Overlap joint: using overlap joint up and down, lap width 70mm, tolerance is -10 ㎜.Same layer coiled material, short side are taken
Wrong is opened not less than 500mm.
Overlapping part must clean, completely, the pollutants such as anhydrous or mortar, can first be cleared up coiled material lapping position with rag
Completely, then isolation film is removed and is overlapped.
Waterproof roll answers temporary sealing (can be close with adhesive tape or thickening cement slurry in paving on wall at coiled material closing in
Envelope), to prevent wall from receiving, moisture content at head is too fast to be scattered and disappeared.
Outer anti-outer patch method paving coiled material, when paving, should first pave face, spread facade afterwards.
Concrete structure is completed, and when paving facade coiled material, connects on the coiled material of raft position layer coiled material under layer coiled material lid.
G. side wall and top plate second waterproof construction (full bonding)
After first of waterproof coiled material construction, then second waterproof roll paving is carried out, second waterproof roll uses
Single side wet-laying polymer membranes, coiled material lapping width is the same as first of coiled material.Mistake is answered when the long edge lap of upper layer and lower layer coiled material
It opens, and no less than breadth 1/3, upper layer and lower layer short side should also be staggered not less than 500mm.
Second waterproof coiled material construction should be taken off under first of waterproof roll upper surface isolation film and second waterproof roll
Surface isolation film, by second installation of membrane on first of coiled material, after the coiled material exhaust of large area, being compacted with pressure roller, then
Overlapping part is rolled, is firmly rolled forward, outward, air, firm pasting is discharged.Overlap joint control line should be directed at when overlap joint
It carries out, it is ensured that the lap joint quality of coiled material.When paving large area coiled material, the isolation film of coil back surface overlapping part not taken off
Fall, in order to avoid pollution adhesive layer or accidentally viscous.
H. side wall waterproof protective layer: MU10 brick wall is built using M7.5 mortar, wall thickness is 120mm or 240mm.
I. waterproof roofing protective layer: using strength grade >=C20 pea gravel concreten protective layer.
For the utility model in construction, bottom plate is after-pouring concrete, therefore bottom plate uses and overlays polymer membranes,
The coiled material directly pours structural concrete mixture bonding with after, is formed whole.When differential settlement occurs for ground, such coiled material
Differential settlement can be effectively prevent to cause anti-water destruct, waterproof effect is unaffected.Side wall top plate be structure construction after again
Construction waterproof coiled material, therefore wet-laying polymer membranes is used, the waterproof roll flexibility is good, viscous using cement slurry and base
Knot, waterproof roll can be bonded with close structure, improve waterproof construction quality.
