The utility model provides a kind of concrete water-saving moist keeping maintenance film, including folds impermeable layer, the non-woven fabrics set successively
And absorbing membrane, non-woven fabrics and the absorbing membrane surface are equipped with some water-absorption particles, the absorbing membrane covers away from non-woven fabrics side
If one layer of glue-line, the water-absorption particle on the absorbing membrane top layer penetrates the glue-line, and the water-absorption particle is membranaceous water-absorbing resin.
Preferably, the non-woven fabrics is weaved cotton cloth for water conservancy project.
Preferably, the absorbing membrane is filamentary member.
Preferably, the impermeable layer is plastic foil.
Preferably, the thickness of the glue-line is 0.1mm.
Compared with correlation technique, concrete water-saving moist keeping maintenance film provided by the utility model has the advantages that：
First, the concrete water-saving moist keeping maintenance film is provided with a glue-line on absorbing membrane, has self-adhesion function, can be well
Adsorb in concrete surface layer, do not depart from, construction is simple, and a water is poured before being only used in plastic film mulch in whole curing cycle, use this
Curing film water consumption is gunnysack, 1/ (50-100) of geotextiles, substantially reduces cost and difficulty of construction, is that one kind has obvious water saving
The environment-friendly materials for the function that lowers consumption；
2nd, water-absorption particle is precast body, is not fallen out, and can discharge moisture, the concrete water-saving to concrete well
Moisturizing and curing membrane effectively improves temperature in the shed and humidity, builds a constant environment, promotes concrete early strong, reduces fine fisssure
Line；
3rd, the concrete water-saving moist keeping maintenance film coiled material laying speed is fast, small volume, reduction cost of transportation in light weight.
Energy clean construction, lifting construction overall image, ensures construction quality；
4th, the concrete water-saving moist keeping maintenance film can be effectively accomplished curing requirements, can not only apply to highway, bridge
The maintenance of the engineering concrete such as beam, dam, airport, harbour, also can large-scale popularization use in building engineering.
Brief description of the drawings
Fig. 1 is the structural representation of concrete water-saving moist keeping maintenance film provided by the utility model；
Fig. 2 is concrete water-saving moist keeping maintenance film dimensional structure diagram provided by the utility model.
Embodiment
Describe the utility model in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that do not conflicting
In the case of, the feature in embodiment and embodiment in the utility model can be mutually combined.For sake of convenience, hereinafter such as
There are " on ", " under ", "left", "right" printed words, only represent that the upper and lower, left and right direction with accompanying drawing in itself is consistent, not to structure
Play restriction effect.
As shown in Figure 1 and Figure 2, the concrete water-saving moist keeping maintenance film includes folding impermeable layer 1, the non-woven fabrics 2 set successively
With absorbing membrane 3, non-woven fabrics 2 and absorbing membrane 3 surface is equipped with some water-absorption particles 4, and the absorbing membrane 4 is away from non-woven fabrics one
Side covers one layer of glue-line 5.The water-absorption particle 4 on the top layer of absorbing membrane 3 penetrates the glue-line 5.
The water-absorption particle 4 is membranaceous water-absorbing resin, and it forms gel particle after absorbing water, and keeps uniform moisture in film to delay
Slowly discharge.
The non-woven fabrics 2 is weaved cotton cloth for water conservancy project.The absorbing membrane 4 is made up of fiber.The impermeable layer 1 is plastic foil.
The thickness of the glue-line 5 is 0.1mm, can be boiled dumpling, that is, getting wet has glue, and viscosity is just lost after solid carbon dioxide.
Concrete water-saving moist keeping maintenance film provided by the utility model lays step：
The first step, concrete are stripped after pouring into a mould 24h, remove the debris such as laitance and the sand grains of concrete surface, and are ensured mixed
