Description
Technical field
The utility model relates to a kind of incubator, particularly a kind of support grouting incubator that is applied to special line for passenger trains.
Background technology
The construction of Line for Passenger Transportation is China's economy and society development and the modern inevitable requirement of railway construction, and the fierce impetus of its development is also had higher requirement to the speed of construction.
For guaranteeing to be open to traffic the time, box beam erection often is required to carry out winter construction to guarantee the duration, because the construction period is short, the winter period of rest is long, this requirement is particularly strong at severe cold area.And that the support grouting operation of one of important step in the operation of setting a roof beam in place is influenced by temperature is bigger, in the winter time during construction operation, unfavorable factor such as low because of temperature, that wind-force is big, the traditional measures that is incubated with the cotton-wadded quilt parcel often can not guarantee grouting quality, and getting on the grout blanket intensity has also directly influenced the progress of setting a roof beam in place slowly.
The tradition heat preserving method is: with cotton-wadded quilt (or other flexibly thermal insulation material) parcel warm-air drier the grout blanket that perfusion finishes is heated up, is incubated.Because cotton-wadded quilt is softer, can not form continuous cavity in the space of being wrapped up, hot blast can't circulate, and causes grout blanket uneven in temperature, and gain in strength everywhere differs.Warm-air drier also can can't be discharged to cause and self be crossed cause thermal damage because of hot blast.If monitoring is ineffective, will cause grout blanket to be endured cold, cause serious quality accident.Because working space is narrow and small, can only adopt warm-air drier that the grout blanket that perfusion finishes is heated up during winter construction usually again, under air cooking, it is infeasible adopting curing agent verified.Traditional way is: in the process that heats up, is incubated, carry out health with watering can at the grout blanket surface sprinkling, when the test cube in the same condition rupture strength reaches 10Mpa, stop moistening and intensification.Ftracture because of overheated as the untimely moistening grout blanket that easily makes, also can get slowly on the intensity because of lack of water causes hydration reaction insufficient.There is the irregular phenomenon of heating in conventional method, heating less than the zone, the mode of wet curing easily makes grout blanket endure cold.Raise cotton-wadded quilt inspection, when spraying water, also can be air-cooled, wind is big, causes temperature sharply to descend owing to the northeast severe cold area, grout blanket cracks.
The utility model content
The purpose of this utility model provides a kind of special line for passenger trains support grouting incubator, and in the time of solving winter construction, grout blanket did not reach hole strength and the technical problem of crackle occurred.
For achieving the above object, the utility model adopts following technical scheme:
A kind of special line for passenger trains support grouting incubator, comprise the insulation casing, described insulation casing is combined into rectangle by two " L " shape warming plates, the middle cavity that forms, " L " shape warming plate side plate wall middle position has the thermal source access port, the embedded warm-air drier of thermal source access port, warm-air drier head air outlet is towards cavity, and the afterbody air intake is in the incubator external body.
The inboard bottom and upper segment place of described insulation casing is connected with safe edge.
The inside corner place of described insulation casing is connected with corner protector.
The inboard edge of described insulation casing is connected with safe edge and corner protector.
The thickness of described insulation casing is 50mm-80mm.
The material of described insulation casing is cystosepiment, extruded sheet or benzene plate.
Compared with prior art the utlity model has following characteristics and beneficial effect: in the special support grouting winter construction of railway visitor, the maintenance method that has replaced traditional cotton-wadded quilt parcel insulation in the mode of haybox cooking, make grout blanket reach hole strength at short notice and mass defects such as crackle do not occur, satisfied the needs that the case beam sets up continuously.
It is mobile that hot air circulation is convenient in insulation when the utility model carries out support grouting winter construction maintenance, its cavity, and maintenance effect is good.Incubator wooden partition upper shed position, big I are decided as requested, are convenient to the access of multiple thermals source such as hot blast, steam.
" mouth " type incubator that the utility model adopts " L " type warming plate to be assembled into embeds warm-air drier on the warming plate wooden partition, make hot blast can circulate in case, flow, and grout blanket is heated evenly everywhere.Simultaneously, warm-air drier only head embeds warming plate, and the afterbody air intake is still stayed the outside, can continue to replenish cold wind, can not cause warm-air drier to cross cause thermal damage, has prolonged application life.
The utility model adopt the maintenance process of pouring water solve the bearing screed between curing time because of the overheated cracking problem that causes.During i.e. grouting material initial set, water filling in the grouting template immediately, the high about 1.0cm of the water surface～high 5cm of 1.5cm(grouting template, grout blanket thickness 2cm～3cm, but water filling 2cm～3cm).Because the insulation cavity temperature is generally about 40 ℃, sealing better can form warm, a moist environment, so the grout blanket gain in strength is not comparatively fast, can endure cold.The amount of water of 1cm～1.5cm can guarantee that grout blanket does not need to add water separately before rupture strength reaches 10Mpa, guaranteed that grout blanket can not ftracture because of lack of water is overheated.The quality and the progress of teletostage bridge erection construction have been guaranteed.
The utility model is applicable to when needing bearing screed compressive strength to reach 20Mpa in advance, so that when possessing bridge formation machine via hole condition, more is widely used in the winter construction of special line for passenger trains support grouting.
