It is characterized by having a lining spray nozzle which is provided opposite to the lowland as a target point.

[0008]

The pair of spray nozzles attached to the boss portion without the interposition of a beam block for lining a relatively small-diameter cylindrical body, etc., uses a lining material hose connected to the nozzle portion and a plurality of guide rods of a support frame. Can be guided from inside the support frame to both outer sides of the support frame through between the elements,
No hose bending force is applied to the connection between the hose and nozzle. Further, since the pair of spray nozzles on both sides of the boss portion are provided at different heights and lining sprays the same height wall surface, the lining material supply hoses of each spray nozzle do not interfere with each other in the support frame. .

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in FIGS. In FIG. 1, the turning drive unit 14
Is provided on the lower surface of the floor 2 of the gondola. The support frame 20 has a box-shaped elevating drive unit 21 having an upper end engaged with the swivel drive unit 14 and rotatably supported. 22 and four guide rods 23 fixedly connected to each other.
