Anti-scour structure of banket for embankment and construction method
The invention provides an anti-scour structure of a banket for an embankment and a construction method and relates to the technical field of embankment engineering. The construction method comprises the following steps of determining structural parameters of a key wall; excavating a foundation pit; constructing the key wall; and carrying out back-fill consolidation on construction spaces on two sides of the key wall and the construction foundation pit. In the anti-scour structure of the banket for the embankment constructed by the construction method, the side, facing a slope toe, of the key wall is a bevel, and the included angle formed between the bevel and the surface of a bank slope is an obtuse angle, so that the key wall is in direct contact with the slope toe. Meanwhile, the bevel of the key wall disperses gravity to the slope toe, so that a suspending phenomenon of the key wall as a result of uncompacted backfilled soil texture at the slope toe is avoided and the anti-scour structure of the banket for the embankment is prevented from being damaged, and therefore, the safety and stability of the embankment are further improved effectively.
本发明提供了一种堤防护脚防冲结构及施工方法，涉及堤防工程技术领域。该施工方法包括确定齿墙的结构参数；开挖基坑；筑建齿墙；待齿墙达到设计强度后，对齿墙与施工基坑两侧的施工空间进行回填夯实。使用该施工方法筑建的堤防护脚防冲结构中，齿墙朝向坡脚一侧为斜面，斜面与岸坡表面之间形成的夹角为钝角，进而实现齿墙与坡脚直接接触，同时齿墙的斜面将重力分散在坡脚上，避免了齿墙因坡脚处回填土质不密实而导致的悬空现象，保护堤防护脚防冲结构不被破坏，进而有效的提高了堤防的安全稳定。
