Problems solved by technology

[0002] Prefabricated prestressed pipe piles are used in large quantities in foundation engineering, but conventional prefabricated prestressed pipe piles have very smooth side walls, low friction with rock and soil, and low bearing capacity of foundation piles. Bearing capacity, but the consequence of this is to increase the cost

Abstract

The invention provides a novel prefabricated threaded tubular pile and a construction method thereof, and relates to the technical field of buildings. The novel prefabricated threaded tubular pile comprises a tubular pile body and a threaded on the outer side of the prefabricated threaded tubular pile body. The width of the thread ranges from 2 cm to 30 cm, and the thickness of the thread ranges from 2 cm to 6 cm. The thread space ranges from 10 cm to 80 cm, and the spiral included between the thread and the horizontal plane ranges from 10 degrees to 40 degrees. During construction, the prefabricated threaded tubular pile is transported to the site section by section, piling is carried out after positioning, the pile sections are connected in a welding manner, and finally a welding connection opening is reserved at the pile head. Due to the fact that the side thread is designed, the rigidity of a foundation pile is improved, and the bending resisting and shear resisting capacity of the foundation pile is improved. During construction, a thread drilling construction manner is adopted, drilling resistance is reduced, the drilling speed is increased, and the construction efficiency is improved. Under the same geological conditions, the bearing force of the foundation pile is improved, the design pile length is reduced, and the project cost is reduced.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a novel prefabricated threaded pipe pile and a construction method thereof. Background technique [0002] Prefabricated prestressed pipe piles are used in large quantities in foundation engineering, but conventional prefabricated prestressed pipe piles have very smooth side walls, low friction with rock and soil, and low bearing capacity of foundation piles. Bearing capacity, but the consequence of this is to increase the cost. How to find a new prefabricated concrete pile structure has become the key technology of concrete pipe piles. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the invention provides a novel prefabricated threaded pipe pile and its construction method, which increases the friction between the pipe pile and rock and soil, and enhances the bearing capacity. [0005] (2) Technical ...
