Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and more specifically, to a drilled pile that is easy to construct as a complete set of equipment. Background Technology

[0002] Drilled piles are a common type of deep foundation engineering structure and an important type of pile foundation. The core principle is to form a pile hole by mechanical drilling, place a steel cage in the hole, and then pour concrete to form a cylindrical pile body, which ultimately transfers the load of the superstructure to a deep, hard soil or rock layer. It is suitable for soft soil foundations, high-rise buildings, bridges, large factories and other scenarios with high requirements for foundation bearing capacity. However, traditional construction methods suffer from problems such as poor equipment coordination, cumbersome process connections, and low construction efficiency. Especially in large-scale projects, there is an urgent need for complete sets of construction methods.

[0003] A search revealed that Chinese patent CN220184001U discloses a bored pile. In this mechanism, inclined steel bars are installed between a first mounting ring and a second mounting ring to resist the pressure generated when the first and second long steel bars deform, and to distribute the pressure to the first and second mounting rings. A fastener is also installed between the second long steel bar and the first mounting ring to resist deformation of the first long steel bar and increase the overall structural strength of the bored pile. The first and second inclined grooves facilitate the installation and fixing of the inclined steel bars; during installation, only the two ends of the inclined steel bar need to be pressed into the first and second inclined grooves respectively. Furthermore, the semi-circular groove facilitates engagement with the first long steel bar, and the C-shaped locking block facilitates engagement with the first mounting ring.

[0004] However, in actual use, the pile body is quite long. During on-site construction, the entire pile body needs to be transported and hoisted. This not only places higher demands on hoisting equipment, but also makes it difficult to align the pile body due to its large size and weight. The position needs to be adjusted repeatedly to complete the installation, which greatly extends the construction period. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a drilled cast-in-place pile that is easy to construct as a complete set, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A bored pile that is easy to construct as a complete set includes an upper column, a middle column at the bottom of the upper column, and a lower column at the bottom of the middle column. The upper column, middle column, and lower column are all hollow cylindrical structures, and a docking mechanism is provided at the bottom of the upper column. The docking mechanism includes a protruding insert ring fixedly disposed on the top of the upper column, a connecting ring fixedly disposed on the bottom of the upper column, a sealing ring fixedly disposed on the bottom of the connecting ring, a threaded ring fixedly disposed inside the sealing ring, a docking ring fixedly disposed on the top of the middle column, a sealing groove and a first threaded groove being formed on the surface of the docking ring, the sealing groove being disposed on one side of the first threaded groove, the sealing ring matching the sealing groove, and the threaded ring being threadedly connected to the first threaded groove.

[0007] By adopting the above technical solution, the upper and middle sections of the column can be quickly assembled without complicated operations, improving construction efficiency. Moreover, after assembly, grout leakage can be effectively prevented, ensuring the sealing performance of the pile. At the same time, the strong compatibility of each component ensures the stable connection of the column, providing a guarantee for construction quality.

[0008] As a further description of the above technical solution: the upper column has a plurality of grouting holes evenly opened in the circumferential direction on the surface of the upper column, and a sealing plug is provided on one side of the grouting hole; the lower column has a guide assembly on its surface, and the guide assembly includes a plurality of positioning rods fixedly disposed on the surface of the lower column, and a matching positioning ring is slidably connected to the surface of the positioning rods. Both sides of the positioning ring are fixedly provided with fixing plates, and the surface of the fixing plates is provided with fixing holes.

[0009] By adopting the above technical solutions, the quality of grouting is guaranteed, the subsequent grouting process is reduced, and the positioning rod and positioning ring in the guide assembly slide and adapt to each other, which can accurately guide the pile body to be lowered, avoid deviation, eliminate the need for repeated adjustments, and the overall structure connects to the complete construction process, thereby improving construction efficiency and accuracy.

[0010] As a further description of the above technical solution: a threaded ring is fixedly provided at the bottom of the middle column, and a fixing ring is fixedly provided at the top of the lower column. A second threaded groove is provided on the inner wall of the fixing ring, and the threaded ring is threadedly connected to the second threaded groove. The middle and lower sections of the column are internally fixed with multiple annular reinforcing ribs, which are made of threaded steel. The upper column is internally fixed with multiple reinforcing columns, which are made of high-performance concrete.

[0011] By adopting the above technical solution, the assembly of two column sections can be completed quickly. The operation is simple and the connection is tight. It is compatible with the complete construction process, improves the assembly efficiency, and enhances the column's resistance to external forces, ensuring structural stability.

[0012] The technical effects and advantages of this utility model are as follows: This utility model adopts a docking mechanism, which significantly improves the convenience and efficiency of complete set construction of bored piles. The column adopts a segmented design. Only by aligning the connecting ring and docking ring, and aligning the threaded ring with the first threaded groove, and then rotating, the connection between the upper and middle sections of the column can be quickly completed. This greatly simplifies the splicing process of the complete set of columns, improves construction efficiency, and reduces the time cost of complete set construction. Moreover, the sealing ring is embedded in the sealing groove and pressed with the thread to prevent grouting leakage, ensuring the stable progress of the grouting process in the complete set construction without the need for additional leak repair operations, ensuring the continuity of the complete set construction. The overall process is smoothly connected, and the components are coordinated and adapted, which greatly reduces the difficulty of complete set construction and improves construction quality and progress. This utility model employs a guiding component, significantly improving the accuracy and convenience of complete drilling and grouting pile construction. During pile lowering, the positioning ring and positioning rod slide to precisely limit pile deviation, eliminating the need for repeated adjustments to the hoisting angle and ensuring the pile is vertically aligned with the pile hole. This greatly reduces alignment difficulty and saves construction time. Furthermore, the guiding component seamlessly integrates with the segmented column assembly process. After the column is sealed and assembled into a whole, it can be directly and smoothly lowered using the guiding structure, eliminating the need for additional guiding facilities and reducing construction steps. Overall, the guiding component ensures the accuracy and stability of pile lowering, simplifies the complete construction process, and improves construction efficiency and quality.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] The embodiments disclosed in this application are as follows: Figure 1-5 The drilled pile shown is easy to construct as a complete set of equipment, including an upper column 1, a middle column 2 at the bottom of the upper column 1, and a lower column 3 at the bottom of the middle column 2. The upper column 1, the middle column 2 and the lower column 3 are all hollow cylindrical structures, and a docking mechanism is provided at the bottom of the upper column 1. The docking mechanism includes a protruding insert ring 4 fixedly installed on the top of the upper column 1, a connecting ring 5 fixedly installed at the bottom of the upper column 1, a sealing ring 6 fixedly installed at the bottom of the connecting ring 5, a threaded ring 7 fixedly installed inside the sealing ring 6, a docking ring 8 fixedly installed on the top of the middle column 2, a sealing groove 9 and a first threaded groove 10 opened on the surface of the docking ring 8, the sealing groove 9 is located on one side of the first threaded groove 10, the sealing ring 6 matches the sealing groove 9, and the threaded ring 7 is threadedly connected to the first threaded groove 10. Keep the assembled middle column 2 and lower column 3 stable as a whole, hoist the upper column 1, and align the connecting ring 5 at the bottom of the upper column 1 with the docking ring 8 at the top of the middle column 2. At this time, the sealing ring 6 at the bottom of the connecting ring 5 needs to be precisely embedded in the sealing groove 9 on the surface of the docking ring 8, while ensuring that the threaded ring 7 inside the connecting ring 5 is aligned with the first threaded groove 10 of the docking ring 8. Slowly lower the upper column 1 and rotate it so that the threaded ring 7 is threadedly connected to the first threaded groove 10 until the sealing ring 6 is completely pressed against the sealing groove 9, thereby achieving the sealed assembly of the upper column 1 and the middle column 2 to form a complete pile body.

[0021] Reference Figure 2-3 As shown, the upper column 1 has a plurality of grouting holes 11 evenly opened in the circumferential direction on the surface of the upper column 1, and a sealing plug is provided on one side of the grouting hole 11. The lower column 3 has a guide assembly on its surface. The guide assembly includes a plurality of positioning rods 12 fixedly set on the surface of the lower column 3. The surface of the positioning rods 12 is slidably connected to a matching positioning ring sleeve 13. Fixing plates 14 are fixedly installed on both sides of the positioning ring sleeve 13, and fixing holes 15 are opened on the surface of the fixing plates 14; Place the fixing plates 14 on both sides of the positioning ring sleeve 13 in the designated position, and use M28 expansion bolts to fix the positioning ring sleeve 13 to the concrete pad layer in conjunction with the fixing holes 15. By connecting the protruding insert ring 4 at the top of the pile body with the hoisting equipment, the complete pile body is slowly lifted and moved above the drilled pile hole. The hoisting angle is adjusted so that the pile body is vertically aligned with the pile hole. The pile body is then slowly lowered. During the lowering process, the positioning ring sleeve 13 is slidably connected to the positioning rod 12 to prevent the pile body from shifting during the descent.

[0022] Reference Figure 4-5 As shown, a threaded ring 16 is fixedly installed at the bottom of the middle column 2, and a fixing ring 17 is fixedly installed at the top of the lower column 3. A second threaded groove 18 is opened on the inner wall of the fixing ring 17, and the threaded ring 16 is threadedly connected to the second threaded groove 18. Multiple annular reinforcing ribs 19 are fixedly installed inside the middle column 2 and the lower column 3. The annular reinforcing ribs 19 are made of threaded steel. Multiple reinforcing columns 20 are fixedly installed inside the upper column 1, and the reinforcing columns 20 are made of high-performance concrete. Check whether the pre-fixed annular reinforcing ribs 19 and threaded steel inside the middle column 2 and the lower column 3 are firmly attached to the inner wall of the column without loosening. Confirm that the high-performance concrete reinforcing column 20 inside the upper column 1 is installed in the correct position without displacement or breakage, so as to lay the foundation for the structural stability after the column is assembled. Next, the lower column 3 is hoisted onto the temporary support platform, ensuring that the fixing ring 17 at its top faces upwards. Then, the middle column 2 is hoisted, aligning the threaded ring 16 at the bottom of the middle column 2 with the second threaded groove 18 on the inner wall of the fixing ring 17. The middle column 2 is then slowly lowered using hoisting equipment while rotating it to ensure that the threaded ring 16 and the second threaded groove 18 are tightly threaded together until the two columns fit together seamlessly, thus completing the assembly of the lower column 3 and the middle column 2.

[0023] Working principle of this utility model: This utility model is a drilled cast-in-place pile that is easy to construct as a complete set. When using this device, the construction site is cleaned, the ground is leveled and the pile position is marked. According to the design depth and diameter of the pile, the parameters of the drilling machinery are adjusted to ensure that the deviation between the drilling position and the design pile position does not exceed the specification requirements. Next, check whether the pre-fixed annular reinforcing ribs 19 and threaded steel inside the middle column 2 and the lower column 3 are firmly attached to the inner wall of the column without loosening. Confirm that the high-performance concrete material of the reinforcing column 20 inside the upper column 1 is installed in the correct position without displacement or breakage, so as to lay the foundation for the structural stability after the column is assembled. And place the fixing plates 14 on both sides of the positioning ring sleeve 13 in the designated position, and use M28 expansion bolts to cooperate with the fixing holes 15 to fix the positioning ring sleeve 13 on the concrete pad. Next, the lower column 3 is hoisted to the temporary support platform, ensuring that the fixing ring 17 at its top faces upward. Then, the middle column 2 is hoisted, so that the threaded ring 16 at the bottom of the middle column 2 is aligned with the second threaded groove 18 on the inner wall of the fixing ring 17. The middle column 2 is slowly lowered using hoisting equipment, while rotating the middle column 2 to make the threaded ring 16 and the second threaded groove 18 tightly threaded together until the two columns fit together without gaps, thus completing the assembly of the lower column 3 and the middle column 2. Next, while keeping the assembled middle column 2 and lower column 3 stable as a whole, hoist the upper column 1 so that the connecting ring 5 at the bottom of the upper column 1 is aligned with the docking ring 8 at the top of the middle column 2. At this time, the sealing ring 6 at the bottom of the connecting ring 5 needs to be precisely embedded in the sealing groove 9 on the surface of the docking ring 8, while ensuring that the threaded ring 7 inside the connecting ring 5 is aligned with the first threaded groove 10 of the docking ring 8. Slowly lower the upper column 1 and rotate it so that the threaded ring 7 is threadedly connected to the first threaded groove 10 until the sealing ring 6 is completely pressed against the sealing groove 9, thereby achieving the sealed assembly of the upper column 1 and the middle column 2 to form a complete pile body. Then, by connecting the protruding insert ring 4 at the top of the pile body with the hoisting equipment, the complete pile body is slowly lifted up and moved above the drilled pile hole. The hoisting angle is adjusted so that the pile body is vertically aligned with the pile hole. The pile body is slowly lowered. During the lowering process, the positioning ring sleeve 13 is slidably connected to the positioning rod 12 to prevent the pile body from shifting during the descent. Then, the grouting pipe of the external grouting equipment is connected to the grouting hole 11 on the surface of the upper column 1. Each grouting hole 11 corresponds to one grouting pipe. Ensure that the grouting pipe and the grouting hole 11 are sealed to avoid grout leakage during the grouting process. According to the design grouting pressure and grouting volume, grouting is carried out in sections from the bottom of the pile to the top. When the grouting pressure reaches the design value and the grouting volume no longer increases, the grouting of that section is stopped, the grouting pipe valve is closed, and the grout is allowed to set. After each section of grouting is completed, the grouting hole 11 is sealed with a special sealing plug to ensure that the sealing plug fits tightly with the grouting hole 11 to prevent the backflow of the grout that has not set. After all sections of grouting are completed, the grouting hole 11 is checked a second time to ensure that there is no grout leakage.

[0024] 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.
