TST-70 soil permeameter

Product Information

The TST-70 soil permeameter complies with the GB9357-77 standard and meets the requirements of the "Soil Test Code" (SL237-1999) and the "Highway Soil Test Code". The soil permeameter (T0129-93) of the 70 type soil permeameter is used to conduct permeability tests on sandy soil and non cohesive soil containing a small amount of gravel under constant water head. The TST-70 soil permeameter is manufactured based on the Shima permeameter, with an inner diameter of φ 100+0.22mm. It can be used to measure the permeability of sandy soil and non cohesive soil containing a small amount of gravel under constant water head. The soil permeameter mainly consists of a permeable component and a compaction component. The permeable component of the 70 type soil permeameter consists of a cylinder body, a permeable plate, a scale plate, a pressure measuring tube, etc. Three pressure measuring tubes are installed on the scale plate with a spacing of 100 ± 0.44mm. The water level can be read by the scale of the scale plate installed on the cylinder. Copper wire cloth is installed in the joint of the pressure measuring tube to prevent fine sand particles from flowing out with water during the test. There is a drainage hole at the lower part of the infiltration tube, and loosening the bolt can release the sewage. The compaction part is equipped with a wooden hammer to compact the sample.

Technical Specifications:

1. Inner diameter of the cylinder: φ 100+0.22mm. Infiltration tube height: 400mm

2. Distance between pressure measuring tubes: 100 ±. 44mm

Note: The complete set of instruments, accessories, and spare parts includes one water permeable component, wooden hammer, pipe clamp, pressure measuring tube, rubber tube (1.5 meters long), and two pieces of copper wire mesh 0.5 × 0.6 (20 #) and 1 × 1 (40 #).
