摘要： PURPOSE:To automatically estimate the geological feature of a pile hole with high precision by storing a number of boring data in correspondence with each depth and the excavation electric current, taking out the necessary data and comparing the data with the excavation electric current value for each pile hole. CONSTITUTION:A number of data which represent the geological feature 1 at each depth by the use of a motor-driven type boring machine and the boring electric current value 2 corresponding to the geological feature 1 is stored. Then, the electric current value 3 in the excavating a pile hole at a site is displayed in correspondence with the depth of the pit. Then, the data necessary for a computer 5 is taken out from a data base 4 in which a number of data are stored and displayed on a display device 6. The data of the data base 4 and the electric current value 3 corresponding to the depth in the pile hole excavation are compared, and the geological feature of the pile hole is estimated. Accordingly, the geological feature of the pile hole at each excavation position can be known automatically, and the geological feature in the direction of the depth of the pile hole can be estimated with high precision.

摘要： PURPOSE:To allow the exact detection of a position, direction, etc., by providing a transmission coil which transmits an AC electromagnetic field toward the front of detection, reception coils which receive induction magnetic fields and a reception circuit which detects a change rate of the peak value of reception voltages and phase difference. CONSTITUTION:The core 12A of the transmission coil 1A is extended toward the front of the coils 2A, 2A' and is orthogonally arranged in order to decrease the influence of the transmission magnetic field to be applied to the reception coils 2A, 2A'. Further, the coils 1A and 2A, 2A' are wound on bakelite bobbins contg. cloths and are so constituted as not to come into direct contact with the cores 12A, 12A'. The reception circuit 13A detects the change rate of the peak value of the AC voltage excited in the coils 2A, 2A' and the coil 1A and the phase difference between the waveforms of the transmission/reception voltages and the change rate of the peak value of the reception potential and the phase difference based on the moving distances of the coil 1A and the coils 2A, 2A'.

摘要： PURPOSE:To facilitate material management and injection management for grouting method by providing a mechanism for collecting solidification agent injection information on a solidification agent injection apparatus, and continuously and automatically creating the injection information in a daily report, a weekly report and monthly report. CONSTITUTION:A solidification material injection processing equipment 1 is roughly divided into a solidification material injection machine 2, a solidification material injection plant portion 3 and an information collecting portion 4. A solidification material is stirred by stirring blades 5 of the solidification material injection machine 2 while the solidification material is properly injected into an improved ground 30 by an auger 7, and when the improved ground 30 is stirred to a designated depth, the auger 7 is pulled up by a driving portion 6 to complete construction. According to a flow pulse signal of the information collecting portion 4, the flow per one pump, the total injection amount of plural pumps and the compounding weight of a solidification material are obtained in a daily report and weekly report by an information creating device 21 and a management device 20. Thus, material management and injection management can be facilitated.

摘要： PURPOSE:To increase cutting efficiency and extend the life of a blade of a core bit by selecting the dimension of core bit, setting the cutting target current of a first motor, comparing load current and the cutting target current value of the first motor and controlling the rotation of a second motor in a manner that the load current of the first motor is equivalent to the cutting target current value. CONSTITUTION:The dimension of a core bit is selected through a selector. Then, the cutting target current value of a first motor 11 corresponding to the dimension and the hardness of a material to be cut is set by a current setting instrument based on a selection signal from the selector. Then, the load current and electric cutting target current value of the first motor 11 sensed out by a current sensor are compared with by a control means, and the rotation of a second motor 16 of a feeding drive transmitting section is controlled by the control means in a manner that the load current is equivalent to the cutting target current value. Optimum cutting efficiency and the long life of a blade of the core bit can be secured even in case the dimension of the core bit and the hardness of the material to be cut are different by said arrangement.

摘要： PURPOSE: To reduce costs by connecting the pressure fluid passages of pressure cylinders to the pressure passages of pressure raising elements through the generation of pressure higher than that in a pressure fluid source. CONSTITUTION: When a hydraulic fluid is supplied via regulating valves 14, 114 to the respective pressure cylinders 8a, 8b, 108a, 108b of a retaining device 6 and a breaking device 7 which are adapted for rotating a rock drill rod about its axis, the fluid is guided by a thread breaking valve 16 to pressure raising cylinders 15, 115 via a passage 17. Pressures considerably higher than those normally produced in a hydraulic system are generated in passages 12, 112 by the pressure raising cylinders 15, 115. Even higher pressures are supplied to the pressure cylinders 8a, 8b, 108a, 108b and high clamping forces are imparted to clamping jaws 110a, 110b, etc.

摘要： PURPOSE:To form the shape of a bottom expanding section accurately according to a design by detecting the lowering depth and expanding width of a shell for expanding a bottom and controlling excavation while being compared with a previously programmed specified excavation pattern. CONSTITUTION:Both sidewalls of the shaft bottom section of a shaft 6 to be excavated are excavated and a bottom expanding section is formed, and concrete is placed, thus constituting a bottom expanding pile. In the method of construction, a shell 10 for expanding a bottom open-close driven by a hydraulic driving plate just above the shaft bottom section is elevated and lowered while biting in specified width to both sidewalls. The lowering depth detecting means 30 of the shell 10 and an oil gage as an expanding width detecting means are mounted at that time, and the depth and expanding width of the leading section of the shell 10 are computed automatically. A hydraulic control means and an elevation and lowering means are driven and controlled while the state is compared with a previously programmed fixed excavation pattern.
