Abstract
The invention discloses a waterproofing work technical process by a spay-painting method. The waterproofing work technical process comprises the steps: base layer treatment, special part treatment, waterproofing layer construction and maintenance. The cost of the base layer treatment of the technology is basically zero; compared with the cost of other waterproofing materials, the cost of the technical process is saved by about 40-50 RMB per square meters; after waterproofing layer construction, no protection layer is needed, and backfilling can be directly carried out on an outer wall of a basement; the waterproofing material is extremely high in automatic crack restoration function (the crack is smaller than or equal to 0.4mm), and shrinkage cracks of concrete can be resisted; finished protection and repairing are facilitated, and the waterproofing work technical process is suitable for concrete engineering sealing, aquatic engineering waterproofing and the like of the basements, tunnels, dams, reservoirs, swimming pools, a sewers, sewage treatment plants and other buildings above and below the ground.
Description
Technical field
The invention belongs to technical field of building construction, refer to a kind of spraying process water-proof treatment technology flow process especially.
Background technology
The GB 18445-2001 " cementitious capillary waterproofing material " that National Quality Supervision Bureau General formally implemented on March 1st, 2002, for cementitious capillary waterproofing material construction technology and construction quality accident provide enforceable theoretical standard.Water-proof mechanism: a kind of spraying process water-proof treatment technology flow process uses inorganic mixture, under the guiding of water, take water as carrier, by strong permeability, (the general permeable degree of depth reaches 150mm, maximum length of penetration reaches 300mm), transmit in concrete micropore and capillary tube, full, there is physical reaction, form water-fast complicated and confused shape crystalline solid, filling capillary channel, crystalline solid and concrete structure is made to be combined into closed waterproofing course overall, it can intercept current from any direction and other corroded by liquid, the competent upstream face of building and the waterproof of back side very like a cork.After several years, can also secondary crystallization be carried out, waterproof on one day can be accomplished completely, carefree all the life.
Summary of the invention
A kind of spraying process water-proof treatment technology flow process is: base treatment---special parts treatment---construction of waterproof layer---maintenance.
Base treatment: 1. concrete or masonry structure intensity meet design and code requirement; 2. basal plane smooth, firm, clean, without ponding, without dust, floating ash, oil stain and other pollutants; 3. formation level has abundant, open capillary system (coarse Absorbable rod moisture), so that the bonding and generation of applicable crystalline solid in inside of waterproofing materials; 4. the hole that the concrete with honeycombed spots of short texture and hollowing, connecting sewing, crack, dress pull bar and foot rest etc. stay must carry out removing and repairing in advance.
Special parts treatment: 1. uneven and crack place needs mortar levelling, there is no obvious seepage; 2. negative and positive angle should be made arc chord angle; 3. more than the crack of 0.4mm, must be processed.
Construction of waterproof layer: 1. construction is front by moistening for working face clear water; 2. professional spraying equipment is selected; 3. the first very thin slurry sprayed one deck and prepare, then spray the slurry that the second layer is thicker, the use amount of two-layer slurry is 0.8 ~ 1.0kg/ m2; 4., on masonry structure surface: first spray first floor waterproofing slurry, before slurry initial set, the slurry in brush spraying, direction is contrary with spraying.Average dose is 0.8 ~ 1.0kg/ m2.5. waterproofing layer thickness is greater than 0.8 ㎜, is generally no more than 2 ㎜.
Maintenance: 1. use atomizing method wet curing after coating initial set.Spray water general every day 3 times, for three days on end, hot day and dry weather will spray several times more.2. coating construction latter 12 hours planted agents avoid burning sun and drench with rain, the weather such as frost.3. for structure such as ponds, must ability retaining after coating construction and maintenance places 2 days.
The scope of application: be applicable to basement, tunnel, dam, reservoir, swimming pool, sewer, Wastewater Treatment Plant and other undergrounds, building, concrete work sealing, Shui nationality engineering waterproofing etc. on the ground.
beneficial effect
By strong permeability, (the general permeable degree of depth reaches 150mm in the present invention, maximum length of penetration reaches 300mm), carry out transmitting, filling in concrete micropore and capillary tube, there is physical reaction, form water-fast complicated and confused shape crystalline solid, filling capillary channel, makes crystalline solid and concrete structure be combined into closed waterproofing course overall, it can intercept current from any direction and other corroded by liquid, very like a cork the competent upstream face of building and the waterproof of back side.After several years, can also secondary crystallization be carried out, waterproof on one day can be accomplished completely, carefree all the life.This material is to basal plane without particular/special requirement, and preparation that need not be careful, need not measure, cut, strengthen and seal corner etc., also can not be pierced, tears or start, and without construction joint; Easily ensure the quality of products in closing ins place such as process negative and positive angles; Construction is simple, can reduction of erection time greatly; This waterproofing materials base treatment cost is almost nil, to reduce expenses about 40-50 yuan/m2 compared with other waterproofing materialss; Do not need topping after construction of waterproof layer, outer wall of basement can directly backfill; This waterproofing materials has the automatic repair function in very strong crack (≤0.4mm), can resist concrete shrinkage crack; Be conducive to finished product protection and maintenance.
