〔産業上の利用分野〕
本考案は軟弱地盤上への盛土をはじめ道路や堤
防等各種の盛土作業に使用し得るシートに関する
もので、シートの少なくとも両側縁を筒状に形成
し、必要によりこの筒状部に丸太等の嵩高物を挿

る。[Detailed description of the invention] [Field of industrial application] This invention relates to a sheet that can be used for various embankment works such as embankment on soft ground and roads and embankments. It is characterized in that a bulky object such as a log can be inserted into this cylindrical part if necessary.
従来ヘドロ等を含む軟弱地盤上への盛土に際し
ては、最初にヘドロを除去した後新しい土砂を投
入して盛土を行つていた。
Conventionally, when embanking on soft ground containing sludge, etc., the sludge was first removed and then new earth and sand was put in and the embankment was carried out.
また、軟弱地盤用ではないが、盛土の弛れ防止
手段としては、網により盛土の周縁を包被して積
層する方式の堤防構築方法がある。（特公昭48−
33102号）しかし、この方法は盛土側縁を包被す
る網の折り曲げ量を相当多くとらなければ盛土の
肩部が弛れる恐れがあり、また、この網は盛土の
側縁部のみを部分的に包むものであるため、軟弱
地盤の盛土には適用できないものである。 Although not suitable for soft ground, there is an embankment construction method in which the periphery of the embankment is covered with a net and layered as a means to prevent the embankment from loosening. (Tokuko Showa 48-
(No. 33102) However, with this method, there is a risk that the shoulders of the embankment may loosen unless the net that covers the side edges of the embankment is bent considerably, and this net only partially covers the side edges of the embankment. Because it is a method of enveloping soil, it cannot be applied to embankments on soft ground.
本考案は通常の道路や堤防などの盛土はもちろ
ん軟弱地盤にも適用でき、盛土側部が弛れない盛
土用のシートを提供するものである。
The present invention can be applied not only to ordinary embankments such as roads and embankments, but also to soft ground, and provides a sheet for embankments that does not loosen at the sides of the embankments.
本考案に係る盛土用シートの構成は、第１図に
示す如くシートの両側縁に筒状部を形成した
ものである。この筒状部は図面の如く、一定長
さのものを一定ピツチで設けてもよく、側縁全部
に設けてもよい。
The structure of the embankment sheet according to the present invention is as shown in FIG. 1, in which cylindrical portions are formed on both side edges of the sheet. As shown in the drawings, the cylindrical portions may have a certain length and be provided at a certain pitch, or they may be provided along the entire side edge.
この筒状部内には丸太等の棒状体を挿入す
るか、土砂等を適宜充填して盛土の際に使用され
る。従つて、側縁全部に筒状部が設けられる場合
には図示しないが、筒状部の軸線に対し直交する
方向の適宜個所に切り込みを設けて一定寸法の丸
太等がその切り込みから挿入できるようにすると
便利である。 This cylindrical part is used for embankment by inserting a rod-shaped body such as a log or filling it with earth and sand as appropriate. Therefore, if a cylindrical portion is provided on the entire side edge, notches (not shown) may be made at appropriate locations in a direction perpendicular to the axis of the cylindrical portion so that a log or the like of a certain size can be inserted through the notch. It is convenient to do so.
また、筒状部の形成に際してはシートの側縁
を折り曲げて縫いつけるか溶着等をして形成して
もよく、別体の筒状体を適宜手段にて取りつけて
もよい。 Further, when forming the cylindrical portion, the side edges of the sheet may be bent and sewn or welded, or a separate cylindrical portion may be attached by appropriate means.
本考案に係る盛土用シートは、第１図の如く軟
弱地盤を覆う如く敷設して両側縁の筒状部に
棒状体を挿入し、シート上部に第２図の如く盛
土を施した後シート両側縁の筒状部を持ち上げ
盛土上に折り返して基礎の盛土の側部を包被する
もので、この盛土工程を必要により数回繰返して
積層した後、最上部に盛土をして筒状部を盛土
内に埋設固定するものである。
The embankment sheet according to the present invention is laid down to cover soft ground as shown in Figure 1, rod-shaped bodies are inserted into the cylindrical parts on both side edges, embankment is applied to the top of the sheet as shown in Figure 2, and then the sheet is placed on both sides. The cylindrical part at the edge is lifted and folded back onto the embankment to cover the sides of the foundation embankment.This embankment process is repeated several times as necessary to stack the layers, and then embankment is placed on the top and the cylindrical part is covered. It is buried and fixed within the embankment.
本考案に用いるシートとしては、キヤンバス
のような不透水性のシートの他、透水性のものが
施行場所に応じて用いられ、また棒状物につい
ても丸太や土砂の他塩化ビニル製等の棒状体を用
いることができるもので、要は保形性とある程度
の嵩高を有するものであればよい。 As for the sheets used in this invention, in addition to impermeable sheets such as canvas, water permeable sheets are used depending on the implementation location, and rod-shaped materials include logs, earth and sand, and rod-shaped materials such as vinyl chloride sheets. In short, any material that has shape retention and a certain degree of bulk may be used.
また、最上部の盛土は必ずしも必要とするもの
ではなく、また、盛土に代えてアスフアルトやコ
ンクリートを敷きつめてもよい。さらに、筒状部
は両側縁に加えて全周縁に形成し、盛土を四方か
ら包み込むようにしてもよい。 Furthermore, the embankment at the top is not necessarily required, and asphalt or concrete may be laid in place of the embankment. Furthermore, the cylindrical portion may be formed not only on both side edges but also on the entire periphery so as to wrap around the embankment from all sides.
本考案は上述の如く、盛土に際しシートの側縁

となるので、折り返したシートに外向きの水平方
向の力が加わつた場合でも、筒状部の盛土へのく
い込みによる大きな抵抗力が働き盛土の側縁部
（肩）が容易に弛れることはない。
As mentioned above, the present invention involves inserting a rod-shaped body into the cylindrical part formed on the side edge of the sheet during embankment, lifting the cylindrical part on the side edge of the sheet after the embankment, folding it back, and enclosing the side part of the embankment. The cylindrical part sinks into the embankment surface due to the bulk of the rod-like material inside, and becomes embedded, so even if an outward horizontal force is applied to the folded sheet, the cylindrical part will not penetrate into the embankment. The side edges (shoulders) of the embankment do not loosen easily due to the large resistance force exerted by the embankment.
本考案の盛土用シートは道路や堤防の構築はも
とより軟弱地盤の上にでも安定した盛土が可能と
なるもので盛土施工上極めて有効な構造であり、
産業利用性の高いものである。 The embankment sheet of this invention is an extremely effective structure for embankment construction, as it enables stable embankment even on soft ground, as well as for road and embankment construction.
It has high industrial applicability.
