摘要： PURPOSE:To bore an underground hole having differing dia. through continuous excavating processes. CONSTITUTION:An underground boring machine is composed of a cutter device 2 to excavate the ground G, an excavator body 4 to excavate forward a hole 3 bored by the cutter device 2, and a guide plate 5 to adjust the excavating direction of the excavator body 4. An adjustable guide 6 is furnished on the outside of the guide plate 5, and an expanding/contracting mechanism 7 is furnished on the excavator body 4 to expand and contract the guide plate and adjustable guide 6 individually. With this mechanism 7, the adjustable guide can be located in a specified place on the excavator body, so that it is possible to accomplish an excavation hole having differing dia. through continuous operation using one excavating machine without requiring removing the front and rear guide plates, etc., or replacement of excavating machine.

摘要： PURPOSE:To reduce the cost and provide a sufficient supporting strength against a structure by a method wherein a notch part is formed in the lower part of a side where landslide protection for an underground continuous wall is carried out and the thickness of the upper part of the side is increased to a value higher than that of a lower part. CONSTITUTION:In an underground continuous wall 1, the thickness of an upper part 4 thereof is increased to a value higher than that of a lower part 5 thereof and a notch part 6 is formed in the lower part 5 and on the side where landslide protection is directly performed. The underground continuous wall 1 is built in a ground 7 and a side wall 8 is built at the inside of the underground continuous wall 1 through reinforcing bars 9. A bottom slab 10 is built at the lower part of the side wall 8 and at the underground continuous wall 1 through reinforcing bars 11 and a structure 12 is built at the upper part of the side wall 8. The notches 6 of the continuous underground wall 1 are formed on the side where the bottom slab 10 is built and on the opposite side on which landslide protection is applied directly and the lower end of a thin lower part 5 is arranged such that it is extended to a non-permeable layer or a support layer. This constitution causes reduction of the whole volume of the underground continuous wall 1 and ensurance of a sufficient support strength against the structure 12.

摘要： PURPOSE:To provide a method and device for properly controlling an automatic displacement correction of an excavator capable of automatically correcting displacement from a target of the excavator to control and excavation speed thereof without being influenced by ability, etc., of an operator. CONSTITUTION:The fuzzy theory is applied to displacement from a control target of the position of an excavator 5 and variation rate of the displacement during the excavation, expansion of a jack section 25 is controlled every specific short period and, at the same time, the fuzzy theory is applied to mean value of displacement and positive and negative code inversional frequency to control expansion and contraction of the jack section 25 every long period longer than the short period. According to the constitution, control performance varied from moment to moment is estimated from a control result by a displacement correction control section 37, gain is adjusted by a gain adjustment control section 38, and a control amount (an expansive control amount of the jack section) derived from the displacement correction control section is corrected.

摘要： PURPOSE:To promote reliability in attitude control of an excavator main body by accurately grasping coordinates of the excavator main body in the case of downward excavation by a controller and, at the same time, making receiving and transmitting of control signals between an excavator and a control section sure. CONSTITUTION:While receiving supply of data for an angle of inclination from upper inclined meters 16A and 16B and a main body inclined meter 24, excavation is made by an excavator main body 6 while revolving a rotary drum 17. In the case where the excavation is set in an automatic mode with a switch (b), excavation is made while controlling servo motors 26 and 28 as moving devices of slide tables 4A and 4B so that coordinates of C and D points calculated from data for an angle of inclination coincide with target value. By the control like this, excavation for a continuous wall, etc., can be made accurately while keeping the movement of the excavator main body 6 in a specific direction. Supply of angle data to a slide table control box 50 from the upper inclined meters 16A and 16B and main body inclined meter 24 or receiving and transmitting of signals for supply of control data to servo motor control sections 30A and 30B from the box 50 is made by a radio communication device 38.

摘要： PURPOSE:To excavate a tunnel of small width with a high degree of accuracy by providing a guide mechanism to an excavator in the case where the tunnel of small width connected to an excavated tunnel with large width is excavated. CONSTITUTION:The excavator 11 is formed out of an excavator main body 14 and a cutter devoce amd, at the same time, lower guide mechanism 16, intermediate guide mechanism provided in the excavated direction at an interval and upper guide mechanisms 18 are provided around the peripheral surface of the excavator main body 14. Guide plates 16b, 17b and 18c opposed to wall surfaces and expansion members 16a, 17c, 17d, 18c and 18d are provided to the guide mechanisms. After that, a tunnel with large width is continuously excavated by gravity due to dead weight of the excavator 11 as driving force in the excavating direction, and after a tunnel with small width is excavated in the ground, expansion members 18e and 18d of the upper guide mechanisms 18 are contracted, and the tunnel with small width is excavated further up to a specific depth by the cutter device 15 in accordance with the lower guide mechanisms 16.
