Background
The foundation is a member for bearing the load of the superstructure, and the bedding layer is a layer of granular material laid under the foundation for facilitating the construction of the foundation concrete and protecting the reinforcing bars of the foundation concrete. The flatness of the foundation and bedding construction significantly affects the positioning of the superstructure to the assembly accuracy. The precision of the formwork erection can be improved for cast-in-place construction, and is particularly important for prefabricated assembled concrete members which are being developed rapidly at present. The assembled components are generally required to be placed on a foundation, and along with the arrangement of the components, the position and the connection degree of each component are required to be controlled more strictly along with the increase of the size of the components, wherein the most fundamental precision control is the cushion layer and the foundation. The flatness or the design gradient of the cushion layer and the foundation needs to meet the requirement of engineering precision, and for the prefabricated construction method, the flatness of the cushion layer and the foundation generally needs to meet the requirement that the transverse flatness of the bottom plate is less than or equal to 0.5 percent of the width of the base, and the longitudinal flatness of the bottom plate seat does not exceed +/-3 mm per 2 m.
