The raft foundation gunite machine is a trickle process, in which two rows of compressed air from an air compressor, a stream of compressed air blowing material from the top of the rotor of the cyclone, and the other stream from the swirling flow to the nozzle are compressed Material blown out by air. The raft foundation gunite machineis divided into dry shotcrete and wet shotcrete. For dry-mix raft foundation gunite machine is add water to the nozzle, and for wet-mix lignite machines, add an accelerator to the nozzle. The raft foundation gunite machine is mainly used for dry mixed spiked shoes and wet mixed spiked shoes. It has obvious advantages such as advanced technology, perfect structure, stable performance, convenient operation and long service life. What is the basis of the raft?
A raft foundation (also called a cushion foundation) is a large concrete slab that can support a large number of columns and walls.
The slab extends to the entire building or at least most of the building, and has a lower contact pressure compared with the traditional belt or trench foundation.
Due to the speed and quantity of housing needed after World War II, the raft foundation has been widely used. The raft foundation is cheaper and easier to install, and most importantly, it does not require a lot of excavation work like a conventional strip foundation.
When is raft foundation used?
Nowadays, rafts are usually used when the ground is unstable or (for this reason) a normal strip foundation covers more than 50% of the ground area under the building. In some cases, there may be areas of movement in the formation (usually areas where mining occurs).
The raft foundation gunite machine is more commonly used in the construction of commercial buildings in the UK than in homes, but they work well in both cases. How does the raft foundation work?
The raft foundation distributes the weight of the building to the ground floor of the entire building. Rafts are placed on iron rods or scalp stripping beds, usually with thick edges, especially on very harsh ground. Rafts are ideal when the ground has a high load-bearing capacity and requires little work to get a solid foundation.
The raft foundation is constructed as follows:
The soil has been removed to the correct depth,
The bed is compressed by the plunger,
Place the rebar on the spacer above the base.
Pour concrete on the steel bars.
The foundation can be hardened by built-in ribs or beams during construction to increase strength and rigidity. The raft foundation gunite machine is widely used in mining, tunnels, culverts, subways, water conservancy projects, underground excavation projects, etc. If you are interested in the raft foundation gunite machine, please tell us your requirements and provide the corresponding product parameters and quotations. The email address is sales@leadcrete.com.
