The main point of engineering care for the reinforcement of chimneys in yundong
The safe and stable operation of chimneys as an important component of industrial facilities is related to the production of enterprises and the surrounding environment. As a coastal industrial city with a large number of chimneys, regular reinforcement of maintenance and care are key to security。
I. Daily inspections
The chimney appearance needs to be examined on a weekly basis, focusing on cracks and corrosion. According to the xx building inspection agency, 80 per cent of chimney accidents originate from early small cracks that were not addressed in a timely manner. When a slight crack has been discovered, a special seal can be used to temporarily block the damage to avoid rain infiltration。
Ii. Structure strengthening methods
1. External carbon fibre sheet: applies to horizontal crack restoration, which enhances concrete strength. Construction is carried out by grinding the surface and then pasting the specialized glue, solidification and forming the overall stress structure。
2. Add a reinforced ring: a heavily worn chimney at the bottom, reinforced by a ring steel plate, and enhanced wind resistance through a bolt fixed and dispersed pressure。
Iii. Preservative measures
The high salinity of coastal areas is prone to erosion of the outer walls of the chimney. The following methods could be used:
- spraying sands and stains with salt resistant paint
- preservative layer tests every three years
- add acid-resistant liners to the inner wall for extended life
Iv. Safety norms for high-altitude operations
The maintenance of chimneys, mostly at high altitude, requires strict enforcement:
- pre-operational high-altitude operating permits
- with double hook seatbelts and safety ropes
- set up a perimeter on the ground
- bad weather (wind 6 class) stopped
V. Periodic maintenance cycles
- minor corrosive: half-yearly examination
- medium damage: quarterly special tests
- major maintenance: third-party agencies are invited to issue security assessment reports
The maintenance of chimneys will need to be accompanied by a programme for the selection of qualified professional construction teams. Daily maintenance and scientific conservation will enable chimneys to play a long-term stabilizing role and ensure the safety of industrial production。
