Description
Technical Field
The utility model relates to a sleeve straightness that hangs down detects technique in tunnel construction specifically is a tunnel sleeve straightness that hangs down detects instrument.
Background
When the embedded sleeve is adopted for installation construction in a tunnel, in order to judge whether the embedding of the sleeve is qualified or not, the perpendicularity of the sleeve needs to be detected (if the sleeve is perpendicular to the tunnel wall, the embedding of the sleeve is qualified, otherwise, the embedding of the sleeve is unqualified). The traditional detection mode is to directly observe the verticality of the sleeve by naked eyes. Practice shows that the detection mode is difficult to meet the detection requirement of the perpendicularity of the sleeve, so that the installation and construction quality is seriously influenced. Therefore, a tool special for detecting the perpendicularity of the sleeve needs to be invented, so that the problem that the detection requirement is difficult to meet in the traditional sleeve perpendicularity detection mode is solved.
Disclosure of Invention
The utility model discloses a solve traditional sleeve straightness detection mode of hanging down and be difficult to satisfy the problem that detects the requirement, provide a tunnel sleeve straightness detection instrument that hangs down.
The utility model discloses an adopt following technical scheme to realize:
a tool for detecting the perpendicularity of a tunnel sleeve comprises a first transverse strip plate, a second transverse strip plate, a graduated scale, a nut and a screw rod; wherein, the center of the plate surface of the first transverse lath is provided with a circular hole which is communicated up and down; the second transverse lath is positioned above the first transverse lath, and the central line of the second transverse lath is superposed with the central line of the first transverse lath; the plate surface of the second transverse lath is provided with a transverse slotted hole which is communicated up and down, and the central line of the transverse slotted hole is superposed with the central line of the second transverse lath; the length of the transverse strip hole is greater than that of the first transverse strip plate; the number of the graduated scales is two; the two graduated scales are bilaterally and symmetrically vertically fixed at two ends of the upper plate surface of the first transverse batten, and the scale surfaces of the two graduated scales are flush; the two graduated scales can slidably penetrate through the transverse bar holes; the upper end surface of the nut is fixed with the lower surface of the second transverse lath, and the central line of the nut is superposed with the central line of the transverse lath hole; the upper end of the screw rod is screwed in the nut, and the screw rod can slidably penetrate through the round hole.
When the device is used, the lower end of the screw is firstly screwed into the sleeve, then the two ends of the first transverse lath are tightly attached to the tunnel wall, then the scale values aligned with the upper plate surface of the second transverse lath on the two scales are observed, and the observed scale values are compared. If the two scale values are equal, the fact that the sleeve is perpendicular to the tunnel wall is indicated, and therefore the fact that the sleeve is embedded in a qualified mode is indicated. If the two scale values are not equal, the sleeve is not vertical to the tunnel wall, and therefore the sleeve is unqualified in embedding.
Based on above-mentioned process, compare with traditional sleeve straightness detection mode that hangs down, a tunnel sleeve straightness detection instrument that hangs down through adopting brand-new structure, realized accurate, fast to telescopic straightness that hangs down detect, can satisfy the detection requirement that the sleeve hangs down from this to showing and having improved installation construction quality.
The utility model discloses rational in infrastructure, design benefit have effectively solved traditional sleeve straightness detection mode of hanging down and have been difficult to satisfy the problem that detects the requirement, are applicable to the sleeve straightness that hangs down of various specifications and detect.
