Problems solved by technology

This device solves the problem that the previous protection mechanism only protects the two sides and the upper part of the cable, and the lower part is easily affected by moisture and corrosion. It can disperse and slow down the pressure from the outside to prevent the cable from being compressed. It also provides a rubber material with great Good resilience performance, corrosion resistance, fire resistance and flame retardant performance, high mechanical strength, excellent comprehensive performance, and prolong the service life of the cable. However, there is no monitoring during the construction process of the cable laying, and the construction is inconvenient

Embodiment 1

[0035] like Figure 1-2 As shown, the present embodiment provides a method for safely laying underground cables, comprising the following steps:

[0036] S1: Investigate the terrain and the presence or absence of obstacles in the section where the cable line passes, check and record the length of each section;

[0037] S2: Pouring protective foundation;

[0038] S3: Excavating cable trenches;

[0039] S4: Implant the protective foundation and lay cables.

[0040] In the step S3, the excavation depth of the cable trench is 1-1.5m. In case of obstacles or areas with shallow permafrost, it should be deepened appropriately: the corner of the cable trench should be dug into an arc shape, and the allowable bending radius of the cable should be ensured: where the cable joint is introduced into the building or from the pole The residual pit for spare cable margin shall be dug out.

[0041] In the step S4, the bottom plate is implanted first, then cables are laid, the cover plate ...

Embodiment 2

[0043] like Figure 1-2 As shown, this embodiment provides a method for safely laying underground cables, which is an improvement on the basis of Embodiment 1:

[0044] In the step S2, the protection foundation is formed by pouring concrete.

[0045] The protective foundation includes a cover plate 6, a base plate 1, and two side plates 5 arranged at both ends of the base plate 1; the base plate 1 is provided with a first support plate 4, and the cover plate 6 is provided with a second Support plate 7.

[0046] The bottom plate 1, the side plate 5 and the first support plate 4 are formed by one-time pouring, and the cover plate 6 and the second support plate 7 are formed by one-time pouring.

[0047] Two first support plates 4 are arranged on the bottom plate 1 , and the cable is located between the two first support plates 4 .

[0048] Two second support plates 7 are arranged on the cover plate 6 , and when closed, the two second support plates 7 are respectively located b...

Embodiment 3

[0055] like Figure 1-2 As shown, this embodiment provides a method for safely laying underground cables, which is an improvement on the basis of Embodiment 2:

[0056] In the step S4, the bottom plate is implanted first, then cables are laid, the cover plate is implanted, and soil is taken for backfilling.

[0057] Lay a layer of fine sand with a thickness of 2-3cm between the two first support plates, and then lay the cable, after that, lay fine sand on the surface of the cable, at the same height as the first support plate, the first support plate and the side plate A layer of fine sand with a thickness of 2-3cm is also laid in between, and the cover plate is implanted, compacted, backfilled with soil, and compacted.

Abstract

The invention provides an underground cable safe laying method, and belongs to the technical field of power cables. The method comprises the following steps: S1, surveying the terrain and the existence of obstacles of a section where a cable line passes through, and checking and recording the length of each section; S2, pouring a protection foundation; S3, digging a cable trench; and S4, implanting a protection foundation, and laying cables. The mehtod is stable in structure, and the technical problem that a cable cannot be effectively protected through an existing cable laying method is solved. The cable is comprehensively protected by the protection foundation, small animals can be prevented from damaging the cable, and the underground cable can be prevented from being corroded; meanwhile, in the cable laying construction process, reasonable laying is achieved, a good damping effect is achieved, construction is convenient and rapid, the service life of the underground cable is effectively prolonged, and the maintenance frequency of the underground cable is remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a method for safely laying underground cables. Background technique [0002] With the rapid development of urbanization, life is becoming more and more intelligent, so more electricity needs to be consumed. In order to avoid the huge impact of power outages on life, many cables have also moved from the original overhead to more and more underground. Due to the increase of load, self-aging, and some construction units' weak awareness of the protection of power facilities during the construction process, the brutal construction leads to frequent failures of the cable and the normal power supply and other factors. The hidden danger of external damage has always threatened the safe operation of the cable line. . The existing cable underground burying technology generally installs underground cables in pipelines without other protective treatment, which is extremely easy to be ...
