[0002] At present, underwater construction mostly requires the construction of steel trestles to serve as a passage for personnel, work platforms, and transportation equipment such as cranes. Before the construction of the steel trestles, it is generally necessary to build an auxiliary platform on the shore as a starting platform for the construction of the steel trestles. The existing auxiliary platform is directly used as a starting platform for construction after clay filling and compaction. However, during the construction of the steel trestles, a crane is required to cooperate with a vibrating hammer to stand on the auxiliary platform to construct the steel pipe column, and the tonnage is large. The stability of the filling area cannot be guaranteed, and the safety is low. In response to the above problems, the present application provides a structure for erecting an auxiliary platform in the approach bridge area to ensure the stability of the embankment filling area.
