Construction method and application of salinized soil roadbed
The invention discloses a construction method and application of a salinized soil roadbed, and relates to the technical field of salinized soil roadbed construction. The construction method of the salinized soil roadbed comprises the steps that an alkali drainage channel foundation pit is excavated on at least one side of the roadbed, geotechnical cloth is laid at the bottom of the alkali drainage channel foundation pit to serve as a water-resisting layer, the two sides of the alkali drainage channel foundation pit are filled with gravel edge covering soil, the middle of the alkali drainage channel foundation pit is backfilled with aeolian sand, and shaping and rolling are conducted after paving and leveling are conducted. By excavating the alkali drainage channel, the underground water level of the roadbed along the line can be reduced, the gravel edge covering soil and the aeolian sand can effectively block capillary water from rising and guarantee dryness of the roadbed, the strength of the roadbed is guaranteed through the specific backfilling positions of the gravel edge covering soil and the aeolian sand, the gravel edge covering soil and the aeolian sand in the Xinjiang region are rich in reserves and low in price, and local materials are easy to use. The construction method is simple in process, easy to operate and remarkable in effect of treating the salinized soil roadbed; and the construction quality is easy to control, and the method can be widely applied to salinized soil roadbed construction.
本发明公开了一种盐渍土路基的施工方法及其应用，涉及盐渍土路基施工技术领域。该盐渍土路基的施工方法包括：在路基的至少一侧开挖排碱渠基坑、对所述排碱渠基坑的底部铺设土工布作为隔水层，对排碱渠基坑的两侧填筑砾石包边土，向排碱渠基坑的中部回填风积沙，摊铺整平后整型碾压。本申请通过开挖排碱渠，有利于降低沿线路基的地下水位，砾石包边土和风积沙可以有效阻断毛细水上升，保证路床的干燥，并且砾石包边土和风积沙特定的回填位置保证了路基的强度，新疆地区砾石包边土及风积沙储量丰富，价格便宜，易于就地取材。该施工方法工艺简练，操作简单，用于处理盐渍土路基效果显著；施工质量易于控制，可广泛应用盐渍土路基施工中。
