ATTACHMENT FOR FORMING CRUSHED STONE PILE, AND CRUSHED STONE PILE FORMING DEVICE COMPRISING THE SAME
To provide an attachment for forming a crushed stone pile suppressing occurrence of a failure in a connection structure of a base end side and a tip end side of a shaft.SOLUTION: An attachment for forming a crushed stone pile is attached to a crushed stone pile forming device forming a crushed stone pile in a space formed underground, is inserted into the underground to form the space, and forms the crushed stone pile in the space while ascending from the underground. The attachment comprises: a cylinder portion; a shaft which can be separated into at least two pieces that are a base end side shaft 50 and a tip end side shaft 42; a connection structure; and a cover 70. The shaft is disposed in the cylinder portion so as to rotate, and rotates by driving force from a driving device. The connection structure is disposed in the cylinder portion, and connects a tip end portion 52 of the base end side shaft 50 with a base end portion 44 of the tip end side shaft 42. The cover 70 is disposed in the cylinder portion and covers a periphery of the connection structure.SELECTED DRAWING: Figure 5
【課題】シャフトの基端側と先端側との接続構造に不具合が生じることを抑制する砕石杭形成用のアタッチメントを提供する。【解決手段】地中に形成した空間に砕石杭を形成する砕石杭形成装置に取付けられ、地中に挿入されて空間を形成し、地中から上昇しつつ空間に砕石杭を形成する砕石杭形成用のアタッチメントであって、円筒部と、基端側シャフト５０と先端側シャフト４２との少なくとも２つに分離可能なシャフトと、接続構造と、カバー７０を備えている。シャフトは、円筒部内に回転可能に配置されており、駆動装置からの駆動力により回転する。接続構造は、円筒部内に配置されており、基端側シャフト５０の先端部５２と先端側シャフト４２の基端部４４とを接続する。カバー７０は、円筒部内に配置されており、接続構造の周囲を覆う。【選択図】図５
