Description
Technical field
The utility model is related to a kind of formwork cloths for high-speed railway rapid-patching motar and concrete, belong to high-speed iron
Road repair apparatus technical field.
Background technology
Since reform and opening-up, with the rapid development of national economy, railway construction in China especially high speed railway construction obtains
Fast development is arrived, the transport power of railway traffic is greatly improved, and huge change is brought to the travel modal of people
Become.Since ballastless track of high-speed railway inevitably will appear damage under long-term operation and extraneous Complex Natural Environment effect
And aging, the train run at high speed can be more serious to the destruction of non-fragment orbit, if repairing not in time, can influence train operation and relax
Adaptive even jeopardizes traffic safety.China's non-fragment orbit circuit is long, trans-regional big, these objective circumstances determine that repair skylight is set
Short-time characteristic must be had by setting, domestic at present to use 4 hours vertical " skylight " substantially.In so short skylight point, maintenance work
Process on line should be reduced to the greatest extent, improve maintenance efficiency as far as possible under the premise of ensureing repair quality.
For coming to nothing, the general repair technology that arrisdefect, the non-fragment orbits such as breakage destroy be：Preparation of construction --- cut damage
--- --- formwork --- pours mending mortar or mending concrete --- form removal --- to beat cleaning sundries for mortar or concrete
Mill --- scene cleaning.Wherein formwork needs brushing releasing agent at the scene, and polishing is primarily to after processing and modification form removal
Side layer.Since common Steel-wood forming board degree of closure is higher, mortar or concrete cannot be helped to exclude extra moisture and gas,
The defects of washmarking, honeycomb, pitted skin and trachoma are readily formed after form removal, polishing become essential in high ferro repair technology
A joint, and work of polishing is quite time-consuming, it is difficult to reach the original intention for improving maintenance efficiency.
Invention content
In order to solve the deficiencies in the prior art, the utility model provide it is a kind of for high-speed railway rapid-patching motar and
The formwork cloth of concrete, uses between mending mortar or mending concrete and template, has the maintenance to mortar and concrete
Mix water and air extra in mortar or concrete surface layer can be discharged in function, can substantially eliminate mortar or concrete surface
The surface defects such as washmarking, honeycomb, pitted skin, trachoma, surface receive light grinding process without carrying out, reduce high ferro reparation construction technique,
It is easy to use, improve repairing efficiency.
The utility model is technical solution used by solving its technical problem：It provides a kind of fast for high-speed railway
The formwork cloth of fast mending mortar and concrete, including formwork cloth ontology, the formwork cloth ontology include maintenance successively from top to bottom
The upper surface of gel layer, filter layer and padding layer, the padding layer is hair side, and the lower surface of padding layer is coated with non-drying glue layer,
Ground paper layer fits in the lower surface of padding layer by non-drying glue layer, and the aperture of the filter hole on the filter layer is 20~35 μm.
The thickness of the padding layer is 1~2.5 μm.
The utility model is based on advantageous effect possessed by its technical solution and is：
(1) a kind of formwork cloth for high-speed railway rapid-patching motar and concrete provided by the utility model, the 1st layer
To conserve gel layer, it is sprayed at the film gel that the 2nd layer of filtering layer surface is formed for a kind of macromolecule new formulation, it is non-to use shape
State is desiccant gel state, and mortar or concrete mortar are met when use, when moisture evaporation to a certain extent, one layer can be quickly formed
Colourless, fluid-tight film can prevent the moisture evaporation in concrete or mortar, reduce concrete shrinkage and cracking；2nd layer is
Filter layer, it is bright and clean, fine and close, there is small pore, cement granules can be prevented through water and air by being contacted with mortar or concrete
Pass through；The performance that 3rd layer of padding layer has water conservation ventilative, water holding capacity are more than 0.25L/m2, and drainability is more than 0.4L/m2,
Padding layer act as retaining moisture appropriate, and extra moisture oozes out, and gas appears, and mortar or concrete surface is made to locate always
In moist environment；
(2) a kind of formwork cloth for high-speed railway rapid-patching motar and concrete provided by the utility model is being repaired
It is used between mortar or mending concrete and template, stop-off slurry or the mending concrete moisture extra when pouring, bubble pass through
The filter layer of formwork cloth enters padding layer, and bubble escapes in padding layer, and the part in moisture accumulates in padding layer, extra
Moisture oozed out along formwork cloth outer, which can effectively reduce the water-cement ratio and defect of mortar or concrete surface layer
Rate, and can be while extra mixing water is discharged to provide early stage moisture-keeping maintaining before mortar or concrete form removal, the material
Beautify mortar or concrete surface, improve the quality and durability of structure, body structure surface is received light grinding process without carrying out, reduced
High ferro reparation construction technique improves repairing efficiency；
(3) provided by the utility model a kind of included not for the formwork cloth of high-speed railway rapid-patching motar and concrete
Drying adhesive layer, when use, directly tear base stock and stick at template surface, change formwork cloth traditional handicraft Nian Jie with template ---
Application angle glue sticking agent, this direct technique for sticking is easy to use, does not cause bonding agent waste, time and labour saving, reduces material wave
Expense does not generate the trouble that the fragmentary accessory of increase is brought, may be omitted with line cope plate brushing mold release technologies, further saves work
The skill time improves efficiency.
