Gabion structure for preventing frost heaving damage of flood drainage channel in alpine region and construction method
The invention relates to a gabion structure for preventing frost heaving damage of a flood drainage channel in an alpine region and a construction method. Geotechnical cloth is laid at the bottom of the flood drainage channel, a bottom gabion net cage is placed on the geotechnical cloth, a left gabion net cage is placed on the left side above the bottom gabion net cage, and a right gabion net cage is placed on the right side above the bottom gabion net cage; the tops of the right gabion net cage and the left gabion net cage are aligned with the top of the flood drainage channel; filling pebbles are filled in the bottom gabion net cage, the left gabion net cage and the right gabion net cage; backfill soil is arranged between the bottom gabion net cage and the left side gabion net cage and the left slope of the flood drainage channel, and backfill soil is arranged between the bottom gabion net cage and the right side gabion net cage and the right slope of the flood drainage channel; and a geomembrane is arranged between the backfill soil and the net cage. The method is reasonable in design and convenient to implement, and the problem of water and soil loss caused by flushing of the flood drainage channel slope bank can be effectively prevented; and the construction safety and effectiveness of the flood drainage channel and the flood bank can be guaranteed simultaneously. The method is especially suitable for the northwest region frost heaving soil environment.
本发明涉及高寒地区防止排洪渠冻胀损坏的石笼结构及施工方法，在排洪渠渠底铺设有土工布，土工布上放置有底部格宾网箱，底部格宾网箱上方的左侧放置有左侧格宾网箱，底部格宾网箱上方的右侧放置有右侧格宾网箱，右侧格宾网箱和左侧格宾网箱的顶部与排洪渠顶部对齐，底部格宾网箱、左侧格宾网箱和右侧格宾网箱中装有填充卵石；底部格宾网箱和左侧格宾网箱与排洪渠左边坡之间有回填土，所述底部格宾网箱和右侧格宾网箱与排洪渠右边坡之间有回填土；所述回填土与网箱之间设有土工膜。本申请设计合理，实施方便，能够有效地防止排洪渠坡岸被冲刷导致的水土流失问题；有利于同时保障排洪渠防洪堤施工安全性和有效性。尤其适用于西北地区冻胀土环境。
