2.1.2 support materials:
2.1.2.1 neoprene bituminous mastics:
neoprene joined bitumen and solvent from the preparation of black liquid. Bond
for linoleum seams.
2.1.2.2 rubber bitumen emulsion: used for
coil binding.
2.1.2.3 rubber asphalt caulk: for special
parts, onion, movement joints and other built-in seal.
2.1.2.4 naphtha, xylene: cleaning tool for
and contaminated sites.
2.2 major appliances:
2.2.1 cleaning appliances: high-voltage
hair dryers, small shovel, broom.
2.2.2 operation tools, electric mixer, oil
brushes, drums, gas torch, or private flame spray gun, son of pressure, hand
rolled, iron roll, scissors, measuring tape, 1500mm φ 30 pipes (iron, plastic)
and dashes () line supplies.
2.3 operating conditions:
2.3.1 review drawings before construction,
preparation of waterproof construction programmes, and technical clarification.
Construction of underground waterproof works must be made by the professional
team, operator certificates.
2.3.2 tiling waterproofing design and
construction of grass-roots must be completed, and conservation is dried,
moisture content is not more than 9%; primary cracking should be smooth, solid,
not hollow, not sand.
2.3.3 the waterproof layer construction
before coating the adhesive (rapid-curing), you should clean up the surface of
the grass-roots.
2.3.4 construction materials are flammable
and should be ready for the appropriate fire-fighting equipment.
3 operational processes
3.1 process:
Base coat of grass-roots cleanup → → → additional paving
layer of hot-melt processing agent to pave and stick coil hot melt edge banding
→ →
Protective layer
3.2 basic cleanup: clean up the
construction of its grass-roots acceptance before.
Brushing primary treatment Agent 3.3:
primary surface with brush diluted with gasoline in a neoprene bituminous
binders, brushing should be uniform, not through.
3.4 additional paving layer: Add a layer of
onion, and corner parts coil. According to the specification and design
requirements will roll into the appropriate shape for paving.
3.5 Pu posted volume material: will
modified sex asphalt waterproof volume material by Pu posted length for crop
and volume good alternate, operation Shi will has volume good of volume
material, with φ 30 of tube wear into volume heart, volume material end head
than align began Pu of beginning, lit gasoline blowtorch or dedicated flame
gun, heating grass-roots and volume material handover at, gun from heating
surface keep 300mm around of distance, roundtrip spray roast, and observation
Dang volume material of asphalt just melting Shi, hand-held tube heart ends
forward slowly scroll laying, requirements forced uniform, and not woqi, laying
pressure side width should master good Full lap width of 80mm paste method,
bonded lap width of 100mm.
3.6 hot melt edge banding: heating membrane
seam using spray gun, pressure-sensitive to edge out of the asphalt cement.
Coil pitch for your head at the end of caulk-fixed filling.
3.7 protection layer construction:
flat-panel mortars or fine-stone concrete cover; finished facade waterproof
layer construction, should be diluted after sub ballast cement mortar layer.
4 quality criteria
4.1 project
4.1.1 high polymer modified bitumen
waterproofing membrane and adhesive specifications, performance, mixing ratio
design and related standards must be used, should have a qualified factory
certificate.
4.1.2 detail of special parts of the coiled
material waterproof layer, must comply with the design requirements and
specification for construction and acceptance of rules.
4.1.3 the waterproof layer is damaged and
leakage is strictly prohibited.
4.2 Basic project:
4.2.1 base should be flat, without
hollowing, sand, Yin and Yang Kok should have a rounded or obtuse angle.
4.2.2 coat of modified asphalt adhesive
should be uniform, there shall be no leakage phenomenon such as brushes,
through and pitting.
4.2.3 additional layer waterproofing laid
the width shall conform to the specifications; tiered lap width of joints
should be consistent with the norms, your head should be embedded firmly.
4.2.4 roll bonding should be solid, hollow,
injury-free, slip up, foaming, folds and other defects.
5 finished product protection
5.1 underground waterproofing layer of
embedded pipe in construction shall not touch damaged and clogged debris.
5.2 volume material waterproof layer paving
is complete, timely protection, prevention of waterproof layer construction
touched loss; external waterproof layer construction finished, design should be
built retaining walls.
5.3 volume material waterproof layer
construction of plane, shall not be placed on the waterproof layer as
construction materials and transport lanes.
6 quality problems to be noticed
6.1 volume material take received bad:
joint take received form and long side, and short side of take received width
partial small, joint at of bond not dense, received Cha damaged, and empty
drum; construction operation in the should by program play standard line, makes
and volume material specifications match, operation in the align line Pu
posted, makes volume material received long side not is less than 100mm, short
side not is less than 150mm.
6.2 empty drums to pave and stick coil
primary wet, not smooth, clean, basic woqi with coil and air drum when laying
the exhaust is not complete, Wo air coil can be the empty drum construction
base should be fully dry, roll laying should be uniform compaction.
6.3 at the root of poor waterproofing
paste: cleanup does not clean, cutting coils and root shape inconsistent paste
caused by false negative pressure side; when cleaning thoroughly clean,
attention operations, roll compaction, without mouth, Homburg, wrinkles and so
on.
6.4 leakage: corner, onion, deformation
joints difficult operation and leakage. Construction of additional actions that
should be carefully; protect Cha roll, take swift meets the width requirements,
ensuring the quality of special parts.
7 quality records
This standard shall meet the following
quality records:
7.1 waterproofing product certification,
field sampling of qualified second interview information.
7.2 factory certification, use of cement
materials Proportioning material.
7.3 hidden project check and acceptance and
quality inspection and evaluation of information.
