【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、曲管を地上から地中に順次推進敷設する、
所謂円弧推進工法において、口元管や推進すべき曲管を
地中に圧入するための圧入装置及びその使用方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention lays curved pipes in order from the ground to the ground.
In a so-called arc propulsion method, the present invention relates to a press-fitting device for press-fitting a mouth pipe or a curved pipe to be propelled into the ground and a method of using the same.
比較的短幅の道路下、水路下等に曲管を弧状に推進敷
設するための工法として、所謂円弧推進工法が知られて
いる。この工法は、敷設すべき曲管（鞘管）の先端から
突出した掘削ドリルで地中を曲管外径よりも大きい径で
掘削し、曲管ユニットを地上側で順次接続しながら地中
に推進させることにより、曲管を円弧状に敷設するもの
である。A so-called arc propulsion method is known as a construction method for propulsively laying a curved pipe in an arc shape under a relatively short road, under a waterway, or the like. This method uses an excavation drill that protrudes from the tip of a curved pipe (sheath pipe) to be laid to excavate the underground with a diameter larger than the outside diameter of the curved pipe, and connect the curved pipe units to the ground side one after another. The curved pipe is laid in an arc shape by being propelled.
このような工法では排土の排出を円滑に行わしめるた
め、地上から数ｍ程度の深さまで推進曲管よりも大径の
口元管を埋設し、曲管をこの口元管を通じて地中に推進
