Reinforcing treatment method for scoured and emptied foundation of expanded foundation bridge
The invention provides a reinforcement treatment method for scoured emptying of an enlarged foundation bridge foundation, which comprises the following steps: step 1, measuring the area of a void area at the bottom of a bridge enlarged foundation, evaluating the stability of the bridge enlarged foundation, filling a mixture into the void area, and filling the void area until the void area is dense; step 2, pouring an embankment layer on the periphery of the bridge enlarged foundation, wherein a mud jacking pipe inserted into the void area and a vent hole communicated with the void area are pre-buried in the embankment layer; and 3, curtain grouting is conducted on the foundation around the bridge enlarged foundation, and reinforcement grouting is conducted on the lower foundation corresponding to the bridge enlarged foundation. The bearing capacity and the scouring resistance of the bridge expansion foundation can be greatly enhanced, it can be guaranteed that the bridge expansion foundation is in a long-term stable bearing state, the potential safety hazard that the bridge expansion foundation is disengaged is avoided, regular frequent maintenance of the bridge expansion foundation is not needed, the problem of bridge foundation disengagement is completely eradicated at a time, and the construction efficiency is improved. Manpower, material resources and financial resources are saved, and the cost investment is reduced.
本发明提供一种扩大基础桥梁基础遭冲刷掏空的加固处理方法，包括:步骤1，测量桥梁扩大基础底部脱空区的面积，评估桥梁扩大基础的稳定性，并向脱空区内填充混合料，填充脱空区至密实；步骤2，在桥梁扩大基础的外围浇筑护砌层，护砌层中预埋有插入脱空区的压浆管和连通脱空区的通气孔；步骤3，对桥梁扩大基础周围地基进行帷幕注浆，对桥梁扩大基础对应的下方地基进行加固注浆。本发明能够极大的增强桥梁扩大基础的承载能力和抵抗冲刷的能力，并且能够保证桥梁扩大基础处于长期的稳定承载状态，避免出现桥梁扩大基础脱空的安全隐患，无需对桥梁扩大基础定期频繁的维护，一次性杜绝桥梁基础脱空的问题，节约了人力、物力和财力，降低成本的投入。
