Chiang Khong, clean tank, requiring no dust, dirt; 5. With quick-setting cement caulking, pipe, require tight pressure paste; 6.LB-91 modified epoxy resin chemical injection slurry grouting pressure 0.4 ~ 0.5mpa, after reaching the pressure, closed tube until condensate; 7. condensate to be 8 to 12 hours, check orifice bubble tubes, not full secondary or repeated grouting to a slurry bubble tube full; 8. condensate to be 3 to 7 days after the demolition of the tube, remove caulking early strength cement, epoxy mortar Swiss caulking of joints to fill the slot, tightly pressed against the concrete requirements to fill, surface color, flatness should be consistent with the original surface of the tube sheet 9. After the condensation surface modification using the wet milling. 1.1 tablets jumped block processing (seepage state) 1. cleared jump blocks and cut loose concrete pieces, find the leak location cloth drilling; 2. Using quick-setting cement sealing pipe; 3.LB-91 modified ring epoxy resin chemical slurry injection pressure 0.4 ~ 0.5mpa, after reaching the pressure tube to be closed condensate; 4. condensate to be 8 to 12 hours after the inspection bubble tube orifice, the secondary is not full or repeated grouting, to Bulb full; 5. 3 to 7 days to be split condensate pipe, clean the surface; 6. Remove the base surface, requiring clean, no loose particles; 7. Using LB-91 modified epoxy coated concrete slurry chemical injection base surface, requiring uniform, not grin; 8. epoxy mortar repair defective bits requires smooth and no bump; 9. seam surface modification using the wet milling; 10. maintain color consistency and tube sheet repair at the surface color is required water mud plaster for repairs can be trimmed. Before plastering, needed to repair a wire brush for cleaning moist, and then 1: 2 to 1: 2.5 grout clean surface dressing. 11. strengthen conservation efforts after plastering the initial setting. 1.2 pairs of bolt holes leakage 1. unloading of pull-bolt nuts; 2. Remove the bolt holes in the floating mud, dirt, rust; 3. With the ball at one end outlet obstruction blockage bolt holes, and from the other end of the exit insert small tubes. Using early strength cement seal tightly pressed against the requirements; 4. In the corresponding seams on both sides of the bolt, drill hole terminated, pore size 15px, hole depth 200px; 5.LB-91 modified epoxy chemical slurry injection, pressure 0.3 ~ 0.4mpa; 6. condensate to be 8 to 12 hours after the inspection bubble tube orifice, the secondary is not full or repeated grouting to bubble tube full; 7. 5 to 7 days to be split condensate pipe, pull a ball plunger, remove the bolt holes in the early strength cement, installed on the bolt cap, replace gasket (using chlorinated polyethylene rubber mat). Patch 2.1 Segment lining segments according to the design requirements for the design, lining the surface should be dense, smooth, flat, edges intact without defects. Lining for assembly before, should be strictly checked and flat gaskets on both sides of the corner slots may not have peeling, defects, missing corner with a big repair mortar repair, seal on both sides of the trench bottom surface pitting with greasy dry grout repair fill, inspection and approval before use. 2.2 improper reasons a damaged piece, segment stripping, storage, loading, transportation and other process operations appear damaged corners; 2, Segment amount of eccentricity in the big shield tail, the tail pipe piece and shield bump phenomenon occur, as well as promoting Shield Shell Shield bad card segment; 3, when the mutual position of the tube sheet assembly dislocation between the tube sheet and tube sheet does not form a surface contact, when the shield forward to produce concentrated stress at the contact point, Segment angle caused fragmentation; 4, before a ring segment of a torus uneven, so that after a unilateral contact ring segment, in the role of the jack just like a seesaw, segment subject to additional fracture moment. In torus uneven seams capped block adjacent blocks, will lead to the adjacent block corners fracture; 5, assembled a good amount of opening of the adjacent block is not enough, when you insert the block cap gap is small, such as the forced insertion, the lead capped block adjacent segment or segments angle block caving; 6, erector when operating speed is too large, segment collision when assembled, corner caving; 7, vehicular tunnels mechanical or artificial collision damage, especially in the corners place. 2.3 patch a damaged segment, prefabricated segments venue when releasing water bubbles can be mild defect repair of defects should be reported to a larger segment of Mill repair engineer's approval, in not qualified to isolate and identify the line before. 2, due to the tube sheet during storage, transport process is likely collision damage, so in addition to the repair work carried out at the time of releasing the segment should also go to the storage site inspection and repair minor defects segment again, seriously flawed isolation. 3, segment should be checked again before leaving the factory to be shipped segment, and in the first three days of the shipping segment repaired before shipping after passing inspection by quality control personnel. Repair before 5, the installation process larger tube defects should be reported to the Engineer-chip inspection approval; 4, approach and installation of tube sheet strict inspection, damage, serious cracks abandoned segment, isolate and identify . Repair process using a professional repair personnel, using epoxy mortar. 2.4 Methods 2.5.1 Materials 1 sheet repair, types: 1) glue stick Huang supplements (Sika Latex); 2) 42.5R two whiteness of white portland cement; 3) 42.5RⅡ type of portland cement; 4 ) water; 5) E44 type epoxy resin 6) EP-type curing agent 7) 690 diluent 8) 0.2mm (through the screen) river sand, 0-3mm sand. 2. Technical requirements: 1) repair mortar and grout repair using tap water, sand needed clean water, particles were irregularly shaped, cement line with regulatory requirements. 2) need to sand the epoxy mortar fried dry or drying, mixing ratio in accordance with, pay attention to controlling the amount of spices, be sure to use completed within the stipulated time use. 2.5.2 fixes a mix concrete, grout repair (repair minor cracks and subsidence of not more than 2mm of bubbles, etc.): white cement 2kg, ordinary cement 1kg, glue stick Wong supplements 0.54L, water 0.48L; 2, repair Mortar (repair than 2mm bubbles, pores, cellular, etc.): white cement 2kg, ordinary cement 1kg, sand 7.5kg, glue stick Wong supplements 0.72L, water 0.3L. The repair manual repair mortar or grout stir for about 2 minutes. 3, epoxy mortar (repair segment chipping, chipping, etc.): E44-type epoxy resin: EP hardener: 690 Thinner: 42.5R cement: 0.2mm (through the screen) river sand = 1: 1: 0.1 (unit: ml): 0.7: 1.7 (unit: g) 2.5.3 patch repair method segments can be processed in accordance with the following different cases: small cellular segment, small bubbles (with repair grout). ⑴ water to the site in need of repair and humid (moist to achieve uniform absorption saturation effect, but not in water); ⑵ repair grout sponge glue evenly on both sides of the painting, until the cellular bubbles are filled with smooth ; ⑶ require repair after dry surface segments consistent color, smooth surface, cellular repair after the bubble tube parts to piece seamless, not visually distinguishable. Segment large bubbles, holes (with a repair mortar, hole diameter 10-25mm, 10mm depth below) ⑴ water to the site in need of repair and humid (moist to achieve uniform absorption saturation effect, but not in water); ⑵ use The repair mortar sharp spoon filled bubbles, holes in until almost fill; ⑶10 ~ 15 minutes after the repair mortar repair inspection combined with the original concrete, if combined with tight again fill with repair mortar leveling wipe smooth, if peeling need to re-patch repair mortar knock. ⑷ repair achieve the effect: After repairing old concrete dry concrete linked closely together, the same color, the surface without cracks, no bump, no shadow, smooth, with Trowel handle tap the site no loss, no peeling, no cracks. Tube sheet collapse, chipping (with epoxy mortar) epoxy mortar with a high-strength, fast-setting, water and other characteristics. The preparation, sand subject to stem speculation deployment, operation, maintain good ventilation, deployment of a good mortar should be completed within 30 minutes use. ⑴ tools to chipping, chipping all parts of exposed concrete rubble knocked until the repair surface clean; ⑵ after mixing epoxy mortar will smear on the joints, with Trowel, flat boring early modified molding; ⑶5 minutes After checking the binding of concrete. If combined with tight again fill leveling smear smooth, peeling or cracking occurs if you need to re-patch repair mortar knock; ⑷ repair should be achieved: old concrete closely, strength to meet the requirements, the same color, the surface without crack no bump, smooth, with Trowel handle the heavy percussion parts no loss, no peeling, no cracks.
