Roadbed reinforcement stiffness and its construction methods

摘要

The present invention prevents cracking of a rigid wall made of a precast concrete panel, provides a vertical view of the soil, allows installation of an anti-flow barrier, sprays gravel, facilitates leveling of the twisting phenomenon that occurs during precast concrete panel construction. An object of the present invention is to provide a rigid reinforced roadbed which is installed after assembling a precast concrete panel to minimize an area occupied by a turnbuckle due to a trowel load and to prevent warpage and a construction method thereof. The rigid reinforcing bed panel according to the present invention comprises a reference frame, a flow preventive film, a buried layer, a precast concrete panel, a turnbuckle, a site concrete.
