Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, specifically a prefabricated assembled hydrophilic platform pile foundation structure. Background Technology

[0002] In the construction of waterfront platforms, the stability and construction efficiency of the pile foundation structure are crucial factors affecting project quality. Currently, traditional pile foundation construction relies heavily on on-site casting or the assembly of prefabricated components. While these methods meet basic requirements, they have limitations in terms of construction cycle and assembly precision. Furthermore, traditional construction methods are less adaptable to the site environment, and their application in complex geological conditions may face additional technical challenges.

[0003] Therefore, we have made improvements to this by proposing a prefabricated, assembled hydrophilic platform pile foundation structure. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems of long construction cycle, low assembly accuracy and poor adaptability to complex geological conditions of current hydrophilic platform pile foundation structures.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a prefabricated, assembled hydrophilic platform pile foundation structure, comprising a pile foundation body and a connecting and adjusting assembly. The pile foundation body is composed of multiple prefabricated units, each of which is connected and fixed together via the connecting and adjusting assembly. The connecting and adjusting assembly includes a positioning component and a locking component. The positioning component guides and restricts the relative positions of adjacent prefabricated units, while the locking component securely fixes adjacent prefabricated units together. A foundation adaptation assembly is provided at the bottom of the pile foundation body to enhance the stability of the pile foundation structure under different geological conditions.

[0006] The foundation adaptation component includes a support plate and an adjusting rod. The bottom surface of the support plate has several conical protrusions with their tips pointing downwards to improve the interlocking force between the support plate and the foundation. The adjusting rod passes through the support plate and is threadedly connected to it. The bottom end of the adjusting rod has an expansion disc with a diameter larger than that of the adjusting rod to increase the support area. The top end of the adjusting rod has a rotating handle. Rotating the handle moves the adjusting rod up and down along the support plate, thereby adjusting the position of the expansion disc to adapt to different foundation depths.

[0007] As a preferred technical solution of this application, each prefabricated unit of the pile foundation body includes a main beam and a side beam. The main beam has insertion slots at both ends, and one end of the side beam has a connector. The connector matches the insertion slot, and the connection between the main beam and the side beam is achieved by inserting the connector into the insertion slot. The inner wall of the insertion slot has an elastic buckle, and the outer wall of the connector has a groove corresponding to the elastic buckle. When the connector is fully inserted into the insertion slot, the elastic buckle embeds into the groove, thereby achieving initial fixation of the main beam and the side beam.

[0008] As a preferred technical solution of this application, the connection adjustment assembly further includes a limiting plate, which is disposed at the connection between two adjacent prefabricated units. Positioning holes are provided on both sides of the limiting plate, corresponding to through holes on the main beam and side beam. Bolts passing through the positioning holes and through holes are used to achieve a fixed connection between the limiting plate and the prefabricated unit. A reinforcing rib is provided in the middle of the limiting plate, extending along the length of the limiting plate to improve its rigidity.

[0009] As a preferred technical solution of this application, the positioning component includes a guide post and a guide sleeve. The guide post is fixed to the end of one prefabricated unit, and the guide sleeve is fixed to the end of another prefabricated unit. The guide post and the guide sleeve are slidably engaged, thereby guiding the docking process of adjacent prefabricated units. The outer wall of the guide post is provided with scale lines, which are used to indicate the depth of the guide post inserted into the guide sleeve, so as to accurately control the docking position of adjacent prefabricated units.

[0010] As a preferred technical solution of this application, the locking component includes a locking nut and a locking rod. The locking rod passes through the connection between two adjacent prefabricated units and is threadedly connected to the prefabricated unit. The locking nut is tightened at both ends of the locking rod, thereby firmly fixing the two adjacent prefabricated units together. The locking rod has anti-slip grooves in the middle, which are used to increase the friction between the locking rod and the prefabricated unit and prevent the locking rod from loosening.

[0011] As a preferred technical solution of this application, the top of the pile foundation body is provided with an installation platform, and the bottom surface of the installation platform is provided with a plurality of connecting columns. The connecting columns correspond to the mounting holes on the main beam and the side beam. The installation platform is fixedly connected to the pile foundation body by bolts passing through the connecting columns and the mounting holes. The top surface of the installation platform is provided with an anti-slip layer, which is made of wear-resistant material to improve the service life of the installation platform.

[0012] As a preferred technical solution of this application, the foundation adapter component further includes drainage holes that penetrate the support plate and are evenly distributed on the surface of the support plate. These drainage holes are used to drain accumulated water and prevent corrosion of the support plate. A filter screen is provided on the inner wall of each drainage hole to prevent mud and sand from entering and clogging the drainage holes.

[0013] As a preferred technical solution of this application, the bottom surface of the expansion disk is a planar structure, and the diameter of the expansion disk is more than twice the diameter of the adjustment rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In this application, the following solutions address the instability of traditional pile foundation structures under complex geological conditions by incorporating a foundation adaptation component. The conical protrusion on the bottom of the support plate enhances the interlocking force between the support plate and the foundation. The combined use of the adjusting rod and the expansion disc allows for adjustment of the support area according to the foundation depth, thereby strengthening the stability of the pile foundation structure. The connection adjustment component solves the problem of low assembly precision in traditional pile foundation structures. The sliding cooperation of the guide column and guide sleeve guides the docking process of adjacent prefabricated units. The scale lines facilitate precise control of the docking position, and the use of locking components ensures the firm fixation of adjacent prefabricated units. The prefabricated units and installation platform solve the problem of long construction cycles in traditional pile foundation structures. The modular design of the prefabricated units allows most of the processing steps to be completed in the factory, with only simple splicing and fixing required on-site, significantly shortening the construction cycle. In summary, this invention provides a highly efficient, stable, and adaptable hydrophilic platform pile foundation structure, effectively overcoming the shortcomings of existing technologies.

Detailed Implementation

[0017] This utility model provides a prefabricated, assembled hydrophilic platform pile foundation structure, the specific implementation of which is described in detail with reference to the accompanying drawings. Figure 1 As shown, the overall structure includes a pile foundation body 1 and a foundation adapter component 6. The pile foundation body 1 is composed of multiple prefabricated units 2, which are connected and fixed together by a connecting adjustment component 3. The connecting adjustment component 3 includes a positioning element 4 and a locking element 5. The positioning element 4 guides and restricts the relative position of adjacent prefabricated units 2, and the locking element 5 securely fixes adjacent prefabricated units 2 together. The foundation adapter component 6 is located at the bottom of the pile foundation body 1. The foundation adapter component 6 includes a support plate 7, an adjusting rod 8, and an expansion disc 9. The bottom surface of the support plate 7 has several conical protrusions with the tips facing downwards to enhance the interlocking effect with the foundation.

[0018] like Figure 1 As shown, the support plate 7 is a rectangular flat plate structure with evenly distributed conical protrusions on its bottom surface. The tips of the protrusions extend downwards, allowing them to insert into the foundation surface to form a stable mechanical engagement. An adjusting rod 8 passes through the support plate 7 and is threadedly connected to it. An expansion disc 9 is fixed to the bottom end of the adjusting rod 8; the diameter of the expansion disc 9 is larger than the diameter of the adjusting rod 8, used to expand the support area. A rotating handle 10 is provided at the top of the adjusting rod 8. Rotating the handle 10 moves the adjusting rod 8 up and down along the support plate 7, thereby adjusting the position of the expansion disc 9 to adapt to different foundation depths. Drainage holes 23 are also provided on the support plate 7, penetrating the plate and evenly distributed on its surface. A filter screen 24 is provided on the inner wall of each drainage hole 23 to prevent mud and sand from entering and causing blockage.

[0019] The bottom surface of the expansion disk 9 is a flat structure, and the diameter of the expansion disk 9 is more than twice the diameter of the adjusting rod 8.

[0020] like Figure 1 As shown, the prefabricated unit 2 includes a main beam 11 and a side beam 12. The main beam 11 has insertion slots 13 at both ends, and the side beam 12 has a connector 14 at one end. The connector 14 matches the insertion slot 13, and the main beam 11 and side beam 12 are connected by inserting the connector 14 into the insertion slot 13. The inner wall of the insertion slot 13 has an elastic buckle 15, and the outer wall of the connector 14 has a groove corresponding to the elastic buckle 15. When the connector 14 is fully inserted into the insertion slot 13, the elastic buckle 15 is embedded in the groove for initial fixation. A limiting plate 16 is located at the connection point of two adjacent prefabricated units 2. The limiting plate 16 has positioning holes on both sides, corresponding to the through holes on the main beam 11 and side beam 12. The limiting plate 16 is fixedly connected to the prefabricated unit 2 by bolts passing through the positioning holes and through holes. A reinforcing rib is provided in the middle of the limiting plate 16, extending along the length of the limiting plate 16 to improve rigidity.

[0021] The positioning component 4 includes a guide post 17 and a guide sleeve 18. The guide post 17 is fixed to the end of one prefabricated unit 2, and the guide sleeve 18 is fixed to the end of another prefabricated unit 2. The guide post 17 and the guide sleeve 18 are slidably engaged, thereby guiding the docking process of adjacent prefabricated units 2. The outer wall of the guide post 17 is provided with scale lines, which are used to indicate the depth of insertion of the guide post 17 into the guide sleeve 18 for precise control of the docking position. The locking component 5 includes a locking rod 19 and a locking nut. The locking rod 19 passes through the connection between two adjacent prefabricated units 2 and is threadedly connected to the prefabricated unit 2. The locking nut is tightened at both ends of the locking rod 19, thereby firmly fixing the two adjacent prefabricated units 2 together. The locking rod 19 has anti-slip grooves in the middle, which are used to increase the friction between the locking rod 19 and the prefabricated unit 2 to prevent loosening.

[0022] like Figure 2 As shown, the top of the pile foundation body 1 is equipped with an installation platform 20, and the bottom surface of the installation platform 20 is provided with several connecting columns 21. The connecting columns 21 correspond to the mounting holes on the main beam 11 and the side beam 12. The installation platform 20 is fixedly connected to the pile foundation body 1 by bolts passing through the connecting columns 21 and the mounting holes. The top surface of the installation platform 20 is provided with an anti-slip layer 22, which is made of wear-resistant material to improve service life. The surface of the anti-slip layer 22 of the installation platform 20 has a rough texture, which can provide good anti-slip performance in humid environments.

[0023] In actual construction, the dimensions of the main pile foundation 1 and the number of prefabricated units 2 are first determined according to the design requirements. Then, the prefabricated units 2 are manufactured in the factory. The main beam 11 and side beam 12 of the prefabricated unit 2 are initially assembled using interlocking slots 13 and interlocking connectors 14. The fit between the elastic buckle 15 and the groove ensures connection stability. Subsequently, the limiting plate 16 is installed at the connection point of adjacent prefabricated units 2, and the limiting plate 16 is fixed with bolts to further enhance the connection strength. The sliding fit between the guide column 17 and the guide sleeve 18 guides the docking of adjacent prefabricated units 2, and the scale lines help construction personnel accurately control the docking depth. Finally, the fixing is completed using the locking rod 19 and the locking nut.

[0024] The installation process of the foundation adapter component 6 is as follows: First, place the support plate 7 in the predetermined position. Adjust the height of the adjusting rod 8 by rotating the handle 10 to achieve the appropriate depth of the expansion plate 9. The large diameter of the expansion plate 9 can effectively distribute the load. The conical protrusion on the bottom surface of the support plate 7 inserts into the foundation surface to form a stable engagement. The drainage hole 23 is used to drain accumulated water to prevent corrosion, and the filter screen 24 prevents mud and sand from entering the drainage hole 23 to avoid blockage. Finally, connect the pile foundation body 1 to the foundation adapter component 6 to ensure the stability of the overall structure.

[0025] The installation process of the mounting platform 20 is as follows: Align the connecting column 21 with the mounting holes on the main beam 11 and the side beam 12, and connect the mounting platform 20 to the pile foundation body 1 by fixing it with bolts. The anti-slip layer 22 on the top surface of the mounting platform 20 can meet the usage requirements of the waterfront platform, and at the same time has high wear resistance to extend its service life. Most of the processing procedures are completed in the factory, and only simple splicing and fixing are required on site to complete the installation, which greatly shortens the construction cycle.

[0026] This utility model achieves a highly efficient and stable hydrophilic platform pile foundation structure through the above specific embodiments, solving the problems of long construction cycle, low assembly accuracy, and poor adaptability to complex geological conditions of traditional pile foundation structures.

[0027] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0028] In the actual construction process, the dimensions of the main pile foundation 1 and the number of prefabricated units 2 are first determined according to the design requirements, and the prefabricated units 2 are manufactured in the factory. Then, the main beam 11 and side beam 12 are initially assembled with the connector 14 via the insertion slot 13. Specifically, after the connector 14 is inserted into the insertion slot 13, the elastic buckle 15 expands outward under force. When the connector 14 is fully inserted, the elastic buckle 15 embeds into the groove on the outer wall of the connector 14, forming a preliminary fixation. The core of this step lies in the fit between the elastic buckle 15 and the groove, which ensures the connection stability of the main beam 11 and the side beam 12 through mechanical interlocking, avoiding the loosening problems that may occur with traditional bolt connections.

[0029] Next, the limiting plate 16 is installed at the connection between two adjacent prefabricated units 2. The positioning holes on both sides of the limiting plate 16 correspond to the through holes on the main beam 11 and the side beam 12, and bolts are used to further fix it through the positioning holes and through holes. The reinforcing rib in the middle of the limiting plate 16 extends along the length direction, enhancing the overall rigidity of the limiting plate 16 and thus improving the connection strength between adjacent prefabricated units 2. This design effectively reduces the risk of structural instability caused by the accumulation of assembly errors.

[0030] During the docking of adjacent precast units 2, the sliding fit between the guide post 17 and the guide sleeve 18 plays a crucial role. As the construction workers push the adjacent precast units 2 closer, the guide post 17 gradually inserts into the guide sleeve 18, with scale lines indicating the insertion depth to ensure precise control of the docking position. After docking, the locking rod 19 passes through the connection point of the adjacent precast units 2 and is threaded onto the precast units 2. The locking nuts are tightened at both ends of the locking rod 19, thereby firmly fixing the adjacent precast units 2 together. The anti-slip texture in the middle of the locking rod 19 increases friction and prevents the locking components from loosening during long-term use.

[0031] The installation process of the foundation adaptation component 6 is as follows: First, the support plate 7 is placed in the predetermined position, and the conical protrusion on the bottom surface of the support plate 7 is inserted into the foundation surface to form a stable mechanical engagement. Then, by rotating the handle 10, the adjusting rod 8 is moved up and down along the support plate 7 to adjust the position of the expansion disc 9 to adapt to foundation conditions of different depths. The expansion disc 9 has a large diameter, which can effectively distribute the load and enhance the bearing capacity of the pile foundation structure. The drainage holes 23 on the support plate 7 penetrate its surface, and the evenly distributed design helps to quickly drain accumulated water, while the filter screen 24 prevents mud and sand from entering the drainage holes 23, avoiding blockage. This design significantly improves the adaptability and durability of the pile foundation structure under complex geological conditions.

[0032] The installation process of the mounting platform 20 is as follows: Align the connecting column 21 with the mounting holes on the main beam 11 and the side beam 12, and fix it with bolts to connect the mounting platform 20 to the pile foundation body 1. The anti-slip layer 22 on the top surface of the mounting platform 20 is made of wear-resistant material, and its rough texture can provide good anti-slip performance in wet environments, meeting the actual use requirements of the hydrophilic platform. At the same time, the wear-resistant properties of the anti-slip layer 22 extend the service life of the mounting platform 20.

[0033] The entire construction process involves most of the manufacturing steps in the factory, with only simple splicing and fixing required on-site for installation. This modular design significantly shortens the construction cycle and lowers the technical threshold for manual operation, thereby reducing construction costs. Furthermore, due to the standardized production of prefabricated unit 2, assembly accuracy is significantly improved, avoiding the error accumulation problems that may occur in traditional construction methods.

[0034] Through the above steps, this utility model achieves a highly efficient and stable hydrophilic platform pile foundation structure. The mechanical engagement of the conical protrusion of the support plate 7 with the foundation, the load distribution function of the expansion disc 9, and the drainage design of the drainage hole 23 jointly solve the technical problem of pile foundation structure stability under complex geological conditions. The sliding fit between the guide column 17 and the guide sleeve 18, and the anti-loosening design of the locking rod 19 ensure high-precision connection between the prefabricated units 2. The anti-slip layer 22 design of the installation platform 20 further enhances the safety and practicality of the hydrophilic platform. Combining the above technical means, this utility model effectively overcomes the shortcomings of the prior art and provides reliable technical support for the construction of hydrophilic platforms.
