Detailed description of the invention
As in Fig. 1-4, the sliding shuttering of the utility model patented technology is primarily of compositions such as template system, trailer system, the anti-bias system of anti-floating, concrete warehousing vibrating system, defect elimination curing systems.
1, template system: primarily of panel, ribs, support enclosure composition; Panel can adopt 6-9mm steel plate to process or firm template assembly of shaping, and forms rigid structures by shaped steel enclosure, ribs.Template length is generally 9 meters, and point 6 restrainings are made, and single-unit length 1.5 meters, between joint, bolt connects.The radian (arc length) of template is determined according to tunnel invert radius of curvature size, is generally 90 degree-110 degree (can suitably strengthen when radius of curvature is large, radius of curvature hour can suitably reduce).Meanwhile, be necessary for the every side of side and roof arch lining cutting and stay the lap length of establishing and being no less than 10cm.For the ease of monitored concrete condition of construction timely in work progress, the peep hole establishing some is stayed in positions different in template.
2, trailer system: can adopt the mode of traction that hoist engine, bottle gouard moved by hands, hydraulic tractor etc. are different, during actual use, need grasp according to different situations flexibly.The pulling equipment that different mode of traction is corresponding different.
3, the anti-bias system of anti-floating: for preventing concrete warehousing, vibrating and skew occur in template movement process and floats, guide rail should be installed in tunnel both sides, sliding shuttering is moved along guide rail under traction, guarantee that end arch is shaping.Guide rail generally makes of 12-16 channel-section steel, is fixed on tunnel crag, also can links together with reinforcing steel bar loading muscle by the dowel of some.Respectively arrange in the piston shoes card entry slot steel track of some in template both sides, also can inject lubrication oil in orbit, guarantee that piston shoes and track can slide smoothly.
4, concrete warehousing vibrating system: arrange aggregate bin, material-dividing groove in template, concrete is directly delivered in aggregate bin by concrete pump, by material-dividing groove to template both sides uniform distributing.Two attached vibrators are installed in template bottom, implement effectively to vibrate to concrete at the template poker vibrator that utilizes suitable for reading.Meanwhile, attached vibrator can be opened when template movement to reduce frictional resistance.
5, defect elimination curing system: at both sides, template rear portion suspension work platform, facilitates and manually to repair in time the quality defect of concrete after the demoulding on working platform; And arrange a sprinkling water and spraying fog development along the dovetail type template at rear portion, guarantee is sprinkled water to the concrete reaching initial setting strength in time, maintenance.
Processing and utilization method of the present utility model:
1, template construct: manufacture by designing requirement merogenesis in manufacturing shop, carry out an acceptance inspection after pre-assembled, qualified rear merogenesis numbering.
2, base plate cleaning: by the cleaning of project organization parting length segmentation, clean up rear examination.
3, reinforcement installation: by the firm muscle of project organization parting length segmentation colligation, and install fixed seal head template.
4, track installation: surveying setting-out mark joint bar position, install joint bar, groove steel rail is accurately weldingly fixed on joint bar, and with steel reinforcing firm welding.
5, model sheetinstallat: merogenesis is installed, by piston shoes card entry slot steel track, connects trailer system, and recovers in place after carrying out idle test, ensures that template is slided smoothly along track.
6, concrete conveying system is installed: after template is in place, at template installation concrete aggregate suitable for reading bucket, material-dividing groove, installs concrete pump, erection concrete pump pipe at correct position.
7, concrete construction: concrete adopts tank car transport, and concrete pump delivers to aggregate bin, and utilization is fixed on template aggregate bin suitable for reading and material-dividing groove symmetry is put in storage, to guarantee template not sidesway.Utilize flexible axle shock club and form vibrator to vibrate, two plug-in type shock clubs and two form vibrators are arranged in each storehouse.Concrete adopts carvel built stone, namely first vibrates at bottom intermediate blanking, then from bilateral symmetry blanking, balanced rising, the positions such as the both sides discrepancy in elevation must not be greater than blanking thickness, and built-in fitting is neighbouring, reinforcing bar is intensive adopt artificial pinch to expect, pile up to prevent aggregate.
8, sliding formwork slides: sliding formwork slides front track and will clean out, and when being all full of concrete and vibration compacting in two side templates, after observing concrete vibrating situation, will prepare to start to slide by peep hole.Initial skid requires that concrete strength is between 0.1 to 0.3mpa, initial skid distance is for being no more than 10cm, slide rear observation concrete demoulding intensity, do not collapse with concrete formation and be advisable, once 50-60cm is slided after meeting requirement of strength, then proceed concreting, template of going round and beginning again slides and hockets with concreting, reaches the object of sequential production.
9, concrete defect elimination maintenance: because bubble during end arch concreting is not easily discharged, be adsorbed in template surface, easily form pitted skin after the demoulding, maintenance platform therefore will be utilized after the demoulding in time to carry out magma reparation, require light, even, smooth.Concrete after the demoulding adopts gunnysack to cover or sprinkle water and spray maintenance.
