【発明の詳細な説明】
この発明は地下連続壁を施工するに際して使用
され、拡底、拡巾しうる掘削機に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an excavator that is used when constructing an underground continuous wall and is capable of expanding the bottom and width of the excavator.
地下連続壁を地下構造物の支持くいに兼用する
場合、地下連続壁の先端部分の支持力不足と建物
荷重を連続壁に伝達させるシヤーキーの施工の困
難さが問題となる。そしてその問題点を解決する
方法として地下連続壁の底部または中間部を拡巾
することが要求され、そのため従来の掘削機を拡
巾施工もできるように改良することが試みられて
いる。 When an underground continuous wall is used as a support pile for an underground structure, there are problems such as insufficient support at the end of the underground continuous wall and difficulty in constructing a shear key to transfer the building load to the continuous wall. As a way to solve this problem, it is required to widen the bottom or middle part of the underground continuous wall, and attempts have been made to improve conventional excavators so that they can also perform widening work.
この発明も拡底、拡巾しうる掘削機であり、以
下その詳細を図示した実施例によつて説明する。 This invention is also an excavator that can expand the bottom and width, and the details thereof will be explained below with reference to illustrated embodiments.
掘削機の本体１には複数の主カツター２が略直
列状に配され、それに掘削土砂は吸引パイプ３よ
り排出されるようになつている。 A plurality of main cutters 2 are arranged substantially in series in a main body 1 of the excavator, and excavated earth and sand are discharged from the main cutters 2 through a suction pipe 3.

同位置まで回転円筒体５を降下させることができ
る。 The widening cutters 4 are arranged on both sides of the main cutter 2. A large number of bits are provided protruding around the rotating cylindrical body 5 supported by the horizontal axis. Further, this rotating cylindrical body 5 is driven by an electric motor 7 built therein. A horizontal shaft 8 supporting the rotating cylindrical body 5 is pivotally connected to the tip of a piston of a hydraulic cylinder 9 built in the main body 1.
By operating this hydraulic cylinder 9, the widening cutter 4 is pushed diagonally downward from the main cutter 1 to make it wider than the main cutter 1, and the rotating cylindrical body 5 is lowered to approximately the same position as the tip of the main cutter 2. can be done.

る。 When in use, with the widening cutter 4 stored in the main body 1, the main cutter 2 is used to cut the width W 1.
excavate a trench. To widen the width, the width widening cutter 4 is pushed diagonally downward from the main body 1 by operating the hydraulic cylinder 9 to widen the width W2 . After widening, the widening cutter 4 is stored in the main body 1 and pulled up.
なお前記ピストンを通じて横向き（矢印で示

ズル１０を設けることにより拡巾カツター４の掘
削能力を向上させることができる。 The digging ability of the wide cutter 4 can be improved by providing a high-pressure jet water discharge nozzle 10 that jets jet water laterally (indicated by an arrow) through the piston.
この発明は以上の構成からなり、拡巾カツター
は回転円筒体の周囲に多数のビツトが突設された
構成で一定巾の掘削が可能であり、機構も単純化
しうるので実用価値が大である。 This invention has the above-mentioned configuration, and the wide-width cutter has a configuration in which a large number of bits are protruded around the rotating cylindrical body, which enables excavation of a constant width, and the mechanism can be simplified, so it has great practical value. .
