Bottom width 2.75m, Height 2.5m Side slope 1:1/4 Length of coconut pile 4.50m Spacing 0.75m No. of leyers 2 Length of full coconut pile required for 10m = ((10/0.75)+1)x2x4.5 = 126m 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 =126/10 = 12.6m (average length of coconut pile is 6 m and dia 25cm) Assuming cocunut post can be used 2 times No. of coconut pile required for 1m = 12.6/6 = 2.1 nos. Carriage of timber = 2.1x6x3.14x0.125x0.125 = 0.618cum 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 6m long coconut tree equals 24m 1/4 split coconut piles , coconut post required = 11.25/24 = 0.469nos. Carriage required = 6x3.14x0.125x0.125 = 0.294cum 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 =10.3x2x2.50 = 51.50sqm For 1m = 51.5/10 = 5.15sqm Quantity of clay = (2.0+2.75)/2x2.50 = 5.94cum
