Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a hybrid pile structure and construction method that combines slope pile foundation and foundation pit support pile. Background Technology

[0002] Excavation pit support refers to the measures taken to support, reinforce, and protect the sidewalls and surrounding environment of an excavation pit to ensure the safety of underground structure construction and the surrounding environment. In building construction, municipal pipeline laying, and subway construction, it is often necessary to excavate excavations of various sizes. To prevent soil collapse on the pit slopes, metal support devices are typically installed inside the pit.

[0003] However, existing foundation pit support devices still have the following significant shortcomings in actual construction applications, which urgently need to be improved: First, there is a lack of flexible overall span and local stress point adjustment capabilities. Existing support devices are mostly fixed-size welded frames, or only capable of simple unidirectional expansion and contraction. When facing foundation pits of varying widths or irregular shapes, it is not only difficult to quickly adapt the support span, but the position of the core support grid inside the pit is also usually fixed. This results in the inability to adjust the support components locally according to the actual soil pressure distribution on site, leading to poor versatility; on-site cutting or re-welding would severely delay the construction progress.

[0004] Secondly, the on-site assembly of the internal support frame is extremely cumbersome and inefficient. Traditionally, the horizontal and vertical support members inside the foundation pit are fixed using bolts through holes and tightened or direct welding. Because the bottom of the foundation pit is usually a confined space, poorly lit, and often muddy, aligning and tightening numerous bolt holes on-site is extremely time-consuming and labor-intensive for construction workers. This not only significantly reduces on-site assembly efficiency but also makes disassembly and pile extraction after project completion extremely difficult. Furthermore, rusted threads and mud can render components unusable, increasing construction costs.

[0005] In summary, existing foundation pit support devices are insufficient in terms of flexibility in size adjustment, seamless interception effect of slope support, and ease of on-site assembly, and cannot meet the needs of modern, efficient, and safe foundation pit construction. Summary of the Invention

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hybrid pile structure for both slope pile foundation and foundation pit support pile, comprising: a load-bearing base; a slope support plate slidably disposed at both ends of the load-bearing base; and a support pile base slidably disposed in the middle of the load-bearing base; a first sliding groove is respectively provided on both ends of the load-bearing base, and the bottom end of the slope support plate is inserted into the first sliding groove.

[0007] The technical effect of adopting the above-mentioned further solution is that by sliding the slope support plates at both ends of the load-bearing base and sliding the support pile base in the middle, the operator can flexibly adjust the initial position of the outer support and the internal support structure according to the width of the specific foundation pit and the internal stress requirements, thereby improving the versatility of the support device in foundation pits of different sizes.

[0008] In one preferred embodiment, the surface array of the load-bearing base is provided with multiple locking holes, and a second threaded rod is threaded through the slope support plate, with the bottom end of the second threaded rod inserted into the corresponding locking hole.

[0009] The technical effects of adopting the above-mentioned further solution are as follows: the guiding effect of the first sliding groove ensures the stability of the slope support plate during translation adjustment; by using the second threaded rod to cooperate with the array of locking holes on the load-bearing base, the slope support plate can be quickly locked and released in multiple positions, which is convenient to operate and has a reliable positioning.

[0010] In a preferred embodiment, a first threaded rod and a limiting rod are provided on the side of the slope support plate away from the center of the load-bearing base, and the extended ends of the first threaded rod and the limiting rod are connected to an H-shaped support plate.

[0011] The technical effect of adopting the above-mentioned further solution is that, with the help of the transmission of the first threaded rod, the lateral position of the H-shaped support plate can be finely adjusted outward, so that it can fit more closely to the slope of the foundation pit and enhance the actual support effect; at the same time, the limiting rod effectively prevents the force deflection of the H-shaped support plate during the outward pushing process, ensuring the flatness of the support surface.

[0012] In a preferred embodiment, concave plates and connecting strips are respectively fixed laterally on the inner sides of the two H-shaped support plates facing each other, and the connecting strip on one side is slidably inserted into the concave plate on the other side, and vertical strips are fixed vertically on the surface of the concave plate.

[0013] The technical effect of adopting the above-mentioned further solution is that the sliding insertion design of the connecting strip inside the concave plate allows the two to maintain a physical connection when adjusting the spacing of adjacent H-shaped support plates. Together with the vertical strip, they form a complete side wall interception surface, effectively preventing the slope soil from sliding or seeping out from the gaps opened by the support plates.

[0014] In a preferred embodiment, a second sliding groove is provided on the top surface of the middle part of the load-bearing base, and the bottom of the support pile base is embedded in the second sliding groove.

[0015] The technical effect of adopting the above-mentioned further solution is that the second chute provides a clear guide trajectory for the movement of the support pile base, so that the internal central support structure can be smoothly pushed on the load-bearing base to the required stress point at the bottom of the pit, which facilitates rapid positioning on the construction site.

[0016] In a preferred embodiment, a locking hole is provided on the side of the second sliding groove on the load-bearing base, and a third threaded rod is threaded through the side of the support pile base, with the bottom end of the third threaded rod inserted into the locking hole.

[0017] The technical effect of adopting the above-mentioned further solution is that after determining the specific position of the support pile base, by tightening the third threaded rod and inserting its bottom end into the side locking hole, the support pile base can be quickly fixed and limited, preventing it from sliding unexpectedly during subsequent construction operations or when bearing lateral earth pressure.

[0018] In one preferred embodiment, the top surface of the support pile base is provided with four square slots, and vertical plates are vertically inserted into each of the four square slots.

[0019] The technical advantages of adopting the above-mentioned further solution are: the square groove provides a stable mounting base for the vertical plate, and this plug-in matching method makes the assembly of the upper facade support structure more intuitive; at the same time, it is convenient to disassemble and separate the vertical plate during transportation and in non-working state, reducing the overall space occupied by the equipment and facilitating transportation.

[0020] In a preferred embodiment, a first round rod is horizontally inserted between the two vertical plates, and a round hole is provided on the vertical plate for the first round rod to pass through; a first magnet is embedded in the inner wall of the round hole, and a second magnet that is magnetically attracted to the first magnet is embedded in the end of the first round rod.

[0021] The technical effects of adopting the above-mentioned further solution are as follows: the first round rod connects the opposite vertical plates, which enhances the lateral structural strength of the internal frame; the fixation design of the first magnet and the second magnet attracting each other with opposite polarities eliminates the tedious process of aligning and tightening traditional bolts, and significantly improves the efficiency of on-site assembly and disassembly of the rods while ensuring the stability of the node connection.

[0022] In a preferred embodiment, a side strip is horizontally fixed between the two vertical plates, and a second round rod is horizontally inserted through the first round rod. An insertion hole is provided on the side strip, and the end of the second round rod is inserted into the insertion hole. The inner wall of the insertion hole is also embedded with the first magnet, and the end of the second round rod is also embedded with the second magnet.

[0023] The technical effect of adopting the above-mentioned further solution is that the second round rod and the first round rod are interlocked and inserted into the insertion hole of the side strip to construct a three-dimensional support grid with crisscrossing, which further improves the overall compressive and deformation resistance of the central support structure; at the same time, the magnetic attraction locking method of the first magnet and the second magnet is reused at the connection, which allows for quick disassembly and assembly without tools and improves work efficiency.

[0024] On the other hand, a construction method for a hybrid pile structure that combines slope pile foundations and foundation pit support piles: S1: The operator needs to loosen the second threaded rod so that its end can be dislodged from the pre-reserved locking hole of the load-bearing base. After the lock is released, the slope support plate can be moved horizontally along the guide track of the first slide groove. After the position is adjusted to the correct position, the second threaded rod is tightened again so that it is locked into the corresponding locking hole. The operator drives the first threaded rod and, with the guidance and anti-deflection cooperation of the limit rod, pushes the H-shaped support plate outward smoothly until it is firmly against the slope. During the process of adjusting the spacing or pushing outward of the H-shaped support plate, the connecting strip at its side end can slide smoothly inside the concave plate. S2: By tightening or loosening the third threaded rod, the operator can control the support pile base to slide freely or lock in the second groove. The vertical plate is inserted into the square groove at the top of the support pile base. Then, the first round rod is passed horizontally through the mounting holes on the vertical plate. The first magnet is pre-embedded in the hole of the vertical plate, and the second magnet is embedded in the inserted end of the first round rod. S3: When the rod is inserted into place, the two magnets of opposite polarities attract each other, instantly completing the anti-detachment limit of the rod. The second round rod passes through the first round rod and its end is guided into the insertion hole of the side strip. Similarly, the first magnet in the insertion hole attracts the second magnet at the end of the rod to fix it in place.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this embodiment of the invention, to adapt to different widths of foundation pits, the operator needs to loosen the second threaded rod so that its end can disengage from the pre-drilled hole in the load-bearing base. After unlocking, the slope support plate can be moved along the guide trajectory of the first sliding groove to quickly adjust the initial span of the support structure on both sides. After the position is adjusted, the second threaded rod is tightened again so that it is locked into the corresponding hole. To achieve a tighter mechanical fit between the support system and the sidewall of the foundation pit, the operator can drive the first threaded rod and, with the guidance and anti-deflection of the limit rod, smoothly push the H-shaped support plate outward until it is firmly against the slope. It is worth mentioning that during the spacing adjustment or outward pushing of the H-shaped support plate, the connecting strip at its side end can slide smoothly inside the concave plate; this pull-out plug-in design not only ensures the flexibility of telescopic adjustment, but also, combined with the structural reinforcement of the vertical strip, ensures that a complete dynamic interception surface is always maintained between adjacent support plates, effectively preventing the slope soil from sliding down.

[0026] 2. In this embodiment of the invention, the position of the core support grid inside the foundation pit can be flexibly arranged according to the actual stress requirements. By tightening or loosening the third threaded rod, the operator can control the support pile base to slide freely or lock in the second sliding groove, thereby greatly improving the adjustment efficiency of the support position inside the pit.

[0027] 3. In this embodiment of the invention, during the assembly of the upper support components, the vertical plate is first inserted into the square groove at the top of the support pile base, and the first round rod is sequentially inserted horizontally through the mounting holes on the vertical plate. A first magnet is pre-embedded in the hole of the vertical plate, and a second magnet is embedded in the inserted end of the first round rod. When the rod is inserted into place, the two magnets attract each other, instantly completing the anti-detachment and limiting of the rod. When assembling in a crisscross pattern, the second round rod is passed through the first round rod and its end is inserted into the insertion hole of the side strip. Similarly, the first magnet in the insertion hole attracts the second magnet at the end of the rod to fix it in place. This magnetic self-locking structure completely eliminates the cumbersome screw tightening process, ensuring the overall stability of the support frame while significantly shortening the on-site assembly and disassembly cycle.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 8 This embodiment provides a technical solution: a hybrid pile structure that combines slope pile foundation and foundation pit support pile, comprising: a load-bearing base 101; a slope support plate 103 slidably disposed at both ends of the load-bearing base 101; a support pile base 111 slidably disposed in the middle of the load-bearing base 101; and first sliding grooves 102 respectively opened on both ends of the load-bearing base 101, with the bottom end of the slope support plate 103 inserted into the first sliding groove 102.

[0032] In use, by sliding the slope support plate 103 at both ends of the load-bearing base 101 and sliding the support pile base 111 in the middle, the operator can flexibly adjust the initial position of the outer support and the internal support structure according to the width of the specific foundation pit and the internal stress requirements, which improves the versatility of the support device in foundation pits of different sizes.

[0033] like Figures 1 to 8 As shown, in one embodiment, the surface of the load-bearing base 101 is arrayed with multiple locking holes 116, and a second threaded rod 110 is threaded through the slope support plate 103. The bottom end of the second threaded rod 110 is inserted into the corresponding locking hole 116. Through the guiding action of the first sliding groove 102, the stability of the slope support plate 103 during translation adjustment is ensured. By using the second threaded rod 110 to cooperate with the array of locking holes 116 on the load-bearing base 101, the slope support plate 103 can be quickly locked and released in multiple positions, which is convenient to operate and has a reliable positioning.

[0034] like Figures 1 to 8As shown, in one embodiment, a first threaded rod 105 and a limiting rod 104 are provided on the side of the slope support plate 103 away from the center of the load-bearing base 101. The extended ends of the first threaded rod 105 and the limiting rod 104 are connected to an H-shaped support plate 106. With the transmission of the first threaded rod 105, the lateral position of the H-shaped support plate 106 can be slightly adjusted outward, so that it can fit more closely to the slope of the foundation pit and enhance the actual support effect. At the same time, the limiting rod 104 effectively prevents the force deflection of the H-shaped support plate 106 during the outward pushing process, ensuring the flatness of the support surface.

[0035] like Figures 1 to 8 As shown, in one embodiment, concave plates 108 and connecting strips 107 are respectively fixed laterally on the inner sides of the two H-shaped support plates 106 facing each other. The connecting strip 107 on one side is slidably inserted into the concave plate 108 on the other side. Vertical strips 109 are vertically fixed on the surface of the concave plate 108. The sliding insertion design of the connecting strip 107 inside the concave plate 108 allows the two to maintain a physical connection when adjusting the spacing between adjacent H-shaped support plates 106. Together with the vertical strips 109, they form a complete side wall interception surface, effectively preventing slope soil from sliding or seeping through the gaps opened by the support plates.

[0036] like Figures 1 to 8 As shown, in one embodiment, a second groove 122 is provided on the top surface of the middle part of the load-bearing base 101, and the bottom of the support pile base 111 is embedded in the second groove 122. The second groove 122 provides a clear guide trajectory for the movement of the support pile base 111, so that the internal central support structure can be smoothly pushed on the load-bearing base 101 to the required force point at the bottom of the pit, which facilitates quick positioning on the construction site.

[0037] like Figures 1 to 8 As shown, in one embodiment, a locking hole 116 is provided on the side of the second sliding groove 122 on the load-bearing base 101. A third threaded rod 115 is threaded through the side of the support pile base 111. The bottom end of the third threaded rod 115 is inserted into the locking hole 116. After determining the specific position of the support pile base 111, by tightening the third threaded rod 115 and inserting its bottom end into the locking hole 116 on the side, the support pile base 111 can be quickly fixed and limited to prevent it from sliding unexpectedly during subsequent construction operations or when subjected to lateral earth pressure.

[0038] like Figures 1 to 8As shown, in one embodiment, the top surface of the support pile base 111 is provided with four square slots 121, and vertical plates 112 are vertically inserted into the four square slots 121 respectively. The square slots 121 provide a stable mounting base for the vertical plates 112. This plug-in type of connection makes the assembly of the upper facade support structure more intuitive; at the same time, it is convenient to disassemble and separate the vertical plates 112 during transportation and in non-working states, reducing the overall space occupied by the equipment and facilitating transportation.

[0039] like Figures 1 to 8 As shown, in one embodiment, a first round rod 113 is horizontally inserted between two vertical plates 112. A round hole is provided on the vertical plate 112 for the first round rod 113 to pass through. A first magnet 119 is embedded in the inner wall of the round hole, and a second magnet 120 is embedded at the end of the first round rod 113, which is magnetically attracted to the first magnet 119. The first round rod 113 connects the opposing vertical plates 112, enhancing the lateral structural strength of the internal frame. The fixation design using the attraction between the opposite poles of the first magnet 119 and the second magnet 120 eliminates the cumbersome process of aligning and tightening traditional bolts, and significantly improves the efficiency of on-site assembly and disassembly of the rods while ensuring the stability of the node connection.

[0040] like Figures 1 to 8 As shown, in one embodiment, a side strip 117 is horizontally fixed between two vertical plates 112. A second round rod 114 is horizontally inserted through the first round rod 113. An insertion hole 118 is provided on the side strip 117, and the end of the second round rod 114 is inserted into the insertion hole 118. A first magnet 119 is also embedded in the inner wall of the insertion hole 118, and a second magnet 120 is also embedded in the end of the second round rod 114. The second round rod 114 and the first round rod 113 are cross-fitted and inserted into the insertion hole 118 of the side strip 117, thus constructing a crisscrossing three-dimensional support grid, which further improves the overall compressive and deformation resistance of the central support structure. At the same time, the magnetic locking method of the first magnet 119 and the second magnet 120 is reused at the connection, which allows for quick disassembly and assembly without tools, improving work efficiency.

[0041] Working principle: During use, the slope lateral support and span adjustment are performed as follows: To adapt to different widths of the foundation pit, the operator needs to loosen the second threaded rod (110) so that its end can be dislodged from the pre-drilled hole (116) in the load-bearing base (101). After unlocking, the slope support plate (103) can be moved along the guide trajectory of the first slide groove (102) to quickly adjust the initial span of the support structure on both sides. After the position is adjusted, the second threaded rod (110) is tightened again so that it is locked into the corresponding hole (116). In order to achieve a tighter mechanical fit between the support system and the side wall of the foundation pit, the operator can drive the first threaded rod (105) and, with the guidance and anti-deflection cooperation of the limit rod (104), smoothly push the H-shaped support plate (106) outward until it is firmly against the slope. During the process of adjusting the spacing or pushing outwards of the H-shaped support plate (106), the connecting strip (107) at its side end can slide smoothly inside the concave plate (108). Combined with the structural reinforcement of the vertical strip (109), it can also ensure that a complete dynamic interception surface is always maintained between adjacent support plates, effectively preventing the slope soil from sliding down.

[0042] Slip positioning and rapid assembly of support piles: By tightening or loosening the third threaded rod (115), the operator can control the support pile base (111) to slide freely or lock in the second slide groove (122), thereby greatly improving the adjustment efficiency of the support position in the pit.

[0043] When assembling the upper support components, the vertical plate (112) is first inserted into the square groove (121) at the top of the support pile base (111). Then, the first round rod (113) is inserted horizontally through the mounting holes on the vertical plate (112). The present invention adopts an innovative quick-release design for node connection: a first magnet (119) is pre-embedded in the hole of the vertical plate (112), and a second magnet (120) is embedded in the insertion end of the first round rod (113). When the rod is inserted into place, the two magnets attract each other, instantly completing the anti-dislodgement limit of the rod. Similarly, when crisscrossing, the second round rod (114) is inserted through the first round rod (113) and its end is inserted into the insertion hole (118) of the side strip (117). The first magnet (119) in the insertion hole is also used to attract and fix the rod end to the second magnet (120). This magnetic self-locking structure eliminates the cumbersome screw tightening process.

[0044] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields.
