The internal patching law is with the forcing pump the ceme nting material pressure concretes crack, renders the young or up and ing generation to sew up the function, and makes the original structure through its cementation to restore the integrity, this method is suitable for the crack opening is big, and durable and so on is influential to the structure integrity and the security, or has request and so on waterproof antiseepage crack patching. 4） Carbonized concretes repair technology It is refers to through restores the concretes the alkalinity (inactivation) or increases its impedance to enable the steel bar corrosion which the carbonization creates to obtain the containment technology. 5） Concretes surface treatment technology It is refers to uses cleaning up concretes surface stains, the oil mark, the residual as well as the other attachment and so on chemistry method, mechanical method, sand blasting method, vacuum cleaning method, injection method skill. 6） Coagulation mantle of soil seal technology It is refers to uses flexible methods and so on aquaseal backfill, polymer grouting, paint film to carry on the waterproofing to the concretes, moistureproof and against crack processing technology. Like the structure, the ponent shift the technology, the adjustment structure base frequency technology and so on. 7） Other technologies Like the structure, the ponent shift the technology, the adjustment structure base frequency technology and so on. 2 Brickingup structure Brickingup structure reinforcement method: The brickingup structure39。s reinforcement divides into when the direct reinforcement and reinforces two kinds 6 indirectly, the design, may act according to the actual condition and the operation requirements choice being suitable method. suitable for the brickingup structure direct reinforcement method 1) outside reinforced concrete superimposed layer reinforcement law This law belongs to the pound section reinforcement method one kind. Its merit is the construction craft simple, patible, after the brickingup reinforcement, the supporting capacity has enhances greatly, and has the mature design and the construction experience。 Is suitable in the column, the belt wall wall reinforcement。 Its shorting is the scene construction wet operating time is long, to produces has certain influence with the life, and after reinforcing the building clearance has certain reduction. 2) outside reinforced concrete mortar superimposed layer reinforcement law This law belongs to the pound section reinforcement method one kind. Its merit and outside the reinforced concrete the superimposed layer reinforcement law is close, but enhances the supporting capacity to be inferior to the former。 Is suitable in the brickingup wall reinforcement, sometimes also uses in outside the reinforced concrete when the superimposed layer reinforcement belt engaged column wall the both sides put on the wall stirrup the seal. 3) the addition holds the engaged column reinforcement law Thi
