Roof Polystyrene EPS Rock Wool Wall Panel for Prefab House
Product description
The uneven settlement of the upper soil mass and the soil mass on both sides of the rigid structure buried under the embankment will often produce excessive additional pressure on the top of the structure. The vertical earth pressure coefficient can reach 1.2, or even 2.0 when the fill is high, that is, there is stress concentration on the top of the structure, resulting in cracking and destruction of the underground structure.
