Ground surface maintaining device for optical cable landfill route

Abstract

The invention discloses a ground surface maintaining device for an optical cable landfill route. The ground surface maintaining device comprises a device body; and a discharging cavity with a downwardopening is formed in the device body, a pit flattening device is arranged in the discharging cavity and comprises a pressure rod slidably arranged on the right end wall of the discharging cavity, a pressure shaft located below the device body is fixed to the lower side of the pressure rod, and the front side and the rear side of the pressure shaft are rotationally connected with pressure plates.Redundant soil above the optical cable route can be excavated to ensure that the pressure borne by the optical cable route is average, protection of an optical cable is facilitated, the excavated soilcan be subjected to water-spray dust falling, damage to the environment in the transfer process is reduced, the stored soil further ensures that at land sunken positions, the sufficient soil exists for backfilling operation, and the backfilling operation can be completed without excavating soil nearby the sunken positions.

Description

technical field [0001] The invention relates to the technical field of maintenance of buried optical cables, in particular to a surface maintenance device for buried routes of optical cables. Background technique [0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. [0003] Generally, the laying of optical cables is mostly laid by landfill. Since the optical cables are buried underground, the influence factors of receiving the ground are relatively large. If there is too much landfill soil, the pressure received by the optical cables will increase, which is not conducive to the normal operation of the optical cables. Cleaning up the excess soil directly on the ground may cause dust to pollute the environment. At the same time, if there is too little landfil...

Problems solved by technology

[0003] Generally, the laying of optical cables is mostly laid by landfill. Since the optical cables are buried underground, the influence factors of receiving the ground are relatively large. If there is too much landfill soil, the pressure received by the optical cables will increase, which is not conducive to the normal operation of the optical cables. Cleaning up the excess soil directly on the ground may cause dust to pollute the environment. At the same time, if there is too little landfill soil, the optical cable will not be protected normally, which is not conducive to the maintenance of the optical cable. If the soil near the depression is used for backfilling, it will be destroyed. Surrounding environment of backfill
