Tubular pile for wharf construction and pile foundation structure

Abstract

The invention provides a tubular pile for wharf construction. The protective device of the tubular pile comprises a first protective cover and a second protective cover. The first protective cover includes a first cover portion and a second cover portion. The first cover part and the second cover part are respectively arranged near two sides of the first lock catch. The first cover part and the second cover part extend from the top end to the bottom end of the first lock catch in the longitudinal axis direction of the pipe pile body. The first cover part, the second cover part and the pipe wall define a space used for containing the first lock catch and the second lock catch which are clamped. The first free end of the first cover part and the second free end of the second cover part are both opposite to the end face, away from the pipe wall, of the first lock catch. The second protective cover is arranged close to the bottom end of the first lock catch. An opening structure is defined by the pipe wall, the bottom wall of the second protective cover and the at least one side wall pipe wall. An opening structure surrounds the bottom end of the first lock catch and the bottom end of the first protective cover.

Description

technical field [0001] The present disclosure generally relates to the technical field of wharf pile foundation construction, and in particular relates to a pipe pile for wharf construction and a pile foundation structure for wharf construction. Background technique [0002] So far, the wharf structure mainly includes the following three categories: gravity structure, high pile cap structure and sheet pile structure. Among them, the advantages of sheet pile structure are simple structure, less material consumption and low cost. Compared with the gravity structure, the sheet pile structure has lower requirements on the foundation conditions. Compared with the high-pile-capped structure, the sheet pile structure is more adaptable to local overloading, and in the construction process, the sheet piles can be driven first and then the excavation of the harbour in front of the wall can be carried out, which can greatly reduce the amount of excavation and filling.

AI Technical Summary

Problems solved by technology

However, in the process of driving the pipe pile into the foundation, it is inevitable that sand or other debris will enter the lock of the pipe pile lock, thereby causing the lock to be blocked.

In particular, in the construction of deep-water wharves, the geology of the piles at the front of the wharf is relatively complex, which is more likely to cause dense sand to enter the lock

The blockage of the lock of the pipe pile lock or the entry of dense sand will affect the driving of the sheet pile and the quality of the occlusal connection of the lock, and may also cause the lock to tear during the construction of the sheet pile, resulting in Sand leakage
