Rapid treatment method for slurry of cast-in-situ bored pile
The invention discloses a cast-in-situ bored pile slurry rapid treatment method which comprises the following steps: firstly, adding a chemical flocculant into drilling slurry according to a ratio, stirring for reaction, and standing for precipitation to realize rapid separation of slurry water and slurry precipitates; then, the drilling mud sediment is taken and mixed with quick lime according to the mass proportion, rapid drying of the mud sediment is achieved, and high-dosage lime stabilized soil is prepared; secondly, uniformly mixing the high-mixing-amount lime stabilized soil with clay according to the proportion to prepare lime stabilized soil with a common mixing amount; and finally, according to a construction rolling technology of the lime stabilized soil, using the lime stabilized soil with a general mixing amount as a road subgrade filling material. According to the scheme, the waste slurry generated in the construction process of the cast-in-situ bored pile can be rapidly treated, the lime stabilized soil is prepared to be used as a roadbed filling material in road construction, and rapid treatment and recycling of the slurry of the cast-in-situ bored pile are achieved.
本发明公开了一种钻孔灌注桩泥浆快速处理方法，所述钻孔灌注桩泥浆快速处理方法包括：首先，根据配比在钻孔泥浆中加入化学絮凝剂搅拌反应并静置沉淀，实现泥浆的水和泥浆沉淀物的快速分离；然后，取钻孔泥浆沉淀物掺入质量比例的生石灰，实现泥浆沉淀物的快速干燥，制备高掺量石灰稳定土；其次，根据配比将高掺量石灰稳定土与黏土均匀混合，制备一般掺量的石灰稳定土；最后，根据石灰稳定土的施工碾压技术，将一般掺量石灰稳定土用作道路路基填筑材料。本方案可对钻孔灌注桩施工过程中产生的废弃泥浆进行快速处理，制备石灰稳定土用于道路施工中的路基填筑材料，实现钻孔灌注桩泥浆的快速处理和再利用。
