摘要： PURPOSE:To improve the efficiency of the execution of work by providing the outer peripheral section of a rear section excavating-advancing machine main-body, with hollow elastic bodies, to lead fluid pressure and to expand it, and by swelling the elastic bodies, to apply excavating-advancing resistance to an excavating machine. CONSTITUTION:When an excavating-advancing locus is positionally shifted to be directed downward, from an estimated course at the time of excavating- advancing, then a lower side amendment jack 12 is extended, and a front section excavating-advancing machine main-body is oscillated to be directed upward. Then, compressed air is introduced from an air compressor via an air introducing port, into lower side elastic-bodies 111b-111d, among hollow elastic bodies 111a-111d arranged respectively in members 110a-110d projected in the four directions of the reaction plate of a rear section excavating-advancing machine main-body 11, and is expanded outside the outer peripheral surface of an excavating-advancing machine. As a result, the direction can be certainly amended.

摘要： PURPOSE:To correctly detect the position and attitude of a digging machine by means of a small-size measuring apparatus by operating and displaying the position and attitude of said digging machine on the basis of the detecting position of laser beams, turning angles in a horizontal direction and advancing distance of said digging machine. CONSTITUTION:A laser detecting apparatus 13 projects a detecting point on a target surface 14 of a laser beam 12 projected from a laser oscillator 11 to a CCD device 22, with operating and obtaining a positional displacement signal Xt and a positional displacement signal Yt in a horizontal and a vertical directions respectively and trans mitting to an I/O unit 25. The unit 25 changes an analog signal input from a turning angle measuring device etc. in a bent part, e.g., a pitching signal, a rolling signal, a turning angle signal, a speed signal of the digging machine or the liked into a digital signal, and inputs to an operating/processing device 26 along with the signals Xt and Yt transmitted from the device 13. Moreover,the unit 25 calculates the moving distance of the digging machine based on the speed signal and inputs the distance to the device 26. The device 26 operates the position and attitude of the digging machine on the basis of the input data from the unit 25, and displays the result to a display part 27.

摘要： PURPOSE: To perform safe and reliable excavation and lining by a method wherein an enlarging section is excessively excavated by the overcutter of a closed type rotary cutter shield machine and, after mud is grouted in the part, a segment is extruded. CONSTITUTION: In the middle of excavation of a tunnel by a closed type rotary cutter shield machine, a peripheral ground 14 of an enlargement scheduled section is excessively excavated in a shape matching with an enlargement shape by an overcutter mounted on a rotary cutter. Mud having plastic fluidity is grouted in an overbreak-excavated part from the shield machine and excavation is advanced as filling is carried out. Building of segments 12, 12, and 13 containing an ordinary part and an enlarging part is performed. Consecutively, after or during completion of excavation advance of an enlargement scheduled section, an existing segment 13 of the enlargement scheduled section is securely extruded in the overbreak excavated part, filled with mud, together with a short cylinder adapter 21 for enlargement.

CONSTITUTION:In a soil pressure feeder, a detector 8 to detect frictional force between soil 6 and the inner wall of a soil pressure feeding pipe 3 is provided in the vicinity of the soil trap tank 2 of the pipe 3. An amplifier 12 is also provided to the pipe 3, a meter 14 is provided near the operation section 11 of a charger, and the meter 14 and the amplifier 12 are connected with a cable 13. While the charger 11 is controlled, a tackifier is supplied through a charging tube 9 into the soil trap tank 2. Since the amount of the tackifier to charge can be regulated according to the degree of friction stress, soil can be fed under pressures with good efficiency.
