Highway subgrade protection engineering reinforcing method
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 develop any more, the roadbed protection capacity of the existing retaining wall is improved, and therefore the purpose of rapid reinforcing and repairing is achieved, and traffic interruption or potential traffic safety hazards are reduced to the maximum extent.
本发明公开了一种公路路基防护工程加固方法，包括以下步骤：按照路基情况进行施工图的设计，然后进行现场放样，进行路基基坑的开挖，基坑开挖后进行基坑验收，在牛腿支撑墙支模板上进行浇筑混凝土，在横系梁支模板上进行浇筑横系梁混凝土，在路基挡土墙外侧采用C20混凝土牛腿支撑墙，墙体间采用C25钢筋混凝土横系梁连接，使墙体形成网格状，整体受力。本发明牛腿支撑加固主要依靠牛腿的自重抵抗既有挡土墙变形、裂缝，确保既有挡土墙破损不再发展，提高既有挡土墙的路基防护能力，从而达到快速加固修复的目的，且最大程度减少交通中断或降低行车安全隐患。
