Description
Technical field
The totally-enclosed spray drip irrigation of Concrete Lining of Canals plate of the present invention curing means belongs to the water conservancy project field.
Background technology
Xeothermic windy, evaporation capacity is multiple times than the northern serious water shortage Gobi Desert Terrain area of amount of precipitation, long distance water transfer has that scale is large, circuit is long, water source point far and less, large, the slope maintenance of channel maintenance area can't water characteristics, the maintenance quality of Concrete Lining of Canals plate is determining the win or lose of water diversion project.
Following mode is mainly taked in the concrete maintenance of present domestic large channel:
2. curing film: two kinds of minute geomembrane or composite geo-membrane, water-saving moist keeping maintenance films.
Geomembrane or composite geo-membrane all are antiseepage functions of utilizing geomembrane, with concrete surface and air insulated with water-preserving curing.This maintenance method still needs regularly concrete surface watering moisturizing under the film, but to being laid on the maintenance geomembrane on thinner thickness, concrete canal lining plate surface that area is larger, the film end need to be used for holding one's breath during each watering and the windproof gland weight that blows afloat is removed and film is started, sprinkling water presses after complete again, has not only bothered the labour intensity but also large of taking a lot of work.The strong point of this mode is that the large geomembrane of used composite geo-membrane or thickness is reusable, and water retention property is better than straw screen or mat, felt rug.
Water-saving moist keeping maintenance film is that macromolecule water absorbent material take novel controlled 200 times of moisture that can absorb own wt is as core, take plastic sheeting as carrier, only need between curing time to water water one time when concrete surface is laid water-saving moist keeping maintenance film, concrete surface can remain moistening between curing time.But because material self thin thickness, very easily damaged and swept and ineffective by wind under xeothermic windy environment, this film can only disposablely use.
In sum, these three kinds of maintenance patterns all are difficult to guarantee the maintenance quality of Concrete Lining of Canals plate.
Look into newly through retrieval, " Henan water conservancy and the south water to north " (4) periodical in 2011 has been sent out the paper " project of South-to-North water diversion Concrete Lining of Canals maintenance process pre-test " of Henan Province's water conservancy the second Li Liang of Engineering Bureau fine jade, Hu Xiang, it adopts 3 kinds of methods to carry out maintenance, be respectively: 1. natural curing method: namely cover geotextiles, the maintenance of then sprinkling water at concrete surface; 2. film covering curing method: namely after concrete surface spills one deck water, cover moisturizing with curing membrane immediately; 3. gunning concrete curing agent method of curing: namely carry out moisture-keeping maintaining at concrete surface spraying one deck curing agent.
Above-mentioned natural curing method is similar to felt rug, straw screen or mat tradition method of curing.Film covering curing method is same as the water-saving moist keeping maintenance film method of curing.Gunning concrete curing agent method of curing is same as the curing agent method of curing.
" planning for water resources development and design " (3) periodical in 2009 has been sent out the paper " application of drip irrigation zone in the maintenance of Bachu general main canal concrete slab " of the Kashi Area of Xingjiang Autonomous Region water conservancy and hydropower Han Xiu of surveying and designing institute, Liu Guoqiang, its method is: establish two of special water boxes 1., water tank can adopt waste and old oil truck repacking, and water tank places respectively on the canal dike of the left and right sides; 2. water tank upper is established one of inlet valve, directly connects water inlet pipe, or establishes a square aperture of 30cm at the top, conveniently adds water; 3. the water tank bottom sets out one of penstock, directly links to each other with plastic flexible pipe, beats Three-way pipe with snap fastener at plastic flexible pipe and links to each other with the drip irrigation zone, and according to temperature situation choose reasonable drip irrigation zone quantity, vertically lay along the canal dike drip irrigation zone; 4. after the drip irrigation zone installs, open water tank below flowing water Valve, the concrete curing water goes to the canal underflow with the drip irrigation zone.
The drip irrigation zone method of curing is the quantity of selecting the drip irrigation zone according to climatic condition, and vertically lay along channel the drip irrigation zone, thereby the maintenance water reaches the maintenance purpose at the bottom of flowing to canal along the drip irrigation zone.Its advantage is: the maintenance water consumption of more manually sprinkling water will lack, and water supply process is easy, has reduced labour intensity, can be evenly distributed on concrete surface when the maintenance of light section channel is supplied water, and maintenance effect is good.Shortcoming is: (1) does not form the long-term wet environment of supporting.Concrete surface is in the moist curing environment during cistern water supply, and the rear concrete surface of cutting off the water is in dry state very soon, without water curing.If curing time is wanted the concrete surface moisturizing, supply water and just can not be interrupted, so that water supply volume and quality monitoring workload are all larger.(2) be not suitable for the maintenance of large hydraulic engineering canal cross section.Owing to be furnished with longitudinal and transverse cutting seam on the liner plate, after maintenance was supplied water and run off along the cutting seam, the bottom concrete slab seldom or can not get the maintenance water; If such as artificial cast in place concrete plate, relatively poor because of planeness, the maintenance water is difficult to be evenly distributed on the concrete slab surface.(3) because cistern water supply will have certain head that pressure is just arranged, plastic flexible pipe adds the drip irrigation zone and supplies water apart from limited, and the water tank input amount is large.
