in the operation process

in the operation process of the chimney anti-corrosion project, the height width ratio of the wall is not suitable to be higher than 1200 meters in rainy days. Before the rainstorm comes, dry bricks should be laid on the top of the wall to prevent the cement mortar from being washed away by precipitation, resulting in the collapse of the filling wall. Before hoisting the inner cylinder or storage tank of chimney, grasp the weather and change the information content gradually. The heat insulation and anti-corrosion of steel inner cylinder or storage tank of flue gas pipe shall be well done to prevent the difficulty of construction and the doubt of cost. According to many years of practical experience, the construction team has acquired a set of safe hydraulic jack up professional skills. The organization's emergency rescue and relief staff should prepare all rescue and relief materials to avoid unnecessary damage caused by diseases. The activity opens the chimney construction safety in summer, propagandizes and plans the fitness movement, the traveling staff safety guard understanding, avoids the sickness security duty imbalance. Safety measures for chimney anti-corrosion work at height 1) before chimney anti-corrosion construction, each personnel must be checked once, and blood pressure and heart should meet the physical standard of high-altitude operation. 2) During construction, all construction personnel must wear safety helmet and fasten safety belt. 3) All construction personnel are strictly prohibited from drinking alcohol before work; outdoor climbing construction is strictly prohibited when the wind force reaches level 6 or above; special construction personnel must hold the valid certificate of labor department and work with certificate. 4) All tools, materials and equipment used in high-altitude construction shall be fixed in strict accordance with regulations during hoisting and placing. Construction personnel must wear relevant labor safety protection articles to ensure that they can not fall down to damage the equipment and hurt the ground personnel.The construction procedure must be followed from top to bottom. At the end of construction on that day, daily safety summary shall be carried out, and rectification measures shall be taken in time if problems are found. When spraying the anticorrosion area of steel structure, pay attention to the wind direction, and the operator should sit in the downwind direction to prevent the paint mist from being blown to the unsightly granular surface under the UN sprayed paint film. If it is too far away, it is easy to hang; if it is too far away, it is easy to hang; if it is too far away, the anti-corrosion of paint mist chimney is uneven, and it is difficult to show pockmarks, and the nozzle is far away from the object surface, and the paint mist flies away on the way, causing waste. When spraying the dull wet paint, the anti-corrosion of chimney needs to be sprayed in sequence. When spraying to the two ends of the object point, the hand pulling the spray wrench should be tightened quickly to lengthen the paint mist, because the two ends of the object surface should be returned to take over the following spraying twice, so as to prevent the dripping and hanging. The basic regulation of the old chimney anti-corrosion is that when the cold acid liquid appears in the inner chamber of the chimney, the lining of the smoke exhaust pipe can not be eroded within the service life of the design scheme, and the structural safety of the chimney can not be lost due to the corrosion damage of the lining, and the cold acid liquid can not seep into the outer wall of the concrete structure, which will seriously damage the structural bearing capacity of the chimney. When the outer wall of concrete structure is eroded, the hidden danger of structure safety will be harmed immediately. In order to ensure the safety and credibility of its application, enterprises with building structure credibility inspection and evaluation qualification certificate should be invited to carry out credibility evaluation on chimney structure before the solution of chimney corrosion prevention. At present, the main components of raw materials suitable for old chimney anti-corrosion reconstruction in China are organic chemical epoxy resin and inorganic materials. The high-temperature resistance dominated by organic materials is weak, while the corrosion resistance dominated by inorganic materials is weakAnd good heat resistance, but poor adhesion, and easy to crack. Their composition will seriously damage the properties and performance of anti-corrosion raw materials, which should be comprehensively considered in the anti-corrosion reconstruction of old chimneys. Safety measures for chimney anti-corrosion climbing operation 1) before the chimney anti-corrosion construction, it is necessary to carry out an inspection for each staff member, and the heart rate and cardiovascular system should meet the physical specifications of climbing operation. 2) During construction, all construction workers must wear safety helmet and pay attention to safety. 3) All construction workers are prohibited from drinking before work; outdoor climbing operation is prohibited when the wind speed is above 6; special construction workers must hold the reasonable certificate issued by the health administration department and take the post with certificate. 4) All special tools, raw materials, machinery and equipment used in high-altitude construction shall be fixed in strict accordance with regulations during lifting and placing. Construction workers must wear relevant labor safety maintenance tools to ensure that they can not fall down and damage machinery and equipment and damage road workers. The top-down construction procedure must be followed. After the construction is completed on the same day, daily safety summary shall be carried out, and improvement measures shall be taken immediately if problems are found.
