土工合成材料垂直渗透仪使用方法： 

★将试样置于含湿润剂的水中，至少浸泡12h直至饱和并赶走气泡。湿润剂采用0.1%V/V的烷基苯*酸钠。    

★取下高压仓（见仪器间图12）安装试件（5）于夹持器（6），试样要求：试样应清洁，表面无污物，无可见污物或折痕，不得折叠，并应放置于平处，上面不得施加任何荷载。然后安装好高压仓，依次平衡力拧紧高压仓螺母。

★打开通水阀（3）由（1）注入清洁水源**压水罐（2）。直至两侧水位达到50mm的水头差（11）。关掉供水，如果试样两侧的的水头在5min内不能平衡，查找是否有未排干净的空气。打开（13）排气阀门重新排气。并在试验报告中注明。

★调整水流，使水头差达到70mm±5mm，记录此值。**到1mm。待水头稳定30s后在规定的时间周期内，用量筒收集（8）渗透水收集管通过的渗透水量，体积**到10mL，时间**到s，收集渗透水量1000mL，时间至少30s。

★分别对A大水头差0.8, 0.6, 0.4和0.2倍的水头差。重复以上2.3.4的程序，从A高流速开始到A低流速结束，并记录下相应的渗透水量和时间。

★记录水温，**到0.2℃。

★结果的计算请依据T1141-2006的相应标准。

Use of geosynthetics vertical infiltration meter:

★ Place the sample in water containing humectant and soak it for at least 12 hours until it is saturated and remove the air bubbles. Wetting agent was 0.1% V / V sodium alkylbenzenesulfonate.

★ Remove the high-pressure tank (see Figure 12 in the instrument room) and install the test piece (5) on the holder (6). The sample requirements: the sample should be clean, the surface should be free of dirt, no visible dirt or creases, and must not be folded , And it should be placed on a flat place without any load on it. Then install the high-pressure warehouse, and then tighten the high-pressure warehouse nuts in balance.

★ Open the water valve (3) and fill the clean water source from (1) ** Pressurized water tank (2). Until the water level difference on both sides reaches 50mm (11). Turn off the water supply. If the water heads on both sides of the sample cannot be balanced within 5 minutes, look for unclean air. Open the (13) exhaust valve and exhaust again. And indicate in the test report.

★ Adjust the water flow so that the head difference reaches 70mm ± 5mm and record this value. ** to 1mm. After the water head has stabilized for 30s, within a specified period of time, the graduated cylinder collects (8) the amount of osmotic water passing through the osmotic water collection tube, with a volume of ** to 10mL and a time of ** to s.

★ 0.8 times, 0.6 times, 0.4 times and 0.2 times the head difference for A large head. Repeat the procedure in 2.3.4 above, from the beginning of A high flow rate to the end of A low flow rate, and record the corresponding amount of permeate and time.

★ Record water temperature, ** to 0.2 ° C.

★ The calculation of results should be based on the corresponding standards of T1141-2006.
