The invention relates to the technical field of steel pipe pile sinking construction, in particular to a pile sinking construction method based on a jacking-pushing walking platform. A track beam is erected on a constructed a first round of steel pipe piles, then the walking platform is installed on the track beam, a crawler crane and a guide frame on the walking platform are adjusted, and a second round of steel pipe piles are inserted and piled through the crawler crane and the guide frame. A new track beam is erected to connecting all the second round of steel pipe piles, the jacking-pushing walking platform moves to the second round of steel pipe piles along the new track beam, the crawler crane and the guide frame are adjusted, inserting piling construction of a third round of steel pipe piles is completed through the crawler crane and the guide frame, and construction is conducted sequentially alternatively till construction of all steel pipe piles is completed. According to the pile sinking construction method based on the jacking-pushing walking platform, the structure is simple, and operation is convenient. The inserted-piled steel pipe piles are used as pile sinking foundations so that the stability of a pile sinking construction platform can be improved to a great extent, the accuracy of pile sinking construction is ensured, and the construction procedures are simpler.
