[0052] A construction method of a steel pipe column pile combined support system specifically comprises the following steps:

[0053] S1. Foundation construction: sink the prefabricated PHC pile 1 into the ground as the foundation by hammering or static pressure, then pour the concrete base plate 2 on the ground, and embed a plurality of pre-embedded bolts 7 on the top;

[0054] S2, install the arc base 6: place the two arc bases 6 on the top of the concrete base plate 2, connect them with the prefabricated holes 13 through the embedded bolts 7 to ensure accurate installation, and use the elastic force mechanism of the protrusion 14 and the second spring 30 to fix the arc base 6 on the concrete base plate 2;

[0055] S3, column hoisting and positioning: hoist the prefabricated steel tube concrete column 4 and the positioning pile 8 from top to bottom into the concrete bottom plate 2, perform preliminary positioning through the positioning cavity 37, and use the No. 1 spring 25 and the contact plate 19 to position the column laterally to ensure its vertical state;

[0056] S4, column straightening: start the No. 1 push rod 17, clamp and straighten the column through the push plate 12 and the clamping plate to ensure the verticality of the column;

[0057] S5. Installation and adjustment of the support system: Install the support bottom plate 38 on the top of the concrete bottom plate 2, and adjust the height of the support top plate 41 through the outer sleeve 39 and the inner rod 40, adjust the inclination angle of the column by rotating the strip plate 44 and the U-shaped frame 43, and monitor the adjustment accuracy through the pointer 48 and the scale line 45;

[0058] S6, column fixing and completion: After the adjustment is completed, the prefabricated steel tube concrete column 4 is fixed on the supporting top plate 41 and the rotating strip plate 44. After the column is formed, the supporting system is retracted for subsequent reuse;

[0059] S7. Finishing and cleaning: After completing all installation work, clean up the construction site and check whether the connections between each component are firm to ensure construction quality.

[0060] When the steel pipe column pile combined support system is used, the prefabricated PHC pipe pile 1 is sunk into the ground by hammering or static pressure as the foundation of the building, and a concrete base plate 2 is poured on the ground. At this time, a plurality of embedded bolts 7 are embedded on the top of the concrete base plate 2, and two arc-shaped bases 6 are placed on the top of the concrete base plate 2. At this time, the prefabricated holes 13 and the embedded bolts 7 are butted to ensure the installation accuracy of the arc-shaped base 6;

[0061] At this time, the plurality of protrusions 14 first approach and squeeze the second spring 30 and then enter the interior of the insertion hole 9, and then the elastic force of the second spring 30 drives the two vertical plates 29 away, and the vertical plates 29 drive the protrusions 14 to enter the interior of the limiting cavity 10, and the two arc-shaped bases 6 are fixed to ensure the stability of the arc-shaped base 6. At this time, the positioning piles 8 and the prefabricated steel tube concrete column 4 can be hoisted from top to bottom;

[0062] At this time, after the prefabricated steel tube concrete column 4 and the positioning pile 8 enter the interior of the concrete bottom plate 2, they are initially positioned through the positioning cavity 37. At this time, the contact plate 19 moves laterally under the elastic force of the No. 1 spring 25, and the positioning rod 26 moves out from the interior of the positioning groove 27. At this time, multiple contact plates 19 will position the prefabricated steel tube concrete column 4 from the side to ensure that the prefabricated steel tube concrete column 4 is in a vertical state;

[0063] At this time, the No. 1 push rod 17 can be started, the piston rod of the No. 1 push rod 17 is retracted, the piston rod of the No. 1 push rod 17 drives the push plate 12 to be retracted, the push plate 12 drives the first round rod 16 to move laterally, the first round rod 16 drives the lower clamping plate 15 to move laterally, the lower clamping plate 15 clamps the prefabricated steel tube concrete column 4, at this time it can help the prefabricated steel tube concrete column 4 to perform the straightening process, at the same time the lower clamping plate 15 drives the upper clamping plate 11 to move laterally through the support rod 5, the upper clamping plate 11 helps clamp the upper half of the prefabricated steel tube concrete column 4;

[0064] When the straightening is completed and the equipment needs to be retracted, the piston rod of the No. 1 push rod 17 can be extended, and then the lower clamping plate 15 can no longer resist the sliding block 18. At this time, one end of the sliding block 18 moves out from the gap between the arc plate 22 and the arc base 6, and the second round rod 21 is quickly retracted under the tension of the No. 3 spring 34. The second round rod 21 drives the arc plate 22 to retract. At this time, the contact plate 19 and the lower clamping plate 15 no longer clamp the prefabricated steel tube concrete column 4, which can facilitate the removal of the arc base 6;

[0065] like Fig.12 As shown, the arc plate 22 drives the convex plate 20 to move horizontally, and the convex plate 20 enters the interior of the second rectangular hole 36 and uses the inclined surface to conflict with the connecting plate 28. At this time, the convex plate 20 can push the connecting plate 28 to move horizontally, and the connecting plate 28 moves toward the direction of the vertical plate 29. Since the connecting plate 28 and the clearance groove 31 are located on the same horizontal plane, the connecting plate 28 drives the two arc blocks 24 to move horizontally. The arc blocks 24 enter the interior of the clearance groove 31 and drive the two vertical plates 29 to approach each other. At this time, the vertical plate 29 drives the two protrusions 14 to approach each other, and the protrusions 14 can be moved out of the interior of the limiting cavity 10. At this time, the two arc bases 6 can be moved vertically upward and taken out separately from both sides of the prefabricated steel tube concrete column 4, which reduces the difficulty of operation and is convenient for reuse;

[0066] A support bottom plate 38 is installed on both sides of the top of the concrete bottom plate 2, and the support top plate 41 is supported by the outer sleeve 39 and the inner rod 40. By starting the No. 2 push rod 42, the piston rod of the No. 2 push rod 42 is extended, and the height of the support top plate 41 can be adjusted. The same rotating strip plate 44 is rotatably connected between the two support top plates 41. At this time, the angle of the rotating strip plate 44 can drive the U-shaped frame 43 to be adjusted. Since the arc sleeve 46 is rotatably connected to the fixed rod 47, the current inclination degree of the rotating strip plate 44 can be understood through the pointer 48 and the scale line 45. After the adjustment is completed, the same prefabricated steel tube concrete column 4 is set on the top of the rotating strip plate 44 and the support top plate 41. After the prefabricated steel tube concrete column 4 is formed, the piston rod of the No. 2 push rod 42 is retracted. At this time, the shelf can be retracted from one side for easy reuse.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
