[0035] The invention discloses a self-locking ground pile column integrated pipe, which can simplify the pile-making process and reduce the pile-making cost. The invention also discloses a construction method of the self-locking ground pile column integrated pipe.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by the terms "top", "bottom", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0038] The present invention discloses a self-locking ground pile column integrated pipe, comprising a pipe body 1, the top and bottom of which are both provided with openings. The pipe body 1 is characterized in that a ground pile pouring port 2 is provided on the pipe body 1. The ground pile pouring port 2 is used to connect the inner cavity of the pipe body 1 and the underground hole. The hole is pre-drilled before the pipe body 1 is installed. After the pipe body 1 is inserted into the hole, the ground pile pouring port 2 is located in the hole, or the ground pile pouring port 2 is lower than the hole edge of the hole. The ground pile pouring port 2 connects the inner cavity of the pipe body 1 and the hole, so the inner cavity of the pipe body 1, the inner cavity of the hole and the ground pile pouring port 2 form a communicating vessel structure. Cement is poured into the hole or the pipe body 1 until the cement surface in the hole and the cement surface in the pipe body 1 are both flush with the ground. After the cement is solidified, the pipe body 1 is automatically locked in the cement. Compared with the traditional pile forming method, the self-locking pile forming method in the present invention has a simple process and low pile forming cost.

[0039] The present invention provides that a plurality of ground pile pouring openings 2 are arranged along the axial direction of the pipe body 1, and a plurality of ground pile pouring openings 2 are arranged around the circumference of the pipe body 1. In this way, it is not only convenient for the inner cavity of the pipe body 1 to communicate with the hole during pile formation, but also can ensure that the portion of the pipe body 1 located in the hole is subjected to uniform locking force in the axial and circumferential directions.

[0040] The ground pile pouring port 2 may be a rectangular ground pile pouring port 2 or a ground pile pouring port 2 of other shapes. Preferably, the ground pile pouring port 2 is set as a round hole ground pile pouring port 2 or a waist hole ground pile pouring port 2. After curing, the stress on the cement at the round hole ground pile pouring port 2 or the waist hole ground pile pouring port 2 is more uniform.

[0041] In order to improve the pull-out resistance of the pipe body 1, the present invention provides reinforcing ribs 4 on the pipe body 1, and the reinforcing ribs 4 extend along the horizontal direction, or in other words, the radial direction of the pipe body 1. After pouring cement, the reinforcing ribs 4 are embedded in the cement between the pipe body 1 and the hole.

[0042] In order to ensure that the tube body 1 has a uniform and strong pull-out resistance, the present invention makes the following design: the reinforcing ribs 4 are arranged in pairs, and the two pairs of reinforcing ribs 4 are arranged symmetrically about the axis of the tube body 1. Multiple pairs of reinforcing ribs 4 are arranged along the axis of the tube body 1, and two adjacent pairs of reinforcing ribs 4 are arranged staggered in the circumferential direction. For example, when viewed from top to bottom, two adjacent pairs of reinforcing ribs 4 form a cross structure.

[0043] The above is the self-locking principle of the pipe body 1. Next, the ground pile column integration feature of the pipe body 1 is introduced: along the axial direction of the pipe body 1, the pipe body 1 is divided into a ground pile part 5 and a column part 6. The ground pile pouring port 2 is set on the ground pile part 5. The column part 6 extends above the ground.

[0044] In the prior art, the ground pile and the column are separate, and after the pile is formed, the column is connected to the ground pile by bundling, welding, etc. This not only makes the structure of the ground pile column complicated, but also reduces the construction efficiency.

[0045] In the present invention, the upright posts and the ground piles are integrated, thereby eliminating the connection portion between the ground piles and the upright posts, thereby simplifying the structure and improving the construction efficiency.

[0046] The column part 6 of the pipe body 1 is connected to other parts by means of constraints such as clamps, binding, bolt anchoring, etc. Therefore, the column part 6 of the pipe body 1 needs to have a higher bending resistance. To this end, the present invention makes the following design: a column pouring port 3 is provided on the column part 6 of the pipe body 1, and the column pouring port 3 is used to connect the inner cavity of the column part 6 of the pipe body 1 with the outside. After the pile is formed, the inner cavity of the ground pile part 5 of the pipe body 1 is filled with cement, and then cement is poured into the pipe body 1 through the column pouring port 3 to improve the bending resistance of the column part 6 of the pipe body 1.

[0047] In order to ensure that enough cement can be poured into the inner cavity of the column part 6 of the pipe body 1, the present invention stipulates that the column pouring port 3 is set close to the top of the pipe body 1. It should be noted that the cement grouting height of the column part 6 depends on the bending resistance requirements of the column part 6.

[0048] In the prior art, the material of the ground pile is usually steel, but in an operating environment with salinized soil and moist soil, the steel ground pile is easy to rust. In the present invention, the material of the pipe body 1 is preferably a fiber-reinforced resin-based composite material, and is processed into the pipe body 1 through a pultrusion process. The pipe body 1 made of a fiber-reinforced resin-based composite material has the advantages of light weight, high tensile strength, corrosion resistance, and non-conductivity.

[0049] Regarding the specific structure of the tube body 1, the tube body 1 can be a square tube, a rectangular tube, or a round tube. The structure of the tube body 1 is not specifically limited herein, and as long as the functions of self-locking and ground pile column integration can be achieved, it falls within the protection scope of this invention.

[0050] In summary, the self-locking ground pile column integrated pipe of the present invention has the following beneficial effects:

[0051] First, the ground pile part 5 is automatically locked in the cement of the hole, eliminating the need for a steel cage, improving construction efficiency and reducing pile costs;

[0052] Second, the ground pile part 5 and the column part 6 are formed on the integral tube body 1, eliminating the connection between the ground pile part 5 and the column part 6, improving the construction efficiency and simplifying the structure;

[0053] Third, the ground pile part 5 of the pipe body 1 is provided with reinforcing ribs 4, thereby improving the pull-out resistance of the ground pile part 5;

[0054] Fourth, cement is poured into the column part 6 of the pipe body 1, thereby improving the bending resistance of the column part 6;

[0055] Fifth: The tube body 1 is formed by pultrusion of a fiber-reinforced resin-based composite material, and the tube body 1 has the advantages of light weight, high tensile strength, corrosion resistance, and non-conductivity.

[0056] The present invention also discloses a construction method of a self-locking ground pile column integrated pipe, comprising the following steps:

[0057] S1: A hole with an inner diameter larger than the diameter of the pipe body 1 by a preset size is driven by a pile driver. The depth of the hole is also required, and the edge of the hole needs to be higher than the ground pile pouring port 2 on the top of the pipe body 1.

[0058] S2: Insert the tube body 1 into the hole.

[0059] S3: pouring cement so that the cement surface in the hole and the cement surface in the pipe body 1 are flush with the ground. After the cement solidifies, the ground pile part 5 of the pipe body 1 is automatically locked in the cement.

[0060] S4: pour cement into the column part 6 of the pipe body 1 through the column pouring port 3, so that the column part 6 has a higher bending strength.

[0061] The specific operation of step S3 includes three methods:

[0062] The first pouring method: pour cement from the top pile pouring port 2 into the pile part 5 of the pipe body 1 until the cement surface of the hole and the cement surface in the inner cavity of the pipe body 1 reach the top pile pouring port 2. Then pour cement into the hole or from the outside of the pipe body 1 so that the cement surface in the hole and the cement surface in the pipe body 1 are flush with the ground.

[0063] The second pouring method: pouring cement into the hole, or pouring cement from the outside of the pipe body 1, the cement will enter the inner cavity of the pile part 5 through the pile pouring port 2 until the cement surface in the hole and the cement surface in the pipe body 1 are flush with the ground.

[0064] The third pouring method: pour cement into the hole, and pour cement into the pipe body 1 through the top pile pouring port 2 until the cement surface in the hole and the cement surface in the pipe body 1 are flush with the ground.

[0065] Finally, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.
