A steel pile shoe with high bearing capacity

Abstract

The invention discloses a steel pile shoe with high bearing capacity. The steel pile shoe is arranged at the front end of the pipe pile and includes a steel pile shoe body. The steel pile shoe body is composed of two hollow cylinders with different diameters. , including a small-diameter first steel spud shoe and a large-diameter second steel spud shoe, the first steel spud shoe is arranged on the upper end of the second steel spud shoe, and the side of the first steel spud shoe The wall is provided with a grouting channel; the diameter of the second section of the steel pile can is 8-10 cm larger than that of the first section of the steel pile can, and its diameter is equal to the diameter of the pipe pile. The steel spud shoe also includes a grouting pocket and a grouting pipeline; the grouting pocket is arranged on the periphery of the first section of the steel spud can, and its two ends are fixedly connected with the first section of the steel spud can; The grouting pipe is connected to the grouting bladder. The pipe pile steel pile shoe of the invention can greatly improve the bearing capacity of the pipe pile.

Description

technical field [0001] The invention belongs to the field of building material design, and in particular relates to a high-bearing-capacity pipe pile steel pile shoe. Background technique [0002] Generally, when the shallow foundation of the building site is relatively weak and cannot meet the requirements of the building for the bearing capacity of the foundation, and it is not suitable to take artificial foundation reinforcement measures, or when it is uneconomical to use artificial foundation reinforcement, the pile foundation is considered. Pile boots are a type of pile tip, made of steel plate, welded to the front end of the construction pipe pile, installed on the pipe pile head when the pipe pile is sinking, and play a guiding and sealing role. [0003] Pile static pressure construction is a pile sinking process that uses a static pile driver to press piles into the soil. Static pressure construction has the characteristics of no noise, no vibration, no impact force,...

AI Technical Summary

Problems solved by technology

[0003] Pile static pressure construction is a pile sinking process that uses a static pile driver to press piles into the soil. Static pressure construction has the characteristics of no noise, no vibration, no impact force, and the factory production quality of piles is relatively intuitive. However, at present In the production process, the steel pile shoe used is a steel pipe with the same diameter as the inner diameter of the pipe pile, and the bearing capacity of the steel pile shoe is limited
