What are the procedure of construction of a well foundation?

Answer 1

depending on loads and soil condition a pile type may chosen as suitable for certain conditions. 1.determine ground conditions. 2.determine loads requirement . 3.decide on the pile type. 4.in some cases access may restrict you pile choice. 5.loads cases will be considered 6.pile type,concrete strength,typy of reinforcement. 7.instollation of piles.

Answer 2

A pile is more slender than a pier. They are essentially the same thing. The cut off diameter or cross section size for when a pile becomes a pier is unknown. but the pile is far better tha pier because the total masss is divided equally between each pile used in pilefoundation and the foundation is very much stable.

Answer 3

Construction of well foundation

Work is done during non-monsoon months of the year

Islolate the area by making bund around it so that river water flows
beyond the island. Sheet piling is also resorted where bed is
deep

Low height Sand island is created as platform over which cutting edge of steel
for well curb is placed and well curb is cast with some steining height
(may be 1.5 to 3.0m)

Kentelage (load ) is applied through platform at top of steining, cast so far,
to sink the steining and simultaneously dredging of material from inside is resorted.

Keep Casting steining and applying kentelage to sink it.A minium 48 Hrs curing time
is must for steining after its casting for it to be ready for sinking.

Initially the sinking will be faster and inside dredging is easy due to soft top strata
Once steining get sunk deeper, there is enough friction from sides.Dredging from inside will
need effort for sinking it ( before loading it) thru trained divers(with oxygen mask) who go
below and dredge at bottom of steining since river water seeps into well

The process goes on for one or more seasons depending upon depth of sinking.
The sinking process is slow and time taking.Half constructed wells
have to see the flash floods of river when islands and bunds wash away
during monsoon.

Once final level is achieved, well is plugged at bottom with rich concrete as per
drg and specifications.This is bottom plug.

Well upto nearly mid-height is filled with sand(or excavated material free
from organic matter) and again plugged with rich concrete
acting as intermediate plug.

From intermediate plug upto well cap soffit level , the well is filled with
sand/exc material and well cap is cast

Answer 4

Pile foundation can be used in low soil bearing capacity in order to minimize the total deflection of the building.

Answer 5

Depending on the soil, height, weight & size of building. All bridges are put in by friction or to bed rock.

Answer 6

pile foundation is super structure load in the building transfer to the suitable dipper sub soil or rock
