Blending method for improving mix proportion of bentonite to undisturbed soil in anti-seepage cushion layer
The invention discloses a blending method for improving the mix proportion of bentonite to undisturbed soil in an anti-seepage cushion layer. The blending method comprises the following steps that before trial blending and construction, sodium bentonite is detected, and the sodium bentonite is accepted and accepted after performance parameter indexes of the sodium bentonite are reached; in the trial and actual construction process, the undisturbed soil is detected at any time, and the undisturbed soil is accepted and accepted after performance parameter indexes of the undisturbed soil are achieved; before the mixed soil is backfilled, sodium bentonite and undisturbed soil which are accepted and accepted are evenly stirred and compacted through a mixing machine, and the mass mix proportion of the bentonite to the undisturbed soil is 1 to 11.5; and in the construction process, a project manager detects the compaction coefficient and the permeability coefficient of the compacted mixed soil, and when the compaction coefficient and the permeability coefficient do not meet the preset requirements, the proportion can be adjusted in time, and the project quality is guaranteed. The blending method for improving the mix proportion of the bentonite to the undisturbed soil in the anti-seepage cushion layer has good anti-seepage performance.
本发明公开了一种用于改良防渗垫层中膨润土与原状土配合比调配方法，包括以下步骤，在试配及施工之前，检测钠基膨润土，达到钠基膨润土的性能参数指标后验收合格；在试配及实际施工过程中，随时检测原状土，达到原状土的性能参数指标后验收合格；在混合土回填之前，将验收合格的钠基膨润土和原状土运用拌合机搅拌均匀并压实，质量配合比为膨润土：原状土＝1:11.5；施工过程中，工程管理人员检测压实后混合土的压实系数、渗透系数，当不符合预设要求时，能够及时调整配比，保证工程质量。本发明具有很好的防渗性能。
