Pipe jacking construction is a non-excavation construction method. Pipe jacking construction is a non-excavation construction method. It is a pipeline buried facility technology that does not excavate or less excavation.
Product introduction
The coal-based Net Gas Granular Activated Carbon with high quality anthracite as raw material, by block crushing production technology refined processing; the appearance is black particles. It has large pore specific surface area and specific volume, reasonable pore structure, good adsorption properties, high mechanical strength, good wear resistance, structural stability, small gas resistance, easy regeneration, low regeneration loss, low cost, not easy to break under high pressure and high temperature and other characteristics.
The pipe jacking method is to overcome the friction between the pipe and the surrounding soil by means of the jacking force generated by the jacking equipment in the working pit, and the pipe is pushed into the soil according to the designed slope, and the earth is removed.
After a pipe has been completed into the soil layer, the second section of the pipe continues to jack up.
The principle is to push the tool tube or the roadheader from the working pit through the soil layer to the receiving pit by means of the thrust of the main top cylinder and the pipeline, the relay room, etc., and at the same time, follow the tool pipe or the tunneling The pipe behind the machine is buried between the two pits.

4. The coal-based net gas granular activated carbon used for biochemical, paint industry, underground sites, leather factories, animal breeding sites for air purification and deodorization.
Process
Coal-based granular activated carbon with high quality anthracite as raw material, it produced by high temperature steam, and by carbonization, activation, crushing and sieving process.
Transportation and Packing
Woven bag, lined with plastic film bags, each 20kg can also be packaged according to customers demand, the product should be placed in a cool and dry place in storage.
When transportation, the product should prevent from mixing with hard material, prevent breakage, leakage or mixed with debris that affect the quality. Far away from water soaking, oil and fire.
