Water will be built the pond wall.Should look the roofing size, proportional spacing building pond wall.The general high 180-200 millimeter of wall is near leaving the water outlet breach, high 100-120 millimeter in the gutter.What roofing was little also can be in order to avoid build division wall, and the pond wall should be built on the indoor partition wall, and its technology is: shop one deck cement mortar 3-6 millimeters thick, after closely knit processing repeatedly, press one deck brick again, and brickwork joint also will tamp cement mortar.Then, again the pond wall is all smeared one deck cement mortar 3-6 millimeters thick,, maintained after 7-10 days, do the diversion test again,, should in time adopt remedial measures and be filled up as finding seepage through closely knit processing.Roofing is little, builds one deck gravel fine aggregate concrete below 10 millimeters 20-30 millimeters thick within the walls in the pond, through closely knit processing, makes surface course, after maintenance 15-28 days, does the diversion test again, as non-leakage water, even if completion.Roofing is big, should build one deck fine aggregate concrete 25-40 millimeters thick in the pond within the walls, and wire lath is inserted in the concrete, through closely knit processing, makes surface course, maintenance 15-28 days, finishes even if carry out diversion test back.
For the building in gutter, should adopt as aforesaid multilayer cement mortar thin shell structures technology and finish, just the number of plies of cement mortar can be controlled in layer 2-4.
Other water proof building technology, as the waterproof technology in lavatory, washroom, kitchen, lavatory, at first adopt as aforesaid multilayer cement mortar thin shell structures technology and build up cement sand bed, build one deck gravel fine aggregate concrete 20-30 millimeters thick again, through closely knit processing, build the grinding stone floor at last.
The various material rates of preparation cement mortar are: cement: dry sand: water=1: 1.5: 0.3 (volume ratio).Mud content in the sand is less than 10% (volume ratio).With medium sand is good.
Below in conjunction with embodiment, water-proof roof construction technology is described in further detail: embodiment one, is not water technological operation:
Foreign material on the Prefabricated slab of roof face, floating dust are cleaned up (1); By cement: dry sand: water=1: 1.5: 0.3 (volume ratio) is mixed with cement mortar, and cement is with the portland cement of 425 common labels, medium sand, and mud content adopts tap water (2) less than 10% (volume ratio) in the sand; Tamp with cement mortar and to fill and lead up slit between plate (3); After treating 4 days, stitch parallel direction and be covered in the banded cement mortar covering layer of first floor that plate is sewed on along plate with cement mortar, layer is wide 120 millimeters, and thick 10 millimeters, the top is thicker than both sides (4) approximately; Then want trickle limit, limit to press repeatedly and smear, carry out closely knit processing (5) with ware bricklayer instrument; Cover (6) with plastic sheeting again; After treating initial set, adopt as (4-6) operating procedure as described in ditto make the second layer, the 3rd layer, until 7 layers, and the banded cement mortar covering layer that covers successively, from the second layer, every layer thickness is 5 millimeters, and width is successively wide a little, top successively thick a little (7); Cover one deck cement mortar 5 millimeters thick to adopting on remaining precast concrete plank face again, carry out closely knit processing, cover with plastic sheeting, after treating initial set, cover second layer cement mortar again, as aforementioned operation technology,, finish multilayer cement mortar thin shell structures technology (8) until the multilayer cement mortar covering layer that flushes with whole roofing; 10 days (9) of watering maintenance; Make with 40 millimeters thick of gravel fine aggregate concrete below 10 millimeters, and insert wire lath material and surface course and grinding stone layer (10) with plane, 2% slope.Embodiment two, are the water operating procedure:
