CONSTRUCTION OF BOUNDARY WALL AT NGEL BILHAUR SOLAR PV PROJECT IN UTTAR

Pre-cast Boundary Wall

Pre-case Boundary wall with the total height of minimum 2850 mm above formation level (Finished ground level in case formation level is less than natural ground level). Upto height of 2000mm, it shall be constructed with pre-stressed precast reinforced cement concrete panels fixed to groves made in pre-stressed precast reinforced cement concrete column and over that for 600mm concertina coil with maximum loop spacing of 125mm. It shall be provided with Y-shaped MS angle. The pre-stressed precast reinforced cement concrete columns shall be provided at spacing not more than 2200mm c/c. The pre-stressed precast reinforced cement concrete columns foundation shall be minimum 1000mm below finished formation level. The boundary wall panels shall be at least 100m below formation level. The boundary wall columns of minimum size 200mmX150mm shall be provided with two grooves of minimum size 55mmX50mm, so as to receive boundary wall panels spanning from column to column with minimum width of 300mm and minimum thickness of 50mm as filler wall. The grade of concrete for all pre-stressed precast panels and column,etc shall be of minimum M30 grade and Grade of foundation block shall be min M25 grade conforming to IS 456. The size of the foundation shall be decided based on the site conditions however the minimum diameter of the foundation shall not be less than 350mm and depth less than1000mm. Total length of construction of boundary wall is lump sum 1.7 Kms
