Method for filling subgrade in soil and stone combined water
The invention discloses an earth-rock combined underwater roadbed filling method. The earth-rock combined underwater roadbed filling method comprises the following steps: S1, building a cofferdam; s2, draining and dredging; s3, the rockwork is replaced and filled; s4, the subgrade in water is constructed in a soil and stone combined mode; the subgrade in water comprises two protection feet, two inverted filter layers and an earthwork area, the two protection feet are located on the water facing sides of the two sides of the subgrade and formed by stone filling, the two inverted filter layers are located on the inner sides of the two protection feet respectively and formed by first clay filling, and the earthwork area is located between the two inverted filter layers and formed by second clay filling; the water permeability of the first clay is smaller than that of the second clay. The technical problem that the stability of the subgrade in water cannot be guaranteed due to the fact that the usage amount of stone is reduced in a stone shortage area is solved.
本申请公开了一种土石结合水中路基填筑方法。该土石结合水中路基填筑方法包括以下步骤：S1、围堰修筑；S2、排水清淤；S3、换填石方；S4、采用土石结合的方式进行水中路基的施工；所述水中路基包括：两护脚、两反滤层和土方区，其中，两护脚位于路基两侧的临水侧，且采用石料填筑形成，两反滤层分别位于两护脚的内侧，且采用第一粘土填筑形成，土方区位于两反滤层之间，且采用第二粘土填筑形成；所述第一粘土的透水性小于所述第二粘土的透水性。本申请解决了在石方短缺地区减少石方使用量无法保证水中路基的稳定性的技术问题。
