    Pile foundation and raft foundation is used for a high rise structure.

    Pile foundations are more capable of taking higher loads than spread footings.

     

    When allowable bearing pressure is low, the heavy structure is present & the site is with a highly compressible layer; then raft foundation is applicable.

    Thank You.

    When the height of member is less than 3times the least lateral dimensions of column it is termed as pedestal whereas when the value is greater than 3times least lateral dimension it is termed as column.

    For Pedestals (whose effective length is less than three times the least lateral dimension) the minimum reinforcement is specified as 0.15 percent cross sectional area of concrete.

    Difference between Black Water and greywater:

    Black Water:

    • Blackwater is the best water from bathrooms and toilets that contains faecal matter and urine.
    • Waterproof kitchens and dishwashers are also considered Black Water due to the contamination of pathogens.
    • It is also referred to as she waits for groundwater and can carry diseases and bacteria both of which could be harmful.

    Treatment of blackwater:

    • The biological or chemical treatment and infection are required for treating Black Water.

    Greywater:

    • Greywater is the best water that comes from sinks, washing machines, bathtubs and showers.
    • Greywater contains a very low level of contamination and making it easier to treat and process.
    • Recycled greywater is commonly used in irrigation and constructed wetlands as long as no harmful chemicals are present.

    Treatment of Greywater

    • Greywater can be reused in cartoons with little or no treatment subsurface irrigation system to evenly spread water around in the garden.
    • This method is very safe for treated greywater.

    Thank you.

    Factors affecting the selection of foundation:

    Factors affecting the selection of foundation based on politics to basic criteria:

    1. Based on soil condition
    2. Based on loads from the building

    1. based on soil condition:

    • The shallow foundations are most preferred Foundation whenever the soil close to the surface which is capable of support structural loads.
    • Where ground close to the surface is not capable of supporting structural loads Din hard starter is used for the foundation is required.
    • The stable ground requires Shallow Foundation whereas filled up Grounds has low bearing capacity thus requires deep Foundation.

    2. based on loads from the building:

    • In case of very low height building in a larger area than the extent of loading is relatively very slow and that’s why Shallow Foundation con resists the load from the structures.
    • In the case of high rise building with less area and high amount of loads. In that case, the foundation is required. Because the shallow Foundation may not be able to resist such high loads of great intensity.

    Thank you.

    universal foundation is pile foundation.

    it is used at all location, so we call it universal foundation in simple way

    basically pile foundation use at

    • where bearing capacity of soil is low
    • where chances of differential settlement of foundation
    • where structural load is very high like bridge or skyskiper building
    • where black cotton soil is present
    • where bearing strata depth is very high
    • where structure need to resist excessive vibration (wind mill)
    • pile foundation we can use every where.

    Jet grouting process:

    Jet grouting was first introduced by Pilots terraces S.A. in the year 2010 and in 2011, the first project using jet columns was constructed.

    Applications:

    • Soil capacity improvement
    • Settlement control
    • Reduction of soil permeability
    • Other environmental applications
    • Underpinning existing Foundation
    • Ground improvement
    • Lateral support excavations
    • Hydraulic barriers
    • Slope stabilization
    • Liquefaction control

    The treat grouting is one of the most demanding soil improvement technique and requires excellence in designing and execution engineers and involved specialist.

    The field test allows selecting the most effective execution parameters and verifies that the final product with its design properties.

    – When a building has a very heavy, concentrated loads, such as in a high rise structure, bridge or water tank.
