摘要： PURPOSE:To secure concrete strength and fast self-supporting characteristics of an edge face by mixing a specified quick setting agent and a setting retarder to concrete, supplying accelerator after having transmitted to concrete placing places, and filling excavation grooves that run along facing periphery. CONSTITUTION:An excavation groove 20a is excavated to correspond to a span of specified depth and width with a cutter 4, and concrete 6 is consecutively placed into the following, existing excavation groove 20b from a press feeding pipe 5. Further the concrete placing is repeated in order along the periphery of the facing 2, and an arch lining body 20 is integrally constructed. After a specified time has elapsed since uniform mixing of a quick setting agent and a setting retarder to the concrete 6 and the concrete 6 has gained a specified strength, an edge face is treated with the action of an accelerator. Alumino- calcium silicate glass and calcium sulfate are used as the accelerator and mixed with a setting refer, and the mixture is transmitted to the place of concrete placing by a concrete press feeding pipe 8b. And before coming to the facing, the accelerator is supplied to the press feeding pipe 8b, and filled into the excavation groove 20b along the facing periphery for timbering of the peripheral face of a tunnel.

摘要： PURPOSE:To generate uniform mixing by furnishing a U-pipe rotating in crank form on the way of a concrete pressure feed pipe, and shearing the concrete to which an early-strength additive is added, in the form of thread cutting at the rotational boundary of the base of U-pipe. CONSTITUTION:A concrete rapid solidifying agent, etc., is injected from an early-strength additive supplying nozzle 6 into the fixed straight pipe portion 2b of a pressure feed pipe 2 and mixed with the concrete which is pressure fed within the pipe. The concrete is pressure fed along the axis (a) of the pipe 2b, and at intruding into a U-pipe 10, is fed in eccentricity from the axis (a). Then the U-pipe 10 is rotated by a motor 20 through a gear 19 while the axis (a) is rotated round the center shaft (b), so that the concrete is sheared at the rotational boundary 21 between the fixed straight pipe portions 2b, 2c and the U-pipe 10. The concrete is spirally inverted and sheared continuously so that mixing of the rapid solidifying agent is promoted. This accomplishes uniform mixing of early-strength additive in the concrete pressure feeding process.

摘要： PROBLEM TO BE SOLVED: To provide an operation control device for a dust collector which can efficiently and economically operate the dust collector that is for use in civil engineering work including specific work steps in which dust generation is expected. SOLUTION: At the execution of a tunnel excavation work, when the specific work steps in which dust generation is expected including "a blasting step", "a muck removing step", "a spotting step", and "a spraying step" are started, a blasting step detecting sensor 3, a muck removing step detecting sensor 4, a spotting step detecting sensor 5, and a spraying step detecting sensor 6 output respective detecting signals corresponding to the steps, and the control device 2 controls the dust collector 1 according to the detected signal. In the steps other than the steps in which dust generation is expected, the specific work step detecting sensors halt the outputting of the detecting signals, and therefore the control device 2 sets the dust collector 1 in a quiescent mode or a slow-operating mode.
