Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal engineering technology, and in particular to a traffic pole foundation and traffic pole that facilitates crossing. Background Technology
[0002] In urban areas of all levels, various municipal pipelines are typically constructed concurrently or reserved for future civil engineering access. While main stormwater and sewage pipelines are generally located in the motor vehicle lanes, power, communication, lighting, water supply, heating, and gas pipelines are preferentially located on sidewalks or median strips. Depending on traffic demands, the entrance and exit lanes at intersections are often widened, usually by reducing the width of green belts or sidewalks. Additionally, various directional signs, road signs, traffic lights, and monitoring facilities are installed at intersections.
[0003] Traffic poles are typically erected on medians or sidewalks, and their foundations are usually solid concrete foundations. For larger signs or traffic lights, surveillance cameras, and other poles with long cantilever arms, these foundations often encroach on the space available for the installation of pipelines.
[0004] In actual engineering projects, conflicts often arise at intersections due to space constraints, leading to conflicts between traffic pole foundations and municipal pipeline layouts. Either the traffic foundations are forced to be narrower, affecting the stability of the traffic poles, or pipelines are crammed into confined spaces without adhering to minimum spacing requirements, or some pipelines are routed under the carriageway, requiring road excavation or enclosure measures that affect pavement construction and hinder future maintenance. Utility Model Content
[0005] The main purpose of this utility model is to propose a convenient traffic pole foundation for crossing lines, aiming to avoid the pole foundation encroaching on the space for pipeline layout.
[0006] To achieve the above objectives, the present invention proposes a traffic pole foundation for convenient crossing, comprising:
[0007] The base includes a chassis and a column mounting position. The chassis is used for installation on the ground of a sidewalk or median strip, and the column mounting position is located at the upper end of the chassis for installing the column of a traffic pole.
[0008] A hollow cable-passing structure is disposed at the lower end of the chassis. The hollow cable-passing structure has a cable-passing channel that penetrates the middle of the hollow cable-passing structure.
[0009] Multiple anchor bolts and nuts are distributed on the outer edges of the base and the hollow cable passage structure. Each anchor bolt includes a screw section, an anchoring section, and a hook section connected in sequence. The anchoring section and the hook section are anchored to the hollow cable passage structure. The screw section passes through the chassis from above and is fixed to the chassis and the hollow cable passage structure by screwing it with the nut.
[0010] Optionally, the lower part of the hollow wire-passing structure protrudes outward in the horizontal direction.
[0011] Optionally, both the anchoring section and the hook section are located inside the sidewall of the hollow cable-passing structure and are spaced apart from the cable-passing channel.
[0012] Optionally, the length direction of the hollow cross-pass structure is the extension direction of the sidewalk or median strip on which it is installed, the cross-pass channel runs through the hollow cross-pass structure along its length direction, and multiple anchor bolts and nuts are provided on both sides of the hollow cross-pass structure along the length direction of the road.
[0013] Optionally, the traffic pole foundation for easy passage also includes a base flange, which is placed between the chassis and the hollow passage structure.
[0014] A traffic pole includes a post, a beam, functional components, and a traffic pole base as described above for facilitating crossing. The post is installed at the post mounting position, the beam is installed on the upper part of the post, and the functional components are installed on the beam.

[0031] This utility model proposes a traffic pole foundation that facilitates crossing.
[0032] In the embodiments of this utility model, such as Figures 1 to 4As shown, the foundation for the convenient crossing traffic pole includes a base, a hollow crossing structure 20, and multiple anchor bolts 31 and nuts 32. The base includes a chassis 10 and a column 41 mounting position. The chassis 10 is used for installation on the ground of the sidewalk or median strip. The column 41 mounting position is located at the upper end of the chassis 10 and is used to install the column 41 of the traffic pole. The hollow crossing structure 20 is located at the lower end of the chassis 10 and has a crossing channel that runs through the middle of the hollow crossing structure 20. Multiple anchor bolts 31 and nuts 32 are distributed on the outer edges of the base and the hollow crossing structure 20. Each anchor bolt 31 includes a screw section, an anchoring section, and a hook section connected in sequence. The anchoring section and the hook section are anchored to the hollow crossing structure 20. The screw section passes through the chassis 10 from above and is fixed to the chassis 10 and the hollow crossing structure 20 by screwing it with the nut 32.
[0033] Specifically, the hollow cable passage structure 20 and the anchor bolts can be prefabricated and installed together before being transported to the construction site and installed on the ground. After installation, the hollow cable passage structure 20 is buried underground, and the internal cable passage allows municipal pipelines 21 (electricity, communication, lighting, water supply, heating, gas, etc.) to pass through directly. The chassis 10 is fixed to the hollow cable passage structure 20 by multiple anchor bolts 31 and nuts 32, providing stable support for the installation of the base. The mounting position of the column 41 is set in the chassis 10, which facilitates the installation of the traffic pole column 41.
[0034] This utility model's technical solution involves setting a base, a hollow cable-passing structure 20, and multiple anchor bolts 31 and nuts 32. The base includes a chassis 10 and a column 41 mounting position. The column 41 mounting position is used to install the column 41 of the traffic pole. The hollow cable-passing structure 20 is located at the lower end of the chassis 10. In this way, the base and the hollow cable-passing structure 20 can be fixed together by multiple anchor bolts 31 and nuts 32. At the same time, the anchor bolts 31 adopt a three-section structure of screw section, anchoring section, and hook section. The anchoring section and hook section are anchored to the hollow cable-passing structure 20, and the screw section passes through the chassis 10 from above and is screwed to the nuts 32. Compared with traditional straight bolts, this design has a stronger anti-overturning ability.
[0035] Moreover, the hollow passageway inside the hollow passage structure 20 allows municipal pipelines 21 to pass directly through, avoiding the encroachment of traditional solid foundations on pipeline layout space, reducing the need for pipelines to detour around motor vehicle lanes, and lowering road construction and subsequent maintenance costs.
[0036] In some embodiments, the lower portion of the hollow cross-pass structure 20 protrudes outward in the horizontal direction. Specifically, this forms an extended foundation structure, expanding the ground surface of the hollow cross-pass structure 20, which provides stronger overturning resistance, as well as pull-out and bending resistance, to the traffic pole foundation, ensuring the stability of the traffic pole.
[0037] In some embodiments, both the anchoring section and the hook section are located within the sidewall of the hollow cable-passing structure 20 and are spaced apart from the cable-passing channel. Specifically, this results in a larger fixing area between the anchor bolt 31 and the hollow cable-passing structure 20, making the connection and fixation between the base and the hollow cable-passing structure 20 more stable, and preventing the anchor bolt 31 from interfering with the cable routing within the cable-passing channel.
[0038] In some embodiments, the length direction of the hollow crosswalk structure 20 extends along the sidewalk or median strip where it is installed. The crosswalk channel runs through the hollow crosswalk structure 20 along its length direction. A row of anchor bolts 31 and nuts 32 is provided on both sides of the hollow crosswalk structure 20 along the road length direction. Specifically, by utilizing the length of the road space to arrange multiple anchor bolts 31 and nuts 32, the connection stability between the hollow crosswalk structure 20 and the base is improved, while avoiding the hollow crosswalk structure 20 being too wide and occupying too much width space on the sidewalk or median strip.
[0039] In some embodiments, each row contains four anchor bolts 31 and four nuts 32, all of M30 size and Q235 strength grade. The anchorage length and bottom bending length of the anchor bolts 31 shall meet the structural requirements of relevant specifications, and the bottom shall be located below the cable passage. Four stirrups are arranged vertically along the anchor bolts 31, with a longitudinal spacing of 15cm.
[0040] In some embodiments, the traffic pole foundation for convenient passage also includes a base flange 11, which is placed between the base 10 and the hollow passage structure 20. Specifically, this rigid connection via the flange converts the bending moment of the column 41 into shear stress between the flange and the concrete, preventing excessive stress concentration at the edge of the base 10, further improving the connection stability between the base and the hollow passage structure 20, thereby extending the service life of the traffic pole foundation.
[0041] In some embodiments, the base flange 11 is rectangular, centrally located on the top surface of the hollow cable passage structure 20, and extends laterally beyond the width of the cable passage, covering part of the sidewall width, thereby meeting the anchoring connection requirements with the anchor bolts 31. The base flange 11 is 120cm long, 120cm wide, and 3.0cm thick, and is made of Q235 steel. The base plate 10 is placed on the base flange 11, with the same shape and dimensions as the base flange 11, a thickness of 3.0cm, and is made of Q235 steel.
[0042] This utility model proposes a traffic pole, including a column 41, a crossbeam 43, functional components, and a traffic pole foundation for easy crossing as described in the above embodiment. The column 41 is installed at the column 41 mounting position, the crossbeam 43 is installed on the upper part of the column 41, and the functional components are installed on the crossbeam 43. The functional components include a signboard 44, a street light, or a traffic signal light.
[0043] Specifically, after the traffic poles are installed on the foundation proposed in this scheme, they will have better anti-overturning ability and stability. Moreover, the reserved passageway can facilitate the direct passage of municipal pipelines 21, avoiding conflicts between the municipal pipelines 21 and the traffic pole foundation.
[0044] In some embodiments, a plurality of stiffening ribs are provided between the column 41 and the beam 43. Specifically, these stiffening ribs can effectively enhance the strength of the connection between the column 41 and the beam 43, improve the overall stability of the structure, and thus enhance the ability of the traffic pole to resist external environmental influences and accidental impacts.
[0045] In some embodiments, eight stiffening ribs are arranged in a ring around the column 41 to improve the stability of the connection between the column 41 and the foundation. The stiffening ribs are 2.0 cm thick, made of Q235 steel, and are right-angled trapezoids with a base width of 15 cm, a top width of 5 cm, an edge height of 7.5 cm, and a height of 20 cm near the column edge. The column base enclosure 46 is made of C20 plain concrete with a thickness of 25 cm, which is 5 cm higher than the column stiffening ribs. To ensure overall aesthetics, a 5 cm thick paving brick is laid on the column base enclosure 46, making it flush with the stepping stone 45 and the sidewalk.
[0046] In some embodiments, a stepping stone 45 is provided on the outer side of the base, and the stepping stone 45 is connected to the upper end of the hollow crosswalk structure 20. The top of the stepping stone 45 is higher than the stiffening rib of the post. Specifically, when located in the median strip, the post base enclosure 46 should not be higher than the stepping stone 45, so that the stepping stone 45 can continue to play its role in protecting the base and the hollow crosswalk structure 20, while maintaining the overall aesthetics of the median strip area and avoiding the post base enclosure 46 protruding and affecting the harmony of the road landscape. When located on the sidewalk, the post base enclosure 46 is paved with paving bricks and is flush with the stepping stone 45 and the sidewalk. This provides pedestrians with a flat and continuous walking surface, avoiding tripping or walking inconvenience caused by height differences, and ensuring the safety and comfort of pedestrians.
[0047] In some embodiments, the top width of the stepping stone 45 is aligned with the width of the side median or sidewalk. This allows for a more rational use of space in the installation of traffic poles, meeting traffic functions while avoiding waste of limited urban space resources. It also aligns with the requirements of compact urban construction and allows traffic facilities to better integrate with the urban environment.
[0048] In some embodiments, the inner side of the step stone 45 is encased in concrete with a column base 46. Specifically, the concrete column base 46 can more tightly connect the column 41 with the step stone 45, base and other structures, increasing the support area and overall rigidity of the bottom of the column 41, thereby improving the stability of the traffic pole under various external forces, enabling it to better resist wind loads, seismic forces, etc., and reducing the possibility of the column 41 swaying or tilting.
[0049] In some embodiments, a maintenance well 50 is provided on the side of the hollow overhead line structure 20. Specifically, this arrangement of the maintenance well 50 facilitates the entry of personnel to conduct regular inspections, maintenance, troubleshooting, and repairs of the line, eliminating the need for large-scale road excavation or dismantling of traffic poles, thus improving maintenance efficiency and reducing maintenance costs.
[0050] In some embodiments, the inspection well 50 is located at both ends of the hollow cable passage structure 20 in the longitudinal direction. It is a square brick or concrete pouring working well with a side length of 100cm. The net size of the inspection well 50 meets the pipeline maintenance requirements.
[0051] The bottom elevation of the maintenance well 50 is 10cm lower than the bottom surface of the passageway. The top surface of the maintenance well 50 is equipped with a concealed manhole cover, which is flush with the elevation of the sidewalk surface.
[0052] In some embodiments, the crossing passage is 60cm wide and 60cm high. The hollow crossing structure 20 is made of C30 reinforced concrete. The distance between the top surface of the crossing passage and the top surface of the sidewalk is 73cm, which meets the minimum soil cover depth requirements in the "Urban Engineering Pipeline Comprehensive Planning Code".
[0053] In some embodiments, the upper part of the hollow crossing structure 20 has a length of 300cm, a width of 150cm, and a height of 160cm. The wall thickness on both sides of the crossing channel is 45cm, the thickness of the crossing channel from the top of the hollow crossing structure 20 is 40cm, and the thickness of the protruding portion at the lower end of the hollow crossing structure 20 is 60cm, with a protrusion dimension of 30cm. Thus, the dimensions of the traffic pole foundation meet the requirements of road plan design and municipal pipeline 21 layout, and the hollow crossing structure 20 meets the overall stability requirements of the signpost structure.
[0054] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
