Problems solved by technology

In the northern part of my country, there are bottom piles with a small top and a large bottom, but the depth of this kind of pile foundation is less than 10 meters, which is only suitable for small multi-storey buildings, and the amount of concrete pile structure is large, and the middle concrete pile structure is redundant. waste

Embodiment Construction

[0025] The drawings show the structure of the present invention and its embodiments, and the relevant details of the embodiments will be further described below in conjunction with the drawings. This kind of concrete pile structure is in the shape of a tree root, the trunk is a large pile body 1, and the root is a small pile body 2. The cross section of the large pile body 1 is petal-shaped, and the number of small pile bodies is equal to that of petal-shaped petals 3. Corresponding to the number, the centerline of the small pile forms an angle a relative to the centerline of the large pile. The length of the small pile is longer than the length of the large pile. The angle of the included angle can be adjusted according to the size of the upper load. The bottom of the pile body surrounded by the small pile body is provided with a cone-disk-shaped pile head 4 integrally connected with the pile body to replace the conventional reinforced concrete pile structure pile head. The botto...

Abstract

The invention discloses an invented concrete pile structure appearing in a tree root shape. The structure is characterized in that the pile looks like a tree root; the trunk is a big pile body (1); the tree root is a small pile body (2); the corss section of the big pile body (1) is in a petal shape; the number of the small pile bodies (2) corresponds with that of the petal-shaped leaf structure (3); the central line of the small pile body (2) is formed into an included angle ''a'' against that of the big pile body (1). The invention is characterized by high friction force against foundation earth; if executed throughout the country, the consumption of cement, sand, macadam and steel can be considerably lowered, so that large quantity of resources can be saved. Therefore, it is hoped to result in a revolution in architectural engineering execution.

Description

Technical field: [0001] The invention relates to an improved invention of a pile foundation, and specifically relates to an invention of a tree-rooted concrete pile structure. Background technique: [0002] In the prior art, the concrete pile structure is mostly straight pile, and its pile diameter is a uniform diameter. Therefore, in the soil with poor geological conditions, the diameter and length of the pile pipe and the number of piles must be required to achieve Therefore, it is a waste of manpower and material resources. So far, all construction projects and large-scale equipment foundations in the world have adopted pile foundations or large-excavated box foundations. Most coastal areas in China have adopted pile foundations. Foundation, and most of the piles are cylindrical, such as profiled steel piles, various on-site cast-in-place piles, reinforced concrete pile structure prefabricated piles, etc. In addition to ensuring the carrying capacity of upper buildings and lar...
