It is an object of the invention to provide a kind of rectangular shield phase of boring tunneling boring deformation monitoring method, solves tradition prison Survey method has that efficiency is low, precision is poor.
To achieve these goals, the technical scheme is that:
Rectangular shield phase of boring tunneling boring deformation monitoring method, comprises the steps:
The measurement of the non-erection stage of step one, lining segment:
First step lining segment is by place above crane ground on the scene, and lining segment periphery sets up 2-3 target,
Second step carries out comprehensive scanning using spatial digitizer to each piece of lining segment,
3rd step forms the scanning point cloud model complete per block lining segment by splicing target,
After the completion of all lining segment scannings of 4th step, the splicing of an endless tube piece is completed using virtual connecting method, finally Domain lining segment scanning point cloud model is formed, so as to obtain three-dimensional dimension of the domain lining segment before actual installation;
Measurement after step 2, lining segment installation:
Ground monitoring is controlled net pilot measurement to the target in shield machine working shaft by the first step,
In second step tunnel, target is set,
3rd step arranges spatial digitizer in correct position, and backsight point is target spot, to carry out domain scanning;
The Monitoring Data of step 3, comparison step one and step 2, relative analyses lining segment is in non-erection stage and peace Deformation after the completion of dress.
Further, using three station scan patterns respectively on lining segment lower left, the lining segment right side in the step one Lower section, three directions of lining segment rear upper carry out comprehensive scanning to same lining segment.
Further, two station scan patterns are adopted in the step 2, is spliced by target, to same lining segment Carry out domain scanning.
Further, the spatial digitizer is three-dimensional laser total powerstation.
Further, in the step 2, correct position is the position in target and shield transversal lines line.
Compared with prior art, the invention has the advantages that and beneficial effect:The rectangular shield phase of boring of the present invention Tunneling boring deformation monitoring method, is monitored to lining segment in two stages, first when lining segment reaches construction site First piecemeal carries out the collection of lining segment three-dimensional data and obtains initial deformation of the erection stage lining segment after soil pressure is subject to Value;Then measured while gathered data obtains the shield-tunneling construction stage again after lining segment is installed and forms a domain Deformation values of the lining segment after soil pressure is subject to i.e. after lining segment installation;Before and after being installed according to lining segment Date comprision lining segment be installation in non-erection stage and shield-tunneling construction stage after deformation.The monitoring side Method is by being split as, by the deformation monitoring of rectangular shield phase of boring lining segment, the change that lining segment installs former and later two stages Shape is monitored, and such that it is able to obtain multi-ring lining segment deformation data at short notice, is not being pacified according to relative analyses lining segment Deformation after dress stage and installation, realizes the deformation monitoring of rectangular shield phase of boring full section of tunnel.The monitoring Method is easy to operate, low cost, solves that conventional monitoring methods monitoring efficiency is low, and the poor problem of Monitoring Data precision has Preferable promotional value.
