Method for replacing bridge support
The invention discloses a replacement method of a bridge support. The replacement method comprises the following steps: S1, prefabricating a polyurethane support and a stiffening cover; s2, a jacking mechanism is adopted for jacking the bridge, and an original support is dismantled; s3, floating sand on the top of the padstone is removed, and after shoveling and flattening are conducted, a stiffening cover is installed on the top of the padstone; s4, a pre-embedded plate at the bottom of the bridge is cleaned, and an adhesive is smeared; s5, the top of the stiffening cover is smeared with a binder, the upper surface and the lower surface of the polyurethane support are evenly smeared with a curing agent, and the polyurethane support is placed between the stiffening cover and the embedded plate; and S6, the jack slowly returns oil, the bridge stably falls on the polyurethane support, and in this way, replacement of the bridge support can be completed. And S7, when the bridge support needs to be replaced again, heating is conducted to melt the adhesive, only the local bridge needs to be jacked, the polyurethane support is pulled out, and a new polyurethane supporting device needs to be replaced according to the mode. According to the replacement method, local jacking of the bridge can be achieved, replacement of the bridge support at the jacking part is completed, and the padstone cannot be damaged in the replacement process.
一种桥梁支座的更换方法，包括以下步骤：S1预制聚氨酯支座、加劲盖；S2采用顶升机构顶升桥梁，并拆除原支座；S3清除垫石顶部浮沙，铲除平整后，将加劲盖安装于垫石顶部；S4清理桥梁底部预埋板，并涂抹粘接剂；S5于加劲盖顶部涂抹粘结剂，并于聚氨酯支座上下表面均匀涂抹固化剂，并放于加劲盖与预埋板之间；S6千斤顶缓慢回油，桥梁平稳落于聚氨酯支座上，如此即可完成桥梁支座的更换；S7需要再次更换桥梁支座时，加热使粘结剂融化，仅需顶升局部桥梁，抽出聚氨酯支座，按照上述方式更换新的聚氨酯支承装置即可。该更换方法可实现桥梁局部顶升，完成顶升部位桥梁支座的更换，更换过程中，不会损坏垫石。
