摘要： PROBLEM TO BE SOLVED: To secure grout filling performance in a duct by achieving a grout filling performance approximate to 100%, in vacuum grout-injection.
SOLUTION: In the process of injecting and filling a grout in the duct 8, the interior of the duct 8 is evacuated to attain a degree of vacuum reaching the upper limit degree of vacuum of the optimum range of vacuum, and then, a valve 15 installed at the end of the duct 8 is closed while constantly operating a vacuum pump 6. Further, when the pressure inside the duct 8 approaches a set lower limit value while the grout injection work is being continued, the valve 15 is opened to evacuate the interior of the duct to a target degree of vacuum. The operation described above is repeated to keep the interior of the duct 8 within a specified range of vacuum.

摘要： PROBLEM TO BE SOLVED: To realize a nearly 100% grouting rate in grouting in vacuum and guarantee the maximum-rate grouting performance in a duct.
SOLUTION: When grout is injected in a duct 8, the atmosphere within it is kept at a gauge pressure of -0.08 to -0.092 MPa. Before injecting grout, leak points on the duct 8 surface are confirmed by the sound of air flowing into the duct 8. An oil rotary or dry vacuum pump 6 provided with an oil and water separator 18 is used as a vacuum pump. This vacuum pump makes grouting possible on the highest possible vacuum level of not affecting the properties of grout. It can also largely reduce oil replacement frequency in the oil rotary vacuum pump 6, enhance its economic efficiency and improve grouting workability.

摘要： PROBLEM TO BE SOLVED: To provide a gap inspection device for a sheath pipe simply inspecting the gap in the sheath pipe not embedded in concrete.
SOLUTION: The gap detector attached to the sheath pipe is moved to the proper position on the pipe by the operation of a controller and incident waves such as ultrasonic waves or electromagnetic waves are emitted into the sheath pipe from the sensor of the gap detector. When its reflected waves are received by the sensor, the reflected waves are converted to a reflected wave signal to transmit the reflected wave signal to the controller and this controller judges the presence of a gap or the range of the gap using an analyzing processing part to display it on the screen of a display part.

摘要： PROBLEM TO BE SOLVED: To enable a viscosity measurement which complies with a fluidity test (JSCE-F531) specified by a society of civil engineers to be performed by easy operation without being influenced by skill and individual difference of a person who performs measurement.
SOLUTION: Mass of PC grout flowed down from a funnel 10 is measured by a scales 20. When a controller 30 acquires the measurement result as mass measurement data, the controller automatically calculates relation of the flow mass of the PC grout and time based on the mass measurement data. Then, after calculating mass-time which is measuring time in the case that an arbitrary range of flow mass of the PC grout is chosen as a measurement object, flow time is estimated by converting the mass-time with a flow time conversion formula corresponding to the flow mass.
