Dam frost heaving prevention protection structure and construction method
The invention relates to the field of dam engineering, in particular to a dam frost heaving prevention protection structure and a construction method.The dam frost heaving prevention protection structure comprises a coarse aggregate layer, a fine aggregate layer, a backfill soil layer, an anti-freezing assembly and a drainage assembly, the backfill soil layer is located at the bottommost layer of a dam, the fine aggregate layer is arranged above the backfill soil layer, and the coarse aggregate layer is arranged above the fine aggregate layer; the drainage assembly is pre-buried in the backfill soil layer, the anti-freezing assembly is pre-buried in the dam and penetrates through the three soil layers, the arrangement of the soil layers can reduce the possibility of frost heaving of the whole dam to a certain extent, and when the whole dam is subjected to frost heaving, the anti-freezing assembly can be started in time to melt frozen water in the dam, so that the anti-freezing effect is achieved. And melted water can be treated by the drainage assembly, so that the possibility that the dam is damaged by a frost heaving phenomenon is effectively reduced. The method has the effect that the problem that in the related technology, only frost heaving is prevented, corresponding measures are difficult to take at the first time when the frost heaving problem is found, and then the possibility that the dam is seriously damaged is increased is solved.
本申请涉及堤坝工程领域，尤其是涉及一种堤坝防冻胀防护结构及施工方法，包括粗骨粒层、细骨粒层、回填土层、防冻组件以及排水组件，回填土层位于堤坝的最底层，回填土层上方是细骨粒层，细骨料层上方是粗骨粒层，排水组件预埋在回填土层中，防冻组件预埋在堤坝内贯穿三种土层，土层的设置就能够一定程度上减小堤坝整体发生冻胀的可能性，当堤坝全部发生冻胀时，防冻组件会及时启动，将堤坝内冻结的水份融化，融化后的水分会被排水组件处理掉，进而有效地减小了堤坝被冻胀现象破坏的可能性。本申请具有解决了相关技术中仅是预防冻胀，难以在发现有冻胀问题产生的时候第一时间采取相应的措施，进而增加了堤坝受到严重破坏的可能性的问题的效果。
