Construction method for reducing differential settlement of foundation edge platform
The invention provides a construction method for reducing differential settlement of a foundation near-edge platform, which is characterized in that grouting pipes are horizontally buried in a backfill soil body of a temporary platform, the grouting pipes are buried in the backfill soil body in a layered and spaced manner, and an auxiliary grouting mode is adopted in a backfill area to improve soil texture, coagulate into a whole and increase strength and compactness; the temporary platform is of a trapezoidal structure, stress is balanced, and sedimentation is stable and synchronous; a settlement value is reserved, balance is gradually counteracted in the process of continuously increasing the load, and finally stable settlement is achieved and the level is kept; multiple modes are integrated, differential settlement is greatly reduced, and the comprehensive effect is remarkable; the method is simple in construction and convenient to operate, and can be expanded to the field of deep foundation pit reinforcement.
本发明提供一种减少基础临边平台不均匀沉降的施工方法，临时平台回填土体内水平埋设有注浆管，注浆管在回填土体中分层、间隔埋设，回填区采取辅助注浆方式改善土质，凝结形成整体，增加强度和密实度；临时平台设置为梯形结构，受力均衡，沉降稳定同步；采取预留沉降量值，在不断增加荷载过程中逐步抵消平衡，最终实现沉降稳定、保持水平；多重方式集成，大大减小不均匀沉降，综合效果显著；本发明施工简单、操作方便，可拓展到深基坑加固领域。
