Bottom width 2.75m, Height 5.00m Side slope 1:1/4 Length of coconut pile 7.00m Spacing 0.75m No. of leyers 2 Length of full coconut pile required for 10m = ((10/0.75)+1)x2x7.00 = 200.67m Length of (1/4 split) coconut cross ties for 10m = 3x2.5 av. x 7 Nos. = 52.50 m Length of 1/4 split weiling pieces for 10m = 3x2x10 = 60m cost of full coconut post (Details vide 60.64.1), Coconut post required for 1m =200.67/10 = 20.06m (average length of coconut pile is 7 m and dia 25cm) Assuming cocunut post can be used 2 times No. of coconut pile required for 1m = 20.06/7 = 2.87 nos. Carriage of timber = 2.87x7x3.14x0.125x0.125 = 0.985cum Assume 3 rows wailing pieces in both sides and 3 cross ties, Total 52.60+60 - 112.50m Hence for 1.0m = 112.50/10 = 11.25m 7m long coconut tree equals 24m 1/4 split coconut piles , coconut post required = 11.25/24 = 0.469nos. Carriage required = 7x3.14x0.125x0.125 = 0.343cum Sawing area for 1m = 0.375x6x2x0.25 = 1.406sq.m Carpenter II class required = (4.3/10)x1.125 = 0.4838nos. Totla no.of coconut pile for 10m length @ 0.75m c/c = 10/0.75+1 = 14 nos on both sides = 14x2 = 28 nos. for 1m length = 28/10 = 2.8 nos Pile driving down length = 2.0m total length 2.0x2.8 = 5.6m Screening the frame with polythene sheet nailed to wailing pieces and coconut post, Plythene sheet require =10.3x2x5.00 = 103.00sqm For 1m = 103/10 = 10.30sqm Quantity of clay = (2.0+2.75)/2x5.00 = 11.88cum
