Swing is smeared dish and is arranged in finisher cart traffic direction side, first the concrete surface after lining cutting is bulldozed, smooth; Opposite side fixedly smear dish again carry out floating, propose slurry, press polish.When wiping one's face first, concrete surface is softer, should carry out from toe to slope shoulder.The height smearing dish, just to touch concrete surface, is smeared dish and is located in the free state of concrete surface, makes to smear dish and can produce the inclination of 100+30/-20 or float in position, be conducive to being bulldozed and surfacing of gathering materials by floating suspension rod.Smear dish precompression according to concrete surface hardness situation setting during troweling, troweling pressure does not arrange excessive, can not make, in the concrete surface after smearing dish injection lining cutting, to destroy the integrality of plane so on the contrary, stone can be thrown away during rotation.Can not pressure of wiping one's face be established when wiping one's face first, rely on mechanism's deadweight of turning round floating.After single width operation completes, when pushing up to slope, dish will be smeared and promote 50-100mm height, to toe return; The each moving interval of finisher is 2/3 disk diameter, and finisher smears dish diameter 1.2m, and moving interval is no more than 800mm.Open afterwards again and smear disc spins, falling head, to same position, carries out the one way operation of next width.The surface finishing device speed of travel controls to be advisable for 5m ~ 6m/min.Check the planeness of concrete surface in process of wiping one's face at any time with 2m guiding ruler, ensure that smearing the face of trying to get to the heart of a matter overlaps with lining design end face.Finisher height and gradient to be checked when gathering materials, will adjust in time when there is skew; Owe the serious local slurry of material to supplement.The suitable height smearing dish, to touch concrete surface all the time as well, drops on the concrete surface after lining cutting.Downwardly towards on lifting smear dish time, answer limit rotate smear web lifting.Otherwise surface produces impression or smears dribbling material.Smear dish operation simultaneously, highly must adjust consistent for 2 of surface finishing device 22 configuration.In the process of mechanical work, with toe two ends, the position, dead angle of coiling and can not arrive is smeared for top, slope, arrange manually to wipe one's face simultaneously.

Quadric-plastering: after 20 ~ 25min, concrete surface has had some strength, available have gentle hands pressure, during as felt like jelly but leave trace print in surface, just can carry out quadric-plastering in time.To the concrete surface after just smearing again carry out smooth, propose slurry, floating, press polish, with certain repairing effect, remove rough and uneven in surface, surperficial pit and the bubble of local, make concrete surface smooth, smooth, without smearing trace.Increase dense surface degree and planeness.Preset smear dish troweling pressure time, according to the hardness situation on surface from childhood to large adjustment, initial precompression 1.5 ~ 2 times of can be set as that troweling mechanism conducts oneself with dignity, still with smear dish can not penetration concrete surface for principle, strengthen gradually, until obtain best Troweling press finishing effect.Other operation requirements with wipe one's face first identical.

Behind machinery receipts face 2 times, verification is carried out to the effect of wiping one's face and checks and accepts, when only having the area of 80% to reach requirement, after the 20 ~ 25min of interval, third time mechanical receipts face be carried out, until more than 90% surfacing, smooth, nothing obviously smear trace.Can arrange manually to receive face.

The effect in artificial receipts face: omit the position that maybe can not arrive to mechanical work and repair, eliminates and smears dish and significantly smear trace, carry out artificial press polish process to shaping surface, removes blibbing, make concrete surface smooth, smooth, without smearing trace.

Manually to wipe one's face operation on platform of manually wiping one's face, use wood to turn round and iron is turned round cooperation, pressure is smeared to concrete surface, and uses 2m guiding ruler to carry out planeness inspection, whole concrete surface planeness is controlled at 4mm/2m.Be generally 1 ~ 2 time.

Also to carry out press polish process before initial set, remove blibbing.Available have gentle hands pressure, as surface harden but slightly trace print time, just can carry out press polish process in time, eliminate blibbing, pit and vestige of turning round, improve compactness and the smoothness on surface, lower roughness.When estimating concrete close to initial set, receive face press polish and first to be turned round receipts one time by artificial iron, the region wood that locally paste effect is general is turned round subsequent collection 1 time, to be turned round receipts one time more afterwards by artificial iron.During receipts face, turn round and should mutually laminate, eliminate and smear trace.

Concrete maintenance: take geotextiles to cover moisture-keeping maintaining after initial set of having wiped one's face in time.Set up water tank at lining construction scene and carry out water storage, concrete geotextiles covers, and artificial water pipe sprays maintenance.Lining concrete ensures that moist curing is no less than 28 days.After completing growth period, carry out next procedure: cutting shrinkage joint and grouting treatment.Central line tunnel concrete lining in south leaves it at that.2 section the 4th, Middle Line Project For Transferring Water From South To North first stage of the project Jiaozhuo bid section, commencement of works date: on 08 20th, 2009, Practical Completion date: on 03 27th, 2014.Wherein soil property channel overall length 4266.5m, is divided into four element projects, in acceptance on examination, is rated as good degree, concrete lining face acceptance rate 92%.The effect of concrete surface Troweling press finishing, directly determine shaping after surface quality, and the intensity in artificial receipts face and workload.Central line tunnel concrete lining in south hydraulic pressure finisher, with precompression be bulldozed dual effect, ensure that construction quality and task performance satisfactorily.Because south water to north Center Project earthwork bid section is almost constructed in the same time period, what the utility model provided has obvious superiority with the channel being bulldozed effect domatic lining cutting troweling equipment with precompression compared with similar type, awaits applying in large channel lining construction from now on.

The utility model is not limited to above-mentioned embodiment, and when not deviating from flesh and blood of the present utility model, any distortion that it may occur to persons skilled in the art that, improvement, replacement all fall into protection domain of the present utility model.
