| description | The utility model discloses a tunnel section steel frame web trepanning positioning fixture which comprises a fixture body, the fixture body is in an arc shape, the bending radian of the fixture body is consistent with that of tunnel section steel, and the extension length and the width of the fixture body are both smaller than those of a web of the tunnel section steel. The inner arc of the clamp body can be attached to an inner wing plate of tunnel profile steel or the outer arc of the clamp body can be attached to an outer wing plate of the tunnel profile steel, at least two positioning holes are formed in the clamp body at intervals, and the spacing distance between the two positioning holes is equal to the spacing distance between two adjacent advanced small guide pipes needing to be inserted into the tunnel profile steel. When the right end of the clamp body abuts against the inner wall of the right end of the tunnel profile steel, the first positioning hole in the right side just corresponds to the hol |
