Bridge reinforcing foundation and construction method thereof
The invention relates to a bridge reinforcing foundation and a construction method thereof, and belongs to the technical field of bridge foundation maintenance. The bridge reinforcing foundation involves an existing bearing platform, a newly-added bearing platform located at the bottom of the existing bearing platform and a press grouting layer, wherein newly-added bearing platform steel bars arearranged in the newly-added bearing platform, and the press grouting layer is located between the existing bearing platform and the newly-added bearing platform so as to fill a gap between the existing bearing platform and the newly-added bearing platform. According to the bridge reinforcing foundation and the construction method thereof, the gap between the existing bearing platform and the newly-added bearing platform can be filled with the grouting layer, the existing bearing platform and the newly-added bearing platform can be effectively connected, a complete stress system is formed, thespace between the existing bearing platform and the newly-added bearing platform is filled with the grouting layer in a high-pressure injection mode by the press grouting layer, it is can be guaranteed that the uneven position of the bottom face of the existing bearing platform is densely filled without dead corners, the on-site construction process is simple, and construction is rapid.
本申请涉及一种桥梁加固基础及其施工方法，属于桥梁基础养护技术领域，桥梁加固基础包括：既有承台及位于既有承台底部的新增承台，新增承台内设有新增承台钢筋；压浆层，压浆层位于既有承台和新增承台之间，以填充既有承台和新增承台之间的空隙。本申请的桥梁加固基础及其施工方法能够通过压浆层填充既有承台和新增承台之间的间隙，能够将既有承台和新增承台有效连接，并形成完整的受力体系。压浆层通过高压注入的方式填充在既有承台和新增承台之间，可保证既有承台底面凹凸不平处填充密实、无死角，并且现场施工工艺简易，施工快捷。
