この考案は、溝掘りに使用されるショベル系掘削機のア
タッチメント、すなわち掘削パケットに関し、更に詳し
くは、バックホーに取り付けられる横掘り用掘削パケッ
トに関する。[Detailed Description of the Invention] This invention relates to an attachment for a shovel-type excavator used for trench digging, that is, a digging packet, and more specifically to a digging packet for horizontal digging that is attached to a backhoe.
一般に、ショベル系掘削機、特にバックホーによる下水
道等の溝（トレンチ）の掘削方法として第１図に示す縦
掘り方法、第２図に示す横掘り方法が行われている。2. Description of the Related Art In general, a vertical digging method shown in FIG. 1 and a horizontal digging method shown in FIG. 2 are used as methods for excavating trenches in sewers and the like using excavators, particularly backhoes.
すなわち、第１図の縦掘り方法は、バークホーＡを掘削
されるべき溝Ｂをまたいで順次掘削バケツｔ−Ｃにより
矢印方向に掘削を進めてゆくものである。That is, in the vertical excavation method shown in FIG. 1, excavation is sequentially carried out in the direction of the arrow by the excavation bucket t-C over the trench B to be excavated using the bark hoe A.
これによれば、掘削作業が迅速に行われる利点を有する
反面、溝の両肩の地盤がバックホーの走行輪によって踏
み荒されること、掘削溝の直近に電柱あるいは建造物等
の障害物があるときには掘削作業が不可能ないし困難に
なること等の欠点がある。Although this has the advantage that excavation work can be carried out quickly, it also means that the ground on both shoulders of the trench is trampled by the running wheels of the backhoe, and that if there are obstacles such as utility poles or buildings in the immediate vicinity of the excavated trench, There are disadvantages such as making excavation work impossible or difficult.
また、第２図の横掘り方法は、バックホーＡを掘削され
るべき溝Ｂの一方の側に設置し、バックホーＡの進行に
合わせて順次掘削パケットＣにより土砂を横取りにして
矢印方向に掘削を進めてゆくものである。In addition, in the horizontal digging method shown in Fig. 2, backhoe A is installed on one side of trench B to be excavated, and excavation is carried out in the direction of the arrow by sequentially intercepting earth and sand with excavation packet C as backhoe A advances. We will continue to move forward.
これによれば、溝Ｂの両肩の地盤を妄りに踏み荒すこと
なく、かつ、掘削溝の直近に存在する障害物が可及的に
回避して作業ができる利点を有する反面、掘削溝の両側
の法面の掘削が不揃いで有効な深さの溝を掘削すること
が困難なこと、法面の土砂が崩れて路肩が不安定となる
こと等の重大な欠点を有する。According to this, there is an advantage that work can be carried out without trampling the ground on both shoulders of trench B, and while avoiding obstacles that exist in the immediate vicinity of the excavated trench as much as possible. It has serious drawbacks, such as the uneven excavation of the slopes on both sides, making it difficult to excavate a trench of effective depth, and the soil on the slopes collapsing, making the road shoulder unstable.
本考案は上記実情に鑑み、上記横掘り方法における欠点
を解消した新規な横掘工法用掘削パケットを提供するこ
