《压力式侧向流斜板除砂器的设计与应用》(以下简称斜板器)原载《建筑技术通讯》给水排水1980年第三期,现就文中有关问题提出商讨。北京市市政设计院高士国等同志设计的斜板器是在原有扩大管的基础上发展起来的,外形几乎未变,在介绍斜板器的时候,不能全面否定扩大管除砂器。再者,文中没有比较这几种沉砂器的造价。关于造价:一套φ800毫米扩大管沉砂器的工料费共约2700元(直管长8米的),同样长度的φ1200(无斜板)沉砂器只不过5000～6000元,可是加上聚氯乙烯斜板要多花4660元(见附表),如用无毒的聚丙乙烯
“The design and application of pressure type lateral flow swash plate sand remover” (hereinafter referred to as swash plate apparatus) originally contained “Building Technology and Communications” water supply and drainage in the third period of 1980, and the relevant issues in the paper are discussed. The swashplate designed by Gao Shiguo and other comrades of Beijing Municipal Design Institute is based on the original enlarged pipe. The shape is almost unchanged. When the swash plate is introduced, the pipe de-sanding device cannot be completely denied. Moreover, the cost of these sand traps has not been compared. About the cost: A set of φ800mm expansion pipe sander total cost of about 2700 yuan (8 meters long straight pipe), the same length of φ1200 (without swash plate) sand slag just 5000 to 6,000 yuan, but plus PVC sloping board to spend more 4660 yuan (see the attached table), such as the use of non-toxic polypropylene
