Abstract
The invention relates to curing which is applicable to concrete structural objects such as a road bridge girder and a culvert, a cement concrete structure and a structural basic layer, in particular to a construction method for a water-saving moisture-preserving curing film of a concrete structure. The method comprises the following steps that after cast-in-place concrete is demoulded, dirty objects on a to-be-cured concrete vertical face are thoroughly removed firstly, and a strip of double-faced adhesive tape is stuck on the vertical face by every 1.5 m-2 m from top to bottom; according to the construction method of the water-saving moisture-preserving curing film of the concrete structure, a plastic film serves as a carrier, watering is conducted for one time during paving, after water absorption, the liquid water is changed into solid water, 600 g-1000 g water can be stored in the film of per square meter, and then a small reservoir is formed; then, in the degradation process of macromolecule materials, the water is delivered to the curing face through thin glass tubes, meanwhile steamed water in concrete or in the basic layer hydration process is constantly absorbed and then acts on the surface of a curing object; and circulating and repeating are conducted in such a way, and the efficient moisture-preserving effect can be achieved without watering within a curing period.
Description
Technical field
The present invention relates to be applied to the concrete structures such as highway bridge, culvert, cement concrete constructions and structured base layer
Maintenance, more particularly to a kind of construction method of xoncrete structure water-saving moist keeping maintenance film.
Background technology
In xoncrete structure irrigation process, mostly moisturizing is carried out using work cloth gunnysack, geotextiles, gunnysack need to be by not stopping
Water and can be only achieved the effect of moisturizing, this should ensure there are enough waterwheels, ensure that Shi Shuizhe has enough sense of responsibility again,
And this human factor be difficult control in optimum state, it is impossible to ensure-individual preserving period in geotextiles, gunnysack be always to maintain height
Wet condition, does not have the effect of lasting moisturizing, and in summer high-temperature season, the method for this health of watering is more readily formed health layer
Wet, suddenly cold and hot when doing during face, causes the generation of microcrack, and is also unfavorable factor to slight formation.
The content of the invention
The present invention proposes the construction method of xoncrete structure water-saving moist keeping maintenance film.
A kind of construction method of xoncrete structure water-saving moist keeping maintenance film of the present invention, comprises the following steps：
（1）The booty on the concrete vertical face for needing health should be removed first after the cast-in-place concrete demoulding it is clean, every 1.5 meters-
2 meters are sticked from top to bottom a double faced adhesive tape, and at -2 meters of 1 between two double faced adhesive tapes meter, 5 centimeters of fritters of uniform perpendicular patch are two-sided
Glue, so that the edge of film is viscous steady in facade；23 centimeters of long double faced adhesive tapes are uniformly pasted at isolated edge 0.5 or 1 meter, so as to
Center membrane is viscous steady in facade.The barrier paper on double faced adhesive tape should not now be torn；
（2）The concrete vertical face for needing health is uniformly irrigated with clear water, is most much poured 5-9 time, mix after curing film with ensureing to be sticked
Solidifying soil has in a short time more steam water to absorb by curing film；
（3）After watering, the double faced adhesive tape barrier paper of be attached to concrete vertical face is torn；
（4）Pad pasting should be followed and got on, get off, horizontal paving, curing film volume is erect and the one side that curing film has hole is close to into coagulation
Native health facade：Transversal moving forward is moved, and the upper edge of curing film should be close to the centre of 5 centimeters of double faced adhesive tapes：Curing film is allowed to be close to
On double faced adhesive tape；
（5）After the completion of curing film paving, just water into film along facade from the top down, make film inner macromolecule absorbing material abundant
Water suction, curing film just can tightly be adsorbed in health facade after water suction, and humidity can reach 95% in two to three days caudacorias, play moisturizing
What is be incubated drags bang effect；In Arid Area, 9-15 can be poured in the 2nd road flow process all over water；
（6）After the completion of watering, the broken end for taking egress edge and film between film and film is sealed using 5 centimeters of wide adhesive tapes
Extremely.
Preferably, a kind of construction method of xoncrete structure water-saving moist keeping maintenance film, it is characterised in that the concrete road
The step of face method for moisturizing, is as follows：
（1）After concrete road surface paves 30 to 40 minutes, road surface is touched with hand, just should cover plastics when on hand without open fire big
Film；
（2）After concrete road surface cuts expansion joint, the residues such as the sawdust on expansion joint and panel should be cleaned up；
（3）Product external packaging is opened, the inner bag end socket at product two is removed, curing film is arranged in road surface echelon, two is adjacent
Film lap width is no less than 5 centimeters；
（4）With 10 meters of distance as curing film-and the individual laying stage, the following operation of repetition：First sprinkle water, until road surface free water is thick
Spend for 3-4mm, by the curing film for arranging in road surface rolls forward, make film inner macromolecule absorbing material fully absorb water, to thickness
For 5～Omm；
（5）In whole process of deployment, two adjacent film lap widths will be kept all the time on 5 centimeters；
（6）There is overlap joint glue on the both sides of film, are capable of achieving the stickup of film and film overlap joint, reuse transparent adhesive tape that width is 5 centimeters by film
Lap-joint pastes；
（7）A small amount of cement block or aggregate are pressed again：The mould reality paved at center isolation strip and curb；
（8）Film will cover the both sides sidewall edge of concrete plate, and mono- 20 centimeters of reserved 1O is used with pressure sandstone.
The present invention pours a water with plastic foil as carrier in laying, after water suction, aqueous water is changed into solid water, often puts down
The moisture content of 600 grams～1 000 grams of the film energy retaining of square rice, forms a little reservoir, thereafter in the degradation process of macromolecular material
In, health-preserving noodle is delivered to moisture content by capillary, while and the continuous evaporation water drawn in mixed doubtful native or basic unit's hydration process,
Remake for conserving thing surface, so circulation repeatedly, just can be in-individual preserving period without the efficient moisture-retention that also can reach that rewaters
Effect, under normal circumstances, humidity can reach 95% in first three day in film, can reach 90% within seven days.Simultaneously because the heat of water
Capacitive is very big, so curing film can play good insulation effect after fully water suction to concrete curing face.
