Sharing of Construction Scheme for Demolition of Brick Chimney in Weifang

Construction sequence:

The safety circle around the lower part of the chimney of Jiangsu Fayuan High-altitude Engineering Co., Ltd. → Open the smoke outlet 1x 1.5m → Dismantle the chimney → Dismantle the granite water film for dust removal → Clean up the site.

Third, the main construction technology:

1, 40-meter-high brick chimney and granite water film dust removal are all removed manually, and the foundation is not removed. There are safety ropes around the safety line, and special personnel patrol to protect the safety of pedestrians. Clear traffic signs should be hung on the safety rope, and red lights should be hung at night.

2. First put a safety steel pipe at the top of the chimney or climb the Chinese fir pole of the ladder at the top of the chimney, tie it firmly, and lock the safety of people on the steel pipe for construction and demolition. During construction, the top of the chimney is leveled with a 40× 250× 3000mm wooden board, so that the construction personnel can operate safely. All the bricks removed by electric pickaxe came down from the chimney. During the chimney demolition, the hammer can't be operated due to the thickening of the chimney wall, so the gear jack must be used, and the channel steel and steel pipe should be welded when the track is demolished.
