湿筛法土工布有效孔径测定仪结构与工作原理: 

★外观 

土工布有效孔径测定仪由底板、外罩、夹持器与筛分装置、喷淋系统等部分组成。 底板四角开有安装槽,可用螺栓将之固定在基础上或工作台上;外罩左上角控制区装有计数器、电源开关、启动键。外罩与筛分振动装置不直接触,减少振动影响。 

喷淋系统安装在底板右侧的支柱上,由进水口、流量开关、金属软管、莲蓬头组成,莲蓬头上配有一防溅盖,使用时莲蓬头放置于透明罩内,盖上防溅盖,并扣上夹扣,以防止水溅出。收集槽与振动头刚性联接,左侧设有收集管,收集槽底配有支持网栅,试样平铺在网栅上,用夹持器将之压紧,然后用翻转螺栓和星形把手压紧。 

 翻转螺栓和星形把手的具体操作方法为:由于收集槽与夹持器间的防渗水要求,其外壁安装有密封圈,因此有两只启盖螺栓上开有长口槽,当夹持器难以取出时,可利用启盖螺栓反向旋转,其卡口会提升起夹持器,以方便操作。 

★土工布有效孔径测定仪传动系统: 由附着式混凝土振动器通过皮带——齿轮带动偏心轮转动以带动振动头产生一定振频与振幅振动。电机与振动元件分离安装,平板与底板通过四个弹簧减振柱支承。振动头与平板也采用弹簧减振柱联接,以减少振动对仪器的影响。  

Structure and working principle of wet sieve geotextile effective aperture tester:

★ Appearance

The geotextile effective aperture tester is composed of a bottom plate, a cover, a holder and a sieving device, and a sprinkler system. There are mounting slots at the four corners of the bottom plate, which can be fixed to the foundation or the workbench with bolts; the control area at the upper left corner of the cover is equipped with a counter, power switch and start key. The outer cover is not in direct contact with the screening vibration device, reducing the impact of vibration.

The spray system is installed on the pillar on the right side of the bottom plate. It consists of a water inlet, a flow switch, a metal hose, and a shower head. The shower head is equipped with a splash-proof cover. When in use, the shower head is placed in a transparent cover and covered with a splash-proof cover. Attach the clip to prevent water from splashing. The collection tank is rigidly connected to the vibrating head. A collection tube is provided on the left side. The bottom of the collection tank is equipped with a supporting grid. The sample is laid on the grid and compressed with a clamper. Tighten.

 The specific operation method of the flip bolt and the star handle is: due to the water-proof requirement between the collecting tank and the holder, the outer wall is equipped with a sealing ring, so there are two long opening grooves on the cap screws. When the device is difficult to remove, the cap screw can be used to rotate in the opposite direction, and its bayonet will lift the holder for easy operation.

★ Geotextile effective aperture tester transmission system: The attached concrete vibrator drives the eccentric to rotate through the belt-gear to drive the vibrating head to generate a certain frequency and amplitude vibration. The motor and the vibration element are separately installed, and the flat plate and the bottom plate are supported by four spring damping columns. The vibration head and the flat plate are also connected by a spring damping column to reduce the impact of the vibration on the instrument.

Operation steps of wet sieve geotextile effective aperture tester:

★ Remove the holder, lay the sample flat on the support grid flat without force, and then compress it with the holder. The sample should be kept horizontal.

★ Spread the granular material selected according to the standard evenly on the sample.

★ The water inlet is externally connected to a regulated water source. The shower head is placed in a transparent cover, covered with a splash-proof cover, and the clip is closed. The flow regulating valve is opened to spray water on the sample.

★ Set the vibration time on the timer (according to GB / T17634-1998 standard, it can be set to 600 seconds, the instrument timer has two gears, which can be set to 0-99.99s and 0-99 minutes and 59s respectively). . Turn on the power and start the test.

★ The particles passing through the sample flow out of the collection tank and are collected.

★ When the set time is reached, stop the instrument from vibrating.

★ Collect failed particulate materials and samples.

★ Reload the sample and press the start key to reset.

★ Test results are processed according to GB / T17634-1998 standard.

★ After the instrument is finished, turn off the power and clean the instrument.
