[0034] The embodiment of the present invention discloses an integrated pile column, referring to Figure 1 , which shows a schematic diagram of the structure of an integrated pile column provided in an embodiment of the present application, the integrated pile column comprises a precast concrete pile body 10, a steel structure body 11 and a first steel member 12, one end of the first steel member 12 is located in the precast concrete pile body 10, and the other end of the first steel member 12 is located in the steel structure body 11; further refer to Figure 4 As shown, part of the precast concrete pile body 10 and the steel structure body 11 are placed in the hole 18 , and concrete 21 is poured in the hole 18 so that part of the precast concrete pile body 10 and the steel structure body 11 are connected to the concrete 21 .

[0035] The precast concrete pile body 10 is a component made of steel-concrete in a precast manner. Steel-concrete is a building material that combines steel bars and concrete, also known as rigid concrete or rigid steel concrete. Steel-concrete has the advantages of high strength, small cross-sectional dimensions, strong bond strength with concrete, saving concrete, increasing usable space, reducing project costs, and improving project quality; this makes the precast concrete pile body 10 of the embodiment of the present application also have the above advantages of steel-concrete.

[0036] The steel structure body 11 is a component formed by combining and connecting steel materials, and can be connected by bolt connection, weld connection, rivet connection, etc. The steel structure body 11 has a light weight, is easy to construct, and can reduce the weight of the integrated pile column and the difficulty of constructing the integrated pile column.

[0039] When the integrated pile column of the embodiment of the present application is used, part of the precast concrete pile body 10 and the entire steel structure body 11 are placed in the hole 18, and concrete 21 is poured in the hole 18 so that the concrete 21 wraps part of the precast concrete pile body 10 and the steel structure body 11. The integrated pile column has fewer parts to be constructed on site, which can reduce the construction period on site and the construction cost, making the integrated pile column suitable for use in a variety of projects, for example, the integrated pile column is suitable for use in photovoltaic power generation projects.

It is understandable that the embodiment of the present application does not specifically limit the shape of the cross section of the precast concrete pile body 10, as long as it meets the use requirements. Figure 3 , which shows a schematic structural diagram of a rectangular cross section of a precast concrete pile body 10 .

[0041] Optionally, in order to reduce the weight of the precast concrete pile body 10, and to reduce the material while ensuring the strength of the precast concrete pile body 10, and to further reduce the cost of the precast concrete pile body 10, a center hole 22 is also provided on the precast concrete pile body 10. One end of the center hole 22 is located at the upper end of the precast concrete pile body 10, and the depth of the center hole 22 can be set according to the use requirements. For example, the other end of the center hole 22 extends to the lower end of the precast concrete pile body 10; for another example, the other end of the center hole 22 is located in the middle of the precast concrete pile body 10. Among them, the upper end of the precast concrete pile body 10 is the end of the precast concrete pile body 10 located on the upper side when the integrated pile column is under construction; the lower end of the precast concrete pile body 10 is the end of the precast concrete pile body 10 located on the lower side when the integrated pile column is under construction.

[0043] It is understandable that the number of the center holes 22 can also be set according to the use requirements, and the present application does not specifically limit the number of the center holes 22. For example, the center holes 22 are provided with two, three, etc. Figure 3 , which shows a structural schematic diagram of a precast concrete pile body 10 having a central hole 22 .

At the same time, the upper end plate 14 can be used for welding, providing a welding interface to facilitate welding of the integrated pile column with structures such as photovoltaic brackets.

[0047] It is understandable that the embodiment of the present application does not specifically limit the material of the upper end plate 14. For example, the upper end plate 14 is a steel plate, and when the upper end plate 14 is a steel plate, it has the advantage of simple and convenient welding.

The lower end plate 15 can protect the lower end of the precast concrete pile body 10 and prevent the lower end of the precast concrete pile body 10 from being damaged by collision or the like.

[0050] It is understandable that the embodiment of the present application does not specifically limit the material of the lower end plate 15. For example, the lower end plate 15 is a steel plate, and when the lower end plate 15 is a steel plate, the lower end plate 15 can be welded to the first steel member 12, thereby increasing the structural strength of the integrated pile column.

[0051] Optionally, the first steel member 12 is at least one of section steel, angle steel, channel steel and I-beam, which can be selected according to usage requirements.

[0053] Optionally, the upper end plate 14 is connected to the first steel member 12 to increase the structural strength of the precast concrete pile body 10. Figure 1 As shown, the upper end of the first steel member 12 extends to the upper end of the precast concrete pile body 10, and the lower end of the first steel member 12 extends out of the lower end of the precast concrete pile body 10. The first steel member 12 penetrates the precast concrete pile body 10, which can effectively improve the structural strength and bending resistance of the precast concrete pile body 10.

[0054] It is understandable that the embodiment of the present application does not specifically limit the number of the first steel members 12, and the first steel members 12 may be provided with one, two, three, etc., as long as the structural strength and bending resistance requirements of the precast concrete pile body 10 are met.

[0055] Optionally, the precast concrete pile body 10 further includes round steel 13, which is arranged parallel to and spaced from the first steel member 12. The round steel 13 can increase the structural strength of the precast concrete pile body 10 and improve the bending resistance of the precast concrete pile body 10. The round steel 13 can be prestressed round steel.

[0056] The first steel member 12 and the round steel 13 are symmetrically arranged in the precast concrete pile body 10, so that the precast concrete pile body 10 has strong bending resistance all around. Figure 3 As shown, the cross section of the precast concrete pile body 10 is square, and four first steel members 12 are provided, and the four first steel members 12 are arranged one by one at the four corners of the precast concrete pile body 10.

The steel structure body 11 is located in the concrete 21 of the hole 18, and the steel structure body 11 is wrapped by the concrete 21 as the skeleton of the cast-in-place concrete foundation. The steel structure body 11 is not exposed to the air and is not easily corroded; moreover, after the steel structure body 11 is connected with the concrete 21, it also has the advantage of high structural strength.

[0063] In the embodiment of the present application, the integrated pile column includes a connector 16, which is a pre-buried structural member. The connector 16 has two parts, wherein a portion of the connector 16 is located in the precast concrete pile body 10, and the remaining portion of the connector 16 extends out of the precast concrete pile body 10. One end of the connector 16 located in the precast concrete pile body 10 is connected to the first steel member 12, and the other end of the connector 16 extends out of the precast concrete pile body 10 and is connected to the auxiliary component group. The connector 16 can be connected to the auxiliary component group. The auxiliary component group is used to maintain the distance between multiple precast concrete pile bodies 10, or the auxiliary component group is used to keep the precast concrete pile body 10 vertically installed, so that the integrated pile column meets the requirements for construction accuracy.

[0064] Here, a plurality of means at least two. For example, a plurality of precast concrete pile bodies 10 means two, three, four, etc. precast concrete pile bodies 10.

[0065] Optionally, the connecting member 16 is at least one of an ear plate, a flat plate, a pre-embedded screw, and a U-shaped plate. It is understandable that in actual applications, a corresponding connecting member 16 can be selected according to the use requirements to be used for connecting with the auxiliary component group. Figure 1 , which shows a schematic diagram of the structure in which the connecting member 16 is a lug plate in the embodiment of the present application. The lug plate is provided with mounting holes, and the auxiliary member group is connected to the lug plate by fasteners such as bolts.

[0066] Optionally, the auxiliary component group is a scissor column support 19, refer to Figure 8 As shown, the scissor column brace 19 is used to maintain the distance between multiple precast concrete pile bodies 10. The scissor column brace 19 is an oblique support between two precast concrete pile bodies 10, similar to the X-shaped rod of scissors. The scissor column brace 19 can be used to maintain the distance between the two precast concrete pile bodies 10 accurately and control the accuracy of the column spacing size. When there are multiple precast concrete pile bodies 10, multiple scissor column braces 19 are correspondingly set to maintain the distance between the multiple precast concrete pile bodies 10.

[0067] Optionally, in practical applications, other supporting, pulling and other structures that can achieve dimensional precision control of column spacing can also be used to connect the two precast concrete pile bodies 10 .

[0068] Optionally, the scissors column brace 19 is at least one of slender rods such as angle steel, round tube, square tube, etc., which can be connected to the connecting piece 16 and can be used.

[0069] Optionally, the auxiliary component group is an auxiliary bracket 20, see Figure 5 and Figure 6 As shown, one end of the auxiliary bracket 20 is connected to the connecting piece 16, and the other end of the auxiliary bracket 20 is used to be inserted into the ground; the auxiliary bracket 20 is used to keep the precast concrete pile body 10 installed vertically, meeting the vertical installation requirements of the integrated pile column. After the integrated pile column is installed, the auxiliary bracket 20 can be removed, see Figure 7 , which shows a schematic structural diagram of the integrated pile column after the auxiliary support 20 is removed after installation.

[0070] In a specific embodiment of the present application, the structure of the integrated pile column is as follows: Figures 1 to 3 As shown, the first steel member 12 and the round steel 13 are both wrapped by the concrete of the precast concrete pile body 10 . A center hole 22 is provided in the middle of the precast concrete pile body 10 . The first steel member 12 and the round steel 13 are evenly arranged with the center hole 22 as the center.

[0071] The upper end plate 14 is connected to the upper end of the precast concrete pile body 10, and the lower end plate 15 is connected to the lower end of the precast concrete pile body 10. One end of the first steel member 12 is connected to the upper end plate 14, and the other end of the first steel member 12 passes through the lower end plate 15.

[0072] The connecting member 16 is arranged near the upper end of the precast concrete pile body 10 and near the lower end of the precast concrete pile body 10. One end of the connecting member 16 is connected to the first steel member 12, and the other end of the connecting member 16 extends out of the precast concrete pile body 10. The other end of the connecting member 16 is connected to the scissors column brace 19 and the auxiliary bracket 20.

[0073] The second steel member 17 is connected to the first steel member 12 extending out of the precast concrete pile body 10 to form a skeleton of the cast-in-place concrete foundation.

[0074] In a specific embodiment, the on-site construction method of the integrated pile column is as follows: the scissor column brace 19 connects the precast concrete pile bodies 10 in a group of integrated pile columns to maintain the distance accuracy and parallelism of the precast concrete pile bodies 10 in a group. The group of integrated pile columns is inserted into the corresponding on-site dug holes 18 and stands in the holes 18; refer to Figure 8 As shown, the integrated pile column and the hole 18 are arranged in a one-to-one correspondence. Then, the auxiliary bracket 20 is connected to the connector 16 on the precast concrete pile body 10, and the auxiliary bracket 20 is inserted into the ground, so that the auxiliary bracket 20 supports the group of precast concrete pile bodies 10 in the vertical dimension, so that the precast concrete pile body 10 maintains verticality with the ground. After the verticality of the precast concrete pile body 10 and the column spacing dimensional accuracy are controlled, the cast-in-place concrete 21 is injected into the hole 18, and after waiting for solidification or after the curing and curing are completed, the auxiliary bracket 20 is removed.

[0075] Since a part of the precast concrete pile body 10 is below the ground surface and is wrapped by cast-in-place concrete 21, and the first steel member 12 extending from the lower end of the precast concrete pile body 10 and the second steel member 17 fixed on the first steel member 12 form the skeleton of the cast-in-place concrete pile foundation, it is ensured that the lower part of the precast concrete pile body 10 is closely combined with the on-site excavation hole 18, thereby improving the reliability of the foundation; the upper part of the precast concrete pile body 10 directly extends out of the ground to form a column structure, which does not require the connection between the pile foundation and the column, thereby simplifying the structure. The precast concrete pile body 10 located above the ground is connected to other precast concrete pile bodies 10 in the same group through the connector 16 and the scissor column brace 19, thereby improving the ability of the integrated pile column to resist horizontal thrust.

[0076] In the embodiment of the present application, the number of a group of integrated piles is not specifically limited. Figure 8 and Fig. 9As shown, two adjacent integrated piles form a group, which are connected by a scissor column brace 19. For another example, three, four, etc. integrated piles form a group, which are arranged in a straight line. For another example, three, four, etc. integrated piles form a group, which are arranged in a triangle, circle, quadrilateral, etc.

[0077] Furthermore, part of the precast concrete pile body 10 and the steel structure body 11 are placed in the hole 18, and concrete 21 is poured in the hole 18, so that the part of the precast concrete pile body 10 and the steel structure body 11 are connected with the concrete 21 to form a micro bored pile. The micro bored pile is a bored pile with a smaller diameter. The diameter of the hole 18 is generally 10 cm to 30 cm, and the slenderness ratio is generally greater than 30. The pile body includes pressure-injected cement mortar or pebble concrete and a steel structure skeleton.

[0078] Furthermore, in order to improve the bonding force between the precast concrete pile body 10 and the cast-in-place concrete 21, the part of the precast concrete pile body 10 located underground is roughened. Roughening means treating the outer surface of the precast concrete pile body 10 buried underground into a rough surface to increase the friction between the precast concrete pile body 10 and the cast-in-place concrete 21, thereby improving the reliability of the precast concrete pile body 10 and the ground pile.

[0079] The integrated pile column of the embodiment of the present application has the advantages of simple structure and relatively low cost. The precast concrete pile body 10 is prefabricated, combined with the on-site cast-in-place micro-bored pile process, the precast concrete pile body 10 and the steel structure skeleton are inserted into the on-site excavation hole 18, and the concrete is poured on-site. The integrated pile column has fewer parts to be constructed on-site, and the on-site construction work is small, which can reduce the on-site construction period and construction costs, making the integrated pile column suitable for use in a variety of projects.

[0080] Optionally, the integrated piles of the embodiments of the present application can be applied to mountain photovoltaic systems as the basis of mountain photovoltaic systems. Among them, mountain photovoltaics refers to photovoltaic power generation systems built under mountain conditions. The integrated piles can meet the following characteristics of mountain photovoltaic system construction: In order to adapt to the geological conditions dominated by mountain gravel, micro-bored cast-in-place piles drilled on site are used as the foundation. In order to reduce the number of piles, the column spacing of the mountain photovoltaic system is increased in the length direction of the steel strand, and a scissor column brace 19 is set between a group of precast concrete pile bodies 10 of adjacent steel strands to improve the stability of the precast concrete pile body 10 and maintain the spacing.

[0081] The embodiment of the present invention also discloses a construction method of an integrated pile, which uses the integrated pile column in the above embodiment. In one embodiment, referring to Fig.10 As shown, the construction method comprises the following steps:

[0082] S01 , placing a portion of the precast concrete pile body 10 and the steel structure body 11 into the hole 18 .

[0083] In this step, the precast concrete pile body 10 and the steel structure body 11 are connected by the first steel member 12 , one end of the first steel member 12 is located in the precast concrete pile body 10 , and the other end of the first steel member 12 is located in the steel structure body 11 .

[0084] Hole 18 is a hole dug during on-site construction.

[0085] S02 , pouring concrete 21 into the hole 18 , so that part of the precast concrete pile body 10 and the steel structure body 11 are connected with the concrete 21 .

[0091] S12, connecting the second steel member 17 to the first steel member 12 to form a skeleton of the steel structure.

[0092] In this step, the first steel member 12 is part of the steel structure body 11. The skeleton of the steel structure can be used as the skeleton of the cast-in-place concrete 21.

[0093] It is understandable that the second steel member 17 and the first steel member 12 may be connected before being transported to the site, or may be connected on site, depending on the specific usage requirements.

[0094] S13 , placing a portion of the precast concrete pile body 10 and the steel structure body 11 into the hole 18 .

[0095] In this step, the hole 18 is a hole dug during on-site construction.

[0096] S14, installing the auxiliary support 20. The specific operation is to connect the precast concrete pile body 10 with one end of the auxiliary support 20, and insert the other end of the auxiliary support 20 into the ground.

[0097] In this step, the auxiliary support 20 is used to keep the precast concrete pile body 10 installed vertically, meeting the vertical installation requirements of the integrated pile column.

[0098] S15, pouring cast-in-place concrete into the on-site excavated hole 18.

[0099] In this step, the cast-in-place concrete needs to cover a portion of the precast concrete pile body 10 and the steel structure body 11 .

[0100] S16, carry out natural maintenance.

[0101] In this step, the natural curing cycle and curing method can be selected according to the use requirements, and the embodiments of the present application do not specifically limit this.

[0102] S17, after the cast-in-place concrete 21 reaches a specified strength, the auxiliary support 20 is removed. The construction is completed.
