Surrounding steel pipe, the polyethylene film of backrush is returned in the groove of parapet 12 and is tamped with cement mortar, light is helped and does flashing
Processing.
Is paved bar-mat reinforcement with the stone of 10-15mm after bar-mat reinforcement Pu Let are complete, is laid with pea gravel concreten, is rolled warehouse and help
Light.
After pea gravel concreten is laid with two hours, the steel pipe of surrounding is taken out, the polyethylene film of backrush is returned into design position,
The upward Dou of parapet certain altitude is stretched into daughter's Wall grooves, with 1:, Xia Sew and light is helped in 2 cement mortar grouting reality.Steel bar end
It returns only daughter Wall to do the general Water treatment pressure of surrounding again and buy troweling paste mixing daughter Wall, and pushes down flashing connector, the poly- second of water outlet
Alkene film Even fittings should stretch into protection pipe Inner, Even and connect drainpipe and water outlet of the installation with drainpipe same type size inside waterproof case
Mouthful, for draining, the pipeline waterproof component of roofing is protruded, is bound securely with iron wire, strictly being sealed with coagulation prevents percolating water.
Each position Fen Ge Sew are after seven days, using Li Qing Guan Sew；Design flower pond person in roofing surface layer does not have to disconnect bar-mat reinforcement not yet
Secondary waterproof processing need to be done.
What the waterproof of this structure was realized in：Rainwater leaks out to Slow through pea gravel concreten layer 8 and rushes layer 7, will if water is few
It is all absorbed by water suction rebound layer, treats to vapor away when fine day.When rainwater is slightly more, waterproof layer 6 will be leaked out to, by waterproof layer
Longitude internal drainages mouth is discharged, if waterproof layer is damaged, do not find to leak out to superpower waterproof layer 4 will be discharged again through outer discharge outlet from
And ensure the water resistance of this roof covering water-proof structure.
Above-described embodiment is the optimal structure of waterproof effect, and the specific needs of root Ju waterproof in said structure can also
Do not set heat preservation heat insulation layer 5.
This structure is as follows through tests below situations：
Under conditions of technical know-how, 1987 by this Wu faces Fang Shui Knot structures it is tentative for live select building roof waterproof, roofing
Product 500m2, in August, 2016 after testing without any part leakage.
Under conditions of secrecy, 1989 tentative in house building roof, roofing to accumulate by the anti-water Knot structures in this room face
260m2, carry out destructive testing locally 660 kilograms/m of exceeded compression2And often there are ponding many places, surface finds cracking, there is tortoise
Pattern becomes a fine day 1-2 days, and water accumulation leaking to superpower waterproof layer is discharged by outer discharge outlet, do not find percolating water.
Water outlet in above example is：The vertical or horizontal universal discharge outlet of.According to actual conditions, should use upper
The waterproof material for stating phase homogenous quantities is fabricated to the small discharge outlet discharge outlet length of the big of different-diameter according to downcomer mounting distance
It determines, each water outlet together with welding of superpower waterproof layer and waterproof layer is respectively welded on super Strong waterproof layers and waterproof layer.Anti-
A piece drainpipe with drainpipe same model of installation is used for draining and installs the interior row of band edge in the water outlet that water material makes
The mouth of a river, the water outlet that waterproof material makes, outside install a draining protection pipe additional, protect the discharge outlet of drainpipe polyethylene film not
By ultraviolet radiation or damage, protective layer can be done with concrete or cement mortar when having ready conditions.
