Title:
UNDERGROUND OPERATION DEVICE AND UNDERGROUND OPERATION METHOD USING THE SAME
Document Type and Number:
Japanese Patent JP2016035146
Kind Code:
A
Abstract:
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
