Prefabricated cable trench and construction method thereof

Abstract

The invention relates to a prefabricated cable trench and a construction method thereof. The prefabricated cable trench comprises two prefabricated calandrias, a bottom connecting plate and a top connecting plate; the ends of the two prefabricated calandrias are sequentially connected in a continuous mode in the linear direction, first assembling grooves are formed in the bottoms of the outer pipewalls of the prefabricated calandrias, and second assembling grooves are formed in the tops of the outer pipe walls of the prefabricated calandrias; the bottom connecting plate is provided with two first assembling convex bodies which are arranged in a spaced mode, and the first assembling convex bodies are inserted into the first assembling grooves in a one-to-one correspondence mode; and the top connecting plate is provided with two second assembling convex bodies which are arranged in a spaced mode, and the second assembling convex bodies are inserted into the second assembling grooves ina one-to-one correspondence mode. Compared with a traditional cast-in-place concrete cable trench, the prefabricated cable trench does not need to carry out operation contents such as steel bar binding, template building and concrete pouring on site, the workload and the labor intensity of constructors can be greatly reduced, meanwhile, the construction period is greatly shortened, the influence of different skill levels of the constructors is avoided, and the forming quality of the prefabricated cable trench can be ensured.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a prefabricated cable trench and a construction method thereof. Background technique [0002] At present, with the rapid advancement of urbanization, municipal road construction is also in full swing, among which the underground cable laying work for connecting different public equipment and power supply equipment is the most basic and important construction content. In order to protect underground cables, it is usually necessary to dig foundation pits on the ground first, lay cable trenches in the foundation pits, then lay underground cables in the cable trenches, and protect the underground cables through the cable trenches. [0003] However, most of the cable trenches used on the market are still cast-in-place concrete cable trenches. The construction of this type of cable trench requires a series of complicated processes such as concrete mixing, steel bar bind...
