Foundation Type

The foundation consists of 2 types namely Type:

The first post we will review the most important part in a building. That is the foundation. The foundation is the most important part in setting up a building, without a solid foundation, the building will undoubtedly stands strong. The foundation is divided into two parts, namely the shallow foundation and deep foundation. To find out the following will be reported.

A. Shallow Foundations

Shallow foundations are usually made near the soil surface, generally less than one third the depth of the foundation established foundation of width up to a depth of less 3 m. The depth of the shallow foundation is not a standard rule, but it is as a guide. Basically, the surface loading or other surface conditions will affect the bearing capacity of shallow foundation. Shallow foundations are usually used when the soil surface is strong and rigid enough to support the loads imposed where it supports the type of structure is not too heavy and not too high, are generally not suitable shallow foundation in weak or compressible soil is very poor, such as soil density poor, shallow foundations are also not suitable for the type of peat soil, subsoil young alluvial deposits and soil types, etc..

Type - Type of Shallow Foundations

1 Pad foundations (Foundations Tread)

Foundation footprint (foundation pad) is used to support an individual point load such as structural columns. The foundation of this pad can be made in the form of circular, square or rectangular. This type of foundation usually consists of a reinforced concrete layer with uniform thickness, but the foundation pad can also be made in the form of multilevel or hunched if this foundation is needed to spread the burden of heavy columns.
Foundation footprint as well be applied in shallow foundation can also be used for deep foundation.

2. foundation or foundation elongated Strip (Strip foundations)

Foundations pathway / foundation elongated (sometimes called continuous foundation) is a type of foundation that is used to support the aft load or load line, either to support the wall load or load column where the column placement in close proximity and functional columns supporting the load is not too heavy so that the foundation footprint is not needed. Foundations pathway / foundation elongated normally be made in the form of elongated rectangular piece or trapezoidal. Usually used for foundation walls and columns practical. Materials for this foundation can use the pair broke shoes, stone, cast concrete without reinforcement and can also use brick masonry with a record does not support structural loads.

3 Foundations Mat (Raft foundations)

Foundation mat / raft foundations are used to spread the load of the structure over a large area, usually made to all areas of the structure. Raft foundation is used when column loads or other structural loads and foundation pad adjacent to interact with each other.

Raft foundation normally consists of a reinforced concrete slab that spans a specified area. Raft foundation has the advantage of reducing the concrete slab where the local decrease would offset the differential movements between loading positions. Raft foundations are often used on soft or loose soil with low endurance capacity because radft foundation can spread the load over a large area.

B. Foundations In

The foundation is a foundation established in the soil surface with certain into which the basic foundation bearing capacity is affected by structural loads and ground conditions, the foundation is usually installed at a depth of more than 3 m below the ground surface elevation. The foundation can be found in the form of pile foundation, walls or foundation piling and caissons compensation. The foundation can be used to transfer the load to deeper layers to achieve certain to come into the land that supports the type of load power structure building so that the type of soil that is not suitable near the soil surface can be avoided.

Type - the type of foundation in:

1 Pile Foundations

Pile foundation is a type of foundation that is made in the form of a slim intended to transmit the load through layers of soil types with the type of low bearing capacity to achieve a deeper type of soil or rock layers that have a high bearing capacity. Pile foundation is used when the consideration of economic value, construction or land desired to transmit the load beyond the reach practical than using this type of shallow foundation. In addition to supporting structures, pile foundations are also used to support the weight of the structure against the force of lift and also help in the fight against the power structure of the lateral force and roll style.

Pile foundation can be found in various types such as v pile and concrete where the stakes. Structurally foundation pile before the load of the column is forwarded to the pile, the pile itself made above link construction which is usually called the pile cap.

2 Foundation Piers (diaphragm wall) is the foundation to continue the heavy structural loads are made by way of digging in, then the structure of the pier foundations were mounted to the quarry. One advantage is that the foundation pier foundation of this type is cheaper than building a foundation with a continuous foundation type, only the losses suffered if the slab is the foundation that has made the size of the power shortage is not a normal type of foundation. Standard pier foundation can be made from pre-cast reinforced concrete. Therefore, the planning rules pier foundation is concrete block diafragman follow any measure height foundation planned. Pier foundation can be visualized as a table form, is a system of vertical column structure made of reinforced concrete buildings placed under embedded below the soil that has been excavated. The concrete slab diaphragm transfer building loads to the ground. Beam is built on top of a vertical diaphragm walls (foundation pier) that hold the wall or structure. Many homes are fully supported with this type of foundation, where concrete is also useful as a wall mounted in the basement, where the space is used as a storage shed or garden. Concrete pier foundation is usually made in the form of pre-cast in a variety of sizes and shapes, which are often found in the form of an elongated square with a height corresponding to the depth of the required size. But concrete can also be made in the form of a sphere. Once the concrete is dry enough then put into the soil that has been excavated and arranged continuous. After a well-structured and then just continue with the construction thereon.

3 Foundations Caissons (Drill Pile) is in the form of a foundation built on the ground level, the foundation in place up to the required depth by making a hole with drilling or dredging soil system. Once the depth of pile foundation has been established then performed by casting concrete in the holes that have been drilled. Drilling system can be done in different types of systems both manual and hydraulic systems. Large diameter and depth of excavation and concrete reinforcement system is also designed based on soil bearing capacity and the load to be carried. Functional is also almost the same foundation pile foundation which is also intended to support the weight of the structure against the force of lift and also help in the fight against the power structure of the lateral force and roll style
