Example Embodiment
[0023] Example 1:
[0024] A sandy soil drag reduction slurry for pipe jacking machine, made of the following parts by weight of raw materials: sodium bentonite 100kg, soda ash 0.6kg, carboxymethyl cellulose 0.2kg, potassium humate 0.2kg, graphite powder 0.1 kg, vegetable glue 10kg, water 280kg.
[0025] As mentioned above, the preparation method of drag reduction mud for pipe jacking machine in sandy soil, the specific steps are as follows: add water to the pulping device, and mix soda ash, carboxymethyl cellulose, potassium humate, graphite powder and The vegetable glue is added to the pulping device, and finally sodium-based bentonite is added. After being evenly stirred, it is put into a slurry tank. A propeller is installed in the slurry tank to continuously stir the drag reduction slurry to prevent the drag reduction slurry from settling.
