BORING DEVICE AND HOLE EXPANDING DEVICE
PROBLEM TO BE SOLVED: To provide a boring device which can bore a hole straight in a predetermined position while preventing the scattering of foam plastic waste when the foam plastic packed in a joint gap of a structure is removed.SOLUTION: A boring device 10 for boring a hole 6 in a foam plastic 5 packed in a joint gap 4 of a structure 1 comprises a shaft 11, a drill 12 fixed to one end of the shaft 11 and rotating integrally with the shaft 11, and a pipe 13 which is externally fitted over the shaft 11 and the drill 12 in a state that one end side of the shaft 11 and the part of the maximum diameter of the drill 12 are covered while the tip part 12e of the drill 12 is exposed and which is fixed to the shaft 11 and rotates integrally with the shaft 11.SELECTED DRAWING: Figure 3
【課題】構造物の遊間に充填されている発泡プラスチックを除去する際、所定の位置に真っすぐ穿孔でき、しかも、発泡プラスチックの屑が飛散し難い穿孔装置を提供する。【解決手段】構造物１の遊間４に充填されている発泡プラスチック５に孔６を穿つための穿孔装置１０であって、シャフト１１と、当該シャフト１１の一端に固定され前記シャフト１１と一体に回転するドリル１２と、前記シャフト１１の前記一端側と前記ドリル１２の最大径の部分とが覆われ且つ前記ドリル１２の先端部分１２ｅが露出した状態で前記シャフト１１および前記ドリル１２に跨って外嵌されると共に、前記シャフト１１に固定され前記シャフト１１と一体に回転するパイプ１３と、を備える。【選択図】図３
