Filed: 1992-07-17
Abstract: PURPOSE:To facilitate the discharge of excavated earth to be discharged in a process which bores a drilling hole and the transportation of the soil based on a force feed process for the formation of improved soil in a mixing plant when forming a soil cement column in the ground. CONSTITUTION:When boring a drilling hole 23 on a ground 1 with an auger 4, water is sprayed to the ground so that a subsoil to be drilled is turned in a slurry state, which facilitates drilling work. This enables smooth transportation to a mixing plant 7 to be carried out by means of a force feed pump with less resistance. In addition, an improved cement material can be blended easily with the excavated subsoil slurry and agitated well. The resistance to the transportation from a swivel joint 12 of the auger to a pipe or the transportation by way of a hose is minimized so as to reduce a drive power. This construction makes it possible to homogenize the density specific weight of the improved earth (blended and kneaded earth) and form a high reliability soil cement column as designed.

Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a high-resolution peak voltage and peak slope detecting circuit for detecting the voltage of a battery during the charging sequence of the battery. SOLUTION: A battery charging circuit is disabled when the voltage of a battery is sampled so as to eliminate errors caused by noise. The voltage of the battery is sampled at prescribed time intervals during a prescribed period of time decided by a sample timer 46. A voltage/frequency converter 42 converts the voltage into a signal frequency. The number of pulses outputted from a VFC 42 is counted during the prescribed period of time. A counter comparator 44 counts the number of pulses, compares the counted value with the preceding sample, and locates a peak voltage. The peak voltage occurs when the sampled count is smaller than the preceding sample count. The changing rate of the voltage of the battery is monitored by a counter comparator 47 during a battery charging sequence to locate the peak slope.
