Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a cable trench cable protection structure. Background Art

[0002] In municipal road projects, newly built municipal branches or secondary trunk roads often need to be connected to other existing roads, and the completed cable trenches need to be protected from vehicles passing through. Since the cable trenches bear the load of pedestrians and vehicles passing on the road and the cables have been laid, it is impossible to add casing protection. Traditional protection methods are mostly concrete encapsulation. Once the cables are damaged in this way, they cannot be maintained or replaced. Additional lines need to be added, and they are prone to electric shock and power outages. The safety is poor, so further improvement is needed.

[0003] After searching, the Chinese announcement number is: CN211922684U. A buried cable trench protection structure includes an original cable trench, excavating foundation soil on both sides of the original cable trench to form cavities on both sides, setting a concrete foundation cushion layer on the foundation soil at the bottom of the cavity, pouring a strip foundation on the concrete foundation cushion layer, and setting a cover plate on the end face of the strip foundation to form a protection structure for the original cable trench. When the road passes through the cable trench, the utility model can not only effectively protect the cable trench, but also avoid power outages and ensure the safety of pedestrians, and has important economic and social benefits.

[0004] The above patent mentioned in the specification that "the foundation soil on both sides of the original cable trench is excavated to form cavities on both sides, a concrete foundation cushion is set on the foundation soil at the bottom of the cavity, a strip foundation is cast on the concrete foundation cushion, and a cover plate is set on the end face of the strip foundation to form a protection structure for the original cable trench. When the road passes through the cable trench, the utility model can not only effectively protect the cable trench, but also avoid power outages and ensure the safety of pedestrians." However, in the actual use process, when vehicles or heavy objects pass by, coarse sand will fall on the outer layer of the cable and cause scratches. Over time, the surface of the cable will be damaged, and the cable cannot be protected. For this reason, a cable trench cable protection structure is proposed. Utility Model Content

The interior of the concrete layer 6 is fixedly connected with multiple clamps 4, and the clamps 4 are set every 2m. Through such a design, a variety of fixing effects can be provided for subsequent workpieces. The interior of the clamp 4 is fixedly connected with the plastic-coated steel pipe 3. The clamp 4 is in two U shapes, and a number of bolt holes are opened on the clamp 4. The two arc-shaped halves of the plastic-coated steel pipe 3 are buckled and connected by installing bolts in the bolt holes. The bolts can be installed in the bolt holes, thereby achieving the ability to fix the plastic-coated steel pipe 3;

[0027] The plastic-coated steel pipe 3 is a tubular body composed of two arc-shaped half-bodies buckled together, with a diameter of not less than 150mm and a thickness of not less than 4mm. This design ensures the pipe's performance in terms of load-bearing and durability. It adopts a socket connection, which is simple and effective and can be quickly installed and maintained. The filling is on the outside of the plastic-coated steel pipe 3, with a thickness of not less than 500mm. The surface coating of the plastic-coated steel pipe 3 is not less than 250um thick. This coating provides protection against environmental corrosion and extends the service life of the pipe.

[0028] A shielding layer 2 is fixedly connected to the inside of the plastic-coated steel pipe 3, and multiple cables 1 are fixedly connected to the inside of the shielding layer 2. The shielding layer 2 is designed mainly to prevent electromagnetic interference and protect the integrity of the internal cables 1. The cables 1 are existing cable trench cables 1, which are made of one or more mutually insulated conductors and an outer insulating protective layer. These cables 1 are mainly used to transmit electricity or data, and play a key role in industrial equipment control, communication systems or building power distribution.

[0029] Working principle: according to the requirements of the drawings, the cable trench is removed in the passing section, the existing cables in the cable trench are wrapped with PE open-edge pipes, fixed with 600mm long cable ties, and fixed with steel wire ropes. One end is fixed on the surrounding fence for suspension protection to avoid damaging the cables and causing personal electric shock or large-scale power outages. By laying plastic-coated steel pipes 3 in the trench, the cables are slowly placed into the plastic-coated steel pipes 3, and the middle is separated by pipe pillows. The plastic-coated steel pipes 3 are connected with sockets, and the ports are equipped with waterproof rubber rings. Bolts are installed in the bolt holes of the clamps to buckle the two arc-shaped halves of the plastic-coated steel pipes 3 together, and the outside of the plastic-coated steel pipes 3 is connected. It is encapsulated with C30 concrete, filled densely, with a thickness of not less than 500mm to meet the load of passing vehicles, thereby protecting the cable. When the cable 1 needs to be protected by the signal, the shielding layer 2 effectively blocks the interference of the external electromagnetic field on the internal signal of the cable 1, thereby ensuring the stability and reliability of the signal transmission. Especially in high-frequency transmission, the shielding layer 2 can significantly reduce crosstalk and other forms of interference. The two concrete layers 6 are designed to protect the cable 1 from moisture at the bottom and top, and can effectively prevent groundwater or moisture in a humid environment from penetrating into the interior of the cable 1.
