CONSTITUTION:A small bore pipe propulsion excavator is composed of a propulsion pipe 1, rotating mechanism R, a supporting frame 8, a box-type guide 10, an excavator 11, and the like. The rotating mechanism R and supporting frame 8 are fitted into a removable steel propulsion pipe 1. The box type guide 10 is oscillatingly fitted at the radial supporting frame 8, and the longitudinally movable excavator 11 is disposed in the box type guide 10. The cutting blade of the excavator 11 is opposedly moved by the rotation of the rotating mechanism R and the oscillation of the box-type guide 10 to excavate across the whole cross section of the cutting blade. The excavation of the ground or rock- bed of small cross section can be thereby performed easily.

摘要： PURPOSE:To absorb the vibration in the oblique direction, not only in one direction, by installing a damping member having an elliptical plane shape so that the direction of the longer axis coincides with the main wave motion direction of the liquid. CONSTITUTION:When a structure 1 is oscillate in the horizontal direction, e.g. A-B direction also a tank 3 oscillates in the A-B direction, and a liquid 7 oscillates in the A-B direction, and the vibration energy generated on the structure 1 is absorbed, and the wave motion of the liquid 7 is attenuated by a damping member 5, and a damping device 2 is applied with the effective damping performance. Further, if the structure 1 vibrates in the E-F direction in a horizontal plane, also the tank 3 vibrates in the E-F direction, and the liquid 7 starts vibration in the E-F direction in synchronization, and since the damping member 5 is formed into elliptical form on the planary form, the liquid 7 flows as shown by the bent arrow along the surface of the damping member 5. Therefore, the damping member 5 develops the damping performance also in the E-F direction which is oblique for the main wave motion direction, i.e., A-B direction, and the damper device 2 is applied with the effective damping performance.

摘要： PURPOSE:To effectively absorb the natural vibration in the higher order than the secondary order by installing a collected body in the integral assembly of several kinds of tanks in which the liquid having the wave motion frequency corresponding to the higher order natural frequency over the primary and secondary natural frequency of a structure of a structure is stored. CONSTITUTION:When a structure 1 is oscillated in the A-B (horizontal) direction, the liquid 9 in the first tank of a vibration suppressing device 5 starts oscillation in synchronization with the primary natural vibration of the structure 1. The liquid 11 in the second tank 10 starts oscillation in synchronization with the secondary natural vibration of the structure 1. Further, the liquid 15 in the third tank 13 starts oscillation, in synchronization with the third natural vibration of the structure 1. Then, the vibration energy of the structure 1 is absorbed by the wave motion energy supplied from the the liquid 9, 11. and 15. Further, the wave motion of each liquid 9, 11, 15 is attenuated by the damping member 7b, 10b, 13b in stalled in the tank 7, 10, 13, and the vibration in the A-B direction of the structure 1 is effectively absorbed by the tanks 7, 10, and 13 of the tank collected body 2.
