Description

Technical Field

[0001] This utility model relates to the field of municipal road pole assembly engineering, and in particular to a composite pole foundation and pole assembly installation structure. Background Technology

[0002] Combined poles (also known as "multi-pole integration" or "smart combined poles") are an intensive construction model that integrates various functional poles (such as streetlights, traffic signal poles, monitoring poles, and signposts) scattered along urban roads into a unified pole body. This aims to solve the problem of "numerous poles" and improve urban space utilization efficiency and management. Existing combined pole foundations are reinforced concrete structures, and their construction process includes: surveying and positioning - excavation - rebar tying - bolt joint installation - formwork installation - concrete pouring and curing - formwork removal - backfilling - pole installation - grouting at connection ends. The disadvantages are that the reinforced concrete combined pole foundation involves numerous construction steps and a long concrete pouring and curing period; during excavation, the large excavation area results in a large foundation footprint and deep excavation depth. Due to the influence of the excavation area and depth, it is difficult to avoid all underground pipelines in the complex geological environment, potentially damaging some underground pipelines and making excavation difficult. Utility Model Content

[0003] The purpose of this utility model is to provide a composite foundation and a composite installation structure to solve the problems of long construction period, low efficiency, large earthwork excavation area, and deep excavation depth of single composite foundations in reinforced concrete structures, which may easily damage some underground pipelines in complex underground pipeline geological environments.

[0004] To solve the above-mentioned technical problems, this utility model provides a composite foundation, comprising:

[0005] The pile foundation is constructed by inserting it into the soil along the ground level, with the ends of the pile foundation sinking below the ground level.

[0006] A shallow pit concrete foundation is constructed around the pile foundation at a predetermined depth below the end of the pile foundation to fix the pile foundation.

[0007] Furthermore, the composite foundation provided by the present invention comprises steel pipe piles inserted downward into the soil along the ground level.

[0008] Furthermore, in the composite foundation provided by the present invention, the steel pipe pile is filled with granular filler.

[0009] Furthermore, in the composite foundation provided by the present invention, the filler is yellow sand.

[0010] Furthermore, the composite foundation provided by the present invention comprises steel pipe concrete piles inserted downwards into the soil along the ground level.

[0011] To solve the above-mentioned technical problems, this utility model also provides a rod mounting structure, including:

[0012] Composite foundation;

[0013] The composite rod is connected to the pile foundation of the composite rod foundation via flanges and bolts;

[0014] A graded crushed stone layer is laid on a shallow pit concrete foundation;

[0015] The slab layer is laid on the graded crushed stone layer; the connection between the composite rod and the pile foundation is located at the junction of the graded crushed stone layer, the slab layer, or both.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model provides a composite foundation and installation structure for a combined pole, which improves upon the traditional single-pole foundation of concrete structures by transforming it into a composite foundation composed of pile foundations and shallow pit concrete foundations. The pile foundations, extending deep into the soil, bear the gravity load of the combined pole, while the shallow pit concrete foundations at the ends of the pile foundations fix them in place, preventing loosening at the ends that could affect the load-bearing capacity of the combined pole and avoiding the safety risk of the combined pole tipping over. This improves the construction quality of the composite foundation. By using shallow pit concrete foundations instead of traditional deep pit concrete foundations, the amount of earthwork excavation is reduced, as are the horizontal excavation area and vertical excavation depth. This results in advantages such as smaller footprint and volume, effectively reducing conflicts with surrounding underground pipelines and the risk of damage. Furthermore, the shallow pit concrete foundations reduce the amount of concrete poured, shorten the construction period, and improve the overall construction efficiency of the composite foundation.

[0018] The combined rod installation structure provided by this utility model has the connection between the combined rod and the pile foundation located at the graded crushed stone layer, the ground layer, or the junction of the two, and is prohibited from being located in the shallow pit concrete foundation. This can improve the convenience of later maintenance and construction of the connection node between the combined rod and the pile foundation. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0030] Please refer to Figures 1 to 3 This utility model embodiment provides a composite foundation 110, including a pile foundation 111 and a shallow pit concrete foundation 112, wherein:

[0031] The pile foundation 111 is inserted into the soil downwards along the ground level, with its end sinking below the ground level. The pile foundation 111 can be a steel pipe pile, such as... Figure 1 As shown; it can be a steel pipe pile filled with granular materials such as yellow sand, such as Figure 2 As shown; it can also be a steel-concrete composite pile formed by pouring concrete into a steel pipe pile, such as Figure 3 As shown. Among them, the steel pipe piles and steel-concrete piles filled with yellow sand can further improve the structural strength of the pile foundation 111.

[0032] A shallow pit concrete foundation 112 is constructed around the pile foundation 111 at a predetermined depth below the end of the pile foundation 111, and is used to fix the pile foundation 111. That is, the pile foundation 111 is exposed on the upper surface of the shallow pit concrete foundation 112.

[0033] The composite foundation provided in this embodiment improves upon the traditional single composite foundation 120 of concrete structure into a composite foundation 110 consisting of a pile foundation 111 and a shallow pit concrete foundation 112. The construction process is as follows: measurement and positioning - steel pipe pile insertion - composite installation - grouting at a predetermined depth below the connection point. This simplifies the construction process. The pile foundation 111, which extends deep into the soil, bears the gravity load of the composite foundation 120. The pile foundation 111 is fixed by a shallow pit concrete foundation 112 at the end of the pile foundation 111 to prevent the pile foundation 111 from loosening at the end and affecting the load on the composite foundation 120, thus avoiding the safety risk of the composite foundation 120 tipping over and improving the construction quality of the composite foundation 110. By constructing a shallow pit concrete foundation 112 instead of a traditional deep pit concrete foundation, the amount of earthwork excavation is reduced, as are the horizontal excavation area and vertical excavation depth. This has the advantages of small footprint and small volume, effectively reducing conflicts with surrounding underground pipelines and reducing the risk of damage to underground pipelines. At the same time, the shallow pit concrete foundation 112 reduces the amount of concrete poured, shortens the construction period, and improves the overall construction efficiency of the composite foundation 110.

[0034] Please refer to Figures 1 to 3 This utility model embodiment also provides a composite pole installation structure 100, including: a composite pole foundation 110, a composite pole 120, a flange 130, a graded crushed stone layer 140, and a floor layer 150, wherein:

[0035] The composite foundation 110 is composed of the composite foundation 110 described in the above embodiment, the pile foundation 111, and the shallow pit concrete foundation 112.

[0036] The composite rod 120 is connected to the pile foundation 111 of the composite foundation 110 of the composite rod 120 via flange 130 and bolts.

[0037] A graded crushed stone layer of 140 is laid on a shallow pit concrete foundation of 112.

[0038] The ground layer 150 is laid on the graded crushed stone layer 140; the connection between the composite rod 120 and the pile foundation 111 is located at the junction of the graded crushed stone layer 140, the ground layer 150, or the two. The ground layer 150 can be a brick layer, a soil layer, a sand layer, a vegetation layer, etc.

[0039] The combined rod installation structure 100 provided in this embodiment of the utility model has the connection between the combined rod 120 and the pile foundation 111 located at the junction of the graded crushed stone layer 140, the ground layer 150, or the two, and is prohibited from being located within the shallow pit concrete foundation 112. This can improve the convenience of later maintenance and construction of the connection node between the combined rod 120 and the pile foundation 111.
