Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, specifically to an interlocking pile structure for combined construction. Background Technology

[0002] With the development and utilization of urban underground space, the excavation depth of foundation pits is becoming increasingly deeper, and many foundation pit protection structures are located adjacent to the foundations of existing structures. Interlocking piles are a commonly used protective structure for urban foundation pits. Interlocking piles are a type of foundation pit retaining structure where piles interlock with each other. The piles are arranged alternately with one unreinforced plain concrete pile (Pile A) and one reinforced concrete pile (Pile B) (constructed using a full-casing drilling rig). During construction, pile A is constructed first, followed by pile B. Pile B is constructed after the initial setting of pile A but before its final setting. Both pile A and pile B are constructed using a full-casing drilling rig, cutting away the concrete at the intersection of adjacent pile A to achieve the interlocking effect.

[0003] Existing construction interlocking piles have poor positioning effect on the steel reinforcement binding structure of the interlocking pile column during the interlocking transition, resulting in poor maintenance of the vertical state of the pile column. Furthermore, the interlocking transition between adjacent pile columns cannot achieve a high degree of stability during the pouring process. Therefore, a combined construction interlocking pile structure is needed to improve the above problems. Summary of the Invention

[0004] To address the poor positioning effect of the steel reinforcement binding structure of interlocking piles during the pouring and transition of interlocking piles, and the inability to achieve a high degree of stability in the interlocking transition between adjacent piles during pouring, this invention provides a trenchless pipeline construction pipe jacking method to solve the above problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A composite construction interlocking pile structure includes a first construction pile column and a second construction pile column, wherein the first construction pile column and the second construction pile column are connected by a transition pile column.

[0007] The adjacent surfaces of the first and second construction piles are provided with pile engagement grooves. The transition piles are connected to the first and second construction piles respectively through the pile engagement grooves. Multiple sets of positioning cavities are evenly provided on the side walls of the pile engagement grooves of the first and second construction piles. The positioning cavities on the two side walls of the same pile engagement groove are connected by a support plate. Positioning holes are vertically provided on the first and second construction piles on the side closest to the pile engagement groove. Positioning shafts are installed inside the positioning holes. Positioning grooves are provided on the end faces of the first and second construction piles corresponding to the positioning holes. Fastening nuts are provided inside the positioning grooves corresponding to the positioning shafts.

[0008] The transition pile is constructed by casting a combination of vertical and circular reinforcing bars.

[0009] As a preferred embodiment of the present invention, a combined construction groove is provided on the side of the first construction pile and the second construction pile away from the transition pile, and the combined construction groove and the pile interlocking groove adopt the same structural configuration.

[0010] As a preferred embodiment of the present invention, the support plate is arranged in an arc shape, the support plate is adapted to and adjustable with the positioning cavity, and the two ends of the support plate are provided with connecting holes corresponding to the positioning shaft.

[0011] As a preferred embodiment of the present invention, the interior of the positioning groove is provided with a transition groove corresponding to the positioning hole, and the fastening nut is detachably rotatably connected to the transition groove.

[0012] As a preferred embodiment of the present invention, the fastening nut and the positioning shaft are connected by a corresponding threaded connection.

[0013] As a preferred embodiment of the present invention, the vertical reinforcing bar is fixed inside the annular reinforcing bar by binding wire, and the diameter of the annular reinforcing bar is slightly smaller than the central circle diameter of the pile interlocking groove.

[0014] In a preferred embodiment of the present invention, the annular steel bars and the supporting plate are arranged in a staggered manner.

[0015] As a preferred embodiment of the present invention, the vertical reinforcing bars are evenly laid on the inner side wall of the ring reinforcing bars, and the spacing between each vertical reinforcing bar is 8cm.

[0016] As a preferred embodiment of the present invention, the adjacent surfaces between the first construction pile and the second construction pile are connected by vertical reinforcing bars and ring reinforcing bars after pouring through pile interlocking grooves.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, the interlocking grooves between the first and second construction piles ensure a good interlocking connection between the transition pile and the first and second construction piles. Furthermore, the support plate within the interlocking groove supports and positions the reinforcing steel structure of the transition pile, resulting in high stability in the positioning and support of the transition pile. The reinforcing steel structure between the support plate and the transition pile also exhibits high stability during casting, leading to high interlocking stability between the transition pile and the first and second construction piles after casting. The tightening nut secures the positioning shaft, ensuring a stable connection between the positioning shaft and the first and second construction piles, and providing a good positioning connection between the positioning shaft and the support plate. The positioning groove allows for the concealment and storage of the tightening nut, better maintaining the flatness of the pile end face, thus improving the pile's performance during construction.

[0019] 2. In this invention, a combined construction groove is opened on the outer shell of the first and second construction piles. This combined construction groove improves the combined use effect of the first and second construction piles, resulting in better combined use during construction. The support plate adopts an arc-shaped structure, which allows for better support and positioning of the annular reinforcing bars, thus ensuring high support stability of the reinforcing steel structure of the transition pile. The connection hole on the support plate facilitates convenient and stable positioning and transition between the positioning shaft and the support plate. The detachable rotatable connection between the fastening nut and the transition groove makes the positioning operation of the positioning shaft of the fastening nut convenient and allows for positioning and transition between the fastening nut and the pile. This ensures good positioning effect of the fastening nut on the positioning shaft and high stability of the connection between the positioning shaft and the pile during construction.

[0020] 3. In this invention, by setting the diameter of the annular reinforcing bar slightly smaller than the central circle diameter of the pile interlocking groove, the concrete can better encapsulate the vertical reinforcing bars and the annular reinforcing bars during pouring, thus improving the pouring quality of the transition pile. The vertical reinforcing bars are evenly arranged inside the annular reinforcing bars, with a small spacing between each bar, resulting in higher strength of the transition pile and better interlocking and transitioning between the transition pile and the first and second construction piles. The staggered arrangement of the annular reinforcing bars and the support plate provides good limiting and supporting stability for the annular reinforcing bars, and ensures high connection stability between the transition pile and the first and second construction piles during pouring. This enhances the safety of the combined use of the transition pile, the first construction pile, and the second construction pile, effectively improving the quality of engineering construction.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Example: Please refer to Figure 1-9 The interlocking pile structure shown includes a first construction pile 1 and a second construction pile 2, and the first construction pile 1 and the second construction pile 2 are connected by a transition pile 3.

[0033] In this embodiment, reference is made to Figure 1-9As shown, pile engagement grooves 101 are provided on adjacent surfaces between the first construction pile 1 and the second construction pile 2. The transition pile 3 is connected to the first construction pile 1 and the second construction pile 2 respectively through the pile engagement grooves 101. Multiple sets of positioning cavities 102 are evenly provided on the side walls of the pile engagement grooves 101 of the first construction pile 1 and the second construction pile 2. The positioning cavities 102 on the two side walls of the same pile engagement groove 101 are connected by a support plate 103. Positioning holes 104 are vertically provided on the first construction pile 1 and the second construction pile 2, near the pile engagement grooves 101. Positioning shafts 105 are installed inside the positioning holes 104. Positioning grooves 106 are provided on the end faces of the first construction pile 1 and the second construction pile 2, corresponding to the positioning holes 104. Fastening nuts 107 are provided inside the positioning grooves 106, corresponding to the positioning shafts 105. The pile engagement grooves 101 provided on the first construction pile 1 and the second construction pile 2 enable the transition pile 3 to... The interlocking connection between the connecting pile 3 and the first construction pile 1 and the second construction pile 2 is good. Furthermore, the support plate 103 installed in the pile interlocking groove 101 can support and position the steel reinforcement structure of the connecting pile 3, thus ensuring high stability in the positioning and support of the connecting pile 3. Additionally, the steel reinforcement structure between the support plate 103 and the connecting pile 3 has high stability during pouring, resulting in high interlocking stability between the connecting pile 3 and the first construction pile 1 and the second construction pile 2 after pouring. The positioning nut 107 can securely position the positioning shaft 105, ensuring high stability in the connection between the positioning shaft 105 and the first construction pile 1 and the second construction pile 2. This provides a good positioning connection between the positioning shaft 105 and the support plate 103. The positioning groove 106 allows for the concealment and storage of the fastening nut 107, better maintaining the flatness of the pile end face and improving the pile's performance during construction.

[0034] The first construction pile 1 and the second construction pile 2 are provided with a combined construction groove 108 on the side away from the transition pile 3. The combined construction groove 108 and the pile engagement groove 101 adopt the same structure. The support plate 103 is arranged in an arc shape. The support plate 103 is adapted to the positioning cavity 102 and is adjustable. The two ends of the support plate 103 are provided with connecting holes 109 corresponding to the positioning shaft 105. The interior of the positioning groove 106 is provided with a transition groove 110 corresponding to the positioning hole 104. The fastening nut 107 is detachably rotatably connected to the transition groove 110. The fastening nut 107 is threadedly connected to the positioning shaft 105. A combined construction groove 108 is created on the outer shell of the first construction pile 1 and the second construction pile 2. This combined construction groove 108 improves the combined use effect of the first construction pile 1 and the second construction pile 2, resulting in better combined use during construction. The support plate 103, with its arc-shaped structure, better supports and positions the annular reinforcing steel 302, thus ensuring high support stability of the reinforcing steel structure of the transition pile 3. The 3 has a connecting hole 109, which makes the positioning and transfer between the positioning shaft 105 and the support plate 103 convenient and stable. The fastening nut 107 and the transfer groove 110 are detachably rotatably connected, which makes the positioning operation of the positioning shaft 105 by the fastening nut 107 convenient and allows the positioning transfer between the fastening nut 107 and the pile column. This makes the positioning effect of the fastening nut 107 on the positioning shaft 105 good and the connection between the positioning shaft 105 and the pile column highly stable during construction.

[0035] In this embodiment, reference is made to Figure 1 , 2As shown in Figures 3 and 4, the transition pile 3 is constructed by casting a combination of vertical reinforcing bars 301 and ring reinforcing bars 302. The vertical reinforcing bars 301 are fixed to the inner side of the ring reinforcing bars 302 using binding wire. The diameter of the ring reinforcing bars 302 is slightly smaller than the central circle diameter of the pile interlocking groove 101. The ring reinforcing bars 302 and the support plate 103 are arranged alternately. The vertical reinforcing bars 301 are evenly laid on the inner wall of the ring reinforcing bars 302, with a spacing of 8 cm between each vertical reinforcing bar 301. The adjacent surfaces of the first construction pile 1 and the second construction pile 2 are connected by the pile interlocking groove 101, where the vertical reinforcing bars 301 and ring reinforcing bars 302 are interlocked after casting. By setting the diameter of the annular steel bar 302 slightly smaller than the central circle diameter of the pile interlocking groove 101, the vertical steel bar 301 and the annular steel bar 302 can achieve better concrete encapsulation during pouring, thus ensuring good pouring quality of the transition pile 3. The vertical steel bars 301 are evenly arranged inside the annular steel bar 302, with a small spacing between each vertical steel bar 301, resulting in higher strength of the transition pile 3 and better interlocking and transitioning effect between the transition pile 3 and the first construction pile 1 and the second construction pile 2. The staggered arrangement of the annular steel bar 302 and the support plate 103 provides good limiting and supporting stability for the annular steel bar 302, and ensures high connection stability between the transition pile 3 and the first and second construction piles 1 and 2 during pouring. This enhances the safety of the combined use of the transition pile 3, the first construction pile 1, and the second construction pile 2, effectively improving the construction quality.

[0036] In this combined construction method, the interlocking pile structure involves using machinery to create the interlocking groove 101 in the pile column. After the interlocking groove 101 is created, auxiliary machinery is used to create corresponding positioning cavities 102 and positioning holes 104. The pile column formed by the vertical reinforcing bars 301 and the annular reinforcing bars 302 is supported by the interlocking groove 101. Then, multiple sets of support plates 103 are installed through the positioning cavity 102. After the support plates 103 are installed in accordance with the positioning cavity 102, the support plates 103 can be finely adjusted to align the connecting holes 105 on the support plates 103 with the positioning holes 104. Finally, the positioning shaft 105 is installed through the positioning holes 104, enabling the positioning shaft 105 to support multiple sets of... The two ends of the support plate 103 are fixed to limit the position, thus ensuring high stability of the support plate 103. The interlocking groove 101 between the first construction pile 1 and the second construction pile 2 ensures a good interlocking connection between the transition pile 3 and the first and second construction piles. Furthermore, the support plate 103 within the interlocking groove 101 supports and positions the reinforcing steel frame of the transition pile 3, resulting in high stability of the transition pile 3's position and support. Additionally, the reinforcing steel frame between the support plate 103 and the transition pile 3 exhibits high transition stability during pouring, leading to high interlocking stability between the transition pile 3 and the first and second construction piles 1 and 2 after pouring. When the positioning shaft 105 aligns with the positioning hole 104... After installation, the fastening nut 107 is connected to the positioning shaft 105, and the fastening nut 107 is also connected to the adapter groove 110, thereby achieving the tight fixing of the fastening nut 107 to the positioning shaft 105. The detachable rotatable connection between the fastening nut and the adapter groove makes the positioning operation of the positioning shaft by the fastening nut highly convenient, and allows for positioning and adapter between the fastening nut and the pile column. This ensures good positioning effect of the fastening nut on the positioning shaft and high stability of the connection between the positioning shaft and the pile column during construction. After completion, the pile column structure composed of vertical steel bars 301 and ring steel bars 302 is sealed with formwork, and then the vertical steel bars 301 and ring steel bars 302 are poured. This process achieves the formation of the transition pile 3, enabling an interlocking connection between the transition pile 3 and the first construction pile 1 and the second construction pile 2. Furthermore, by creating combination construction grooves 108 on other sides of the first and second construction piles 1 and 2, combined construction of multiple pile groups can be achieved, resulting in better combined use of the first and second construction piles 1 and 2 during construction. The arc-shaped structure of the support plate 103 allows for better support and positioning of the annular reinforcing steel 302, thus ensuring high stability of the reinforcing steel structure of the transition pile 3. The connecting holes 109 on the support plate 103 facilitate convenient and stable positioning and transition between the positioning shaft 105 and the support plate 103.The combined construction trench 108 enhances the applicability of the piles during construction, thereby effectively improving construction efficiency and quality.
