摘要： PURPOSE:To enhance the working efficiency by installing a sheet pile feeder which feeds and receives sheet piles between a concrete placing machine and a drawing machine and a rotary support apparatus which supports a guide of the drawing machine at an arbitrary angle to the ground. CONSTITUTION:A post 7 and a concrete placing and drawing machine 1 are erected at a right angle while a required amount of sheets piles 6 are mounted to a side chain feeder 4 and a bottom chain feeder 5 with a jig crane 12 and then a sheet pile handling device is arranged to run to a working site. Then, the chain feeders 4 and 5 are actuated so as to feed the sheet pile 6 to a specified position. A guide cell 2 is tilted until a striking and drawing unit 3 comes overhead the sheet pile 6 by driving a guide cell control jack and, moreover, the sheet pile 6 is clamped with an adaptor clamp 14 by lowering the unit 3. Furthermore, the guide cell 2 is moved to a sheet pile installation position and after it is erected, the sheet pile 6 is stricken and forcibly driven into the ground by means of the unit 3.

CONSTITUTION:Excavation bits 2 are provided to a plurality of end circumferential positions of an excavation pipe 1 having an inclination 3. After that, the fluid is supplied to the inside of a pipe in an excavation section, and the excavation pipe 1 is rotated while removing a slurry earth through the outside of the pipe to make a straight excavation. Then, the direction of excavation is examined in the excavation, and when the correction of the direction is required, the inclination 3 of the excavation pipe 1 is directed to a direction opposed to the direction to be corrected, and a drive excavation is made without rotating the excavation pipe 1. The direction of the excavation pipe 1 is corrected by the reaction force of a mud wall against the inclination 3. According to the constitution, rearrangement of tools is not required in the event of the correction of the direction, and a normal excavation is efficiently carried out and, at the same time, the direction can be corrected.

摘要： PURPOSE:To make easy the detection of directional correction by engaging a projection of inner pipe outer face to an inner face of outer pipe, feeding a pressure feeder with an angular detector into the inner pipe, and engaging the tip end of pressure fed body with the receiving part on the tipe end side of inner pipe. CONSTITUTION:An inclining face 9 at the tip end of an outer pipe 1 is positioned in a specified direction, and an outer protrusion 15 of an inner pipe 2 is met with the position of a projection 16 of the inner face of the outer tube in the longitudinal direction. The inner pipe 2 is rotated in a specified direction to engage the projection 15 with the projection 16 on the outside pipe 1 side. A pressure-fed body with an angular detector is slid into the inner pipe 2 so that the tip end of the body is engaged with a receiving part 13 on the tip end side of the inner pipe 2, thereby the circumferential angle is measured by the angle detector. After the pressure-fed is taken out of the inner pipe 2, the pipes 1, 2 are rotated for boring. A sure boring direction upon boring can therefore be detected.

摘要： PURPOSE:To enable an efficient bending correction by performing boring with a tip end bit while rotating an inner pipe and an outer pipe having an inclined face at its tip end in the tubular axial direction. CONSTITUTION:At a position where an abutting part of an inner pipe 2 is abutted against the inner face of a non-eccentric pipe hole part 10, outer and inner pipes 1, 2 are rotated to perform linear boring. The inner pipe 2 provided with a bit 4 and a fluid injection nozzle 8 at its foremost end is rotated while the outer pipe 1 of which inclining face at the fore end is inclined downward is made in non-rotation conditions, and the function of eccentric tubular hole part is also used, then the pipes 1, 2 are propelled for bending boring in the vertical direction. An efficient bending boring is therefore made possible.

摘要： PURPOSE:To obtain a value very close to an actual value by integrating an acceleration data per driving of a pile being divided into first and second halves to perform a synthesization with separate corrections of reference axes of a speed data thus obtained separately. CONSTITUTION:An impact acceleration during the driving of a pile is measured with an accelerometer and is corrected by multiplying the results by a specified window in the second half of the entire measuring time and a speed data is obtained by integration. At a first step, an initial value of the speed is set as zero value and at a second step, a mean of the speed data is determined for about one-third of the second half. With the results as zero value, the respective speed data are corrected entirely. Then, these speed data are synthesized between the first half of the former data and the second half of the latter data at such a position that the speed reaches the minimum value to determine a penetration rate.

摘要： PURPOSE:To obtain a displacement value which is very close to a real value by correcting all acceleration data with a mean value and integrating them to find a speed, correcting all speed data while regarding such an axis that the mean value of the speed data is zero within a range wherein displacement is originally constant as a reference line, and weighting and integrating the data. CONSTITUTION:Mean values of every 5-6 pieces of acceleration data are found and their mean value is used as a reference axis to correct and integrate all the acceleration data, thereby obtaining a chart (a) of the speed. Here, the actual displacement is as shown in a figure (b) and the speed should be zero within a range R. The reference axis S which is parallel to the inclination of speed data within the range R as shown in a figure (c) and sets the mean value of the speed data within the range R to a zero point is found and all the speed data is corrected based upon this reference axis. Further, the speed data within the range R are multiplied by a coefficient 1-e N for weighing and then integrated to obtain the waveform of displacement extremely close to a real waveform (b).
