摘要： PURPOSE:To enable sure simple execution by providing on the front end of a machine body an impeller connected to a mixture supply means and on the peripheral side of the impeller a rotary shaft to change the direction of projection with a pivotal operation mechanism or project the mixture parallel to the execution plane. CONSTITUTION:A collapsible arm 52 is mounted to a machine body 50 having a travelling means 51. and provided on the front end with a slide lever 53 and a projecting mechanism 10. Then, the projecting mechanism 10 is provided with a rotary impeller l and mixture supply means 2 and a connecting member 3 for these means is provided with a rotary shaft 4 connected to a motor 33. Next, the supply means 2 is provided with a ribbon screw 21 rotated by a motor 22 to send the mixture sent from a supply port 26 to the peripheral side of the impeller l and mix it by a change-over piece 24. A quick-setting agent or the like is replenished from an introducing port 27 to form an introducing section 25 having rubber-like elasticity. Thus, the rate of rebound and a produced powder dust amount are reduced so that the mixture projection excellent in strength can be performed.

摘要： PURPOSE:To improve construction efficiency when a mixture such as cement is fed to a high rotational speed impeller and projected to a surface to be constructed by specifying the rotational speed of the impeller or other conditions. CONSTITUTION:When a mixture, which is fed from a feed port 26 by rotating a ribbon screw 21, is fed to the outside of an impeller 1 and projected to a surface to be constructed, the circumferential speed of the impeller is 18-35m/sec. Next, when a mixture composed of hydraulic powder such as cement etc., water and aggregate, and liquid or set accelerating agent in the form of powder is supplied, the agent is scattered over the entire sectional region of a feed passage of the mixture with respect to the impeller. And when the agent is powder, the agent is added under air pressure of 1 kg/cm or lower. And an agent feed port 27 is located at a point spaced a distance corresponding to about one revolution of the screw 21 from the rear side of a feed port 26. Further, a space having a diameter equal to 40% or less of the diameter of the screw 21 is formed axially in the middle of the screw 21. As a result, a rebound ratio and the amount of dusts can be largely reduced and strength can be improved.

摘要： PROBLEM TO BE SOLVED: To effectively execute a shield work in the economical face, the management face, and the construction period face, by providing sealing means at the outer periphery of a shield machine and sealing the gap between the tunnel wall and the shield machine in passing through the tunnel wall of an arrival shaft. SOLUTION: Pressing type sealing means 4, 5 continuing in the circumferential direction are provided in two stages with a distance from each other in the excavating direction in advance, in the skin plate 3 of the outer periphery of a shield machine 2. When the sealing means 4 of the front end has positioned within the thickness range of the tunnel wall 1 of the arrival shaft, the first stage 4 of the sealing means is actuated with pressure. And then, the second stage 5 of the sealing means is actuated with pressure before the first stage 4 of the sealing means 4 passes through the tunnel wall 1 of the arrival shaft. In this way, one of the sealing means 4, 5 seals always the gap 1a from the tunnel wall 1 when the shield machine 2 pierces the tunnel wall of the arrival shaft. Accordingly, the shield work can be effectively executed in the economical face, the management face, and the construction period face.
