First support plate 13 is hinged on pull-up steelframe 1, the other end is then slidably connected in the sliding slot 12 of the first transverse slat 15, and then
Sliding panel 16 is placed in sliding in sliding slot 12, can be drawn simultaneously by manpower in the side of installation securing plate 18 at this time
It is dynamic, and the other side then passes through promotion sliding panel 16 and makes the first support plate 13 that protection mechanism be pushed to move up, until first group
When protection mechanism is adjusted to designated position, the second transverse slat 35 is installed again on the fixed frame 5 of 18 side of securing plate, and
The second support plate 30 is placed between two transverse slats 35 and steelframe 1；The fastener 11 of steelframe 1 and adjustable plate 6 is dismantled to steelframe 1 simultaneously
Height be adjusted, i.e., the height of preliminary protection mechanism is adjusted, steelframe 1 and adjustable plate 6 is then passed through into fastening again
Part 11 pre-tightens, and finally splash guard 20 and deflector 21 are sequentially arranged at below preliminary protection mechanism, forms one tentatively temporarily
Suspension device, the rotation for then carrying out above step to the preliminary protection mechanism that another set needs to adjust again are adjusted, are formed
Another preliminary temporary support device；
(3) two temporary support devices tentatively regulated in step (2) installation and adjustment in hole: are individually positioned in movement
On trolley 22, moving trolley 22 is pushed in Tunnel, until it is moved to the designated position of preliminary temporary support device installation,
The height of two groups of protection mechanisms is adjusted to tunnel inner wall is touched respectively, the steelframe 1 on protection mechanism is fixed again,
Finally the support frame 24 on 22 bottom plate 23 of moving trolley is put down, is anchored on tunnel ground, completes temporary support device in hole
Interior installation secured adjusted；
(4) hole inner waterproofing is arranged: the splash guard 20 in step (3) on mounted temporary support device is turned to properly
Behind position, the deflector 21 on splash guard 20 is put down, the installation site of deflector 21 is found, then using auxiliary tool in tunnel
Resettlement groove is excavated out on road ground, and excavates drainage trough in the outflow end of resettlement groove, and drainage trough leads to outside tunnel, finally by water conservancy diversion
Plate 21 is placed in resettlement groove.
