Electric cable well

Abstract

The invention discloses an electric cable well. The electric cable well comprises a body and electric cables, wherein the electric cables are independently distributed in the electric cable well; when the number of the electric cables is large, the electric cables are independently distributed in the electric cable well in a parallel mode; an intelligent on-line monitoring and early-warning system used for the operation conditions of the electric cables is arranged in the electric cable well and comprises a monitoring terminal and a monitoring center master station, and the monitoring terminal is arranged on the site of the electric cables and is connected to the monitoring center master station through a wireless network. Compared with the prior art, the electric cable well has the advantages that the structure is reliable, the utilization rate of space is high, the safety factor is high, maintenance and safety problems caused by disorder of electric cables in wells on the existing market can be avoided, maintenance is convenient and fast, faulted electric cables can be found fast when breakdowns occur and maintained in time, and charged electric cables and uncharged electric cables can be separated so that the construction safety can be further guaranteed.

Description

technical field [0001] The invention relates to an underground wiring device in urban construction or electric power construction and an installation method thereof, in particular to a cable well. Background technique [0002] Existing sewage wells, rainwater wells, rainwater wells, gas valve wells, power cable wells, all kinds of weak current cable wells and other types of public pipeline equipment wells are usually built with bricks and other masonry, or cast-in-place at the installation site. Method made of concrete for equipment wells. Among them, 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 b...

Problems solved by technology

In the prior art, the spare cables for each circuit, regardless of the incoming and outgoing cables, will be uniformly wound into circles and stacked in the same cable well. At this time, the cables may be intertwined and even knotted, so the spare cable needs to be used in case of cable failure. When the cables are stacked, it is not possible to straighten out the spare cables quickly, and it is difficult to pull out the spare cables for maintenance and troubleshooting in a timely manner, especially when the cables are stacked together, it is very difficult to find the bottom cable, which is relatively heavy and often requires the help of external tools , the fault delay is long, the maintenance and fault handling are inconvenient, and the use of cables is delayed

In addition, when a cable in one loop fails, the cables in other loops will also be affected, and there may be joint failures; more importantly, live and dead cables may be placed in the same cable shaft at the same time, causing problems during construction and maintenance. Multiple potential safety hazards, especially when there is water accumulation in the well, the liveliness will be more dangerous

What's more, it is neither safe nor convenient to construct under the foundation where outdoor equipment has been installed, especially the construction space is extremely small, and it will be difficult to escape in the event of an accident

[0004] In addition, 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-base salt erosion, and lose waterproof ability, easy to penetrate, poor durability, and low strength. Reduced and 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

Moreover, a large number of clay bricks are used to cause a waste of clay resources, which is not in line with environmental protection policies; what's more, with the current structure, when checking some special requirements of cables, the bricks must be knocked off before inspection, which is a waste of time and It is labor-intensive, and after the overhaul, you have to lay bricks again, which causes 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
