Problems solved by technology
[0005] Based on this, it is necessary for the existing cable trench structure to be backfilled with a large amount of soil, requiring a large amount of land acquisition, high cost, and long time-consuming. A large amount of soil will generate lateral thrust on the cable trench structure, and the additional stress transmitted to the embankment by the soil will be large. and cable trench structure can use less space to provide a cable trench structure, cable laying structure and cable laying method

Embodiment Construction
[0045] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0046]It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes o...

The invention discloses a cable duct structure, which comprises a cushion layer, a bottom plate, a first side plate, a second side plate, a laying device and a cover plate, wherein the bottom plate is arranged on the cushion layer; the first side plate is connected onto one end of the bottom plate and is arranged obliquely relative to the bottom plate to enable the first side plate and an embankment to be fit; the second side plate is arranged at the other end of the bottom plate; the laying device is fixed on the inner side wall of the first side plate and / or the second side plate, and the cable is laid on the laying device; and the cover plate covers the first side plate and the second side plate to seal the cable duct structure. According to the cable duct structure provided by the invention, the backfill soil cover amount is small, the land in need of being occupied is few, the price is low, and the consumed time is short; backfill soil cover does not generate a lateral thrust to the cable duct structure; the problem of a large additional stress transmitted to the embankment by the soil does not exist, and secondary settlement of the embankment is not likely to be generated; and the inner part of the cable duct structure has large utilization space. The invention also discloses a cable laying structure comprising the cable duct structure and a cable laying method.
Description
technical field [0001] The invention relates to the technical field of cable laying, in particular to a cable trench structure, a cable laying structure and a cable laying method. Background technique [0002] When laying high-voltage transmission cables in cities, structures such as cable trenches, buried pipes or cable tunnels are generally selected as the structural forms for protecting cables. When cables are laid beside expressways and railways, economical and reliable cable trench structures are usually selected. [0003] see Figure 1-Figure 3 , the existing commonly used cable trench structure 10 is a square cover plate type cable trench. When constructing, level the site (excavating the foundation trench or not excavating the foundation trench can be done), pour the cushion 11, and pour the bottom plate 12 and the side plate 13, the bottom plate 12 is set horizontally, the side plate 13 is perpendicular to the bottom plate 12, and the 12 and the side plate 13 are i...
