Ecological soil body reinforcing method for seasonal frozen soil region
The invention discloses an ecological soil body reinforcing method for a seasonal frozen soil region, which comprises the following steps: adding xanthan gum and polyanionic cellulose gel into soil to be improved, stirring, compacting and then heating and curing, so that the curing process of the xanthan gum is accelerated, higher initial strength is provided, and the soil to be improved is improved. The adverse effect of freezing and thawing cycle on the strength property of the soil body can be effectively reduced; by means of the reinforcing method, formation of uneven aggregates is avoided, the compact soil aggregates are prepared, the strength of the soil body is still kept unchanged under freezing and thawing cycles, and the reinforcing method is extremely suitable for being applied to infrastructure construction in the frozen soil area.
本发明公开了一种用于季节性冻土区的生态型土体加固方法，所述加固方法为采用黄原胶与聚阴离子纤维素凝胶添加进待改良土，搅拌压实后加热固化，不仅加快了黄原胶的固化进程，提供了较高的初强度，还能有效降低冻融循环给土体强度性质带来的不利影响；本发明的加固方法避免了不均匀团聚体的形成，制得致密的土壤团聚体，在冻融循环下土体强度仍保持不变，极适合应用于冻土区域的基础设施建设。
