Pile sinking construction method based on jacking-pushing walking platform

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of pile sinking construction of steel pipe piles, in particular to a construction method for sinking piles based on a jacking walking platform. Background technique [0002] Steel pipe piles are important supporting components of structures such as bridge piers and port terminals. In order to maintain the stability of these buildings, steel pipe piles usually require good structural stability. The pile sinking construction of steel pipe piles needs to be carried out in accordance with strict design requirements Only in this way can we ensure that the steel pipe piles for sinking piles have good supporting performance. At present, there are usually two methods for pile sinking construction of steel pipe piles, one is pile sinking construction by piling ship, and the other is pile sinking construction based on floating walking platform. [0003] Piling ship construction is to use a special piling ship to carr...

Problems solved by technology

[0004] The construction method of the floating walking platform is to use the floating platform floating on the water as the support point of the pile sinking construction. The floating platform is anchored by anchor ropes, and the stability in the horizontal direction is very good, but there are the same problems as the piling ship construction. In the case of turbulent water waves, the vertical stability of the floating platform is not good, and the floating platform will fluctuate with the fluctuations of the water waves

In order to solve this problem, some platforms use auxiliary piles to fix the platform, which can solve the problem of poor platform stability, but the construction of auxiliary piles is time-consuming and labor-intensive, and the auxiliary piles need to be removed later, which greatly slows down the entire construction progress

[0005] To sum up, the prior art steel pipe pile sinking construction methods all have the problems of poor stability, high construction difficulty and potential safety hazards
