Abstract: A piling machine includes a main body unit including a traveling device, a pile driver that performs piling, and a moving device that is connected to the main body unit and moves the pile driver. A control device performs piling while the traveling device is traveling (e.g., while the main body unit is moving). This reduces the number of times the traveling device stops, and thus, the number of times of acceleration and deceleration can also be reduced. In this way, energy efficiency can be improved.

The first detection device is configured to detect a variation in a physical quantity of the first portion.

Abstract: A scraper vehicle is described that can contribute, with a relatively simple and low-cost configuration, to shortening of a construction period, reduction of construction cost, and the like without travel being disabled easily. The scraper vehicle includes an auxiliary drive system that supplies, in excavation by the scraper, a driving force to at least part of traveling wheels of the scraper vehicle. The driving force is supplied constantly or in accordance with a travel resistance of the scraper vehicle.

Abstract: A hydrotalcite-like granular material having a grain size of 0.24 mm or larger is produced by drying a material that contains at least a hydrotalcite-like substance and that has a water content of 70% or lower at equal to or lower than a temperature at which the hydrotalcite-like substance is dehydrated of crystal water contained therein, preferably at 90° C. or higher and 110° C. or lower, such that the resulting hydrotalcite-like granular material has a water content of 10% or higher. In this manner, a hydrotalcite-like granular material that has a stable morphology and a high anion exchange performance and that can be produced at a low cost can be produced.

Abstract: A hydrotalcite-like substance capable of ion exchange with target anions, being of small crystal size that exhibits large basal spacing and excels at anion exchange performance; a process for producing the same; and a method of immobilizing hazardous substances. The hydrotalcite-like substance is produced by mixing an acidic solution containing aluminum and magnesium ions with an alkaline solution containing an alkali to synthesize a hydrotalcite-like substance, followed by, without ageing, water removal or neutralization. The molar ratio of aluminum ions and magnesium ions is preferably in the range of 1:5 to 1:2. Hazardous substances can be immobilized by pulverizing the hydrotalcite-like substance after synthesis and adding the powder to a subject, or adding a hydrotalcite-like substance in slurry form to a subject, or carrying out addition so as to cause the synthesis directly at the position of the subject.
