The outer end of described positioning pipe is fixed on the below of arc Horizontal Cantilever horizontal segment by gusset, andThe inner of positioning pipe and arc Horizontal Cantilever oblique arm section are fixed together; The inner of described positioning pipe withBetween arc Horizontal Cantilever oblique arm section, be fixed with connecting plate, and connecting plate is positioned at the below of positioning pipe,The upper end of described inclined cantilever is hinged on connecting plate.
The below of passing through uniform gusset and be fixed on arc Horizontal Cantilever horizontal segment of described positioning pipe,And the inner of positioning pipe and arc Horizontal Cantilever oblique arm section are fixed together; The inner of described positioning pipeBelow is fixed with connecting plate, and the upper end of described inclined cantilever is hinged on connecting plate.
The advantage that the present invention compared with prior art has and effect:
1, the arc Horizontal Cantilever oblique arm of the present invention section is close to tunnel wall installation, Horizontal Cantilever is installed solidFixed point moves down, and then makes bracket entirety along continuous straight runs close to tunnel wall to greatest extent, structureCompactness, has saved installing space, can meet the little space mounting requirement of low headroom tunnel completely,No matter be at low headroom tunnel straightway or curved section all can meet boundary requirement.
2, the present invention is by arc Horizontal Cantilever oblique arm section termination, inclined cantilever termination and tunnel davitThe adjustment of link position, has realized the movement in the horizontal direction of bracket integral position, makes bracket wholeBody along continuous straight runs is pressed close to tunnel wall to greatest extent, has not only further saved installing space, andAnd it is more convenient to make to install adjustment, adjusts leeway larger.
3, inclined cantilever of the present invention and horizontal location pipe adopt and are hinged, both carryings for convenience detach,Also be convenient to site operation and install, particularly can realize the adjustment to bracket system water Pingdu.
4, to be arranged on respectively arc Horizontal Cantilever and level fixed for Messenger Wire base of the present invention, positioning supportPosition pipe is upper, makes bracket entirety stress equalization, and structure is compacter, and then has improved the whole of bracketBody intensity and rigidity, reliability is high.
