The invention discloses a bridge construction supporting method which is characterized by comprising the following steps: S1, pre-adjustment before supporting: a supporting device is moved to a position needing to be supported in advance, then a motor is started, and the motor drives a supporting seat to quickly ascend until the bottom of an inner cavity of the supporting seat is in contact with I-shaped steel at the bottom of a steel frame bridge; s2, fixing between the supporting device and the bridge: starting an air pump, quickly pumping out air in a cavity, keeping a vacuum state, quickly and tightly sucking the bottom of the inner cavity of the supporting seat and I-shaped steel at the bottom of the steel-framed bridge, then moving a reinforcing plate towards the inner side until the reinforcing plate is in contact with the I-shaped steel, and finally rotating a locking bolt to fix the supporting device and the bridge. The I-shaped steel is rotated and moved downwards under the assistance of the nut, so that the sliding seat is limited, and the I-shaped steel is secondarily fixed; s3, protection work is carried out; and S4, protecting the protection mechanism.
本发明公开一种桥梁施工支撑方法，其特征在于包括如下步骤：步骤S1、支撑前预调节：预先将支撑装置移动至需要支撑的位置，随后开启电机，该电机带动支撑座快速上升，直至支撑座内腔的底部与钢架桥底部的工字钢接触；步骤S2、支撑装置与桥梁之间固定：开启气泵，将空腔内的空气快速抽出，并保持真空状态，使支撑座内腔的底部与钢架桥底部的工字钢快速吸紧，随后向内侧移动加固板，直至加固板与工字钢接触，最后转动锁止螺栓，使其在螺母的辅助下旋转下移，对滑座限位，对工字钢进行二次固定；步骤S3、防护工作；步骤S4、对防护机构保护。
