A leak-trapping and strengthening internal treatment structure and construction method for the external wall of the structure

Abstract

The invention discloses a leakage repairing and reinforcement internal management structure of a constructed external wall and a construction method. The construction method comprises the following steps: firstly, chiseling off one part with the thickness of 10cm-15cm of the inner surface on the inner side of a leakage external wall; carrying out temporary water stopping on a leakage position and punching an inclined hole in the wall body of a non-basement external wall to discharge water in a low-outside and high-inside manner; cleaning a base layer and coating and brushing cement to realize permeable crystallization; secondly, sticking a water-stop strip which is swollen when meeting water at a part which is 2cm-5cm far away from the edge in the chiseled-off wall surface; planting steel bars 5 in the position of the chiseled-off wall surface and arranging distribution ribs; thirdly, coating hand throwing type early strength impermeable concrete on the wall and reserving a groove in the combined part of new and old materials; and finally, filling the groove with a leakage stopping agent after the concrete is finally condensed. The management method disclosed by the invention has the advantages of reasonable design, low cost, convenience in construction, convenience in operation, structure reinforcement, no need of a supported formwork and resource saving; and internal management is adopted so that the construction safety is high, the difficulty of external wall leakage at present is effectively overcome, the internal management of the external wall leakage is realized and the leakage repairing and reinforcement are realized.

Description

technical field [0001] The invention relates to the technical field of waterproofing and leak repairing of buildings, in particular to a leak repairing and strengthening internal treatment structure and a construction method of the outer wall of a building. Background technique [0002] The external wall is a major difficulty in waterproof construction. In recent years, the leakage of the external wall of the building has been serious. In order to fundamentally solve the problem of cracking and leakage of the external wall, and considering the safety and convenience of construction, the leakage is repaired and the internal treatment is carried out. The external wall must be carefully and meticulously required in the construction process. If there is a construction error, it will easily cause leakage. The current construction management is difficult to meet the requirements; And other factors, will cause the external wall to crack, resulting in leakage; and the external wall ...
