(shallow water) columnar sediment sampler Uses: Collect underwater sediments (sediments, sediments, sludge), marsh soil, and clay soil in rivers, lakes and ponds. Suitable for water depth: 5m; sampling tube: length 100cm, diameter 4cm; Stainless steel cutting head (conventional analysis sampling), engineering plastic cutting head (heavy metal analysis sampling), Standard configuration: 1 hitting handle, 1 energy-absorbing hammer, 5 1 meter long extension rod, 1 sampler (with stainless steel cutting head), 2 engineering plastic cutting heads, 2 sampling tubes, 4 Spare piston, 1 anti-stretch rope, 1 scraper, 1 steel tape measure, 2 wrenches, 1 pair of gloves, 1 aluminum box. Instructions: 1: Pass the piston rod through the holder, then install the piston on the piston rod, then insert the piston and piston rod into the sampling tube. 2 sets of upper cutting heads, and then the cutting head, the sampling tube and the holder are fixed together by a steel belt. 3: Connect the extension cord to the top of the piston rod. 4: Connect the extension rod and T-handle according to the actual situation, push the piston to the bottom of the sampling tube before sampling. 5: After determining the sampling location, insert the sampling tube vertically into the water, and feel that the sampler is not sinking (the cutting head has entered the mud), and raise the sampler by about 10-20 cm, then about 10-20 cm. Determine the new sampling point. 6: Tighten the extension rope and fix it so that the piston position is relatively fixed. Then push the T-handle down firmly to make the sampling tube enter the sediment. After reaching the predetermined sampling depth, fix the extension rope to the extension rod or handle. Above, the sampler is proposed to complete one sampling.
