mso-hansi-font-family:"Times New Roman"">一、产品概述:
mso-hansi-font-family:"Times New Roman"">常水头土壤渗透仪仿照基马式渗透仪制造,内径尺寸该为φ100+0.22mm可测定砂类土及含少量砾石的无凝聚性土在常水头下进行渗透试验。
mso-hansi-font-family:"Times New Roman"">二、常水头土壤渗透仪主要技术参数:
1、筒身内径:φ100+0.22mm
2、渗水筒高度:400mm
3、测压管间距离:100 mso-hansi-font-family:"Times New Roman"">±.44mm
mso-hansi-font-family:"Times New Roman"">注:全套仪器及附件、备件包括:
mso-hansi-font-family:"Times New Roman"">渗水部件、木锤、管夹、测压管、橡皮管(长1.5 mso-hansi-font-family:"Times New Roman"">米)各一件,铜丝网0.5 "Times New Roman"">×0.6(20 mso-hansi-font-family:"Times New Roman"">#)、1 "Times New Roman"">×1(40 mso-hansi-font-family:"Times New Roman"">#)各二块。
mso-hansi-font-family:"Times New Roman"">三、常水头土壤渗透仪结构及原理:
mso-hansi-font-family:"Times New Roman"">本仪器主要由渗水部件和击实部分组成。渗水部件由筒身、渗水板、刻度板、测压管等组成,在刻度板上装有三个测压管,其间距为100 mso-hansi-font-family:"Times New Roman"">±0.44mm "Times New Roman"">,水位的测读可由安装在筒上的刻度板的刻度读出,测压管接头内均装有铜丝布以防止细砂粒在试验时随水流出。渗水筒下部有一排水孔,松开螺栓即可放出污水。击实部分备有木锤,以击实试样。
mso-hansi-font-family:"Times New Roman"">四、常水头土壤渗透仪依据标准:
mso-hansi-font-family:"Times New Roman"">仪器设计制造符合(GB9357-77 "Times New Roman"">)标准,符合《土工试验规程》(SL237-1999 "Times New Roman"">)《公路土工试验规程》(T0129-93 "Times New Roman"">)中的砂类土及含少量砾石的无凝聚性土在常水头下进行渗透试验。
