Boiler Chimney Removal Process
The construction safety steps are as follows:
1.1 When using temporary personnel and goods dual-use elevators, eternal (temporary) escalators, chimneys, and demolition equipment, it's essential to ensure that workers can climb safely. Before the resettlement process, strong bindings are usually placed on the ground for stability. An east-west ladder is temporarily fixed on the side of the steel column. After use, the essentials of dismantling should be carefully followed to avoid any potential hazards.
1.2 The flat channel method is often used in situations involving east-west scaffolding channels, steel pipe scaffolding, device channels, and handrail ropes. In areas without a quiet passage, the handrail rope is created by threading a steel wire rope or nylon rope through the welded joints of the steel columns at a certain height from the steel beam. This allows construction workers to walk on the steel beam with a quiet belt and support rope, ensuring safe movement and stability.
1.3 When constructing an operating platform between three steel columns, welding and fastening must be done carefully. The operating platform must be equipped with proper tools for the welder. It is common to either build an east-west platform or use steel pipes to create a secure structure. Before lifting, the column should be properly secured to prevent accidents during the lifting process.
1.4 The connection between beams and columns typically uses high-strength bolts or welded joints. These nodes are handled similarly to steel hanging baskets, which can be hung directly on the steel beams. This makes the operation more flexible and easier to move around during the demolition process.
1.5 During chimney demolition, it’s standard practice to set up floor-level nets, vertical protective nets, and pick-up nets. Floor-level nets can be placed on the surface of the steel beams or attached to the lower flange hooks. They can also be positioned under the scaffolding channels. Vertical nets and pick-up nets provide lateral protection, enhancing overall site safety.
4.1 During the chimney demolition stage, three-dimensional staggered work is common on the site. Some areas may have gaps in the quiet net, leading to risks of falling debris. To address this, a break layer is necessary. Metal profiled steel plates are often used as a break layer during chimney demolition. These plates are inserted into the chimney area, helping to reduce noise and prevent dangerous leaks during the dismantling process.

The pin refers to the connection between the internal circuit of the integrated circuit (chip) and the peripheral circuit, and the pin constitutes the interface of the chip. According to the function, the pins of AT89S52 can be divided into four categories: main power supply, external crystal oscillator or oscillator, multi-function I/O port, and control, strobe and reset.
