Description

Concrete prefabricated part for laying underground cable

Technical Field

The utility model relates to a precast concrete component technical field specifically is a precast concrete component for underground cable lays.

Background

The precast concrete members are building members, including beams, plates, columns, building finishing accessories and the like, which are manufactured in advance in factories by using concrete as a basic material. Is used for assembly on construction sites and is a material foundation for building industrialization. The prefabricated concrete member is fabricated before installation in a construction site, and generally comprises a prefabricated concrete floor slab, a concrete box girder for a bridge, a prefabricated concrete roof beam for an industrial factory building, a culvert frame structure, a prefabricated concrete pile for foundation treatment and the like. Also comprises a structural member used for laying electric power cable equipment underground and the like.

With the acceleration of the construction process of modern cities, urban electric power and communication lines are gradually shifted from the ground to the underground, cable ditches (or called cable troughs) are mostly adopted in power transmission and transformation projects for burying cables, the traditional cable ditches are generally brick-built or cast-in-place concrete cable ditches, and the cables are erected in the ditches by using supports made of section steel.

The traditional cable trench is basically a bricklaying cable trench and a cast-in-place concrete cable trench, and a cable support is directly buried in a wall body during bricklaying. The main material of the masonry is solid clay red bricks, which causes waste of land resources, and the masonry is a non-degradable finished product with resource consumption, and is gradually used in large, medium and small cities with limited quantity or even prohibited use. And moreover, the cable trough is built on site, so that various raw materials are difficult to manage, the engineering construction efficiency is low, the construction period is long, the cost is high, and the strength is low. The cast-in-place concrete cable trench has long construction period and maintenance period, construction in winter in cold areas is limited, meanwhile, the requirement on the site construction process is high, and the quality problems of components are easily caused by the fact that the construction process does not reach the standard or the working procedures are not strict.
