Wherein the first marker post 1 has a scale value arranged along its extension direction. Second sighting rod 2 is on a parallel with first sighting rod 1, and second sighting rod 2 detachable connects in first sighting rod 1 to second sighting rod 2 can slide along the extending direction of first sighting rod 1, and second sighting rod 2 has reading mark 4.

In the initial state, the reading mark 4 corresponds to a first scale value, and when one end of the first mark post 1 abuts against the fixed end 31 and one end of the second mark post 2 abuts against the telescopic end 32, the reading mark 4 corresponds to a second scale value. The difference between the second scale value and the first scale value is the expansion amount of the bridge damper 3.

Specifically, the length of first sighting rod 1 and second sighting rod 2 all can be set for according to actual need, guarantees that survey crew can stand in safe position, measures bridge damper 3's flexible volume. Preferably, the first marker post 1 may be longer than the second marker post 2, ensuring that the second marker post 2 does not slip out of the first marker post 1. The cross section of the first marker post 1 and the second marker post 2 can be rectangular, circular and the like. Preferably, the first marker post 1 and the second marker post 2 are the same in shape, so that the measurement and the storage are convenient.

Specifically, the second marker post 2 may be located above the first marker post 1, or may be horizontally arranged side by side with the first marker post 1. When first sighting rod 1 and second sighting rod 2 need dismantle, slide first sighting rod 1 along the extending direction of second sighting rod 2, until the draw runner roll-off spout of first sighting rod 1.

In particular, the reading mark 4 may be adjacent to the end of the first mark post 1, or may be located in the middle of the first mark post 1. Preferably, the reading mark 4 and the scale value are in the same plane, so that the reading is convenient. In the embodiment of the present application, the reading mark 4 is a triangle, and the tip of the triangle points to the scale value, and in other embodiments, the reading mark 4 may be other shapes such as a vertical line.

Further, the first marker post 1 has a first abutting portion 12 for abutting against the fixed end 31, and the scale value of the first marker post 1 gradually increases from one end far away from the first abutting portion 12 to the other end from zero scale value. In the initial state, the reading mark 4 corresponds to a zero scale value.

Specifically, in the initial state, the reading mark 4 corresponds to a zero scale value, and when the end of the second marker post 2 abuts against the telescopic end 32 of the bridge damper 3, the scale value corresponding to the reading mark 4 is the telescopic amount of the bridge damper 3, and the measuring method is simple and rapid.

In some embodiments, the reading mark 4 may not correspond to a zero scale value in the initial state.

Further, the first marker post 1 includes a first body 11 and a first abutting portion 12 formed by bending one end of the first body 90 degrees to one side, and the second marker post 2 includes a second body 21 and a second abutting portion 22 formed by bending one end of the second body 90 degrees to one side.
