Description
Technical field
The present invention relates to a kind of electric power transmission apparatus field, specifically a kind of composite material cable ditch.
Background technology
Cable trough is the most common structures of specializing in cabling or installation accessories at present, how to install fast and efficiently, and smoothly by the acceptance of work, avoid the generation of the situation of doing over again, and more and more becomes the focus that everybody pays close attention to.According to the difference of the degree of depth, cable trough can be divided into two types, when the degree of depth is not more than 1m, adopts brick setting surface plastering cable trough, mostly adopts cast-in-place concrete cable trough while being greater than 1m.
Brick cable trough is because brick technological requirement of plastering is higher, and the quality of plastering is generally on the low side, easily occurs common quality defect; The globality of brick cable trough and less stable, normal occur tilting, collapse, the problem such as distortion.There is formwork difficulty in cast-in-situ steel reinforced concrete cable trough, ditch body concrete surface smoothness is difficult to be guaranteed, and furrow bank protective layer is thinner, affected by multigelation, and after use for many years, surface fracture is serious, and inconvenience is repaired; Cable trough furrow bank rough surface, construction wrong easily produces corner angle, easy damaged cable covering in cabling process.Above-mentioned two kinds of cable troughs are because resource cost is more, and situ wet operation procedure is many, and construction period is longer, and safety construction is poor, can not adapt to the requirement of current power engineering construction.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of composite material cable ditch, this composite material cable groove structure is stable, easy for installation, and can prevent that cable covering from sustaining damage.
For achieving the above object, the technology used in the present invention means are as follows: a kind of composite material cable ditch, comprise some interconnected main bodys, this main body is made up of composite material, this main body comprises base plate and the side plate that is assembled in these base plate both sides, and the body inner surface at adjacent this interconnected position of main body is level and smooth.
The body inner surface at the interconnected position of aforementioned body is the level and smooth two kinds of situations that mainly comprise.The first situation is in the time that the body inner surface at the interconnected position of aforementioned body forms the corner angle of projection, and the edges and corners that the interconnected position of this main body forms are set to fillet; The second situation is that the body inner surface at this interconnected position of main body is positioned at same plane in the time that the body inner surface at the interconnected position of aforementioned body does not form the corner angle of projection.
