Description
Technical field
The present invention relates to a kind of construction detection device and application methods, and more specifically, it relates to a kind of tunnel arches
Push up sinking plumb bob observation device and application method.
Background technology
Deformation observation and monitoring measurement are the quality of work progress and the emphasis of security control during constructing tunnel, in tunnel
In road construction, the deformation and displacement of periphery displacement, vault sinking, ground settlement and surrounding building and pipeline are monitoring measurements
It must survey project, wherein vault sinking conventional observation method is that tape measure link is suspended to vault sinking to measure on hook, using spirit level,
Elevation is measured to obtain vault elevation numerical value.Such method by tape measure link hang up monitoring hook the step for take it is too long, 24
Monitoring point took close to 4 hours, and efficiency is low.The effect of vault sinking numerical value is when vault sinking rate of change is very fast,
It is possible that constructing tunnel is just faced with the danger that vault caves in.When vault sinking cumulative amount is excessive, then need at the beginning of changing tunnel
Branch supporting parameter carrys out strengthening supporting, ensures construction in later period safety.Also have and paste total powerstation reflecting piece using on vault sinking hook, make
The rate of deformation is determined by the comparison of height difference with total station survey elevation.By spirit level and total station observation method,
The measurement of people repeatedly is measured, it is longer to expend the time.In recent years, also had using sensor method, and be digitized observation deformation values, this
Kind method control is more convenient, but sensor economy is not strong, considers that economic benefit does not use generally in most constructing tunnels, or
It is not high using frequency, the requirement of safety and quality management cannot be reached.When tunnel vault happen suddenly displacement it is larger when, because use
The unpredictable emergency situations of traditional measurement method face prodigious safety problem in construction personnel constructs at the scene, to
It is difficult to predict be the problem that technical staff and safety quality management personnel explore all the time.
