本発明は、造成地等の擁壁部、或いは土手、
提、崖部等における土砂崩壊を防止するための土
止工法に関する。[Detailed description of the invention] The present invention provides a retaining wall section or an embankment of a developed land, etc.
This article relates to earthwork methods for preventing landslides at cliffs, etc.

危険性が大であつた。 Conventionally, when constructing land, etc., it is common to simply plant grass and trees on slopes, which poses the risk of landslides during heavy rain, especially if the roots of the plants do not fully grow. The risk was great until the plant's roots were fully developed (it takes 2 to 3 years for a plant's roots to fully develop).
また、従来の他に土止工法として、法面をコン

土砂崩壊に直結する原因となる。 In addition to the conventional method, there is also a method of covering the slope with concrete blocks, etc., but this method is complicated to construct, and the entire slope is covered with concrete, and the slope is covered with concrete. Since the roots of plants such as trees and plants are not used, this destroys nature and at the same time deteriorates the environment.Furthermore, this earth mooring method allows water to escape to appropriate locations on the blocks covering the slope. Although pipes have been installed, the slope is almost completely blocked off by blocks, which limits the escape route for rainwater within the embankment layer. As a result, rainwater pools occur within the embankment layer. Since this accumulated rainwater has no escape route, the area gradually swells, and when it reaches the permissible limit, the accumulated rainwater flows out all at once in search of weak spots in the ground, which causes immediate landslides. It is a cause that is directly connected to.

Next, the engagement piece 3 is engaged with the engagement recess 7 of the engagement platform wall 6 to align the construction member a with the slope 16, and in this state, the fixing nail member c is inserted into the soil through the nail holes 4 and 8. Drive it in to connect and secure it. Next, the engagement piece 3 is engaged with the engagement recess 7 of the engagement table wall 6 to align the construction member a with the slope 16, so that an equilateral triangle is formed with the construction member a arranged horizontally. At this time, each construction member a is attached to the slope so that the rising wall 2 is located inside the triangle. This is the upper surface 1a of the square rod-shaped body 1 and the rising wall 2.
This is to form a rainwater conveyance path with the inner wall surface 2a of the triangle, and if the rising wall 2 is located at the outer edge of the triangle, it becomes impossible to form a rainwater conveyance path. Next, a joint member b is arranged at the intersection point (triangular apex) of each construction member a, and the engagement piece 3 of the construction member a arranged in a triangular shape is inserted into the engagement recess of the engagement base wall 6 of the joint member b. 7 and drive the nail member c into the soil through the nail holes 4 and 8 to fix the construction member a together with the joint member b. Next, the construction members a are arranged horizontally in a line with the rising wall 2 on the lower side, and the engagement pieces 3 are engaged with the engagement recesses 7 in the same manner as described above, and in this state, the nail members c are inserted into the nail holes 4. , 8 to fix the construction member a together with the joint member b. After the above-mentioned work, the slope is embanked to a height that almost coincides with the upper surface of the rectangular rod-shaped body 1 of each construction member a.
a is completed. Next, as shown in Fig. 15, the slope 16 above the earthen block 17a is leveled by removing 18 a predetermined depth, and then the soil layer reinforcing member e is laid on this level ground 19. The first earthen layer 20a is formed, and the slope side edge of the earth layer reinforcement member e (the part indicated by reference numeral 14a or 14b in FIG. 7) is connected to the upper construction member a (lateral direction As shown in detail in FIG. 12, the upper surface 1a of the rectangular rod-shaped body 1 of the construction member disposed in Nail member c is passed through the nail holes 4 and 8 of construction member a and joint member b.
is driven into the soil to fix the slope side edge of the soil layer reinforcing member e to the construction member a.
次いで、上記第１土止層２０ａの上面に適当に
盛土して前記除去１８前の状態に修復する。 Next, the top surface of the first earthen layer 20a is appropriately filled with earth to restore it to the state before the removal 18.

該実施例によれば、法面には構築部材ａの角形
棒状体１の上面に立上り壁２の内側壁面２ａとに
よる連通した雨水輸導路が構成してあるので、雨
水は該輸導路に沿つて流下し、各ジヨイント部に
おいて、緩衝壁９に衝突して流れの速度が緩和さ
れると共に流路が適当に分岐して変えられ、輸導
路を通つて良好に流下する。また、土層内の雨水
は法面側に流出し、上記と同様に輸導路を通つて
流下する。 According to this embodiment, since a rainwater conveyance path is formed on the slope, the upper surface of the rectangular rod-shaped body 1 of the construction member a communicates with the inner wall surface 2a of the rising wall 2. At each joint, the fluid collides with the buffer wall 9 to reduce the speed of the flow, and the flow path is appropriately branched and changed, allowing the fluid to smoothly flow down through the conveyance path. In addition, rainwater within the soil layer flows out to the slope side and flows down through the conveyance path in the same way as above.

ることができる。 In addition, earth and sand are bitten into the mesh 15 of the soil layer reinforcing member e by earth pressure, and the soil layer reinforcing member and the earth and sand layer are integrated, and the earth and sand are firmly held, and rainwater is transported by the soil layer reinforcing member. Since it is led out to the slope side through the guiding groove 13, landslides and landslides can be prevented.
本発明に係る土止工法は以上説明したとおりで
あるから本発明によれば次のような効果を期待す

部材の法面側縁部を構築部材に固定してあるの
で、構築部材は法面に確実かつ堅牢に保持さ
れ、押し流されるのを防止することができる。(b) Merely attaching construction members to the slope of the earthwork has problems with the stability of the construction members. Since the side edges are fixed to the construction member, the construction member can be held securely and firmly on the slope and can be prevented from being swept away.
(ロ) 法面はコンクリート製の構築部材により保護
され、雨水は構築部材の雨水輸導路に案内され
て流下するので法面の土砂の流出を防止でき、
したがつて、構築当初より大雨に充分耐え得る
擁壁等を得ることができる。(b) The slope is protected by concrete construction members, and rainwater is guided to the rainwater conveyance path of the construction members and flows down, which prevents soil from flowing out of the slope.
Therefore, it is possible to obtain a retaining wall etc. that can sufficiently withstand heavy rain from the beginning of construction.
(ハ) 雨水輸導路中には部分部（各連結部）に緩衝
壁が介在してあるので、輸導路中を流下する雨

とができる。この場合、雨水輸導路中に緩衝壁
が存在しないと、雨水の流れが急速になつて、
輸導路から法面上に溢ふれて法面の土砂を流出
する恐れがある。(c) Since buffer walls are interposed in the rainwater conveyance channel at each section (each connection section), rainwater flowing down the rainwater channel hits each buffer wall and its flow rate is weakened. Since the flow is diverted and flows downward while changing the flow path, it is possible to better prevent earth and sand from flowing out on the slope. In this case, if there is no buffer wall in the rainwater channel, the flow of rainwater will become rapid.
There is a risk that the soil will overflow from the transport route onto the slope and wash away the soil on the slope.
(ニ) 雨水は盛土層内に貯溜することなく、土層補
強部材に案内されて法面側に導出されるので盛
土層を安定して保護でき、土砂の押し流しや地
滑りを防止することができる。(d) Rainwater is guided by soil reinforcement members and directed to the slope side without accumulating in the embankment layer, so the embankment layer can be stably protected and earth and sand washed away and landslides can be prevented. .
(ホ) 法面には三角状に地はだが露呈しているの
で、該部に芝等を植付けすることができ、この
芝等の根が張つていくことにより法面の保護を
さらに強固にすることができる。(e) Since the slope has exposed triangular strips of ground, it is possible to plant grass, etc. in this area, and as the roots of this grass spread out, the protection of the slope is further strengthened. can do.
(ヘ) 自然を破壊したり環境を害することを極力防
