A project overview ****** brief, the project is a common type of expansion joints waterproof sealant pouring process, due to the waterproof aging, shrinkage, cracking, foundation settlement and other factors led to inconsistencies coefficient leakage, seriously affect the market The normal business activities. Second, the causes of leakage after we notified immediately send technical staff for the actual situation of water leakage through the site for the project, the geological conditions, construction, construction, water treatment and other projects for a more comprehensive understanding of View, Locate leak mainly due to: 1, basic causes: the foundation process does not take full account of that sedimentation coefficient inconsistency, caused by the expansion joints on both sides appear while high, while low. 2, the design reason: waterproof design is too simple joints, causing reach telescoping requirements. 3, sealing materials used: sealing material formerly common type sealant, anti-aging, scalable performance is low, causing the waterproof layer aging and cracking. Third, engineering leakage control programs under the project functional requirements, structural features, we follow the "waterproof engineering technical specifications" required to take "multi-channel fortification", "composite waterproof", "node seal" and other measures for the project, Selected varieties of waterproof material, to determine the structure and node approach, and propose appropriate technical measures program. Fourth, waterproof material selection: 1,50 × 50mm water expansion of the seal (Executive GB / T18173.3-2002 standard) This product has a sealed waterproof elastic joint seal materials, when both sides of the side seams from the increase beyond the elastic recovery when flexible waterproof material, because the material has a water swelling properties, expansion of the material within the scope of the role of water can still start and end the expansion body still has rubber-like properties, more water, acid and alkali. Widely used in construction joints underground railways, tunnels and concrete, expansion joints, cracks. 2, YHJ-10.1 EPDM rubber waterproofing membrane (Executive GB18173.1-2000 Standard) This product has excellent resistance to ozone aging properties of EPDM rubber as the main raw material, combined with butyl rubber, natural rubber and carbon black, curing agents a variety of materials, mixing, rolling, curing and other processes to obtain high-grade waterproofing membrane. It not only has high tensile strength, but also has excellent elongation, spring rate and low temperature performance, and it has a particularly excellent resistance to ozone aging properties is unmatched by other waterproofing membrane, the first demonstration by the US water sector development of such products, and its life of up to five years or more. So it is widely used in building water sector for quality waterproof material most demanding major projects, such as the central grain storage, nuclear power plants, museums, stadiums, subways, tunnels and so on. 3, two-component polyurethane sealant (Executive JC482-92 standard) is a two-component polyurethane sealant component A containing an isocyanate group (NCO) plus contains a curing agent, a reinforcing agent, thickener, filler material B component composition. When used according to the specified mixing ratio by a crosslinking reaction solidified into a flexible, strength, adhesion exceptionally strong sealing material. The products are mainly used for building settlement joint, expansion joints, construction joints, airport runways, bridges and other parts of the seal seams. Fifth, Construction Technology 1, second floor corridor grassroots joints 1.1 Requirements: separated by cutting machine cut at expansion joints on each side of 50cm (to prevent damage to adjacent marble playing chisel), and then at intervals between cut and expansion joints marble and mortar layer destroyed, until the base layer (concrete floor surface) to clean up. 1.2 The expansion joint on both sides of 10cm wide hit "V" shaped mold vertical depth 5cm. 1.3 with cement mortar will be labeled the "V" shape on both sides of the leveling layer. 1.4 In the bottom of the joints with 50 × 50cm water expansion of the seal fitted at the end. 1.5 sealant to seal the structural layer two-component polyurethane sealing, compaction. 1.6 laying YHJ-10.1 EPDM rubber waterproofing membrane 1.6.1 grassroots cleanup. The grass surface projections and other leveled and dust debris thoroughly cleaned. 1.6.2 Tu primary treatment agent. Brushing primary treatment agent using the construction method, brushing should be uniform. 1.6.3 painted grass adhesive. Before the base adhesive applications may require stir before use, it was painted in the grass and the bottom surface of the web. Brushing should be uniform, missed the end, not accumulation. 1.6.4 laying membrane. Glue about 20 minutes, after the basic sticky hand while pressing the side purge air, after bonding should then roll rolling again, firmly bonded without wing side, can not afford drums, then sealed with a polyurethane sealant. 1.7 test the water after 24 hours, waterproof protective layer. Marble ?? 1.8 with 1: 2 cement mortar paved about 20 mm, then cover with a marble is horizontal to gently, do not let the tool to scratch the surface, and gently press or by hand with a rubber hammer to gently knock Click marble, be sure to make it smooth and firm bond with the ground, no voids, or easy to break. To always use a soft cloth like cotton yarn extrusion cracks slurry will clean laying. After laying, you can regularly find wax in the board to ensure its bright sheen. 1.9 Finally pouring polyurethane sealant. 2, floor maintenance plasterboard. 3, floor joints. 3.1 Substrate requirement ?? separated by cutting machine cut at expansion joints on each side of 50cm (to prevent damage to adjacent tiles playing chisel), and then cut the brick and mortar layer and expansion joints between every other place to drop until the grass (concrete floor surface) to clean up. See above 3.2 (1.2-1.7) 3.3 3.3.1 before laying tile laying tile first soak for an hour, to prevent cracking, pay attention to the same type and size of tiles affixed in the same area while laying. 3.3.2 Construction ground to clean up, if there is no serious ground empty recess, can be carried out bomb line construction. 3.3.3 Pull the construction plane diagonal to find the center, according to the design pattern, with cement mortar (cement and sand ratio of 1: 2) as an adhesive tile from the center to the surrounding light hand pressure or gently tapping with a rubber hammer, with the ground cement. 3.3.4 When laying, you must complete with cement infill shall gaps between tiles and ground. Otherwise, after the cement dry, easily broken people step up. Sixth, quality materials: 50 × 50mm water expansion of the seal, YHJ-10.1 EPDM rubber waterproofing membrane, two-component polyurethane sealant must provide inspection reports, instructions for use, the Party approved before use. Seven finished work product protection measures to protect the waterproof layer is very important, during construction, must develop targeted protection measures, such as setting up the cordon, non-waterproof construction workers allowed to enter.
