What is the meaning of the template bearing surface elevation in the bridge specification?
Elevation refers to the distance from a point along the vertical line to the absolute base plane, said the absolute elevation, referred to as the elevation. The distance from a point along a vertical line to a hypothetical quasi-base surface is assumed to be an elevation.
There is a pre-camber or pre-elevation between the bridge base elevation and the design elevation, since the template is not stressed before the concrete is poured,
The template completes the elevation of the surface. The template completes the elevation of the surface.
Elevation indicates the height of each part of the building, which is the vertical height of a certain part of the building relative to the reference plane (zero point of the elevation). In the construction drawing there is often a small right-angled isosceles triangle, the tip of the triangle or the up or down, which is the sign of the elevation.
