Shallow foundation and layout of communication tower
When the foundation soil on the surface of the communication tower construction site has good bearing capacity, the deformation of the foundation can also be controlled within an acceptable range, and the pulling force on the foundation can be shared by the foundation and the overlying soil, the shallow foundation form can be adopted.
Space truss towers usually have a foundation under each tower column. These independent foundations are connected by connecting beams to jointly bear the self-weight, bending moment and horizontal shear force uploaded from the tower.
In order to resist the uplifting force, the independent foundation under the column is an expanded reinforced concrete base plate, that is, a slab expansion base. The base plate can be round or rectangular with a certain thickness, and it is equipped with double-layer steel bars to withstand the reaction from the foundation. Bending moment and shear force caused by force.
