Background Art Since the beginning of the new century, China's economy has developed rapidly, and the large- scale development trend of shipping ships in the world is obvious. With the rapid increase of port throughput in China, a large number of old wharfs are facing the problem of upgrading and renovation. In order to meet the needs of social and economic development and save coastal resources, upgrading and renovation of coastal port wharfs has become an inevitable requirement to ensure the safety of port operation, and also an inevitable way for port enterprises to take the path of sustainable development.
The common method ofwharf upgrading and reconstruction is to add pile foundation at the front edge of the berthing frame to improve its horizontal berthing force. At present, the construction methods of pile foundation mainly include water construction with the barge and the crawler crane and onshore construction with the crawler crane. Barge leasing is very expensive, beside a guide frame needs to be installed on the wharf for pile foundation positioning during the construction, and the construction procedure is complicated. Although the onshore construction with the crawler crane can save cost, due to the wharf is supported by the pile foundation under the bridge crane rail, the supports in other places are relatively weak. If the crawler crane runs in the position with weak support, the construction will pose a threat to the safety of the wharf structure.
CN 106120787 discloses 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.
CN 109208533 discloses a wharf integrated construction system based on the pile top pushing platform comprises the pile top pushing platform and a truss transportation system.
