摘要： PURPOSE:To enhance the efficiency of the execution of work, and ensure the effect of improvement. CONSTITUTION:An injecting pipe 1 having the two injecting pipes of a base end side injecting port 2A and a tip side injecting port 2C at least in the length direction, is inserted into ground. As a first process, from the base end side injecting port 2A, the instantaneous bonding grout S of a concreting time equal to or shorter than 60 seconds is injected, and after that, as a second process, the injecting pipe 1 is stepped up, and from the injecting port 2A on the base end side, the instantaneous bonding grout S is injected. Besides, without moving the injecting pipe 1, from the tip side injecting port 2C faced to the same position as that of the injecting zone of the instantaneous bonding grout S injected in the first process, or a front side position, loosely bonding grout L with a concreting time longer than that of the instantaneous bonding grout S is injected. Then, these processes are repeated, and the injecting pipe is stepped up and after that, a time point when the loosely bonding grout L is injected is set after a time point when the instantaneous bonding grout S before stepped up is injected.

摘要： PURPOSE:To prevent generation of trouble by simplified operation by constituting a device switching a work process to the predetermined work process only by displacing a valve unit means by the predetermined quantity when feed work of chemicals is performed by a double pipe feeder rod. CONSTITUTION:The first, second and third communication passages 32, 33, 34 are provided in a movable manifold 122 with the first communication passage 32 having inlets 35, 36 communicatable with the first and second inflow holes 23, 24, second communication passage 33 having an inlet 38 communicatable with a pump outflow hole 30 and the third communication passage 34 enabling communication to be performed between the third and fourth outflow holes 27, 28. The movable manifold 122 corresponds respectively to a feed process of flash setting material, switching process between flash setting agents, depressurizing process and a feed process of retarder setting material, and a position is obtained to each process by rotating the movable manifold 122 with an angular interval of 90 deg.. Accordingly, a valve device, enabling generation of trouble to be prevented with simplified operation, can be obtained in a chemical feeder.

摘要： PURPOSE:To simplify constitution and facilitate operation and permit the constant quantity supply and prevention for counterflow by connecting a casing equipped with a constant quantity transporting member onto the underside of a hopper and connecting a transport pipe having a pressurized air injection nozzle and a diffuser onto the outlet of the casing. CONSTITUTION:The particulate material in a hopper 1 is supplied by a constant quantity into a transport pipe 9 through a casing by the revolution of a screw 6. The supply quantity at this time is determined by the number of revolution of the screw 6. When the pressurized air is jetted toward a diffuser part 10 from a nozzle pipe 11, a negative pressure is generated by the throttle effect in the case when the jet stream passes through the diffuser part 10, and a jet ejector action is generated, Therefore, the powdered granules are certainly fed forwardly by the jet ejector action and the pushing-out action of the screw 6. With such constitution, the particulate material can be certainly supplied by a certain quantity free from counterflow.

摘要： PURPOSE:To curtail the cost of an excavator by a method in which a rotary shaft is thrust and projected from a supporting frame, a second supporting arm is pivotally attached to both ends of a first supporting arm pivotally attached to the rotary shaft, and a bit to be driven by the rotary shaft is attached to the outer end of the arm. CONSTITUTION:A center bit 14 is attached to the lower end of a drill pipe 3 set in a well 2, and a first supporting arm 5 is pivotally attached to the upper part of the pipe 3. A second supporting arms 8 and 9 are pivotally attached to both ends of the arm 5 in a bendable manner, and outer ring bits 12 and 13 are attached to the end of the arm 5. At he beginning of excavation, the arms 5, 8, and 9 are bent and the bits 12 and 13 are contacted with the inner wall of the well 2 to excavate the inside ground of the well 2 in conjunction with the center bit 4. When the bits 12 and 13 reach the cutting edge of the well 2, the second arms 8 and 9 are opened, the excavating radius of the bits 12 and 13 is increased, thereby excavating the ground below the cutting edge of the well 2.

摘要： PURPOSE:To enhance operating efficiency. CONSTITUTION:A casing 2 is constructed into a given ground position using a rotary percussion drill 1 and a filling tube 3 is inserted into the casing 2, and while flowout preventive means 4 for preventing grout from flowing above the ground are working between the casing 2 and the wall of the hole and between the casing 2 and the filling tube 3, grouting is carried out by way of the filling tube 3. After the grouting is completed, the casing 2 and the filling tube 3 are pulled by predetermined lengths and at this pulled stage grouting is carried out, and these pulling and grouting operations are repeated.
