The edge guard strips 22 are arranged on two sides of the straight guide plate along the width direction, when the slurry slides down from the straight guide plate 21, the edge guard strips 22 block the slurry flowing to the two sides, so that the slurry is prevented from being scattered from the two sides, and the effect of guiding the slurry is also achieved. The straight guide plate 21 can be supported on the horizontal support beam 11, so that the material guiding member 2 is in an inclined state. When the slurry enters the inclined-state material guide piece 2, the slurry slides downwards to the grouting opening along the upper surface of the material guide piece 2 under the action of gravity, and the inclined state is more beneficial to the introduction of the slurry under the action of gravity. The lower extreme of guide 2 can support on the case roof beam, and support 1, guide 2 and case roof beam surface form triangle-shaped stable structure, make it be difficult for empting. The support 1 can also be supported on the ground, and if the height is insufficient, can also be supported on a horizontal support table built by the scaffold.

During construction, slurry is poured from a hopper to the feeding end 211 from top to bottom, and under the action of gravity, the slurry collides with the guide member 2, so that the guide member 2 collides with the horizontal support beam 11, and the pale noise can be generated, thereby influencing civilized construction, having soft rubber texture, isolating the guide member 2 from the horizontal support beam 11 and reducing noise.

In one possible embodiment, the elastic layer is formed with a relief texture on the surface.
