Description

Technical Field

[0001] The utility model belongs to the technical field of municipal pipeline protection, and specifically relates to a municipal pipeline protection device. Background Art

[0002] There are many different pipelines laid under municipal roads, such as electricity, communications, gas, water supply, drainage pipes, etc. With the continuous construction of buildings and roads in the city, it is necessary to excavate the road surface, then bury the pipelines below the surface for connection, and finally fill them back with soil.

[0003] When existing municipal pipelines are installed, they are usually buried directly underground. During use, if the ground needs to be excavated, it is easy to cause damage to the pipelines. Therefore, some pipelines will add protective devices to protect them. However, most of the existing pipeline protection devices use spliced ​​cement pipes. The pipelines to be protected are passed through the laid cement protection pipes and then directly buried with soil. When this protection method is actually used, due to the poor toughness of the cement protection pipes themselves, they will break or crack when heavy vehicles pass through the road or under long-term compression of soil, etc., allowing underground soil and moisture to enter the interior of the cement protection pipes, causing erosion to the internal pipelines; in addition, due to gravity reasons, the municipal pipelines will be located at the bottom of the cement protection pipes, and when the cement protection pipes crack or leak, the external soil or accumulated water will bury or soak the pipelines completely, which will still cause corrosion to the pipelines, and the protection effect is poor.

[0007] As an improvement, two ends of the bottom of the top bracket are bent inwards and fixedly connected to one end of the sliding connection groove through the cooperation of a first bolt and a nut.

[0008] As an improvement, a threaded sleeve connected to the screw rod through threads is arranged in the middle of the limit frame, and both ends of the bottom of the limit frame are bent outwards and fixedly connected to the sliding connection groove through the cooperation of a second bolt and a nut.

[0009] As an improvement, a hexagonal nut is provided on the screw rod above the connecting platform, and a fastening nut is provided on the screw rod between the connecting platform and the limiting frame.

[0010] As an improvement, the plurality of support rods are located at equal angles between the wire support frame and the bottom bracket, and the connection points between the plurality of connecting rods and the wire support frame are at the same position as the plurality of support rods.

[0011] As an improvement, the support bracket matches the shape of the wire supporting rack, and the support bracket is located between the two wire supporting racks.
