Plate load test (As per IS 1888).

Step-1

First survey the site area and selected a suitable location for test pit as decided by Engineer or mentioned in Drawing.


Step-2

Marked the area and clean or excavat

Step-3
Filled Sand bags for Loading arrangement as required for achieve the dead loadsion as required for locate to the foundation bed level or pcc bottom level.

Step-4
Prepared the dead load structure by using sand bags, ISB (We are used 300 & 250mm), shuttering plate or any other suitable methods as required to achieve ultimat load

Step-6
Place the base plate over a fine sand layer (5mm max thick) at center of the main ISM 300 (load carrying girder at center of stage) and centering by using plumb bob & spirit level.Step-7
After finish the plate installation adjustment hight are place above the plate carefully.Then hydrolic jack place properly that the load from bead transfer through jack to plate **If water come over plate or test location from ground then remove water by pumping
Step-8
Now applying the initial load and then applied 1st load, 2nd load, 3rd load .... Continue to ultimate load or failure occurred.

For each load increment settlements should be observed an interval of 1, 2.25, 4, 6.25, 9, 16, 25, 60 min.

Load increment stop If settlement rate more than 0.02 mm/min. and check settlement continue hourly.
Eatch load increment shall be kept for not less than 1 hours.

The test shall be continue till 25mm (50mm in special cases) or failure occurs.
