Operation process
3.1 Process:
Grass-roots cleaning → brushing the primary treatment agent → paving additional layer → hot-melt paving film → hot-melt sealing edge → do protective layer
3.2 grassroots clean-up: pre-construction acceptance of qualified grassroots clean.
3.3 brushing the primary treatment agent: in the grass-roots surface brush with a gasoline diluted with chloroprene rubber asphalt adhesive, brushing should be uniform, not through the end.
3.4 paving additional layer: root, yin and yang part of the extra layer of a layer of membrane. According to the specifications and design requirements of the coil will be cut into the corresponding shape of the paving.
3.5 paving sheet: the modified asphalt waterproofing membrane according to the length of the paving cut and roll the spare, the operation will be rolled before the coil, with φ30 tube into the heart, the coil ends than Qi start The starting point of the shop, the ignition of gasoline torch or special flame spray gun, heating the grass and the junction of the material, the gun from the heating surface to maintain the distance of about 300mm, from the spray barbecue to observe when the coil just melted, Move forward slowly rolling, requiring uniform force, not Wo Wo, laying the width of the pressure should be mastered, full of law lap width of 80mm, strip of lap overlap width of 100mm.
3.6 hot-melt edge: coil lap joints with a spray gun, pressed to the edge of the extrusion asphalt sticky. The end of the coil is filled with asphalt caulking paste.
3.7 protective layer construction: the plane to do cement mortar or fine stone concrete protective layer; facade waterproof layer construction finished, should be timely spilled after the stone ballast mortar protection layer.
Quality Standard
4.1 Guaranteed items

4.1.2 membrane waterproof layer of special parts of the fine practice, must meet the design requirements and construction and acceptance of the provisions.
4.1.3 waterproof layer is strictly prohibited damage and leakage phenomenon.
4.2 Basic items:
4.2.1 grass-roots should be flat, no hollowing, from the sand, yin and yang angle should be round or obtuse angle.
4.2.2 modified asphalt adhesive brushing should be uniform, no leakage brush, through the bottom and pitting and so on.
4.2.3 The width of the additional layer of the waterproofing shop shall conform to the specification requirements; the width of the laminated joint lap shall conform to the provisions of the specification and the head should be embedded firmly.
4.2.4 membrane bonding should be solid, no hollowing, damage, sliding Alice, blistering, wrinkles and other defects.
Product protection
5.1 Underground membrane waterproof layer of the site of the pipeline, in the construction shall not be damaged and blocked debris.
5.2 membrane waterproof layer after the completion of paving, should do a good job in time to protect the layer, to prevent damage to the structure of the construction of waterproof layer; outside the waterproof layer after construction, should be designed to build a good wall.
5.3 Coiled surface waterproof layer construction, shall not be placed on the waterproof layer of material and construction as a transport lane.
Should pay attention to the quality of the problem
6.1 Lap joint bad: joint lap form and the long side, short side of the lap width is too small, the joints of the bonding is not dense, then Cha damage, hollowing; construction operation should be the standard line And the coil specifications in line, the operation of the line shop paste, so that the long side of the coil is not less than 100mm, short side is not less than 150mm.
6.2 hollow drums: paving the grass layer of the wet, uneven, unclean, resulting in grass-roots and membrane between the nest gas, hollowing; laying exhaust is not complete, nest the air, but also between the coiled space between the drum; Construction should be fully dry base, the roll should be evenly compacted.
6.3 pipe root at the waterproof layer paste bad: clean up unclean, cut the coiled material and the root shape does not match, bad edge caused by poor paste; construction clean should be thoroughly clean, pay attention to operation, the coil compaction, Alice, wrinkles and other phenomena.
6.4 Leakage: corner, root, deformation joints are not easy to operate and leakage. Construction of the additional layer should be carefully operated; to protect the good Zha coil, lap should meet the width requirements, to ensure the quality of special parts.
Quality Records
The process standards should have the following quality records:
7.1 waterproofing membrane should have product certification, site sampling re-test qualified information.
7.2 cementing materials should be factory certificate, the use of matching data.
7.3 hidden engineering inspection and acceptance of materials and quality inspection and evaluation information.
