Reinforced plastic cable wells

Abstract

The invention relates to the technology of electric power construction or construction, in particular to an electric cable well which is acid-resistant, alkali-resistant and durable. The electric cable well comprises a box-shaped well body, wherein the well body comprises a metal frame and a shell; the metal frame is arranged in the well body; the shell is arranged outside the metal frame and is made of plastic; a wire inlet, a wire outlet and a human hole or a hand hole are formed in the shell; reinforcing ribs are uniformly arranged in the shell and / or on the outer surface of the shell in a staggering mode. Due to the fact that the electric cable well is of the structure that the metal frame is arranged in the well body and the shell is arranged outside the metal frame, the metal frame supports the shell, and meanwhile, the reinforcing ribs are arranged on the outer surface of the shell in a staggering mode, so the structural strength of the shell is further guaranteed. The electric cable well with such structure is reliable in structural strength; meanwhile due to the fact that the reinforcing ribs are arranged on the plastic shell and the shell, the shell has certain flexibility, and shock and pressure can be better absorbed and buffered; the electric cable well has the characteristics of high water draining efficiency, acid resistance, alkali resistance, salt corrosion resistance, suitability for multiple geological conditions, high earthquake resistance and long service life; important economic 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
