Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a road traffic light installation structure. Background Technology

[0002] In urban road traffic facilities, the stability of traffic light foundations directly affects the safe operation and service life of the traffic light system. Traditional traffic light installation structures often employ a combination of pre-embedded steel reinforcement bundles and anchor bolts within the foundation trench. Its core components typically include the foundation trench, mounting base, fasteners, and backfill material. However, early technical solutions had significant limitations in terms of structural reinforcement and durability design.

[0003] In traditional foundations, reinforcing bars are typically wrapped around anchor bolts in a single bundle, forming a planar frame through binding or welding. While this design achieves basic fixation, the low density of the reinforcing bars and the simple spatial structure lead to uneven stress distribution within the foundation. Under long-term dynamic loads such as wind loads and vehicle vibrations, micro-cracks are prone to develop at the top of the foundation, potentially causing concrete spalling or reinforcing bar corrosion. Furthermore, the anchor bolts rely solely on localized bundling for fixation, lacking the synergistic effect of vertical reinforcing members. Under complex geological conditions or extreme weather, this can lead to overall bolt group shifting or foundation settlement, severely impacting the installation accuracy and structural stability of traffic lights.

[0004] With the rapid development of intelligent transportation systems, traffic lights are upgrading from simple indication to multi-device integration. Light poles need to support additional facilities such as cameras, sensors, and 5G base stations, significantly increasing load requirements. Traditional foundations, lacking systematic reinforcement structures and relying solely on single steel reinforcement bundles to enclose anchor bolts without forming a coordinated vertical and horizontal three-dimensional reinforcement system, are no longer adequate to meet the mechanical performance requirements of the new scenarios. Utility Model Content

[0005] The purpose of this utility model is to provide a road signal light installation structure to solve the problem of insufficient strength of traditional foundations.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A road traffic light mounting structure includes: a foundation trench, formed below ground level; a mounting base, a mounting base plate, and multiple fasteners, wherein the mounting base plate is mounted in the foundation trench by the fasteners, the fasteners being evenly distributed circumferentially along the mounting base plate and extending along the depth direction of the foundation trench; the mounting base is mounted on the mounting base plate by the fasteners, and the mounting base is used to mount a hollow column of the traffic light; a first reinforcing component, which is wound around the multiple fasteners; a second reinforcing component, which is erected in the foundation trench and arranged along the depth direction of the foundation trench; each fastener being fixedly connected to the second reinforcing component; and landfill material, which is buried in the foundation trench and covers the mounting base, at least part of the hollow column, the mounting base plate, the fasteners, the first reinforcing component, and the second reinforcing component.

[0008] Based on the aforementioned technical means, the road signal light installation structure of this utility model significantly enhances the strength of the signal light installation foundation through multi-dimensional reinforcement design. First, multiple fasteners are evenly distributed circumferentially along the base plate and extend along the depth of the base groove, forming a ring-shaped three-dimensional support frame. This effectively disperses the lateral forces on the signal light and the column, preventing tilting or displacement of the mounting base and improving the anti-overturning capability of the signal light installation foundation from a circumferential perspective. Second, a first reinforcing component is wound around the fasteners, connecting the dispersed fasteners into a whole through a ring or mesh structure. This enhances the cooperative force-bearing performance between the fasteners, further resisting lateral deformation and improving the overall rigidity of the foundation. Third, a second reinforcing component is erected along the depth of the base groove and fixedly connected to the fasteners, forming a depth-direction reinforcing skeleton. This effectively suppresses longitudinal deformation at the bottom of the base groove caused by long-term loads, preventing foundation settlement or cracking and strengthening the stability of the foundation from a longitudinal perspective. Finally, the landfill material integrates the mounting base, mounting foundation plate, fasteners, first reinforcing component, and second reinforcing component into a unified whole structure. Through the wrapping and pressure dispersion effect of the landfill material, each component works together to bear the external load, greatly improving the foundation's bearing capacity and durability.

[0009] Furthermore, the first reinforcing component includes multiple horizontal ribs and multiple vertical ribs. The multiple horizontal ribs are evenly distributed along the depth direction of the foundation groove, and each horizontal rib is connected to two adjacent fasteners at both ends. The multiple vertical ribs are evenly distributed along the circumference of the mounting base plate, and each vertical rib extends along the depth direction of the foundation groove. Each vertical rib is fixedly connected to each horizontal rib.

[0010] Based on the above technical means, the horizontal reinforcement is evenly distributed along the depth of the foundation trench and connected to adjacent fasteners at both ends to form a lateral constraint frame, which effectively suppresses the coordinated deformation of the fasteners under horizontal load; the vertical reinforcement is evenly distributed along the circumference of the installation foundation plate and extends along the depth. After being fixedly connected with the horizontal reinforcement, it forms a cross-grid structure, which significantly improves the overall shear and pull-out resistance of the foundation, reduces the probability of concrete cracking or steel fatigue fracture, and extends the service life of the foundation.

[0011] Meanwhile, the two ends of the horizontal reinforcement are connected to the adjacent fasteners to form a transverse constraint ring, which can effectively limit the deviation of the fasteners during the pouring process; the vertical reinforcement is evenly distributed along the circumference and fixed with the horizontal reinforcement, further eliminating the risk of overall torsion of the fasteners caused by the impact of concrete pouring or subsequent settlement.

[0012] Furthermore, the second reinforcing component includes multiple supports, each in a grid structure, and each support is fixedly connected to a fastener; the multiple supports are evenly distributed along the depth direction of the foundation groove.

[0013] Based on the aforementioned technical methods, the second reinforcing component adopts a grid-like support structure. Its intersecting grid design can simultaneously resist vertical loads (such as the weight of a traffic light pole) and horizontal loads (such as wind vibration and lateral force from vehicles). The geometric stability of the grid structure allows each support to form an independent load-bearing unit within the foundation trench. Through fixed connections with fasteners, local loads are evenly distributed to the surrounding soil, significantly improving the foundation's shear, tensile, and compressive bearing capacity.

[0014] Meanwhile, multiple supports are evenly distributed along the depth of the foundation trench, forming a multi-level support system. The supports near the trench opening mainly bear the direct load of the signal lights and auxiliary equipment, while the supports near the bottom of the trench balance the overall overturning moment through soil reaction forces. The multi-level, layered structure allows stress to be gradient-transmitted along the depth of the foundation trench, avoiding the problem of stress concentration at the bottom.

[0015] Furthermore, it also includes nuts; the fasteners are anchor bolts, which pass through the mounting base plate and extend along the depth direction of the base groove; the ends of the anchor bolts are threaded, the ends of the anchor bolts pass through the mounting base, and the nuts are screwed to the ends of the anchor bolts to fix the mounting base plate and the mounting base.

[0016] According to the above technical means, the end of the anchor bolt is connected to the mounting base via a nut. Tightening the nut applies a controllable preload to the mounting base plate and the mounting base, ensuring a tight fit between their contact surfaces. The anchor bolt extends along the depth of the foundation trench, is anchored at the bottom by backfill material or a second reinforcing component, and is locked to the mounting base at the top by a nut. The threaded connection between the nut and the anchor bolt is detachable; when the signal light needs maintenance, replacement, or height adjustment, simply loosening the nut releases the mounting base from the mounting base plate.

[0017] Furthermore, the mounting base includes a column mounting plate, on which a hollow column is fixed; the column mounting plate and the mounting base plate overlap.

[0018] Based on the above technical means, the column mounting plate and the mounting base plate are overlapped, which significantly increases the contact area between the two, so that the load of the hollow column is evenly transferred to the mounting base plate through the column mounting plate, avoiding the problem of local stress concentration.

[0019] Furthermore, the mounting base also includes stiffening ribs, which are fixed to the column mounting plate and connected to the hollow column.

[0020] Using the aforementioned technical methods, the stiffening ribs are fixed to the column mounting plate and connected to the hollow column, significantly improving the local bending stiffness of the column mounting plate. Through their connection with the hollow column, the stiffening ribs evenly distribute the upper load to the column mounting plate and the mounting base plate, avoiding localized crushing or bolt hole tearing caused by stress concentration.

[0021] Furthermore, the landfill material includes, from top to bottom, a first concrete foundation, a sand cushion layer, and a second concrete foundation.

[0022] Based on the above technical means, the landfill material is divided into a three-layer graded load-bearing structure consisting of a first concrete foundation, a sand cushion layer, and a second concrete foundation. The second concrete foundation serves as the bottom layer, providing high compressive strength support for the installation base plate; the sand cushion layer serves as the middle layer, mitigating the impact of dynamic loads through the embedding effect of sand particles; and the first concrete foundation serves as the top layer, evenly distributing the signal light load over a wider area to avoid local stress concentration.

[0023] The sand cushion layer is located in the middle layer. Its natural permeability can quickly drain the water accumulated inside the foundation. Combined with the structure where the top surface of the first concrete foundation is flush with the ground, it can effectively prevent surface water and groundwater from intruding into the contact surface between the installation foundation plate and the column installation plate, and delay the process of steel corrosion and concrete carbonation.

[0024] Furthermore, it also includes pipe fittings that extend obliquely along the depth of the foundation trench and penetrate the column mounting plate and the mounting base plate to connect with the hollow column; the pipe fittings are used to carry electrical wires.

[0025] Based on the above technical means, the pipes penetrate the column mounting plate and the mounting base plate to form an independent wire channel, completely enclosing the cable inside the foundation and avoiding the risk of short circuit or leakage caused by mechanical damage or environmental corrosion.

[0026] Furthermore, a first through hole is formed on the column mounting plate, and a second through hole is formed on the mounting base plate. The first through hole and the second through hole are connected, and the pipe passes through the first through hole and the second through hole to connect with the hollow column.

[0027] Based on the aforementioned technical means, the design of connecting the first through hole and the second through hole allows the pipe fitting to be directly positioned through the through hole during installation, thereby improving installation efficiency.

[0028] Furthermore, it also includes a grounding component, which is connected to a fastener.

[0029] According to the above technical means, the grounding component is connected to the anchor bolt (fastener), and its deep underground characteristics form a natural grounding electrode, which effectively conducts the lightning current or equipment leakage current into the ground.

[0030] The beneficial effects achieved by this utility model are:

[0031] This utility model's road signal light installation structure significantly enhances the strength of the signal light installation foundation through multi-dimensional reinforcement design. First, multiple fasteners are evenly distributed circumferentially along the base plate and extend along the depth of the foundation groove, forming a ring-shaped three-dimensional support frame. This effectively disperses the lateral forces on the signal light and the column, preventing tilting or displacement of the mounting base and improving the signal light installation foundation's anti-overturning capability from a circumferential perspective. Second, a first reinforcing component is wound around the fasteners, connecting the dispersed fasteners into a whole through a ring or mesh structure. This enhances the cooperative force-bearing performance between the fasteners, further resisting lateral deformation and improving the overall rigidity of the foundation. Third, a second reinforcing component is erected along the depth of the foundation groove and fixedly connected to the fasteners, forming a depth-direction reinforcing skeleton. This effectively suppresses longitudinal deformation at the bottom of the foundation groove caused by long-term loads, preventing foundation settlement or cracking and strengthening the foundation's stability from a longitudinal perspective. Finally, the landfill material integrates the mounting base, mounting foundation plate, fasteners, first reinforcing component, and second reinforcing component into a unified whole structure. Through the wrapping and pressure dispersion effect of the landfill material, each component works together to bear the external load, greatly improving the foundation's bearing capacity and durability.

[0055] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings.

[0056] like Figure 1 As shown, a road traffic light installation structure includes: a foundation trench 1, which is formed below ground level; a mounting base 2, a mounting base plate 3, and a plurality of fasteners 4, wherein the mounting base plate 3 is installed in the foundation trench 1 by the fasteners 4, the fasteners 4 being evenly distributed around the circumference of the mounting base plate 3 and extending along the depth direction of the foundation trench 1; the mounting base 2 is installed on the mounting base plate 3 by the fasteners 4, and the mounting base 2 is used to install the hollow column 51 of the traffic light 5; a first reinforcing component 6, which is wound around the plurality of fasteners 4; a second reinforcing component 7, which is erected in the foundation trench 1 and is arranged along the depth direction of the foundation trench 1; each fastener 4 being fixedly connected to the second reinforcing component 7; and a backfill material 8, which is buried in the foundation trench 1 and covers the mounting base 2, at least part of the hollow column 51, the mounting base plate 3, the fasteners 4, the first reinforcing component 6, and the second reinforcing component 7.

[0057] The road signal light installation structure in this embodiment significantly enhances the strength of the signal light installation foundation through multi-dimensional reinforcement design. First, multiple fasteners 4 are evenly distributed circumferentially along the mounting base plate 3 and extend along the depth direction of the foundation groove 1, forming a ring-shaped three-dimensional support frame. This effectively disperses the lateral forces on the signal light 5 and the hollow column 51, preventing the mounting base 2 from tilting or shifting, thus improving the overturning resistance of the signal light installation foundation from a circumferential perspective. Second, a first reinforcing component 6 is wound around the fasteners 4, connecting the dispersed fasteners 4 into a whole through a ring or mesh structure. This enhances the cooperative force-bearing performance between the fasteners 4, further resisting lateral deformation and improving the overall rigidity of the foundation. Third, a second reinforcing component 7 is erected along the depth direction of the foundation groove 1 and fixedly connected to the fasteners 4, forming a depth-direction reinforcing skeleton. This effectively suppresses longitudinal deformation at the bottom of the foundation groove 1 caused by long-term loads, preventing foundation settlement or cracking, and strengthening the stability of the foundation from a longitudinal perspective. Finally, the landfill material 8 integrates the mounting base 2, mounting foundation plate 3, fasteners 4, first reinforcing component 6, and second reinforcing component 7 into a unified whole structure. Through the wrapping and pressure dispersion effect of the landfill material 8, each component works together to bear the external load, greatly improving the bearing capacity and durability of the foundation.

[0058] like Figure 2 As shown, the first reinforcing component 6 includes multiple horizontal ribs 61 and multiple vertical ribs 62. The multiple horizontal ribs 61 are evenly distributed along the depth direction of the foundation groove 1, and each horizontal rib 61 is connected to two adjacent fasteners 4 at both ends. The multiple vertical ribs 62 are evenly distributed along the circumference of the mounting base plate 3, and each vertical rib 62 extends along the depth direction of the foundation groove 1. Each vertical rib 62 is fixedly connected to each horizontal rib 61.

[0059] In this embodiment, the horizontal reinforcement 61 is evenly distributed along the depth direction of the foundation groove 1, and the two ends are connected to adjacent fasteners to form a horizontal constraint frame, which effectively suppresses the coordinated deformation of the fasteners 4 under horizontal load; the vertical reinforcement 62 is evenly distributed along the circumference of the mounting base plate 3 and extends along the depth. After being fixedly connected with the horizontal reinforcement 61, it forms a cross-grid structure, which significantly improves the overall shear and pull-out resistance of the foundation, reduces the probability of concrete cracking or steel fatigue fracture, and extends the service life of the foundation.

[0060] Meanwhile, the two ends of the horizontal reinforcement 61 are connected to the adjacent fasteners 4 to form a transverse constraint ring, which can effectively limit the deviation of the fasteners 4 during the pouring process; the vertical reinforcement 62 is evenly distributed along the circumference and fixed to the horizontal reinforcement 61, which further eliminates the risk of overall torsion of the fasteners 4 caused by the impact of concrete pouring or subsequent settlement.

[0061] like Figure 1 As shown, the second reinforcing component 7 includes multiple brackets 71, each bracket 71 is in a grid structure, and each bracket 71 is fixedly connected to each fastener 4; the multiple brackets 71 are evenly distributed along the depth direction of the foundation groove 1.

[0062] The second reinforcing component 7 employs a grid-structured support 71. Its intersecting grid design can simultaneously resist vertical loads (such as the weight of a traffic light pole) and horizontal loads (such as wind vibration and lateral force from vehicles). The geometric stability of the grid structure allows each support 71 to form an independent load-bearing unit within the foundation trench 1. Through its fixed connection with fasteners 4, the local load is evenly distributed to the surrounding soil, significantly improving the foundation's shear, tensile, and compressive bearing capacity.

[0063] Meanwhile, multiple supports 71 are evenly distributed along the depth direction of the foundation trench 1, forming a multi-level support system. The supports 71 near the trench opening mainly bear the direct load of the signal lights 5 and auxiliary equipment, while the supports 71 near the bottom of the trench balance the overall overturning moment through soil reaction. The multi-level layered structure allows stress to be gradient-transmitted along the depth direction of the foundation trench 1, avoiding the problem of stress concentration at the bottom.

[0064] like Figure 1 and Figure 5 As shown, it also includes a nut 9; the fastener 4 is an anchor bolt, which passes through the mounting base plate 3 and extends along the depth direction of the base groove 1; the end of the anchor bolt is threaded, the end of the anchor bolt passes through the mounting seat 2, and the nut 9 is screwed to the end of the anchor bolt to fix the mounting base plate 3 and the mounting seat 2.

[0065] The anchor bolt ends are connected to the mounting base 2 via nuts 9. Tightening the nuts applies a controllable preload to the mounting base plate 3 and the mounting base 2, ensuring a tight fit between their contact surfaces. The anchor bolts extend along the depth of the foundation groove 1, are anchored at the bottom by filler material 8 or the second reinforcing component 7, and are locked to the mounting base 2 at the top by nuts 9. The threaded connection between the nuts 9 and the anchor bolts is detachable. When the signal light 5 needs maintenance, replacement, or height adjustment, simply loosening the nuts 9 releases the mounting base 2 from the mounting base plate 3.

[0066] In this embodiment, the threaded connection between the nut 9 and the end of the anchor bolt adopts a sealing design, such as coating with anti-rust glue or adding a rubber gasket, which can effectively block the intrusion of harmful media such as moisture and chloride ions, delay thread corrosion and preload attenuation.

[0067] like Figure 1 and Figure 4 As shown, the mounting base 2 includes a column mounting plate 21, and a hollow column 51 is fixed on the column mounting plate 21; the column mounting plate 21 and the mounting base plate 3 overlap.

[0068] The column mounting plate 21 overlaps with the mounting base plate 3, which significantly increases the contact area between the two, allowing the load of the hollow column 51 to be evenly transferred to the mounting base plate 3 through the column mounting plate 21, thus avoiding the problem of local stress concentration.

[0069] like Figure 1 , Figure 4 and Figure 6 As shown, the mounting base 2 also includes a stiffening rib 22, which is fixed on the column mounting plate 21 and connected to the hollow column 51.

[0070] The stiffening rib 22 is fixed to the column mounting plate 21 and connected to the hollow column 51, which significantly improves the local bending stiffness of the column mounting plate. Through its connection with the hollow column 51, the stiffening rib 22 evenly distributes the upper load to the column mounting plate 21 and the mounting base plate 3, avoiding local crushing or bolt hole tearing caused by stress concentration.

[0071] In this embodiment, as Figure 6 As shown, the stiffening rib 22 has a triangular structure, which can form a spatial truss effect and enhance the lateral stability of the hollow column 51. In extreme weather or vehicle collisions, it can improve the overturning resistance of the signal light 5 and effectively prevent the pole from tipping over.

[0072] The stiffening rib 22 can be prefabricated in the factory (e.g., laser-cut, bent into shape) and fixed on site by welding or bolts. The connection between the stiffening rib 22 and the hollow column 51 can also be by bolts or plug-in. When the signal light 5 needs to be repaired or replaced, the column and the mounting plate can be separated simply by loosening the connecting bolts.

[0073] like Figure 1 As shown, the landfill material 8 includes a first concrete foundation 81, a sand cushion layer 82, and a second concrete foundation 83, which are distributed from top to bottom.

[0074] The landfill material is divided into a three-layer graded load-bearing structure consisting of a first concrete foundation 81, a sand cushion layer 82, and a second concrete foundation 83. The second concrete foundation 83 serves as the bottom layer, providing high compressive strength support for the installation foundation plate 3; the sand cushion layer 82 serves as the middle layer, mitigating the impact of dynamic loads through the embedding effect of sand particles; and the first concrete foundation 81 serves as the top layer, evenly distributing the signal light load over a wider area to avoid local stress concentration.

[0075] The sand cushion layer 82 is located in the middle layer. Its natural permeability can quickly drain the water accumulated inside the foundation. Combined with the structure that the top surface of the first concrete foundation 81 is flush with the ground, it can effectively prevent surface water and groundwater from intruding into the contact surface between the installation foundation plate 3 and the column installation plate 21, thus delaying the process of steel corrosion and concrete carbonation.

[0076] In summary, as Figure 1 As shown, the specific on-site pouring construction process in this embodiment is as follows:

[0077] Excavate foundation trench 1 according to the design dimensions. The depth and width of the trench bottom shall meet the requirements of the signal light load and the volume of the fill material 8. Replace or compact the soft soil layer at the bottom of the trench.

[0078] Use a total station to locate the center point of the anchor bolts and the outline of the mounting base plate 3. Arrange the anchor bolts circumferentially in the foundation groove 1 according to the design spacing, leaving a certain length at the top extending beyond the top surface of the mounting base plate 3. Use a positioning template or adjustable clamps to fix the anchor bolt group, and fit the mounting base plate 3 into the anchor bolt group. The anchor bolts and the mounting base plate 3 are fixed by welding or mechanical connection.

[0079] Templates are installed on the side walls of foundation trench 1, with the top elevation flush with the bottom surface of the installation foundation slab 3. Sealing strips are applied to the template joints to prevent grout leakage. The second concrete foundation 83 is poured, using an immersion vibrator to ensure compaction and avoid collisions with the anchor bolts that could cause displacement. The pour is made until it is flush with the installation foundation slab 3. Before the top surface initially sets, it is manually smoothed, and the contact surface with the installation foundation slab is roughened to enhance adhesion.

[0080] Insert the column mounting plate 21 onto the anchor bolt group and initially secure it with nuts 9. Weld or bolt the hollow column 51 to the column mounting plate 21. Install stiffening ribs 22, welding or bolting adjacent sides of the stiffening ribs 22 to the column mounting plate 21 and the hollow column 51.

[0081] A medium-coarse sand cushion layer 82 is laid on the top surface of the second concrete foundation 83. The sand cushion layer 82 buries the column mounting plate 21 and part of the column mounting plate 21 and hollow column 51. The top surface of the sand cushion layer 82 is leveled to form a flexible buffer layer.

[0082] The first concrete foundation 81 was poured, covering the upper part of the stiffening rib 22, with the top surface flush with the ground.

[0083] like Figure 1 As shown, it also includes a pipe fitting 10, which extends obliquely along the depth direction of the foundation trench 1 and passes through the column mounting plate 21 and the mounting base plate 3 to connect with the hollow column 51; the pipe fitting 10 is used to carry electrical wires.

[0084] The pipe fitting 10 penetrates the column mounting plate 21 and the mounting base plate 3 to form an independent wire channel, completely enclosing the cable inside the base to avoid the risk of short circuit or leakage caused by mechanical damage or environmental corrosion.

[0085] In this embodiment, the pipe fitting 10 is pre-positioned before the second concrete foundation 83 is poured, allowing the electrical wires to be threaded in simultaneously with the foundation construction, thus avoiding delays caused by later excavation and wiring. The pipe fitting 10 is made of corrosion-resistant materials such as galvanized steel pipe or PVC-U, with its bottom embedded inside the second concrete foundation 83 and its top connected to the hollow column 51 with sealant. When the electrical wire needs maintenance or replacement, the wire can be pulled out simply by loosening the sealing cap on the top of the column.

[0086] In this embodiment, the pipe fitting 10 is preferably made of metal (such as galvanized steel pipe), which can form a Faraday cage effect, effectively shielding external electromagnetic interference (such as high-voltage lines and wireless equipment) and ensuring the communication stability of the signal light control system.

[0087] like Figure 4 As shown, a first through hole 211 is formed on the column mounting plate 21, such as Figure 3 As shown, a second through hole 31 is formed on the mounting base plate 3. The first through hole 211 is connected to the second through hole 31. The pipe fitting 10 passes through the first through hole 211 and the second through hole 31 and is connected to the hollow column 51.

[0088] The design of the connection between the first through hole 211 and the second through hole 31 allows the pipe fitting 10 to be directly positioned through the through hole during installation, thereby improving installation efficiency.

[0089] like Figure 1 As shown, it also includes a grounding component 11, which is connected to a fastener 4.

[0090] The grounding component 11 is connected to the anchor bolt (fastener 4), and its deep underground characteristics form a natural grounding electrode, effectively conducting lightning current or equipment leakage current into the ground.

[0091] In this embodiment, the grounding component 11 can be copper stranded wire or galvanized steel stranded wire, which is fixed to the surface of the anchor bolt by welding, crimping, or bolting. Alternatively, copper-clad steel grounding electrodes or galvanized angle steel can be used, which are connected to the anchor bolt by welding or hydraulic crimping and driven into the ground to a certain depth.

[0092] like Figure 1 As shown, in this embodiment, the signal light 5 adopts a layered modular design, consisting of a rain cap 52, a signal display module 53, and a hollow column 51 from top to bottom. The rain cap 52 is located at the top of the structure, featuring an arc-shaped streamlined design and a high-polymer anti-stick coating on its surface, effectively preventing the accumulation of fallen leaves, dust, and other debris. It also has a rainwater diversion function, preventing water accumulation from corroding the upper structure. The signal display module 53 is the core component of the LED signal display, adopting a waterproof rectangular box structure. It integrates a three-color LED light group (red, yellow, and green) and an intelligent control unit. The panel surface is covered with high-transmittance tempered glass, ensuring clear signal visibility in inclement weather. The hollow column 51 serves as the main support structure, using galvanized seamless steel pipes. Signal and power cables are run through it, and its top is connected to the signal display module 53 via a flange, while its bottom extends into the foundation groove 1.
