Protective structure suitable for existing bridge foundation and construction method
The invention discloses a protective structure suitable for an existing bridge foundation and a construction method. The protective structure suitable for the existing bridge foundation comprises a first protective structure and a second protective structure. The first protection structure comprises protection piles and a positioning frame, the positioning frame surrounds the side, close to a new bridge, of an existing bridge foundation and is fixed to an existing structure on the periphery of the new bridge, and the protection piles are arranged in a soil layer under the water surface of one side of the existing bridge foundation in a whipping mode along routing of the positioning frame. The second protection structure is a solid filling area, and the solid filling area surrounds the other side of the existing bridge foundation. The first protection structure is constructed on the side, close to the new bridge, of the existing bridge foundation, erosive wear of the existing bridge foundation caused by sand overturning caused by new bridge construction is reduced, the second protection structure is constructed on the other side, the stability of the first protection structure is guaranteed, meanwhile, damage to the other side of the existing bridge foundation caused by sand overturning can be prevented, and the service life of the existing bridge foundation is prolonged. Therefore, the construction device for protecting the existing bridge foundation in all directions is provided.
本发明公开了一种适用于既有桥梁基础防护结构及施工方法，适用于既有桥梁基础防护结构包括第一防护结构和第二防护结构；第一防护结构包括防护桩、定位架，定位架包围于既有桥梁基础靠近新桥的一侧，并固定于新桥外周既有的构筑物上，防护桩沿着定位架走线抽打安设于既有桥梁基础的一侧水面下土层内；第二防护结构为固体填充区域，固体填充区域包围于既有桥梁基础的另一侧。本申请通过在既有桥梁基础靠近新桥的一侧构筑第一防护结构，降低新桥施工造成的翻沙对既有桥梁基础的冲刷磨损，并在另一侧构筑第二防护结构，保证第一防护结构的稳固性，同时可防止翻沙对既有桥梁基础另一侧造成的损伤，从而提供了一种全方位防护既有桥梁基础的施工装置。
