[0068] like Figures 1 to 5As shown, according to an embodiment of the present invention, a steel pipe column installation machine 100 is proposed for the construction of ground pile columns. The steel pipe column installation machine 100 includes a base 20, a vertical adjustment component 30, a horizontal adjustment component 40, a movable seat 60 and a clamping component 50. The base 20 is provided with a first through hole 21 for the steel pipe column to pass through. The vertical adjustment component 30 is arranged on the base 20, and the base 20 contacts the working surface through the vertical adjustment component 30. The movable seat 60 is arranged on the base 20. The movable seat 60 is provided with a second through hole 61 for the steel pipe column to pass through. At least part of the second through hole 61 is connected to the first through hole 21. The clamping component 50 is arranged on the movable seat 60. The clamping component 50 is used to hold the steel pipe column. The horizontal adjustment component 40 cooperates with the movable seat 60 and is used to drive the movable seat 60 to move relative to the base 20. The horizontal adjustment component 40 cooperates with the clamping component 50 and is used to drive the clamping component 50 to move relative to the movable seat 60. The moving directions of the movable seat 60 and the clamping component 50 are perpendicular.

[0069] Specifically, when constructing ground piles, the steel pipe column installation machine 100 is set at the working surface to be constructed (a pile hole is previously opened at the location to be constructed, and a steel cage is set in the pile hole), the clamping assembly 50 is in an open state, and the insertion end of the steel pipe column with an open structure is inserted into the pile hole through the clamping assembly 50, the second through hole 61 and the first through hole 21 in sequence. When the insertion end of the steel pipe column reaches the preset position, the clamping assembly 50 is held on the outside of the steel pipe column so that the steel pipe column is maintained at the current position, and the vertical adjustment assembly 30 is started, thereby adjusting the vertical direction of the steel pipe column to avoid the steel pipe column from tilting, so that the verticality of the steel pipe column is guaranteed. The horizontal adjustment component 40 is started, thereby adjusting the horizontal direction of the steel pipe column to avoid the horizontal displacement of the steel pipe column, so that the horizontal position of the steel pipe column is guaranteed. When the vertical and horizontal directions of the steel pipe column meet the design requirements, concrete is poured. After the concrete is solidified, the clamping component 50 is released from the steel pipe column and the steel pipe column installation machine 100 is removed.

[0070] By means of the steel pipe column installation machine 100 , the installation accuracy of the steel pipe column is ensured, thereby ensuring the quality of the ground pile column construction.

[0071] It should be understood that all components of the steel pipe column installation machine 100 are arranged on the base 20, and the vertical adjustment assembly 30 is arranged on the end face of the base 20 facing the working surface and in contact with the working surface, that is, the base 20 is in contact with the working surface through the vertical adjustment assembly 30. When the clamping assembly 50 holds the steel pipe column, the base 20 moves in a direction closer to or away from the working surface (including the linear movement of the base 20 and the inclination of the base 20) by adjusting the vertical adjustment assembly 30, so that the verticality of the steel pipe column meets the design requirements, thereby ensuring the construction quality of the ground pile column.

[0072] In addition, the first through hole 21 is arranged on the base 20, and the second through hole 61 is arranged on the movable seat 60. The movable seat 60 can move relative to the base 20 through the horizontal adjustment component 40. The second through hole 61 and the first through hole 21 can be in a coaxial state (the second through hole 61 is completely connected with the first through hole 21), and can also be in a non-coaxial state (at least the second through hole 61 is completely connected with the first through hole 21). When the clamping component 50 clamps the steel pipe column, the horizontal adjustment component 40 drives the movable seat 60 to move relative to the base 20. The movement of the movable seat 60 drives the clamping component 50 and the steel pipe column to move horizontally, thereby realizing the horizontal adjustment of the steel pipe column, thereby ensuring the horizontal position of the steel pipe column, and thereby ensuring the construction quality of the ground pile.

[0073] It should be pointed out that the horizontal adjustment assembly 40, the movable seat 60 and the clamping assembly 50 are located on one side of the base 20, and the vertical adjustment assembly 30 is located on the other side of the base 20. The steel pipe column installation machine 100 also includes a covering assembly 10. The horizontal adjustment assembly 40, the movable seat 60 and the clamping assembly 50 are all wrapped by the covering assembly 10. By providing the covering assembly 10, the horizontal adjustment assembly 40, the movable seat 60 and the clamping assembly 50 can be prevented from being affected by the external environment, thereby reducing the failure rate of the steel pipe column installation machine 100 and ensuring the construction efficiency.

[0074] Specifically, the covering assembly 10 includes a top plate 11, a side panel 12, a handrail 13 and an escalator 14, wherein the side panel 12, the top plate 11 and the base 20 are combined to form a box-type structure, the horizontal adjustment assembly 40, the movable seat 60 and the clamping assembly 50 are all encapsulated in the box-type structure, and an inspection door is provided on the side panel 12, through which maintenance personnel can repair the horizontal adjustment assembly 40, the movable seat 60, the clamping assembly 50 and other components, the handrail 13 is arranged on the outer side of the top plate 11 and forms a circumferential protection for the top plate 11, and a working space is formed between the handrail 13 and the top plate 11, and construction personnel can enter the working space to check or operate the steel pipe column installation machine 100 during the operation process, etc., thereby improving the convenience of construction personnel in construction, and the handrail 14 cooperates with the handrail 13 and extends from the working surface to the outer side of the top plate 11, and the handrail 14 is provided to facilitate construction personnel to enter or leave the working space, further improving the convenience of users.

[0075] It is further understood that if Figures 1 to 3As shown, the clamping assembly 50 includes a base frame 51, a first driving member 53 and a movable frame 52. The base frame 51 is movably arranged on the movable seat 60 and cooperates with the horizontal adjustment assembly 40. One end of the first driving member 53 is connected to the base frame 51, and the other end of the first driving member 53 is connected to the movable frame 52. A clamping space 54 for the steel pipe column to pass through is formed between the movable frame 52 and the base frame 51. The first driving member 53 can drive the movable frame 52 to move relative to the base frame 51 to adjust the size of the clamping space 54. Specifically, the clamping space 54 is arranged corresponding to the second through hole 61 and the first through hole 21. When installing the steel pipe column, the first driving member 53 drives the movable frame 52 to move away from the base frame 51. At this time, the clamping space 54 increases (the clamping assembly 50 is in an open state), and the insertion end of the steel pipe column with an open structure is inserted into the pile hole through the clamping space 54, the second through hole 61 and the first through hole 21 in sequence. When the steel pipe column is inserted into the preset position, the first driving member 53 drives the movable frame 52 to move toward the base frame 51. At this time, the holding space becomes smaller. Under the action of the first driving member 53, the movable frame 52 and the fixing member are respectively tightly pressed against the outer surface of the steel pipe column, thereby realizing the holding of the steel pipe column and effectively ensuring the installation position of the steel pipe column. In addition, when the movable frame 52 moves relative to the base frame 51 under the action of the first driving member 53 to hold the steel pipe column, the initial positioning of the steel pipe column is achieved, thereby ensuring the installation accuracy of the steel pipe column and the construction quality of the ground pile column.

[0076] It should be pointed out that the axis of the clamping space 54 coincides with the axis of the second through hole 61. When the movable frame 52 and the base frame 51 clamp the steel pipe column, the axis of the steel pipe column coincides with the axis of the clamping space, that is, the steel pipe column and the second through hole 61 are coaxially arranged. When the movable seat 60 moves for horizontal adjustment, interference factors affecting the installation accuracy are reduced, thereby further improving the installation accuracy of the steel pipe column.

[0077] Furthermore, if Figures 1 to 3As shown, the base frame 51 includes a support portion 512 and a clamping portion 511, the support portion 512 is arranged on the movable seat 60, the support portion 512 is provided with a third through hole 5121 for connecting the steel pipe column, the third through hole 5121 is connected with the second through hole 61, the movable frame 52 is movably arranged on the support portion 512, the clamping portion 511 is arranged at one end of the support portion 512, the end surface of the clamping portion 511 facing the movable frame 52 is provided with a first groove 5111, the end surface of the movable frame 52 facing the clamping portion 511 is provided with a second groove 521, the first groove 5111 and the second groove 521 are surrounded to form a clamping space 54, specifically, the clamping portion 511 is located at the support portion 512 At one end, the clamping part 511 and the supporting part 512 form an L-shaped structure, the first groove 5111 is connected to the third through hole 5121 and the contact position of the two is flush, the movable frame 52 is slidably arranged on the supporting part 512, the first groove 5111 and the second groove 521 are arranged opposite to each other, one end of the first driving member 53 is connected to the bottom frame 51, and the other end of the first driving member 53 is connected to the movable frame 52, and the first driving member 53 can only drive the movable frame 52 to move in the direction of approaching or moving away from the clamping part 511. Under the action of the first driving member 53, the first groove 5111 and the second groove 521 respectively abut against the outer surface of the steel pipe column, thereby achieving the holding of the steel pipe column. The overall structure of the holding assembly is simple, and the installation position of the steel pipe column can be effectively maintained, thereby improving the installation accuracy of the steel pipe column, so that the construction quality of the ground pile column is guaranteed.

[0078] It should be understood that the shapes of the first groove 5111 and the second groove 521 are adapted to the shape of the outer surface of the steel pipe column. When the movable frame 52 and the base frame 51 are respectively used to hold the steel pipe column, the contact area between the two and the steel pipe column can be increased, thereby improving the strength and stability of the holding of the steel pipe column, further ensuring the installation position of the steel pipe column, and further improving the construction quality of the ground piles.

[0079] Specifically, if Figures 1 to 3 As shown, there are two first driving members 53, and the two first driving members 53 are located on opposite sides of the movable frame 52. The two first driving members 53 are arranged in parallel and spaced apart. When the steel pipe column is held, the two first driving members 53 are started synchronously, so that the two sides of the movable frame 52 are evenly stressed, avoiding damage to the movable frame 52 due to stress concentration. In addition, the two first driving members 53 can increase the driving force on the movable frame 52, thereby improving the holding strength of the holding assembly on the steel pipe column, avoiding the displacement of the steel pipe column and affecting the installation accuracy.

[0080] Specifically, if Figures 1 to 3As shown, the first driving member 53 is a first oil cylinder. The first oil cylinder seat of the first oil cylinder cooperates with the base frame 51, the first cylinder rod of the first oil cylinder cooperates with the movable frame 52, the telescopic direction of the first cylinder rod is consistent with the moving direction of the movable frame 52, the linear driving ability of the first oil cylinder is good, and the moving direction of the movable frame 52 can be effectively guaranteed, thereby improving the clamping accuracy of the steel pipe column. In addition, the first oil cylinder has high strength, which can provide a stable driving force for the base frame 51 and the movable frame 52 to clamp the steel pipe column, further improving the installation accuracy of the steel pipe column.

[0081] In other embodiments, the first driving member 53 is a first cylinder, thereby effectively reducing the manufacturing cost of the steel pipe column installation machine 100 .

[0082] Furthermore, if Figures 1 to 3 As shown, the horizontal adjustment assembly 40 includes a second driving member 41 and a third driving member 42. The second driving member 41 cooperates with the movable seat 60 and the clamping assembly 50 respectively and is used to drive the clamping assembly 50 to move. The third driving member 42 cooperates with the movable seat 60 and the base 20 respectively and is used to drive the movable seat 60 to move. The driving direction of the third driving member 42 is perpendicular to the driving direction of the second driving member 41 and both are located in the horizontal plane. Specifically, the horizontal plane formed by the horizontal direction includes the horizontal direction and the longitudinal direction. The second driving member 41 drives the clamping assembly 50 to move horizontally, and the third driving member 42 drives the movable seat 60 to move longitudinally. Through the cooperation of the second driving member 41 and the third driving member 42, the clamping assembly 50 moves relative to the movable seat 60, and the movable seat 60 moves relative to the base 20, thereby driving the steel pipe column to the preset position, avoiding the situation where the installation accuracy of the steel pipe column is reduced due to horizontal displacement, and effectively improving the construction quality of the ground pile column.

[0083] It should be pointed out that when the steel pipe column is installed, the first through hole 21 on the base 20 is coaxially arranged with the pile hole, thereby reducing the adjustment stroke of the horizontal adjustment assembly 40 on the steel pipe column, thereby improving the construction efficiency.

[0084] Furthermore, if Figures 1 to 3 As shown, there are two second driving members 41, and the two second driving members 41 are located on opposite sides of the clamping assembly 50. Specifically, the two second driving members 41 are arranged in parallel and spaced apart. When the horizontal position of the steel pipe column is adjusted, the two second driving members 41 are started synchronously, so that the two sides of the clamping assembly 50 are evenly stressed, avoiding the situation where the clamping assembly 50 is damaged due to stress concentration. In addition, the two second driving members 41 can increase the driving force of the clamping assembly 50, thereby improving the adjustment rate and further improving the construction efficiency.

[0085] Specifically, if Figures 1 to 3As shown, the second driving member 41 is a second oil cylinder. The second oil cylinder seat of the second oil cylinder cooperates with the base 20, the second cylinder rod of the second oil cylinder cooperates with the movable seat 60, the telescopic direction of the second cylinder rod is consistent with the moving direction of the clamping assembly 50, the second oil cylinder has good linear driving ability, can effectively ensure the moving direction of the clamping assembly 50, thereby improving the installation accuracy of the steel pipe column, in addition, the second oil cylinder has high strength, can provide a stable driving force for the clamping assembly 50, and further improves the installation efficiency of the steel pipe column.

[0086] In other embodiments, the second driving member 41 is a second cylinder, thereby effectively reducing the manufacturing cost of the steel pipe column installation machine 100 .

[0087] Specifically, if Figures 1 to 3 As shown, there are two third driving members 42, and the two third driving members 42 are located on opposite sides of the movable seat 60. The two third driving members 42 are arranged in parallel and spaced apart. When the horizontal position of the steel pipe column is adjusted, the two third driving members 42 are started synchronously, so that the two sides of the movable seat 60 are evenly stressed, avoiding the damage of the movable seat 60 due to stress concentration. In addition, the two third driving members 42 can increase the driving force on the movable seat 60, thereby improving the adjustment rate and further improving the construction efficiency.

[0088] Specifically, the third driving member 42 is a third oil cylinder. The third oil cylinder seat of the third oil cylinder cooperates with the base 20, the third cylinder rod of the third oil cylinder cooperates with the movable seat 60, the extension direction of the third cylinder rod is consistent with the moving direction of the movable seat 60, the third oil cylinder has good linear driving ability, and can effectively ensure the moving direction of the movable seat 60, thereby improving the installation accuracy of the steel pipe column, and in addition, the third oil cylinder has high strength, which can provide a stable driving force for the movable seat 60, further improving the installation efficiency of the steel pipe column.

[0089] In other embodiments, the third driving member 42 is a third cylinder, thereby effectively reducing the manufacturing cost of the steel pipe column installation machine 100 .

[0090] Furthermore, if Figures 1 to 3 As shown, the vertical adjustment assembly 30 includes a first anchor 31 and a fourth drive member 32. The first anchor 31 is used to abut against the working surface. The first anchor 31 is connected to the base 20 through the fourth drive member 32. The fourth drive member 32 drives the base 20 to move in a direction close to or away from the working surface. Specifically, the first anchor 31 abuts against the working surface. The first anchor 31 is connected to the base 20 through the fourth drive member 32. When the vertical direction of the steel pipe column needs to be adjusted, the fourth drive member 32 is started, so that the base 20 moves in a direction close to or away from the working surface, thereby realizing the adjustment of the steel pipe column in its vertical upward direction, further improving the installation accuracy of the steel pipe column, and ensuring the construction quality of the ground pile column.

[0091] Furthermore, if Figures 1 to 3 As shown, the vertical adjustment assembly 30 also includes a second foot 33 and a screw 34. The second foot 33 is spaced apart from the first foot 31 and is used to abut against the working surface. The second foot 33 is fixed to one end of the screw 34. The screw 34 is threadedly matched with the base 20. The screw 34 can rotate relative to the base 20 to make the base 20 move toward or away from the second foot 33. Specifically, after the fourth driving base 20 moves relative to the first foot 31 to adjust the steel pipe column in its vertical direction, the second foot 33 drives the screw 34 to rotate relative to the base 20, and the second foot 33 abuts against the working surface. By setting the second foot 33 and the screw 34, the steel pipe column can be finely adjusted in its vertical direction. In addition, the second foot 33 and the screw 34 can be provided to provide auxiliary support for the base 20, thereby ensuring the stability of the base 20 and further improving the installation accuracy of the steel pipe column.

[0092] Furthermore, if Figure 2 As shown, the number of the first anchors 31 is three, the number of the fourth driving members 32 is the same as the number of the first anchors 31, and each first anchor 31 is arranged in a triangle. Specifically, the three fourth driving members 32 are arranged in a triangle on the end surface of the base 20 facing the working surface, so that the three first anchors 31 are arranged in a triangle, and each fourth driving member 32 is driven separately, and the base 20 is leveled by using the triangle principle, and then the steel pipe column is leveled, so that the verticality of the steel pipe column is guaranteed. In addition, the three first anchors 31 are arranged in a triangle, thereby improving the stability of the steel pipe column installation machine 100 and further ensuring the installation accuracy of the steel pipe column.

[0093] Specifically, the fourth driving member 32 is a fourth oil cylinder. The fourth oil cylinder seat of the fourth oil cylinder cooperates with the base 20, the fourth cylinder rod of the fourth oil cylinder cooperates with the first foot 31, the extension direction of the fourth cylinder rod is consistent with the moving direction of the first foot 31, the fourth oil cylinder has good linear driving ability, can effectively ensure the moving direction of the base 20, thereby improving the installation accuracy of the steel pipe column, in addition, the fourth oil cylinder has high strength, can provide a stable driving force for the base 20, and further improves the installation accuracy of the steel pipe column.

[0094] In other embodiments, the fourth driving member 32 is a fourth cylinder, thereby effectively reducing the manufacturing cost of the steel pipe column installation machine 100 .

[0095] Specifically, if Figure 2As shown, the number of the second anchors 33 is three, the number of the screw rods 34 is the same as the number of the second anchors 33, and the second anchors 33 are arranged alternately with the first anchors 31. By arranging a plurality of second anchors 33 and screw rods 34, the support strength of the base 20 can be further improved, so that the stability of the steel pipe column is further guaranteed, thereby improving the installation accuracy of the steel pipe column.

[0096] In addition, if Figure 4 As shown, in the present application, the steel pipe column installation machine 100 also includes a controller, and a hydraulic station, a display screen, a first sensor, a second sensor, a human-computer interaction module and a wireless communication module electrically connected to the controller respectively, wherein the hydraulic station is connected to the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder and the fourth hydraulic cylinder respectively, and the controller controls the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder and the fourth hydraulic cylinder by controlling the hydraulic station, thereby improving the convenience of control; the display screen is used to display the working status information of the steel pipe column installation machine 100, so that construction personnel can timely and effectively grasp the current status of the steel pipe column installation machine 100; the first sensor, the first sensor is an inclination sensor and is arranged on the top of the steel pipe column. The current status of the steel pipe column is detected in real time by the first sensor, and the controller detects the current status of the steel pipe column according to the first sensor. The data detected by one sensor drives the horizontal adjustment component 40 and the vertical adjustment component 30, so that the installation position of the steel pipe column meets the design requirements, thereby ensuring the construction quality of the ground pile column; the second sensor is a position sensor, and the second sensor is arranged on the steel pipe column. By setting the second sensor, the steel pipe column can be positioned, and the controller adjusts the horizontal position of the steel pipe column according to the position of the second sensor, further ensuring the installation accuracy of the steel pipe column; the human-computer interaction module is used for the input of control instructions by construction personnel, further improving the convenience of construction personnel's operation; the controller communicates with the mobile terminal (smartphone, IPD or laptop computer, etc.) through the wireless communication module, and the construction personnel can control the steel pipe column installation machine 100 by operating the mobile terminal, further improving the convenience of construction personnel during construction.

[0097] like Figures 1 to 5 As shown, the present invention also proposes a ground pile construction method, which is implemented according to the above steel pipe column installation machine 100, and the ground pile construction method includes the following steps:

[0098] Open the pile hole. Specifically, on the basis of the three connections and one leveling of the working surface, according to the data of the building measurement control network and the foundation plan, the pile axis grid control network and the elevation reference point are determined, the pile center is determined, and the midpoint is used as the circle point, and the radius of the pile body plus the thickness of the retaining wall is used as the radius to draw the circumference of the upper part (i.e. the first section), and the lime line is used as the pile hole excavation dimension line, and four pile center axis control points are drawn out of the pile hole along the center position of the pile, and marked with solid wooden stakes. After the pile position line is determined, excavation will be carried out after the re-inspection and acceptance.

[0099] The steel cage is arranged in the pile hole. Specifically, the steel cage is placed in the pile hole by a hoisting device, and the steel cage and the pile hole are arranged concentrically, thereby ensuring uniform strength of the ground pile column.

[0100] In addition, after the steel cage is placed, the steel pipe column installation machine 100 is set at the pile hole so that the first through hole 21 is arranged in line with the pile hole.

[0101] The steel pipe column with an open insertion end is inserted into the pile hole. Specifically, the steel pipe column has an open structure at both ends, and the insertion end is inserted into the pile hole through the holding space of the steel pipe column installation machine 100, the second through hole 61 and the first through hole 21 by using a lifting device.

[0102] After the steel pipe column reaches the preset position, the steel pipe column outside the pile hole is clamped. Specifically, the lifting equipment is lowered so that the steel pipe column is continuously inserted into the pile hole. When the steel pipe column reaches the preset position, the lifting equipment stops, the steel pipe column installation machine 100 starts, the clamping assembly 50 holds the steel pipe column, and the lifting equipment is separated from the steel pipe column.

[0103] Adjust the horizontal position and verticality of the steel pipe column. Specifically, the steel pipe column adjusts the verticality and horizontal position of the steel pipe column according to the information detected by the first sensor and the second sensor, so that the position of the steel pipe column meets the design requirements, thereby ensuring the construction quality of the ground pile column.

[0104] In addition, after the adjustment of the steel pipe column is completed, the guide pipe is lowered and the hole is cleaned for the second time to further ensure the construction quality of the ground pile column.

[0105] Pour concrete. Specifically, first pour the pile foundation concrete to the designed elevation, then pour C60 concrete, then fill the outside of the column with gravel, and finally pour the steel pipe column C60 concrete to the column top elevation (backfill gravel between the steel pipe column and the hole wall).

[0106] After a preset time, the steel pipe column is released. Specifically, the preset time is 30 hours, so as to ensure that the concrete can solidify effectively, thereby ensuring the construction quality of the ground pile column.

[0107] In the existing HPE method, when the steel pipe column is inserted into the poured concrete, the insertion end of the steel pipe column is a closed structure, and the buoyancy makes it difficult to insert the steel pipe column, which affects the installation accuracy of the steel pipe column. Compared with the prior art, in the construction method of the ground pile column of the present invention, the insertion end of the steel pipe column is an open structure and is inserted into the pile hole before the concrete is poured, and the installation accuracy of the steel pipe column is guaranteed by using a steel pipe column installation machine, thereby ensuring the quality of the ground pile column construction.

[0108] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
