本発明は、現場打設によるレジンモルタルトンネル壁の
築造工程中におけるレジンモルタルと硬化液を連続的に

ものである。Detailed Description of the Invention (Field of Industrial Application) The present invention provides a mixing casting machine that continuously mixes resin mortar and hardening liquid during the construction process of resin mortar tunnel walls by on-site casting. This is related to the screw.

動源によって駆動回転させられる。(Prior art) As shown in Fig. 4, the conventional mixing casting machine has a cylindrical outer box 1
The resin mortar and curing liquid, which are injected separately from the injection port 2.3 at the end of the holder, are mixed by rotating a screw 4 having a rotating shaft 5 and a spiral blade 6, while the resin mortar and curing liquid are poured into the discharge port side (right side of the figure). I am sending it to The rotating shaft 5 is driven and rotated by a rotational drive source not shown.

して吐出口側へ送られるという問題があった。(Problems to be Solved by the Invention) However, in the conventional device described above, since the rotating shaft 5 is a linear cylinder whose axis coincides with the center axis of the screw, the resin mortar around the rotating shaft 5 and the curing liquid were not mixed sufficiently. Therefore, there was a problem in that the resin mortar and the hardening liquid formed a layer and were sent to the discharge port side.
本発明は上記の点にかんがみ、回転軸自体にも撹拌機能

混合打設機のスクリューを提供するものである。In view of the above-mentioned points, the present invention provides a screw for a mixing and pouring machine in which the rotating shaft itself also has a stirring function so that the entire material is sufficiently mixed.

。(Structure of the Invention) Fig. 1 shows a mixing and pouring machine using a screw according to an embodiment of the present invention, 11 is a spiral blade, 12 is a rotating shaft with a spiral middle part, and 16 is a cylindrical blade. 14 is a resin mortar injection port, and 15 is a hardening liquid injection port. The rotating shaft 12 is connected to a rotational drive source (not shown) on the left side of the drawing.

者が十分に混合される。Since the spiral portion of the rotating shaft 12 itself rotates away from the center axis of the screw, this spiral portion is also stirred, and the resin mortar and hardening liquid form a layer and are sent to the discharge port. This prevents the two from being sufficiently mixed over the entire cross-section of the screw.

なされる。FIG. 2 shows another embodiment of a mixing casting machine using a screw, and in this example, the rotating shaft 12 is provided with a protrusion 16 that causes a flow in the direction opposite to the direction in which the resin mortar and hardening liquid are fed. This protrusion 16 agitates the resin mortar and hardening liquid around the rotating shaft, and provides sufficient agitation and mixing.

7 is provided at several places on the rotating shaft 1i. The small blades 17 can agitate the resin mortar and hardening liquid around the rotating shaft 1 and sufficiently stir and mix them.
