mso-hansi-font-family:"Times New Roman"">三、操作说明：

1 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、将仪器安放在水平的平台上。

2 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、接上电源，按数显器面板上的“ mso-hansi-font-family:"Times New Roman"">电源” "Times New Roman"">键，数显窗即显示数码。请通电10 "Times New Roman"">分钟后，使数显值自动趋于“0” "Times New Roman"">。

3 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、选装上合适的贯入针。350N mso-hansi-font-family:"Times New Roman"">对应初凝贯入阻力（即2~3.5Mpa, "Times New Roman"">此时用100 mm2 "Times New Roman"">贯入针）；1000N "Times New Roman"">对应中间贯入阻力（即3.5~20Mpa, "Times New Roman"">此时用50 mm2 "Times New Roman"">贯入针）；560N "Times New Roman"">对应终凝贯入阻力（即20~28Mpa, "Times New Roman"">此时用20mm2 "Times New Roman"">贯入针）。

4 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、料模中装满待测试的砼试料，抹平后放于仪器底板上。

5 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、调整贯入深度。

mso-hansi-font-family:"Times New Roman"">混凝土贯入阻力仪一种方法是：先量出贯入针下端面与试料上平面的距离X mso-hansi-font-family:"Times New Roman"">（注意：X "Times New Roman"">不得大于5mm "Times New Roman"">，否则需适当下调贯入针），再将仪器顶部的定长螺母下平面与“ "Times New Roman"">盖” 宋体;mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">的上平面距离调整到25+Xmm mso-hansi-font-family:"Times New Roman"">，然后再拧紧螺盖，以锁住25+X "Times New Roman"">长度。

mso-hansi-font-family:"Times New Roman"">另一种方法是：压下手柄使贯入针下端面与试料上平面保持平齐，然后调整仪器上部的定长螺母，使之下平面与“ mso-hansi-font-family:"Times New Roman"">盖” "Times New Roman"">的上平面距离调到25mm "Times New Roman"">并锁住这一长度，再松开手柄。

mso-hansi-font-family:"Times New Roman"">以上两种方法的实际贯入深度均为25mm mso-hansi-font-family:"Times New Roman"">。

6 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、测试。首先按数显面板上的清零键清除传感器的初值，即清零。再按测试键进入工作测试状态，同时数显板上第一个灯（测试灯）亮, mso-hansi-font-family:"Times New Roman"">握住手柄向下转动，使贯入针接触试料至贯入到最深位置（25mm mso-hansi-font-family:"Times New Roman"">）的过程控制在10 "Times New Roman"">秒钟左右。此时数显出现峰值, "Times New Roman"">同时数显板上第二个灯（峰值灯）亮, "Times New Roman"">读出数显器的显示值，做好纪录，一次测试完成。

mso-hansi-font-family:"Times New Roman"">初凝时，使用1 cm2 "Times New Roman"">贯入针，计算公式为：P=N&pide;100 "Times New Roman"">（MPa 宋体;mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">）；

mso-hansi-font-family:"Times New Roman"">终凝时，使用0.2 cm2 "Times New Roman"">贯入针，计算公式为：P=5 N&pide;100 "Times New Roman"">（MPa 宋体;mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">）。

mso-hansi-font-family:"Times New Roman"">四、混凝土贯入阻力仪试验规程：

1 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、混凝土放于仪器底盘上，松开调节螺套，选装上合适的贯入针。

2 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、旋动调节螺塞使压力表指针对准刻度零线。

3 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、将动作钮子开关置于调整位置，将正反转钮子开关置于正转位置，按工作按钮后试料容器在2 mso-hansi-font-family:"Times New Roman"">秒后。开始上升，待停止以后，即可调整。调整时拧松调节螺套将贯入针调至刚好接触试料面，拧紧调节螺套固定贯入针。再按动动工作按钮，10 mso-hansi-font-family:"Times New Roman"">秒钟以后试料容器升高25mm "Times New Roman"">，即贯入到最深位置，读取压力表贯入阻力并记录，试料容器停留4 "Times New Roman"">秒钟以后，开始下降，7 "Times New Roman"">秒钟后恢复原位。自动停机，一次测试完成。

4 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、作第二次贯入测试时必须变换贯入位置，推动手柄使其旋转一定角度，当贯入点在外圈时，变化测点只需推动手柄一次；当贯入点在内圈时，变化它则需推动手柄二次。

5 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、在测试过程中，应经常注意压力表指针起始是否在零位，如不在零位应调零。

6 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、在不需调整贯入针高低时，可将动作纽子开关置于自动位置，这样在以后的测试中只要按启动按纽一次，即自动作一次测试循环。

7 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、每个试样作贯入阻力试验应不少于六次，最后一次的单位面积贯入阻力应不少于28MPa mso-hansi-font-family:"Times New Roman"">。

8 mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">使用一段时间后，旋动调节螺塞至极限位置不能使压力表指针调到零线，此时必须添加油液。

mso-hansi-font-family:"Times New Roman"">五、注意事项：
