Description

Technical Field

[0001] This application relates to the field of composite pile foundation technology, and in particular to a composite pile foundation reinforcement structure for deep soft soil. Background Technology

[0002] Composite pile foundation is a foundation engineering technology used to improve soft soil foundations. It is mainly used to support soil layers with low or uneven bearing capacity. It is constructed by combining different types of piles (such as concrete piles, steel pipe piles, etc.) with the foundation soil layer to form a pile foundation system with composite function, thereby improving the bearing capacity and stability of the foundation.

[0003] Existing composite piles consist of a combination of an outer core solidified soil pile and an inner core precast pile. The larger contact area of ​​the outer core solidified soil pile provides lateral friction resistance, while the higher strength precast core pile bears the vertical load, improving the soil condition between the piles. Furthermore, the combination of the outer core solidified soil pile and the inner core precast pile enhances the pile's overall quality. During installation, both the outer core solidified soil pile and the inner core precast pile must be combined.

[0004] However, in actual use, it is difficult to increase the foundation's resistance to subsidence, and because the bond strength between the concrete and the outer core solidified soil pile is relatively small, the reinforcement effect on the foundation is poor, so it needs to be improved. Utility Model Content

[0005] To improve the subsidence resistance of composite pile foundations, this application provides a deep soft soil composite pile foundation reinforcement structure.

[0006] This application provides a composite pile foundation reinforcement structure for deep soft soil using the following technical solution:

[0007] A deep soft soil composite pile foundation reinforcement structure includes a base and a reinforcement mechanism. The reinforcement mechanism is disposed inside the base and includes positive and negative threaded rods. The base has two sets of control plates inside, each control plate having a threaded hole on its right side. The left and right ends of the two sets of positive and negative threaded rods pass through the two sets of threaded holes and extend to the outside of the threaded holes. The left and right ends of the two sets of positive and negative threaded rods are rotatably installed on the inner wall of the base through two sets of bearings. The left and right sides of the base have a set of sliding holes, and the inner wall of each sliding hole is slidably connected to a positioning rod. The ends of the two sets of positioning rods that are close to each other are fixedly installed on the sides of the two sets of positioning rods that are far apart from each other.

[0008] By adopting the above technical solution, and through the cooperation of the positive and negative threaded rods, threaded holes, and control plate, the control plate can push the positioning rod to move, so that the positioning rod extends out of the base and inserts into the soil, thereby improving the device's anti-sinking performance. Furthermore, by setting up the column and the positive and negative threaded rods, the lateral and vertical friction of the concrete in the device can be increased after the concrete is poured, thereby improving the stability of the concrete, preventing the concrete from sliding, and ensuring the reinforcement effect on the foundation.

[0009] Optionally, the base is provided with two hanging rings on its upper surface, and the bottom surface of each hanging ring is fixedly installed to the upper surface of the base.

[0010] By adopting the above technical solution, the device can be easily lifted so that it can be placed inside the foundation.

[0011] Optionally, warning stickers are provided at the front and rear of the base, and the two warning stickers are fixedly installed on the front and back of the base respectively, with their sides close to each other.

[0012] Optionally, the base has two sets of columns inside, and each column has a connecting seat fixedly installed at its bottom end. The inner bottom wall of the base has two sets of threaded grooves, and the two sets of connecting seats are threadedly connected to the two sets of threaded grooves respectively.

[0013] By adopting the above technical solution, the column can increase the lateral friction of the concrete, and the fit between the threaded groove and the connecting seat can facilitate the disassembly of the column to make it easier to install the device.

[0014] Optionally, a control ring is fitted on the outer surface of each of the positive and negative threaded rods, and the two sets of control rings are respectively located in the middle of the two sets of positive and negative threaded rods.

[0015] By adopting the above technical solution, the control ring can easily manipulate the positive and negative threaded rods, so as to control the movement of the control board.

[0016] Optionally, the base is provided with two sets of pins at its bottom, and the upper surface of each pin is fixedly installed to the bottom surface of the base.

[0017] By adopting the above technical solution, the insertion pins can increase the stability of the base and prevent the base from sliding.

[0018] Optionally, the end of each of the pins away from the base is a pointed tip, and the end of each of the positioning pins away from the base is a pointed tip.

[0019] By adopting the above technical solution, the resistance to insertion into the ground is reduced, allowing the positioning rod and pin to be smoothly inserted into the ground.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. By combining the positive and negative threaded rods, threaded holes, and control plate, the control plate can push the positioning rod to move, allowing the positioning rod to extend out of the base and insert into the soil, thereby improving the device's resistance to subsidence. Furthermore, by providing the column and the positive and negative threaded rods, the device can increase the lateral and vertical friction of the concrete after pouring concrete, improving the stability of the concrete, preventing concrete slippage, and ensuring the reinforcement effect on the foundation.

[0022] 2. In use, the device is hoisted using the hanging ring, and then the base is placed inside the excavated pit. Pressure is applied to the base to push the pins into the ground smoothly. Then, by rotating the control ring, the control ring drives the positive and negative threaded rods to rotate. Utilizing the threaded connection between the positive and negative threaded rods and the threaded holes, the control plate moves. As the control plate moves, it pushes the positioning pins out of the sliding holes and inserts them into the soil on both sides of the foundation. Then, the column is installed inside the base through the connecting seat and threaded groove. Subsequently, concrete is poured into the interior of the base. The column increases the lateral friction of the concrete, and the positive and negative threaded rods increase the vertical friction of the concrete. After the concrete hardens, the positive and negative threaded rods can be fixed, effectively preventing them from rotating. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a composite pile foundation reinforcement structure for deep soft soil. (Refer to...) Figure 1 A deep soft soil composite pile foundation reinforcement structure includes a base 1, and a reinforcement mechanism 2 is installed inside the base 1. The reinforcement mechanism 2 includes positive and negative threaded rods 201. Two sets of control plates 202 are provided inside the base 1. Each control plate 202 has a threaded hole 203 on its right side. The left and right ends of the two sets of positive and negative threaded rods 201 pass through the two sets of threaded holes 203 and extend to the outside of the threaded holes 203, respectively. The left and right ends of the two sets of positive and negative threaded rods 201 are rotatably mounted to the inner wall of the base 1 through two sets of bearings. A control ring 3 is fitted on the outer surface of each positive and negative threaded rod 201. The two sets of control rings 3 are located in the middle of the two sets of positive and negative threaded rods 201, allowing for convenient operation of the positive and negative threaded rods 201 to control the movement of the control plates 202.

[0030] Reference Figure 2 The base 1 has a set of sliding holes 205 on both the left and right sides. Each sliding hole 205 has a positioning rod 204 slidably connected to its inner wall. The two sets of positioning rods 204 are fixedly installed at their respective ends, one end close to the other end away from each other.

[0031] By rotating the control ring 3, the control ring 3 drives the positive and negative threaded rod 201 to rotate. By utilizing the threaded connection between the positive and negative threaded rod 201 and the threaded hole 203, the control plate 202 is moved. As the control plate 202 moves, it can push the positioning rod 204 out of the sliding hole 205 and insert it into the soil on both sides of the foundation.

[0032] Reference Figure 1 and Figure 2 Two hanging rings 4 are provided above the base 1. The bottom surface of each hanging ring 4 is fixedly installed to the upper surface of the base 1. The device can be easily lifted by the hanging rings 4 so that it can be placed inside the foundation. Warning stickers 5 are provided at the front and rear of the base 1. The two warning stickers 5 are fixedly installed on the front and back of the base 1 respectively with their sides close to each other. The warning stickers 5 can be used to warn non-workers and prevent them from approaching during construction.

[0033] Reference Figure 3 and Figure 4 The base 1 has two sets of columns 6 inside, and each column 6 has a connecting seat 601 fixedly installed at its bottom. The inner bottom wall of the base 1 has two sets of threaded grooves 602. The two sets of connecting seats 601 are threadedly connected to the two sets of threaded grooves 602 respectively. The columns 6 can increase the lateral friction of the concrete, and the cooperation between the threaded grooves 602 and the connecting seats 601 can facilitate the disassembly of the columns 6 for the installation of the device.

[0034] Reference Figure 4Two sets of pins 101 are provided below the base 1. The upper surface of each pin 101 is fixedly installed to the bottom surface of the base 1. The pins 101 can increase the stability of the base 1 and prevent the base 1 from sliding.

[0035] Reference Figure 4 Each pin 101 has a pointed end away from the base 1, and each positioning rod 204 has a pointed end away from the base 1. This reduces the resistance when inserting into the ground, allowing the positioning rod 204 and pin 101 to be inserted smoothly into the ground.

[0036] The implementation principle of the deep soft soil composite pile foundation reinforcement structure in this application embodiment is as follows: During use, the device is lifted by the hanging ring 4, and then the base 1 is placed inside the excavated foundation pit. Pressure is applied to the base 1 so that the base 1 pushes the insert 101 to be smoothly inserted into the ground. Then, by rotating the control ring 3, the control ring 3 drives the positive and negative threaded rods 201 to rotate. Using the threaded connection between the positive and negative threaded rods 201 and the threaded hole 203, the control plate 202 is moved. As the control plate 202 moves, it can push the positioning insert 204 out of the sliding hole 205 and insert it into the soil on both sides of the foundation. Then, the column 6 is installed inside the base 1 through the connecting seat 601 and the threaded groove 602. Then, concrete is poured into the interior of the base 1. The column 6 can increase the lateral friction of the concrete, and the setting of the positive and negative threaded rods 201 can increase the vertical friction of the concrete. At the same time, after the concrete solidifies, it can fix the positive and negative threaded rods 201, effectively preventing the positive and negative threaded rods 201 from rotating.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
