Some excavators are born for construction, helping new buildings rise from the ground; some excavators are dedicated to destroying, demolishing old buildings.For demolition boom excavators for dry demolition operations, the shift fee is much higher than that of ordinary ones, and most of them are contracted, and the wages of the operators are often more than 10,000 yuan.
The reason why the cost is so high is that demolition is a high-risk operation, which not only tests the courage and skill of the pilot, but also tests the driver's judgment and experience of the actual situation. If you want to gain a foothold in this field, you must understand the relevant experience and skills.
What equipment is used for demolition
As the saying goes, "Don't buy porcelain without diamonds." To complete the high-tech and difficult task of demolishing a building, there must be someone who takes advantage of it. Common demolition equipment includes special demolition boom, breaker excavators, and dynamic compactors. Different equipment is suitable for different working conditions.
The demolition boom is a construction machinery specially designed for demolition, and the difference from ordinary excavators is mainly in the boom and attachment parts. The demolition machine has a three-section extension arm, and the working range can cover 5-10 stories high; the front end is usually equipped with powerful hydraulic tongs, which can cut reinforced concrete and tear the building to pieces.
Excavators with breakers are widely used in demolition operations and are the main demolition equipment for low-rise buildings. Under the heavy blow of hydraulic breakers, reinforced concrete has no power to resist.
The heavy hammer hammer type dynamic compaction machine is mainly used in soil compaction operations, and it also has a magical demolition effect for the bottom building. When the huge pendant hammer hit the building, the destructive effect was very shocking.
What are the postures of demolition work
The most common demolition posture is that the demolition boom excavator stands downstairs and uses the large and small arms to touch the building. The demolition machine is generally from the top to the next floor, as long as the distance from the building is generally safer. Breaking hammers and dynamic compactors are generally started on the bottom and middle floors of the building, and you need to pay special attention to the sudden dumping of the building.
In many demolition operations, we often see excavators being hoisted to high-altitude buildings and demolished from top to bottom. Although this is a little safer than hollowing out at the bottom, high-altitude operations also have great hidden dangers. If the building collapses, the excavator faces great risks.
There is also a special posture. For special buildings such as high-altitude chimneys, it is too dangerous for the excavator to remove it from below, and it is impossible to settle on it. Therefore, people generally use a crane to lift the excavator and let the excavator work in the air. This position requires the use of a small excavator, and the driver must have extremely high guts and skills, and most people don't dare to make this money at all.
Precautions for demolition operations
Safety measures must be taken in demolition construction site. Demolition boom excavators must have protective devices, site personnel should wear safety helmets, and safety belts for high-altitude operations; eye-catching safety signs should be set up on site, and safety maintenance should be done. Non-workers are not allowed to enter.
Before demolition, the surrounding environment should be checked and cleaned, and the surrounding pipeline network, lines, water and gas supply, underground construction and other safety hazards should be eliminated.
Demolition sites must be directed by a dedicated person, and there must be sufficient estimates of risks, and behaviors that exceed safety limits must be resolutely eliminated.
