Embodiment 1

[0040] Such as figure 1 and figure 2 As shown, the communication optical cable well includes a bottom well 1, a lifting casing 2 and a water storage barrel 3. The side wall of the bottom shaft 1 has a connection area 1a. The lifting casing 2 is slightly larger than the bottom shaft 1 so that the lifting casing 2 can be set outside the bottom shaft 1 and can go up and down. The shape of the lifting casing 2 and the bottom shaft 1 is identical to ensure that the lifting casing 2 is set on the bottom shaft 1, and the circumferential gap size between the inner wall of the lifting casing 2 and the outer wall of the bottom shaft 1 is consistent. Such as figure 1 and figure 2 As shown, the cross-sectional shape of the lifting casing 2 and the bottom shaft 1 is a rectangle.

[0041] The gap between the lifting casing 2 and the bottom shaft 1 is not more than 8mm. This value can not only ensure that the lifting casing 2 can be conveniently placed outside the bottom shaft 1, but ...

Embodiment 2

[0054] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is: after the communication optical cable pipe 8 passes through the hole in the side wall of the bottom shaft 1, then between the communication optical cable pipe 8 and the side wall of the bottom shaft 1 Filled with sealant, the structure and process can significantly reduce the amount of water infiltration.

Embodiment 3

[0056] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that: Figure 5 and Figure 6 As shown, the communication optical cable shaft also includes a takeover sealing ring 11 made of rubber. The outer surface of the takeover sealing ring 11 has an annular sealing groove 11a, and one end of the takeover sealing ring 11 is a constricted sealing lip 11b.

[0057] Take over the sealing ring 11 in the construction method of the communication optical cable well, and install between the hole that is drilled on the side wall of the bottom shaft 1 and the hole that the communication optical cable pipe 8 passes through the side wall of the bottom shaft 1 . In other words, first put the connecting pipe sealing ring 11 through the hole opened on the side wall of the bottom shaft 1, and the edge of the hole in the side wall of the bottom shaft 1 is embedded in the annular sealing groove 11a, so that the connecting pipe sealin...

Abstract

The invention provides a communication optical fiber cable well and a method for constructing the communication optical fiber cable well, and belongs to the technical field of fixing buildings. The communication optical fiber cable well and the method solve the problem that the construction period of an existing concrete-poured communication optical fiber cable well is long. The communication optical fiber cable well comprises a bottom well body and a lifting sleeving well body. Pipe connecting areas are arranged on the side walls of the bottom well body. The lifting sleeving well body is in a straight sleeve shape, is arranged on the outer side of the bottom well body in a sleeved mode and can be vertically lifted. The method for constructing the communication optical fiber cable well includes the steps of slotting, foundation manufacturing, communication optical fiber cable well installing, pipe connecting and backfilling. The communication optical fiber cable well is molded by plastic in an injection mode and has the advantage of being convenient to process. The intensity of the plastic communication optical fiber cable well is effectively guaranteed by arranging reinforcing ribs and adopting arc angle transition between the side walls, and the communication optical fiber cable well meets the project requirements. After the communication optical fiber cable well is pressed by a heavy object, the bottom well body is not prone to damage and sinking, and the communication optical fiber cable well has the advantages of being long in service life and high in water seepage resistance. The communication optical fiber cable well further has the advantages that the communication optical fiber cable well is convenient to construct, and the construction period is remarkably shortened.

Description

technical field [0001] The invention belongs to the technical field of fixed buildings, and relates to a well, in particular to a communication optical cable well. [0002] The invention belongs to the technical field of fixed buildings, and relates to a communication optical cable well, in particular to a construction method for a communication optical cable well. Background technique [0003] Communication optical cable is one of the important components in the communication network system. In order to save space resources on the ground and keep the city clean and orderly, an underground communication pipe network is laid underground, and communication optical cables are laid along the communication pipe network. The communication optical cable well is an important part of the underground communication pipe network, and a communication optical cable well will be set at a certain distance to facilitate the laying and maintenance of the communication optical cable. [0004...
