is very important to know what soil is made when a building. The same can be classified according to their size: 1) Gravel, 2) sand, 3) clays, 4) silt.
1) are those stony gravels from the progressive decomposition of rocks and its diameter is bounded between 0.2 cm and 1.5 cm. Can be obtained naturally or from chopped crushed rock in the quarry.
2) The sands are small grains that have more consistency in the depth, there is no bond between them and the charge is deformed instantaneously. Their size ranges from 0.02 mm to 2mm.
3) The limos are next in size between 0.02 mm and 0.002 mm and the excess water makes them ill to build as they have very little resistance to support.
4) The plates are small clay product of the disintegration of the soil. The presence of water causes small particles to adhere to each other which makes it by applying a force to slowly warp. As dimensions are talks of less than 0.0002 mm
The rock supports between 5-40kg/cm2, 4-8kg/cm2 gravels, sands and clays 3-5kg/cm2 0.5-3kg / cm2.
have to study the mechanical strength, the geological profile and the presence of water in soils that determine the settlement. Topsoil and waste landfills have no settlement is possible because organic matter and decompose.
foundations can be sorted according to different criteria:
1) By the way they transmit the loads to the ground
-
Direct - Indirect
- Mixed
2) Due to the depth where the soil is resistant
- Surface
- semideep
- Deep
3) For your disposal on the ground
- Spot
- Linear
- Slabs
will study the following foundations:
1) Given: foundations are punctual, isolated, direct, superficial and not very considerable size. They are used for flat surfaces in shallow water. Are buried in the ground (it makes a sediment and fill it with rocks and concrete) and they rely on the rafters, from which the pillars will rise.
2) Skate: A foundation point, semi-deep has the advantage that widens the base of the pillar as a better distribution of loads. Reinforced concrete are used as the stable ground is a bit is a little deeper in the previous case, between 4-5m.
3) Pilotis: specific foundations are deep, it makes a big hole and filled with concrete and iron. The walls of the holes are so irregular that friction contributes to the foundation. This type of foundation is used in soils with water.
4) Skate Run: This case is a linear surface foundation for land with stable soil no more than a meter. They are made of concrete like the shoe.
5) Stalls: These are shallow foundations, large slabs of concrete evenly distributed loads.
