Demolition of concrete ramp - blasting concrete in the building

Project description

Demolishing a concrete ramp is often a major challenge, especially when it comes to doing it efficiently and safely. The use of swelling explosives offers a modern and environmentally friendly solution. These explosion-free explosives, also known as blasting concrete or swelling explosives, make it possible to demolish the concrete ramp in a controlled manner and without the negative effects of conventional blasting methods. Chemical blasting minimizes vibration and noise, making it an ideal choice for urban areas or sensitive environments. Swelling explosives are characterized by their ability to shatter large amounts of concrete through controlled expansion without creating dangerous shock waves. This not only provides safety for workers, but also protects adjacent structures from damage. When planning the demolition of a concrete ramp, it is important to think through all the steps carefully and select the best methods to achieve an optimal result.

Project schedule

The demolition of a concrete ramp with swelling explosives requires precise planning and execution. First, a thorough analysis of the existing concrete is carried out to determine the size, shape and structure of the ramp. This data is then used to create a detailed drilling plan. The drill hole diameter must be between 25 mm and 45 mm in order to ensure an optimum effect of the swelling explosive. The distances between the drill holes should generally be ten times the diameter. These measures are crucial for even pressure distribution and efficient crack formation in the concrete. Once the plan has been drawn up, drilling of the holes begins. It is important that the minimum hole depth is at least five times the diameter. After drilling, the holes are filled with expanding explosive. The recommended mixing ratio is 1.2 liters of water per 5 kg of swelling explosive. This mixture is crucial for the expansion of the explosive and enables effective crushing of the concrete. After the boreholes have been filled, there is a short waiting period during which the swelling explosive is activated. During this time, the pressure in the concrete expands, causing the ramp to break up and be removed in a controlled manner. This entire process ensures a smooth and safe demolition of the concrete ramp.

Drilling information

Drilling information plays an essential role in the demolition of a concrete ramp with swelling explosives. Choosing the right drill hole diameter and the correct spacing is crucial for the effectiveness of the method. The following guide values apply to material consumption per meter of drill hole: a diameter of 25 mm requires around 0.9 kg of swelling explosive, while 30 mm requires around 1.24 kg. For 35 mm, the consumption is 1.68 kg, for 40 mm 2.2 kg and for 45 mm even 2.78 kg per meter. These values are important for planning material requirements and help to keep costs under control. The correct arrangement of the drill holes is crucial to ensure even pressure distribution. A strategic pattern is usually chosen to ensure that the pressure in the concrete is evenly distributed and cracking is optimized. This achieves efficient crushing of the concrete and speeds up the entire demolition process.

Consumption

The consumption of swelling explosives when demolishing a concrete ramp depends on various factors, including the size of the ramp and the drill hole diameters used. On average, the consumption is around 10 kg of swelling explosive per cubic meter of concrete removed. Careful planning of material consumption is crucial to avoid unforeseen costs and maximize the efficiency of the project. A precise calculation of requirements ensures that sufficient swelling explosives are available to successfully complete the project. Choosing the right material and accurately calculating consumption is also crucial for safety. Too little swelling explosive can result in the demolition not being fully successful, while an excess of material causes unnecessary costs. Careful planning and precise calculation can optimize consumption and increase efficiency.

Time / Costs

Demolishing a concrete ramp with swelling explosives is a cost-effective method that saves both time and money. Compared to traditional demolition methods, this explosion-free technique is significantly faster and safer. The ability to work without the usual risks of explosions significantly reduces the overall duration of the project. In addition, potential damage to adjacent structures is minimized, further reducing overall costs. The time it takes to demolish a concrete ramp depends on several factors, including the size of the ramp and the geological conditions on site. However, with thorough planning and the application of the right techniques, the work can be carried out efficiently, resulting in high client satisfaction. By using swelling explosives, the construction industry can benefit from a modern, environmentally friendly and effective method that not only increases safety, but also saves costs and time.

Expert opinion
