More Information
Summary:The invention discloses a highway subgrade protection engineering reinforcing method which comprises the following steps: designing a construction drawing according to the condition of a subgrade, then carrying out on-site lofting, excavating a subgrade foundation pit, checking and accepting the foundation pit after the foundation pit is excavated, and pouring concrete on a bracket supporting wall supporting template. Transverse straining beam concrete is poured on the transverse straining beam supporting formwork, a C20 concrete bracket supporting wall is adopted on the outer side of the roadbed retaining wall, and the wall bodies are connected through C25 reinforced concrete transverse straining beams, so that the wall bodies are in a grid shape, and overall stress is achieved. According to bracket supporting and reinforcing, deformation and cracks of the existing retaining wall are resisted mainly through the dead weight of the bracket, it is ensured that damage of the existing retaining wall does not deve
