Description

TECHNICAL FIELD

[0001] The utility model relates to municipal road technical field, concretely relates to a road side flat stone and pedestrian isolation fence structure based on prefabricated assembly technology, be applicable to the municipal road that has the need of side flat stone and pedestrian isolation fence arrangement. BACKGROUND

[0002] At present, in order to ensure the traffic safety of pedestrians and prevent pedestrians from crossing the road at will, most urban roads take the measure of setting pedestrian isolation fences.

[0003] In the current national standard "Urban Road Traffic Facilities Design Specification" (GB 50688-2011) and public safety industry standard "Urban Road Traffic Isolation Fence Setting Guide" (GA / T 1567-2019) in China, the setting of pedestrian isolation fences on urban roads is clearly regulated: pedestrian isolation fences should be set up where there is a height difference between the sidewalk and the ground on one side, and there is a risk of pedestrians falling; pedestrian isolation fences should be set up on the outside of the bridge sidewalk; pedestrian isolation fences should be set up along the side flat stone at the entrances of stations, piers, commercial centers and large public places, as well as at the edges of the vehicle road in areas with heavy pedestrian traffic such as pedestrian overpasses and tunnel staircases; pedestrian isolation fences should be set up at the edges of crosswalks and other areas where pedestrians need to be prevented from crossing the motorway, but they should be disconnected at pedestrian crossings.

[0004] As can be seen from the above, pedestrian isolation fences are generally set along side flat stones when used to isolate vehicles and pedestrians, and both of them are physical separation facilities that isolate vehicles and pedestrians. Compared with side flat stones, pedestrian isolation fences also have the functions of preventing pedestrians from crossing at will and being easily discovered by drivers.

[0005] Currently, pedestrian isolation fence construction is often carried out after the sidewalk has been constructed, with the posts located near the side flat stones on the sidewalk. This not only makes construction inconvenient and time-consuming, but also encroaches on the sidewalk space.

[0006] Therefore, a new pedestrian isolation fence installation technology needs to be designed to solve the above problems. SUMMARY

[0007] The utility model aims at the deficiencies of the prior art, and provides a road side flat stone and pedestrian isolation fence structure based on prefabricated assembly technology. During the prefabrication of the side flat stone, a hole for the pedestrian isolation fence post is reserved in advance, so that the pedestrian isolation fence does not need to be drilled and installed on the sidewalk during construction, but can be directly installed on the side stone. The prefabricated side flat stone is used as a fence foundation, which reduces the construction difficulty and time, makes full use of the space, and ensures the width of the sidewalk.

[0008] The utility model achieves the purpose by the following technical solutions:

[0009] The utility model relates to a road side flat stone and pedestrian fence structure based on prefabricated assembly technology, characterized in that: including side stone, flat stone and side flat stone foundation, the side stone and the flat stone are prefabricated as integrated structure, integrated structure of prefabricated by the side stone and the flat stone is installed on the side flat stone foundation, the side stone is as the foundation of guardrail column, and it is provided with the reserved hole hole matched with the guardrail column, and the pedestrian fence is installed through the guardrail column.

[0010] The reserved hole hole is filled with cement mortar, and the guardrail column is fixed in the reserved hole hole through the cement mortar.

[0011] The side stone, the flat stone and the side flat stone foundation are prefabricated as an integrated structure.

[0012] The reserved hole hole without inserting the guardrail column is sealed by cement mortar pouring and keeps flush with the surface of the side stone.

[0013] The utility model has the advantages of:

[0014] (1) the side stone flat stone and the foundation adopt concrete integrated prefabrication as the foundation of pedestrian fence, which is more conducive to the integrity and stability of the side flat stone and the fence;

[0015] (2) the distance between the pedestrian fence columns is 2m, which is the commonly used specification, and the width and height of the side stone and the reserved hole hole can meet the commonly used guardrail column specification, so that the pedestrian fence does not need to be specially customized in principle, and the investment is simple and the performance is reliable;

[0016] (3) the main construction method is basically the same as the current construction method of guardrail, and the technology is mature and the construction is convenient;

[0017] (4) the reserved hole hole facilitates the construction of the pedestrian fence, reduces the process and saves the construction period. BRIEF DESCRIPTION OF DRAWINGS

Reserved hole 8. Sidewalk 9. Roadway 10. Cement mortar 11. Guardrail post 12. Curbstone 13. Reserved hole 14. Cement mortar 15. Guardrail post 16. Upper structure of pedestrian guardrail 17.

[0023] Example: Figure 1 As shown, the roadside stones and pedestrian guardrail structures based on prefabrication assembly technology in this embodiment are suitable for the prefabrication of side stones for newly built roads or roads that need to be renovated or expanded.

[0024] The structure in this embodiment includes a side stone 1, a flat stone 2, and a side-flat stone foundation 3. The side stone 1 and flat stone 2 are precast as a single unit using C30 concrete, while the side-flat stone foundation 3 is cast-in-place using C30 concrete. Pre-drilled holes 4, matching the guardrail posts, are provided on the side stone 1.

[0025] During the prefabrication of side stones, holes for pedestrian guardrail posts are pre-reserved, so that the pedestrian guardrails do not need to be drilled on the sidewalk during construction. Instead, they can be directly installed on the side stones, using the prefabricated side stones as the foundation for the guardrails. This reduces construction difficulty and time, and makes better use of space to ensure the width of the sidewalk.

[0026] like Figure 1 As shown, in this embodiment, L1, L2, H1, and H2 are the dimensional setting parameters for the side stone foundation 3, and L3 and H3 are the width and depth setting parameters for the reserved hole 4, as detailed below:

[0027]

[0029] The guardrail post 12 is inserted into the reserved hole 8 and fixed with cement mortar 11. The guardrail post 12 is used to install the isolation barrier between the sidewalk 9 and the roadway 10 to ensure safety.

[0030] In this embodiment, the specific indicators and parameters of each component are as follows:

[0031]

[0032]

[0033] like Figure 3As shown, after the construction of the pedestrian isolation fence is completed, the reserved holes not inserted with the fence posts are plugged and the achievement is accepted, the main structure includes curbstone 13, reserved hole 14, cement mortar 15, fence post 16, pedestrian isolation fence upper structure 17, wherein the pedestrian isolation fence upper structure 17 is installed between the fence posts 16.

[0034] In the embodiment, the specific indexes and parameters of each component are as follows:

[0035]

[0036] The embodiment has the following construction method:

[0037] (1) The distance between the pedestrian isolation fence posts and the length of the curbstone are kept in an integer multiple relationship, the size of the curbstone is 100cm*40cm*20cm, the size of the curbstone is 100cm*30cm*15cm, the distance between the pedestrian isolation fence posts is 2m, and the height of the isolation fence should not exceed 1.2m.

[0038] (2) The reserved hole in the middle of the upper side of the curbstone should have a size and depth that can meet the depth required for inserting the pedestrian isolation fence post into the foundation.

[0039] (3) The curbstone and the curbstone are prefabricated with the concrete foundation as a whole.

[0040] (4) When the pavement is constructed, prefabricated concrete curbstones are arranged on both sides of the road section along the line where the fence is needed.

[0041] (5) After the construction of the curbstone is completed and before the fence is arranged, it is necessary to check whether the reserved hole in the curbstone is clean and free of debris.
