Abstract

The invention discloses a prefabricated cable channel and a preparation method thereof. The prefabricated cable channel is poured by flow-state ultrahigh-performance inorganic powder concrete, and the flow-state ultrahigh-performance inorganic powder concrete is prepared from the following raw material components in parts by weight: 500-650 parts of low-alkaline portland cement or portland cement, 85-120 parts of silica fume, 115-145 parts of II-level fly ash, 175-215 parts of slag powder, 1050-1250 parts of river sand, 26-32 parts of high-efficiency water reducing agent, 130-145 parts of water, and 100-140 parts of straight copper-plated steel fiber. The prefabricated cable channel is attractive in appearance, high in crush resistance and breaking strength and light in weight, and the weight of the prefabricated cable channel is one third to one fifth of the weight of a channel poured by common concrete or concrete.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a prefabricated cable trench and a preparation method thereof. Background technique [0002] Power prefabricated trenches in China have always been built with traditional brick masonry or on-site concrete. In recent years, research and development of prefabricated cable trenches has been carried out, especially in Jiangsu, Zhejiang and other places. The main reason is that the geological conditions are relatively poor and there are many quicksand silt geology , Excavation and construction are difficult. In recent years, due to maintenance, renovation and other reasons in large developed cities in China, in order to reduce traffic and other impacts and speed up the construction progress, they have also begun to test and start using them. After more than ten years of exploration and research and development, various Various forms of prefabricated trenches, such as large-scale mono...
