Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-seepage wall technology, and in particular to a deep cement-soil mixing pile anti-seepage wall reinforcement structure. Background Technology
[0002] When reinforcing deep cement-soil mixing pile anti-seepage walls, a type of deep cement-soil mixing pile anti-seepage wall reinforcement structure is often used. This structure is a foundation treatment technology that forcibly mixes cement and other curing agents with deep soft soil to form cement-soil piles, which are then interlocked to form a continuous wall. Its core function is to significantly improve the bearing capacity of the foundation, enhance soil stability, and effectively block groundwater seepage. Through in-situ mixing, the cement-soil is fully integrated with the surrounding soil to form a composite anti-seepage system with both high strength and low permeability. This can significantly reduce foundation settlement and prevent seepage damage such as piping. It is especially suitable for scenarios such as soft foundations, dam seepage prevention, and water conservancy project reinforcement.
[0003] The deep cement-soil mixing pile anti-seepage wall reinforcement structure first requires preparation of the construction site, ensuring that the site is flat and free of obstacles. Then, professional equipment is used to drill to the designed depth, while simultaneously injecting cement slurry to mix with the soil to form cement-soil. Next, continuous mixing is carried out to ensure that the cement-soil is fully uniform, ensuring the continuity and integrity of the wall. Finally, curing is carried out, and after the cement-soil reaches a certain strength, the construction of the anti-seepage wall is completed. The entire process emphasizes precise control of the mixing ratio, depth, and uniformity to ensure the anti-seepage effect and structural stability.
[0004] Existing technologies for deep cement-soil mixing pile anti-seepage wall reinforcement structures often employ traditional methods such as single grouting reinforcement or localized strengthening, which fail to effectively improve the overall mechanical properties of the anti-seepage wall. In complex geological conditions or high water pressure environments, they cannot fully guarantee the stability and durability of the anti-seepage wall. Furthermore, existing reinforcement structures have poor integration with the deep cement-soil mixing pile anti-seepage wall, leading to issues such as loosening and detachment of reinforcement components. This prevents the formation of a synergistic force-bearing system, significantly reducing the reinforcement effect. In addition, some reinforcement devices are complex to install and operate, have low construction efficiency, and lack real-time monitoring and dynamic reinforcement adjustment mechanisms for the internal stress distribution of the anti-seepage wall, making them unsuitable for different engineering scenarios. Therefore, an automatic liquid cosmetic filling machine is proposed to address these problems. Utility Model Content
[0005] This utility model proposes a reinforcement structure for deep cement-soil mixing pile anti-seepage walls, aiming to improve the problem that some existing devices cannot reinforce deep cement-soil mixing pile anti-seepage walls.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A deep cement-soil mixing pile anti-seepage wall reinforcement structure includes a water-stop wall. Multiple mixing columns are fixedly connected to the internal space of the water-stop wall. A splicing mechanism is provided at the top of the water-stop wall. A reinforcement mechanism is provided in the internal space of the splicing mechanism. The splicing mechanism includes a steel bar, a positioning base fixedly connected to one side of the steel bar, tight-fitting blocks fixedly connected to the top left and right sides of the positioning base, a side sealing plate fixedly connected to the left side of the positioning base, side sealing grooves slidably connected to the left and right sides of the side sealing plate, and locking grooves slidably connected to the left and right sides of the tight-fitting blocks. A connecting top seat is fixedly connected to the outside of the positioning base, and a steel bar is fixedly connected to one side of the connecting top seat. A docking assembly is provided in the internal space of the positioning base.
[0008] The above-mentioned solution effectively enhances the integrity and stability of the wall and improves its seepage prevention effect by setting multiple mixing columns inside the water-stop wall. The steel bars in the splicing mechanism, through the cooperation of positioning bases, tight clamps, side sealing plates, and side sealing grooves, achieve a tight splicing between adjacent walls, ensuring the seal at the joint and preventing water leakage. The docking components further optimize the splicing process, improving construction efficiency and quality. Furthermore, the reinforcement mechanism, located inside the splicing mechanism, provides additional support to the wall, enhancing the load-bearing capacity and durability of the seepage-stop wall. The overall structural design is reasonable, not only improving seepage prevention performance but also simplifying the construction process and reducing maintenance costs, resulting in significant economic and social benefits.
[0009] As a further description of the above technical solution:
[0010] The reinforcement mechanism includes an expansion tube, an internal threaded connection to a countersunk bolt, an external threaded connection to a hexagonal nut, a fixed external connection to a flat washer, and an adjustment component in the bottom space of the countersunk bolt.
[0011] The above-mentioned solution, through the reinforcement mechanism and the cooperation of expansion tubes, countersunk bolts, hexagonal nuts, and flat washers, forms a stable connection structure, effectively enhancing the overall strength of the seepage barrier. The countersunk bolt design reduces damage to the wall surface, while the flat washers ensure tightness of the connection and prevent loosening. The adjustment component can adjust the bolt tightness according to actual needs, further optimizing the reinforcement effect. This not only improves the load-bearing capacity of the seepage barrier but also simplifies construction operations, ensuring the efficiency and reliability of the reinforcement process, and providing a solid support guarantee for deep cement-soil mixing pile seepage barriers.
[0012] As a further description of the above technical solution:
[0013] The docking assembly includes a first insertion post, a positioning plate fixedly connected to the outer space of the first insertion post, a locking screw fixedly connected to the inside of the first insertion post, a connecting rod fixedly connected to the outside of the positioning plate, insertion post holes on both the left and right sides of the inside of the positioning plate, sealing gaskets fixedly connected to both the left and right sides of the outside of the first insertion post, a second insertion post fixedly connected to the inside of the connecting top seat, a connecting hole on one side of the inside of the first insertion post, and the outside of the first insertion post fixedly connected to the inside of the positioning base.
[0014] The above solution achieves rapid and stable connection of the cutoff wall splicing parts through the precise cooperation of the docking components and the first and second insertion posts. The design of the positioning plate and connecting rod ensures accurate positioning during the docking process, reducing construction errors. The locking screws further enhance the connection's firmness and prevent loosening. The addition of the sealing gasket effectively improves the sealing performance of the docking parts, preventing water leakage. The ingenious design of the insertion post holes and connecting holes makes the docking process smoother and improves construction efficiency. This component not only simplifies the splicing process but also ensures the integrity and sealing of the cutoff wall, providing a reliable guarantee for the reinforcement of deep cement-soil mixing pile cutoff walls and significantly improving the project's seepage prevention effect and durability.
[0015] As a further description of the above technical solution:
[0016] The adjusting assembly includes an expansion head, the top of which is fixedly connected to the bottom space region of the countersunk bolt, and an expansion tube head is fixedly connected to the bottom space region of the expansion tube. The outside of the expansion head is rotatably connected to the inside of the expansion tube head.
[0017] The above solution, through the rotating connection design of the expansion head and expansion tube head of the adjustment component, achieves flexible adjustment of the reinforcement force. The expansion head is fixed to the bottom of the countersunk bolt and penetrates into the expansion tube head as the bolt is tightened. The expansion action enhances the tightness of the connection and ensures the reinforcement effect. This design not only simplifies the adjustment process but also improves construction efficiency, while ensuring the stability and reliability of the reinforcement. It effectively prevents the decline in seepage prevention performance caused by loosening, and provides a more precise and efficient reinforcement method for deep cement-soil mixing pile seepage prevention walls.
[0018] As a further description of the above technical solution:
[0019] The first steel bar has multiple grouting ports inside, and the outside of the grouting ports is opened inside the second steel bar. The bottom space of the grouting ports is fixedly connected to the top of the mixing column.
[0020] The above solution, through multiple grouting ports inside steel bar one extending into steel bar two, achieves uniform injection of grout at the joints of the anti-seepage wall, effectively filling the gaps between the walls and enhancing the overall sealing. The fixed connection between the grouting ports and the top of the mixing column ensures that the grout can directly act on the area around the mixing column, improving the mixing effect and anti-seepage performance. This not only simplifies the grouting process but also improves the reinforcement quality of the anti-seepage wall through precise grouting, effectively preventing water leakage and extending the service life of the anti-seepage wall.
[0021] As a further description of the above technical solution:
[0022] The bottom space of the first steel bar is fixedly connected to the top of the waterstop wall, and the bottom space of the second steel bar is fixedly connected to the top of the waterstop wall.
[0023] The above solution involves fixing both steel bars one and two to the top of the waterstop wall at the bottom, forming a stable connection. This enhances the overall integrity of the anti-seepage wall, effectively preventing displacement or deformation of the wall due to external forces, ensuring the integrity and sealing of the anti-seepage structure, and improving the anti-seepage effect and durability of the project.
[0024] As a further description of the above technical solution:
[0025] The outer left and right sides of the side sealing groove are both opened on the inner left and right sides of the connecting top seat, and the outer left and right sides of the locking groove are both opened on the top left and right sides of the connecting top seat.
[0026] The above solution, by having side sealing grooves and locking grooves respectively opened inside and on top of the connecting top seat, achieves tight engagement and fixation of steel bar one and steel bar two, effectively improving the sealing and stability of the splicing part, simplifying the construction process, and ensuring the overall seepage prevention effect and structural stability of the seepage barrier wall.
[0027] As a further description of the above technical solution:
[0028] The locking screw is externally fixedly connected to the inside of the second insertion post, and the sealing gasket is externally fixedly connected to the left and right sides of the second insertion post.
[0029] The above solution ensures a stable connection of the connecting components by fixing the screws inside the second insertion post, while the sealing gaskets are fixed on both sides of the outside of the second insertion post. This effectively improves the sealing performance of the splicing parts, enhances the integrity and seepage prevention effect of the waterproof wall, simplifies the construction process, and improves project efficiency.
[0030] This utility model has the following beneficial effects:
[0031] 1. In this utility model, the waterstop wall serves as the main body for seepage prevention, cutting off the seepage path of groundwater. The internal stirring column effectively enhances the structural strength and seepage prevention performance. Steel bar one and steel bar two provide stable foundation support. The positioning base and the connecting top seat cooperate with the tight locking block and locking groove. The sealing structure formed by the side sealing plate and the side sealing groove, as well as the design of the insertion column one and insertion column two in the docking assembly and the sealing gasket filling the gap, not only ensure the stability of the horizontal extension connection of the waterstop wall, but also effectively prevent water seepage. It achieves the dual effect of strengthening and splicing the seepage prevention wall, significantly improving the overall seepage prevention performance and structural stability of the device, and providing a reliable guarantee for underground seepage prevention projects.
[0032] 2. In this utility model, the expansion tube, countersunk bolt, expansion head, and expansion tube head enable reliable anchoring force at the bottom of the expansion tube, enhancing the stability of the internal connection of the waterstop wall. The hexagonal nut and countersunk bolt work together to lock and secure the structure, effectively preventing loosening and improving overall structural stability. The flat washer increases the contact area, reduces local pressure, and avoids damage to the connected parts. The multiple grouting ports facilitate the injection of cement grout into the mixing column, filling gaps and further strengthening the structural strength and water-stopping performance. The overall device has a reasonable structure and complete functions, significantly improving construction quality and efficiency, and ensuring the reliability and durability of the waterstop project.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0041] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of a deep cement-soil mixing pile anti-seepage wall reinforcement structure, including a water-stop wall 1, which is the main anti-seepage structure and cuts off the groundwater seepage path. Multiple mixing columns 2 are fixedly connected in the internal space of the water-stop wall 1 to improve the overall strength and anti-seepage performance of the water-stop wall 1 and enhance the stability of the structure. A splicing mechanism 3 is provided at the top of the water-stop wall 1 to realize the horizontal extension and connection of the water-stop wall 1, ensuring the continuity and integrity of the entire anti-seepage wall. A reinforcement mechanism 4 is provided in the internal space of the splicing mechanism 3 to enhance the overall strength and stability of the splicing mechanism 3 and improve the anti-seepage wall's resistance to deformation. The splicing mechanism 3 includes a steel bar 31, which provides a basic support structure for the splicing mechanism 3 and connects to the waterstop wall 1. A positioning base 32 is fixedly connected to one side of the inside of the steel bar 31. This base is a basic component of the splicing mechanism 3 and provides positioning and support to ensure accurate installation of each component. Tightly fastening blocks 33 are fixedly connected to the top left and right sides of the positioning base 32. These blocks cooperate with the fastening grooves 36 to achieve a tight connection between the positioning base 32 and the connecting top seat 37, preventing loosening. A side sealing plate 34 is fixedly connected to the inside left side of the positioning base 32. The side sealing grooves 35 work together to form a sealing structure to prevent groundwater from seeping from the splicing point.
[0042] Specifically, a deep cement-soil mixing pile anti-seepage wall reinforcement structure consists of a water-stop wall 1, a splicing mechanism 3, and a reinforcement mechanism 4. The water-stop wall 1 is the main anti-seepage body, cutting off the groundwater seepage path. It has multiple mixing columns 2 inside to enhance strength, anti-seepage performance, and stability. The splicing mechanism 3 is set at the top of the water-stop wall 1 for horizontal extension and connection to ensure the continuity and integrity of the anti-seepage wall. The reinforcement mechanism 4 inside the splicing mechanism 3 improves its strength, stability, and resistance to deformation. In the splicing mechanism 3, steel bar 31 provides basic support and connects to the water-stop wall 1. The positioning base 32 on one side inside is a basic component to ensure accurate installation of the components. The tight-fitting blocks 33 on the left and right sides of the top of the positioning base 32 cooperate with the locking groove 36 to achieve a tight connection and form a sealed structure to prevent groundwater seepage.
[0043] The side sealing plate 34 has side sealing grooves 35 that are slidably connected to the left and right sides of its exterior. The two side sealing plates 34 work together to form a sealing structure to prevent groundwater from seeping through the joint. The tight clamping block 33 has locking grooves 36 that are slidably connected to the left and right sides of its exterior. These grooves work together with the tight clamping block 33 to achieve a locking connection between the positioning base 32 and the connecting top seat 37. The positioning base 32 is fixedly connected to the connecting top seat 37, which works together with the positioning base 32 to achieve splicing and connection of adjacent waterstop walls 1. At the same time, it provides an installation foundation for the reinforcement mechanism 4. The connecting top seat 37 is fixedly connected to one side of its exterior to provide a basic support structure for the splicing mechanism 3, increase the overall strength and stability of the splicing mechanism 3, and prevent the waterstop wall 1 from deforming or displacing during the stress process. The positioning base 32 has a docking component 39 in the internal space area to achieve precise docking of the two steel bar 1 31 and steel bar 2 38 units, ensuring that the two units are accurately positioned and firmly connected during the splicing process.
[0044] Specifically, the side sealing plate 34 and the side sealing groove 35 work together to prevent groundwater seepage. The tight locking block 33 and the locking groove 36 work together to achieve a locking connection between the positioning base 32 and the connecting top seat 37. The positioning base 32 and the connecting top seat 37 work together to splice adjacent waterstop walls 1 and provide an installation foundation for the reinforcement mechanism 4. The connecting top seat 37 fixes the steel strip 38 to increase the overall strength and stability. The docking component 39 in the internal space area of the positioning base 32 is used for precise docking of two steel strip units to ensure accurate splicing position and firm connection.
[0045] The reinforcement mechanism 4 includes an expansion tube 41, which is the main component of the reinforcement mechanism. It cooperates with a countersunk bolt 42 to provide anchoring force through the expansion of the expansion tube, enhancing the stability of the structure. The countersunk bolt 42 is internally threaded into the expansion tube 41. By rotating the countersunk bolt 42, the expansion head 451 moves within the expansion tube head 452, causing the bottom of the expansion tube 41 to expand and generate anchoring force. A hexagonal nut 43 is externally threaded into the countersunk bolt 42, cooperating with the countersunk bolt 42 to tighten and lock the expansion tube 41, preventing bolt... The countersunk bolt 42 is externally fixed with a flat washer 44, which increases the contact area between the countersunk bolt 42 and the connected parts, disperses pressure, protects the surface of the connected parts from scratches, and prevents the nut from loosening. An adjustment component 45 is provided in the space area at the bottom of the countersunk bolt 42 to realize the expansion function of the expansion tube 41. Through the cooperation of the expansion head 451 and the expansion tube head 452, the rotational movement of the countersunk bolt 42 is converted into radial expansion force, thereby squeezing the internal structure of the waterstop wall 1 and enhancing its density and stability.
[0046] Specifically, the reinforcement mechanism 4 is based on the expansion tube 41, which works in conjunction with the countersunk bolt 42. The expansion of the expansion tube generates anchoring force to improve structural stability. The internal thread of the countersunk bolt 42 connects to the expansion tube 41, and its rotation drives the expansion head 451 to move within the expansion tube head 452, causing the bottom of the expansion tube to expand. Its external thread connects to the hexagonal nut 43 for fastening and locking to prevent loosening. The fixed connection flat washer 44 increases the contact area, disperses pressure, protects the connected parts, and prevents the nut from loosening. The adjustment component 45 in the space area at the bottom of the countersunk bolt 42, with the help of the expansion head 451 and the expansion tube head 452, converts the rotational motion into radial expansion force, which squeezes the inside of the waterstop wall 1, enhancing its compactness and stability.
[0047] Reference Figure 3 and Figure 5The docking assembly 39 includes two inserts, 391 and 397, which work together to dock and position the positioning base 32 and the connecting top seat 37, ensuring splicing accuracy.

The positioning plate 392 has openings on both its left and right sides. Insertion hole 395 provides an installation position for insertion or bolt, enhancing the connection strength of the structure. Sealing gaskets 396 are fixedly connected to the left and right sides of the outside of insertion post 391 to fill the gap between insertion post 391 and insertion post 397 and prevent groundwater seepage. Insert post 397 is fixedly connected inside the connecting top seat 37.

A connecting hole 398 is opened on one side of the inside of insertion post 391 to provide insertion space for insertion post 397 and achieve docking of insertion post 391 and insertion post 397. The outside of insertion post 391 is fixedly connected to the inside of positioning base 32.
[0048] Specifically, the docking assembly 39 consists of two inserts, 391 and 397, which are used to dock and position the positioning base 32 and the connecting top seat 37 to ensure splicing accuracy. The space area of insert 391 is fixed with a positioning plate 392, which can fix itself and provide a connection base for connecting rod 394. It also has a locking screw 393 inside to firmly connect insert 391 and insert 397 to prevent loosening.

A connecting hole 398 is opened on one side inside insert 391 to provide insertion space for insert 397. Insert 391 is fixed inside the positioning base 32.
[0049] The adjusting component 45 includes an expansion head 451, which moves inside the expansion tube head 452 under the drive of the countersunk bolt 42, causing the expansion tube head 452 to expand outward, thereby causing the bottom of the expansion tube 41 to expand and generate anchoring force. The top of the expansion head 451 is fixedly connected to the space area at the bottom of the countersunk bolt 42. The space area at the bottom of the expansion tube 41 is fixedly connected to the expansion tube head 452, which expands outward under the action of the expansion head 451, so that the bottom of the expansion tube 41 is tightly connected to the surrounding soil or structure, providing anchoring force. The outside of the expansion head 451 is rotatably connected to the inside of the expansion tube head 452. The inside of the steel bar 31 is provided with multiple grouting ports 5 for injecting cement grout or other filling materials into the mixing column 2 to enhance the strength and seepage prevention performance of the mixing column 2, and at the same time fill the gap between the mixing column 2 and the surrounding soil. The outside of the grouting ports 5 is opened inside the steel bar 38. The space area at the bottom of the grouting ports 5 is fixedly connected to the top of the mixing column 2.
[0050] Specifically, in the adjusting component 45, the top of the expansion head 451 is fixed to the space area at the bottom of the countersunk bolt 42. Under the drive of the countersunk bolt 42, it moves inside the expansion tube head 452, causing the expansion tube head 452 to expand outward, so that the bottom of the expansion tube 41 expands to generate anchoring force. The steel bar 31 has multiple grouting ports 5 inside, which are opened inside the steel bar 38. The space area at the bottom is fixed to the top of the mixing column 2, and is used to inject cement slurry and other materials to enhance the strength and seepage prevention performance of the mixing column 2 and fill the voids with the surrounding soil.
[0051] Reference Figure 4 and Figure 5 The bottom space of steel bar 31 is fixedly connected to the top of the waterstop wall 1, the bottom space of steel bar 38 is fixedly connected to the top of the waterstop wall 1, the outer left and right sides of the side sealing groove 35 are opened on the inner left and right sides of the connecting top seat 37, the outer left and right sides of the locking groove 36 are opened on the top left and right sides of the connecting top seat 37, the outer side of the locking screw 393 is fixedly connected to the inside of the insert 397, and the outer side of the sealing gasket 396 is fixedly connected to the outer left and right sides of the insert 397.
[0052] Specifically, the bottom space of steel bar 31 and steel bar 38 are fixed to the top of the waterstop wall 1. The side sealing groove 35 is opened on the left and right sides inside the connecting top seat 37. The locking groove 36 is opened on the left and right sides of the top of the connecting top seat 37. The locking screw 393 is fixed inside the insert 397. The sealing gasket 396 is fixed on the left and right sides outside the insert 397.
[0053] Working principle: The waterstop wall 1 acts as the main body for seepage prevention, cutting off the seepage path of groundwater. The internal stirring column 2 enhances its strength and seepage prevention performance. The splicing mechanism 3 is used for the horizontal extension connection of the waterstop wall 1. Steel bar 1 31 and steel bar 2 38 provide basic support. The tight locking block 33 on the positioning base 32 cooperates with the locking groove 36 of the connecting top seat 37 to achieve the connection between the two. The side sealing plate 34 and the side sealing groove 35 form a sealing structure to prevent water seepage. In the docking assembly 39, the first insertion post 391 and the second insertion post 397 cooperate to achieve the docking and positioning of the positioning base 32 and the connecting top seat 37. The positioning plate 392 fixes the first insertion post 391 and connects the connecting rod 394. The locking screw 393 firmly connects the first insertion post 391 and the second insertion post 397. The sealing gasket 396 fills the gap to prevent water seepage, realizing the reinforcement and splicing of the seepage prevention wall.
[0054] First, the expansion tube 41 is inserted into the waterstop wall 1. Then, the countersunk bolt 42, which is threaded inside the expansion tube 41, is rotated. The expansion head 451 at the bottom of the countersunk bolt 42 moves inside the expansion tube head 452 at the bottom of the expansion tube 41. Since the expansion head 451 is externally connected to the inside of the expansion tube head 452, the movement of the expansion head 451 causes the expansion tube head 452 to expand outward, thereby causing the bottom of the expansion tube 41 to expand and generate anchoring force. Then, the hexagonal nut 43, which is threaded to the outside of the countersunk bolt 42, is tightened and locked to prevent the countersunk bolt 42 from loosening. At the same time, the flat washer 44, which is fixedly connected to the outside of the countersunk bolt 42, increases the contact area between the countersunk bolt 42 and the connected parts. Finally, cement grout is injected into the mixing column 2 through the multiple grouting ports 5 opened inside the steel bar 31 and the steel bar 38.
