after the first bracket 1 and the second bracket 2 are placed, the first bracket 1, the second bracket 2 and the beam 33 are kept in a vertical state, at this time, two ends of the connecting rod 52 can be respectively placed on the two fixing seats 51 on the first bracket 1 and the second bracket 2, which are positioned on the same side, then two ends of the connecting rod 52 can respectively slide into the limiting grooves 55 on the two fixing seats 51, because the two limiting grooves 55 are L-shaped, after the two ends of the connecting rod 52 are placed into the two limiting grooves 55, one end distance can horizontally slide towards the inside of the limiting groove 55, at this time, the connecting rod 52 can be fixed only by rotating the limiting blocks 54 on the two fixing seats 51 and respectively inserting the two limiting blocks 54 into the two limiting grooves 55, because the two ends of the connecting rod 52 are respectively positioned at the positions close to the inner sides of the two limiting grooves 55 after the connecting rod 52 is installed, therefore, the connecting rod 52 can be taken out from the fixing seat 51 only by moving horizontally, after the two limit blocks 54 are inserted into the two limit grooves 55, the connecting rod 52 is taken out from the limit grooves 55 and is released from being fixed, only the connecting rod 52 can rotate in the vertical direction, the connecting rod 52 only can apply horizontal thrust to the limit blocks 54, the limit blocks 54 are difficult to rotate in the vertical direction under the condition of no artificial rotation, therefore, the connecting rod 52 is fixed in the two limit grooves 55, and the two connecting rods 52 are arranged, so that the first bracket 1 and the second bracket 2 are in a relatively fixed state after the two connecting rods 52 are fixed, thereby the whole supporting device is in a fixed state and is not easy to shake; because the two ends of the first support 1 and the second support 2 are both rotatably connected with two rotating rods 72, and each rotating rod 72 is fixedly connected with a rotating plate 73, the two ends of the first support 1 and the second support 2 can be fixed by inserting the rotating plates 73 into the ground surface in the roadway, when the two rotating plates 73 respectively rotate along with the two rotating rods 72 by taking the two round rods 71 as axes, the two rotating plates can be slowly inserted into the ground surface in the roadway, the end surfaces of the rotating plates 73 are sharp, so that the first support 1 and the second support 2 can be more easily inserted into the ground surface, the rotating plates 73 have a radian, when the rotating plates 73 are inserted into the ground surface by rotation, the rotating plates are not vertically downwards inserted, but inserted by a certain radian, therefore, after the rotating plates 73 are inserted into the ground surface in the roadway, the rotating plates 73 are not easy to be pulled out of the ground surface by vertical pulling or horizontal pulling, and under the action of the four groups of rotating plates 73, the first support 1 and the second support 2 can be firmly fixed on the ground in the roadway; after whole strutting arrangement installs, can drive screw rod 62 and rotate through rotating carousel 61, screw rod 62 rotates, can the downstream, screw rod 62 moves down and drives two rings 64 downstream, drive slide 65 downstream when two rings 64 move down, slide 65 can push down two bull sticks 72 during the downstream, bull stick 72 is pressed down and will rotate, and bull stick 72 rotates and can drive revolving plate 73 to rotate, thereby drive revolving plate 73 and insert soil, finally make first support 1 and second support 2 fix subaerial in the tunnel.
