Hydraulic ram pumps and Sling Pumps

Table 7: Schedule of material consumptionIf the most suitable place chosen is on sloping ground, you first have to level this area. Dig out anarea which is between 1.00 and 1.50 m larger than the diameter of the foundation slab. Make surethe area is really on level ground. Before digging the tank foundation, save the sloping ground fromsliding (see Fig. 5.3).figure 5.3This can be done by stepping the slope behind the proposed tank. The raiser can be made out ofwooden poles rammed into the ground and horizontally saved by either round poles or boards fixedto the rammed poles. The wood should be treated. The cheapest way is to dip it in old engine oil anddry it in the sun before use. The steps should not be filled up with soil but with solid material likesmall rocks, bricks and similar objects. This is the place where leftover material like cement mortarshould be poured in later. The soil above the steps should be saved by planting bushes. Proceedwith the foundation as described. If the ground is rocky, remove the soil between the different rocksas much as possible, together with loose rocks. Fill up the gaps between the rocks with lean-mixedconcrete, cover the area with empty cement bags and water them for at least three days, keepingthe bags constantly wet.32
