Plastic power cable well

Abstract

The invention relates to an electric power building or construction technology, in particular relates to a cable well with acid-alkali resistance and durability. The cable well comprises a box-shaped well body, wherein the well body comprises an internal metal frame and a shell, wherein the shell is arranged at the outer part of the metal frame, is made of plastics and is provided with a cable inlet, a cable outlet and a manhole or a hand hole; reinforcing ribs are uniformly arranged on the inner surface and / or the outer surface of the shell in a staggered manner; and due to adoption of the structure with the internal metal frame and the external plastic shell, the metal frame supports the shell, and simultaneously, the reinforcing ribs distributed on the surface of the shell in a staggered manner further guarantees the structural strength of the shell. The cable well has the advantages that the structural strength is reliable; and simultaneously, the plastic shell and the reinforcing ribs on the shell enable the shell to have certain flexibility, and the vibration and the pressure can be absorbed and buffered. The cable well has the characteristics of high water discharging efficiency, acid-alkali-salt corrosion resistance, suitability for use under various geological conditions, strong earthquake resistance and long service life, and obtains great economic and social benefits.

Description

technical field [0001] The invention relates to electric power construction or construction technology, in particular to a cable well. Background technique [0002] The cable well is an underground inspection well that plays the role of installation or maintenance during construction and after the completion of the project in the cable laying project. It is generally divided into manhole well and hand hole well. The manhole well is relatively large, and people can go down into the well for construction operations. The hand hole well is generally relatively small, and only the hand can be reached in for operation. It is generally used on branch lines, and there are not many cables passing through the well. , easy threading. Most of the traditional cable wells are made of brick or concrete. [0003] However, practice has proved that the existing brick or concrete cable wells buried in the ground are easily corroded and peeled off by wet soil, water vapor, moisture immersio...

AI Technical Summary

Problems solved by technology

[0003] However, practice has proved that the existing brick or concrete cable wells buried in the ground are easily corroded and peeled off by wet soil, water vapor, moisture immersion, acid, alkali and salt erosion, and lose waterproof ability, easy to infiltrate, poor durability, and reduced strength. , easily damaged; since cable wiring and cable wells are set along both sides of the road, once such a cable well is damaged, it will affect the smooth traffic of urban roads and is not conducive to the protection of groundwater resources.

[0004] And a large number of clay bricks are used to cause a waste of clay resources, which does not comply with environmental protection policies. Moreover, with the current structure, when inspecting cables, the bricks must be knocked off before inspection, which is a waste of time and labor. Laying bricks again will cause a lot of waste

Or in the structure of using the manhole cover to close the cable well, the structural strength of the manhole cover is insufficient, and it is inconvenient to use
