A kind of cable trench and construction method thereof

Abstract

The invention discloses a cable trench and a construction method thereof. The cable trench comprises a cable trench unit, a well cover plate and a fixing frame; the well cover plate comprises a main cover plate, a handle groove is formed in the main cover plate, an opening handle is arranged in the handle groove, a locking device is arranged between the main cover plate and the fixing frame, the locking device comprises a lock hook and a lock catch, the lock hook and the opening handle are linked through a linkage device, the linkage device comprises an adjusting rod provided with an adjustingpiece, a semi-circular positioning piece is arranged on the lock hook, the adjusting rod is matched with the positioning piece, so that the locking hook and the lock catch can be opened only when theopening handle rotates towards the inside of the handle groove. The lock hook and the lock catch are arranged below the main cover plate, so that people cannot easily damage the locking device from the outer side to open the main cover plate, the method for opening the well cover plate is difficult to find by using the conventional thinking of outward pulling of the handle, the main cover plate can be opened conveniently and quickly by an operator, and the cable trench is anti-theft device and is convenient to open.

Description

technical field [0001] The invention relates to the technical field of cable construction engineering, in particular to a cable trench and a construction method thereof. Background technique [0002] With the progress of the society and the continuous development of the economy, people's requirements for communication are constantly improving, but the old-fashioned high-altitude pull net has many defects, which speeds up the construction of underground cable communication facilities. At present, underground cables are constructed by excavating first, then laying, and then covering. The cover is usually a cable trench cover made of multiple cement boards, and the cables are covered under it by laying in sequence. Although this kind of laying is simple in construction and convenient for cable maintenance in the later stage, due to the high economic value of the cable, such a simple laying method prompts some criminals to easily open the cover to steal the cable, which not only...

Problems solved by technology

[0004] However, the fixing structure of the bolt and the self-locking nut is simple and clear, and it is easy to disassemble, and the fixing structure is directly exposed in the lock hole above the interlocking plate, which cannot effectively prevent theft. It is connected by side plugging, it is difficult to open when they are compact with each other, and it is inconvenient to operate
