摘要： The purpose of the present invention is to provide an artificial ground freezing method having good coolant thermal efficiency without a gas-phase coolant being released into the ground or into the air. For that purpose, the present invention has: a freeze pipe (1: casing) for freezing the ground buried in the ground and a coolant circulation pipe (2) provided on the inside of the freeze pipe (1), wherein the coolant flowing inside the coolant circulation pipe (2) is carbon dioxide; and a coolant apparatus (10) that cools and supplies the carbon dioxide to the coolant circulation pipe (2), the coolant circulation pipe (2) comprising a first coolant circulation pipe (2A) on which a plurality of micro-coolant passages (2A delta) is formed, wherein the tip portion (tip portion in the ground) of the first coolant circulation pipe (2A) is connected to a plugging member (3: bottom socket) that connects the plurality of micro-coolant passages (2A delta) of the first coolant circulation pipe (2A) to a coolant supply side and coolant return side.

摘要： The purpose of the present invention is to provide a determining device and a determining method to determine whether an inspected jet nozzle is defective by inspecting the jet nozzle for injecting a jet stream with long ground penetrating distance at a stage before installing in a construction site where a large diameter jet grouting method is used. To achieve this purpose, with this invention, in which a nozzle to be inspected is mounted onto an outlet port, a jet stream is ejected from a jet stream generating device, and measurement data measured by a pressure sensing unit when the jet stream impacts the pressure sensing unit is processed with a controlling device (for example, a computer), a nozzle to be inspected is determined to be a non-defective product if a first ratio is no less than a first prescribed value, a second ratio is no less than a second prescribed value, and a third ratio is no less than a third prescribed value.

摘要： A contaminated soil remediation method activates a microorganism in soil contaminated with a toxic chemical substance. The contaminant is decomposed by a biodegradation reaction of the microorganism. The method involves forming a boring hole reaching into contaminated soil. A rod whose end is provided with a jet device is inserted into the boring hole. The contaminated soil is cut in a manner forming a flat-plate area in which the soil is intermittently cut by a microorganism activator, and the soil and the microorganism activator are mixed, by jetting water and/or the microorganism activator from the jet device.
