Cable wells resistant to acid, alkali and salt corrosion

Abstract

The invention discloses an acid, alkali and salt corrosion-resistant and high-low-temperature-resistant cable well, and relates to an electric power construction or construction technology, in particular to an acid and alkali-resistant durable cable well. The cable well comprises a box-shaped well body, wherein the well body comprises an internal metal framework and a shell arranged outside the metal framework; the shell is made of plastic; the shell is provided with a wire inlet hole, a wire outlet hole and a man hole or a hand hole; reinforcing ribs are uniformly arranged in the shell and / or on the outer surface in a staggered way; a structure with the internal metal framework and the external plastic shell is adopted, the metal framework supports the shell, and meanwhile the reinforcing ribs are arranged on the surface of the shell in a staggered way, so that the structural strength of the shell is further ensured. The cable well is reliable in structural strength; meanwhile, the shell is made of plastic and the reinforcing ribs are arranged on the shell, so that the shell has certain flexibility, and vibration and pressure can be better absorbed and buffered; the cable well has the characteristics of high drainage efficiency, resistance to acid, alkali and salt corrosion, suitability for use under various geological conditions, high earthquake resistance and long service life; great economical and social benefits are achieved.

Description

[0001] This application is a divisional application of the invention patent with the application number: 201210046209.2 and the patent name: "A Plastic Power Cable Well". The original application date: 2012-2-28. technical field [0002] The invention relates to electric power construction or construction technology, in particular to a cable well. Background technique [0003] 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 ar...

Problems solved by technology

[0004] 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.

[0005] 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
