Geotextiles and geogrids are commonly used materials to stop the collapse of soil.

• Geotextiles are permeable fabrics made of synthetic fibers that are used to stabilize soil and prevent erosion.

• Geogrids are high-strength polymer grids that are used to reinforce soil and provide stability.

• Other materials such as gabions, retaining walls, and soil nails can also be used to prevent soil collapse.

• The choice of material depends on the type of soil, the slope angle, and the amount o...read more

To transfer TBM in Survey through Auto level, follow these steps:

• Set up the Auto level at a known point

• Measure the height of the Auto level

• Measure the height of the TBM

• Calculate the difference between the two heights

• Add or subtract the difference to the TBM height to get the correct elevation

• Repeat the process for all TBMs in the survey

A pile is a long cylindrical structure made of concrete, steel or wood that is driven into the ground to support a building or structure.

• Pile foundation is a type of deep foundation used to transfer the load of a structure to a deeper and stronger soil or rock layer.

• Piles can be made of concrete, steel, or wood and are driven into the ground using specialized equipment.

• Pile foundations are commonly used in areas with weak soil or where the structure is heavy and requires addi...read more

Pile foundation is provided to transfer the load of the structure to a deeper and stronger soil or rock layer.

• To support heavy structures on weak or compressible soil

• To resist lateral loads such as wind or earthquake

• To prevent settlement of the structure

• To reduce the effect of vibrations on the structure

• Examples: high-rise buildings, bridges, offshore structures

RL, FS, BS, HI are common surveying terms.

• RL stands for Reduced Level and is the vertical distance between a point and a datum.

• FS stands for Foresight and is the distance from the instrument to the point being surveyed.

• BS stands for Backsight and is the distance from the instrument to a point of known elevation.

• HI stands for Height of Instrument and is the elevation of the instrument above the datum.
