Water conservancy project combined retaining wall structure and construction method thereof
The invention relates to the technical field of water conservancy projects, in particular to a water conservancy project combined retaining wall structure and a construction method thereof. The water conservancy project combined retaining wall structure is used for river channel protection, the water conservancy project combined retaining wall structure comprises fish nest bricks, gravel inverted filter layers, geogrids, a concrete base and a gabion layer, the adjacent fish nest bricks are distributed in a staggered mode and are integrally distributed in a 120-degree staggered mode, and the geogrids are distributed on the sides of the fish nest bricks at equal intervals. A second backfill soil layer is arranged between the adjacent geogrids, the gravel inverted filter layers are further arranged between the fish nest bricks and the second backfill soil layer, and the gravel inverted filter layers are located between the adjacent geogrids. According to the structure, the gabion layer is built above the second backfill soil layer behind the fish nest bricks, so that the friction force and the soil pressure of the upper layer soil in the backfill soil on the geogrids can be increased, and the tensile stress of the upper layer geogrids on the retaining wall formed by the fish nest bricks is ensured. The fish nest bricks distributed in a staggered mode can enhance the stability of the wall body and provide a habitat for aquatic animals and plants.
本发明实施例涉及水利工程技术领域，尤其涉及一种水利工程组合挡土墙结构及其施工方法，用于河道防护，包括鱼巢砖、碎石反滤层和土工格栅，相邻所述鱼巢砖之间错开分布，且整体呈120错台分布，所述土工格栅等距离分布于鱼巢砖一侧，相邻所述土工格栅之间设置有第二回填土层，所述鱼巢砖和第二回填土层之间还设置有碎石反滤层，且碎石反滤层位于相邻土工格栅之间，还包括：混凝土底座以及石笼层。本发明通过将石笼层砌筑于鱼巢砖后第二回填土层的上方，可增大回填土中上层土壤对土工格栅的摩擦力及土压力，从而保证上层土工格栅对鱼巢砖构成的挡墙的拉应力，且呈错台分布的鱼巢砖可以起到增强墙体的稳定性并为水生动植物提供栖息地。
