Description

Technical Field

[0001] This utility model relates to the field of support structure technology, and in particular to a rapid support structure combining precast pipe piles and inclined bracing in silty geology. Background Technology

[0002] Precast pipe pile bracing components are important support structures in building engineering, widely used in high-rise buildings, bridges, transportation, and water conservancy projects. This technology utilizes industrialized prefabrication production methods, ensuring stable component quality, high construction efficiency, and eliminating the need for on-site curing, significantly shortening the construction period. The bracing components are precisely positioned using a hydraulic automated integrated machine, reducing construction errors and improving the overall performance of the support structure. Their high load-bearing capacity and space utilization effectively control foundation pit deformation, providing more working space for basement construction, while also conforming to green environmental protection principles and reducing construction pollution.

[0003] Patent publication number CN115419081A discloses a prefabricated embedded foundation pit support structure combining vertical support piles and inclined supports, including a capping beam, support piles, and prefabricated inclined supports. The top of the support piles is fixedly connected to the capping beam, and the top of the prefabricated inclined supports is also fixedly connected to the capping beam. A pipe pile end plate is fixedly connected to the top of the support piles, and end plate reinforcing bars are fixedly connected to the upper surface of the pipe pile end plate, extending into and being fixedly connected to the capping beam. Capping beam reinforcing bars are arranged in the capping beam, and the part of the capping beam that contacts the prefabricated inclined supports is an inclined surface perpendicular to the axis of the prefabricated inclined supports. The prefabricated inclined supports are inserted into the capping beam and fixedly connected by a reinforcing steel structure. An angle steel support plate is fixedly connected at the connection between the capping beam and the prefabricated inclined supports. This invention, while meeting the design requirements for strength and deformation, is more suitable for construction environments with limited space, complex surroundings, and difficult pile extraction compared to existing technologies. Furthermore, it is environmentally friendly, low-cost, and easy to construct.

[0004] However, in the above-mentioned device, the pressure beam 2 and the precast prestressed concrete hollow square pile are only connected by a single welding of precast lattice columns. Its load-bearing capacity is relatively weak and it is difficult to provide effective support for a long time. If a partial fracture occurs, it will be quickly transmitted to the entire fracture surface. Based on this, this utility model is proposed. Utility Model Content

The triangular support rod and the connecting central shaft form a planar triangular support area, and the axial support rod and the connecting rod form an axial triangular support area.

[0013] Furthermore, hooks are fixedly connected to both ends of the connecting shaft, and the hooks are inserted into the insertion block.

[0014] Preferably, a rotating disk is rotatably connected to the fixed pipe pile, and the rotating disk has multiple through holes. When the position of the through hole coincides with the position of the plug rod, the plug rod slides out from the through hole.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Example 1: Refer to Figures 1-7 A rapid support structure combining precast pipe piles and inclined bracing in silty soil includes a capping beam 1, and further includes: steel sheet piles 11 fixedly connected below the capping beam 1, reinforced concrete 12 fixedly connected to the steel sheet piles 11; fixed pipe piles 22 fixedly connected to the capping beam 1, sliding flanges 24 slidably connected to the fixed pipe piles 22, and multiple plug-in rods 222 slidably connected inside the fixed pipe piles 22; cement mixing piles 33, used to be inserted into the cement foundation pit at a fixed angle, inclined support columns 3 fixedly connected to the cement mixing piles 33, fixed flanges 32 fixedly connected to the inclined support columns 3, and pipe pile end plates 2 fixedly connected to the capping beam 1, with fixed flanges 32 on the pipe pile end plates 2. The fixed pipe pile is connected to the end plate steel bar 21, which is inserted into the capping beam 1. The pipe pile end plate 2 is fixedly connected to the fixed pipe pile 22. Multiple sliding grooves 221 are opened in the fixed pipe pile 22. The plug rod 222 is slidably connected in the sliding groove 221. The inclined support column 3 is provided with a plug hole 31, and the position of the plug hole 31 corresponds to the position of the sliding groove 221. The sliding flange 24 and the fixed flange 32 are equipped with fixing bolts 242. The fixed pipe pile 22 is rotatably connected to the rotating disk 23. Multiple through holes are opened on the rotating disk 23. When the position of the through hole coincides with the position of the plug rod 222, the plug rod 222 slides out from the through hole.

[0031] In this utility model, the pipe pile end plate 2 is fixed by inserting the end plate steel bar 21 into the top beam 1. At the same time, the connection between the two can be strengthened by welding. The cement mixing pile 33 is inserted into the cement pit on the ground. The crane adjusts the angle of the cement mixing pile 33 so that the cement mixing pile 33 and the inclined support column 3 are aligned. Due to the need to adjust the angle, there is a certain gap between the fixed pipe pile 22 and the inclined support column 3. After alignment, the insertion rod 222 can slide out from the sliding groove 221 and be inserted into the insertion hole 31, thereby completing the connection and positioning between the fixed pipe pile 22 and the inclined support column 3 and making up for the gap between the two. Preferably, after the insertion rod 222 is inserted into the sliding groove 221, the insertion rod 222 can be welded to the connection between the fixed pipe pile 22 and the inclined support column 3 to increase the connection strength.

[0032] The sliding flange 24 can slide on the fixed pipe pile 22. After the insertion rod 222 is inserted and positioned, the sliding flange 24 can be moved down to connect with the fixed flange 32, so that the sliding flange 24 can wrap and compact the connection between the fixed pipe pile 22 and the inclined support column 3, which can further increase the firmness of the connection between the two.

[0033] The rotating disk 23 can prevent the plug rod 222 from sliding out of the sliding groove 221, thereby avoiding the plug rod 222 from sliding out and affecting the docking process during the docking of the fixed pipe pile 22 and the inclined support column 3. After the docking is completed, the rotating disk 23 is rotated so that the through hole on it is aligned with the position of the plug rod 222. Under the influence of gravity, the plug rod 222 slides out of the sliding groove 221 and is inserted into the plug hole 31.

[0034] Example 2: Refer to Figures 1-7 Similar to Embodiment 1, but further: a plug-in block 241 is fixedly connected to the sliding flange 24, and a connecting rod assembly 4 is connected between adjacent sliding flanges 24. The connecting rod assembly 4 is plugged into the plug-in block 241. The connecting rod assembly 4 includes a connecting central shaft 41, a connecting rod 42, a triangular support rod 43, and an axial support rod 44. The triangular support rod 43 and the connecting central shaft 41 form a planar triangular support area, and the axial support rod 44 and the connecting rod 42 form an axial triangular support area. Hooks 45 are fixedly connected to both ends of the connecting central shaft 41 and are plugged into the plug-in block 241.

[0035] The connecting rod assembly 4 is inserted into the plug block 241 on the sliding flange 24 via the hook 45, and the two are fixedly connected by welding. Through the connection of the connecting rod assembly 4, the inclined support columns 3 in the entire foundation pit form a whole. When one of the inclined support columns 3 breaks, the adjacent inclined support columns 3 can be supported by the inclined support column 3 at the broken point of the connecting rod assembly 4, thereby reducing the loss caused by the loss of support in the damaged part. If it is discovered in time, it can be remedied.

[0036] The triangular support rod 43 and the connecting central axis 41 form a planar triangular support area, which is supported by multiple connecting rods 42, thereby increasing the support force and stability on the plane. The axial support rod 44 and the connecting rod 42 form an axial triangular support area, thereby increasing the support force and stability in the longitudinal direction. This allows the connecting rod assembly 4 to have sufficient rigid support force at multiple angles, making the connection of the inclined support column 3 more stable.

[0037] When using the equipment, the user first fixes the pipe pile end plate 2 to the capping beam 1. Then, the cement mixing pile 33 and the inclined support column 3 are hoisted into the uncured cement pit and the angle is adjusted so that the inclined support column 3 is aligned with the fixed pipe pile 22. Then, the rotating disk 23 is rotated so that the plug rod 222 slides out and is inserted into the plug hole 31. The plug rod 222 is then welded. After welding, the sliding flange 24 is moved down and the sliding flange 24 is connected to the fixed flange 32 with the fixing bolt 242. Finally, the connecting rod assembly 4 is inserted into the plug block 241 and welded.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
