摘要： PURPOSE:To enhance improvement effect, also on the ground of high water- permeability including a gravel stratum, and heighten strength after improvement, specially, and enlarge an improvement diameter. CONSTITUTION:Through an injecting pipe 1 inserted into ground, from its tip section, the instantaneously bonding grout S of the solution type or the suspension type of a concreting time equal to or shorter than 60 seconds is injected and after that, from its injecting position or a tip side before the position, the reinforcing grout R of a suspension type with the concreting time longer than that of the instantaneous bonding grout S and with great homo/gel strength is injected. After that, from the injecting position of the reinforcing grout R or a tip side before the injecting position, the permeable grout L of a solution type with a concreting time longer than that of the instantaneous bonding grout S is injected.

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.

摘要： PURPOSE:To switch a number of switching valves by a simple operation by a method in which a follow gear is provided for the periphery of the main gear having teeth fixed to the lever shaft on its half-circumference alone and the switching valves are set in an interlocking manner with the gear. CONSTITUTION:The main gear 26 is provided with teeth only for its half circumference and fixed to the lever shaft 30, and follow gears 27, 28, and 29 are set in an engaging manner at intervals of 90 deg. on the periphery of the gear 26. A lever 34 is turned at 90 deg. each to turn any of the gears 27, 28, and 29 with its rotation. Any of switching valves 20-23 is switched as the lever 34 turns, permitting the switching valves to be switched according to a given process.

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.
