Description

Technical Field

[0001] This invention relates to the field of communication pipeline laying technology during road construction, and more specifically, to a road surface communication pipeline fixing device and construction method for preventing damage to communication pipelines. Background Technology

[0002] During highway pavement construction, the electromechanical professionals first laid communication ducts in the central median. Then, the pavement professionals filled and compacted the median with crushed stone and soil to achieve a compaction degree of 0.96. Next, the traffic safety professionals installed guardrail posts on both sides of the median and poured the foundation for anti-glare netting in the center. Finally, the pavement professionals laid permeable bricks on top of the median. The subbase of the pavement used a continuous C20 concrete paving technique. The depth from the top of the subbase to the road surface elevation in the central median area was less than 60 cm. The designed four-hole communication duct was laid in a 2*2 configuration, with the duct occupying a height of 10 cm. The top of the duct was approximately 45 cm from the road surface elevation. In areas with large temperature differences between day and night, some road sections have small curve radii and sharp bends. Before the median strip is backfilled and compacted, the communication pipeline materials are affected by the natural phenomenon of thermal expansion and contraction, causing severe bending deformation and displacement of the pipelines into the guardrail post construction area. At the same time, after the communication pipeline materials are laid bare and before the median strip is backfilled, the communication pipeline materials are easily stolen or damaged. The laying of communication pipelines is a concealed project. After the upper structure of the median strip is covered, if the pipeline is damaged by previous cross-operations and cannot be used, it is difficult to find the pipeline damage point, which seriously affects the construction period. The removal and restoration of the upper structure of the median strip can easily damage and pollute the asphalt pavement.

[0005] To address the shortcomings of existing technologies, this invention provides a road surface communication pipeline fixing device and construction method for preventing damage to communication pipelines, which has advantages and thus solves the problems mentioned in the background technology.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned advantages of good antifreeze effect, the specific technical solution adopted by the present invention is as follows:

[0008] A road surface communication pipeline fixing device for preventing damage to communication pipelines includes a steel mold. The steel mold includes a first side plate and a second side plate. An opening is provided through the bottom surface of the second side plate, and the edge of the second side plate is bent outward to form an ear plate. The first side plate is fixedly connected to the ear plate of the second side plate by detachable bolts.

[0009] Furthermore, both the first side plate and the ear plate have through holes on their surfaces. The detachable bolt includes a bolt body, a nut, an end plate, and a wristband. The bolt body passes through the through hole, and the end plate abuts against the outer wall of the first side plate. The other end of the bolt body is fitted with a nut on one side of the ear plate, and a wristband is welded to the outer wall of the end plate.

[0010] Furthermore, the top opening of the steel mold has a size of 30 cm * 30 cm, and the height of the steel mold is 20 cm. The opening size is 9 cm * 9 cm, and the length between the opening and the ear plate is the same.

[0037] S1: Preparation: First, make multiple steel molds 1 and evenly apply release agent to the inner wall of the steel molds 1. This is a common material and will not be described in detail here. At the same time, clean the median strip roadbed or road surface filling material and pipe trench to facilitate the bonding of concrete with the roadbed, road surface or pipe trench.

[0038] S2: Communication pipeline laying: Two silicon core tubes and two bundled tubes are laid using a special communication pipeline vehicle, which is a common laying equipment.

If a bend is encountered, the binding can be strengthened every 2.5 meters to prevent them from coming apart.

[0039] S3: Steel mold 1 installation: Install one steel mold 1 every 3 meters on average along the pipeline laying direction on site. The bottom surface of the steel mold 1 abuts against the installation surface, and the opening 4 is located on the outside of the pipeline so that the pipeline passes through the opening 4. Keep the steel mold 1 and the binding wire in S2 staggered. If there is a bend, the spacing of the steel mold can be adjusted to 2.5 meters.

[0041] S5: Concrete pouring: C25 commercial concrete is used and transported to the site by a special concrete transport vehicle. After the concrete is poured into steel mold 1, a small vibrator is used for compaction. The compaction time is kept at about 15 seconds, and the small vibrator should not come into contact with the communication pipeline to avoid damage to the communication pipeline. After compaction, the top surface of the concrete is smoothed with a trowel.
