The external wall tile maintenance programme, the cause analysis was examined on site, the site environment at the time of construction and the analysis of the reasons for the release of the empty drums of the external wall by the consulting professionals concerned, as follows: over-drying of the front-line brick leads to water recovery at the grass-roots level, resulting in the fall of the viscos and the grass-roots level due to, inter alia, the reverse friction resistance; 2, the disfigurement of the ash layer caused by empty drums; and 3, the temperature from the surface to the grass-roots level is soared and cool as to generate stress that if it is not sewn closely and is not fully saturated, there will be empty drums and cracks at this weak point. 2. The technical preparatory project department organized a cause analysis of the technical staff involved in the quality of the disempowerment of the external walls of the western survey 35#, 36# residential buildings, which, in conjunction with the inspection of the amount of bricks required for maintenance, provided a bottom line for the selection and technical requirements of the construction personnel. The main equipment for the construction and preparation of the labour force is the construction basket for the outer wall, which is planned to be used in order to avoid inconvenience and safety for owners. The labour force will arrange for the maintenance of four experienced operators. 3 material preparation of 45mm95mm bricks, tiles for adhesives, interfaces. 3 exterior wall maintenance construction method selected with the exception of empty drum-side bricks, which examine and process the ground-level paste bricks and sutures, the removal of empty drum-side bricks and the placement of blank drum-side bricks along their sides with a small cutting machine to cut them off along the bricks and carefully remove the face of the empty drums. 2. Inspection and processing of ground-level empty-drum bricks when it is finished, a small hammer is used to check whether its grass-roots base is loose, if the grass-roots base is loosely removed, then water is wetted, then the grass-roots level is repainted, first with the structural layer brushing interfaces, 1:2. 5 with the cement looking for layers, first with the anti-fisssile slurry, if the temperature layer is in place, then the surface should be cleaned, and the temperature layer should be checked for its integrity with the grass-roots strength and wire wire, and if there is damage to the retreading of the steel wire and the condensation nails, and then with the anti-fisile slurry, then the ground level must be painted before the final condensation. 3. Construction is carried out using top-down construction sequences for pasting of laminate bricks. The glue layer is about 3 mm thick. Bricks can be mobilized within five minutes of pasting and the width of the bricks, and attached to the line. In 20 minutes, vibrations or moving bricks are strictly prohibited. Bricks are thick and the width of the bricks should be smooth and even on both sides of the original wall. 4. A 3 mm round arc sewn between a brick sewn and a clitoris sewn in time to clear the slurry around a brick, so that it is clean and the surface clean. The stitches should be uniform to the original wall surface. 4. Quality standard 1 and pasting of bricks must be robust and free of quality problems such as slanting ambiguity and empty drums. 2. The surface is flat, clean, colour-consistent and clean. 3. Close, flat, wide and narrow, laced and edged. 5. Protection of finished products1 and timely clean-up of residual window frames and slurry on glass. 2. Pay particular attention to window glass during construction to avoid contamination and damage. 3. During the construction work, care was taken to destroy the first floor and other facilities. Vi. The facilities for the construction of safety-civilization projects1 and the construction of the basket should be secure and equipped for personal follow-up. 2. Exterior wall repairs should be carried out to protect against bricks and ash levels. 3. Grounds in the construction area should be secured and manned for observation. 4. Completion of work after completion of construction。
