Abstract
A multifunctional measurement rod for a tunnel comprises a main scale and an auxiliary scale, wherein the auxiliary scale is glidingly arranged on the front surface of the main scale; an expansion rod is arranged on the back surface of the main scale; fluorescent scale marks are carved on the front surfaces of the main scale and the auxiliary scale; and a level bubble is arranged on the top end face of the main scale. The multifunctional measurement rod for the tunnel integrates the functions of a hanging rod of a convergence indicator and a level scale, and is convenient to carry and use.
Description
Technical field
The utility model belongs to a kind of instrument of using at tunnel survey.
Background technology
In tunnel survey, need vault settlement measurement and tunnel measurement of the level at present.When the vault settlement measurement, what steel ruler convergence instrument peg was used all is bamboo pole, owing to be subjected to the restriction of tunnel height, bamboo pole is brought into and taken very inconvenience of tunnel out of.When the tunnel measurement of the level, because the subterranean tunnel limitation in height, the levelling pole that the road surface is used is brought inconvenience into, and can't see the number of degrees clearly in the faint tunnel of light, causes error easily.
Summary of the invention
In order to overcome carrying inconvenience, using inconvenient deficiency of existing tunnel survey instrument, the utility model provides a kind of convergence instrument peg and levelling pole function, tunnel multifunctional measuring bar easy to carry, easy to use taken into account.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of tunnel multifunctional measuring bar, comprise main scale and secondary chi, described secondary chi is slidably mounted on the front of described main scale, and expansion link is installed at the back side of described main scale, the scale of band fluorescence is carved with in the front of described main scale and secondary chi, and the top end face of described main scale is installed air level.
Further, the positive both sides of described main scale are provided with slideway, and the back side of described secondary chi is provided with chute, and described chute is sleeved in the described slideway slidably.
Further again, the front upper of described main scale is provided with draw-in groove, and the lower backside of described secondary chi is provided with the bayonet socket that cooperates with described draw-in groove.
Described main scale is longer than described secondary chi.
Hook is installed at the top of described expansion link.
The beneficial effects of the utility model mainly show: take into account convergence instrument peg and levelling pole function, easy to carry, easy to use.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1～Fig. 5, a kind of tunnel multifunctional measuring bar, comprise main scale 1 and secondary chi 2, described secondary chi 2 is slidably mounted on the front of described main scale 1, expansion link 7 is installed at the back side of described main scale 1, the scale 4 of band fluorescence is carved with in the front of described main scale 1 and secondary chi 2, and the top end face of described main scale 1 is installed air level 5.
The positive both sides of described main scale 1 are provided with slideway 3, and the back side of described secondary chi 2 is provided with chute 8, and described chute is sleeved in the described slideway slidably.
The front upper of described main scale 1 is provided with draw-in groove, and the lower backside of described secondary chi 2 is provided with the bayonet socket 6 that cooperates with described draw-in groove.Described main scale 1 is than described secondary chi 2 length.Hook 9 is installed at the top of described expansion link 7.
According to tunnel monitoring needs, described expansion link 7 is totally six joints, and every joint length is 1 meter, adopts spring bayonet socket 10 to connect between every joint pole, and described hook 9 is fixed on the expansion link top by rotation.
In the present embodiment, sounding rod is divided into main scale 1 and secondary chi 2 two parts, and secondary chi 2 can slide up and down at main scale 1 by chute.When secondary chi 2 glided with main scale 1 merging, sounding rod was convenient for carrying.When needs were measured, secondary chi 2 was upwards sliding and fixing by bayonet socket 6 by chute.Be carved with the scale of band fluorescence on main scale 1 and the secondary chi 2, satisfy the detection requirement under the faint light in tunnel.Main scale 1 back is with expansion link 7, and expansion link 7 is totally six joints, and masthead has hook, and when needing to survey the vault sedimentation, expansion link 7 is used to hang levelling pole and steel ruler convergence instrument.
