浆砌石加筋挡土墙的水力冲填施工方法研究

Research on hydraulic flushing and filling construction method of reinforced retaining wall with mortar masonry

在河道堤防工程的建设中,加筋挡土墙后土体的回填是关键的施工环节,传统的水力冲填方法存在稳定性不足和支撑性弱的问题。本研究针对现有竖向水力冲填设计的不足,提出了一种浆砌石加筋挡土墙后土体回填的水力冲填施工新技术。该技术通过引入条形支撑和辅助支撑平台,优化了冲填结构,提高了工程的稳定性和荷载力。通过地质勘察确立基础布置,精确计算填土量,并采用多点位压力胶管进行冲填,施工完成后,通过严格的质量核验,确保了施工质量。在河道堤防工程的应用实例中,7个测试点位的冲填密实度均超过了15.5%,验证了本方法的灵活性、针对性和实际应用价值。

In river embankment engineering,the backfilling of soil behind reinforced retaining walls usually relies on hydraulic flushing support platforms.However,current designs mainly focus on vertical forms,resulting in relatively weak load forces.In response to this issue,this article conducts in-depth research on the hydraulic backfill construction technology of the soil behind the reinforced retaining wall with mortar masonry.In order to significantly improve the load capacity,strip support and auxiliary support platforms are introduced as optimization measures.Through excavation treatment,precise calculation of soil filling amount,use of multi-point pressure rubber hoses for flushing and filling,and strict quality verification,the flushing and filling construction treatment has been successfully implemented.The example analysis results show that the compaction degree of the 7 test points exceeds 15.5,proving that this method is flexible and highly targeted,and has significant practical application value.
