Abstract

The invention discloses a mechanically-connected prefabricated special-shaped pile, and relates to the technical field of concrete piles. The prefabricated special-shaped pile comprises a lower prefabricated pile, elastic inverted teeth and a locking piece, and further comprises a reinforcing mechanism for firm connection, a buffering mechanism for avoiding pile breakage and an installation structure facilitating rapid connection, wherein an upper prefabricated pile is installed above the lower prefabricated pile, an upper pre-embedded installation part is installed on the inner side of the upper prefabricated pile, and an upper prestressed steel bar is installed above the upper pre-embedded installation part. The locking piece is clamped into a lower pre-embedded installation part, when the locking piece moves downward, the lower pre-embedded installation part extrudes the locking piece, an elastic telescopic block is extruded and deforms, in the descending process of the locking piece, the second slope of a clamping block is matched with the first slope of a check block, the clamping block is enabled to smoothly move downwards to the position below the check block, then the elastic telescopic block resets to enable the clamping block to rebound and be clamped below the check block to be fixed, so that quick connection of the upper pre-embedded installation part and the lower pre-embedded installation part is realized, and the problem of complicated installation is solved.

Description

technical field [0001] The invention relates to the technical field of concrete piles, in particular to a mechanically connected prefabricated special-shaped pile. Background technique [0002] After nearly 30 years of development, the product specifications of my country's prefabricated piles are becoming more and more abundant, and the matching is more reasonable. In order to improve the bending performance of the pile body and enhance the ability to resist horizontal forces, a prefabricated pile New products emerge one after another, realizing the diversification of pile foundation materials and expanding the application range of pile foundation materials. The current mechanically connected piles are cumbersome to connect, and the connection is not firm, which may easily lead to falling off and poor safety. [0003] After searching, the Chinese patent authorization announcement number CN 213358595 U, announced on June 04, 2021, discloses a mechanical connection structure...
