is not necessary to perform preservative treatment on the used wood, exchanging the decayed material in a relatively fast cycle has an effect of generating a demand for thinned wood again.
