Problems solved by technology

The cable trench cover plate used in this structure is designed as a multi-layer structure. Although the mechanical strength of the cover plate can be enhanced, the design process is complicated, and the matching dimensions of the bracket, steel wire layer, and cover plate need to be controlled at the same time, resulting in high cost.

Embodiment 1

[0033] like figure 1 As shown, the present invention discloses a cable trench, which includes a trench body and a cover plate 1 arranged on the upper end of the trench body. The cable support 4 is arranged on the top, and the cable support 4 adopts the structure in the prior art to be arranged in rows;

[0034] The cover plate 1 is a reinforced concrete structure, the upper end surface of the cover plate 1 is an arc-shaped structure, and a support frame is arranged inside the cover plate. The support frame includes an outer frame 5 and a plurality of arch supports arranged in the outer frame 5, and the arch supports are equally spaced. Arranged in rows; the arch support includes a lower support rod 6 fixedly connected to the outer frame, an upper support rod 7 fixed at both ends of the lower support rod 6, a plurality of vertical rods between the lower support rod 6 and the upper support rod 7 8. The upper support rod 7 is an arc-shaped structure. In specific use, anti-slip ...

Embodiment 2

[0040] combine figure 1 and figure 2 As shown, the present invention discloses a cable trench, which includes a trench body and a cover plate 1 arranged on the upper end of the trench body. Cable brackets are arranged on the top, and the cable brackets adopt a rotatable structure and are arranged in rows;

[0041]The cover plate 1 is a reinforced concrete structure, the upper end surface of the cover plate 1 is an arc-shaped structure, and a support frame is arranged inside the cover plate. The support frame includes an outer frame 5 and a plurality of arch supports arranged in the outer frame 5, and the arch supports are equally spaced. Arranged in rows; the arch support includes a lower support rod 6 fixedly connected to the outer frame, an upper support rod 7 fixed at both ends of the lower support rod 6, a plurality of vertical rods between the lower support rod 6 and the upper support rod 7 8. The upper support rod 7 is an arc-shaped structure.

[0042] The structure ...

Embodiment 3

[0045] The structure of this embodiment is basically the same as that of Embodiment 2, the difference is: as image 3 As shown, the structure of the cable support is limited, two extension springs 12 are mounted symmetrically on the cable support seats of the three cable support seats 11 on the same cross bar 9 , and the lower ends of the extension springs 12 are articulated with the cross bar 9 . During the cable laying process of this structure, the two tension springs 12 arranged symmetrically can prevent the free rotation of the cable support base 11 and improve the construction efficiency in the cable laying process.

Abstract

The invention belongs to the technical field of electric power facilities, in particular to a cable ditch. The cable trench comprises a trench body and a cover plate arranged on the trench body, the cover plate is a reinforced concrete structure, a support frame is arranged in the cover plate, the support frame comprises an outer frame and a plurality of arch supports arranged in the outer frame,and the arch supports are arranged in rows. The invention carries out special design on the internal structure of the cover plate, utilizes the principle of the arch bridge, adopts the support frame formed by welding very few steel materials, and provides the cover plate with sufficient bearing force to support the passage of the heavy-duty machinery, the service life can be up to several years, and when the cover plate is actually used in the substation, the effect is obvious, and the investment cost is low.

Description

technical field [0001] The invention belongs to the technical field of electric facilities, in particular to a cable trench. Background technique [0002] The cable trench is an underground pipeline for laying and replacing electric power or telecommunication cable facilities, and it is also an enclosure structure for the cable facilities to be laid. There are rectangular, circular, arched and other pipeline structures. The layout of cable trenches in power plants and substations is related to field equipment and terrain conditions, but both indoor and outdoor cable trenches generally have the following characteristics: [0003] (1) The cable trench is a trench with a cover plate, and the cover plate must be uncovered when laying and maintaining cables, which is very cumbersome and inconvenient, and dirt and water are easy to accumulate in the trench. However, due to the simple civil construction and low cost, it is often used in substations and small and medium-sized power...
