Sharing of Weifang Brick Chimney Demolition Construction Scheme

Construction sequence:

Set safety ring around the lower surface of the chimney of "Jiangsu Fayuan High-altitude Engineering Co., Ltd." → The opening of the smoke outlet is 1x1.5 → Chimney Demolition → Removal of water film with granite for dust removal → Site cleaning.

Third, the main construction technology:

1. The 41-meter-high brick chimney and granite water film dust removal are all removed manually, and the foundation is not removed. The safety line is surrounded by safety ropes, and there are special personnel to inspect it, thus protecting the safety of pedestrians. Clear traffic signs should be hung on the safety ropes, and red lights should be hung at night.

2. firstly, put a safety steel pipe or a Chinese fir pole climbing at the top of the chimney, tie it firmly, and lock people's safety on the steel pipe for construction and demolition. During the construction, the top of the chimney is laid flat with a piece of 41×251×3111mm board so that the construction workers can operate safely. All the bricks demolished by electric pickaxe come down from the chimney. The hammer cannot operate in the middle of the chimney demolition because of the thickening of the chimney wall, so the gear jack must be used, and the channel steel and steel pipe should be welded for rail demolition.

Fourth, the construction method:

1. Before manual demolition, the vent is used as the slag outlet, and a small excavator is used for slag discharge.

2. After the construction personnel stand on the scaffold and hang the safety belt on the steel pipe, they will dismantle the cylinder block by block from the outside to the inside with a pneumatic pick and a hammer, so that all the ballast blocks will be buried in the cylinder;

3. Demolition operation is strictly prohibited at night, and slag removal can be arranged at night, which is beneficial to continue demolition during the day. Demolition and slag removal are strictly prohibited at the same time;

4. The scaffold is lowered with the lowering of the construction surface, but the scaffold must always be meters to meters higher than the construction surface to prevent the slag from flying out of the scaffold protective layer;

5. The oxygen and acetylene bottles are placed on the working platform, only the gas cutting gun is on the construction surface, and the lightning protection antenna is burned while being dismantled (the truncation length is not more than meters).

5. Safety measures:

1. Construction personnel should experience on schedule, always know the employees' physique and thoughts, and prevent people with poor hearing and poor eyesight from participating in the construction.

2. Strive to create a good construction environment, so that employees can make more contributions to the project, ensure that they don't drink alcohol before work, don't go to work in spite of illness, work regularly and rest on time, strictly implement safety rules and regulations, and formulate emergency plans for the project in detail.

3. The construction personnel must hold relevant certificates, implement the operation regulations for high-altitude suspension, wear protective equipment, enter the construction site according to the route specified by the owner, strictly implement the safety management rules and regulations of Jinan Yuxing Chemical Co., Ltd., wear safety helmets when entering the construction site, wear complete protective equipment, and wear gas masks and rubber gloves to fasten your seat belts.
