A kind of installation method of twisted steel positioning reinforcing device, includes the following steps：
The first step, in Construction in Preparatory Stage, according to the construction location and angle of positioning threads muscle, the steel arch in leading hole
Fixing steel plate one and fixing steel plate two is respectively welded in the both sides of frame one；
Second step after the completion of steel arch-shelf one is set up, utilizes the fixing steel plate one and positioning being welded on leading hole steel arch-shelf
Preformed hole on steel plate two carries out drill precise holes；
Third walks, and in the upper casing of spiral end point set of composition steelframe, and spiral is squeezed into along drilling, is covered
The gap of pipe end and spiral is filled with hot melt adhesive, and steelframe is welded together to form after spiral tail portion is docked；
4th step, heating muff end and the hot melt adhesive in screw-thread steel gap, the casing on twisted steel are removed, leading hole
The spiral in Hou Hangdong top bar outline excavations is extended to, steel arch-shelf two is erected in Hou Hangdong；
5th step is arranged fixing steel plate three in side of the steel arch-shelf two far from country rock, spiral is packed into fixing steel plate
It is welded and fixed in preformed hole on three, and end is bent.
The utility model has the beneficial effects that：
1, row hole after leading hole steel arch rack position ensures is accurately positioned when row hole sets up steel arch-shelf after the utility model enables
Preliminary bracing is completely enclosed；
2, the utility model can enhance the connection between leading hole and rear row hole steel arch-shelf, improve supporting construction stress,
The stability in row hole after raising；
3, the utility model convenient material drawing, mounting process is simple, can effectively simplify constructing tunnel difficulty.
