Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, an underground tunnel construction uses auxiliary stay device, including base 1 and pneumatic cylinder 2, the equal fixed mounting in both ends has pneumatic cylinder 2 about base 1 top, the top of pneumatic cylinder 2 all imbeds and is provided with piston rod 201, the top fixed mounting of two piston rod 201 has crossbeam 3, the top fixed mounting of crossbeam 3 has backup pad 4, the middle part bottom fixed mounting of backup pad 4 has main strengthening rib 5, the equal fixed mounting in both ends has flank strengthening rib 6 about backup pad 4 bottom, the equal fixed mounting in lower left corner and the lower right corner of backup pad 4 has aqua storage tank 7, the equal fixedly connected with limiting plate 8 in both ends about crossbeam 3 bottom, the equal fixed mounting in both ends has spacing seat 9 about base 1 top, the equal opening in inside of spacing seat 9 is provided with spout 901.

Further, limiting plate 8 agrees with mutually with the spout 901 of

spacing seat

9, and 8 bottoms of limiting plate just in time imbed in the spout 901 of spacing seat 9 for when the device is supporting the tunnel top, because the limiting plate 8 imbeds to spacing seat 9 in, spacing seat 9 can prevent that crossbeam 3 from controlling the skew, further improved the support stability of device.
