Description

Technical Field

[0001] This utility model relates to the field of foundation construction technology in building engineering, specifically a composite construction interlocking pile structure. Background Technology

[0002] In the field of foundation construction, interlocking pile structure is a key foundation pit support technology. It forms a solid underground wall through the interlocking of piles. It plays a vital role in the construction of many underground projects such as subway stations, underground parking lots, and basements of high-rise buildings. It can effectively resist soil pressure, prevent groundwater leakage, and ensure the safety and stability of the construction process and the surrounding environment.

[0003] Traditional interlocking pile structures have certain drawbacks during construction. Due to the complex and varied geological conditions at construction sites, and the different requirements for the dimensional accuracy of interlocking piles in different projects, it is difficult to make precise fine adjustments to existing interlocking pile structures once the design dimensions are determined. For example, when there are slight differences in the soil strata, and it is necessary to make minor adjustments to the diameter of the pile body, the interlocking width, and other dimensions to achieve the best support effect, conventional interlocking pile structures are difficult to implement. This not only affects the support performance of the interlocking pile structure, but may also lead to increased construction difficulty, extended construction period, and increased costs due to dimensional mismatch. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an interlocking pile structure for combined construction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined construction interlocking pile structure, comprising pile body one and pile body two, each pile body one and pile body two having a T-shaped clamp inserted inside, the outer surface of the T-shaped clamp having a movable groove one, the outer surface of the T-shaped clamp having a movable groove two, one of the T-shaped clamps having a tension plate one fixedly connected to the outer surface of the outer surface of the other T-shaped clamp, and the tension plate two being inserted into the tension plate one, an adjustment component being provided on the side of the tension plate one and tension plate two that are close to each other, and a fixing component being provided inside the movable groove one.

[0006] Furthermore, the adjustment assembly includes a threaded cylinder fixedly connected to the inner wall of the tensioning plate, a guide rod inserted into the inner wall of the threaded cylinder, a threaded post fixedly connected to the outer surface of the guide rod, and the end of the threaded post away from the threaded cylinder being fixedly connected to the inner wall of the tensioning plate.

[0007] Furthermore, the outer surface of the threaded cylinder is threadedly connected to a rotating cylinder, and the inner wall of the rotating cylinder is threadedly connected to the outer surface of the threaded column.

[0008] Furthermore, the fixing component includes a slide rod slidably connected to the inner wall of the T-shaped clip, one end of the slide rod is fixedly connected to a pull block, and the other end of the slide rod is fixedly connected to a limit piece.

[0009] Furthermore, the outer surface of the limiting piece is fixedly connected to a plug rod, and the outer surface of the plug rod is slidably connected to the inner wall of the T-shaped clip.

[0010] Furthermore, an elastic element is sleeved on the outer surface of the slide rod, one end of the elastic element is fixedly connected to the outer surface of the limiting piece, and the other end of the elastic element is fixedly connected to the inner wall of the movable groove.

[0011] Compared with existing technologies, the interlocking pile structure constructed using this combined method has the following advantages:

[0012] 1. This utility model facilitates the rapid connection between pile body one and pile body two by setting up a T-shaped clip, tension plate one, tension plate two, and fixing components. By setting up an adjustment component, the mutual distance between tension plate one and tension plate two can be finely adjusted. Through the cooperation of the T-shaped clip, tension plate one, tension plate two, fixing components, tension plate one, and tension plate two, the dimensions between pile body one and pile body two can be precisely finely adjusted to adapt to different geological conditions and engineering requirements.

[0013] 2. This utility model, by setting a sliding block, a limiting plate, an insert rod, and an elastic element, allows the limiting plate to compress the elastic element when the sliding block is pulled, causing the elastic element to deform and store a certain amount of elastic potential energy. After the force applied to the pulling block is released, the compressed elastic element can release its elastic potential energy, causing the sliding block, the limiting plate, and the insert rod to move rapidly in one direction, thereby achieving the effect of rapid reset of the sliding block, the limiting plate, and the insert rod.

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] This embodiment provides a combined construction interlocking pile structure. This utility model facilitates rapid connection between pile body 1 and pile body 2 by setting up a T-shaped clamp 3, a tension plate 1 6, a tension plate 2 7, and a fixing component 9. The adjustment component 8 allows for fine-tuning of the distance between tension plate 1 6 and tension plate 2 7. Through the coordinated use of the T-shaped clamp 3, tension plate 1 6, tension plate 2 7, fixing component 9, tension plate 1 6, and tension plate 2 7, precise micro-adjustment of the dimensions between pile body 1 and pile body 2 can be achieved to adapt to different geological conditions and engineering requirements.

[0021] See Figures 1-4 A composite construction interlocking pile structure includes pile body 1 and pile body 2. Pile body 1 and pile body 2 are typically made of high-strength reinforced concrete. Each of them has a T-shaped clamp 3 inserted inside. The T-shaped clamp 3 is made of high-quality carbon steel and has an ingenious shape design. The "T"-shaped head and rod can ensure stable insertion inside the pile body and will not easily displace. The outer surface of the T-shaped clamp 3 has movable groove 1 4 and movable groove 2 5. Movable groove 1 4 and movable groove 2 5 can provide installation and movement space for fixing components 9, ensuring that each component can slide smoothly in the groove, which facilitates the fixing effect of the T-shaped clamp 3.

[0022] One of the T-shaped clips 3 has a tension plate 6 fixedly connected to its outer surface, and another T-shaped clip 3 has a tension plate 7 fixedly connected to its outer surface. The tension plate 7 is inserted into the tension plate 6. The tension plates 6 and 7 can be made of alloy steel plates with high strength and toughness. The interlocking design allows the two to work together when adjusting the pile spacing, so as to evenly transmit the adjustment force to the T-shaped clip 3, thereby driving the pile 1 and pile 2 to move, ensuring the accuracy and stability of the pile spacing adjustment, and effectively avoiding structural deformation or damage caused by uneven local stress.

[0023] An adjustment component 8 is provided on the side of tension plate 6 and tension plate 7 that are close to each other.

[0024] The adjusting assembly 8 includes a threaded cylinder 801 fixedly connected to the inner wall of the tensioning plate 6. The inner wall of the threaded cylinder 801 is threaded and is made of high-strength alloy steel, which can withstand large torque without deformation.

[0025] A guide rod 802 is inserted into the inner wall of the threaded cylinder 801. The guide rod 802 is made of smooth stainless steel. A threaded post 803 is fixedly connected to its outer surface. The end of the threaded post 803 away from the threaded cylinder 801 is fixedly connected to the inner wall of the tension plate 7. The threaded post 803 is also made of high-strength alloy steel and matches the thread of the threaded cylinder 801. A rotating cylinder 804 is threadedly connected to the outer surface of the threaded cylinder 801. The rotating cylinder 804 has anti-slip texture on its outside to facilitate rotation. Its inner wall is threadedly connected to the outer surface of the threaded post 803.

[0026] By rotating the rotating cylinder 804, the threaded cylinder 801 and the threaded column 803 can move relative to each other using the transmission principle between the threads. This allows for precise adjustment of the distance between the tension plate 6 and the tension plate 7, enabling fine-tuning of the dimensions between pile 1 and pile 2 to adapt to different geological conditions and engineering requirements. For example, in soft soil layers, the pile spacing can be appropriately reduced to enhance overall stability, while in hard soil layers, the pile spacing can be appropriately increased as needed to optimize engineering costs and construction efficiency.

[0027] The interior of the active slot 4 is equipped with a fixing component 9.

[0028] The fixing component 9 includes a slide rod 901 that is slidably connected to the inner wall of the T-shaped clip 3. The slide rod 901 is made of high-strength aluminum alloy with a smooth surface to ensure low friction when sliding on the inner wall of the T-shaped clip 3.

[0029] One end of the slide bar 901 is fixedly connected to a pull block 902. The pull block 902 is designed to facilitate operation by construction personnel. For example, it has grooves or protrusions to increase the friction between the hand and the pull block 902.

[0030] The other end of the slide bar 901 is fixedly connected to a limiting piece 903. The size of the limiting piece 903 is slightly larger than the diameter of the slide bar 901 to prevent the slide bar 901 from coming out of the T-shaped clip 3.

[0031] The outer surface of the limiting piece 903 is fixedly connected to the insertion rod 904, which is made of a hard metal material, such as hardened steel. Its outer surface is slidably connected to the inner wall of the T-shaped clip 3. The length and diameter of the insertion rod 904 are precisely matched according to the pre-set insertion hole size on the pile body 1 and the pile body 2 to ensure accurate insertion and stable fixation.

[0032] An elastic element 905 is fitted on the outer surface of the slide bar 901. The elastic element 905 can be a spring made of high-strength spring steel. One end of the elastic element 905 is fixedly connected to the outer surface of the limiting piece 903, and the other end of the elastic element 905 is fixedly connected to the inner wall of the movable groove 4.

[0033] During construction, when the pull block 902 is pulled, causing the slide rod 901, the limiting plate 903, and the insertion rod 904 to move, the limiting plate 903 can compress the elastic element 905, thereby causing the elastic element 905 to deform and store a certain amount of elastic potential energy. After the force applied to the pull block 902 is released, the compressed elastic element 905 can release the elastic potential energy, causing the slide rod 901, the limiting plate 903, and the insertion rod 904 to move quickly in the opposite direction. This achieves the effect of rapid reset of the slide rod 901, the limiting plate 903, and the insertion rod 904, improving construction efficiency and ensuring the rapid installation and fixation of the interlocking pile structure during construction.

[0034] Working principle: During construction, pile 1 and pile 2 are initially positioned by inserting T-shaped clips 3 into their respective interiors. During this process, the pull block 902 is pulled in advance, causing the sliding rod 901, limiting piece 903, and insertion rod 904 to move. Simultaneously, the elastic element 905 is compressed, storing elastic potential energy. After the T-shaped clips 3 are fully inserted into pile 1 and pile 2, the pull block 902 is released, and the elastic element 905 releases its elastic potential energy, pushing the sliding rod 901, limiting piece 903, and insertion rod 904 to move in the opposite direction. The insertion rod 904 quickly inserts into the pre-drilled slots in pile 1 and pile 2, achieving rapid fixation. To ensure the stability of the interlocking pile structure and meet different construction needs, such as adjusting the size between pile body 1 and pile body 2, rotating the rotary cylinder 804 can drive the threaded cylinder 801 and threaded column 803 to move closer or further apart, thereby changing the distance between tension plate 6 and tension plate 7. At this time, tension plate 6 and tension plate 7 will drive the corresponding connected T-shaped clamp 3 to move accordingly. The corresponding T-shaped clamp 3 will drive the corresponding pile body 1 and pile body 2 to move closer or further apart, thereby achieving fine adjustment of the size between pile body 1 and pile body 2 to adapt to different geological conditions and engineering requirements.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
