Problems solved by technology

In the case of a long line of sight or turbid air in the underground structure space, the sighting error is relatively large, and even the sighting is difficult. When the distance of the monitoring area is long, the magnification of 30 times cannot meet the reading requirements
The polar coordinate method also needs to use a high-precision total station for measurement, but there are errors in the actual angle measurement and distance measurement process, so the measurement accuracy is low, and it is only suitable for horizontal displacement monitoring work with low precision requirements

Abstract

The invention provides a laser measuring device for monitoring the horizontal displacement of a comprehensive pipe gallery. The laser measuring device comprises a laser transmitter, a support system and a scale baffle system. The laser transmitter is fixed in a static area of the utility tunnel and is used for providing a laser beam; the support system comprises a plurality of brackets and is used for mounting the scale baffle plate system; and the scale baffle system is composed of a plurality of scale baffles with scales and used for measuring the horizontal position of the laser beam on the scale baffles. The invention further provides a using method of the laser measuring device.

Description

Technical field [0001] The present invention patent relates to a laser apparatus and method for measuring the utility tunnel horizontal displacement monitoring. Background technique [0002] With the construction and development of cities, large numbers of people flock to the construction of urban rail transit, underground utility tunnel, high-rise building become the main theme of urban construction, more and more of the excavation works in densely populated urban areas . In the process of deep foundation excavation, the soil subsidence and displacement of the surrounding, normal use and safe operation of the structures built around a challenge, especially near the underground pipeline Gallery and other long linear structures. Thus ensuring both during construction excavation safety of underground utility tunnel is particularly important, by analyzing the monitoring data, to master the changes of the structural stability of the pipe gallery, always adjust the sequence of constru...
