Abstract

The invention relates to the technical field of bridge engineering, in particular to a precast pile. The precast pile comprises a first pile foundation and a second pile foundation which are sequentially arranged in the vertical direction, an inserting piece is arranged at one end of the first pile foundation, a groove matched with the inserting piece is formed in one end of the second pile foundation, and the inserting piece extends into the groove so as to enable the first pile foundation and the second pile foundation to be connected. The provided precast pile has the beneficial effects that the on-site construction quality is easy to control, and the on-site construction time is easy to shorten.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a prefabricated pile. Background technique [0002] Pile construction methods are divided into two categories: prefabricated piles and cast-in-situ piles. The construction methods of prefabricated piles include: hammering method, vibration method, press-in method, etc. The selection of piling methods should not only be based on engineering geological conditions, but also consider the type, section, length, site environment and design requirements of the pile. Cast-in-situ piles are widely used in bridge engineering because of the advantages of no vibration, no soil compaction, low noise, and suitable for use in densely built urban areas during construction. [0003] However, cast-in-situ piles need to be tied with steel cages and cast-in-situ concrete on site. The construction quality is difficult to control and difficult to detect. The construction time on site is r...
