Description

Technical Field

[0001] This utility model relates to the field of pile-net composite foundation construction technology, and specifically to a composite foundation pile-net structure construction device. Background Technology

[0002] Pile-net composite foundation, or simply pile-net composite foundation, is a novel foundation reinforcement technology that combines pile foundation and grid wall technology. In this technology, bored cast-in-place piles or vibratory driven piles are used, and the piles are connected by grid walls to form a pile-net composite structure system. This system effectively solves problems such as foundation settlement and insufficient bearing capacity. In cases of weak or highly deformable foundations, it improves foundation stability and ensures foundation safety. A search revealed existing technology (publication number: CN202022463524.8) on a CFG pile composite foundation construction device, which describes that "the shaping tube allows the pile to be cast to the required pile top height in one go, eliminating the need for cutting operations, thus improving safety and construction efficiency; the shaping tube can externally restrain the auger drill rod, preventing it from swaying." The movement affects the verticality of the borehole; the installation and disassembly of the shaping component are more convenient and safer; the structure of the shaping tube is: composed of two semi-cylinders, which are joined together to form a complete cylinder. The structure of the base is: composed of two cuboids, each cuboid having a semi-circular through hole, and the two semi-cylinders of the shaping tube are respectively fixed above the semi-circular through holes on the two cuboids. However, in the existing technology, when the shaping tube composed of semi-cylinders is fixed to an uneven foundation soil layer, the shaping tube becomes skewed, resulting in an incorrect construction position of the pile foundation hole. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a construction device for composite foundation pile network structure is provided to solve the problem that when the semi-cylindrical shaping tube is fixed to an uneven foundation soil layer, the shaping tube becomes skewed, resulting in incorrect pile hole construction position.

[0004] To achieve the above objectives, a construction device for a composite foundation pile network structure is provided, comprising: a pile location construction pipe fitting, wherein a long auger drill is inserted into the inner side of the pile location construction pipe fitting.

[0005] A positioning nail is inserted and fixed to the outer end of the pile location construction pipe. A fixing frame is welded to the upper surface of the positioning nail. An adjusting stud is connected to the inner side of the fixing frame through a bearing. An adjusting head is connected to the upper end of the adjusting stud. A horizontal support plate is connected to the surface of the adjusting stud through a driving block. The horizontal support plate is symmetrically attached to the lower end face of the pile location construction pipe. A limit stud is welded to the upper surface of the horizontal support plate. A pile location positioning plate is sleeved on the inner groove surface of the positioning nail. A center rod is welded to the lower surface of the pile location positioning plate.

[0006] Furthermore, a fixing hole is provided on the lower ring surface of the pile location construction pipe fitting, and a level is symmetrically installed on the lower end surface of the pile location construction pipe fitting.

[0007] Furthermore, the long spiral drilling equipment is drilled into the foundation soil layer through the drill rod, and positioning nails are fixedly inserted into the upper surface of the foundation soil layer, and pile foundation holes are provided on the inner side of the foundation soil layer.

[0008] Furthermore, a protective ring is welded to the upper surface of the fixed frame; and the adjusting column heads are located inside the protective ring.

[0009] Furthermore, the horizontal support plate is connected to the pile location construction pipe through a limiting stud, and the surface of the horizontal support plate is provided with connecting screw holes.

[0010] Furthermore, a central top plate is fixed to the middle of the upper surface of the pile positioning plate; and the central rod is located at the lower end of the central top plate.

[0011] Furthermore, the inner side of the pile location construction pipe fitting is provided with a groove; and the front and rear ends of the pile location positioning plate are in contact with the groove wall of the pile location construction pipe fitting.

[0012] The beneficial effects of this utility model are as follows: the composite foundation pile network structure construction device of this utility model utilizes positioning nails, a fixed frame, adjusting screws, a driving block, and a horizontal support plate to form a leveling structure for the pile position construction pipe. The positioning nails fix the pile position construction pipe to the surface of the foundation soil layer. Rotating the adjusting screws causes the adjusting screws to move up and down, placing the two sets of horizontal support plates on the same horizontal plane. This allows the horizontal support plates to horizontally support the pile position construction pipe, ensuring the accuracy of the pile drilling position during the construction of the composite foundation pile network structure. It effectively avoids the flatness of the foundation soil layer affecting the pile drilling position and improves the construction quality of the composite foundation pile network structure.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a construction device for a composite foundation pile network structure, including: a pile location construction pipe fitting 1, with a long spiral drilling device 5 inserted inside the pile location construction pipe fitting 1.

[0019] A positioning nail column 2 is inserted and fixed to the outer end of the pile location construction pipe fitting 1. A fixing frame 21 is welded to the upper surface of the positioning nail column 2. An adjusting stud 23 is connected to the inner side of the fixing frame 21 through a bearing. An adjusting column head 22 is connected to the upper end of the adjusting stud 23. A horizontal support plate 4 is connected to the surface of the adjusting stud 23 through a driving block 24. The horizontal support plate 4 is symmetrically attached to the lower end face of the pile location construction pipe fitting 1. A limit stud 41 is welded to the upper surface of the horizontal support plate 4. A pile location positioning plate 6 is sleeved on the inner groove surface of the positioning nail column 2. A center rod 62 is welded to the lower surface of the pile location positioning plate 6.

[0020] When constructing a composite foundation pile network structure, the pile holes must first be drilled. The center rod 62 of the pile positioning plate 6 is nailed to the foundation soil layer 3 at the pile hole location. The left horizontal support plate 4 is first screwed to the pile construction pipe fitting 1. Then, the pile construction pipe fitting 1, which matches the pile diameter, is sleeved on the pile positioning plate 6. The right side of the pile construction pipe fitting 1 is sleeved with the limiting stud 41 of the right horizontal support plate 4. After the positioning nails 2 on the left and right sides of the pile construction pipe fitting 1 are driven into the foundation soil layer 3, the left end of the pile construction pipe fitting 1 is connected to the left water... The flat support plate 4 is fixed, and the right end of the pile position construction pipe 1 is not in contact with the right horizontal support plate 4. Rotate the right section column head 22 so that the drive block 24 converts the rotational motion of the adjusting screw 23 into linear motion, which drives the horizontal support plate 4 to move up until it is in contact with the lower end face of the pile position construction pipe 1. The pile position construction pipe 1 can then be fixed in a horizontal position. Then, the drill rod of the long spiral drilling equipment 5 is inserted into the pile position construction pipe 1 to drill into the foundation soil layer 3. Then, concrete is poured into the drilled pile foundation hole. After the concrete is formed, the mattress layer and pile network are laid.

[0021] In this embodiment, a fixing hole 11 is provided on the lower annular surface of the pile location construction pipe fitting 1, and a level 12 is symmetrically installed on the lower end surface of the pile location construction pipe fitting 1. The long spiral drilling equipment 5 is drilled into the foundation soil layer 3 through the drill rod, and a positioning nail column 2 is fixedly inserted into the upper surface of the foundation soil layer 3. A pile foundation hole 31 is provided on the inner side of the foundation soil layer 3.

[0022] As a preferred implementation, the fixing hole 11 facilitates the use of ground nails to further fix the pile construction pipe 1 to the foundation soil layer 3. The level 12 facilitates the observation of the levelness of the pile construction pipe 1. The long spiral drilling equipment 5 drills the pile foundation hole 31 in the foundation soil layer 3 through the drill rod, and then pours concrete into the pile foundation hole 31 to form the pile foundation.

[0023] In this embodiment, a protective ring 25 is welded to the upper surface of the fixed frame 21; and the adjusting column heads 22 are located inside the protective ring 25. The horizontal support plate 4 is connected to the pile construction pipe 1 through the limiting stud 41, and the surface of the horizontal support plate 4 is provided with connecting screw holes 42.

[0024] As a preferred implementation, the protective ring 25 facilitates the hammering of the positioning nail 2 into the foundation soil layer 3. The limiting stud 41 and the connecting screw hole 42 facilitate the screwing and fixing of the horizontal support plate 4 to the pile position construction pipe 1, making it convenient for the horizontal support plate 4 to stably support the pile position construction pipe 1.

[0025] In this embodiment, a central top plate 61 is fixed to the middle of the upper surface of the pile positioning plate 6; and the central rod 62 is located at the lower end of the central top plate 61. A groove is provided on the inner side of the pile construction pipe fitting 1; and the front and rear ends of the pile positioning plate 6 are in contact with the groove wall of the pile construction pipe fitting 1.

[0026] As a preferred implementation method, the pile positioning plate 6, which is sleeved inside the pile position construction pipe fitting 1, is used to position the construction location of the pile foundation hole. This helps to ensure the accuracy of the pile foundation hole position during the construction of the composite foundation pile network structure and improves the construction quality of the composite foundation pile network structure.

[0027] This utility model's composite foundation pile-net structure construction device effectively solves the problem in the prior art where the semi-cylindrical shaping tube is fixed to an uneven foundation soil layer, causing the shaping tube to become skewed and resulting in incorrect pile hole positions. It facilitates ensuring accurate pile hole positions during composite foundation pile-net structure construction, effectively avoids the impact of the foundation soil layer's flatness on the pile hole position, improves the construction quality of composite foundation pile-net structures, and is applicable to composite foundation pile-net structure construction devices.
