Mat Floating Foundation

Comprising a deck box 3 4 chord square truss structure mono column and a mat foundation the mcp is able to operate in oil fields with soft seabeds that pose challenges for conventional jack up rigs.

Mat floating foundation.

A shallow foundation is a type of building foundation that transfers building loads to the earth very near to the surface rather than to a subsurface layer or a range of depths as does a deep foundation shallow foundations include spread footing foundations mat slab foundations slab on grade foundations pad foundations rubble trench foundations and earthbag foundations. A floating foundation is a type of foundation constructed by excavating the soil in such a way that the weight of structure built on the soil is nearly equal to the total weight of the soil excavated from the ground including the weight water in the soil before the construction of structure. A raft or mat foundation consists of a large concrete slab or a slab and beam system resting on soil or rock and supporting all the loads through a number of columns or walls. At those places we use mat foundations to distributes the whole loads of the structure to the soil when the area of the footing was increase than the soil load bearing capacity will also increase because this foundation reduces the stress on the soil at the same place.

Mat foundation also known as a raft foundation or floating foundation is a way of giving extra support to a building there are many reasons why mat foundation is chosen by builders across the globe. When the raft foundation is supported on piles it is called a piled raft. References in periodicals archive. Raft mat foundation is used in those places where we have less bearing capacity of the soil.

After that a structure is built on it. One reason is if the soil on which the building is constructed does not have a bearing capacity. A floating foundation is the foundation of a building that does not use footings. Depending on the total load applied to the mat and underlying foundation system the thickness of mat foundations can vary from 1 ft 0 3 m to more than 20 ft 7 m.

In case of floating foundation the weight of structure built on the soil is nearly equal to the total weight of the soil including water in. The reinforcing system in the mat can be quite substantial with heavy reinforcing bar mats in the bottom top or both locations within the mat depth. Raft or mat foundations a raft foundation also called a mat foundation is essentially a continuous slab resting on the soil that extends over the entire footprint of the building thereby supporting the building and transferring its weight to the ground.
