Description

Technical Field

[0001] The utility model relates to the field of concrete cable trenches, in particular to a prefabricated concrete cable trench. Background Art

[0002] Precast concrete cable trenches are prefabricated in factories and then transported to the site for installation. They are fast to install, have stable quality, and can reduce project cycles and costs. Cable trenches are underground pipelines used to lay and replace power or telecommunication cable facilities. They are also the enclosure structure for the laid cable facilities. They have rectangular, circular, arched and other pipeline structure forms.

[0003] A Chinese patent discloses a prefabricated concrete cable trench (authorization announcement number CN 215498207 U). The patented technology enables the utility model to use a prefabricated integrated U-shaped concrete trench body and a prefabricated concrete cover plate, combined with on-site assembly, to quickly lay the cable trench directly on site, simplifying the construction process and greatly improving the overall construction efficiency. In addition, the laying of the U-shaped concrete trench body at the front and rear ends can be achieved through the docking between the convex portion and the concave docking portion, and the docking between the docking convexity and the docking groove, ensuring that the front and rear two prefabricated U-shaped concrete trench bodies are spliced ​​flat, stable and tight, ensuring the quality of the laying construction; however, the device is somewhat laborious when installing the concrete cover, and is not easy enough for the installation of the cable.

[0004] Therefore, those skilled in the art provide a prefabricated concrete cable trench to solve the problems raised in the above background technology. Utility Model Content
