Novel tree root structure pile and construction process thereof

Abstract

The invention discloses a novel tree root structure pile. The tree root structure pile is characterized by comprising a hollow column (1), wherein the upper end of the hollow column (1) is provided with a top cap (4), the lower end of the hollow column (1) is provided with a base (6), the side wall of the hollow column (1) is provided with a telescopic joint (2) communicated with the interior of the hollow column (1), and an expanding agent is filled in the hollow column (1). According to a construction process for the tree root structure pile, the telescopic joint extends outwards as tree roots in the construction process; and after the outward extension of the telescopic joint is completed, a filling material such as concrete and the like is poured so that the pile has higher strength and is completely stuck with the surrounding soil body. The pile of the type has reasonable structural design and wide application range; and on the premise that the length and the section area of the pile are not changed, the contact area between a pile foundation and a surrounding soil layer is obviously enlarged, so bearing capacity, friction resistance and stability of the pile are increased. Moreover, pulling resistance and sliding resistance of the pile are remarkably improved.

Description

technical field [0001] The invention relates to a concrete pile that can be widely used in various foundation loads such as construction engineering, bridge engineering, municipal engineering, and water conservancy engineering. Due to the weak bearing capacity of the foundation, there are requirements such as pull-out resistance and anti-skid resistance. Background technique [0002] Pile is an ancient craft, which has played an important role in the construction of ancient houses and bridges. As early as the Neolithic Age 7,000-8,000 years ago, in order to prevent the invasion of beasts, people once planted wooden piles in lakes and swamps to build platforms to build settlements. [0003] With the development of the times, in modern civil and water conservancy projects, piles still show strong vitality, and their types are also diverse. According to different pile materials, it can be divided into: wood pile, concrete mixing pile, steel pipe pile, steel sheet pile, reinfo...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art such as low pile bearing capacity, weak pullout resistance and anti-sliding ability, etc., and propose a new type of tree root structure with high bearing capacity, large frictional resistance and good stability The pile and its construction technology can be widely used in civil and water conservancy projects
