Is the calculation of brick foundation correct?

The correct calculation of brick foundation is that the foundation moistureproof layer should be considered in the quotation of brick foundation engineering.

Brick foundation is calculated by volume according to the size shown in the design. Among them, the foundation length: the outer wall is calculated according to the center line, and the inner wall is calculated according to the net long line. Deduct the volume of ground beam (ring beam) and constructional column.

The volume of overlapping parts of foundation T-joints, steel bars, ironware, pipes, foundation mortar moistureproof layer embedded in the foundation and individual holes with an area less than 0.3m2 shall not be deducted, but the overhangs of heating ditches against the wall shall not be increased, and the volume of widened parts of the foundation with battlements shall be incorporated into the basic quantities. Brick foundation engineering quotation should consider the foundation moistureproof layer.

Definition of brick foundation

Building foundation formed by brick as masonry material. It is the traditional masonry method of brick and wood structure in China. In modern times, it is often combined with concrete structures to build low-rise buildings such as houses, schools and offices. Common masonry methods are "two skins and one set" or "one skin and one set alternately". In order to ensure the integrity of the bottom layer, the "all-ding method" is adopted for the bottom layer laying.

Brick foundation mainly refers to the foundation made of sintered ordinary bricks and rubble, both of which belong to the category of rigid foundation. The foundation has the characteristics of good compressive performance, poor integrity, low tensile strength, bending strength and shear strength, easily available materials, simple construction operation and low cost. It is suitable for general civil buildings with solid and uniform foundation, small upper load, seven floors or less and light factory building foundation engineering with wall bearing.
