Vein-like tubular pile

A pipe pile and tendon-shaped technology, which is applied in the field of concrete pipe pile manufacturing, can solve the problems that the raised bamboo joints cannot form a strong support, the density of the upper soil cannot be increased, and the bearing pressure of the pipe pile cannot be increased. To achieve the effect of expanding the effective support area, reducing the cost of pile pressing, and reducing the difficulty of pile pressing

Problems solved by technology

Its shortcomings: the bamboo joints on the pile body are protruding. When piling, the protruding bamboo joints on the pile body can only press down the soil pressure forcibly, but cannot make the soil form a reverse upward movement, so The density of the upper soil around the pile body between the two bamboo nodes cannot be increased, and it cannot form a strong support for the raised bamboo nodes, and the purpose of increasing the bearing pressure of the pipe pile cannot be achieved

Embodiment 1

[0021] Embodiment 1: with reference to attached figure 1 with 2 . Spiral tendon-shaped pipe pile, which includes a pile body 1, a reinforcement rib 3 is arranged in the pile body 1, and there are 1 or 2 or more than 2 spiral raised ribs 2 on the outer wall of the pile body 1 and are connected with the The pipe pile 1 has an overall structure, and the spiral raised ribs 2 are arc-shaped, and any spiral raised ribs on the pile body 1 do not overlap each other from beginning to end. The pile body 1 is in the shape of a cylinder, a square column, a rhombic column, a rectangle, a polygon, or a convex-concave tongue-and-groove shape. The production of the spiral pipe piles is first made into a model by using the existing technology, and the production technology of the concrete pipe piles is the existing technology, which will not be described here.

Embodiment 2

[0022] Embodiment 2: with reference to attached figure 1 with 3 . On the basis of Embodiment 1, the spiral protruding rib 2 is arc-shaped.

Embodiment 3

[0023] Embodiment 3: with reference to attached figure 1 with 4 . On the basis of Embodiment 1, the helical protruding ribs 2 are in a convex-concave arc shape.

Abstract

The present invention involves a special concrete pipe pile for a construction basic project, which is the field of concrete pipe pile manufacturing.It includes the pile body, the pile body has enhanced tendons, and the outer wall of the pile body has vertical raised tendons.Advantages: The design of longitudinal tendons on the outer wall of the pipe pile not only effectively expands the effective support area of the overall pipe pile, improves the carrying capacity of the pipe pile, but also can effectively reduce the pressure of pipe pile pressure without changing the pressure of the pipe piles.The depth of the pile greatly reduces the difficulty of pile piles and the cost of pile pressure piles.

Description

Technical field: [0001] The invention relates to a special concrete pipe pile for building foundation engineering, which belongs to the field of concrete pipe pile manufacture. Background technique: [0002] The authorized announcement number is CN2611433Y, and the name is "pretensioned prestressed concrete special-shaped pipe pile". Large bamboo joints protrude, and the pile body between the bamboo joint protrusions is cylindrical. Its shortcomings: the bamboo joints on the pile body are protruding. When piling, the protruding bamboo joints on the pile body can only press down the soil pressure forcibly, but cannot make the soil form a reverse upward movement, so The density of the upper soil around the pile body between the two bamboo nodes cannot be increased, and the raised bamboo nodes cannot form a strong support, and the purpose of increasing the bearing pressure of the pipe pile cannot be achieved. Invention content: [0003] Design purpose: To avoid the deficien...
