Road calculus stone using natural stone texture uniform mechanical cutting processing, the strength of stone must be qualified. Road calculus must be linked through the line for the construction, according to the high side of the plane of the top surface of the show marking taut, flat side by stone masonry yard line cable trench cover, flat stone to be safe positive side, avoid laughter, side sleek smooth straight top line, no low wrong tooth phenomenon, not up and down the plane dislocation, both inside and outside the wrong tooth phenomenon. Curbs to prevent dust road, debris is blown or artificially clean sweep in the green man. This results not only affects the health of green cleaning cement-based fiber composite cable trench cover, but the most important is: the long run cable trench cover manufacturers, making this block green gradually increased, and higher than the curb, so rain or water Water rushed on time and put dirt back roads, polluting the environment cement-based cable trench cover, increasing the burden of sanitation workers, in fact, a large part of the green edge of the soil increased by sanitation workers are self-inflicted, and the formation of vicious cycle, disastrous. Cable trench cover manufacturers, Hua Yi Zhongtian (certified), Tianjin, Wuhan, cable trench cover provided by Transit New Material Technology Co., Ltd. overflow.
