摘要： PROBLEM TO BE SOLVED: To excavate an excavation layer containing cobble stones, gravel, etc., and a rock-bed. SOLUTION: An excavation roller cutter 1 is constituted by rotatably attaching a sleeve main body 4 having a plate breaking tip 3 to the central part of a fixed shaft 2 via a bearing member 5. The breaking tip 3 is provided with a wedge-shaped bent edge 9 which is expanded from a sleeve main body by a projection quantity δ1 in the end face view of the sleeve main body 4. The wedge-shaped edge 9 may be provided with a wedge-shaped, inclined-faced, or bent-faced connecting edge and the breaking tip 3 may be combinedly used with a supplemental breaking tip, an auxiliary breaking tip, and an auxiliary side breaking tip. The presence of the wedge-shaped bent edge 9 of the breaking tip 3 can excavate the excavation layer containing cobble stones, gravel, etc., and the rock bed.

摘要： PURPOSE:To construct a vertical shaft in high reliability by way of efficiently excavating a bedrock by drilling by a hydraulic grab bucket until it reaches rock and by drilling and propelling by a rotary cutter device after it reaches the rock. CONSTITUTION:A circular casing 2 is oscillated and press fit into the ground, and its inside is drilled by a hydraulic grab bucket until it reaches a rock. After it reaches the rock, drilling and propulsion are carried out by a rotary cutter device 6 installed on the lower end of the casing 2. In this case, reaction force of thrust and rotating torque for digging of a base rock by the rotary cutter device 6 is taken from the casing 2 held by a vertical shaft drilling machine 1 to carry out press fitting and oscillation of the casing on the ground. It is desirable to repetitiously use water by jetting water from a rotating plate of the rotary cutter device 6, sucking up water and drilled pieces on the ground by a suction pump, separating water and the drilled pieces from each other in a water treatment tank 4 and circulating water in the casing 2.

摘要： PURPOSE: To drill even extremely hard rocks for large diameter piles, ventilating shafts or the like. CONSTITUTION: This drilling tool is releasably mounted to a lower end of a rod string 20 of a drilling rig and includes a container 2 having a cylindrical or truncated-cone shape fitted at the lower end with a plurality of cutting tools or cutters 10 for crushing rock. The drilling tool 1 further includes a plate 3 for releasably retaining a plurality of modular elements 14 forming a load 13, and curved blades 9, which are located in the proximity of the cutting tools, adapted for conveying rock spalls into the container 2 through suitable apertures in a bottom of the container 2. The cutting tools are mounted to a plurality of radial plates 7 securely fixed in the proximity of the bottom edge of the container 2. The curved blades are welded to the edges of the radial plates 7.

摘要： PURPOSE:To prevent looseness and deformation generated in a saddle body, to bear excavation reaction firmly, to exchange roller cutters easily and to reduce manufacturing cost. CONSTITUTION:A roller cutter 2, a shaft 3 and bearing sections 4a, 4b are assembled, a base plate 7 is fixed onto the bearing sections 4a, 4b by bolts 9, and the assembly is inserted into the roller-cutter mounting holes 10 of saddle bodies 5. The external wedge-shaped sections 6a of each arcuate key 6 are inserted into the external tapered grooves 11a of the saddle bodies 5, a pushing ring 8 is inserted into the roller-cutter mounting holes 10 of the saddle bodies 5, and the internal wedge-shaped sections 6b of each arcuate key 6 are brought into contact with the tapered surfaces of the pushing ring 8 and base plates 7. The base plates 7 and the pushing ring 8 are clamped by bolts 12, each arcuate key 6 is projected toward the outside in the radial direction from the tapered surfaces of the base plates 7 and the pusing ring 8, and fixed firmly in the external tapered grooves 11a of the saddle bodies 5.
