〈産業上の利用分野〉
本発明は、すでに完成している盛土の法面の勾配を、よ
り急勾配に修正する方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for correcting the slope of an already completed embankment to a steeper slope.
〈従来の技術〉
盛土とは土を盛り上げることによって広い平面部を新た
に造成し、その上に家屋、鉄道、道路などを設けて利用
するものである。<Conventional technology> Embankment is a method of creating a new wide flat area by heaping up soil, and then building houses, railways, roads, etc. on top of it.
こうした盛土の法面の勾配は、一般に土の安息角で形成
されているが、もしその勾配を急なものに修正すれば、
特に土地の価格が高騰している部会では大きな利益が得
られる。The slope of such an embankment is generally formed by the angle of repose of the soil, but if the slope is modified to be steeper,
Especially in subcommittees where land prices are soaring, large profits can be made.
そのために従来はＨ鋼などの杭を多数本垂直に打ち込み
、その杭の間に水平に矢板を挿入して土留を行う工法や
、あるいはタイロッドを地中に設置して法面の崩壊を防
止する工法などが採用されている。To this end, the conventional method was to drive many piles of H-steel or other materials vertically and insert sheet piles horizontally between the piles to retain the earth, or to install tie rods underground to prevent the slope from collapsing. construction methods are used.
く本発明が解決しようとする問題点〉
こうした従来の工法は、施工の規模が大きくなり、多大
の費用と工事時間を必要とする不経済なものであった。Problems to be Solved by the Present Invention These conventional construction methods are uneconomical, requiring a large scale of construction and a great deal of cost and construction time.
また大型の建設機械を必要とするため、地形によっては
機械が現場に接近できず、施工がきわめて困難な場合が
あった。Additionally, because large construction machines are required, depending on the terrain, the machines may not be able to access the site, making construction extremely difficult.
特に法面上の平面に家屋があったり、鉄道に利用されて
いる場合に、掘削によって法面が少しでも緩むと甚大な
被害を与えることになる。Especially if there are houses on the flat surface of the slope or it is used for railways, if the slope becomes even slightly loosened due to excavation, it can cause serious damage.
く本発明の目的〉
本発明はこのような点を解決するためになされたもので
、簡易な工事によって、その上の土地に影響をほとんど
与えることなく法面を急勾配に修正することのできる方
法を提供することを目的とする。OBJECT OF THE INVENTION The present invention has been made to solve the above problems, and it is possible to modify the slope to a steep slope by simple construction without affecting the land above it. The purpose is to provide a method.
〈本発明の構成〉
次に本発明の一実施例を、鉄道の盛土の勾配を修正する
場合について説明する。<Structure of the Present Invention> Next, an embodiment of the present invention will be described for a case where the slope of a railway embankment is corrected.
〈イ〉−段矢板打設（第１図）
法面１の最上部の肩から第一段の鋼矢板２を下向きに打
ち込む。<A> - Driving of tiered sheet piles (Fig. 1) Drive the first tier of steel sheet piles 2 downward from the shoulder at the top of the slope 1.
この打ち込み角度は、既設の法面の勾配よりも急な勾配
（実施例の図ではほぼ垂直）に設定する。This driving angle is set to a slope steeper than the slope of the existing slope (almost vertical in the figure of the embodiment).
この鋼矢板２の長さは、少なくとも２回分の法面の掘削
除去の高さに相当する寸法であって、盛土の土質、勾配
などによって決定する。The length of the steel sheet pile 2 corresponds to the height of at least two excavations and removals of the slope, and is determined depending on the soil quality and slope of the embankment.
く口〉第一段の掘削（第２図）
打ち込んだ鋼矢板２の面まで、外側の土砂を掘削し、除
去する。Excavation> First stage excavation (Figure 2) Excavate and remove the earth and sand on the outside up to the surface of the driven steel sheet pile 2.
この時に鋼矢板２の全長を掘削したのでは鋼矢板２が転
倒してしまう。If the entire length of the steel sheet pile 2 is excavated at this time, the steel sheet pile 2 will fall over.
さらに第二段の掘削を考慮して鋼矢板２の長さの半分以
下の寸法だけを掘削する。Furthermore, in consideration of the second stage of excavation, only a dimension less than half the length of the steel sheet pile 2 is excavated.
掘削面を長く露出してお（のは危険であるから、直ぐに
モルタルなどを吹き付けて表面の保護をはかる。It is dangerous to leave the excavated surface exposed for long periods of time, so protect the surface by spraying mortar immediately.
くハ〉ボルトの挿入、定着（第３図） 鋼矢板２の外部から、盛土の内部に向けて削孔を行う。Kuha〉Insertion and fixation of bolts (Fig. 3) Holes are drilled from the outside of the steel sheet pile 2 toward the inside of the embankment.
この削孔作業は掘削後の平らな面から行うことができる
。This drilling work can be done from the flat surface after drilling.
削孔が完了したら孔内にアンカボルト３を挿入する。When drilling is completed, the anchor bolt 3 is inserted into the hole.
そして、アンカボルト３の周囲にモルタルなどの硬化剤
４を注入する。Then, a hardening agent 4 such as mortar is injected around the anchor bolt 3.
その結果短時間の内にアンカボルト３が地山に定着され
る。As a result, the anchor bolt 3 is fixed to the ground within a short time.
く二〉アンカボルトの頭部処理
地山に定着したアンカボルト３の頭部だけが鋼矢板２か
ら露出している。2〉Anchor bolt head treatment Only the head of the anchor bolt 3, which has settled in the ground, is exposed from the steel sheet pile 2.
この露出部にベアリングプレート、横梁、などの支持部
材を取り付は鋼矢板２を拘束する。Support members such as bearing plates and cross beams are attached to this exposed portion to restrain the steel sheet pile 2.
以上の作業で第一段の高さＨｌの新掘削面の固定が完了
する。With the above operations, the fixing of the new excavation surface of the first stage height Hl is completed.
〈ホ〉第二段矢板打ち込み（第４図）
第一段の新法面の保護、固定が完了すれば、第二段Ｈ２
の鋼矢板２の打ち込みを行う。<E> Driving the second stage sheet pile (Fig. 4) Once the protection and fixing of the new slope of the first stage is completed, the second stage H2
Drive the steel sheet pile 2.
鋼矢板２打ち込み後のアンカボルトの挿入、定着、掘削
などは前記と同様である。After driving the steel sheet pile 2, inserting anchor bolts, anchoring, excavating, etc. are the same as described above.
〈本発明の効果〉
本発明は上記のような順序によって施工するから、次の
ような効果を達成することができる。<Effects of the present invention> Since the present invention is carried out in the order described above, the following effects can be achieved.
〈イ〉小規模の工事を積み重ねて行（方法であるから、
小型の機械のみによる施工が可能である。<B> Doing small-scale construction work one after another (because it is a method,
Construction can be carried out using only small machines.
したがって経済的であることはもちろん、足場や地形が
悪いところでも確実に工事を行うことができる。Therefore, it is not only economical, but also allows construction to be carried out reliably even in areas with poor footing or terrain.
〈口〉−度に大きな面積を掘削するのではな（、少しづ
つ鋼矢板で補強してはアンカボルトで拘束してゆ（工法
である。〈Excavate〉 - Don't excavate a large area at a time (this method involves reinforcing it little by little with steel sheet piles and restraining it with anchor bolts).
したがって、たとえその上部の平面を鉄道車両が走行中
の法面であっても、その運行に影響を与えることなく法
面の修正を完了することができる。Therefore, even if there is a slope on which a railway vehicle is running, the modification of the slope can be completed without affecting the operation of the slope.
