Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of structures of communication pipe under carriageway laying, belong to communication pipe network technical field. BACKGROUND

[0002] With the development of social economy, communication and power pipeline gradually changes from overhead construction to underground construction, and communication and power pipe is usually buried underground along municipal roads and highways. During some construction processes, communication and power pipe needs to be constructed with concrete encapsulation. However, due to the large concrete buoyancy and light pipe, the overall pipe may float during the concrete encapsulation construction process of municipal roads and underground communication and power pipes, which cannot guarantee the construction quality of the pipe.

[0003] Therefore, Chinese patent CN218386564U discloses a power pipe anti-floating device and power pipe system, which includes at least two positioning supports. The grid holes of the fixed frame in each positioning support match the diameter of the power pipe, limiting the power pipe to prevent it from floating and maintaining a stable state, which helps to improve the pouring speed of concrete and avoid blockage during concrete pouring. However, this system requires construction of the cushion layer before construction, which is labor-intensive.

[0004] Based on this, Chinese patent CN220580050U discloses an underground communication and power pipe anti-floating device for concrete encapsulation, which includes a fixed device fixed on both sides of an underground trench. The fixed device is provided with a bolted joint on the upper part, and a pipe is arranged inside the fixed device on both sides. The pipe is wrapped with a wire from the outside, and the ends of the wire are tightly connected with the bolted joints on the upper part of the fixed device on both sides. A plastic hose is provided on the wire to protect the surface of the pipe. In order to maintain and adjust the distance between the pipes and prevent deformation, one or more pipe supports are arranged between adjacent wires. This device does not require pre-fabrication of related structural components before construction, and does not require large material and tooling during construction, achieving low-cost overall construction.

[0005] However, this device needs to add fixed devices, bolted joints, and wires to support the pipe to prevent pipe deformation, which prolongs the construction period of underground communication and power pipes and reduces construction efficiency. UTILITY MODEL CONTENTS
