Description
本考案は、土擁壁に関し、特にコンクリート・ブロックの代用として利用できる土擁壁に関する。 The present invention relates to a retaining wall, and more particularly to a retaining wall that can be used as a substitute for a concrete block.
従来、盛土構造物において、板状ブロックの壁面材を使用し、上下ブロックの間には継手金具及びスライド式ジョイントを設け、且つ補強土中に埋め込んだアンカー部材とスライド式ジョイントを連結する構成は公知である（特許文献１参照）。 Conventionally, in the embankment structure, using a wall material of a plate-like block, providing a joint fitting and a slide joint between the upper and lower blocks, and connecting the anchor member embedded in the reinforcing soil and the slide joint. It is known (see Patent Document 1).
又、駐車場や工場等の敷地造成地の擁壁、土捨て場の擁壁、その他各種の用途に利用される補強土擁壁において、壁面材をエキスパンドメタル（網状の鋼製部材）を利用して施工する構成は知られている（特許文献２参照）。
従来の壁面材としてコンクリートを用いた土擁壁は、施工できれば、見栄えもよいのであるが、コンクリートの擁壁は重量が重く、その搬送や施工作業に重機が必要であり、街中の狭小な場所で施工するような場合は作業が困難であるという問題がある。 A conventional earth retaining wall using concrete as a wall material looks good if it can be constructed, but concrete retaining walls are heavy and heavy equipment is required for their transport and construction work. However, there is a problem that the work is difficult when the work is carried out by using the above method.
従来の壁面材としてエキスパンドメタルを利用する補強土擁壁は、コンクリートの擁壁よりは軽いが、エキスパンドメタルは、鋼板をカッターで切って製造するので角が鋭角になり、鋏の刃のようになっており、又エキスパンドメタルの端部は菱形のとがった部分が残る。その結果、搬送や土擁壁の施工の際に怪我をしたりしやすく、取り扱いが簡単ではないという問題があった。 Reinforced earth retaining walls that use expanded metal as a conventional wall material are lighter than concrete retaining walls, but expanded metal is manufactured by cutting steel plates with a cutter, so the corners are sharp, like scissor blades. The expanded metal has a diamond-shaped point on the end. As a result, there is a problem that injuries are likely to occur during transportation and construction of the retaining wall, and handling is not easy.
さらに、エキスパンドメタルを利用する補強土擁壁は、その施工において、複数の壁面材を積み上げていく際に、上位の段の壁面材が下位の段の壁面材に接触して、上段の盛土の沈下による重量が下段の壁面材にかかり、盛土の沈下に対する壁面材の伸縮量が小さく、盛土の沈下が集約される最下段の壁面材に上方の盛土の沈下重量がかかると、特に最下段の壁面材は変形や座屈による破損が発生する。 In addition, in the construction of a reinforced soil retaining wall using expanded metal, when stacking multiple wall materials, the wall material of the upper stage contacts the wall material of the lower stage, and If the weight of the embankment is applied to the lower wall material, the amount of expansion and contraction of the wall material with respect to the settlement of the embankment is small, and the settlement weight of the upper embankment is applied to the lower wall material where the settlement of the embankment is concentrated, The wall material is damaged by deformation or buckling.
本考案は、従来技術の上記のような問題の生じない土擁壁を実現することを目的とするものであり、特に、市街地等の狭小地でも施工可能なコンクリートブロック等の代用として、簡単、短期工程で、且つ安全に施工でき、しかも資材の搬送に重機等を必要としない土擁壁を実現することを課題とする。 The present invention aims at realizing an earth retaining wall which does not cause the above-mentioned problems of the prior art, and is particularly simple as a substitute for a concrete block that can be constructed even on a narrow land such as an urban area. It is an object of the present invention to realize a retaining wall that can be constructed safely in a short-term process and that does not require heavy equipment or the like to transport materials.
本考案は上記課題を解決するために、底面地盤上に盛土構造体を複数段積み重ねて形成される土擁壁であって、前記複数段の盛土構造体のそれぞれは、横線と縦線の交点が溶接されて成る餅網から形成され且つ壁面部と底面部を有する餅網Ｌ型ユニットを備え、前記餅網Ｌ型ユニット上に盛土が盛られて構成されていることを特徴とする土擁壁を提供する。 In order to solve the above problems, the present invention is an earth retaining wall formed by stacking a plurality of embankment structures on a bottom ground, each of the plurality of embankment structures being an intersection of a horizontal line and a vertical line. Characterized by comprising a rice cake L-shaped unit formed from a rice cake net formed by welding and having a wall surface portion and a bottom portion, and embankment is laid on the rice cake L-type unit. Provide a wall.
前記壁面部の上端には横線が配置されておらず、前記壁面部の上端の縦線は、上位の盛土構造体の餅網Ｌ型ユニットの下端の横線の内側に配置されている構成としてもよい。 No horizontal line is arranged at the upper end of the wall portion, and the vertical line at the upper end of the wall portion may be arranged inside the horizontal line at the lower end of the rice cake L-shaped unit of the upper embankment structure. Good.
前記壁面部は、その上端が該壁面部の上位の壁面部の餅網の内側に入るように、角度が付けられていることが好ましい。 The wall portion is preferably angled so that the upper end of the wall portion enters the inside of the rice cake net on the upper wall portion of the wall portion.
前記壁面部の底面部からの高さは０．２〜０．３ｍであることが好ましい。 The height of the wall surface from the bottom surface is preferably 0.2 to 0.3 m.
前記餅網Ｌ型ユニットの横幅は、０．６〜２．０ｍであることが好ましい。 It is preferable that the width of the rice cake L-shaped unit is 0.6 to 2.0 m.
本考案に係る土擁壁は、次のような効果が生じる。
（１）本考案で用いる餅網Ｌ型ユニットは、従来の補強土擁壁に用いる補強部材に比べると、幅が１〜２ｍで、高さ（壁面部の高さ）もほぼ０．３ｍ程度のコンパクトな構造をしているから、その運搬に重機等も不要であり、施工等における取り扱いがきわめて容易で、施工場所も狭くても済む。そして、コンクリート・ブロックのように重くないので、基礎が不要である。
The earth retaining wall according to the present invention has the following effects.
(1) The mochi net L-type unit used in the present invention has a width of 1 to 2 m and a height (height of a wall portion) of about 0.3 m, as compared with a reinforcing member used for a conventional reinforcing soil retaining wall. Because of its compact structure, no heavy equipment or the like is required for its transportation, handling in construction and the like is extremely easy, and the construction site can be small. And because it is not as heavy as a concrete block, no foundation is needed.
（２）特に、１段の盛土構造体の高さは、０．３ｍ程度であり、従来の盛土構造体の高さ（０．６ｍ以上）に比べるとかなり低いので、各段の盛土構造体における壁面部にかかる土圧が１／４以下となるので、餅網Ｌ型ユニット強度はそれほど大きくなくても、その壁面部が変位、変形することがない。従って、従来の補強土擁壁等で利用していた壁面部と底面部を斜めタイ材で結合するような構成が不要となり、全体の構成、工程が簡単となり、コストの低減が可能である。 (2) In particular, the height of the one-stage embankment structure is about 0.3 m, which is considerably lower than the height of the conventional embankment structure (0.6 m or more). , The earth pressure applied to the wall portion becomes 1/4 or less, so that the wall portion is not displaced or deformed even if the strength of the L-shaped unit is not so large. Therefore, a structure in which the wall surface and the bottom surface used in the conventional reinforcing soil retaining wall and the like are joined by an oblique tie material is not required, and the entire structure and process are simplified, and the cost can be reduced.
（３）従来の土擁壁の際に必要であった、敷網材（各段の盛土の上に敷設し、盛土間の剪断力を強めるとともに、壁面材等をタイ材で引っ張る役割をする。）が不要であり、施工が簡単となり、工期が短縮化可能である。 (3) Laying net material (layed on the embankment of each step, strengthening the shearing force between the embankments, and pulling the wall material, etc. with a tie material, which was necessary for the conventional retaining wall ) Is unnecessary, construction is simple, and the construction period can be shortened.
（４）本考案の土擁壁では、餅網Ｌ型ユニットの上端には横線が設けられていないので、上段の餅網Ｌ型ユニットがその上に盛土が盛られた際に盛土とともに下方に沈み込んでも、下段の餅網Ｌ型ユニットの横線に接触して阻止されることがないので、餅網Ｌ型ユニット、特に最下段の餅網Ｌ型ユニットの損傷等が防止でき、耐久性が向上する。 (4) In the earth retaining wall of the present invention, since no horizontal line is provided at the upper end of the rice cake L-shaped unit, the upper rice cake net L-shaped unit is placed together with the embankment when the embankment is laid thereon. Even if it sinks, it does not come in contact with the horizontal line of the lower rice cake net L-type unit, so that it is possible to prevent damage to the rice cake net L-type unit, especially the lowermost rice cake net L-type unit, and to improve durability. improves.
（５）餅網Ｌ型ユニットの餅網は、その縦線と横線の交点が溶接され丸みを帯びており、従来、土擁壁の補強に使用されているエキスパンダメタルのように、鋭角となった部分がないので、人が接触しても、怪我などの生じる危険がない。 (5) The rice cake net of the L-shaped unit is rounded at the intersection of the vertical and horizontal lines, and has an acute angle like an expander metal conventionally used for reinforcing a retaining wall. Since there is no broken part, there is no danger of injuries and the like even if people come into contact.
本考案に係る土擁壁を実施するための最良の形態を実施例に基づいて図面を参照して説明する。 The best mode for carrying out the earth retaining wall according to the present invention will be described based on an embodiment with reference to the drawings.
図１は、本考案に係る土擁壁１の断面構造を説明する図である。この土擁壁１は、餅網Ｌ型ユニット２（「ワイヤメッシュＬ型ユニット」とも言う。）を複数段積み重ね、その内面側に植生マット３を配置して、その各段に盛土４を盛って成る構造物である。換言すれば、餅網Ｌ型ユニット２に盛土４を盛った盛土構造体５を複数段積み重ねて成る構造物である。なお、植生マット３とともに、或いは植生マット３に代えて吸い出し防止材を配置してもよい。 FIG. 1 is a diagram illustrating a cross-sectional structure of the earth retaining wall 1 according to the present invention. This retaining wall 1 is composed of a plurality of stacked rice cake L-shaped units 2 (also referred to as “wire mesh L-shaped units”), a vegetation mat 3 disposed on the inner surface thereof, and an embankment 4 piled on each step. It is a structure consisting of In other words, the structure is formed by stacking a plurality of embankment structures 5 each having the embankment 4 laid on the rice cake net L-shaped unit 2. In addition, you may arrange | position a suction prevention material with the vegetation mat 3 or in place of the vegetation mat 3.
図２は、餅網Ｌ型ユニット２の構成を説明する図であり、（ａ）、（ｂ）、（ｃ）は、それぞれ正面図、側面図、平面図である。図２（ａ）〜（ｃ）に示すように、餅網Ｌ型ユニット２は、やや太い番線を縦横に直角に置き（以下、縦に置かれた番線を「縦線」と言い、横に置かれた番線を「横線」という。）、交点を溶接して成る餅網（餅を焼く網であり、「ワイヤメッシュ」とも言う。）から形成されている。 2A and 2B are diagrams illustrating the configuration of the rice cake L-shaped unit 2, and FIGS. 2A, 2B, and 2C are a front view, a side view, and a plan view, respectively. As shown in FIGS. 2 (a) to 2 (c), the rice cake net L-shaped unit 2 puts a slightly thick number line vertically and horizontally at right angles (hereinafter, a number line placed vertically is referred to as a “vertical line”, and The placed line is called a "horizontal line"), and is formed from a rice cake net formed by welding intersections (a net for baking rice cake, also called a "wire mesh").
そして、餅網Ｌ型ユニット２は、正面の壁面部６と底面部７とから構成され、側方から見た形状はほぼＬ型をしている。餅網Ｌ型ユニット２の底面部７に対する壁面部６の折り返しの角度θは、土擁壁１の高さや環境を考慮して適宜、決めればよい。この角度θは、壁面部６が鉛直乃至ほぼ鉛直（鉛直面に対して５分程度）であってもよい。餅網Ｌ型ユニット２の餅網材料としては、溶融亜鉛メッキをした場合のように腐食に強い鉄鋼線材を使用する。 The rice cake L-shaped unit 2 is composed of a front wall surface portion 6 and a bottom surface portion 7, and is substantially L-shaped when viewed from the side. The turning angle θ of the wall surface portion 6 with respect to the bottom surface portion 7 of the rice cake net L-type unit 2 may be appropriately determined in consideration of the height of the retaining wall 1 and the environment. The angle θ may be vertical or almost vertical (about 5 minutes with respect to the vertical plane). As a rice cake net material of the rice cake net L-type unit 2, a steel wire rod that is resistant to corrosion as in the case of hot dip galvanization is used.
餅網Ｌ型ユニット２の壁面部６の高さ、即ち、１段の盛土構造体５の高さｈは、従来の壁面部６に比べて、かなり低い寸法である数種類の高さ寸法のもの、例えば、０．２〜０．３ｍ程度、を用意し、構築対象である土擁壁１の目的や設置環境に応じて適宜選択すればよい。本実施例では盛土構造体５の高さｈは、０．３ｍとする。餅網Ｌ型ユニット２の餅網の縦線８の太さ（断面直径）はφ１０ｍｍ程度であり、横線９の太さはφ６ｍｍ程度でもよい。 The height of the wall portion 6 of the rice cake net L-type unit 2, that is, the height h of the one-stage embankment structure 5, is considerably lower than that of the conventional wall portion 6 and has several different heights. For example, about 0.2 to 0.3 m may be prepared and appropriately selected according to the purpose and installation environment of the earth retaining wall 1 to be constructed. In this embodiment, the height h of the embankment structure 5 is 0.3 m. The thickness (cross-sectional diameter) of the vertical line 8 of the rice cake net L-type unit 2 may be about φ10 mm, and the thickness of the horizontal line 9 may be about φ6 mm.
餅網Ｌ型ユニット２は、その正面から見て横幅は、０．６〜２．０ｍであることが好ましい。横幅を狭くすると、壁面部を平面図図で全体的に見て曲線状に形成しやすいというメリットがある。縦線８のピッチ（隣接する縦線８相互の間隔）は、１０本／ｍ程度とする。横線９のピッチは、壁面部６と底面部７で異なる。即ち、壁面部６においては、植生マット３や吸い出し防止材をその内側に配置し支持するので、横線９のピッチを細かくする。なお、本考案の餅網Ｌ型ユニット２では、その壁面部６の上端１０では、横線９がない構造であることを特徴としている。 The breadth of the rice cake L-shaped unit 2 is preferably 0.6 to 2.0 m when viewed from the front. When the width is reduced, there is a merit that the wall portion can be easily formed into a curved shape when viewed in plan view as a whole. The pitch of the vertical lines 8 (the interval between adjacent vertical lines 8) is about 10 lines / m. The pitch of the horizontal line 9 differs between the wall surface portion 6 and the bottom surface portion 7. That is, since the vegetation mat 3 and the suction-preventing material are arranged and supported on the wall surface 6, the pitch of the horizontal lines 9 is reduced. In addition, the rice cake L-shaped unit 2 of the present invention is characterized in that the upper end 10 of the wall 6 has no horizontal line 9.
餅網Ｌ型ユニット２の底面部７の水平方向の長さは、壁面部６の高さに応じて、いくつかの種類の長さのものを用意して、構築する土擁壁１の規模や環境等を考慮して選択して使用すればよい。ちなみに、本実施例では、図１に示すように、底面部７の長いものと短いものを交互に積み重ねる構造としている。同じ長さのものを使用して積み重ねる場合もある。 The horizontal length of the bottom portion 7 of the rice cake L-shaped unit 2 depends on the height of the wall portion 6 and is prepared in several lengths, and the scale of the retaining wall 1 to be constructed. It may be selected and used in consideration of the environment and environment. Incidentally, in the present embodiment, as shown in FIG. 1, a structure in which long and short bottom portions 7 are alternately stacked. They may be stacked using the same length.
図３は、以上の構造の餅網Ｌ型ユニット２を積み重ねた餅網積み重ね構造１１を示す図である。図３（ａ）において餅網積み重ね構造１１の全体構成を示す。土擁壁１の横幅（正面から見て横方向の長さ）に応じて、各段において、複数の餅網Ｌ型ユニット２を横幅方向に複数個並べられている。 FIG. 3 is a diagram showing a rice cake net stacking structure 11 in which rice cake net L-type units 2 having the above structure are stacked. FIG. 3A shows the entire structure of the rice cake stacking structure 11. In each stage, a plurality of rice cake L-shaped units 2 are arranged in the width direction according to the width (length in the horizontal direction when viewed from the front) of the retaining wall 1.
餅網Ｌ型ユニット２の壁面部６の上端には横線９が設けられていない。換言すれば、壁面部６の最上位の横線９は、縦線８の上端から比較的下がった下方の位置に設けられている。そして、横線９は、図３（ｂ）に部分拡大図で示すように、下段の餅網Ｌ型ユニット２の縦線８の上端は（縦線８の上端は必要ならば少し内側に折り曲げて）、上段の餅網Ｌ型ユニット２の下端の横線９の内側に位置するように配置し、外側にとびださないように上段の餅網Ｌ型ユニット２の下端の横線９で押さえるような構成とする。 No horizontal line 9 is provided at the upper end of the wall portion 6 of the rice cake net L-shaped unit 2. In other words, the uppermost horizontal line 9 of the wall portion 6 is provided at a position relatively lower than the upper end of the vertical line 8. As shown in the partial enlarged view of FIG. 3B, the horizontal line 9 has the upper end of the vertical line 8 of the lower rice cake net L-type unit 2 (the upper end of the vertical line 8 is bent slightly inward if necessary. ), Placed so as to be located inside the horizontal line 9 at the lower end of the upper rice cake net L-type unit 2 and pressed down by the horizontal line 9 at the lower end of the upper rice cake net L-type unit 2 so as not to jump outside. Configuration.
このように下段の餅網Ｌ型ユニット２の壁面部６の上端には横線９が設けられていないので、上段の餅網Ｌ型ユニット２は、その上に盛土４が盛られた際に沈み込んでも自由に盛土４とともに下がることができ、下段の餅網Ｌ型ユニット２の壁面部６の横線９に接触し、阻止されることがないので、上下の段の餅網Ｌ型ユニット２のそれぞれの損傷等が防止できる。 As described above, since the horizontal line 9 is not provided at the upper end of the wall portion 6 of the lower rice cake net L-type unit 2, the upper rice cake net L-type unit 2 sinks when the embankment 4 is laid thereon. It can be freely lowered together with the embankment 4 even if it is put into contact with the horizontal line 9 of the wall portion 6 of the lower rice cake net L-type unit 2 and is not blocked. Each damage can be prevented.
図４は、本考案に係る土擁壁１の構造を示す斜視図であり、特に餅網積み重ね構造１１において、壁面部６の内側の面に植生マット３を配設した状態を示す図である。植生マット３は、各段落の餅網Ｌ型ユニット２の壁面部６の内面に張り付けられ、番線で壁面部６に結い付けられている。なお。図４（ａ）は、各段落の餅網Ｌ型ユニット２の間には盛土４が盛り込まれているが、この盛土４は省略している。 FIG. 4 is a perspective view showing the structure of the earth retaining wall 1 according to the present invention, in particular, a state in which the vegetation mat 3 is arranged on the inner surface of the wall portion 6 in the rice cake stacking structure 11. . The vegetation mat 3 is attached to the inner surface of the wall 6 of the rice cake L-shaped unit 2 of each paragraph, and is tied to the wall 6 by a number line. In addition. In FIG. 4A, the embankment 4 is embedded between the rice cake L-shaped units 2 of each paragraph, but the embankment 4 is omitted.
本考案に係る土擁壁１の施工に際しては、まず最下段の餅網Ｌ型ユニット２を、正面から見て所望の横方向の長さとなるように複数個、構築すべき場所の地盤１２上に並べて配置する。この場合、壁面部６と底面部７を斜めタイ材で結合するような構成が不要である。そして、餅網Ｌ型ユニット２の壁面部６の内側の面に図４に示すように植生マット３を張り付けて番線で結い付ける。この後、盛土４を盛って転圧し最下段の盛土構造体５を構築する。 When constructing the earth retaining wall 1 according to the present invention, first, a plurality of lowermost rice cake net L-type units 2 are formed on the ground 12 at a place to be constructed so as to have a desired lateral length when viewed from the front. Arrange them side by side. In this case, there is no need to provide a configuration in which the wall surface portion 6 and the bottom surface portion 7 are joined by oblique tie members. Then, the vegetation mat 3 is attached to the inner surface of the wall surface portion 6 of the rice cake net L-shaped unit 2 as shown in FIG. Thereafter, the embankment 4 is embanked and compacted to construct the lowermost embankment structure 5.
この最下段の盛土構造体５の上面に、２段目の餅網Ｌ型ユニット２を、最下段の場合と同様に土擁壁１の横幅方向に複数個並べて配置し、餅網Ｌ型ユニット２の壁面部６の内側の面に図４に示すように植生マット３を張り付けて番線で結い付ける。この後、盛土４を盛って転圧し２段目の盛土構造体５を構築する。以下、同様にして順次上段の盛土構造体５を形成する。 On the upper surface of the lowermost embankment structure 5, a plurality of second-stage mochi net L-shaped units 2 are arranged side by side in the width direction of the earth retaining wall 1 in the same manner as in the lowermost stage. The vegetation mat 3 is attached to the inner surface of the second wall 6 as shown in FIG. Thereafter, the embankment 4 is embanked and compacted to form a second-stage embankment structure 5. Hereinafter, similarly, the embankment structure 5 of the upper stage is sequentially formed.
以上、本考案に係る土擁壁を実施するための最良の形態を実施例に基づいて説明したが、本考案はこのような実施例に限定されるものではなく、実用新案登録請求の範囲に記載された技術的事項の範囲内でいろいろな実施例があることは言うまでもない。 As described above, the best mode for carrying out the earth retaining wall according to the present invention has been described based on the embodiment. However, the present invention is not limited to such an embodiment, and is described in the claims of the utility model registration. It goes without saying that there are various embodiments within the scope of the described technical matters.
以上のとおり、本考案に係る土擁壁は、餅網から成る餅網Ｌ型ユニットを盛土を盛りながら複数段積み上げることにより簡単に構築できるから、比較的施工場所が狭い市街地等の場所でも適用可能であり、街中で見かけるコンクリート・ブロック擁壁の代用の擁壁として好適である。さらに、本考案に係る土擁壁は、駐車場や工場等の敷地造成地の擁壁をはじめとして、山間地等に構築する補強土擁壁としても適用できる。 As described above, the earth retaining wall according to the present invention can be easily constructed by stacking a plurality of mochi net L-shaped units made of mochi net while embedding the embankment, so that it can be applied even in a place where the construction site is relatively narrow, such as an urban area. It is possible and suitable as a substitute for a concrete block retaining wall found in the city. Further, the earth retaining wall according to the present invention can be applied as a reinforced earth retaining wall to be built in mountainous areas as well as in a parking lot, a factory or the like.
