Description
Technical field
The present invention relates to railroad track, especially relate to a kind of track board concrete method for filling.
Background technology
Along with Chinese economic development, railway traffic as the urban traffic system has become the important tie that big and medium-sized cities connect, the application of ballastless track and tunnel, roadbed are different, the TERM DEFORMATION of ballastless track under elastic deformation under the mobile load effect and dead load effect all can directly have influence on stressed, ride comfort and the traffic safety and the comfortableness of track structure, thereby the shop of ballastless track just becomes the key of ballastless track prestressed concrete design.
The vibration of Rail Transit System is mainly produced by the following aspects: when train moves with certain speed, the gravity of rail is loaded the impact of generation; When train moves on rails, wheel and rail structural vibrations that wheel-rail interaction produces; When cartwheel roll is crossed rail joint, wheel and rail structural vibrations that wheel-rail interaction produces; The irregularity of track and the damage of wheel also are the vibration sources of system vibration.Thereby track planarization and density are required is that track normally moves, and the assurance that reduces to vibrate for this reason, has been developed a kind of track plate conerete pouring method specially.
Summary of the invention
Based on above-mentioned need of practice, it is good to the purpose of this invention is to provide a kind of track plate density, planarization of making, and the high track plate conerete pouring method of intensity.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of track plate conerete pouring method comprises the steps:
The first step, check before the perfusion:
Steel mesh reinforcement in track template die type and the model is laid correctly; All built-in fittings of track plate are laid correctly, and must be closely connected with the model surface of its permanent position, do not allow the slit and exist; Evenly be furnished with the bottom vibrator in the model bottom, on the longitudinal rail of model upper edge, lay plate vibrator;
In second step, infusion funnel is arranged on the model top, and the concrete that meets design requirement is housed in the infusion funnel;
In the 3rd step, the control operating ambient temperature is in 10～35 ℃ of scopes;
The 4th step, perfusion and vibration:
Perfusion: the concrete spouting in the infusion funnel of will packing into is gone in the model, and the perfusion of monoblock track plate should be finished before concrete initial set;
Vibration: in perfusion, adopt the end to shake and assist the vibratory process of the combination of shaking with top, promptly
With the perfusion of model inner concrete, open the vibrator of model bottom successively; When the end, shake the power deficiency, in concrete, insert vibrating head from top and vibrate, each vibrating head should be inserted to the model bottom, and vibrating head does not hit all built-in fittings and the reinforcing bar in the movable model during vibration; Being vibrated to concrete surface no longer emits bubble, surperficial bleeding and nothing significantly to sink to being as the criterion;
The 5th step made plate vibrator along model upper edge longitudinal rail direction vibration, to guarantee the concrete compaction of corner and built-in fitting periphery in the model; And concrete surface caught up with the real and leveling of densification, cause surperficial bleeding and no stone and expose and be as the criterion;
In the 6th step, the floating concrete surface in vibration back is noted filling out the limit fillet, and satisfies track plate surface finish and be no more than 5mm/m.
Described each vibrating head inserts once every about 0.15～0.25 meter, vibrates 26～35 seconds at every turn.
The perfusion of monoblock track plate should once be finished.
Behind summer floating concrete surface, in time concrete surface is covered, avoid making the quick dehydration of concrete to cause thousand to split.
The present invention checks before perfusion, be because: the making of track plate is to build to finish in model, at first places the steel mesh reinforcement in track template die type and the model, guarantees the physical dimension and the intensity of track plate; All built-in fittings of track plate are laid correctly, and must be closely connected with the model surface of its permanent position, do not allow the slit and exist, in order to guarantee the surfacing of track plate; Evenly be furnished with the bottom vibrator in model bottom, on the longitudinal rail of model upper edge, lay plate vibrator, be for concrete spouting closely knit and smooth.
Infusion funnel is arranged on the appropriate location of model top among the present invention, and general infusion funnel is about 1m apart from the height of model; The concrete that mixes and stirs by designing requirement should be cleaned out infusion funnel is inside and outside before the infusion funnel of packing into, and the moistening infusion funnel inwall of spraying water; In infusion funnel is fed into model the time, the staff notes controlling the swing of infusion funnel, and is even to guarantee blanking with concrete, and guarantees safety, and the amount of blanking is simultaneously wanted appropriateness, flushes the model end face and is as the criterion to vibrate the back concrete.
The present invention controls operating ambient temperature in 10～35 ℃ of scopes, is in order to guarantee concrete various performance, and the quality of track plate and technical indicator.
The perfusion of monoblock track plate of the present invention should be finished before concrete initial set, and as far as possible once perfusion finish, be to prevent to pour into the designing requirement of arriving of the inhomogeneous quality that causes the track plate and technical indicator.The present invention adopts the end to shake in perfusion and assists the vibratory process of the combination of shaking with top, is in order to get rid of bubble in the concrete, to make that simultaneously concrete spouting is closely knit.
The function of middle plateform vibrator of the present invention is concrete to be carried out face shake, and concrete grout is shaken, and guarantees that concrete surface is smooth, and planeness reaches requirement, and the error range of controlling the track plate height simultaneously is within 0～3mm.
Beneficial effect of the present invention: the track plate that pours into out by the present invention not only planarization, density is good, and the intensity height, high load capacity carrying continuously; Utilize the present invention to pour into the track plate, not only production efficiency height, and yield rate height.
The specific embodiment
Preferred embodiment is as follows:
A kind of track plate conerete pouring method, carry out as follows:
