UNDERGROUND OPERATION DEVICE AND UNDERGROUND OPERATION METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide an underground operation device of a relatively simple structure, capable of, for example, investigating immediately under a structure and establishing a solidified body for ground improvement based on the investigation result or a construction design.SOLUTION: An underground operation device includes: a guide member 2 penetrating into and installed in a ground from a ground surface side or pulled out, roughly vertically; feeding means 3 supported by the guide member, having an extension member extended roughly horizontally in the ground from around a tip side of the guide member; and operation means comprising excavation means 26 installed on a tip side of the extension member and transferred along the guide member 2 from the ground surface side through a feeding passage, an injection nozzle injecting a ground improvement fluid, and/or investigation equipment such as a camera for observing and a sensor for sensing underground conditions.SELECTED DRAWING: Figure 1
【課題】比較的簡易な構成により例えば構造物直下の調査、その調査結果又は施工設計に基づいて地盤改良用固化体を造成できる地中作業装置を提供する。【解決手段】地中作業装置として、地表側より地盤内に略縦方向に貫入配置したり引き抜かれるガイド部材２と、前記ガイド部材に支持された状態に設けられてガイド部材の先端側周辺から地中の略水平方向に伸縮される伸縮部材を有した繰出し手段３と、前記伸縮部材の先端側に設けられて、前記ガイド部材２に沿って地表側より供給経路を介して移送される掘削手段２６や地盤改良用流体を吐出する噴射ノズル、又は／及び、地中の状況をカメラ等で観察したりセンサ等で感知する調査機器からなる作業手段とを備えている。【選択図】図１
