Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a leveling device and method for a composite foundation of long and short piles. Background Technology

[0002] In civil engineering construction, pile foundations are undoubtedly the preferred foundation type for large building structures in terms of settlement and bearing capacity control. However, the cost of pile foundations is relatively high in multi-story and mid-rise buildings. In order to meet the engineering needs while reducing the cost of foundation treatment, composite foundations have emerged, among which the composite foundation of long and short piles is the most prominent. It fully utilizes the bearing capacity of the natural soil and reduces settlement. It meets the structural requirements of the superstructure, reduces the impact of pile driving on the surrounding environment, and greatly reduces the cost of foundations. It is a foundation type that has been widely adopted in multi-story and mid-rise projects in recent years.

[0003] Composite foundations with long and short piles utilize a design that combines long and short piles. A higher density of piles is placed in the upper soil layer where additional stress is high, while the pile density is reduced in the lower soil layer. By adjusting the pile length, the bearing capacity of the composite foundation is ensured while the settlement of the underlying layer is reduced due to the longer piles, thus controlling the total settlement of the composite foundation to meet design requirements. To ensure that the settlement meets design requirements, leveling devices are typically used to monitor and measure the piles in the upper soil layer, ensuring that the pile settlement meets the target requirements within a specified time. Any abnormal pile settlement is addressed promptly. However, current leveling devices for composite foundations with long and short piles still have the following shortcomings:

[0004] The existing leveling devices are not easy to disassemble and assemble quickly, and the process is relatively cumbersome, resulting in low leveling and testing efficiency for composite foundations of long and short piles, and poor applicability. They are not easy to match with piles of various sizes, nor are they easy to adapt to various pile embedment depths, thus they cannot be better suited for leveling operations of composite foundations of long and short piles.

[0005] Therefore, there is an urgent need to improve this shortcoming. The present invention studies and improves the existing structure and its deficiencies, and provides a leveling device and leveling method for composite foundations of long and short piles. Summary of the Invention

[0006] The purpose of this invention is to provide a leveling device and a leveling method for composite foundations with long and short piles, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a leveling device for a composite foundation of long and short piles, comprising a fixing frame and a control box. A threaded sleeve is fixedly connected to the bottom of the fixing frame, and a support component is threadedly connected to the inner side of the threaded sleeve. A connector is fixedly connected to one side of the fixing frame, and an adjustment component is fixedly connected to the inner surface of the connector. A mounting frame is connected to the bottom of the adjustment component, and an identification device is fixedly installed on the inner side of the mounting frame. A measuring tape is fixedly installed on the inner side of the mounting frame, and a connecting hook is fixedly connected to the end of the measuring tape. The control box is located directly below the mounting frame, and a metal ring is welded to the top of the control box. A locking component is fixedly installed at the bottom of the control box, and a pile body is connected to the inner side of the locking component. A slot is formed on the surface of the pile body.

[0008] Furthermore, the support assembly includes a support column, a chassis, and a support rod. The top end of the support column is threaded and engages with the inner wall of a threaded sleeve via the thread. The bottom end of the support column is fixedly connected to the chassis. The outer wall of the support column is welded with a support rod, and the bottom end of the support rod is welded to the top of the chassis. The support column, chassis, and support rod form an integrated structure.

[0009] Furthermore, the adjustment assembly includes a housing, a limiting slide rail, a first bearing, a metal screw, and a first handle. The limiting slide rail is fixedly connected to the inner side wall of the housing, and the first bearing is fixedly connected to the inner bottom wall of the housing. The metal screw is fixedly connected to the inner wall of the first bearing, and the first handle is fixedly connected to the top end of the metal screw.

[0010] Furthermore, the adjustment assembly also includes a threaded tube and a lifting frame, with the threaded tube sleeved on the outside of the metal lead screw, and the inner wall of the threaded tube threadedly connected to the inner wall of the metal lead screw. The outer wall of the threaded tube is fixedly connected to the lifting frame, and the threaded tube and the lifting frame are embedded in each other.

[0011] Furthermore, the adjustment assembly also includes a limiting slider and a connecting rod. The limiting slider is fixedly installed on the left and right sides of the lifting frame, and the lifting frame forms a sliding structure with the limiting slide rail through the limiting slider. The bottom of the lifting frame is fixedly connected to the connecting rod, and the bottom end of the connecting rod is welded to the top of the mounting frame.

[0012] Furthermore, the control box includes a housing, a limiting groove, a second bearing, a double-acting screw, and a second handle. The top of the housing has a limiting groove, and the inner wall of the housing is fixedly installed with the second bearing. The inner wall of the second bearing is fixedly connected with the double-acting screw, and the end of the double-acting screw is fixedly connected with the second handle.

[0013] Furthermore, the control box also includes a limit plate, a movable block, a slide button, and a connecting seat. The limit plate is sleeved on the outer wall of the bidirectional lead screw, and the movable block is threadedly connected to the outer wall of the bidirectional lead screw. The top of the movable block is fixedly connected to the slide button, and the bottom of the movable block is fixedly connected to the connecting seat. The bottom of the connecting seat is fixedly connected to the top of the locking assembly.

[0014] Furthermore, the locking assembly includes a fixed seat, a wrench, a crossbeam frame, and a side sliding groove. The wrench is connected to the inner side of the fixed seat via a pivot, and the crossbeam frame is fixedly connected to the inner side wall of the fixed seat. The outer wall of the crossbeam frame is provided with a side sliding groove.

[0015] Furthermore, the locking assembly also includes a sliding frame, a sliding bolt, a buffer spring, an arc-shaped plate, and an arc-shaped block. The sliding frame is movably installed outside the crossbeam frame, and a sliding bolt is embedded in the side wall of the sliding frame. A buffer spring is fixedly connected to one side of the sliding frame, and one end of the buffer spring is fixedly connected to the inner side wall of the fixed seat. An arc-shaped plate is fixedly connected to one side of the sliding frame, and an arc-shaped block is fixedly connected to the inner surface of the arc-shaped plate. The shape and size of the arc-shaped block match the shape and size of the slot.

[0016] Furthermore, the specific steps of the leveling method are as follows:

[0017] A. Using pile driving equipment, a high-density pile is driven into the upper soil layer with high additional stress. Then, the control box and locking components are placed above the pile. The second handle is held and rotated. The second handle controls the rotation of the bidirectional screw rod. With the help of the sliding button and the trajectory restriction of the limit groove, the rotation of the bidirectional screw rod can drive the two moving blocks to move towards each other, thereby driving the two locking components to move horizontally in the center until the arc-shaped block is locked into the inside of the slot.

[0018] B. Hold the fixed seat and pull it upwards. The rotation of the fixed seat will compress the sliding frame, and the buffer spring will contract accordingly. This will allow the arc plate to fit tightly against the outside of the pile body, and the arc block to fit tightly into the inside of the slot, thus completing the position locking and fixing the control box to the top of the pile body.

[0019] C. The connector and mounting bracket are supported and fixed directly above the control box by the support assembly. The support assembly consists of a support column, a chassis and a support rod. The support rod enhances the connection between the support column and the chassis. The triangular support improves stability and increases the load-bearing points. The chassis increases the contact area to distribute the pressure on the foundation.

[0020] D. Hold the box and rotate it. Control the metal screw to rotate along the inner wall of the threaded pipe through the first handle. Under the restriction of the trajectory of the limit slide rail and the limit slider, the lifting frame can move down with the rotation of the metal screw, thereby driving the connecting rod and the mounting bracket connected to its bottom end to descend, so as to adjust the height of the tape measure until the connecting hook connected to the end of the tape measure can just hook into the tape measure.

[0021] E. As the pile gradually sinks, it will cause the metal ring to move downwards, thereby pulling the measuring tape down. The measuring tape reading is then read by the identification device. The measuring tape data represents the settlement of the pile. After a period of settlement, if the settlement of the pile exceeds or falls below the expected range, the identification device will send the read data to the construction personnel via wireless signal. The construction personnel will then adjust the foundation in the area where the pile is located to complete the leveling.

[0022] This invention provides a leveling device and method for composite foundations with long and short piles, which has the following beneficial effects:

[0023] 1. The present invention is provided with a support assembly, which consists of a support column, a base and a support rod. The support rod enhances the connection between the support column and the base, the triangular support improves stability and increases the load-bearing points. In addition, the base increases the contact area to distribute the pressure on the foundation. The improved leveling device can reduce the impact of its own downward pressure on the foundation leveling, reduce the impact of the device on the foundation during use, and help improve the accuracy of the leveling results.

[0024] 2. The present invention is equipped with an adjustment component. The metal screw is controlled to rotate along the inner wall of the threaded pipe by the first handle. Under the trajectory restriction of the limiting slide rail and the limiting slider, the lifting frame can be raised and lowered with the rotation of the metal screw, thereby driving the connecting rod and the mounting frame connected to its bottom end to be raised and lowered, so as to adjust the height of the measuring tape. The improved leveling device can adjust itself according to the position of the top of the pile body to improve the applicability of the device so that it can be used for piles with different burial depths.

[0025] 3. The present invention is equipped with a control box, which controls the rotation of the bidirectional lead screw through the second handle. With the help of the sliding button and the trajectory restriction of the limiting slide groove, the rotation of the bidirectional lead screw can drive the two moving blocks to move towards or away from each other, thereby driving the two locking components to translate and adjust their spacing. This makes the locking components suitable for clamping piles of more diameters. The improved leveling device has stronger applicability and can be used for piles of various sizes, so as to better suit the leveling operation of composite foundations with various pile lengths and lengths.

[0026] 4. The present invention is equipped with a locking component. The locking component is controlled by the control box to move horizontally, so that the arc-shaped block is inserted into the inner side of the slot to clamp the pile body. The position of the arc-shaped plate and the arc-shaped block is locked by moving the fixing seat, so that the locking component can stably clamp the pile body. The improved leveling device is easy to assemble and disassemble quickly, simple to operate and convenient to use, which can save a lot of time and improve the leveling and testing efficiency of composite foundations of long and short piles.

A threaded sleeve 2 is fixedly connected to the bottom of the fixed frame 1, and a support assembly 3 is threadedly connected to the inner side of the threaded sleeve 2. The support assembly 3 includes a support column 301, a base 302, and a support rod 303.

The support column 301, base 302, and support rod 303 form an integrated structure, with the support rod 303 reinforcing the support column. The connection between support column 301 and chassis 302 is effective, and the combined use of support column 301, chassis 302 and support rod 303 disperses the pressure on the foundation, reducing the impact of the device on the foundation during use. A connector 4 is fixedly connected to one side of the mounting bracket 1, and an adjustment component 5 is fixedly connected to the inner surface of the connector 4. The adjustment component 5 includes a housing 501, a limiting slide rail 502, a first bearing 503, a metal screw 504, and a first rotary handle 505. The limiting slide rail 502 is fixedly connected to the inner side wall of the housing 501, and the first bearing 503 is fixedly connected to the inner bottom wall of the housing 501. The metal screw 504 is fixedly connected to the inner wall of the first bearing 503, and a first rotary handle 505 is fixedly connected to the top of the metal screw 504. The exposed first handle 505 facilitates external control and adjustment of the housing 501. The adjustment assembly 5 also includes a threaded tube 506 and a lifting frame 507. The threaded tube 506 is sleeved on the outside of the lead screw 504, and its inner wall is threadedly connected to the inner wall of the lead screw 504. The lifting frame 507 is fixedly connected to the outer wall of the threaded tube 506. The threaded tube 506 and the lifting frame 507 form an embedded structure. Through the cooperation of the lead screw 504 and the threaded tube 506, the lead screw 504 can be driven to rotate along the inner wall of the threaded tube 506 to control the lifting frame 507. The adjustment assembly 5 also includes a limit slider 508 and a connecting rod 509, with the limit slider 508 fixedly mounted... The lifting frame 507 is mounted on both sides of the lifting frame 507. The lifting frame 507 forms a sliding structure with the limiting slide rail 502 via the limiting slider 508. The bottom of the lifting frame 507 is fixedly connected to the connecting rod 509, and the bottom end of the connecting rod 509 is welded to the top of the mounting frame 6.

The bottom of the adjusting component 5 is connected to the mounting frame 6, and the inner side of the mounting frame 6 is fixedly installed with an identification device 7 and a measuring tape 8. The end of the measuring tape 8 is fixedly connected with a connecting hook 9.

[0037] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the control box 10 is located directly below the mounting bracket 6. The control box 10 includes a housing 1001, a limiting slide groove 1002, a second bearing 1003, a double-acting lead screw 1004, and a second handle 1005. The limiting slide groove 1002 is formed on the top of the housing 1001, and the second bearing 1003 is fixedly installed on the inner wall of the housing 1001. The double-acting lead screw 1004 is fixedly connected to the inner wall of the second bearing 1003, and the second handle 1005 is fixedly connected to the end of the double-acting lead screw 1004. The exposed design of the second handle 1005 facilitates control and adjustment operations from outside the housing 1001. The control box 10 also includes a limiting plate 1006 and a movable... The control box 10 comprises a block 1007, a sliding button 1008, and a connecting seat 1009. A limiting plate 1006 is fitted onto the outer wall of the bidirectional lead screw 1004. A movable block 1007 is threadedly connected to the outer wall of the bidirectional lead screw 1004. A sliding button 1008 is fixedly connected to the top of the movable block 1007, and a connecting seat 1009 is fixedly connected to the bottom of the movable block 1007. The bottom of the connecting seat 1009 is fixedly connected to the top of the locking assembly 12. By rotating the bidirectional lead screw 1004, the two movable blocks 1007 can be controlled to move towards or away from each other, thereby adjusting the distance between the two locking assemblies 12 to accommodate clamping operations of piles 13 with larger diameters. A metal ring is welded to the top of the control box 10. 11. A locking assembly 12 is fixedly installed at the bottom of the control box 10. The locking assembly 12 includes a fixed base 1201, a wrench 1202, a crossbeam frame 1203, and a side slide groove 1204. The wrench 1202 is connected to the inner side of the fixed base 1201 via a pivot, and the crossbeam frame 1203 is fixedly connected to the inner side wall of the fixed base 1201. The outer wall of the crossbeam frame 1203 has a side slide groove 1204. The locking assembly 12 also includes a sliding frame 1205, a sliding bolt 1206, a buffer spring 1207, an arc plate 1208, and an arc block 1209. The sliding frame 1205 is movably installed outside the crossbeam frame 1203, and the side wall of the sliding frame 1205 is embedded with... There is a sliding bolt 1206, and a buffer spring 1207 is fixedly connected to one side of the sliding frame 1205. At the same time, one end of the buffer spring 1207 is fixedly connected to the inner side wall of the fixed seat 1201. An arc plate 1208 is fixedly connected to one side of the sliding frame 1205, and an arc block 1209 is fixedly connected to the inner surface of the arc plate 1208. The shape and size of the arc block 1209 match the shape and size of the slot 14. By inserting the arc block 1209 into the inner side of the slot 14, the connection effect between the arc plate 1208 and the pile 13 is enhanced, and the pile 13 can be stably clamped. The inner side of the locking component 12 is connected to the pile 13, and the surface of the pile 13 is provided with a slot 14.

[0038] In summary, combining Figures 1-7 As shown, the leveling method for the leveling device used in the composite foundation of long and short piles is as follows:

[0039] A. Using pile driving equipment, a pile body 13 with a larger density is driven into the upper soil layer with greater additional stress. Then, the control box 10 and the locking component 12 are placed above the pile body 13. The second handle 1005 is rotated by hand. The second handle 1005 controls the rotation of the bidirectional screw 1004. With the trajectory restriction of the sliding button 1008 and the limiting slide groove 1002, the rotation of the bidirectional screw 1004 can drive the two moving blocks 1007 to move towards each other, thereby driving the two locking components 12 to move horizontally in the center until the arc block 1209 is inserted into the inside of the slot 14.

[0040] B. Hold the fixed base 1201 and pull it upward. The rotation of the fixed base 1201 will compress the sliding frame 1205, and the buffer spring 1207 will contract accordingly. This will allow the arc plate 1208 to fit tightly against the outside of the pile body 13, and the arc block 1209 to fit tightly into the inside of the slot 14, thus completing the position locking and fixing the control box 10 to the top of the pile body 13.

[0041] C. The connector 4 and the mounting bracket 6 are supported and fixed directly above the control box 10 by the support assembly 3. The support assembly 3 consists of a support column 301, a chassis 302 and a support rod 303. The support rod 303 enhances the connection between the support column 301 and the chassis 302, improves stability by using triangular support, and increases the load-bearing points. In addition, the chassis 302 increases the contact area so that the device can distribute the pressure on the foundation.

[0042] D. Hold the box 501 and rotate it. Control the metal screw 504 to rotate along the inner wall of the threaded tube 506 through the first handle 505. Under the trajectory restriction of the limit slide rail 502 and the limit slider 508, the lifting frame 507 can move down with the rotation of the metal screw 504, thereby driving the connecting rod 509 and the mounting bracket 6 connected to its bottom end to descend, so as to adjust the height of the tape measure 8 until the connecting hook 9 connected to the end of the tape measure 8 can just hook into the tape measure 8.

[0043] E. As the pile 13 gradually sinks, it will cause the metal ring 11 to move downwards, thereby pulling the measuring tape 8 downwards. The measuring tape value is read by the identification device 7. The measuring tape data is the settlement amount of the pile 13. After a period of settlement, if the settlement amount of the pile 13 exceeds or falls below the expected value range, the identification device 7 will send the read data to the construction personnel via wireless signal. The construction personnel will then adjust the foundation in the area where the pile 13 is located to complete the leveling.

[0044] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.

9. A leveling method for a leveling device for a composite foundation of long and short piles according to claim 8, characterized in that, The specific steps of the leveling method are as follows: A. Using a pile driving device, a pile body (13) with a larger density is driven into the upper soil layer with greater additional stress. Then, the control box (10) and the locking component (12) are placed above the pile body (13). The second handle (1005) is held and rotated. The second handle (1005) controls the rotation of the bidirectional screw (1004). With the trajectory restriction of the sliding button (1008) and the limiting slide groove (1002), the rotation of the bidirectional screw (1004) can drive the two moving blocks (1007) to move towards each other, thereby driving the two locking components (12) to move in the center until the arc block (1209) is inserted into the inside of the slot (14). B. Hold the fixed seat (1201) and pull it upward. The rotation of the fixed seat (1201) will compress the sliding frame (1205), and the buffer spring (1207) will contract accordingly, so that the arc plate (1208) can fit tightly against the outside of the pile body (13), and the arc block (1209) can fit tightly into the inside of the slot (14) to complete the position locking and fix the control box (10) on the top of the pile body (13). C. The connector (4) and the mounting bracket (6) are supported and fixed directly above the control box (10) by the support assembly (3). The support assembly (3) consists of a support column (301), a chassis (302) and a support rod (303). The support rod (303) enhances the connection between the support column (301) and the chassis (302), improves stability by using triangular support, and increases the load-bearing points. In addition, the chassis (302) increases the contact area so that the device can distribute the pressure on the foundation. D. Hold the box (501) and rotate it. Control the metal screw (504) to rotate along the inner wall of the threaded tube (506) through the first handle (505). Under the trajectory restriction of the limiting slide rail (502) and the limiting slider (508), the lifting frame (507) can move down with the rotation of the metal screw (504), thereby driving the connecting rod (509) and the mounting bracket (6) connected to its bottom end to descend, so as to adjust the height of the tape measure (8) until the connecting hook (9) connected to the end of the tape measure (8) can just hook into the metal ring (11). E. As the pile (13) gradually sinks, it will drive the metal ring (11) to move downward, thereby pulling the tape measure (8) down. The tape measure value is read by the identification device (7). The tape measure data is the settlement of the pile (13). After a period of settlement, if the settlement of the pile (13) exceeds or falls below the expected value range, the identification device (7) will send the read data to the construction personnel via wireless signal. The construction personnel will then adjust the foundation of the area where the pile (13) is located to complete the leveling.
