L-shaped concrete cable trench prefabricated component and production technology

Abstract

The invention relates to an L-shaped concrete cable trench prefabricated component and the production technology. The L-shaped concrete cable trench prefabricated component comprises an L-shaped concrete body; side wall force bearing ribs in the height direction and side wall distribution ribs in the length direction are arranged inside the side wall; bottom plate force bearing ribs in the width direction and the bottom plate distribution ribs in the length direction are arranged inside the bottom plate of the concrete body; one end of the bottom plate force bearing rib is connected to the the side wall force bearing rib; a connection segment is formed and projected from the inner side surface of the other end of the bottom plate force bearing rib; half-circle grooves are reserved on the front end and the rear end of the concrete body for installing water encounter swelling water stop bars; an upper iron member and a lower iron member are pre-embedded on the front end and the rear end of the side wall of the concrete body; and convex lugs arranged on two sides of the iron member are provided with bolt holes. The invention has better adaptability and flexibility than the current U type prefabricated component, has better manufacture cost, transportation cost, hoisting cost and maintenance cost.

Description

technical field [0001] The invention relates to an L-shaped concrete cable trench prefabricated part and a production process thereof, belonging to the technical field of cable trenches. Background technique [0002] The traditional cable trench is generally a brick structure or cast-in-place concrete structure. For a long time, it has been used to purchase sand, bricks, steel bars, cement and other construction materials on site, and bind steel bars on site, formwork, mix concrete, pour, maintain, Masonry fills walls and traditional patterns such as stucco. Although it has a long history and mature technology, it has its own insurmountable shortcomings. For example, the strength of the brick cable trench is low, the manual masonry construction is heavy, and the construction process is not in place, resulting in quality defects and cracks in the trench; while the construction period and maintenance time of the concrete cable trench are long, and it is impossible to construc...
