摘要： PROBLEM TO BE SOLVED: To provide an excavator capable of excavating a large hole deeply by a main excavator after a small hole is excavated by a preceding excavator and also recovered by pulling it up without being interfered with protective materials for the large hole. SOLUTION: A casing 11 is connected to an auger pipe 6 raised and lowered by a base machine lifter, and an excavating part 12 is provided at the tip part of the casing 11 to form a preceding excavator 10. A main excavator 40 is installed on a slide frame 20 slid along the casing 11, and the casing 11 is lowered deeply into the ground together with the auger pipe 6 so that a large hole can be excavated deeply into the ground by the main excavator 40. The main excavator 40 is installed on an inner peripheral cutter head 41 so that an outer peripheral cutter head 42 can be separated from the inner peripheral cutter head 41, a cutter 43 is installed on each of these cutter heads, and the outer peripheral cutter head 42 is separated from the inner peripheral cutter head. Thus the excavator can be pulled up for recovery without being interfered with protective materials for the large hole.

摘要： PROBLEM TO BE SOLVED: To provide a conveyance technique capable of efficiently conveying a wide variety of conveyance objects, without being affected by viscosity. SOLUTION: A screw auger 4 is pivotally housed inside an auger casing 1, having an intake 2 and an exhaust 3 formed on both ends. A negative pressure generating source 10 is connected to the exhaust part 3 which communicates with a helical space inside the casing 1. Both force of an extrusion force due to frictional force between vanes 6 of the screw auger 4 and a negative pressure suction causes force to act over the entire length of the helical space inside the auger casing 1 acts on a object to be conveyed and conveys it.

摘要： PROBLEM TO BE SOLVED: To easily indicate a reaction force by providing a convertion means receiving a reaction signal from a device to the controlled and converting it to a stimulation signal, and stimulation electrodes connected to the convertion means and attached to an operator's body to impart the stimulation signal. SOLUTION: When an operator controls an operating device 3 while watching the movements of a device 1 to be controlled such as a back hoe on an indicator such as a CRT 23 or the like, an operation signal 11 is transmitted to a controller 21 on a control means of a control device 2. The operation signal 11 is converted to an operation signal operating the device 1 to be controlled by the control device 2. When the device 1 is operated, a reaction signal 12 is transmitted to a convertion means 22 of the control device 2 to convert it to a stimulation signal 13. Further, the stimulation signal 13 is imparted to an operator through stimulation electrodes 4 attached to the operator's body such as his arm or the like to impart the reaction force. In this way, the reaction force can easily be indicated.

CONSTITUTION: An excavator is equipped with a casing 11 with a non-circular section, a rotary shaft 12, a hammer 13 giving striking force to an excavation bit 131, and cylinders 14a and 14b bored between the casing 11 and a middle part of the hammer 13 and vibrating the hammer 13. Then, casing 11 is placed on a bedrock 90 to be excavated, striking force is given to the excavation bit 131 by supplying compressed air intermittently through air supply holes 121 and 134 and, at the same time, the rotary shaft 12 is rotated to provide torque to the excavation bit 131. Then, the bedrock 990 is excavated with the excavation bit 131 by striking force and torque, at the same time, the cylinders 14a and 14b are alternately expanded, and when the hammer 13 is vibrated with the basic end 132 as the center, the excavation bit 131 is horizontally reciprocated, and the lower part of the casing 11 is ovally excavated.

摘要： PURPOSE:To prevent clogging and improve efficiency by providing a fixed bit protrusively at the tip inner part of a nozzle for sucking excavated earth, and slidably mounting an outer cylinder provided with a tip bit so as to suck the excavated earth after crushing it. CONSTITUTION:When a suction pump 8 outside of a pit is actuated, the cylinder 4 of a suction nozzle 1 starts expanding/contracting action, and in this state, the tip of the nozzle 1 is brought close to excavated earth 9. Then the excavated earth 9 is discharged through an earth discharge hose 9 by vacuum suction. In this case, earth clods are crushed fine by the peripheral bit 31 and tip bit 32 of a sliding outer cylinder 3, and earth clods larger than the inner diameter of a nozzle body 2 are crushed fine by a fixed bit 21 protrusively provided at the inner surface of the nozzle body 2, and the vertically moving tip bit 32. Clogging in the nozzle and the hose is thereby prevented, and the efficiency of excavated earth conveyance can be improved.

摘要： PROBLEM TO BE SOLVED: To heighten accuracy in the measurement of point loading strength and to simplify measurement. SOLUTION: In this loading test device or measuring method, a specimen 2 is sandwiched between a pair of pointer 34 and 35 to measure the diameter of the specimen 2. The pointers 34 and 35 are moved so as to provide a uniform loading speed for the specimen 2 to measure a point loading load at the time when the specimen 2 is broken. Point loading strength is computed from the diameter of the specimen 2 and the point load. As it is possible to perform test easily in a short time at the site of specimen collection during the execution of construction work and to immediately reflect test results without delay in the work, it is possible to improve work efficiency. In addition, by automatically measuring the diameter of a specimen and a breaking load, it is possible to improve measurement accuracy. By maintaining a constant loading speed and reducing variations in loading strength to be obtained, it is possible to obtain highly reliable test results.

摘要： PURPOSE:To improve functionality by a method wherein an excavating device is mounted on the one side of a revolving body having a running function and a loading device is arranged to the other side of the revolving body. CONSTITUTION:A loading device 3 performs both two excavating and loading works and provided with a vertically and longitudinally rotatable boom 31 and a bucket 32 located in an oscillating state to the end of the boom 31. An excavating device 4 aims to excavate a rigid ground, e.g. bedrock, a part thereof is pivotally supported to a slewing body 2, and the excavating part of the excavating device 4 is elevated through expansion and contraction operation of a cylinder 41. When an ordinary ground is excavated, a bucket 32 of the loading device 3 is used, and when excavation is carried out down to a rigid ground, excavation is effected by using the excavating device 4. This constitution excavates all kids of soil through a single excavating device and improves functionality.
