Communication optical cable well and construction method thereof

Abstract

The invention discloses a communication optical cable well and a construction method thereof. The optical cable well comprises a lower semicircle cylinder, an upper semicircle cylinder and a well cover, wherein the upper semicircle cylinder and the lower semicircle cylinder are connected together, and the well cover is installed on the upper semicircle cylinder; a first reinforcing rib is installed at the bottom of the lower semicircle cylinder, and a second reinforcing rib is installed on the inner wall of a cylinder body formed by connecting the lower semicircle cylinder and the upper semicircle cylinder; and the upper semicircle cylinder is provided with a wire inlet and a wire outlet which are oppositely arranged, the inner wall of the upper semicircle cylinder is provided with clamping devices, and the two clamping devices are oppositely arranged; and the communication optical cable well is arranged in a pre-digging groove, and hollow rubber air bags are filled with a gap betweenthe pre-digging groove and the communication optical cable well. According to the method, the communication optical cable well is high in anti-pressure ability, and the situation that normal work is affected by occurring of water leakage due to the deformation of the pre-digging groove is avoided; and meanwhile, by dividing the well wall of the communication optical cable well into the upper semicircle cylinder and the lower semicircle cylinder, the construction difficulty is reduced, and the dismounting and the maintenance are convenient.

Description

technical field [0001] The invention belongs to the field of optical communication equipment, and in particular relates to a communication optical cable shaft and a construction method thereof. Background technique [0002] With the continuous growth of information transmission volume and broadband business demand and the demand for fiber-to-the-home construction, the laying area of ​​optical fiber communication lines is becoming more and more extensive, which directly leads to a substantial increase in the use of optical communication equipment. It is an important part of the optical communication network. [0003] In order to save the space resources on the ground, the optical communication network is generally laid underground through the pipeline network. The communication optical cable well is an important part of the optical communication underground network. Generally, a communication optical cable well is set at a certain distance to facilitate the staff. In the pri...

Problems solved by technology

[0003] In order to save the space resources on the ground, the optical communication network is generally laid underground through the pipeline network. The communication optical cable well is an important part of the optical communication underground network. Generally, a communication optical cable well is set at a certain distance to facilitate the staff. In the prior art, communication cable shafts are generally built with bricks. This type of cable shaft is low in cost and easy to construct, but due to material limitations and simple structure, it is easily affected by geological conditions and external environmen
