Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
As shown in Figures 1 to 4, the side of the keel installation of the invention assisted using total station and three-dimensional laser scanner
Method includes the following steps:
(a) total station is placed on Construction of Steel Structure platform in the shaft, finds the bottom vertical shaft center of circle, passes through laser lead
Hang down instrument, and the bottom center of circle is projected to reception target, total station is positioned.According to construction drawing, each monomer is determined using total station
Position of the keel 11 on vertical shaft inner wall launches 11 central axes of monomer keel on vertical shaft concrete inner wall 41.Single layer unwrapping wire
After, it is hung using row and moves down steel structure platform, repeated the above steps, complete next layer of setting-out work, until entire
Vertical shaft unwrapping wire finishes.
(b) after unwrapping wire, horizontal measurement is carried out by total station, checks whether keel installation region concrete-type face deposits
In error.The region convex to vertical shaft center position drum occurs for concrete-type face, is unsatisfactory for the internal diameter requirement of silencer wall keel group, benefit
Go out error value with total station survey, then the concrete for protruding part is rejected using electric hammer or electric pick, makes keel installation area
Domain meets design requirement.For invagination or satisfactory concrete region, then no longer handled.
(c) after concrete inner mold surface treatment, the noise reduction board keel 11 that anti-corrosion finishes is hung to Construction of Steel Structure platform.
Operator is placed on installation region according to unwrapping wire, by monomer keel 11, and then survey crew utilizes total station survey, makes monomer
Keel 11 are preliminary in place.When measurement, make dragon by 4 control points using 11 upper end two o'clock of keel and lower end two o'clock as control point
Bone 11 is vertical, does not generate the corner along own central axis line.In measurement process, installation personnel continuously adjusts 11 position of keel,
Until meeting drawing requirement.
(d) after monomer keel 11 are preliminary in place, keel 11 are connect with 12 spot welding of ring foundation built-in fitting.Work as ring foundation
When built-in fitting 12 protrudes, adjusts and post-process to the later period.When ring foundation built-in fitting 12 is recessed, the steel plate of cushioning suitable thickness.
When spot welding connects, on the one hand it is noted that careful operation, prevent it is firmly excessive in welding process so that keel 11 are displaced；Separately
On the one hand, it is necessary to ensure that the intensity of spot welding, it is ensured that monomer keel 11 can be fixed safely, prevent to fall, and avoid again a little
Weldering excessively influences subsequent adjustment process.
(e) 11 spot welding of monomer keel connection finishes, and carries out the installation of next keel 11.It is repeated in step (c), (d),
The fixation of keel 11 all in single layer is finished.
(f) it after 11 spot welding of single layer keel is fixed, is scanned using three-dimensional laser scanner.Reply is three-dimensional before scanning
Laser scanner is checked and is verified, and guarantees that scanner is in shape, while flood keel 11 are in three-dimensional laser
The effective scanning range of scanner.Target ball is laid in scanning slice inner wall.Three-dimensional laser scanner is erected at Construction of Steel Structure
Platform middle position, by instrument leveling.Condition depending on the site environment selects suitable scan pattern, resolution ratio and precision, and beats
Open camera, starting scanning.Three-dimensional laser scanner is automatically scanned the layer, and after the end of scan, machine is automatically stopped.It will
Scanning result imports pretreatment software, removes extraneous region and noise spot, carries out pumping analysis, noise reduction process, obtains three-dimensional point cloud
Model.Using 3 d modeling software, 11 threedimensional model of silencer wall keel is established.To reduce workload, the letter of a vertical shaft can be built
Single model is compared with single layer keel group's inner mold face.After three-dimensional point cloud model and vertical shaft model are imported analysis software progress
Processing.Obtain this layer of deviation cloud atlas, extent of deviation can be observed on the whole, then to the type face deviation of each monomer keel 11 into
Row analysis, obtains specific deviation data, provides data for secondary adjustment and supports.
(g) bias contribution provided according to analysis software, to there are the monomer keel 11 of type face deviation to carry out secondary adjustment.
When adjustment, first in one and the position of 12 spot welding of ring foundation built-in fitting, keel 11 are carried out to be fully welded connection.Followed by it discharges
Other spot welding positions are pressed down on when inner mold face drum is convex, while being measured according to deviation Steel Ruler 42, are met the requirements
Afterwards, junction will be closed on to be welded and fixed；When type face recess when, steel chock is inserted into respectively from 11 two sides of keel, with hammer to
Interior hammering, depressed area is jacked up, and two sides measure simultaneously, and junction will be closed on after meeting the requirements and is welded and fixed.It is repeated in, directly
It is adjusted in place to entire keel 11.When ring foundation built-in fitting 12 protrudes, after adjustment and fixed adjacent attachment points, oxygen second is utilized
Alkynes flame cuts off monomer keel 11, according to error value, adjusts cut-off part upper and lower side, and when adjustment is measured using Steel Ruler 42,
In place afterwards by keel 11 to being welded to ring foundation built-in fitting 12.The adjustment of keel 11 is fully welded fixation after meeting the requirements.Deviation conforms to
It asks, directly carries out being fully welded fixation at spot welding position.
(h) all adjustment after the installation is completed, the installation of next layer of keel is carried out according to the step of (c)-(g) to one layer of keel.
It is repeated in, until entire noise reduction board keel group installs.
(i) entire keel group after the installation is completed, carries out entire scan and post-treatment procedures to keel group, it is inclined to obtain type face
Difference, single two-way verticality, the circumferentially deviation informations such as angular displacement and whole concentricity, make and are installed for subsequent acoustical panel
Data are provided to support.
