摘要： PURPOSE:To enable attitude control by assuming displacement from instrumentation data for a direction of a shield excavator based on correlation between variations in the direction of the shield excavator and variations in displacement in the case position measurement data lacks. CONSTITUTION:Laser beams are irradiated to a target 16 provided to the inside of a shield excavator 11 from an automatic measurement device 15 installed in a fixed point in a tunnel. After that, the sight is adjusted to the target 16, and follow control of a sight direction is made to automatically perform always position measurement of the shield excavator 11. In the case position measurement data lacks, displacement is assumed from instrumentation data for a direction of the shield excavator 11 based on correlation between variations in the displacement and variations in deflection. Then, displacement estimated value is used as one of control parameter, and selection of jack patterns is made to make attitude control. According to the constitution, even if frequent view obstruction of the automatic measurement device 15 is made by workers or carrying articles, automatic attitude control is continuously implemented, and excavation can be carried out.

摘要： PURPOSE:To more early return to a planned line, and execute an accurate line correcting plan, without much waste when a segment assembling locus is largely deviated from the planned line on the way of a shield work. CONSTITUTION:When a deviated quantity of a shield machine 1 and an existing segment 2 from a planned line 3 is confirmed and correction of the line is required, a correction segment using plan for bringing the segment assembling locus close to a temporary target point C on the planned line is formed. A correction line from the planned segment assembling locus is decided based on the correction segment using plan. Next the excavation target line of the shield drilling machine required for assembling the segment on the correction line is decided.

摘要： PURPOSE:To prevent the occurrence of interference by a method in which an interference coordinate points of tail plate and segments are predicted and tail clearance is controlled. CONSTITUTION:After assembling one ring of segments, the coordinate of interference points B1i and B2i the tail plates are calculated on the basis of the acutal measuring position and direction of shield. On the basis of the calculated value and actually measured values delta1i the ordin of and delta2i of tail clearance, the coordinate of segment interference points A1i and A2i is calculated. On the basis of the calculated value and the next segment sizes, the coordinate of segment interference points A1i+1 and A2i+1 is calculated. Also, on the basis of the calculated value and predicted outlines (1) and (2) of shield after ring excavation, the coordinate of interference points B1i+1 and B2i+1 of tail plates on the position is calculated. Furthermore, on the basis of the interference points, tail clearance of the next ring is calculated to judge the suitability of control angle for excavation target. Necessary tail clearance can thus be secured by simple measurement.

SOLUTION: This device comprises units of a receiving device R for receiving the present position from GPS, a holding device S for holding the receiving device R, a GPS receiver 2, and an information processing device. The receiving device R is formed of a GPS antenna 7, a strut 10, and a balance weight 9 fixed to the lower part of the strut 10 so as to direct the strut 10 vertically. The strut 10 is nipped through a universal shaft coupling 8 with a fixed distance from the ground surface so that the lower part of the strut 10 does not make contact with the ground surface, and rotated around the horizontal axis. The receiving device R receives a signal showing a first present position from a GPS, and the GPS receiver 2 stores the signal. The information processing device displays the first present position and a target position. When the device is moved to a second position, the information processing device displays the moving path.

摘要： PROBLEM TO BE SOLVED: To provide a measuring device of an earthwork construction surface capable of easily seizing a quantity of required sediment at ground leveling work by precisely measuring construction accuracy of a ground leveling surface in real time. SOLUTION: This measuring device has GPS antennas 2a and 2b for detecting a position and a longitudinal directional inclination of heavy machinery 1, and a roller inclination sensor 4 for detecting a roller attitude of the heavy machinery 1, and has an on-vehicle control part 5 for inputting a signal from the GPS antennas 2a and 2b and the roller inclination sensor 4, a central control part 6 linked with the on-vehicle control part 5 by radio data, and display parts 7a and 7b connected to the central control part 6 or the on-vehicle control part 5. The on-vehicle control part 5 and the central control part 6 arithmetically operate the absolute height of the heavy machinery 1 by offsetting an inclination component of the heavy machinery 1 from the inputted signal. A difference between the absolute height of this actual ground leveling surface and the ground leveling surface height on a plan and a quantity of cut banking are displayed on the display parts 7a and 7b.

摘要： PROBLEM TO BE SOLVED: To enable the accurate detection of known points in a short time by GPS survey by providing a movable part comprising an antenna and laser oscillator on a horizontal transparent plate. SOLUTION: A detecting device 1 of known points whose coordinates are known by GPS survey comprises a transparent plate 11 placed horizontally, leg part 12 which supports the plate 11 horizontally, and a movable detecting part 13 with the antenna 61 of a mobile station and a laser oscillator 26. First, a reference point A located shorter in distance than the maximum length of the plate 11 from a known point P is detected by GPS survey as necessary, and the device 1 is placed so that the plate 11 may be located directly over the reference point A and known point P. The detecting part 13 is moved in a short distance on the plate 11 in any direction so that the coordinates of the antenna 61 indicated by GPS measurement may agree with the coordinates of the known point P to irradiate a plane of installation 23 vertically with a laser beam from the laser oscillator 26. By this, it is possible to detect the known point P by visual observation.

摘要： PROBLEM TO BE SOLVED: To provide a control system for immersing and setting to immerse and set a caisson accurately at a prescribed place by considerably reducing the time of surveying. SOLUTION: A data processing computer 16 operates an existing location and position of a caisson 2 on a basis of a position angle of the caisson 2 around an axis 3 that is detected by a gyrocompass 6, and three dimensional coordinates of the caisson 2 that is detected by an automatic tracking total station 8. Therefore, the caisson is immersed and set accurately if the caisson floating on the water moves to a horizontal or vertical direction, because a display 18 that is connected to the data processing computer 16 shows real time data of the existing location and position of the caisson 2.
