Embedded anchoring-buttress type combined retaining wall structure and construction method
The invention discloses an embedded anchoring-buttress type combined retaining wall structure and a construction method, and belongs to the technical field of geotechnical engineering. A plurality of parallel inclined buttresses are arranged on the inner side of a buttress type retaining wall. A vertical face of the buttress type retaining wall is provided with reserved anchor cable holes, and the inner side of the buttress type retaining wall is a backfilled gravel soil layer. The backfill gravel soil layer is provided with a groove body, and the groove body comprises an anchor cable free groove, an anchor cable anchoring groove and an expansion head groove. The inner end of the anchor cable forms an anchor cable anchoring section and an expansion head in the anchor cable anchoring groove and the expansion head groove by pouring cement mortar. A plurality of steel strands at the outer end of the anchor cable penetrate through the anchor cable free groove and are fixed to the anchor head through reserved anchor cable holes. A plurality of steel strands in the anchor cable free section and the anchor cable anchoring section are supported in the groove body through a plurality of centering supports. The invention further provides a construction method. The pre-stressed anchoring technology is combined with a traditional buttress type retaining wall to work, so that the problems that a high buttress type retaining wall is poor in stability, large in size, high in manufacturing cost and the like when working independently are solved. The construction time is short, the engineering cost is low, and the quality is good.
预埋式锚拉‑扶壁式联合挡土墙结构及建造方法，属于岩土工程技术领域，扶壁式挡土墙内侧有多个并列倾斜的扶壁。扶壁式挡土墙的立面上有预留锚索孔，其内侧为回填碎石土层。回填碎石土层开有槽体，槽体包括锚索自由槽、锚索锚固槽和扩大头槽。锚索内端在锚索锚固槽内和扩大头槽内通过浇筑水泥砂浆形成锚索锚固段和扩大头。锚索外端的多束钢绞线穿过锚索自由槽，通过预留锚索孔和锚头固定。锚索自由段和锚索锚固段中的多束钢绞线由多个对中支架支撑在槽体内。本发明还提供建造方法。预应力锚拉技术与传统扶壁式挡墙联合工作解决了高扶壁式挡墙单独工作稳定性差、尺寸大和造价高等问题。施工耗时短，工程成本低，质量好。
