Description

Technical Field

[0001] This utility model relates to the field of infrastructure engineering technology, specifically to a pre-embedded monitoring pole construction foundation structure. Background Technology

[0002] With the accelerated construction of smart cities, the number of surveillance poles deployed in roads, parks, and other scenarios is increasing year by year. The foundation structure of pre-embedded surveillance poles is the core of their stable operation, and its adaptability, stability, and construction efficiency directly affect the overall project quality. Traditional pre-embedded surveillance pole foundations mostly use fixed-spacing anchoring structures, which are difficult to adapt to different geological conditions after installation. Furthermore, the fixed connection between the surveillance pole and the foundation makes later maintenance and replacement difficult, greatly impacting construction efficiency.

[0003] Therefore, it is necessary to provide a pre-embedded monitoring pole construction foundation structure to solve the problems mentioned in the background art above. Utility Model Content

A limiting cylinder is fixed at the top center of the uppermost anchoring unit, and a monitoring rod is inserted inside the limiting cylinder; The positioning rod is vertically fixed to the bottom periphery of the lowest anchoring unit and is used to position the pouring position of the embedded column. A fastening assembly is disposed between the limiting cylinder and the monitoring rod for fixing the monitoring rod to the pre-embedded column.

[0005] Preferably, the anchoring unit includes: an anchor plate, an installation hole in the middle of the anchor plate, a connecting cylinder fixed in the installation hole, and the connecting cylinder being able to be lifted and sleeved on the outer surface of the embedded column.

[0007] Preferably, a plurality of casting holes are evenly distributed on the anchor plate.

[0011] Compared with the prior art, this utility model provides a pre-embedded monitoring pole construction foundation structure, which has the following beneficial effects: In this invention, the adjustable spacing of the anchoring units can adapt to different geological conditions, solving the problem that traditional fixed-spacing anchors tend to tilt in soft soil.

[0013] Please see Figure 1-4 This utility model provides a pre-embedded monitoring pole construction foundation structure, including: An embedded column 1 is provided with several anchoring units 2 with adjustable spacing arranged along the axial direction on the column body of the embedded column 1. Each anchoring unit 2 is provided with a pouring hole 9 for pouring concrete to the upper and lower sides of each anchoring unit 2. The limiting cylinder 3 is fixed at the top center of the uppermost anchoring unit 2, and a monitoring rod 5 is inserted inside the limiting cylinder 3. The positioning rod 6 is vertically fixed to the bottom periphery of the bottom anchoring unit 2 and is used to position the pouring position of the embedded column 1. Fastening component 4 is disposed between the limiting cylinder 3 and the monitoring rod 5, and is used to fix the monitoring rod 5 to the pre-embedded column 1.

[0014] Specifically, before construction, the spacing of the anchoring units 2 is adjusted according to the soil bearing capacity (determined through geological survey): when the soil is relatively loose, the spacing is reduced to enhance the anchoring force; when the soil is relatively hard, the spacing is increased to reduce material waste. Then, a foundation pit with a depth of 1.2-1.8m is excavated (its shape is adapted to the outer contour of the overall pre-embedded structure formed by each anchoring unit 2). The assembled pre-embedded column 1 is vertically placed into the foundation pit, and the position of the pre-embedded column 1 is initially fixed by inserting the tip of the positioning rod 6 into the soil at the bottom of the foundation pit (ensuring the verticality deviation of the pre-embedded column 1 is ≤1‰). Concrete is poured into the foundation pit, and the concrete is filled through the pouring holes 9 of each anchoring unit 2 to the upper and lower sides of the anchor plate 7 to avoid voids between the anchor plate 7 and the concrete. After the concrete has solidified, the bottom of the monitoring rod 5 is inserted into the limiting cylinder 3, and the monitoring rod 5 is fixed to the pre-embedded column 1 by the fastening assembly 4, completing the installation.

[0015] Among them, the adjustable spacing of the anchoring unit 2 adapts to different geological conditions, solving the problem that traditional fixed spacing anchors are prone to tilting in soft soil; at the same time, the pouring hole 9 ensures that the concrete is densely filled, improving the bonding force between the anchoring unit 2 and the soil; in addition, the positioning rod 6 enables the pre-embedded column 1 to be quickly positioned, reducing the difficulty of verticality calibration during construction and improving construction efficiency.

[0016] Furthermore, the anchoring unit 2 includes: an anchor plate 7, the anchor plate 7 having an installation hole in the middle, a connecting cylinder 8 fixed in the installation hole, and the connecting cylinder 8 being able to be lifted and sleeved on the outer surface of the embedded column 1.

[0017] Furthermore, the embedded column 1 has an external thread structure on its outer side, and the connecting cylinder 8 has an internal thread, and the connecting cylinder 8 is threadedly connected to the embedded column 1.

[0018] It should be explained that the connecting sleeve 8 is welded to the anchor plate 7. The connecting sleeve 8 of the anchoring unit 2 is fitted onto the outer surface of the embedded column 1. The position of the connecting sleeve 8 on the embedded column 1 is adjusted by rotating the anchor plate 7 to adapt to different geological conditions. Each end of the connecting sleeve 8 is provided with a set screw hole (not shown in the figure). After assembly, the set screws are used to tighten the embedded column 1 to prevent the threads from loosening.

[0019] Furthermore, several pouring holes 9 are evenly distributed on the anchor plate 7. This facilitates the use of a vibrator to gently compact the concrete around the foundation pit during the pouring process, ensuring that the concrete fully fills the gaps between the upper and lower parts of the anchor plate 7 through the pouring holes 9, without air bubbles or voids.

[0020] Furthermore, the anchor plate 7 is a circular plate, and the size of the anchor plate 7 of each anchoring unit 2 decreases sequentially from top to bottom.

[0021] Specifically, this structural design allows for a larger contact area with the concrete above the foundation pit, directly absorbing and distributing the main load transmitted by the monitoring rod 5 through the limiting cylinder 3; the lower anchor plate 7 is smaller in size, adapting to the space below the foundation pit, and its top-wide and bottom-narrow shape gradually transmits the load downwards, enhancing the foundation's resistance to tipping.

[0022] Furthermore, the fastening assembly 4 includes: a first connecting plate 10 and a second connecting plate 11. The first connecting plate 10 is coaxially fixed to the upper end of the limiting cylinder 3, and the second connecting plate 11 is fixed to the rod body of the monitoring rod 5. The first connecting plate 10 and the second connecting plate 11 are provided with a plurality of connecting holes evenly and correspondingly through them along the circumference, and each of the connecting holes is fixedly connected by bolts.

[0023] Specifically, during installation, the bottom of the monitoring pole 5 is inserted into the limiting cylinder 3 to ensure complete alignment of the connecting holes of the first connecting plate 10 and the second connecting plate 11. Bolts are then inserted into the aligned connecting holes, washers are fitted, and nuts are tightened. The connection via the connecting plates and bolts facilitates later disassembly and assembly, making maintenance and replacement of the monitoring pole 5 convenient.

[0024] Furthermore, the embedded column 1 is a tubular structure, and the inner diameter of the embedded column 1 is the same as the inner diameter of the limiting cylinder 3 and they are connected; the monitoring rod 5 can be inserted into the embedded column 1 to improve the anti-tipping ability of the monitoring rod 5.

[0025] In practice, the spacing of the anchoring units is adjusted according to the soil bearing capacity (determined through geological survey): when the soil is relatively soft, the spacing is reduced to enhance the anchoring force; when the soil is relatively hard, the spacing is increased to reduce material waste. Then, a foundation pit with a depth of 1.2-1.8m is excavated (its shape is adapted to the overall outline of the structure formed by each anchoring unit 2). The assembled pre-embedded column 1 is vertically placed into the foundation pit, and the position of the pre-embedded column 1 is initially fixed by inserting the tip of the positioning rod 6 into the soil at the bottom of the foundation pit (ensuring the verticality deviation of the pre-embedded column 1 is ≤1‰). Concrete is poured into the foundation pit, and the concrete is filled through the pouring holes 9 of each anchoring unit 2 to the upper and lower sides of the anchor plate 7 to avoid voids between the anchor plate 7 and the concrete. After the concrete has solidified, the bottom of the monitoring rod 5 is inserted into the limiting cylinder 3, and the monitoring rod 5 is fixed to the pre-embedded column 1 by the fastening assembly 4, completing the installation.

[0026] 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.
