The invention relates to the technical field of slope protection, in particular to a composite retaining wall structure and a construction method. According to the specific technical scheme, the composite retaining wall structure comprises cast-in-place piles correspondingly arranged along the two sides of the edge of a slope body, a plurality of fixed building blocks are connected to one sides of the cast-in-place piles, and a plurality of movable building blocks are detachably connected between the cast-in-place piles and between every two correspondingly-arranged fixed building blocks; in the vertical direction, the fixed building blocks are fixed through I-shaped steel, and the movable building blocks are fixed through I-shaped steel. The self-embedded retaining wall solves the problem that an existing self-embedded retaining wall is poor in durability and firmness.

本发明涉及边坡防护技术领域，具体涉及一种复合式挡土墙结构及施工方法。具体技术方案为：一种复合式挡土墙结构，包括沿着坡体边缘两侧对应设置的现浇桩，所述现浇桩的一侧连接有多个固定砌块，所述现浇桩之间、对应设置的两个固定砌块之间可拆卸连接有多个活动砌块，竖直方向上、所述固定砌块之间和活动砌块之间通过工字钢固定。本发明解决了现有自嵌式挡土墙耐久性和坚固性不好的问题。
