Method for preventing outward liquid seepage of Bayer process red mud-based roadbed
The invention provides a method for preventing outward liquid seepage of a Bayer process red mud-based roadbed, and relates to the technical field of roadbed seepage prevention. The method for preventing outward liquid seepage of the Bayer process red mud-based roadbed comprises the following steps that S1, a roadbed foundation pit is excavated according to design requirements; S2, the bottom of the roadbed foundation pit is cleaned; S3, after the bottom of the foundation pit is cleaned, the bottom of the foundation pit starts to be backfilled, and a backfilling layer is compacted and leveledthrough a machine; S4, after backfilling is finished, an inner protective wall is poured on the side, close to a new foundation, of an original foundation; S5, an outer protective wall is poured on the outer side of the roadbed foundation pit; S6, a concrete anti-seepage layer is poured at the top of the backfilling layer; and S7, two layers of anti-seepage geotextile are laid on the upper side ofthe concrete anti-seepage layer. Through the construction method designed by the invention, outward liquid seepage of the Bayer process red mud-based roadbed can be effectively prevented, it is ensured that no pollution is caused to the geological environment during construction, and the method is simple in step and convenient to operate.
本发明提供一种防止拜耳法赤泥基路基外渗液的方法，涉及路基防渗技术领域。该防止拜耳法赤泥基路基外渗液的方法，包括以下步骤：S1.按照设计要求开挖路基基坑;S2.对路基基坑底部进行清理;S3.在基坑底部清理完成后，开始对基坑底部进行回填，并且使用机械对回填层进行压实整平;S4.回填结束后，在原地基靠近新地基一侧浇筑内保护壁;S5.在路基基坑靠外侧浇筑外保护壁;S6.在回填层顶部浇筑一层混凝土防渗层；S7.在混凝土防渗层的上侧铺设两层防渗土工布。通过本发明设计的施工方法可以有效防止拜耳法赤泥基路基外渗液，保证了施工时不会对地质环境造成污染，而且该方法步骤简单、操作方便。
