Based on years of experience and actual conditions, the construction is carried out using the suspended work method without scaffolding.

Brush the shipping mark:

Elevators working on chimney tops should be securely fastened with safety belts while operating on the roof platform.The φ20 nylon rope is securely tied and lowered onto the triangular support of the chimney platform. Additionally, a φ20 nylon rope auxiliary safety line is used, with each person's safety belt locked onto the auxiliary line using a self-locking device (totaling three φ20 nylon ropes for two people). This enhances safety coefficients and ensures security.

Construction workers use seated elevated boards to access.The U-bolt installation is conducted from top to bottom, ensuring smooth progress for the construction crew. During continuous production, the first step is to treat each exposed reinforcement on the outer wall from top to bottom, removing any loose parts. The exposed reinforcement is then manually de-rusted and polished until the surface is free of rust. To repair the exposed reinforcement and loose areas, a polymer reinforced patching mortar is used (due to the strong bond between the polymer patching mortar and cement surface, it is not easily detached, but there will be a color distinction).All items are painted twice overall, colors determined per Party A's request. At the end, the company logo and name are added on the side facing the road of the chimney (each on two sides).

Chimney platform and ladder guardrail maintenance:

Two pieces20#Lower and secure the nylon rope on both sides of the ladder at the top platform of the chimney. The construction was completed using the suspended seat board method for elevated work.

If there are solder joints that have come loose, perform welding repairs and replace any necessary parts. First, scrape off the rust layer from the platform and ladder guard mesh using a scraper. Then, brush away the surface rust with a wire brush. Apply the anti-rust paint first, let it dry, and then apply two coats of primer. After the primer dries, paint two coats of topcoat (note: wait at least eight hours between coats for the primer to dry).

   Safety Measures

1Preparation for construction should be well-done prior to commencement.,Wear a safety helmet,Fasten your seatbelt.

2Before workers climb to the top of the chimney platform for operations, they must secure their safety belts to the railing of the platform.

3Nylon rope used during construction work,All safety lanyards must be securely tied to a top, reliable anchor point and fastened around with a wire rope to prevent any accidents.

4Construction personnel operationUThe form safety lock扣 allows the working rope to descend the work level slowly. Construction personnel perform the work using a seated ladder. The construction nylon rope diameter is not less thanΦ20mmAnd undergo overload impact tests. Each construction worker must be equipped with double safety measures while operating on a main working rope before entering the construction site, (each...)2One nylon rope is shared for the secondary safety (three ropes for two people).

5Ensure that the nylon rope's anchor point is secure during each move, and reinforce it around the top edge with钢丝绳. Upon reaching the desired working position, also inspect the suspension mechanism before proceeding with the construction.

6The construction unit ensures completion within the specified period by Party A.
