The constructional method of cement-base infiltration crystallization patching materials:
Step 1, water-impervious surface construction: basal plane is processed, and basal plane must be fully moistening to saturated without ponding, and require firm, totally and smooth, levelling is not leaked with concrete or water in uneven place;
After basal plane levelling, be coated with successively the first layer, the second layer, the 3rd layer (after being painted with the second layer, without infiltration, not doing the 3rd layer); Proportion scale, powder and water are 1:0.25～0.35; Every layer of consumption is 1.3kg/ ㎡, and thickness is done 2 layers for 1.5mm, does 3 layers for 2.2mm; Batching is that 1:0.25～0.35 stirs within 2 minutes, to become evenly by powder and water, does not contain the puttylike nian of fecula or granule; Apply the first layer, treat that coating sclerosis hand does not stay fingerprint, squirted, can not ponding; Carry out again second layer coating; During material loading, firmly repeatedly scraping back and forth to smear makes coating closely knit and note overlap joint;
Step 2, infiltration surface construction: basal plane is processed, and basal plane must be firm, clean, smooth fully moistening to saturated without ponding, and levelling is not leaked with concrete or water in uneven place; The serious priming hole of should getting that seeps water reduces pressure and percolating water is concentrated and drawn;
Distribution: infiltration surface construction selects rapid-hardening water not leak; By material, by powder and water, be that 1:0.25～0.35 stirs within 2 minutes, to become uniformly not containing fecula granule puttylike nian;
Coated materials: apply and do altogether two to three layers; If basal plane infiltration is serious, first in bottom, play priming hole step-down, then construction from top to bottom; Specific practice: dry basal plane upper the first layered material rapidly with dry cloth, after coating sclerosis, hand does not stay fingerprint, is squirted, and can not have ponding, at upper the second layered material, if part still has infiltration, then adds one deck, until do not leak the construction of band water; Last shutoff priming hole; During material loading, firmly and back and forth smear several times more, make coating closely knit, and note overlap joint; Every layer of materials amount is 1～1.5kg/ ㎡, and total materials amount is 2～3kg/ ㎡;
Step 3, scupper construction: first to processing base level, with chisel or reciprocating drill, scupper has been got to the above degree of depth of 5cm, in bore, mouth is greater than collar extension, is shown in new stubble, and rinses well;
Sequence of construction: seal after first leak stopping:
Distribution: scupper leak stopping selects rapid-hardening water not leak; Leak stopping material is 1:0.25 by powder and water, and kneading becomes material group repeatedly; Sealing compound is 1:0.3～0.35 by powder and water, stirs and within 2 minutes, becomes even puttylike nian;
Coated materials: according to scupper shape, leak stopping material is pinched into the material group that is slightly less than scupper size, be placed into after having pinched hard sense with hand and fill in scupper, with wooden stick extruding, gently pound and make it compacted to surrounding, moment leak-stopping, the sealing compound on trowel for 10cm place around in scupper outside then; Leak stopping order is wanted the following scupper of first leak stopping mouth of a river diameter 5mm, the above scupper of rear leak stopping mouth of a river diameter 5mm.
The invention has the beneficial effects as follows: this invention antiosmotic pressure is high, viscosifying power strong, water-tolerant, anti-aging, nontoxic, tasteless, pollution-free, can be with water construction, easy construction.
