Abstract
The utility model discloses a bridge body longitudinal displacement observation device, and belongs to the technical field of the tachymetfering. The bridge body longitudinal displacement observation device is characterized by including a pointer and a graduated scale; the graduated scale is horizontally installed on a bridge body; the pointer is fixed on a base; the base is fixed a bridge pier top at one side of the bridge body; and the upper head of the pointer is provided with a pointer tip pointing to the middle position of the graduated scale. A lower part of the pointer is vertical to the base; the upper head of the pointer bends towards the graduated scale; and the pointer horizontally points to the middle position of the graduated scale. The bridge body longitudinal displacement observation device can, for a long time, observe the longitudinal displacement of the bridge body relative to the bridge pier top; the observation scale is simple in installation, does not need connection with the power supply, is free of external interference, is not restricted by the terrain, and does not affect the normal operation of the railway bridge; and in the daily inspection process, the displacement value of the bridge can be accurately observed.
Description
Technical field
The utility model relates to a kind of bridge beam body length travel observation device, belongs to tacheometric survey technical field.
Background technology
In the existing standard < < of the railway railway bridge deteriorated evaluation criteria > > of tunnel buildings and < < railway bridge tunnel buildings repairing Regulation G reatT.GreaT.GT >, there is pair relevant regulations of beam body length travel, because the length travel of beam body is the process of a secular variation, observation time is long, disturbing factor is many, cannot accomplish in practice at present to stablize, measure accurately beam body vertical shift.
In prior art, the measurement of beam body length travel is mainly adopted to displacement meter, dial gauge and other photoelectric displacement measurement mechanism etc., these instrument and equipment Installation and Debugging are comparatively complicated, fragile, mostly need to support the use with other collecting device, easily be subject to the impacts such as power supply, external interference and field extreme environment, be used for short-term and measure, inapplicable long-term observation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bridge beam body length travel observation device, have simple in structure, easy for installation, observed reading accurately, feature that can long-term observation bridge beam body length travel state.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of bridge beam body length travel observation device, is characterized in that: comprise pointer and rule; Described rule level is arranged on Liang Tishang, and described pointer is fixed on base, and described base is fixed on the bridge pier Dun Ding of beam body one side, and pointer upper end head is provided with pointer tip and points to the middle position of rule.
The further improvement that the utility model is done is: described pointer bottom is vertical with base, and pointer upper end head is towards the bending of rule direction, and its pointer tip level is pointed to the position in the middle of rule.
The beneficial effect that adopts technique scheme to produce is: the utility model can be observed the vertical shift of the relative bridge pier Dun Ding of beam body in current check process; This sight gauge install simply, do not need to access power supply, external interference little, not limited by landform, do not affect the normal operation of railway, can accurately observe the shift value of bridge.
