Structural parameters and model construction of a new root-like dehydration tube

To ensure the dehydration rate of the new root-like dehydration tube, the range of structural parameters of the dehydration tube is drawn up according to the existing test conditions, and the branch tube layout plan is formulated. On this basis, the dehydration test plan is designed, the influence of structural parameters on the dehydration rate of the new root-like dehydration tube was studied by controlling variables, and a dehydration model was constructed. The results show that the dehydration rate increases with the increase of branch tube length, and increases first and then decreases with the increase of the number of branch tubes in the same layer and the distance between upper and lower branch tubes. After regression analysis of the experimental data, the dehydration model of the new root-like dehydration tube is obtained, and the optimal structural parameters are obtained by taking extreme values for the constraints of the dehydration model. It is found that the full-section umbrella layout of branch tubes in the same layer can improve the dehydration rate of the new root-like dehydration tube. The research results can be used as the basis for judging the dewatering effect of backfilling, and can also be used to guide enterprises to manufacture new root-like dehydration tubes.
