Problems solved by technology

[0005] The shape of the cross section of the current friction pile is circular or rectangular, and the surface area of ​​the side of the pile is small, so that the frictional resistance between the side of the pile and the soil layer is relatively small, resulting in poor bearing capacity of the pile, so in the construction of the foundation In the process, a larger number of piles is required to increase the bearing capacity

Embodiment 1

[0056] Such as figure 1 As shown, the present embodiment provides a kind of concrete pile, and this concrete pile comprises:

[0057] The pile tip 1 and the pile body 2, the side projection of the pile tip 1 is conical, and one end of the pile body 2 is connected with the end surface of the pile tip 1;

[0058] The side projection of the pile body 2 is a rectangle, and the shape of the cross section of the pile body 2 is herringbone, such as figure 1 shown, and see figure 2 , the shape of the herringbone includes three convex arcs 3 and three concave arcs 4, and the two ends of each convex arc 3 are respectively connected with a concave arc 4 smoothly to form a herringbone. The shape of the end face of the tip 1 is herringbone;

[0059] The end face area of ​​the pile tip 1 is the same as the end face area of ​​the pile body 2 .

[0060]The present invention designs the cross-section of the concrete pile into a herringbone shape, so that the side surface area of ​​the con...

Embodiment 2

[0090] Such as Figure 6 As shown, the embodiment of the present invention provides a method for manufacturing the concrete pile described in the first embodiment. When the concrete pile described in the first embodiment is a prefabricated concrete pile, the method may include:

[0091] Step 101: install the pile formwork with a herringbone cross section, and the shape of the inner cavity of the pile formwork is the same as that of the concrete pile;

[0092] Step 102: pouring concrete into the pile form;

[0093] Step 103: maintaining the concrete in the pile form;

[0094] Step 104: Remove the pile form to obtain concrete piles.

[0095] The present invention designs the cross-section of the concrete pile into a herringbone shape, so that the side surface area of ​​the concrete pile is increased, the friction resistance between the pile side and the soil layer is increased, the bearing capacity of the pile is improved, and the process of foundation treatment is reduced. T...

Embodiment 3

[0106] Such as Figure 9 As shown, the embodiment of the present invention provides a method for manufacturing the concrete pile described in the first embodiment. When the concrete pile described in the first embodiment is a poured concrete pile, the method may include:

[0107] Step 201: sinking a pile form with a spud can with a herringbone cross section into the soil layer, the inner cavity of the spud can has the same shape as the pile point 1 of the concrete pile;

[0108] The spud boot can protect the pile point 1, and at the same time, the spud boot can compact the surrounding soil layer, thereby reinforcing the soil layer around the concrete pile.

[0109] Optionally, a pile form with a spud can and a herringbone cross section can be sunk into the soil layer by means of a vibrating pipe sinking machine.

[0110] Step 202: While pouring concrete into the pile formwork, formwork drafting is performed until the pile formwork is completely pulled out and the spud cans re...

Abstract

The invention discloses a concrete pile and a manufacturing method thereof, and belongs to the field of foundation design. The concrete pile comprises a pile tip and a pile body, wherein the side projection of the pile tip is conical, and one end of the pile body is connected to the end surface of the pile tip; the side projection of the pile body is rectangular, the cross section of the pile body is of a lambdoidal shape, the lambdoidal shape comprises three arc lines protruding outwards and three arc lines concaved inwards, and the two ends of each arc line protruding outwards are smoothly connected to the corresponding arc line concaved inwards for forming the lambdoidal shape; the end surface of the pile tip is of a lambdoidal shape, and the area of the end surface of the pile tip is equal to the area of the end surface of the pile body. According to the concrete pile and the manufacturing method thereof, the cross section of the concrete pile is designed to be of the lambdoidal shape, and therefore the superficial area of the side surface of the concrete pile is enlarged, the frictional resistance between the side surface of the concrete pile and the soil layer is increased, the bearing capacity of the pile is improved, the concrete consumption in the foundation treatment process is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of foundation design, in particular to a concrete pile and a manufacturing method thereof. Background technique [0002] Concrete piles are widely used in the current foundation treatment. Concrete piles can be sunk to a certain depth in the soil layer, and the bearing capacity is mainly provided by the friction between the side of the pile and the soil layer, and the load transmission on the upper part of the pile is spread to the surrounding of the pile. in the soil layer. [0003] The shape of the cross-section of the current concrete piles is mostly circular or rectangular. The concrete piles can be made on the production site and then sunk into the ground, or the holes can be drilled directly at the positions where the concrete piles need to be installed, and then concrete can be poured into the holes. Form concrete piles. [0004] In the process of realizing the present invention, the inventor finds that there...
