Figure 1 The figure shows a traditional river bank protection structure, which includes a front row of piles 10, a rear row of piles 20, a retaining wall bottom plate 30 and a retaining wall body 40. In order to meet the requirements of its own stability, this retaining wall structure usually sets a retaining wall bottom plate 30 of a certain width behind the retaining wall body 40. In order to avoid the retaining wall bottom plate 30, the pile foundation 51 of the newly built building 50 along the river often needs to retreat a certain distance, resulting in the building 50 being unable to be built near the river, poor hydrophilicity, and occupying a large area.
