路牙石改型后,既可减轻操作人员的劳动强度,又可节约水泥用量5％左右,还可增加排水系统。路牙石长400mm,宽350mm,厚110mm,理论重量约33kg/块。内有φ50的排水孔道(见图1)。路牙石的制作很简单。模具由两根长500～600mmφ50钢管和四块钢模板(钢模壁厚20mm)组成(见图2),紧固件可用其它卡具代替.成型时用一台小型平板振动器,将干硬性砼倒入模具内,稍加振捣密实后,即可置于平整的场地,转动抽出钢管,即可脱去模具,养护10天左右,砼达到75％R_标,即可堆放于仓库内。为了美化环境,还可在两面(一大面一小面),附上彩色砼,成型后即为彩色马路牙。为了提高工效,亦可仿制钢拉模,一次成型4～6块。
After the road tooth stone is modified, it can not only reduce the labor intensity of the operator, but also save about 5% of the cement dosage, and can also increase the drainage system. The road teeth are 400mm long, 350mm wide, and 110mm thick. The theoretical weight is about 33kg/block. There is a Φ50 drainage channel (see Figure 1). The production of road tartar is very simple. The mold is composed of two 500-600mmφ50 steel tubes and four steel templates (steel mold wall thickness: 20mm) (see Figure 2). The fasteners can be replaced by other fixtures. A small flat-plate vibrator is used to mold the mold. After pour into the mold, slightly vibrate and compact, you can place it in a flat place, rotate and extract the steel pipe, then you can take off the mold, maintain for 10 days or so, and reach 75% R_mark, you can stack it in the warehouse. . In order to beautify the environment, it is also possible to attach colored enamels on both sides (one side and one side), and the colored plazas will be formed after molding. In order to improve ergonomics, it can also imitate steel die, forming 4 to 6 blocks at a time.
