Embankment structure combining cohesive soil and mucky soil and construction method of embankment structure
The invention provides a cohesive soil and mucky soil combined embankment structure and a construction method thereof.The embankment structure comprises a main embankment body, an outer platform arranged on the outer side of the main embankment body and an inner platform arranged on the inner side of the main embankment body, the main embankment body is formed by filling cohesive soil, and the outer platform comprises an outer platform body; the outer platform comprises an outer platform body, the inner platform comprises an inner platform body, the outer platform body and the inner platform body are both formed by filling mucky soil, and reverse filter geotechnical cloth and a Reynolds protection pad which are used for protecting the outer platform body are laid on the upstream face of the outer platform body from inside to outside. A coarse sand cushion layer is adopted on the lower portion of the inner platform body to assist in drainage, drainage consolidation of mucky soil in the construction period and drainage of seepage water of an embankment body in the operation period are facilitated, and inverted filter geotechnical cloth is laid at the joint of the coarse sand cushion layer and soil materials. In order to prevent the platform built by mucky soil from generating shrinkage cracks, the tops of the inner platform and the outer platform are sealed by adopting cohesive soil protective layers, and grass is planted on the tops of the inner platform and the outer platform. The invention further discloses a construction method for building the dike.
本发明提供一种粘性土和淤泥质土相结合的堤防结构及其施工方法，所述堤防结构包括主堤身、设置在主堤身外侧的外平台和设置在主堤身内侧的内平台，所述主堤身由粘性土填筑而成，所述外平台包括外平台本体，所述内平台包括内平台本体，所述外平台本体和内平台本体均由淤泥质土填筑而成，所述外平台本体迎水面上由内向外铺设有用于保护外平台本体的反滤土工布和雷诺护垫。所述内平台本体下部采用粗砂垫层辅助排水利于施工期淤泥质土的排水固结及运行期堤身渗水的排出，粗砂垫层与土料的接合处铺设反滤土工布；为防止淤泥质土堆筑的平台发生干缩裂缝，所述内外平台顶部均采用粘性土保护层密封并植草。还公开了建造本堤防的施工方法。
