7.8.Concreting of foundations
Concrete works quantity.
Concrete quantity in the foundations is determined by geometry formulas with the use of plan and foundation section drawn earlier
For the strip foundation:
𝑉𝑠/𝑓=(ℎ𝑓 (𝑠) ∙ 0,3 ∙ Р𝑏𝑎𝑠𝑒.) + (ℎ𝑓 (𝑏) ∙ 0,8 ∙ Р𝑓), 𝑚3
where, 𝑉𝑠/𝑓– volume of strip foundation, 𝑚3;
ℎ𝑓 (𝑏)– the height of the foundation
base, ref. monolithic strip foundation section;
ℎ𝑓 (𝑠)– the height of the structure basement, ref. monolithic strip foundation section;
Р𝑓 − total foundation length per the scheme (8 page).
For the columnar foundation:
𝑉𝑐/𝑓 = 𝑉𝑓 ∙ а, 𝑚3
𝑉𝑐/𝑓. – volume of all columnar foundations, 𝑚3;
𝑉𝑓– volume of concrete for 1
foundation, table 1, 𝑚3;
а– number of foundations in the plan (per the scheme).
