Abstract
The utility model relates to a measuring and locating device which is characterized in that: the middle part of a ruler is provided with leveling bubbles and a measuring target; and two ends of the ruler are provided with lengthening rulers. When in use, the measuring and locating device can judge whether the ruler is in a level state through the leveling bubbles; the length of the measuring device can be set by a connecting device and the lengthening rulers according to actual requirement. The measuring and locating device can directly and conveniently demarcate the center of a tunnel plane, thereby being capable of efficiently and directly measuring the plane position of the central line of a tunnel; meanwhile, the measuring and locating device is convenient for carrying and can reduce the requirement on apparatuses and improve the measuring efficiency and precision.
Description
Technical field:
The utility model relates to the fields of measurement of Tunnel Engineering, a kind of specifically auxiliary locator of measuring shield tunnel midline plane position.
Background technology:
The measurement of shield tunnel midline plane position is to detect one of important indicator of Tunnel Engineering quality, because the center, tunnel is difficult for directly demarcating, conventional method is to utilize the non-prism total powerstation of band motor driven to carry out the full tunnel cross-section data acquisition of 360 degree according to certain intervals, simulate the center line in tunnel then, determine the method for the horizontal level of shield tunnel center line; This method equipment needed thereby cost on the one hand is higher, detects the frequency height, and workload is big, and the instrument and equipment that needs is more; The data volume of Ce Lianging is very big on the other hand, and work efficiency is not high.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved auxiliary locator that is used to measure shield tunnel midline plane position, and it is higher that it can overcome in the prior art cost, detects the frequency height, and workload is big, and the instrument and equipment that needs is more; Simultaneously-measured data volume is very big, the some shortcomings that work efficiency is not high.
To achieve these goals, the technical solution of the utility model is: a kind of measurement and positioning device, it mainly comprises ruler, it is characterized in that: the middle part of ruler is provided with leveling bubble and measures target, and the two ends of ruler are provided with and add long ruler.
During use, the utility model can judge whether ruler is in horizontality by leveling bubble, and the length of measurement mechanism can be provided with by coupling arrangement and lengthening chi according to actual needs flexibly.Can demarcate planar central position, tunnel in direct convenience ground, thereby can directly measure the planimetric position of tunnel center line expeditiously, can be convenient for carrying simultaneously, can reduce requirement again, improve efficient and the precision measured instrument and equipment.
Description of drawings:
Fig. 1 is the structural representation of the utility model one embodiment
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises ruler 1, and its difference with the prior art is: the middle part of ruler is provided with leveling bubble 2 and measures target 3, and the two ends of ruler are provided with and add long ruler 4.Add long ruler and form movable the connection with ruler by web member, add long ruler and be provided with connection keyhole 5, the two ends of ruler are provided with and are connected the corresponding connecting hole of keyhole.Measure the center that target is arranged on ruler, leveling bubble is arranged on apart from 30cm place, ruler center.Ruler adopts aluminum alloy material to make, and is hollow structure, but also can adopts other that material of effect same is arranged in practice.
In force, when the ruler two ends were placed tunnel inwall and ruler level, ruler planar central position overlapped with central plane position, tunnel, measured the planimetric position that target placement that this device installs can obtain the center, tunnel this moment.Can change ruler length to adapt to the tunnel of different-diameter by the coupling bar hole site that the adjusting two ends add on the long ruler.The utility model has good operability in material and enforcement simultaneously.
