A communication optical cable well and a construction method for the communication optical cable well

Abstract

The invention discloses a communication optical cable well and a construction method for the communication optical cable well, comprising a well cover arranged at the notch of the well groove, a base arranged on the inner bottom surface of the well groove and a well casing sleeved on the side wall of the well groove. The upper and lower end surfaces of the well casing are respectively connected with the well cover and the base, and the well casing includes a cylindrical protective sleeve and a connecting sleeve. The upper and lower surfaces of the connecting sleeve are provided with two coaxial annular grooves. Protective sleeves are provided on the upper and lower sides of the connecting sleeve, one end of the protective sleeve extends into the annular groove, and the annular outer surface of the protective sleeve is attached to the inner wall of the annular groove, and the bottom surface of the protective sleeve below is in contact with the top surface of the base. contact, the top surface of the other protective sleeve is in contact with the bottom surface of the manhole cover, and the manhole cover includes a fixing frame covering the top of the notch of the well groove and a cover plate located below the fixing frame. The invention is detachably connected by components such as a well cover, a well casing, a base, etc., which is convenient for disassembly and assembly, saves the construction time of the communication optical cable well, and reduces the construction cost.

Description

technical field [0001] The invention relates to the field of communication engineering, in particular to a communication optical cable well and a construction method for the communication optical cable well. Background technique [0002] At present, 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. Optical cable wells are an important part of optical communication networks. [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 dist...

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, the communication cable wells are generally built with bricks. Although the construction is convenient, it wastes a lot of manpower. Due to material limitations and simple structure, it is easily affected by geological conditions and external environments. The problem of cracks on the side wall of the well occurred, followed by the problem of water seepage and leakage, which had a serious impact on the preservation of the optical cable connection parts and the maintenance environment of the staff. In order to improve this problem, people also use concrete, cement and other materials to repair the inner wall of the optical cable well, but the construction period is long, the cost is high, and it is not easy to repair in the later stage. In order to solve this problem, a construction method for the communication optical cable well and the communication optical cable well is proposed
