[0008] Preferably, the cross section of the limiting column is set to be square.

[0009] Beneficial effects:

[0010] 1. The pile foundation structure of the house construction uses a support seat and a support rod to enable the hydraulic cylinder to support the load-bearing column. At the same time, the cylinder body, sealing cover, internal threaded sleeve, limit column, pressure rod and limit boss are used together, so that when the piston rod inside the hydraulic cylinder moves, the hydraulic oil pressure piston can compress the spring, thereby enabling the hydraulic cylinder to buffer and reduce vibration of the load-bearing column. Compared with using springs alone to support the load-bearing column, this structure can effectively support the load-bearing column through the added hydraulic cylinder and spring.

[0011] 2. The pile foundation structure of the house construction can drive the pressure rod to move downward along its own axial direction by rotating the internal threaded sleeve while compressing the spring, thereby adjusting the elastic force of the spring acting on the piston, so that the force of the hydraulic oil acting on the piston rod inside the hydraulic cylinder can be adjusted. Even if the elastic performance of the spring inside the load-bearing sleeve decreases after long-term use, this structure can effectively buffer and reduce vibration of the load-bearing column through the hydraulic cylinder.

The support seat 5 is internally movably sleeved with a support rod 6 fixedly sleeved inside the load-bearing column 2. The support seat 5 can be used to limit the support rod 6 to prevent the support rod 6 from bending and deforming during the process of the hydraulic cylinder 7 supporting the load-bearing column 2 through the support rod 6, so as to ensure that the hydraulic cylinder 7 can have The load-bearing column 2 is effectively supported by the support rod 6. The outer sides of both ends of the support rod 6 are movably sleeved with a hydraulic cylinder 7 whose bottom is fixedly installed on the load-bearing platform, and the outer sides of both ends of the support rod 6 extending out of the hydraulic cylinder 7 are clamped with a first clamping ring 8. The first clamping ring 8 can be used to limit the hydraulic cylinder 7 and facilitate the disassembly and assembly of the hydraulic cylinder 7. The outer side of the hydraulic cylinder 7 is fixedly sleeved with a cylinder body 9, and the outer side of the top of the cylinder body 9 is threadedly sleeved with a sealing cover 10. The outer side of the bottom end of the hydraulic cylinder 7 is connected to the bottom of the cylinder body 9 through a flow regulating mechanism 11, and the inner side of the sealing cover 10 is movably sleeved with an adjusting mechanism 12 located inside the cylinder body 9.

[0021] Among them, the flow regulating mechanism 11 includes a first hydraulic pipe 111 connected to the bottom end of the hydraulic cylinder 7 and a second hydraulic pipe 112 connected to the bottom end of the cylinder body 9. A throttle valve 113 is connected between the first hydraulic pipe 111 and the second hydraulic pipe 112. The throttle valve 113 can be used to adjust the flow rate of the hydraulic oil between the first hydraulic pipe 111 and the second hydraulic pipe 112, and then by changing the flow rate of the hydraulic oil between the hydraulic cylinder 7 and the cylinder body 9, the piston rod inside the hydraulic cylinder 7 can move slowly, so that the hydraulic cylinder 7 can buffer the load-bearing column 2.

[0022] Among them, the adjusting mechanism 12 includes a piston 121 movably mounted inside the cylinder body 9 and an internal threaded sleeve 122 movably mounted inside the sealing cover 10, a limiting column 123 is arranged on the top of the piston 121, the internal thread of the internal threaded sleeve 122 is connected with a pressure rod 124 which is mounted on the outside of the limiting column 123 and mounted inside the top end of the cylinder body 9, a second clamping ring 125 is clamped on the outside of the top end of the internal threaded sleeve 122 extending out of the sealing cover 10, a spring 126 which is mounted inside the cylinder body 9 and located on the outside of the limiting column 123 is placed between the piston 121 and the pressure rod 124, a limiting boss 127 adapted to the cylinder body 9 is arranged on the outside of the pressure rod 124, and the pressure rod 124 can be limited by the limiting boss 127, so that when the internal threaded sleeve 122 rotates, the pressure rod 124 can move along its own axial direction and compress the spring 126 at the same time.

[0024] The cross section of the limiting column 123 is set to be a square. By setting the limiting column 123 to a square structure, the pressure rod 124 can limit the piston 121 while preventing the piston 121 from rotating, thereby reducing the wear of the piston 121.

[0025] When adjusting the supporting force of the hydraulic cylinder 7, the limit on the bolt 14 can be released by loosening the bolt 14, and the pressure rod 124 can be driven to move along its own axial direction by rotating the internal threaded sleeve 122 while compressing the spring 126. The supporting force of the hydraulic cylinder 7 on the load-bearing column 2 is adjusted by changing the elastic force of the spring 126 acting on the piston 121. After the supporting force is adjusted, the bolt 14 is tightened and the internal threaded sleeve 122 is limited and fixed by the bolt 14.
