Description

Technical Field

[0001] This utility model relates to the field of support pile technology, specifically a combined deep foundation pit waterproof support pile. Background Technology

[0002] Support piles play a crucial role in the design and construction of deep foundation pit support systems. Their main functions include: preventing soil collapse to ensure the safety of construction workers; resisting groundwater pressure to prevent soil erosion within the foundation pit; and maintaining the overall stability of the foundation pit. Traditional support piles are usually directly inserted into the foundation pit; however, due to the pressure of the soil or water, the stability of the support piles is insufficient.

[0003] To address the aforementioned issues, Chinese patent CN212714909U proposes an innovative prestressed concrete retaining pile structure for walls. This retaining pile consists of a pile body and a conical pile head. The pile body has a through hole and is evenly distributed with several prestressed steel bars to enhance its structural strength. The upper side of the pile body has a first connecting groove, while the outer wall has two sets of connecting protrusions evenly distributed, namely a first connecting protrusion and a second connecting protrusion. The first connecting protrusion includes a first rectangular pre-reserved hole, with trapezoidal protrusions symmetrically arranged on both sides; the second connecting protrusion has a second rectangular pre-reserved hole, with trapezoidal grooves symmetrically opened on both sides to match the trapezoidal protrusions. A connecting ring is fixedly installed on the lower side of the pile body, and the conical pile head has a second connecting groove matching the connecting ring. This patent, through the cooperative use of the first and second connecting protrusions, enables more flexible and tighter assembly between retaining piles, improving the tightness between retaining piles, and ensuring that the piles are properly assembled after all retaining piles are in place.

[0004] This existing technology, through the cooperative use of a first connecting protrusion and a second connecting protrusion, achieves flexible and tight assembly between support piles, significantly improving the tightness between them. However, as the splicing height of the support piles increases, their connection stability gradually decreases, making the support piles prone to tilting and causing the upper support piles to fall, posing a certain safety hazard. Utility Model Content

[0005] The purpose of this invention is to provide a combined deep foundation pit waterproof support pile. By splicing the support piles together, a second support sleeve and a second screw are inserted between two sets of upper and lower plug joints to enhance the stability of adjacent support pile bodies. Simultaneously, a connector is used to tightly connect adjacent support pile bodies on the left and right sides, further improving the stability of adjacent support pile bodies on the left and right sides.

[0006] To address the existing technical problems, this utility model provides a combined deep foundation pit waterproof support pile, including a support pile body, a support column, and a pile head. Two connecting sleeves are provided on one side of the support pile body, and the two connecting sleeves are symmetrical with respect to the center position of the support pile body. The connecting sleeves are provided with plug joints. A connecting device for connecting two longitudinally adjacent sets of support pile bodies is provided. A slider is provided in the longitudinal position of the support pile body, and a groove is opened on the support pile body away from the slider. When two laterally adjacent support pile bodies are spliced, the slider on one support pile body is inserted into the groove of the other support pile body.

[0007] Preferably, the connecting device includes a second support sleeve, one end of which is movably connected to a second screw via a thread, one end of which is inserted into a connector on the lower support pile body and fixed with bolts, and one end of the second support sleeve is inserted into a connector on the upper support pile body and fixed with bolts.

[0008] Preferably, the groove is further provided with a waterproof pad for filling the gap between the groove and the slider.

[0009] Preferably, two adjacent support piles in the lateral direction are connected by bolts to a connector. The connector is also provided with a connector for installing scaffolding. There are three connectors, and the three connectors are distributed around the connector as the center.

[0010] Preferably, the bottom of the support pile body is provided with external threads, and the inside of the pile head is provided with internal threads, and the external threads of the support pile body and the internal threads inside the pile head mesh with each other.

[0011] Preferably, a first support sleeve is connected to one side of the support column, and the inner wall of the first support sleeve is provided with an internal thread, and the outer side of the first screw is provided with an external thread. The internal thread of the first support sleeve and the external thread of the first screw mesh with each other, and the first screw is inserted into the connector on the lower connector.

[0012] Preferably, the bottom of the pile head is conical.

[0013] Preferably, the waterproof pad is a rubber pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the combined deep foundation pit waterproof support pile structure is reasonable and has the following advantages:

[0015] (1) This application enhances the structural stability of the upper and lower sets of support pile bodies by splicing the upper and lower support pile bodies together and inserting the second support sleeve and the second screw between the upper and lower sets of plug joints. At the same time, the left and right adjacent support pile bodies are connected with the connector, which further improves the stability of the left and right adjacent support pile bodies.

[0016] (2) This application also includes a support column with a first support sleeve connected to it. By rotating, the first screw can be unscrewed from the first support sleeve and inserted into the connector on the connector near the bottom of the foundation pit. At the same time, other connectors can be connected to scaffolding. When the support pile body is arranged around the foundation pit, the scaffolding can provide the necessary support force for the support pile body, effectively preventing the support pile body from tilting due to soil compression.

[0017] (3) This application incorporates a waterproof pad in the slide groove. The waterproof pad has a certain degree of elasticity, and when the slider is inserted into the slide groove, the waterproof pad can fill the tiny gap between the slide groove and the slider, thereby achieving an effective waterproof function.

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] Reference Figures 1-7 As shown, this utility model provides a combined deep foundation pit waterproof support pile, including a support pile body 1, a support column 3, and a pile head 11, the bottom of which is conical. The pile head 11, as the primary part of the support pile in contact with the foundation pit ground, optimizes the insertion performance of the pile head 11, allowing it to penetrate more easily and be firmly inserted into the foundation pit ground. Two connecting sleeves 12 are provided on one side of the support pile body 1, and the two connecting sleeves 12 are symmetrical with respect to the center position of the support pile body 1. A plug-in joint 13 is provided on the connecting sleeve 12. A connecting device is provided between longitudinally adjacent support pile bodies 1 for connection. When longitudinally adjacent support pile bodies 1 are spliced, they are connected by a special connecting device, ensuring the tightness and stability between the support pile bodies 1. A slider 14 is provided in the longitudinal position on the support pile body 1, and a groove 15 is provided on the support pile body 1 away from the slider 14. When two support pile bodies 1 that are laterally adjacent are spliced ​​together, the slider 14 on one support pile body 1 is inserted into the groove 15 of the other support pile body 1. The splicing method of slider 14 and groove 15 not only simplifies the installation process of the support pile, but also improves the integrity and stability of the support structure.

[0028] This combined deep foundation pit waterproof support pile achieves efficient and stable foundation pit support by optimizing the pile head 11 design, strengthening the structure of the support pile body 1, setting connecting sleeves 12 and plug joints 13, and adopting a splicing method of sliders 14 and grooves 15. This system not only improves the bearing capacity and stability of the support pile body 1, but also simplifies the installation process, reduces construction costs, and provides a reliable support solution for deep foundation pit projects.

[0029] The connecting device includes a second support sleeve 4, one end of which is threadedly connected to a second screw 41. One end of the second screw 41 is inserted into a connector 13 on the lower support pile body 1 and fixed with bolts. The other end of the second support sleeve 4 is inserted into a connector 13 on the upper support pile body 1 and fixed with bolts. The use of the second support sleeve 4 and the second screw 41 improves the connection stability and load-bearing capacity between the support pile bodies 1.

[0030] The groove 15 is also equipped with a waterproof gasket 151 for filling the gap between the groove 15 and the slider 14. The waterproof gasket 151 is a rubber gasket. The rubber gasket has good elasticity and sealing performance, which can effectively fill the gap between the groove 15 and the slider 14, preventing moisture and impurities from seeping into the interior of the support structure. This enhances the waterproof performance of the support pile.

[0031] Two adjacent horizontal support piles 1 are externally connected by bolts to a connector 2. The connector 2 is also equipped with a connector head 21 for installing scaffolding. There are three connector heads 21, which are distributed around the connector 2. The scaffolding can be inserted into the connector head 21, providing a safe and reliable working platform for construction workers, while also providing additional support.

[0032] The bottom of the support pile body 1 is provided with external threads, and the inside of the pile head 11 is provided with internal threads. The external threads of the support pile body 1 and the internal threads inside the pile head 11 mesh with each other. This threaded connection method not only improves the stability and reliability of the connection, but also facilitates the disassembly and replacement of the pile head 11.

[0033] A first support sleeve 31 is connected to one side of the support column 3, and an internal thread is provided on the inner wall of the first support sleeve 31. An external thread is provided on the outside of the first screw 32. The internal thread of the first support sleeve 31 and the external thread of the first screw 32 mesh with each other, and the first screw 32 is inserted into the connector 21 on the lower connector 2.

[0034] The first screw 32 is connected to the connector 21, forming a more stable structural system. This connection method not only improves the overall bearing capacity of the support pile system, but also enhances its resistance to lateral forces and overturning, thereby ensuring the safety and stability of deep foundation pit engineering.

[0035] Working Principle: First, the support pile body 1 is inserted into the foundation pit, and multiple support pile bodies 1 are spliced ​​together. During splicing, the cooperation between the slider 14 and the groove 15 is used to achieve the lateral connection between the support pile bodies 1. A waterproof pad 151 is provided inside the groove 15. When the slider 14 is fully inserted into the groove 15, the waterproof pad 151 can effectively fill the tiny gap between the groove 15 and the slider 14, thereby ensuring the waterproof performance between the support pile bodies 1. Subsequently, the left and right adjacent support pile bodies 1 are connected by the connector 2 to enhance the overall stability of the support pile bodies 1. At the same time, the upper and lower sets of support pile bodies 1 are connected by the second support sleeve 4 and the second screw 41 to further increase the stability between the upper and lower sets of support pile bodies 1. In addition, this combined support pile is also provided with a support column 3, and a first support sleeve 31 is connected to the support column 3. In use, the first screw 32 is unscrewed from the first support sleeve 31 and inserted into the connector head 21 on the connector 2 near the bottom of the foundation pit. Meanwhile, other connectors 21 can be used to insert scaffolding. When the support pile body 1 is arranged around the foundation pit, the scaffolding can provide additional support for the support pile body 1, effectively preventing the support pile body 1 from tilting due to soil compression, thereby ensuring the stability and safety of the entire support structure.
