Replacement and maintenance method of bridge foundation support padstone
The invention discloses a replacement and maintenance method of a bridge foundation support padstone, and belongs to the construction field of bridge engineering. The method comprises the steps of S2, firstly executing ascending operation on a main beam, then taking away the original foundation support, clearing the original foundation support padstone and the peripheral area, and ensuring the peripheral area to be clean so as to be convenient for the subsequent grouting operation; S2, arranging a steel hoop in the area of the original foundation support padstone, and ensuring the original foundation support padstone area is surrounded by the steel hoop to form a grouting space; S3, carrying out the grouting operation to the grouting space, solidifying the sizing agent by adopting the steel hoop as a template, and forming a novel foundation support padstone with the periphery being sleeved with the steel hoop, so that the replacement and maintenance of the original foundation support padstone is realized. By adopting the method, the original broken foundation support padstone does not need to be removed, the template does not need to be disassembled, and thoroughness in repairing is realized; moreover, the method is applicable to the situation for increasing the foundation support padstone, and the secondary damage of the novel foundation support padstone can be avoided.
