Description
Technical field
The invention belongs to shield tunnel construction technology fields, are related to a kind of method for measuring shield tunnel gap of the shield tail.
Background technique
Recently as urban rail transit in China fast development, shield method is more and more applied due to its plurality of advantages
In urban tunnel construction.In shield tunnel construction, shield machine controls tunneling direction by control cylinder jack stroke,
And in practical Shield Construction Method Used, shield driving has certain deviation, and it often results in gap of the shield tail and changes, gap of the shield tail
When too small, it be easy to cause shield tail brush to draw section of jurisdiction outer wall and causes section of jurisdiction faulting of slab ends or breakage, when shield tail brush wear is serious, and can destroy
Tail sealing system, to a series of engineering problem occur.Therefore, gap of the shield tail is quick and precisely measured in real time, for shield
The quality and progress of structure constructing tunnel have important meaning.
The gap of the shield tail measurement method that construction site mainstream uses at present still based on manual measurement, although there are also
New technology and measurement method, but be difficult to apply in practical projects, such as a kind of laser ranging system, which is by laser
Range finder is fixed on duct piece assembling machine, drives airborne laser range finder to be moved to when duct piece assembling machine rotates assembled good in shield shell
Section of jurisdiction position, by measurement airborne laser range finder to the radial distance of section of jurisdiction inner wall, then duct piece assembling machine is moved in shield shell not
Segment assembly position, the radial distance of measurement airborne laser range finder to tail shield inner wall, difference of the two between subtract section of jurisdiction again
Thickness is gap of the shield tail.But since duct piece assembling machine is without the position of suitably installation airborne laser range finder, it is difficult to guarantee to survey
Obtained airborne laser range finder is measured radially to survey to the distance of tail shield inner wall and the distance of airborne laser range finder to section of jurisdiction inner wall
Amount, there is also measurement errors for airborne laser range finder itself, so the final gap of the shield tail value error for calculating acquisition is larger；Another example
Son is a kind of gap automatic range unit (CN 108613632.A), which is fixed on shield shell inner wall, utilizes spring and laser
The assembling such as ranging, by the available gap of the shield tail of simple computation, but is easily damaged in pipe sheet assembling, while in face of intricately
When matter condition, which is also difficult to play a role, such as in the more stratum of underground water, and tunnel arch bottom ponding is more, and companion
There are many silts, laser ranging system is just difficult to measure the gap of the shield tail of tunnel arch bottom.
In shield tunnel tunneling construction, the measurement common method of gap of the shield tail is the ordinary steel that civil engineer uses 50cm
The section of jurisdiction inner wall thickness of ruler measurement eight positions of " rice " font subtracts section of jurisdiction thickness and just obtains gap of the shield tail, man-hour manually hand-held ordinary steel
Ruler measurement error is larger and extremely inconvenient in the measurements, thus there is many security risks, while common survey steel ruler makes
The problem for being inconvenient to read or all error being caused larger due to tunnel arch bed mud water is more etc. in, it is based on problem above
The multiple function apparatus for devising a kind of measurement gap of the shield tail convenient for man-hour manually hand-held, can significantly improve measurement accuracy, reduce and miss
Difference.
