Novel let and press supporting strutting device

The utility model discloses a novel let and press supporting strutting device, it includes stock, stock nut and track steel sheet, the track steel sheet passes through the lower surface at the roof is fixed to stock and stock nut, and it presses the anchor dish still to be equipped with between track steel sheet and the stock nut to let, it lets the compressive strain cushion steel pipe and anchor dish to let pressure anchor dish include, let compressive strain buffering steel pipe fix one side of anchor dish. The utility model discloses a strutting former steel band to replace into the track steel sheet and let and pressing the cooperation of anchor dish to strut, make the supporting intensity in tunnel and security obtain the improvement, roadway deformation reduces by a wide margin, and the phenomenon of repairing after digging before having stopped has improved the manufacture order tie of intaking. Simultaneously, through letting the flexibility of pressing the anchor dish strut, after roadway support ac
