Problems solved by technology

However, U-shaped prefabricated cable trenches still have many disadvantages: the size is fixed, and specific molds need to be developed for each trench size, which is difficult to reduce the cost. Secondly, the U-shaped trench is bulky and inconvenient to transport, which further increases the construction cost

Abstract

The invention relates to a concrete prefabricated groove. The concrete prefabricated groove comprises a groove body. The groove body is formed through opposite lap joint of two L-shaped components in parallel. A sewer pipe is perpendicular to the bottom of the groove body and is arranged at the lap joint position of the two L-shaped components. The upper portion of the groove body is covered with a cover plate. The concrete prefabricated groove can adapt to different cable trench widths, and the research and development number of dies is reduced. The size is small, the concrete prefabricated groove is easier to tidy and stack during transportation compared with U-shaped components, and the transportation cost is effectively reduced; and assembling is flexible, and the concrete prefabricated groove can adapt to the arrangement of different lines.

Description

technical field [0001] The invention relates to a construction prefabricated structure, in particular to a concrete prefabricated trench. Background technique [0002] With the acceleration of the construction of modern international cities, urban power lines and communication lines are gradually transferred from the ground to the ground. In order to bury cables, generally there must be a U-shaped cable trench (or cable trench) in the cross section. A cable support protrudes from the side wall, and a cover plate is also provided on the wire trench. [0003] Traditional cable trenches often use brick-laying cable trenches or cast-in-place concrete cable trenches, and the cable brackets are directly embedded in the wall during masonry. Since the main material of masonry is solid clay red brick, it causes waste of land resources and is a non-degradable resource consumption product, which has been gradually limited or even banned in large, medium and small cities. Moreover, on...
