Embodiment 1

[0030] Embodiment one: as attached Figure 5 to attach Figure 7 As shown, a cable well includes a bottom plate 6 , a side wall 7 and a cover plate 8 enclosing the space in the well, and also includes a cushion 9 and a cable support 10 . The cable well includes four side walls 7, which are respectively a pair of opposite connecting side walls 7 and a pair of opposite supporting side walls 7, and the connecting side walls 7 are used for connecting cable pipes. The cushion layer 9 is disposed under the bottom plate 6 .

[0031] The bottom plate 6 has an overhanging portion 11 protruding from the outer edge of the side wall 7 along the extending direction of the cable duct, so that the bottom plate 6 constitutes an extended bottom plate 6 . The cable conduit also includes a balance portion 12 arranged on the outstretched portion 11 of the bottom plate 6 and used for balancing stress and supporting the cable conduit. The balance part 12 is formed by flakes or plain concrete, an...

Abstract

The invention relates to a cable working well which comprises a bottom plate, a side wall and a cover plate which define a space in the well, the side wall is used for being connected with a cable duct bank, the bottom plate is provided with an outwards-extending part extending out of the outer edge of the side wall in the extending direction of the cable duct bank, and the cable duct bank furthercomprises a balance part arranged on the outwards-extending part of the bottom plate and used for balancing stress and supporting the cable duct bank. According to the invention, the problem of differential settlement between the cable duct bank and the cable working well can be well solved, the construction is convenient, the period is short, and the required investment is less.

Description

technical field [0001] The invention belongs to the technical fields of electric power engineering and municipal engineering, and in particular relates to a cable well. Background technique [0002] According to the laying requirements of power cables, a cable well (including cable inspection wells or branch wells) must be installed at a certain distance along the length of its path (generally no more than 100m), and the internal clearance of the well must meet the cable laying requirements. 1. The needs of inspection and maintenance, subject to the requirements of people’s maintenance, the inner clearance height of the well is not less than 1.9m. After taking into account the thickness of the covering soil and the bottom plate structure, the depth of the bottom plate of the well is at most more than 2.5m. Considering the cable laying in the well, personnel maintenance, etc. Requirements, the width and length of the well are generally not less than 1.6m and 2.5m. At this ti...
