Abstract

The invention discloses a pipe hammer system of a percussion drill for a rock-socketed inclined pile and an impact construction method of the rock-socketed inclined pile. By utilizing the pipe hammer system of the percussion drill, the hammer clamping is greatly reduced, and a hammer body has a guide effect, so that the high efficiency of a plum blossom percussion drill and the guidance quality of an abrasion drill are provided, the requirement of impact energy is met, and meanwhile, a formed hole is guaranteed to be the same as or be close to the axis of a pile casing; the consistency of the axis of the hammer body and the axis of a pile foundation is well guaranteed in a construction process, so that the hole forming quality is greatly improved; the hole forming speed is greatly increased through casting an integrally-formed cast steel hammerhead; in comparison with the existing construction method of the rock-socketed inclined pile, the construction method of the rock-socketed inclined pile, which is designed by the invention, has the advantages of simple operation and low construction cost, each pile machine only needs five operators, the construction method has better economic benefit, the hole forming time is shortened, and the hole forming efficiency and the hole forming quality are greatly improved.

Description

technical field [0001] The invention relates to the field of bridge and wharf construction equipment, in particular to a pipe hammer system for rock-socketed pile construction. [0002] The invention also relates to a construction method of rock-socketed piles suitable for projects such as docks and bridges, and is particularly suitable for the construction method of rock-socketed inclined piles. Background technique [0003] Drilling and rock-socketing construction of inclined piles of steel pipe piles is a pile foundation construction technology widely used in high-pile wharf engineering. High engineering. Existing rock-socketed piles mostly adopt plum-shaped percussion drill bits for construction, but this drill bit is not suitable for rock-socketed inclined piles. At present, the rock-socketing construction of inclined piles is mostly constructed by rotary drilling rigs, and the drill bits are roller cone bits. This hole-forming process has its limitations. The actual ...
