When the mine slope of 1 integral erection of shell, at ordinary times or when raining, at this moment the mine goes up the slope if have little rockfall or earth piece roll down the time, and because set square 18, the outside of curb plate 19 and roof 20 all presents the slope form, thereby can play the effect of a direction to little rockfall or earth piece, make little rockfall or earth piece can roll down along the outside inclined plane of set square 18, curb plate 19 and roof 20, avoid stopping in the top of shell 1, the effectual pressure that wholly applys to shell 1 that has reduced, it has good stability to have ensured that shell 1 has at the in-process of installation operation.

And when two down tube 15 promoted the movable block 16 and bolt body 17 carry out position control, fixed plate 25 will drive two fixed axles 27 this moment and promote and shelter from the whole emergence motion of shell 23 thereupon, and then can make and shelter from that shell 23 is whole can play good protection effect that shelters from to movable block 16 and bolt body 17 all the time, avoided causing external rainwater to erode bolt body 17 bottom male earth because of the position control of movable block 16 and bolt body 17, ensured the insertiveness in the middle of the earth of bolt body 17 is inserted, prevented that the whole emergence position of shell 1 from moving.
