Description
Technical field
The present invention relates to a kind of concrete surface processing unit and methods, and in particular to a kind of vertical shaft slide model concrete press polish
Device and calendering method.
Background technique
With the continuous improvement of national economy level, electric utility both domestic and external is also had been greatly developed；Power station
Occupy very big specific gravity in power industry, construction quality has important influence for the production of electric power enterprise；Water channeling type
The positions such as diversion tunnel, surge shaft, power tunnels, the power tunnel vertical shaft in power station are frequently with concrete lining structure；Sluicing is built
The out-of-flatness for building object surface has more significant impact to cavitation corrosion cavitation inception, and cavitation corrosion is that waterpower industry is dedicated to avoiding or subtract
Weak phenomenon.
With the continuous development for having run-of-river power station to build, the new work of new technology is continued to bring out in diversion tunnel lining construction
Skill, Water diversion tunnel concrete construction quality are continuously improved；The permanent operational safety of engineering is promoted, largely improving to extend makes
With life cycle, operation maintenance cost has been saved.
Built engineering operation practice have shown that, even if design is accurate, the advanced science of material, proportion design, construction technology is stringent；
After longtime running, the concrete surface quality problem of construction period will gradually amplify under time dimension, sluice, diversion
Building concrete total surface has different degrees of abrasion and cavitation corrosion.
Diversion tunnel lining construction mainly uses trolley segmentation one-off construction to pour both at home and abroad at present, and power generation vertical shaft is adjusted
Kill-job etc. is frequently with form construction technology.The quality of the cast-in-place lining concrete construction quality of sliding formwork, directly influences reinforced concrete
Bearing capacity, durability and the globality of soil structure, therefore each construction link must be done a good job of it in construction, to ensure concrete
Construction quality.Appearance quality trait after sliding formwork or the demoulding of needle beam trolley template is to be related to building surface beauty and knot
The critical process of structure quality；Sliding formwork cast-in-place concrete demoulding after initial set be surface-treated in time during final set, certain journey
Fabric structure quality can be improved on degree.Moulding contraction fissure and subtle stomata especially are handled in concrete setting getting up early,
Improving concrete integral smoothness reduces surface roughness, can weaken hydraulic structure cavitation erosion to a certain extent.
Germany professor Uwe Drewes summarizes some engineerings in the world since cavitation occurs for irregularity degree, cavitation corrosion is asked
Topic；The cavitation property for analyzing some out-of-flatness surfaces, when also making various values different in flow rate, the appearance of uneven entirety upstream face
Perhaps the gradient has also been proposed to the requirement of smooth concrete surface and guarantees the measures such as air mixing corrosion reducing.
Weakening control measure to cavitation corrosion both at home and abroad at present is mainly four aspects: selecting reasonable overcurrent side when (1) designing
Wall body type；(2) flatness improved construction technology, improve overcurrent side wall；(3) the stronger material of etch resistant properties is selected；(4) aeration
Corrosion inhibitor.Wherein in terms of the flatness for improving construction technology raising overcurrent wall, often improved again after concrete formation smooth
Degree, finish do not propose effective technological measure.Only occurs the work handled about press polish in building construction or pavement concrete
Skill technology, and waterwork is more in the industry from concrete proportioning, template and vibrates etc. and to improve concrete finish
And flatness, do not have also to the technique for doing press polish processing after concrete surface demoulding, to diversion tunnel and power tunnel vertical shaft circle
Shape or arc-shaped sections do anaphase effect processing almost without.
In the construction of power station power tunnels vertical shaft slide model, concrete surface finishing processing is newly skidded off, is to be related to knot
The process of structure appearance and protective layer quality must carry out concrete surface processing work immediately after concrete demoulding.But at present
About the treatment measures after demoulding in existing construction technology, magma manually only is done to the apparent mass defect in part and flattens or repairs
It is handled, is that smooth being generally not processed only need to reinforce maintenance for visual examination, not to early stage moulding
It shrinks micro-cracks, tiny stomata etc. and does system overall treatment.
Summary of the invention

Slap curvature.General value is 45 ° ~ 60 ° range values, weight at a slow speed when go to be worth greatly, get the small value when low pressure is quick；Selection is suitable
7 revolving speed of walking dolly, general value range is in 15 ~ 30m/s；
Step 3: after the demoulding of 1 upward sliding of vertical shaft slide model, starting walking dolly 7, arcuately track 8 is moved through walking dolly 7
Journey, cement slurry slurries spray to vertical shaft inner wall 4 by shower head pipe 906, carry out first pressing by press polish piece 501；First pressing should select compared with
Slow speed carries out, and general first pressing carries out one time；It is suitably filled spray slurries according to concrete surface pulp situation, it can be according to practical feelings
Locally supplement smears pressure to condition；Cement slurry has spray equipment 9 to pressurize even application to corresponding concrete surface, and spray range is press polish piece
501 contact points to front end 10cm or so.
Step 4: after the completion of first pressing, being pressed in progress；Middle pressure selection middling speed contacts twice of press polish, and middling speed press polish is preferably used to make
Industry；
Step 5: being carried out before cement slurry slurries final set, reduce by 7 speed of walking dolly and carry out receipts light；Appearance is carried out after the completion of middle pressure
Quality checks that last pressure-sizing one time, light processing is quickly received in the small contact of 30min before final set comprehensively.
It is different according to building concrete match ratio and intensity, select different press polish time interval and corresponding speed
Rate, the too early or too late quality problems that can all cause concrete surface dusting, play ash；Before first pressing, firstly for local defect
Obvious position uses manual type precompressed repairing treatment.
The operating condition of the artificial plastering metope of present invention simulation, using equipment connecting rod drive plasterer's trowel to newly pour metope into
Row press polish plastering substitutes artificial realization mechanization, and the accurately press polish plastering for completing the system of young concrete large area is applied
Work.When press polish, press polish piece 501 at the uniform velocity rotates on planned orbit along concrete surface with one heart, and concrete surface and press polish piece 501 squeeze
Pressure friction generates slight plastic deformation, the microdefects such as micro-cracks, bubble by newly-laid concrete magma under press polish effect
Press polish is filled and led up, achievees the purpose that improve finish and flatness so that the surface of subtle injustice be made further to obtain improvement.
