Description
Technical field
The present invention relates to building material field, particularly relate to a kind of pre-fabricated electric cables ditch and preparation method thereof.
Background technology
It is traditional brick masonry or employing on-site concrete that electric power prefabricated ditch China adopts always, this starts to carry out exploration research and development pre-fabricated electric cables ditch for several years, particularly Jiangsu, zhejiang and other places, main cause is that geologic condition is poor, drift sand mud geology is more, excavation construction difficulty is larger, domestic large-scale flourishing city was due to maintenance in recent years, the reasons such as transformation, for reducing traffic and other influences, accelerating construction progress also starts exploration and brings into use, successively various forms of prefabricated ditch is proposed through the exploration of more than ten years and research and development, such as large-scale monolithic concrete builds cable trench, the cable trench etc. that various organic resin is made, really the amount of coming into operation is also few, reason is really wanted to be, concrete placement pre-fabricated electric cables groove, well deadweight is excessive, require higher to the process on basis and bearing pressure, foundation settlement dislocation etc. is there will be in use procedure, construction needs Large-scale Hoisting equipment in addition, the more difficult enforcement of assembled movement, and the cable trough using organic resin to make easily compressive deformation in backfilling process and in later stage use procedure, therefore domestic a lot of city is attempting exploring the pre-fabricated electric cables ditch how developing the high-strength light excellent in durability being effectively applicable to engineering always.
Application number be 200910060802.0 Chinese patent " a kind of low cost active powder concrete and preparation method thereof " disclose a kind of RPC, the silicate cement, steel-making slag powder, flyash, silicon ash, high efficiency water reducing agent, river sand, mixing water and the steel fiber that are 0.52 ~ 0.58: 0.16 ~ 0.18: 0.10 ~ 0.16: 0.13 ~ 0.16: 0.012 ~ 0.018: 0.9 ~ 1.1: 0.14 ~ 0.18: 0.156 ~ 0.234 by mass ratio obtain.This patent adds slag as a kind of mineral admixture, at the early stage the resistance of concrete to chloride ion penetration of concrete lower than straight cement concrete, the resistance of concrete to chloride ion penetration in later stage is higher than straight cement concrete, but when identical volume, the performance of slag is not as good as flyash and slag, in addition, in slag, a small amount of CaO exists in a free form, and f-CaO aquation generates Ca (OH)
2, volume increases 1.98 times, causes steel slag stability bad.
